The computing elements process data by reading and executing program instructions stored in the storage unit 320. The storage 320 may be, for example, one or a combination of large-capacity storage such as hard disk, SSD, and network storage, non-volatile memory such as flash memory, and volatile memory such as RAM. have.

According to an aspect, the storage unit 320 stores treatment guide information including operation guide content for each treatment part and information on a risk area for each treatment part. In one embodiment, the treatment site is determined according to acupuncture points. When the operator selects acupuncture points, the corresponding treatment site is selected. Acupuncture points are defined in the field of oriental medicine. Accurately performing acupuncture points requires a lot of experience and anatomical knowledge. According to an aspect, the manipulation guide content is prepared as a database having a tree structure for each major and sub-category of acupuncture points. In one embodiment, the manipulation guide content includes document information describing the acupuncture method of the acupuncture point, 2D or 3D image information showing the anatomical structure of the acupuncture point, and a graphic animation or video showing the acupuncture procedure at the point of the point. Include. The document information may include a brief description of a corresponding acupuncture point, information on a patient's posture and a region where the probe is to be placed, and a specific method of accurately finding the treatment region using ultrasound.

According to an additional aspect, procedure guide information may be stored in the storage unit 320. The procedure guide information includes risk area information for each treatment site. The risk area information may be, for example, an image pattern or feature information capable of distinguishing a specific biological tissue, such as a blood vessel, in an ultrasound image. In general, it is known that ultrasound images have a limitation in resolution, so it is not easy to recognize a specific biological tissue in the image. Since acupuncture points for acupuncture are limited to a very narrow location, the location of the treatment can be specified. Although the biological tissues are slightly different for each person, the risk area in the ultrasound image is determined from information on the pattern or feature of the image of the biological tissue commonly seen in ultrasound images, for example, the characteristics of the luminance distribution or the shape of the boundary line. Recognition can increase accuracy and likelihood of success.

As another example, the risk area information may be 3D area information of a living tissue. The standard 3D area information of a living tissue indicates the shape of the corresponding biological tissue, and the overall 3D area information may be a map for finding a corresponding living tissue in an ultrasound image.

The ultrasonic signal processor 370 generates an image by processing an ultrasonic signal obtained by driving an ultrasonic element array. The imaging modes of the ultrasound imaging apparatus include B mode, M mode, D mode using Doppler effect, and C mode. The ultrasonic signal processing unit 370 drives the ultrasonic element array 250 in one of these modes to generate ultrasonic image information from an output signal.

The user interface unit 390 receives a user's operation command through an operation unit such as a mouse, a touch pad, and a keyboard, and outputs an ultrasound image or information generated by the system as visual information through a screen or as audio information through a speaker. do. According to an aspect, the user interface unit 390 includes an instruction information providing unit 391. The guide information providing unit 391 extracts and provides a corresponding operation guide content from the storage unit 320 by selecting a site for acupuncture points from a practitioner. According to an aspect, the user selects one of the major categories through, for example, a touch input, and then selects one of the sub-categories to select a acupuncture point treatment site. The user interface unit 390 extracts the operation guide content of the acupuncture points selected from the database. Document information explaining the acupuncture method of the selected acupuncture points, 2D or 3D image information showing the anatomical structure of the corresponding acupuncture points, and graphic animations or videos showing the acupuncture procedure at the corresponding acupuncture points are provided according to the user's selection.

According to an additional aspect, the user interface unit 390 may further include a display setting unit 393 for each portion. In this case, the procedure guide information may further include setting parameters for each treatment site. The display setting unit 393 for each region extracts the setting parameter for each treatment region from the storage unit 320 and sets the display control parameter of the ultrasound image accordingly. By setting parameters related to the ultrasound scan depth, zooming magnification, and selection of the display range as standard values for each treatment area, the size and range of the displayed image can be limited. Accordingly, an actual image that is closer in size and range to the ultrasound image assuming the dangerous area information may be obtained, and the speed or precision of image recognition may be improved.

The needle position detection unit 330 calculates the position of the needle from inputs of at least two sensors. U.S. Patent No. 9,597,008, issued to EZONO AG as of March 21, 2017, uses a plurality of magneto-metric detectors to measure the strength of the magnetic field of a magnetized needle and use it to position the needle. Disclosing a technique for measuring The needle positioning system of EZONO AG is commercially available and provided, and the applicants are using this technology in developing the proposed invention in cooperation with EZONO AG. EZONO AG's magnetic positioning system uses a plurality of magnetic positioning detection elements built into the probe, and can calculate the position of the needle and output it by superimposing it on an ultrasound image. However, the proposed invention is not limited thereto, and various known positioning techniques, such as an RF method, a method using an anchor, and a positioning system using a radio fingerprint, may be applied.

In one embodiment, the probe 10 includes an acceleration sensor 230, for example a gyro sensor. The probe position detection unit 350 measures the position and posture of the probe, that is, an inclined direction, from the output of the acceleration sensor 230. The needle position detection unit 330 first calculates the position of the needle 30 in the reference coordinate system of the probe 10 from the output of the magnetic positioning detection elements 210. Thereafter, the needle position detection unit 330 calculates the position of the needle 30 in the absolute coordinate system by converting the coordinate system using the position and posture information of the probe detected by the probe position detection unit 350.

The treatment risk warning unit 310 determines a three-dimensional risk area from information on the risk area corresponding to the selected treatment area and the ultrasound image generated by the ultrasound signal processing unit, and determines the position of the needle calculated by the acupuncture position detection unit 330. A warning signal is output when the position of the tip of the following needle approaches the danger area. In one embodiment, the treatment risk warning unit 310 includes a risk area recognition unit 313 and a risk determination unit 311. The risk area recognition unit 313 recognizes a 3D risk area from an ultrasound image using the risk area information.

In one embodiment, the risk area information is image pattern or feature information of a specific biological tissue. The 3D modeling of a blood vessel existing in a risk area, for example, a specific acupuncture point, and image patterns generally appearing when each modeling is viewed on an ultrasound image may be the risk area information. As another example, a pattern value capable of determining a blood vessel region by comparing the function value with a reference value when a specific correlation function between blocks, for example, 16*16 pixel blocks and blocks of the corresponding size of the actual ultrasound image is calculated. This could be the danger zone information.

In one embodiment, the risk area recognition unit 313 first stores a plurality of images obtained by scanning the acupuncture points in which the probe 10 is selected, and obtains 3D information around the acupuncture points from the plurality of images. This 3D information has not been modeled as a 3D volume image. In this input collection of ultrasound images, a 3D risk area is recognized using an image pattern of the risk area information. In this embodiment, the 3D image is zoomed and shifted so as to have the same scale and position compared with the dangerous 3D dangerous area modeling information stored through recognition of the feature points of the 3D image acquired first. Subsequently, the converted 3D ultrasound image is divided into blocks. Thereafter, a correlation function is calculated for the pattern around the corresponding position of the dangerous area included in the dangerous area information and the block of the ultrasound image to find 3D modeling from the ultrasound image. The 3D risk area modeling information may be obtained from the collection of ultrasound images obtained by repeating this process and matched with the ultrasound image.

Since acupuncture points for acupuncture are limited to a very narrow location, the location of the treatment can be specified. Although the biological tissues are slightly different for each person, the risk area in the ultrasound image is determined from information on the pattern or feature of the image of the biological tissue commonly seen in ultrasound images, for example, the characteristics of the luminance distribution or the shape of the boundary line. Recognition can increase accuracy and likelihood of success.

The risk determination unit 311 calculates how close the position of the tip of the needle calculated by the acupuncture position detection unit 330 is to the 3D risk area modeling area in the living tissue of the person to be treated recognized by the risk area recognition unit 313, A warning message is generated and output when a certain distance or more or the direction in which the tip of the needle is moving is toward the danger area and the moving speed is more than a certain level. The warning message may be output on screen and/or audio.

According to one aspect, the absolute position of the needle position is calculated by an independent system separate from the ultrasound image. In addition, the 3D modeling information of the dangerous area is calculated from an ultrasound volume image and then stored. Accordingly, since the treatment risk warning unit 310 compares the position of the tip of the needle with the 3D modeling area information of the risk area, the stored position of the tip of the needle is generated by the ultrasonic signal processor 370 and output to the screen. Even out of the video range, a warning can be output when approaching a danger area.

According to another aspect, the needle position detection unit 330 may include a sensor-based position calculation unit 331, an image-based position calculation unit 333, and a position information output unit 335. 4 is a block diagram showing the configuration of a needle position detection unit according to another embodiment. The sensor-based position calculation unit 331 calculates the position of the needle from at least two sensor inputs. This is as described above.

The image-based position calculator 333 estimates the position of the needle by tracking the movement of the tissue in the ultrasound image. It is advantageous to use other methods in parallel, because the danger zone entry may be made at the moment the magnetic positioning system is not operating. The saliva is so thin that it is not visible on the ultrasound image.

According to an aspect, the image-based position calculator 333 continuously compares the generated ultrasound images to identify a changing region and a non-changing region, and calculates a region that changes in a specific direction as a needle position. For example, by calculating the amount of change between image frames, a motion vector can be obtained, and accordingly, a motion of a biological tissue can be identified. When the needle enters the living tissue, the surrounding living tissue is pushed out, causing movement. This amount of change can reflect movement relatively well even when the image quality is poor. By analyzing the direction of movement of the living tissue, the position of the tip of the needle can be estimated.

In another embodiment, the ultrasonic signal processing unit 370 drives the ultrasonic element array in a Doppler mode, detects the velocity of the biological tissue pushed out when the needle enters, identifies the biological tissue, and estimates the position of the needle therefrom. I can. Compared to luminance mode, Doppler mode can sensitively identify moving tissue. While driving in the Doppler mode, the motion of the biological tissue can be obtained through the difference between the frames of the ultrasound image, and the needle position can be estimated by finding a part with large motion or a central axis of motion from the distribution of motion.

The location information output unit 335 calculates the position of a needle by synthesizing the outputs of the sensor-based location calculation unit 331 and the image-based location calculation unit 333. The location information output unit 335 preferentially selects the output of the sensor-based location calculation unit 331, but if it is determined that there is no output or is not reliable, the image-based location calculation unit 333 is executed in parallel. Select output. The reliability of the result of calculating the needle position can be determined to be unreliable, for example, when the continuity of the movement of the tip of the needle is greatly broken. As another example, the location information output unit 335 preferentially selects the output of the sensor-based location calculation unit 331, but when it is determined that the output does not exist or is unreliable, the image-based location calculation unit ( 333) Create a location by combining it with the output of the task.

In FIG. 3, the image display control unit 360 combines the ultrasound image generated by the ultrasound signal processing unit 370, the guide information provided by the user interface unit 390, and the position of the needle detected by the needle position detection unit 330. To indicate. For example, the image display control unit 360 overlays and displays a needle image generated as a graphic reflecting the position of the needle detected by the needle position detection unit 330 on the ultrasonic image generated by the ultrasonic signal processing unit 370. I can. As another example, the image display controller 360 may simultaneously display the instruction information provided by the user interface unit 390 on the ultrasound image generated by the ultrasound signal processing unit 370 by dividing the screen.

5 is a block diagram showing the configuration of a procedure risk warning unit according to another embodiment. As shown, the risk area recognition unit 313 of the procedure risk warning unit 310 according to another embodiment may include a reflection coefficient image analysis unit 315 and a Doppler image analysis unit 317. The reflection coefficient image analyzer 315 drives the ultrasonic signal processor 370 in a luminance mode or a B mode (brightness mode) to generate an image by processing a reflection coefficient of an ultrasonic signal to recognize a dangerous area. The specific operation of the reflection coefficient image analysis unit 315 is similar to the operation of the above-described danger area recognition unit 313. The Doppler image analysis unit 317 drives the ultrasound signal processing unit 370 in a Doppler mode to generate an image by driving an ultrasound signal in a Doppler mode, or a D mode (Doppler mode) or a C mode (color Doppler mode) to detect a dangerous area. Recognize. When driven in the Doppler mode, it is advantageous to recognize a region with a flow such as a blood vessel. By comparing the shape of the flow area with the stored risk area information, modeling of the risk area in the living body tissue of the subject can be generated.

According to an additional aspect, the Doppler image analyzer 317 may intermittently drive the ultrasound signal processor 370 in the Doppler mode in the background while imaging the ultrasound signal processor 370 in the luminance mode. By using both the luminance mode image and the Doppler mode image, the recognition of the risk area is more reliable, and the position change of the tissue due to the movement of the needle can be detected to improve the needle position tracking.
