Description

Organ recognition and treatment system using ultrasound

The present invention relates to an organ recognition and treatment system using ultrasound, and more particularly, to an organ recognition and treatment system using ultrasound, in which a practitioner recognizes the type, location, and condition of a patient's organ using ultrasound and simultaneously treats the organ to be treated. It is about organ recognition and treatment systems.

High-Intensity focused ultrasound (HIFU) treatment is a non-invasive and non-traumatic approach. This applies especially to patients with tumors. Compared to conventional surgical treatment or chemotherapy, HIFU treatment is less traumatic for patients, and therefore its application is rapidly increasing. These indications include liver cancer, bone sarcoma, breast cancer, pancreas cancer, kidney cancer, soft tissue tumor and pelvic tumor. includes In addition, treatment using low-intensity focused ultrasound (LIFU) has recently been shown as a new treatment alternative due to its new neuromodulation technology and ability to non-invasively stimulate various parts. Neuromodulation can stimulate or inhibit various nerve activities by stimulating nerve activity in a specific area, and through this stimulation method, it is used as a non-invasive treatment method.

Most focused ultrasound treatments use an ultrasound imaging device to position a target tumor in an area of interest and monitor the treatment. As a device for forming and displaying an image of , it is often expressed as a B-mode (brightness-mode) that uses the reflection coefficient of human tissue.

On the other hand, some focused ultrasound treatments use magnetic resonance imaging (MRI) for this purpose, and MRI visualizes images by obtaining information from the degree of magnetic relaxation between tissues. MRI is a diagnostic technique that uses a magnetic field to create pictures of structures in the body. It creates images based on how hydrogen atoms in the body react with magnetic fields and electromagnetic waves. Based on the above principles, MRI is the only imaging technique capable of measuring temperature in the cauterization range, and is used to detect tumors in soft tissues of the body such as the brain, spinal cord, heart, eyeball, liver, pancreas, kidney, breast and prostate and examine the disease. do.

As ultrasound image display methods such as the B-mode or MRI are unified, the conventional ultrasound imaging apparatus is vulnerable to virtual images due to organ motion or air in the intestine because ultrasound images cannot be compared.

In addition, in the conventional focused ultrasound treatment, it is necessary to accurately calculate the motion, distance, and position of the organ, and then generate ultrasound toward the treatment target, such as a tumor generated in the organ. There is a problem in that the efficiency of treatment is reduced due to difficulty in accurately calculating the motion, distance, and position of organs that are changed in real time by exercise.

In addition, the ultrasound unit 10 irradiates ultrasound of a frequency for recognition to generate and analyze an ultrasound image, and irradiates ultrasound of a frequency for treatment to a movable focus for long-term treatment. The shape may be changed as follows according to the method of irradiating the ultrasonic wave of the frequency.

2 is a block diagram schematically showing an ultrasound unit according to the present invention, and FIG. 3 is a block diagram schematically showing the structure and signal processing process of an ultrasound unit according to an embodiment of the present invention.

Referring to FIG. 2 , the ultrasound unit 10 includes an ultrasound image generation and analysis unit 11 for generating and analyzing an ultrasound image and an ultrasound treatment unit 12 for irradiating ultrasound to a movable focus. are provided

The ultrasound image generation and analysis unit 11 includes a first ultrasound probe 110 including a transducer for recognition that transmits ultrasound of the frequency for recognition to a patient in order to generate or analyze an ultrasound image.

The ultrasonic treatment unit 12 includes a second ultrasonic probe 120 including a treatment transducer for irradiating ultrasonic waves of a treatment frequency to a movable focus to treat an organ of a treatment target.

In the present invention, the ultrasound of the frequency for recognition to be irradiated to the patient by the first ultrasound probe 110 may have a frequency band of 1 MHz or higher, and the ultrasound of the frequency for treatment to be irradiated to the moving focus by the second ultrasound probe 120. may have a frequency band of 20 to 500 KHz.

At this time, if the frequency band of the ultrasonic wave for recognition emitted from the first ultrasonic probe 110 is 1 MHz or higher, the frequency band to be used for the examination of the organ to be treated through the ultrasound unit 10 is the heart (2 to 3). MHz), abdomen (3-5 MHz), breast and thyroid (7.5-13 MHz), eye (7.5-12 MHz), and gastrointestinal tract and blood vessels (15-30 MHz).

The ultrasound unit 10 allows the first ultrasound probe 110 to irradiate ultrasound of a frequency for recognition, and the second ultrasound probe 120 to irradiate ultrasound of a frequency for treatment to a movable focus, FIG. 3 As shown in, additional components are provided, which will be described in detail through the ultrasonic unit 10 of another embodiment to be described later.

Figure 4 is a block diagram schematically showing the configuration and signal processing of the ultrasound unit according to another embodiment of the present invention.

Referring to FIG. 4 , an ultrasound unit 10 according to another embodiment replaces the ultrasound image generation and analysis unit 11 and the ultrasound treatment unit 12 to emit ultrasound at a frequency for recognition and ultrasound at a frequency for treatment. An image generation and treatment unit 100 is provided.

The ultrasound image generation and treatment unit 100 includes an ultrasound probe including a transducer module in which the recognition transducer and the treatment transducer are combined to enable ultrasound image generation and ultrasound irradiation with a moving focus.

In the ultrasound probe, a plurality of (eg, 100 to 300) piezoelectric elements are divided into irradiation time zones through time division so that the ultrasound image generation and the ultrasound treatment process can be performed simultaneously. can be investigated.

Furthermore, the ultrasound probe adjusts the direction of the ultrasound by controlling the phase so that the ultrasound of the therapeutic frequency irradiated toward the organ is converged at the movable focal point.

On the other hand, the ultrasound unit 10 includes an object discrimination and detection module 13, a target processing module 14, a beam former 15, and a beam controller ( 16) and a main controller 17 are further provided, and a multiplexer (MUX), an amplifier (AMP), an A/D converter (ADC), a band pass filter (BFP), etc. are on the circuit to enable the operation of each component. can be placed.

The object discrimination and detection module 13 analyzes the ultrasound image and the ultrasound image generated by the treatment unit 100 through deep learning learning to determine an organ in the ultrasound image, and determines the organ according to the movement of the organ. detect changes in motion, distance, and position of

In the present invention, the process for the object discrimination and detection module 13 to identify organs and detect changes in the motion, distance, and position of the organs according to the movements of the organs is as follows.

5 is a flowchart schematically illustrating a process of recognizing a treatment target by a deep learning module according to the present invention.

Referring to FIG. 5 , the object discrimination and detection module 13 may be trained using a deep learning method to discriminate and detect an organ from an ultrasound image (S11).

At this time, the object discrimination and detection module 13 is not limited to a deep learning learning method, but is preferably deep learning learning through a convolutional neural network (CNN) method, and a convolutional neural network An algorithm for performing deep learning based learning may be configured.

In addition, the object discriminating and detecting module 13 is trained to discriminate an organ in an ultrasound image by repeating a convolution process and a pooling process of a convolutional neural network.

After deep learning learning, when the object discrimination and detection module 13 acquires (generates) an ultrasound image (S12), it can discriminate an organ in the ultrasound image according to a rule established through deep learning learning ( S13).

After determining the organ, the object discrimination and detection module 13 tracks the organ identified in the ultrasound image (S14), thereby determining the motion, distance, and location of the organ according to the movement of the organ caused by the patient's respiration. detect change

Referring back to FIG. 4 , the target processing module 14 predicts the motion, distance, and position of the organ through changes in the motion, distance, and position of the organ detected by the object discrimination and detection module 13.

In the present invention, the target processing module 14 determines the motion, distance and position of the organ in order to predict the motion, distance and position of the organ using non-linearized data, the amount of change in the motion, distance and position of the organ. An algorithm to which an Extended Kalman Filter and a Jacobian matrix are applied is configured to linearize the change in motion, distance, and position of the organ.

Here, the extended Kalman filter is a filter that relaxes the linearity assumption in the Kalman filter, and applies a Jacobian matrix to linearize the change in motion, distance, and position of the organ, and the Jacobian matrix is nonlinearized data. The motion, distance and position of the organ are linearized, and this process is as shown in [Equation 1] and [Equation 2] below.

[Equation 1] defines the amount of change in motion (r), distance (Φ), and position (θ) of the organ, which are nonlinear data.

[Equation 2] linearizes the changes in the motion (r), distance (Φ), and position (θ) of the organ.

The target processing module 14 uses the transformation and linearization process of the Jacobian matrix and the prediction and update process of the extended Kalman filter to determine the motion, distance, and position of the organ linearized using the motion, distance, and change amount of the organ. and predict location.

The beamformer 15 adjusts the position of the movable focus by adjusting the amplitude or delay time of a signal to be input to the ultrasound probe according to the motion, distance, and position of the organ predicted from the target processing module.

The beamformer 15 transmits a signal to the ultrasound probe so that ultrasound waves of the frequency for recognition and the frequency for treatment to be irradiated from the ultrasound probe are generated. Harmonic (or harmonic) between the frequency for recognition and the frequency for treatment this may occur.

To this end, the ultrasound unit 10 further includes a frequency adjustment module 18 to remove harmonics between the frequency for recognition and the frequency for treatment.

6 is a conceptual diagram schematically illustrating the configuration of a conventional beam former and a beam former according to the present invention.

Referring to FIG. 6, shown in (a) of FIG. 6 is a conventional beamformer, and shown in (b) of FIG. 6 is the beamformer 15 of the present invention to which the frequency adjustment module 18 is connected. .

Referring to (b) of FIG. 6, the frequency adjusting module 18 inputs the signal to the beamformer 15 to remove harmonics between a frequency for recognition and a frequency for treatment to be generated from the signal of the beamformer 15. Adjusts (modulates) the frequency of the signal to be, and may be connected to the beamformer 15 to adjust the frequency of the signal.

That is, the beamformer 15 of the present invention adjusts the amplitude or delay time of the signal whose frequency is adjusted through the frequency adjustment module 18 to remove the harmonic between the frequency for recognition and the frequency for treatment. The ultrasonic probe receives a signal from which harmonics have been removed.

Accordingly, the ultrasound image generation and treatment unit 100 irradiates ultrasound of the frequency for treatment to the mobile focus by using the primary resonant frequency of the harmonic-removed signals of the transducer module as the frequency for treatment, and Ultrasound of the frequency for recognition may be transmitted to the patient by using a resonant frequency of a second or higher order, which is relatively higher than the primary resonant frequency, as a recognition frequency. Hereinafter, a resonant frequency relatively higher than the primary resonant frequency will be set as the secondary resonant frequency and described.

In the present invention, the transducer module may have a primary resonant frequency of 250 KHz or 500 KHz. When the primary resonant frequency of the transducer module is 250 Khz, the secondary resonant frequency may be 500 to 750 KHz, When the primary resonant frequency of the transducer module is 500 KHz, the secondary resonant frequency may be 1.5 to 1.7 MHz.

On the other hand, 2.4 MHz is usually used for organ inspection ultrasound to improve resolution, which means the ability to distinguish different organs (tissues) within the human body and display them as aspects. .

However, the ultrasound unit 10 of the present invention can determine the organ and predict the motion, distance, and location through the object discrimination and detection module 13 and the target processing module 14, Since there is no need to improve the resolution through this method, there is an advantage in that a frequency lower than that of normal ultrasonic waves (up to 2 MHz or less) can be used as a frequency for recognition.

Referring back to FIG. 4 , the beam controller 16 controls the operation of the beam former 15 so that a signal is generated in the beam former 15 .

The main controller 17 controls the operation of the beam controller 16 so that the ultrasound probe emits ultrasound waves of a frequency for recognition and/or a frequency for treatment.

To describe the operation process of the ultrasound unit 10 in detail with reference to FIG. 4 , when the beamformer 15 transmits a signal to the ultrasound probe of the ultrasound image generation and treatment unit 100, the ultrasound probe Ultrasound of a second resonant frequency, which is a frequency for recognition, is transmitted to the patient, and the amplifier and A/D converter of the ultrasound unit 10 reflect it from the patient and amplify and A/D convert it, and then the beamformer 15 After generating an ultrasound image through the ultrasound received from the beamformer 15, the object discrimination and detection module 13 determines an organ in the ultrasound image and determines the motion, distance, and position of the organ. and if the target processing module 14 predicts the motion, distance, and position of the organ through the amount of change in the motion, distance, and position of the organ according to the motion of the organ, the beamformer 15 and the frequency adjustment After the module 18 adjusts the frequency of the signal and the amplitude or delay time of the signal, the signal is transmitted to the ultrasound probe to adjust the movable focus, and the ultrasound probe has a primary resonant frequency, which is a frequency for treatment. Ultrasound is irradiated to a mobile focus to allow long-term treatment.

Furthermore, the bandpass filter of the ultrasound unit 10 may be matched with the frequency band of ultrasound, and the multiplexer may be switched to transmit or receive ultrasound according to the process of transmitting and receiving ultrasound.

Referring back to FIG. 2 , the information processing unit 20 processes the ultrasound image received from the ultrasound unit 10 according to the display and analysis mode set through the input unit 40, and converts the processed ultrasound image into the It is transmitted to the display unit 30.

The display unit 30 outputs the ultrasound image processed by the information processing unit 20, and the operator recognizes the patient's organ condition using the ultrasound image output through the display unit 30.

However, in order to reduce the cost of the organ recognition and treatment system 1 using ultrasound, the display unit 30 may be omitted from the components of the organ recognition and treatment system 1 using ultrasound.

In this way, when the process of outputting the ultrasound image is omitted, the information processing unit 20 transmits the ultrasound image processed by the method of the display and analysis mode of the input unit 40 to the ultrasound unit 10 instead of the display 30. The ultrasound unit 10 analyzes the ultrasound image learned through deep learning and processed by the information processing unit 20, determines the organ through the analysis of the ultrasound image, and among the identified organs Ultrasound is irradiated to the organ of the target to be treated so that the treatment of the organ proceeds.

The input unit 40 is provided with an input means for displaying an ultrasound image and setting an analysis mode, and a signal may be input to the input means by an operator.

In the present invention, the display and analysis modes of the ultrasound image set through the input unit 40 refer to M-mode (motion mode), B-mode (brightness mode), and D-mode, which are methods of processing the ultrasound image. A Doppler mode may be included.

The M-mode is a method of displaying the distance of a moving reflector as a temporal change, and is mainly used to observe a heart valve, and has a feature of being able to record a heart sound of a fetus.

The B-mode is a method of representing reflected sound as bright dots, which is represented as a two-dimensional cross-sectional image, and outputs a real-time ultrasound image when actuated by phase difference using an electronic actuation method of a piezoelectric element.

The D-mode uses a pulse wave or a continuous wave as a method of measuring and displaying the speed and direction of blood flow using the Doppler effect.

That is, the input unit 40 can set the display and analysis mode of the ultrasound image to at least one of the M-mode, B-mode, and D-mode, but may also set all display and analysis modes of the ultrasound image. there is.

Accordingly, when the display unit 30 is provided in the organ recognition and treatment system 1 using ultrasonic waves, the display unit 30 is configured in the M-mode, according to the setting of the display and analysis mode in the input unit 40, At least one ultrasound image of B-mode and D-mode as well as ultrasound images of M-mode, B-mode, and D-mode may be output.

As a specific example, when M-mode, B-mode, and D-mode are set as ultrasound image display modes in the input unit 40, the display unit 30 displays and names analysis modes so that the operator can distinguish them. In the form described above, M-mode, B-mode, and D-mode ultrasound images can be output to the output area.

As another specific example, when the M-mode, B-mode, and D-mode are set as ultrasound image display and analysis modes in the input unit 40, the display unit 30 allows the operator to display ultrasound in a specific display and analysis mode. The ultrasound images of M-mode, B-mode, and D-mode are sequentially output to the output area so that the image can be selected, and the ultrasound image of the display mode selected by the operator inputting a signal is output on the output area. and ultrasound images in the remaining display modes may be canceled so as not to be exposed on the output area.

Unlike this, when the display unit 30 is not provided in the organ recognition and treatment system 1 using ultrasonic waves, the ultrasound unit 10 has an M-mode set through the display and analysis mode of the input unit 40, The ultrasound image generated by at least one of the B-mode and the D-mode is received from the information processing unit 20 and then analyzed to determine the organ, and the motion, distance, and position of the organ to be treated among the identified organs are determined. By irradiating ultrasonic waves to the movable focus that changes according to the change, the organ of the treatment target can be treated.

Referring back to FIG. 1 , the organ recognition and treatment system 1 using ultrasound may further include an alarm unit 50 that generates an alarm in order to guide an operator on the process of generating an ultrasound image and the end of the long-term treatment process. there is.

The alarm unit 50 generates a first alarm so that an operator can determine the end of an ultrasound image generation process by transmitting ultrasound of a frequency for recognition to the patient, and transmits ultrasound of a frequency for treatment to a mobile focus. A second alarm different from the first alarm may be generated so that the operator can determine the end of the long-term treatment process irradiated on the body.

By generating the first and second alarms, the alarm unit 50 can minimize the waiting time of the patient after generation of an ultrasound image or long-term treatment.

Such an organ recognition and treatment system 1 using ultrasound is attached to a conventional hospital bed or equipped with a multi-joint position control device for fixing the patient's position so that it can be applied to a lying or face-down patient. can be attached to

Also, in the organ recognition and treatment system 1 using ultrasound, the ultrasound unit 10 may be transformed into a belly band so that it can be used at home at home.

Hereinafter, an organ recognition and treatment method (S100) for recognizing a patient's organ state and treating a target organ using the ultrasound-based organ recognition and treatment system 1 will be described in detail.

7 is a flowchart schematically illustrating a treatment process using an organ recognition and treatment system using ultrasound according to the present invention.

At this time, if the organ recognition and treatment system 1 using ultrasound is operated in an automated mode, the ultrasound unit 10 is automatically operated and transmits ultrasound at a frequency for recognition to the patient, and then the object discrimination and An organ may be discriminated and sensed from the ultrasound image generated by the sensing module 13 (S130).

In contrast, if the organ recognition and treatment system 1 using ultrasound is operated in a manual mode, the operator manually (directly) manipulates the transducer module to generate an ultrasound image through ultrasound at a frequency for recognition, The focus is aimed so that the ultrasound of the frequency for treatment is irradiated to the organ (S160).

After determining and detecting the organ, the operator may select whether to automatically set a method of irradiating ultrasound to the movable focus or manually (S140).

At this time, if the operator automatically sets the ultrasound irradiation method (S140-YES), the ultrasound unit 10 adjusts the location of the movable focus of the beamformer 15, and then the ultrasound probe adjusts the frequency for treatment. Ultrasound of the movable focus is irradiated so that the patient's organs are treated (S150).

In contrast, if the operator manually sets the ultrasound irradiation method (S140-NO), the operator manually manipulates the transducer module to aim the focus so that the ultrasound of the frequency for treatment is irradiated to the organ (S160), The patient's organs are treated by irradiating ultrasound of the desired frequency (S170).
