Description

Control system and control method to control the resonance frequency of ultrasonic therapy device {CONTROL SYSTEM AND METHOD FOR CONTROLLING RESONANT FREQUENCY OF ULTRASOUND THERAPY}

The present application relates to a control system and a control method for controlling the resonance frequency of an ultrasonic treatment device.

Ultrasound generally refers to a sound wave having a frequency exceeding 20 KHz beyond the range of an audible frequency that can be heard by a human ear, and such ultrasound is widely used in ultrasound imaging apparatuses for obtaining an image inside an object. Such an ultrasonic imaging device is compact, inexpensive, can be displayed in real time, and has the advantage of high stability because there is no exposure to X-rays, so it can be used in CT (Computed Tomography), MRI (Magnetic Resonance Image), It is widely used with other imaging devices.

Ultrasound treatment systems are mostly in the form of obtaining a therapeutic effect by irradiating the body with ultrasound having a frequency of several MHz, which is used for medical purposes, to generate vibration or heat of tissues inside the body. A representative example of such an ultrasonic treatment system is a High Intensity Focused Ultrasound System. In general, a high-intensity focused ultrasound system has a built-in transducer that emits ultrasound, and generates heat by focusing the emitted ultrasound at a focus. This causes a rapid temperature rise in the treatment area.

Tuning performed by the ultrasonic device is to scan the frequency to find the resonant frequency of the transducer.

In addition, each of the transducers included in the ultrasonic device has its own resonant frequency, and more effective ultrasonic treatment is possible only when the ultrasonic vibrator matches the changing resonant frequency and the oscillation frequency to maintain a constant ultrasonic output.

However, the present application may be implemented in various different forms and is not limited to the embodiments described herein. In addition, in the drawings, parts not related to the description are omitted in order to clearly describe the present application, and similar reference numerals are attached to similar parts throughout the specification.

We scan the frequency to land the resonant frequency of the transducer included in the ultrasonic treatment device, and track the change in the resonant frequency of the transducer detected by scanning into heat or change in impedance over time during operation, and optimize the You can keep the resonant frequency.

1 is a first operation flow chart of a control method for controlling a resonance frequency of an ultrasonic treatment device according to an embodiment of the present application.

In step S110, the ultrasound therapy apparatus resonant frequency control system 1 may start the tuning step and the tracking step based on the operation signal of the output mode provided from the foot switch. For example, tuning is to scan the frequency to find the resonant frequency of a transducer, and tracking is when the resonant frequency of the transducer detected by scanning heats up over time during operation. In order to maintain the optimum resonant frequency by tracking the change in real time due to the change in or impedance. Ultrasound therapy resonant frequency control system (1) A tuning step and tracking step based on the start signal of the ultrasonic treatment device (ultrasound probe), not the operation of a separate switch to perform the tuning and tracking steps, but a switch to start the ultrasound treatment Can start.

In step S120, the ultrasound therapy device resonance frequency control system 1 may perform a tuning process for scanning a frequency to find a resonance frequency of a transducer included in the ultrasound therapy device. Tuning starts from the first frequency (for example, 30KHz) and increases by a preset frequency value (for example, 4Hz) to the second frequency (for example, 32KHz) through DDS (Direct Digital Synthesizer). It can be variable. At this time, the ultrasound therapy apparatus resonant frequency control system 1 may determine a frequency at which the maximum voltage is induced as the resonant frequency by monitoring a voltage input through the feedback circuit. For example, an ultrasonic vibrator generates ultrasonic waves by a resonant frequency. The function of the ultrasonic treatment device can be improved by maintaining the ultrasonic output constant by matching the resonant frequency and the oscillation frequency at which the ultrasonic vibrator changes.

In step S130, the ultrasound therapy apparatus resonant frequency control system 1 may perform a tracking process such that the resonant frequency of the transducer detected by scanning maintains a predetermined (optimal) resonant frequency. Tracking may be performed by monitoring a voltage input through a feedback circuit every preset time (eg, 100 to 200 ms), comparing it with a voltage detected during tuning, and adjusting a frequency according to the difference to compensate. At this time, the ultrasonic treatment apparatus resonance frequency control system 1 may decrease the frequency when the voltage decreases, and increase the frequency when the voltage increases. As an example, the ultrasound therapy device resonance frequency control system 1 may predict a resonance frequency within a specific frequency range of a transducer of an ultrasound therapy device (ultrasonic probe).

As an example, the ultrasonic treatment device resonant frequency control system 1 maintains the optimal resonant frequency through automatic scanning, so that heat generation or change in impedance occurs when the ultrasonic treatment device (ultrasonic transducer) is operated for a long time. As a result, the changing ultrasound output can be corrected, and stability of ultrasound applied to the patient's body can be secured. The ultrasonic therapy resonant frequency control system 1 secures stability and maintains accurate ultrasonic energy output, thereby improving reliability, and minimizing the potential impact of ultrasonic waves on the human body.

In step S140, the ultrasound treatment apparatus resonance frequency control system 1 may compare the frequency of the maximum voltage and the current frequency. For example, the ultrasound therapy apparatus resonance frequency control system 1 may detect a maximum voltage and detect a frequency at the maximum voltage. In addition, the ultrasonic treatment device resonance frequency control system 1 may detect a frequency currently occurring in the transducer of the ultrasonic treatment device (ultrasonic probe).

In step S150, the ultrasound treatment apparatus resonance frequency control system 1 may determine whether the maximum voltage frequency is included in a preset range. Here, the maximum voltage frequency may be a resonance frequency. In this case, when the maximum voltage frequency is included in a preset range, the ultrasound therapy apparatus resonant frequency control system 1 may be fed back to step S130 to perform a tracking process. On the other hand, when the maximum voltage frequency is not included in the preset range, the ultrasound treatment apparatus resonant frequency control system 1 may be fed back to step S120 to perform the tuning process again. In other words, when the result of comparing the frequency of the maximum voltage and the current frequency is not included in a preset range, the ultrasound treatment apparatus resonance frequency control system 1 may generate a feedback signal for re-performing the tuning step.

According to an embodiment of the present application, after the tracking step, the ultrasound treatment apparatus resonant frequency control system 1 performs a re-tuning step of re-scanning the frequency to find the resonance frequency of the transducer included in the ultrasound treatment device based on the feedback signal. It may contain more. For example, the ultrasound therapy resonant frequency control system 1 does not perform tuning through a separate switch operation directly from the user's input, but after the tracking step, based on the feedback signal, of the transducer included in the ultrasound therapy unit. To find the resonant frequency, retuning can be performed by rescanning the frequency.

In step S160, the ultrasound therapy apparatus resonant frequency control system 1 may end the tuning step and the tracking step based on the operation signal of the output mode provided from the foot switch. In addition, the ultrasound therapy apparatus resonance frequency control system 1 may end the tuning step and the tracking step based on the power supply signal.

Steps S110 to S160 described above are divided to explain each process, but the ultrasonic treatment device resonance frequency control system 1 of the present application allows the user (doctor) to perform the operation of the ultrasonic treatment device (ultrasonic probe) for ultrasonic treatment. After that, it is possible to track while tuning within a predetermined time (eg, 1 second) at the same time as starting (start) without a separate tuning procedure.

2 is a second operation flow chart of a control method for controlling the resonance frequency of the ultrasonic treatment device according to an embodiment of the present application. A more specific embodiment of a control method for controlling the resonance frequency of the ultrasonic treatment device described in FIG. 1 will be described with reference to FIG. 2.

In step S101, the ultrasound treatment apparatus resonance frequency control system 1 may obtain an ultrasound output operation signal from the foot switch 4. The ultrasound therapy apparatus resonant frequency control system 1 may start a tuning step and a tracking step based on an operation signal of an output mode provided from the foot switch 4. In addition, the ultrasound treatment apparatus resonance frequency control system 1 may start the tuning and tracking steps based on the input signal of the start button included in the handpiece 20. Here, the handpiece 20 may be an ultrasonic treatment device, and the ultrasonic treatment device may be a device that generates ultrasonic waves by contacting a part of the patient's body.

In step S102, the ultrasound treatment apparatus resonance frequency control system 1 may perform an HP EEPROM READ process. The ultrasound treatment apparatus resonance frequency control system 1 may perform a data READ request to the EEPROM 23 included in the handpiece 20.

In step S103, the ultrasound treatment apparatus resonance frequency control system 1 may determine the type of the affected area to be treated. In addition, the ultrasound therapy device resonance frequency control system 1 may determine the type of the affected area to be treated based on the usage of the ultrasound therapy device (ultrasonic probe). As an example, the type of the affected area to be treated may be determined as at least one of a face or a body.

In addition, the ultrasound treatment apparatus resonance frequency control system 1 may change the frequency based on the determined type of the affected area. For example, when the determined type of the affected part is a face, the frequency may be varied based on step S104. In addition, when the determined type of the affected part is body, the frequency may be varied based on step S105.

In step S104, when the determined type of the affected part is the first type (for example, the face (Fcae)), the ultrasound treatment apparatus resonant frequency control system 1 starts at the first frequency (for example, 30 KHz) in advance. The frequency may be varied up to the second frequency (eg, 32 KHz) by gradually increasing by a set frequency value (eg, 4 Hz).

In step S105, the ultrasound treatment apparatus resonance frequency control system 1 starts from a third frequency signal (eg, 36KHz) when the type of the affected part of the treatment target is a second type (eg, body). The frequency may be varied up to the fourth frequency (eg, 38 KHz) by gradually increasing by a preset frequency value (eg, 4 Hz).

The ultrasonic treatment device resonance frequency control system (1) checks the output by stepwise increasing by a preset frequency value (for example, 4 Hz) based on the determined type of the affected part, and the most optimal output frequency of the ultrasonic treatment device (ultrasonic probe) Can be obtained. Even if the same element is included in the ultrasonic treatment device (ultrasonic probe), since each transducer has its own resonance frequency, the ultrasonic treatment device resonance frequency control system (1) increases the frequency step by step by a preset frequency value to provide the optimal resonance frequency. Can be detected.

In step S106, the ultrasound therapy apparatus resonance frequency control system 1 may detect and store the maximum voltage. As an example, the value of the maximum voltage generated by the ultrasound treatment device (ultrasonic probe, handpiece 20) may be 1.0V to 2.0V, but is not limited thereto. The ultrasonic treatment apparatus resonance frequency control system 1 may supply power by user's selection and generate and supply a certain voltage. The ultrasound therapy apparatus resonance frequency control system 1 may store the detected maximum voltage in an external server, but is not limited thereto. As an example, the value of the maximum voltage may vary depending on a combination of two types of handpieces and five types of probes, but may be between about 1.0V and 2.0V. In other words, since the ultrasound therapy device resonance frequency control system 1 generates different voltage values according to the type of ultrasound therapy device, the maximum voltage value of the ultrasound therapy device (ultrasound probe) may be detected. For example, the ultrasound therapy apparatus resonance frequency control system 1 may detect a maximum voltage value of 1.0V for the first ultrasound therapy apparatus.

In step S107, the ultrasound treatment apparatus resonance frequency control system 1 may detect and store a frequency at the detected maximum voltage. As an example, the ultrasound treatment apparatus resonance frequency control system 1 may detect the frequency at the maximum voltage detected in step S106 above. The ultrasonic treatment device resonance frequency control system 1 may detect a frequency generated by a transducer of an ultrasonic treatment device (ultrasonic probe). An ultrasonic transducer is a device that converts some form of energy received from one or more sources into another form, and in the present invention, it is possible to convert electrical energy into ultrasonic waves. The ultrasonic therapy device resonance frequency control system 1 may store the frequency at the detected maximum voltage in an external server, but is not limited thereto.

In step S108, the ultrasonic treatment apparatus resonance frequency control system 1 may set the frequency of the detected maximum voltage as the resonance frequency. The ultrasound therapy apparatus resonance frequency control system 1 may derive the frequency of the maximum voltage detected in step S107 as the resonance frequency. In other words, the ultrasonic therapy resonant frequency control system 1 sets a DDS (Direct Digital Synthesizer) as the detected frequency, outputs the frequency of the maximum voltage as a square wave, and can be changed to a desired frequency in real time.

Steps S101 to S108 may be included in the tuning step S120 described above.

In step S201, the ultrasound treatment apparatus resonance frequency control system 1 may determine the tracking time. As an example, the ultrasound treatment apparatus resonance frequency control system 1 may check (detect) the tracking time every preset time (eg, 0.2 seconds). If tracking is performed frequently, the response to the load change is quick, but a problem in which the frequency is frequently changed may occur, so the ultrasound therapy apparatus resonant frequency control system 1 may periodically perform tracking at a preset time.

In step S202, the ultrasound treatment device resonance frequency control system 1 may compare the current voltage and the maximum voltage provided to the ultrasound treatment device. In other words, the ultrasonic treatment device resonance frequency control system 1 may detect a current voltage provided to the ultrasonic treatment device (ultrasonic probe), and compare the current voltage and X% (a percentage) of the maximum voltage. The ultrasonic treatment device resonance frequency control system 1 may detect a current voltage provided to the ultrasonic treatment device (ultrasonic probe). The ultrasound therapy apparatus resonance frequency control system 1 may compare the detected current voltage with the maximum voltage detected in step S106. For example, the ultrasonic treatment device resonance frequency control system 1 may detect a maximum voltage value of 1.0V for the first ultrasonic treatment device. The ultrasonic treatment device resonance frequency control system 1 may detect a current voltage provided to the first ultrasonic treatment device. When the current voltage provided to the first ultrasonic treatment device is detected as 1.5V, the ultrasonic treatment device resonance frequency control system 1 may compare the detected current voltage with X% (a percentage) of the maximum voltage.

In step S203, the ultrasonic treatment device resonance frequency control system 1 may control the frequency of the ultrasonic treatment device based on the result compared in step S202. As an example, the ultrasound therapy apparatus resonance frequency control system 1 may generate a control signal for controlling the frequency when the current voltage is large as a result of comparing the current voltage and the maximum voltage. As another example, the ultrasound treatment apparatus resonance frequency control system 1 may generate a control signal for reducing the frequency when the current voltage is small as a result of comparing the current voltage and the maximum voltage. As another example, the ultrasound treatment apparatus resonance frequency control system 1 may generate a control signal to maintain the current frequency when the current voltage and the maximum voltage are the same as a result of comparing the current voltage and the maximum voltage.

In step S204, the ultrasound treatment apparatus resonance frequency control system 1 may compare the frequency of the maximum voltage and the current frequency. Here, the frequency of the maximum voltage may be a resonance frequency. The ultrasonic treatment device resonance frequency control system 1 may compare the frequency of the maximum voltage and the frequency generated by the transducer of the current ultrasonic treatment device (ultrasonic probe). In other words, the ultrasound therapy device resonance frequency control system 1 may compare the resonance frequency with the frequency generated by the transducer of the current ultrasound therapy device (ultrasonic probe).

In step S205, the ultrasound treatment apparatus resonance frequency control system 1 may determine whether the frequency of the maximum voltage and the current frequency are compared within a preset range based on the frequency of the maximum voltage. In other words, the ultrasound treatment apparatus resonance frequency control system 1 may determine whether the resonance frequency is included in a preset range (eg, ±100 Hz) based on the resonance frequency as a result of comparing the resonance frequency and the current frequency. Here, the maximum voltage frequency (assumed as a resonance frequency) differs depending on a combination of two handpieces and five probes, but can be divided into approximately a 29.9 kHz to 30.5 kHz section and a 37 kHz to 38 kHz section. For example, in step S205, when the maximum voltage frequency is 37 kHz, the ultrasound therapy apparatus resonant frequency control system 1 may determine whether a result of comparing the maximum voltage frequency and the current frequency is included in 36.900 Hz to 37.100 Hz. .

In this case, based on the determination result of step S205, the ultrasound therapy apparatus resonant frequency control system 1 may provide feedback to a tuning step or a tracking step. In other words, the ultrasound therapy apparatus resonant frequency control system 1 may generate a feedback signal for feedback (reperform) in the tuning step or the tracking step. For example, when the comparison result of the frequency of the maximum voltage and the current frequency is not included in the preset range, the ultrasound treatment apparatus resonance frequency control system 1 may be fed back to the step of determining the type of the affected area to be treated. For example, when the maximum voltage frequency is 37 KHz and the current frequency is 37.500 Hz, the ultrasound therapy resonant frequency control system 1 is not included in 36.900 Hz to 37.100 Hz, so it can be fed back to the tuning step. In other words, when the ultrasound therapy apparatus resonant frequency control system 1 is not included within a preset range based on the frequency of the maximum voltage as a result of comparing the frequency of the maximum voltage and the current frequency, it may feed back to step S103.

In addition, the ultrasound treatment apparatus resonance frequency control system 1 may be fed back to the step of detecting a tracking time when the comparison result of the frequency of the maximum voltage and the current frequency is included in a preset range. For example, when the comparison result of the frequency of the maximum voltage and the current frequency is included in a preset range, the ultrasound therapy resonant frequency control system 1 may be fed back to the step S201 of determining a tracking time. For example, when the maximum voltage frequency is 37 KHz and the current frequency is 35 Khz, the ultrasound therapy resonant frequency control system 1 is included in 36.900 Hz to 37.100 Hz, so it can be fed back to the tracking step. In other words, when the ultrasound therapy apparatus resonant frequency control system 1 is within a preset range based on the frequency of the maximum voltage as a result of comparing the frequency of the maximum voltage and the current frequency, it may feed back to step S201.

In other words, when the result of comparing the frequency of the maximum voltage and the current frequency is not included in a preset range, the ultrasound treatment apparatus resonance frequency control system 1 may generate a feedback signal for re-performing the tuning step. On the other hand, when the result of comparing the frequency of the maximum voltage and the current frequency is not included in a preset range, the ultrasound treatment apparatus resonant frequency control system 1 may generate a feedback signal for re-performing the tracking step.

Steps S201 to S205 may be included in the tracking step S130 described above.

In the above description, steps S110 to S150 and steps S101 to S205 may be further divided into additional steps or may be combined into fewer steps, depending on the embodiment of the present application. In addition, some steps may be omitted as necessary, and the order between steps may be changed.

As an example, an 8MHz crystal oscillator may be used as the system clock of the ultrasonic treatment device resonance frequency control system 1.

In addition, when the comparison result of the frequency of the maximum voltage and the current frequency is not included in a preset range, the control unit 10 may generate a feedback signal for re-performing the tuning step. In addition, when the comparison result of the frequency of the maximum voltage and the current frequency is included in a preset range, the controller 10 may generate a feedback signal for re-performing the tracking step.

The frequency synthesizer 11 may tune and track a frequency supplied to a transducer in real time under the control of the control unit 10 (MCU) and change it. The frequency synthesizer 11 can output a sine wave, a triangle wave, and a square wave up to 16 MHz with 0.06 Hz resolution using AD9837, a programmable waveform generator.

In addition, the frequency synthesizer 11 monitors the voltage input through the feedback circuit every preset time, compares it with the voltage detected during tuning, and adjusts the frequency according to the difference to correct the voltage. For example, the frequency synthesizer 11 monitors the voltage input through the feedback circuit every 100 ms to 200 ms, compares it with the voltage detected during tuning, and adjusts the frequency according to the difference to correct it. The frequency synthesizer 11 may provide the control unit 10 to decrease the frequency when the voltage decreases and increase the frequency when the voltage increases.
