Description

" A MULTI-PURPOSE RADIOLOGICAL APPARATUS "

DESCRIPTION Technical field

The present invention relates to a multi-purpose radiological apparatus, capable of performing a plurality of different radiological examinations on a patient, and a corresponding method for performing said radiological examinations.

State of the art

A multi-purpose radiological machine used to perform radiological examinations in the hospital setting can comprise a column on which a supporting member is slidingly installed; a base for an radiological sensor is hinged to said supporting member so that it can be rotated from a horizontal position into a vertical position; see, for instance, the patent application IT2003A000294 filed by the same applicant. The aforesaid type of radiological machine enables the position of the radiological sensor to be adapted to suit specific needs thanks to the different tilting angles that can be imposed on the radiological sensor; for instance, a traumatized patient may be positioned above the radiologicalsensor placed in its horizontal configuration using a radiotransparent table or stretcher separate from the machine; alternatively, the radiologicalsensor may be placed in its vertical configuration with the patient in a standing position up against it to perform radiologicalexaminations of the chest, spinal column, skull, pelvis, etc.

A radiogenic tube is provided for this type of radiologicalmachine . Said tube is arranged on a suspended system separate from the machine and centered with the radiologicalsensor so as to follow its movements. The stretcher is also separate from the machine.

Other types of multi-purpose radiologicalmachine comprise a movable supporting column with a detector, an opposite emitter and a table for supporting the patient.

US-B-6382832 describes an Radiological machine comprising a table for a patient that can be rotated around a horizontal axis, a detector arranged in the longitudinal direction with respect to the table, an X-ray emitter aligned with the detector and a frame that is adjustable in the longitudinal direction with respect to the table. The X-ray emitter is pivotally installed on the frame and associated with the table by means of a supporting column so that the distance and the alignment between the detector and the X-ray emitter remains the same when the table is tilted. The table is also associated with a base that is fixed to the floor by means of a rotating joint. In addition, the emitter is connected to the frame by means of a rotating arm with a rotating joint associated with a carriage that is vertically movable on the same frame.

A disadvantage of this radiologicalmachine lies in that it has a large maximum overall dimension, since this corresponds to the length of the supporting column, i.e. the distance between the rotating joint and the patient table. In particular, the maximum overall dimension coincides with the configuration in which the table is arranged vertically and the column horizontally. Another disadvantage lies in that this machine is complex to construct and use, since it demands a frame that is movable in the longitudinal direction and a base that is fixed to the floor, suitable for supporting and displacing the table.

Another disadvantage lies in that this radiologicalmachine enables only a limited number of different types of radiologicalexamination to be performed; for instance, it does not allow for radiographies to be taken without using the patient table.

Another disadvantage lies in that the table cannot be tilted gradually so as to arrange it in a vertical position alternately on either side of the supporting column, and this restricts the feasibility of performing some types of radiologicalexamination, such as those involving the use of contrast media, for instance.

Another disadvantage lies in that, when the table is in its horizontal configuration, it is not adjustable in height, so it may prove particularly difficult for an elderly or traumatized person to lie down thereon. Objects and summary of the invention

The object of the invention is to provide a multi-purpose radiological apparatus that is more straightforward and user-friendly and that overcomes, or at least reduces some of the aforesaid disadvantages of the 0

known radiological machines, and a corresponding method for performing radiological examinations.

Another object is to provide a multi-purpose radiological apparatus with particularly limited overall dimension in use by comparison with the known radiological machines.

A further object is to provide a radiological apparatus that is particularly compact and that enables numerous types of radiological examination to be performed.

These objects and advantages are substantially achieved by an radiological apparatus according to claim 1, and by a method for performing radiological examinations according to claim 19.

The object of the invention is a radiological apparatus comprising a supporting column that associates at least one radiological emitter with an radiological detector, and a frame that is fixed to the floor when the apparatus is in use, wherein the supporting column is designed to rotate gradually around an axis of rotation, and to move gradually along a trajectory from a maximum lowering point to at least one maximum raising point with respect to the floor, so as to pass gradually from a substantially horizontal working position into a substantially vertical working position and vice versa.

Advantageously said trajectory lies along a substantially vertical plane and may be straight or curved, e.g. semicircular. The column's axis of rotation likewise lies along a plane substantially perpendicular to said trajectory. In the preferred embodiment of the present invention, the trajectory is achieved by rotating a guide element around a further axis of rotation, and the axis of rotation gradually moves along the trajectory in order to move the column itself; the column is indirectly associated with the frame by means of said guide element. Said further axis of rotation is preferably fixed with respect to the frame and substantially parallel with respect to the column's axis of rotation; both these axes are also substantially parallel to the floor.

In an advantageous embodiment, the radiological apparatus comprises a fulcrum through which the column's axis of rotation passes, said fulcrum being designed to provide a mechanical connection between the supporting column and the guide element.

This solution allows for the use of a first drive motor for rotating the guide element around said further axis of rotation, and a second drive motor for rotating the supporting column around the column's axis of rotation.

In one embodiment of the present invention, the guide element advantageously and preferably comprises a guide wheel or disc capable of rotating inside a recess provided for said purpose in the frame, and the further axis of rotation may be a central axis of rotation for said guide wheel.

The resulting radiological apparatus is thus particularly compact and sturdy, and suitable for performing different types of radiological examination, as explained in more detail below. In another advantageous embodiment, the guide element is formed by a guide bar capable of rotating at one end around the further axis of rotation, said guide bar comprising at the other end the fulcrum of the supporting column, as explained below.

In another advantageous embodiment, the supporting column is of telescoping type to enable the distance between the radiological detector and the radiological emitter to be adjusted depending on the type of Radiological examination being performed, e.g. for chest radiological examinations, or radiological examinanationsusing contrast agents, and so on. A table or bed for a patient is preferably stably associated with the supporting column, above the radiological detector, though this does not rule out the possibility of a separate table being juxtaposed with the detector as and when necessary.

In another advantageous embodiment, moreover, the table associated with the column is movable with respect to the detector, so as to enable radiological examinations to be performed without using the table (e.g. for chest examinations with the patient standing).

In this last embodiment, the table may be displaced manually away from the detector or there may preferably be a third drive motor for tipping the table into an offline lateral position, as explained below.

Further embodiments involve further drive motors for moving (translating or rotating) the table and/or the radiological detector, and/or the radiological emitter, with respect to the supporting column, so as to enable different types of radiological examination to be performed.

According to another aspect, the invention relates to a method for performing radiological examinations, wherein the method comprises the arranging of a radiological emitter and a radiological detector so as to face one another on a supporting column, with a space in between them, the indirectly associating of the supporting column with a frame that is fixed to the floor by means of a fulcrum when the apparatus is in use, and the enabling of a first rotation of the supporting column around the further axis of rotation lying at a distance from the fulcrum.

In a particularly advantageous embodiment, a further phase comprises the enabling of a second rotation of the supporting column around the axis of rotation that passes through the fulcrum.

Said second rotation may involve at least one sub-phase for maintaining the table in its horizontal position during at least a part of the first rotation in order to avoid the table hitting the floor. The table can thus be placed as close to the floor as possible in order to facilitate the positioning of the patient thereon.

Another sub-phase of the second rotation may subsequently involve tilting or rotating the table through a given angle, depending on the type of radiological examination to be performed. Advantageous embodiments of the invention involve further phases for enabling further movements of the table and/or the detector, and/or the emitter to perform different types of radiological examination.

An advantage of the radiological apparatus according to the present invention lies in that it is more compact in overall dimensions when in use. In particular, the spaced position of the fulcrum with respect to the further axis of rotation enables a reduction in the maximum overall dimensions of the supporting column, i.e. when the column is horizontal.

Another advantage lies in that the apparatus is particularly sturdy and stable, making it possible to include further drive motors for moving the table and/or the detector, and/or the emitter, to perform different types of radiologicalexamination on a given patient, such as vertical radiological examinations on a patient standing (without the table), or oblique radiological examinations on a patient lying on the table, and so on. Another advantage lies in that the apparatus of the invention enables the use of countless types of radiological detector, of different overall dimensions and performance.

Another advantage of some embodiments of the invention lies in that the area where radiological examinations can be performed can coincide with the full extent of the table and consequently correspond to the full length of a human body, without needing to reposition the patient.

Another advantage of one embodiment of the invention lies in that the table can be lowered very close to the floor to facilitate the positioning of a patient thereon, without any risk of the table hitting the floor during said movement.

A further advantage of another embodiment lies in that it is straightforward to disengage the table from the detector in order to bring the patient's body directly into contact with the detector (positioned horizontally, vertically or tilting) so as to improve the diagnostic quality of the images in certain types of radiological examination (e.g. for chest or of an hand examinations), or in order to bring a stretcher with a traumatized patient directly over the horizontally-positioned detector without any need to move the patient.

All things considered, the radiological apparatus according to the invention is extremely compact, sturdy and versatile in use.

Further advantageous characteristics and embodiments of the method and of the apparatus according to the invention are stated in the dependent claims and further illustrated below, with reference to several non-limiting examples of embodiments. Brief description of the drawings

Detailed description of several preferred embodiments of the invention

In the drawings, where the same numbers correspond to the same parts in all the different figures, an radiological machine according to one embodiment of the invention is indicated by the numeral 1 (see Figs. 1 and

2), and comprises a frame 3 fixed stably to the floor, on which is associated a guide element that, in the embodiment described herein, comprises a guide wheel or disc 5A rotating around a further axis of rotation A1; a supporting column 7 is associated with the wheel 5A so as to enable a substantially semicircular trajectory T of the column 7. The rotating disc 5A is supported by a fifth wheel or roller bearing 6 inside a circular recess provided for said purpose on the frame 3.

One end of the supporting column 7 comprises a first horizontal bar 7A for supporting an radiological emitter 9, while at the opposite end there is associated a supporting member 15 that, in the embodiments described herein, comprises a bar lying crosswise to the column 7, with bars 15A and 15B at its respective ends for anchoring a table 13, that is located, in the arrangement shown in Figs. 1 and 2, at its maximally lowered point, at a distance "H" off the floor. The numeral 11 is used to indicate an radiological detector underneath the table, that is associated with the supporting member, or bar, 15 by means of a connecting element 15C (see also in Figs. 10 and 11) underneath the table 13 and facing towards the radiological emitter 9. Clearly, this does not rule out the possibility of the supporting member 15 comprising an element of a substantially different shape equally suitable for said purpose.

The radiological emitter 9 and the radiological detector 11 are of substantially known type, such as the flat or planar, solid-state detectors of limited overall dimensions capable of obtaining single images or sequences of images, such as the Trixell and Varian detectors, or the like.

Fig. 2 shows a side view of Fig. 1 , in which it is clear, in particular, that the supporting member 15 is associated with the guide wheel 5A by means of a fulcrum, or supporting element, 19 forming the axis of rotation A2 at one end of the column 7, and at a distance "D" from the other axis of rotation A1.

Fig. 3 shows a rear view of an radiological apparatus 1A similar to the one in Figs. 1 and 2, particularly showing a first drive motor M1A suitable for rotating the wheel 5A around the further axis A1. The first drive motor M1 A is associated with the frame 3 and comprises a pinion 21A that engages with a rack 21 B integral with the guide wheel 5A.

The rack 21 B is advantageously made with an arc of a circumference of 180° or more in order to afford a semicircular trajectory T by means of the rotation of the wheel 5A around the axis A1 through 180° or more from a maximally lowered point up to a maximally raised point. It should be noted that the rack 21 B is described herein as a nonlimiting example, since it is clearly possible to substitute it with any other type of mechanical element or device suitable for said purpose.

A second drive motor M2 is used to rotate the supporting column 7 around the axis of rotation A2: this second drive motor M2 is associated with a guide wheel 5A and mechanically connected to the fulcrum 19.

Fig. 4 shows a rear view of an radiological apparatus 1B that is an alternative to the embodiment shown in Fig. 3, comprising a first drive motor M1B associated with the frame 3 inside the guide wheel 5A that is TZIT₂OO₉ZOOO₁OO

suitable for turning said wheel 5A around the axis A1 to achieve the semicircular trajectory T; the second drive motor M2 can be substantially of the same type as the one in Fig. 3.

Fig. 5 shows a rear view of an radiological apparatus 1C that is an alternative to the previously-described embodiment, wherein the guide element is a guide bar 5B instead of a guide wheel 5A.

In particular, the guide bar 5B is hinged at one end so that it can be rotated around the axis of rotation A1 of the frame 3 by means of a first drive motor M1C in order to complete the semicircular trajectory T, and it is hinged at the opposite end to the supporting member 15 by means of the fulcrum 19 forming the axis of rotation A2.

Here again, there may be a second drive motor M2B, similar to the second drive motor M2 in Figs. 3 and 4, suitable for rotating the column 7 around the axis A2. Advantageously a further pin 20 is provided on the guide bar 5B in the vicinity of the fulcrum 19, that slidingly engages inside a groove 23 provided in the frame 3 so as to make the radiological apparatus 1 C even more sturdy and stable.

The groove 23 may be substantially circular, as shown in the figure, or it may take any other form capable of ensuring a rotation of the guide bar 5B around the axis A1 through 180° or more from the maximally lowered point to the maximally raised point.

. It should be noted that the guide wheel 5A is more sturdy in use, but also a more expensive solution than the guide bar 5B. In any case, the guide element (i.e. the bar 5B or the wheel 5A) is described herein as a nonlimiting example, since any other shape suitable for the purpose may be used.

Figs. 6 to 8 show a series of working phases of the radiological apparatus 1 according to an embodiment of the invention. In particular, Fig. 6 shows the enabling of a first rotation F1 of the column 7 around the axis of rotation A1 by means of the rotation of the wheel 5A induced by the first drive motor M1A, M1B or M1C.

During this first rotation F1 , a second rotation F2 of the column 7 is enabled around the axis of rotation A2, induced by the second drive motor M2 or M2B, which involves a first sub-phase in which the table 13 is maintained in a substantially horizontal position (Fig. 6) so as to avoid it hitting the floor.

It is thus possible to configure the machine so that the table 13 occupies a horizontal position at a very limited height "H" above the floor (see also Figs. 1 and 2) to enable a patient to lie down thereon as easily as possible.

There may subsequently be a second sub-phase in the second rotation F2 that involves gradually turning the table 13, as in Fig. 7, from the above-described horizontal position into a substantially vertical position with respect to the floor, as in Fig. 8. This second sub-phase can be enabled during or after the first rotation F1.

This does not rule out the possibility of the table 13 being maintained in a horizontal position so as to raise it to a different height off the floor to facilitate any procedures implemented by operators on the patient lying on the table.

It is worth noting that the first rotation F1 can also be enabled so that the fulcrum 19 (and the axis A2) complete a rotation greater than 90° in order to come into position above the axis A1, at a distance D2 (Fig. 8) to avoid the table 13 hitting the floor, depending mainly on the dimensions of the table 13.

Another advantageous alternative lies in that the table 13 can be placed in a tilted or raised position with respect to the floor by suitably adjusting the second sub-phase of the rotation F2 in order to complete particular types of radiological examination, such as those using a contrast medium, and so on.

It should be noted in particular that, in the case of radiological examinations with the aid of a contrast medium, it is particularly useful and effective to gradually tilt the table 13, with the patient lying thereon, to either side of the column 7, so as to optimize the effect of the contrast agent.

In any case, the first and second rotations F1 and F2 may be enabled or disabled independently of one another, or they may be enabled or disabled with a small time lag, or sequentially, or simultaneously, depending on the different needs of construction and use. Fig. 9, in particular, shows the supporting member 15, with which the table 13 is associated by means of the pair of bars 15A and 15B, and the supporting fulcrum 19 for connecting the wheel 5A to said supporting member 15. Figs. 10 and 11 show an embodiment of the invention wherein the table 13 is suitable for tipping or rotating (see arrow F3) around a tipping axis A3 lying crosswise to the column 7, so as to leave the detector 11 underneath free to use in performing radiological examinations on a patient without the aid of the table 13, e.g. for chest radiological examinations with the patient standing, and so on.

In particular, Fig. 10 shows a side view of the apparatus 1, wherein the column 7 is in a vertical configuration, but in this case, the table 13 is rotated around the tipping axis A3 into an intermediate position. Fig. 11 shows a front view of the apparatus 1 wherein the column 7 is in a horizontal configuration and the table 13 is completely rotated around the axis A3 to leave the detector 11 free.

Advantageously the tipping of table 13 is achieved by means of the rotation of the pair of bars 15A and 15B in relation to the supporting member 15, induced by a third drive motor, schematically indicated as M3 in Fig. 11 , located inside the supporting member 15.

Said tipping of the table 13 is preferably independent of the aforementioned rotations F1 and F2; for instance, the tipping action may be enabled with the table 13 in a substantially horizontal position (Fig. 10) or vertical position (Fig. 11), or in intermediate positions or tilting angles. Figs. 10 and 11 also show the connector element 15C that connects the detector 11 to the supporting member 15.

Figs. 12 and 13 show further embodiments of the invention, wherein the emitter 9 and the detector 11 are respectively movable parallel to the table 13 in order to perform oblique radiological examinations on a patient from different tilting angles.

In particular, Fig. 12 shows the column 7 displaced (in the direction of the arrow F4) along the supporting member 15 by means of a fourth drive motor M4 located inside the supporting member 15, in order to displace the emitter 9 associated with the column 7. 0

Fig. 13 shows the detector 11 displaced (in the direction of the arrow

F6) along the supporting member 15 by means of a sixth drive motor M6 located inside said supporting member 15; this last displacement can be achieved either alternatively to or jointly with the displacement of the emitter 9.

In both Figs. 12 and 13, the emitter 9 is rotated around its own axis (in the direction of the arrow F5) that is the axis of rotation A4 (see also Fig. 2) by means of a fifth drive motor M5 located inside the column 7 to remain pointed towards the detector 11. Moreover, the emitter 9 and the detector 11 may be simultaneously translated parallel to the table 13 in order to perform radiological examinations on different parts of the body without needing to move the patient; the patient can remain lying on the table or standing.

The table may also be translated manually crosswise (see arrow F6 again), e.g. by translating the table on a sliding guide with the aid of a manually-enabled table shifting and blocking system, or by means of a seventh drive motor (not shown in the figures for the sake of simplicity).

This makes it possible to perform examinations on both sides (e.g. the shoulders) of a traumatized patient by moving the table and not the patient. Similar examinations can be performed with a synchronized movement of the detector 11 and emitter 9, but this proves more complicated and costly to achieve.

Again, the column 7 is preferably of the telescoping type, enabled by an eighth drive motor (not shown on the figures), to adjust the distance between the emitter 9 and the detector 11.

All the above-described drive motors, from the first to the eighth, may be in the form of any kind of motor, e.g. electric or hydraulic, or pneumatic motors comprising transmission systems or gearing, and so on.

Moreover, some of these drive motors can be performed by a common device comprising suitable mechanical transmission systems.

The drive motors may be enabled according to any combination so as to perform different types of radiological examinatiion; for instance, the table 13 can be tipped to leave the detector 11 free, or the emitter 9 or the detector 11 can be translated in relation to the column 7, while positioning the table 13 in a horizontal or vertical or tilting configuration at the same time.

It is worth noting that at least some of these drive motors may be located inside the column 7, or inside the supporting member 15. This is on the understanding that the above description and illustrations only represent potential nonlimiting embodiments of the invention, which may vary in shape and size without departing from the scope of the inventive concept. Any use of reference numbers in the attached claims is made exclusively for the purpose of facilitating the reading of the claims in the light of the above description and attached drawings, and shall not be deemed to restrict the scope of the invention in any way.
