Description

Image registration method and device

Technical Field

The application relates to the technical field of medical treatment, in particular to an image registration method and device.

Background

The image registration is a process of performing spatial matching on two images, and if the image A is to be registered to the image B, the image A is registered to the image B by taking the image B as a reference image and taking the image A as a floating image, so as to obtain a deformation field of the image A registered to the image B. The medical image registration technology is the basis of medical image processing and plays an important role in the fields of image information fusion, auxiliary diagnosis, operation planning, medical basic theory research and the like.

There are several ways to manually register the two images, and the operator can choose according to his own preference. In one image display mode, two images are displayed in superposition, the transparency of the images is adjusted by adjusting the slider to enhance the display of an image, for example, in registration with an electron computed tomography (Computed Tomography, CT) image and a cone beam electron computed tomography (Cone beam Computed Tomography, CBCT) image, the CT image is displayed (CBCT image is fully transparent) when the slider is adjusted to the far left, and the CBCT image is displayed (CT image is fully transparent) when the slider is adjusted to the far right.

When the image configuration is performed in this display mode, the operator needs to continuously drag the slide bar (adjust the transparency, from 0% to 100% or from 100% to 0%), observe whether the two images are aligned, manually adjust the images if not aligned, and then repeat the above procedure until the two images are completely aligned.

203. And carrying out image registration on the target object according to the first target observation image.

In the embodiment, a first medical image and a second medical image of a target object to be registered are acquired; outputting a first target viewing image to a display device according to the first medical image and the second medical image to alternately display the first medical image and the second medical image on the display device; and carrying out image registration on the target object according to the first target observation image. According to the image registration method and device, the first target observation image of the first medical image and the second medical image is alternately displayed to the display device through output, and because the operator can synchronously and manually adjust the image position in the alternate display process of the first medical image and the second medical image, the time for image adjustment is saved.

In step 201, the target object may be a certain tissue or organ of the human body, such as a skull, a lung, a liver, or the like, and the first medical image and the second medical image are both medical images of the target object, i.e., medical images of the same tissue or organ, such as medical images of the brain of the user.

Specifically, the first medical image and the second medical image may be two-dimensional images or three-dimensional images in terms of dimensions, and may be CBCT images, CT images, ultrasound images (B-ultrasound images or color ultrasound images), magnetic resonance images, or the like in terms of image types, which are not limited herein. In addition, the first medical image and the second medical image may be the same type of medical image, for example, the first medical image and the second medical image are both CBCT images, the first medical image and the second medical image may also be different types of images, for example, the first medical image is a CBCT image, the second medical image is a CT image, etc., which is not limited herein.

The first medical image and the second medical image may be acquired by the image acquisition device in real time, or one of the first medical image and the second medical image may be acquired by the image acquisition device, and the other is a history medical image of the target object, or of course, both may be history medical images, which may be specifically used according to an actual scene, and the present invention is not limited herein.

In addition, in image registration, one image is generally used as a reference image, the other image is used as a floating image, which is also called a primary image and a secondary image, and in this embodiment of the present application, the first medical image may be a primary image or a secondary image, and the second medical image may be a primary image or a secondary image corresponding to the primary image or the secondary image, which is not limited herein specifically.

In step 202, the first target observation image may be an image that is alternately output by the first medical image and the second medical image, or may be a dynamic image that is synthesized by the first medical image and the second medical image, and in this case, various implementations are also described below for outputting the first target observation image to the display device according to the first medical image and the second medical image in step 202.

(1) The first target observation image may be an image in which the first medical image and the second medical image are alternately output.

The outputting the first target observation image to the display device according to the first medical image and the second medical image includes: acquiring a preset image output time interval; and according to the image output time interval, the first medical image and the second medical image are sequentially used as a first target observation image and are output to the display device.

The first target observation images alternately output by the first medical image and the second medical image are output to corresponding interfaces in the display device to be displayed, the first medical image and the second medical image are alternately displayed according to the image output time interval, and an operator can adjust the positions of the first medical image and/or the second medical image (adjustment and display are almost real-time) while observing the displayed alternating images until the first medical image and the second medical image are completely aligned. Compared with the existing image registration mode, in the process of switching the alternative images, an operator can synchronously and manually adjust the image positions, so that the time for adjusting the images is saved, in addition, the operator can easily observe whether the first medical image and the second medical image are aligned, the transparency is not required to be adjusted repeatedly, the time for image registration is saved, and the efficiency of image registration is improved.

The image output time interval is a time interval for switching between the first medical image and the second medical image, and may be preset as required, and the interval time may be 0.25 seconds, 0.5 seconds, 1 second, or the like, or may be a default value, for example, a default value of 0.25 seconds, or the like.

In one embodiment of setting the image output interval in this application, an "auto-switch" button may be set on the image registration interface of the display device, for example, after a slide bar for adjusting transparency of the medical image is set, when the "auto-switch" button is triggered, a drop-down list is displayed, where a plurality of options of 0.25 seconds, 0.5 seconds, or 1 second, etc. of alternative image output intervals are displayed, for example, after the operator selects the interval, the first target observation image under the image output interval starts to be displayed in the image registration interface.

In another mode, an "auto-switching" selection frame may be set on the image registration interface of the display device, and after selection, the first target observation image may be displayed in the image registration interface. The image output time interval may be a default value, or may be set by means of a "switching time" adjustment progress bar, a "switching time setting" button, etc., and it should be noted that in this embodiment, the interface display manner for setting the image output time interval may be various, and is not limited.

(2) The first target observation image is a dynamic image

The first target observation image may be a currently existing moving image format, such as a GIF image, or a moving image format that is newly appeared in the future, and only a moving image is needed here, which is not limited in particular

At this time, as shown in fig. 3, the outputting the first target observation image to the display device according to the first medical image and the second medical image in step 202 may further include:

301. and acquiring the preset image frame number of the first target observation image.

302. Based on the image frame number, a first number of first medical images and a second number of second medical images required to generate the first target viewing image are determined.

303. And synthesizing the first target observation image according to the first medical image number of the first number and the second medical image of the second number.

The generated dynamic images (first target observation images) are output to corresponding interfaces in a display device to be displayed, the first medical images and the second medical images are interactively displayed according to preset time intervals, and an operator can adjust the positions of the first medical images and/or the second medical images (adjustment and display are almost real-time) while observing the displayed dynamic images until the first medical images and the second medical images are completely aligned. Compared with the prior art, the technical scheme has the advantages that in the process of displaying the dynamic image, an operator can synchronously and manually adjust the position of the image, so that the time for adjusting the image is saved.

Similarly, in one embodiment, an "auto-switch" button may be provided on the image registration interface of the display device, for example, after a slider for adjusting transparency of the medical image is set, when the "auto-switch" button is triggered, a drop-down list is displayed, where a plurality of options of 0.25 seconds, 0.5 seconds, or 1 second for an image output interval are displayed, for example, after the operator selects the interval, the dynamic image under the image output interval starts to be displayed in the image registration interface.

In another mode, an automatic switching selection frame can be set on the image registration interface of the display device, and after selection, the dynamic image can be displayed in the image registration interface. The image output time interval may be a default value, or may be set by means of a "switching time" adjustment progress bar, a "switching time setting" button, or the like. In the embodiment of the present application, the interface display mode for setting the image output time interval may be various, and is not limited.

In some embodiments of the present application, the synthesizing the first target viewing image according to the first number of first medical images and the second number of second medical images includes: and synthesizing the first target observation images according to a preset quantity interval strategy by the first quantity of first medical images and the second quantity of second medical images.

Wherein the first number and the second number may be the same or different, and when the first number and the second number are the same, the synthesizing the first target observation image according to the first number of the first medical images and the second number of the second medical images may include: and synthesizing the first target observation images at intervals according to the first number of first medical images and the second number of second medical images in an equidistant mode.

The distance described in the embodiment of the present application may be a distance between two first medical images, or may be a distance between two second medical images, which may specifically be set according to an actual use scenario, and is not limited.

Specifically, for example, the first target observation image 121212,1 represents a first medical image, 2 represents a second medical image, the first medical image and the second medical image are combined at intervals of equal intervals of 1, and the first target observation image is a dynamic image composed of three first medical images and three second medical images. For example, the first target observation image 11221122 is a first target observation image obtained by synthesizing the first medical image and the second medical image at an equal interval of 2.

Since the first medical images are the primary images and the secondary images, and the primary images are not changed as the reference images, the number of frames of the secondary images in the dynamic images can be more, and therefore, in other embodiments of the present application, when the first medical images are the primary images, the second number is greater than the first number, and the secondary images as the floating images can be effectively observed.

In one embodiment, when the second number is greater than the first number, the synthesizing the first target observation image from the first number of first medical images and the second number of second medical images according to a preset number interval policy may include: and synthesizing the first target observation images according to the first number of first medical images and the second number of second medical images in a spacing increasing mode.
