Description

  The present invention relates to an ultrasonic diagnostic apparatus having a display function for facilitating visual recognition of a puncture needle position when a treatment site is monitored using a three-dimensional image in puncture treatment.

  An ultrasonic diagnostic apparatus is a medical imaging device that non-invasively obtains a tomographic image of soft tissue in a living body from a body surface by an ultrasonic pulse reflection method. Compared to other medical imaging equipment, this ultrasonic diagnostic device has features such as small size, low cost, no exposure to X-rays, high safety, blood flow imaging, etc., and the heart, abdomen, urology, Widely used in obstetrics and gynecology.

Further, the ultrasonic diagnostic apparatus is used not only for image diagnosis but also, for example, radiofrequency ablation (RFA) as a local treatment method for hepatocellular carcinoma, biopsy for examining hepatocyte tissue, and the like. In these treatments and examinations, a puncture needle must be used to accurately puncture a site of interest such as a tumor. For this reason, an ultrasonic diagnostic apparatus that can monitor the region of interest and the puncture needle in real time is used in order to clearly grasp where the puncture needle has entered the living body. In particular, in recent years, real-time three-dimensional ultrasound images may be used due to the speeding up of computers. In such a case, several methods for displaying the position of the puncture needle on the three-dimensional image during the puncture treatment and displaying the direction of the puncture needle as a guide have been proposed. (For example, refer to Patent Document 1).
Japanese Patent Laid-Open No. 6-205776

  However, when the conventional ultrasonic diagnostic apparatus is used for puncture, for example, the following problems exist.

  First, at the time of insertion of a puncture needle, it is not always possible to display a three-dimensional image from an observation angle at which the puncture needle and the treatment site can be viewed well. That is, in normal puncture, a part is identified by observation while rotating a three-dimensional ultrasonic image before puncture, and puncture is made toward a treatment part while monitoring with a three-dimensional image at a certain observation angle during puncture. Insert the needle. However, when the image is rotated before monitoring during puncture, the puncture needle may be hidden in the tissue image of the three-dimensional ultrasonic image, and the state where the position of the puncture needle is difficult to see may occur.

  Also, when the display position relationship between the puncture needle and the puncture target site cannot be properly observed in the image used for monitoring, such as the direction in which the puncture needle is inserted toward or away from the operator's position. Is necessary to rotate the three-dimensional ultrasonic image during puncturing, which is a burden on the operator.

  Furthermore, since the puncture needle in the three-dimensional image is displayed as a line, it may be difficult to grasp the positional relationship with the tissue or the like behind or in front of the puncture needle.

  The present invention has been made in view of the above circumstances, and in the case of monitoring a treatment site and a puncture needle using a three-dimensional image in puncture, it is possible to easily recognize the positional relationship between the puncture needle and the treatment site.

An ultrasonic diagnostic apparatus control method comprising:

  As described above, according to the present invention, when monitoring a treatment site and a puncture needle using a three-dimensional image in puncture, an ultrasonic diagnostic apparatus that facilitates visual recognition of the positional relationship between the puncture needle and the treatment site and a control method thereof Can be realized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, components having substantially the same function and configuration are denoted by the same reference numerals, and redundant description will be given only when necessary.

  FIG. 1 is a diagram showing a block configuration of an ultrasonic diagnostic apparatus 10 according to the present embodiment. As shown in the figure, the ultrasonic diagnostic apparatus 10 includes a puncture needle adapter 11, an ultrasonic probe 12, an operation panel 13, a display unit 14, a transmission / reception unit 21, a two-dimensional image configuration 22, a three-dimensional image configuration unit 23, A display image composition unit 25, a system control unit 27, a storage unit 28, a puncture needle position detection unit 30, and a puncture needle position image (two orthogonal cross sections) configuration unit 32 are provided. Hereinafter, the function of each component will be described.

  The puncture needle adapter 11 is an auxiliary tool provided on the ultrasonic probe 12 for fixing the needle at a predetermined angle by mounting the puncture needle.

  The ultrasonic probe 12 generates an ultrasonic wave based on a drive signal from the ultrasonic transmission / reception unit 21, converts a reflected wave from the subject into an electric signal, and a matching layer provided in the piezoelectric vibrator. And a backing material for preventing the propagation of ultrasonic waves from the piezoelectric vibrator to the rear. When ultrasonic waves are transmitted from the ultrasonic probe 12 to the subject P, the transmitted ultrasonic waves are successively reflected by the discontinuous surface of the acoustic impedance of the body tissue and received by the ultrasonic probe 12 as an echo signal. . The amplitude of this echo signal depends on the difference in acoustic impedance at the discontinuous surface that is to be reflected. In addition, the echo when the transmitted ultrasonic pulse is reflected by the moving blood flow or the surface of the heart wall depends on the velocity component in the ultrasonic transmission direction of the moving body due to the Doppler effect, and the frequency Receive a shift.

  The operation panel 13 is connected to the apparatus main body 11, and various switches and buttons, a trackball, a mouse for inputting various parameter conditions from the operator to the apparatus main body 11 and instructions for setting a region of interest (ROI). , Keyboard, TCS (Touch Command Screen) and the like.

  The display unit 14 displays in-vivo morphological information and blood flow information as an image based on the video signal from the display image synthesis unit 25.

  The transmission / reception unit 21 includes an ultrasonic pulse trigger generation circuit, a transmission delay circuit, a pulsar circuit, and the like (not shown). In the ultrasonic pulse trigger generation circuit, an ultrasonic transmission pulse trigger signal is generated for each channel at a predetermined transmission frequency f0 Hz. Further, in the transmission delay circuit, a delay time necessary for focusing the ultrasonic transmission beam for each channel and determining the transmission directivity is given to the ultrasonic transmission pulse trigger signal for each channel. The pulser circuit applies a drive pulse to the probe 12 at a timing based on the ultrasonic transmission pulse trigger signal.

  The transmission / reception unit 21 includes an amplifier circuit, an A / D converter, a reception delay adder, and the like that are not shown. The amplifier circuit amplifies the echo signal captured via the probe 12 for each channel. The A / D converter converts the amplified echo signal from an analog signal to a digital signal for each channel. In the reception delay adder, a delay time necessary for determining the reception directivity is given to each channel with respect to the echo signal converted into the digital signal, and then the addition processing is performed in the adder. By this addition, the reflection component from the direction corresponding to the reception directivity of the echo signal is emphasized, and a comprehensive beam for ultrasonic transmission / reception is formed by the reception directivity and the transmission directivity.

  The two-dimensional image configuration unit 22 includes a two-dimensional memory 22a and a two-dimensional image generation unit 22b. The two-dimensional memory 22 a records the echo signal for each scanning line received from the transmission / reception unit 21. The two-dimensional image generation unit 22b receives an echo signal from the transmission / reception unit 21, performs logarithmic amplification, envelope detection processing, and the like, and configures B-mode information in which the signal intensity is expressed by brightness. Further, the two-dimensional image generation unit 22b performs frequency analysis on velocity information from the echo signal received from the transmission / reception unit 21, extracts blood flow, tissue, and contrast agent echo components due to the Doppler effect, and calculates average velocity, dispersion, power, and the like. Construct blood flow information. The B-mode information and blood flow information configured by the two-dimensional image configuration unit 22 are sent to the display image synthesis unit 25 and displayed on the display unit 14 in a predetermined form.

  The three-dimensional image construction unit 23 includes a three-dimensional memory 23a and a three-dimensional image generation unit 23b. The three-dimensional memory 23a receives a plurality of two-dimensional images formed by the two-dimensional image construction unit 22, arranges them spatially (along the thickness direction), and performs an interpolation process as necessary. 3D image data (volume data) is configured. The three-dimensional image generation unit 23 b generates a three-dimensional image related to the observation angle (gaze direction) that has been initially set and the observation angle specified via the operation panel 13 using the configured three-dimensional image data. The three-dimensional image generated by the three-dimensional image constructing unit 23 is sent to the display image synthesizing unit 25 and displayed on the display unit 14 in a form synthesized with, for example, orthogonal two cross sections described later.

  The display image synthesizing unit 25 synthesizes an ultrasonic image received from each of the two-dimensional image forming unit 22 and the three-dimensional image forming unit 23 and a puncture needle position image described later to generate a display image. This synthesis can be realized by taking the correspondence between the position detected by the puncture needle position detection unit 30 and the coordinate system (volume coordinate system) in the volume data. The generated display image is combined with character information of various setting parameters, scales, and the like, and is output to the display unit 14 as a video signal.

  The system control unit 27 has a function as an information processing apparatus (computer) and statically or dynamically controls the operation of the main body of the ultrasonic diagnostic apparatus.

  The storage unit 28 stores image data acquired by the ultrasonic diagnostic apparatus, image data acquired by a transmission / reception unit (not shown) via a network, and various data groups such as various diagnostic protocols and ultrasonic transmission / reception conditions.

  The puncture needle position detection unit 30 detects the position of the tip of the puncture needle. The puncture needle position detection unit 30 may be anything as long as it can detect the position of the tip of the puncture needle. For example, the position of the tip of the puncture needle can be detected by detecting the insertion distance from the reference position of the puncture needle adapter 13. If the insertion distance from the reference position of the puncture needle does not reach a predetermined value, it can be determined that the puncture needle is not inserted.

  The puncture needle position image construction unit 32 generates a puncture needle position image based on the position of the puncture needle detected by the puncture needle position detection unit 30 and the puncture needle mounting direction of the puncture adapter 13. Here, the puncture needle position image is an image for making it easier to visually recognize the position of the puncture needle visualized on the three-dimensional image. The generation and display of the puncture needle position image will be described in detail later.

(Observation angle switching function)
Next, the observation angle switching function of the ultrasonic diagnostic apparatus 10 will be described. This function automatically switches the observation angle of the three-dimensional image (that is, the line-of-sight direction in the generation of the three-dimensional image) to a pre-registered angle with a predetermined operation as a trigger. By this function, the operator can easily visually recognize the positional relationship between the puncture needle and the treatment site without performing any special operation during the puncture operation by registering a suitable observation angle in advance.

  2 and 3 are conceptual diagrams for explaining the observation angle switching function. For example, the observation angle at which the treatment site D is displayed as shown in FIG. 2 is registered in advance prior to the puncture. This registration is realized by the system control unit 27 writing the observation angle in its own memory area or a predetermined area of the storage unit 28 in response to the input of the observation angle from the operation panel 13.

  When a predetermined operation (such as a switching instruction input from the operation panel 13) is executed at an arbitrary timing after registration, the three-dimensional image is switched from the registered observation angle in response to the operation. That is, the three-dimensional image construction unit 23 generates a three-dimensional image related to the registered observation angle in response to a predetermined operation under the control of the system control unit 27. The generated image is processed by the display image composition unit 25 and displayed on the display unit 14. Therefore, for example, when a predetermined operation as a trigger is executed during the display of the image related to the observation angle shown in FIG. 3, the three-dimensional image is changed from the observation angle shown in FIG. 3 to the observation angle shown in FIG. Will be switched to.

  The trigger for executing the switching of the observation angle is not limited to a predetermined operation via the operation panel 13. For example, the observation angle may be switched using as a trigger detection of a puncture needle by the puncture needle position detection unit 30, detection of insertion of a predetermined length of the puncture needle by the puncture needle position detection unit 30, and the like. It is preferable that which operation is a trigger can be selected by setting.

(Puncture needle position image generation and display function)
Next, the function of generating and displaying a puncture needle position image that the ultrasonic diagnostic apparatus 10 has will be described. This function is to generate a puncture needle position image based on the detected position of the puncture needle and display it together with a three-dimensional ultrasonic image. Here, the puncture needle position image is an image that supports the puncture needle on the three-dimensional image so that it can be easily seen. Therefore, any device can be used as long as it achieves the same effect. However, in terms of the characteristics of the ultrasonic image, in particular, it is easy to determine the position of the scanning plane including the puncture needle. What makes it easy to determine the near side and its back is preferable.

  FIG. 4 is an example of a puncture needle position image and is a diagram showing two orthogonal cross sections including the puncture needle. When the two orthogonal bullet planes are used as the puncture needle position image, the puncture needle position image is combined with the ultrasonic image and displayed as shown in FIG. 5, for example. The operator can easily visually recognize the positional relationship between the volume data V and the puncture needle N (particularly, from the puncture needle N to the front and the back thereof) based on the positions of the plane A and the plane B.

  The puncture needle position image may be displayed by using, for example, a predetermined operation via the operation panel 13, a detection of insertion of the puncture needle by the puncture needle position detection unit 30, detection of a predetermined insertion length, and the like as a trigger. It is preferable that which operation is a trigger can be selected by setting. In order to make the overlapping puncture needle visible, it is preferable that the puncture needle position image is translucent and its transmittance can be controlled.

  Further, as a support for specifying a puncture treatment site described later, the position of the puncture needle adapter and the insertion direction of the puncture needle by the adapter are displayed as a reference line on the ultrasonic image. In such a case, it is desirable that the reference line is expressed by an intersection line of two orthogonal cross sections. In such a configuration, even when the puncture needle is bent due to a hard tissue or the like, the intersecting line of the two orthogonal cross sections displays the puncture guide, so that it is easy for the operator to identify that the puncture needle is bent. .

(Clipping function based on the position of the puncture needle)
Next, the clipping function based on the position of the puncture needle that the ultrasonic diagnostic apparatus 10 has will be described. This function is a clipping process based on the position of the detected puncture needle (that is, a process that removes volume data in front of the clipping plane including the puncture needle and cuts out volume data existing on the clipping plane and the back side thereof) ), And a three-dimensional image is generated and displayed using the partial volume data obtained thereby. By this function, the tissue existing in front is not superimposed on the puncture needle, and the puncture needle can be visually recognized more suitably.

  6 and 7 are conceptual diagrams for explaining the clipping function based on the position of the puncture needle. When the puncture needle is inserted in a form as shown in FIG. 6, for example, the three-dimensional image generation unit 23b executes a clipping process, and is a part on the back side of the clipping plane C (see FIG. 7). Cut volume data v. The clipping surface includes the puncture needle N and the apex T (that is, the probe contact position). In addition, the 3D image generation unit 23b generates a 3D image using the volume data v obtained by the clipping process. The generated three-dimensional image is processed in the display image composition unit 25 and displayed on the display unit 14 in a form as shown in FIG. 7, for example. As a result, the puncture needle and the tissue existing before the clipping plane C do not overlap each other, so that the operator can visually recognize the positional relationship between the puncture needle and the treatment site.

  The puncture needle adapter may be displaced with respect to the position of the ultrasonic probe 12 during puncture. In such a case, it is preferable that the display position of the puncture needle position image is fixed as viewed from the operator, and the three-dimensional image is shifted automatically or by manual operation so as to correct the deviation.

  The observation angle switching function, the puncture needle position image generation / display function, and the clipping function based on the position of the puncture needle described above can be used in combination with other functions. For example, when the generation / display function of the puncture needle position image and the clipping function based on the position of the puncture needle are used in combination, volume data behind the plane B in FIG. 5 cut out by the clipping process is used. A three-dimensional image is generated.

  Further, clipping processing using two orthogonal cross sections (plane A and plane B) used for displaying the puncture needle position may be executed. For example, in FIG. 5, for example, among the four areas of the volume data divided by the plane A and the plane B, the most existing area is clipped so that the position of the puncture needle existing in the tissue is more suitable. It can be visually recognized.

(Operation)
Next, an operation when the ultrasonic diagnostic apparatus 1 is used for puncture monitoring will be described. For the sake of specific description, the observation angle switching is triggered by an instruction input from the operation panel 13.

  FIG. 8 is a flowchart showing the flow of each process executed during monitoring of puncture. As shown in the figure, first, information related to the patient (patient information: patient ID, treatment site, etc.) is input (step S1). Next, a volume scan is performed on the region including the treatment site, and the puncture treatment site is determined while rotating or moving the three-dimensional image obtained thereby (step S2). In this puncture treatment site determination, not only a three-dimensional image but also an orthogonal three-section display using an MPR image may be employed.

  Next, the line-of-sight angle θ that is considered suitable for visually recognizing the treatment site and the puncture needle during the puncture operation is registered (step S3). That is, when the line-of-sight angle θ is input via the operation panel 13, the system control unit 27 stores the line-of-sight angle θ in its own memory area or storage area 28. Thereafter, the observation angle can be switched at a desired timing by inputting an instruction from the operation panel 13.

  Next, when the puncture needle is inserted along the displayed puncture guide (step S4), a puncture needle position image is generated and displayed using the insertion of the puncture needle into the subject as a trigger (step S5). In addition, for example, a clipping-processed ultrasonic image is generated and displayed using a subject insertion having a length equal to or longer than a certain threshold position of the puncture needle as a trigger (step S6). The surgeon inserts the puncture needle to the target position while visually recognizing the positional relationship between the puncture needle and the treatment site based on the composite image of the displayed ultrasound image and puncture needle position image, and performs treatment such as cauterization. (Step S7).

  According to the configuration described above, the following effects can be obtained.

  According to this ultrasonic diagnostic apparatus, it is possible to automatically switch a display image to a three-dimensional image at a pre-registered observation angle with a predetermined operation as a trigger. Therefore, since it is not necessary to perform a special operation, the work load during puncture can be reduced. In addition, the visual recognition of the positional relationship between the puncture needle and the treatment site can be supported, which can contribute to the improvement of the quality of medical practice.

  Further, according to the ultrasonic diagnostic apparatus, a puncture needle position image can be displayed together with a monitoring three-dimensional image. Therefore, it is possible to support the grasp of the position of the puncture needle in the three-dimensional image, particularly the positional relationship between the puncture needle and the treatment target in the depth direction, the cross section including the puncture needle, etc., which contributes to the improvement of the quality of medical practice. be able to.

  Furthermore, according to the present ultrasonic diagnostic apparatus, clipping processing based on the detected position of the puncture needle is executed, and a three-dimensional image is generated and displayed using partial volume data obtained thereby. For this reason, tissue existing in front of the clipping plane (ie, the puncture needle) is not superimposed on the puncture needle. As a result, it is possible to support the grasp of the positional relationship between the puncture needle and the treatment target, and the quality of medical practice It can contribute to improvement.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Specific examples of modifications are as follows.

  (1) Each function according to the present embodiment can also be realized by installing a program for executing the processing in a computer such as a workstation and developing the program on a memory. At this time, a program capable of causing the computer to execute the technique is stored in a recording medium such as a magnetic disk (floppy (registered trademark) disk, hard disk, etc.), an optical disk (CD-ROM, DVD, etc.), or a semiconductor memory. It can also be distributed.

  (2) In the above embodiment, an example in which data before the clipping plane is removed by the clipping function based on the position of the puncture needle is shown. However, without being limited to this, for example, by reducing the transmittance of data before the clipping surface, it may be possible to prevent a decrease in the visibility of the puncture needle or the like by a tissue or the like existing in front of the clipping surface.

  In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.

  As described above, according to the present invention, when monitoring a treatment site and a puncture needle using a three-dimensional image in puncture, an ultrasonic diagnostic apparatus that facilitates visual recognition of the positional relationship between the puncture needle and the treatment site and a control method thereof Can be realized.
