BACKGROUND OF THE INVENTION
The present invention relates to a puncture needle guide and display of a puncture needle in ultrasonic diagnosis.
[0002]
[Prior art]
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.
[0003]
In diagnosis using this ultrasonic diagnostic imaging apparatus, there is a case where a puncture needle is inserted into a subject while observing an ultrasonic image, and a part of tumor cells is collected and examined with the puncture needle. In this case, a so-called puncture probe is used instead of a normal image acquisition probe. This puncture needle probe is equipped with a biopsy type in which a groove is provided in the center or asymmetrical position of a normal array probe and a puncture needle is inserted from the groove, or an adapter for puncture is attached to a normal array probe. There are adapter types to insert a puncture needle.
[0004]
When inserting a needle into a subject using such a puncture probe, a guideline as shown in FIG. 10 is usually displayed in an ultrasonic image. This guideline is fixedly displayed based on the insertion angle determined by an adapter or the like. The operator reaches the tumor while inserting a needle along the guideline, and performs a treatment such as cell intake.
[0005]
By the way, when a puncture needle is inserted into a subject to reach a tumor site, there are cases where blood vessels, bones, and the like are present on the path, which hinders puncture. In this case, the operator inserts the puncture needle sensuously so as to sensibly avoid blood vessels while observing the ultrasonic image.
[0006]
However, the conventional guideline displayed on the ultrasound image does not consider the presence of defects, bones, and the like. Therefore, when a puncture needle is inserted along the route indicated by the guideline, the needle may damage blood vessels and bones, causing bleeding, metastasis, and the like. Moreover, in order to insert a needle | hook so that a defect, a bone | frame, etc. may be avoided with the conventional system, an aspiration experience and advanced technique are required, and a burden with respect to an operator will become great.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, first and second 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.
[0015]
(First embodiment)
First, the configuration of the ultrasonic diagnostic apparatus 10 according to the present embodiment will be described with reference to FIG. As shown in FIG. 1, the ultrasonic diagnostic apparatus 10 includes an ultrasonic probe 11, an insertion portion guide 12, a pulser / amplifier unit 13, an A / D converter 15, a detection unit 16, a filter processing unit 18, and a B mode processing unit. 19, Doppler processing unit 21, image processing unit 22, DSC 23, display control unit 24, display unit 25, and input unit 27.
[0016]
The ultrasonic probe 11 generates an ultrasonic wave based on a drive signal from a pulser and converts a reflected wave from a subject into an electric signal, a matching layer provided in the piezoelectric vibrator, and the piezoelectric vibration. It has a backing material that prevents the propagation of ultrasonic waves from the child to the rear. When ultrasonic waves are transmitted from the ultrasonic probe 11 to the subject, various harmonic components are generated along with the propagation of the ultrasonic waves due to nonlinearity of the living tissue. The fundamental wave and the harmonic component constituting the transmission ultrasonic wave are back-scattered by the boundary of acoustic impedance of the body tissue, minute scattering, and the like, and are received by the ultrasonic probe 11 as a reflected wave (echo).
[0017]
The insertion portion guide 12 is provided at a predetermined position such as the side surface of the probe 11 and designates the insertion position of the puncture needle into the subject in the treatment using the puncture needle (hereinafter also referred to as “puncture treatment”). It is a jig for. FIG. 2 shows a top view of the insertion portion guide 12. As shown in the figure, the insertion portion guide 12 has a plurality of insertion holes 120 arranged to guide the insertion position of the puncture needle. The operator determines a puncture route that avoids blood vessels and the like by aligning one end of a puncture needle guide marker, which will be described later, with one of the plurality of insertion holes 120 and the other end with the tumor. By inserting a puncture needle through the insertion hole 120 located at one end of the puncture route determined in this way, a safe puncture treatment can be executed.
[0018]
FIG. 3 is a view showing a modified example of the insertion portion guide 12. The insertion portion guide 12 shown in the figure has a first guide 12A and a second guide 12B that are both slidable in the horizontal direction. By adjusting the positional relationship between the first guide 12A and the second guide 12B and passing each guide through a predetermined insertion hole 120, not only the insertion position of the puncture needle but also the insertion angle can be determined. . The positional relationship between the first guide 12A and the second guide 12B may be adjusted by an operator's manual operation. However, a moving mechanism for moving each guide horizontally is provided, and this is provided on the apparatus body. It may be configured to be automatically executed by controlling according to the instruction.
[0019]
The pulsar / amplifier unit 13 repeatedly generates a rate pulse at a predetermined rate frequency fr Hz (cycle: 1 / fr sec) based on the control by the waveform control unit 14 to form a transmission ultrasonic wave at the time of transmission. Each rate pulse is given a delay time necessary for focusing the ultrasonic wave into a beam and determining the transmission directivity every time. The pulser / amplifier unit 13 applies a drive pulse to the probe 11 at a timing based on this rate pulse.
[0020]
Further, the pulser / amplifier unit 13 amplifies the echo signal captured via the probe 11 for each channel during reception. Further, at the time of reception, the pulser / amplifier unit 13 gives a delay time necessary for determining reception directivity to the amplified echo signal, and performs addition processing. By this addition, the reflection component from the direction corresponding to the reception directivity of the echo signal is emphasized, and the overall directivity (scanning line) of ultrasonic transmission / reception is determined by the reception directivity and the transmission directivity.
[0021]
The A / D converter 15 converts the analog signal received from the pulser / amplifier unit 13 into a digital signal.
[0022]
The detection unit 16 performs quadrature detection by multiplying the signal received from the A / D converter 15 by a signal having a reference frequency that is 90 degrees out of phase, and obtains I and Q signals. The I and Q signals are signals having a frequency obtained by subtracting the reference frequency from the received signal. The reference frequency is generally set to the center frequency of a band for generating an ultrasonic image.
[0023]
The filter processing unit 18 attenuates the reflected wave component of a predetermined frequency band, extracts (filters) the reflected wave component of a desired frequency band, and outputs the complex digital filter to the B-mode processing unit 19 or the Doppler processing unit 21 It is.
[0024]
The B-mode processing unit 19 performs logarithmic amplification or the like on the received signal that has been filtered. The amplified signal is sent to the DSC 23 via the image processing unit 22, and is displayed in color on the display unit 25 as a B-mode image in which the intensity of the reflected wave is expressed by luminance.
[0025]
The Doppler processing unit 21 extracts blood flow, tissue, and contrast agent echo components due to the Doppler effect, and obtains blood flow information such as average velocity, dispersion, and power at multiple points. The blood flow information is sent to the DSC 23 via the image processing unit 22, and is displayed in color on the display unit 25 as an average velocity image, a dispersion image, a power image, and a combination image thereof.
[0026]
The image processing unit 22 executes image reconstruction processing based on the outputs from the B-mode processing unit 19 and the Doppler processing unit 21 to generate voxel volume data. In the present embodiment, voxel volume data is generated based on morphological image data and based on structure image data. Here, the morphological image is an ultrasonic image relating to the substantial morphology of the tumor and its nearby tissue, and can be collected by B-mode imaging or the like. On the other hand, the structure image is an ultrasound image related to the blood vessel structure and can be collected by Doppler mode imaging or imaging by contrast echo method using a contrast agent (including harmonic imaging, flash echo imaging, etc.).
[0027]
The image processing unit 22 executes rendering processing based on the obtained volume data, and generates a tomographic image and a three-dimensional image related to the form or structure. Furthermore, the image processing unit 22 combines the image related to the form and the image related to the structure to generate a combined image in which the form and the structure are displayed at the same time. The generation of the composite image will be described in detail later.
[0028]
The DSC 23 converts the image signal sequence for each scanning line input from the image processing unit 22 into orthogonal coordinate system data based on the spatial information, and further performs video format conversion.
[0029]
The display control unit 24 simulates the puncture needle and designates a puncture needle guide marker for designating a safe puncture route on the ultrasound image, and the insertion portion guide 12 and punctures on the ultrasound image. An insertion portion guide marker for designating the insertion position of the needle is generated. The generated puncture needle guide marker and insertion portion guide marker are displayed on the display unit 25 so as to be superimposed on the ultrasonic image.
[0030]
Further, when the position movement of the puncture needle guide marker is instructed via the display unit 25 and the input unit 27, the display control unit 24 moves the puncture needle guide marker to the instructed position.
[0031]
The display unit 25 displays morphological information in the living body and structural information such as blood vessels based on blood flow as images based on the video signal from the DSC 23. In addition, when a contrast agent is used, structural information such as blood vessels is represented as a luminance image based on the quantitative distribution of the spatial distribution of the contrast agent, that is, the blood flow or the region where the blood exists. Or as a color image. The display unit 25 displays a puncture needle guide marker and an insertion unit guide marker together with each image in response to a predetermined operation.
[0032]
The input unit 27 is connected to the main body of the apparatus 10 and is used to set a region of interest (ROI) for incorporating various instructions, commands, and information from the operator into the apparatus main body (mouse, trackball, mode switching, etc. Switches, keyboards, etc.) are provided. In addition, the transmission condition of the transmission ultrasonic wave can be manually input via the input unit 27.
[0033]
(Composite image of morphological image and structure image)
Next, a composite image of the morphological image and the structure image generated by the apparatus 10 will be described. Hereinafter, a composite image composed of a morphological image (tissue tomographic image) obtained by B-mode imaging and a three-dimensional blood vessel image based on a structure image obtained by color Doppler mode will be described as an example.
[0034]
FIG. 4 is a flowchart showing a flow of a series of processes from image data collection by ultrasonic scanning to composite image display. As shown in the figure, volume data including morphological images is obtained by three-dimensionally scanning an organ or the like to be diagnosed with B-mode imaging using ultrasound. Further, the same organ or the like is three-dimensionally scanned with ultrasonic waves by color Doppler mode imaging to obtain volume data composed of a structure image at substantially the same time as the morphological image (step S1). In imaging in each mode, when the probe 11 is a one-dimensional array probe, volume data relating to a region including a diagnosis target can be collected by mechanically or artificially instigating the probe 11. If the probe 11 is a two-dimensional array probe, volume data relating to a region including a diagnosis target can be automatically collected by performing a three-dimensional scan.
[0035]
Note that each image data collected in each shooting mode can be associated with a position in the real space, and accordingly, a position can also be associated between image data collected in different shooting modes.
[0036]
Next, the image data acquired in each shooting mode is reconstructed (step S2). In this reconstruction process, voxel volume data relating to the area including the diagnosis target is generated. Hereinafter, voxel volume data corresponding to B-mode imaging is referred to as first volume data, and voxel volume data corresponding to color Doppler mode imaging is referred to as second volume data.
[0037]
Next, processing such as cross-sectional transformation (MPR) processing and texture mapping is executed based on the position of the designated tomographic plane, and tissue tomogram (F (x, y, z): black and white is obtained from the first volume data. Gradation image). Also, image processing such as volume rendering with a predetermined transparency is executed to generate a three-dimensional blood vessel image (G (x, y, z): color image) from the second volume data (step S3A, S3B). FIG. 5A shows an example of a predetermined tissue tomogram generated in step S3A, and FIG. 5B shows an example of a three-dimensional blood vessel image generated in step S3B. A dotted line shown in T of FIG. 5A represents, for example, a spherical tumor Tt.
[0038]
Next, a tissue tomographic image (F (x, y, z)) and a three-dimensional blood vessel image (G (x, y, z)) are synthesized while taking corresponding positions to generate a synthesized image (step S4). The synthesized image is displayed in a predetermined form (step S5), specifically, synthesized and displayed as follows: First, as shown in FIG. The tissue tomographic image T1 relating to a predetermined cross section (XY plane at the initial position on the Z axis) and the three-dimensional blood vessel image S relating to the viewpoint side (near side) along the Z axis from the tomographic image T1 are synthesized. Accordingly, the three-dimensional blood vessel image is not displayed on the back side of the tomographic image T1.
[0039]
Next, the operator (operator) can change the position of the tomographic image to be displayed along the Z axis by performing a predetermined operation input from the input unit 27. Thereby, the tissue tomographic image (B mode image) constituting the voxel volume data regarding the form can be sequentially displayed as if turning the page of the book.
[0040]
In FIG. 5D, an example of a tissue tomogram T2 displayed when the position on the Z-axis is shifted further than T1 by the operating means, FIG. 5E shows an example on the Z-axis. Examples of tissue tomographic images T3 displayed when the position is shifted further to the back than T2 are shown. In addition, the display of the blood vessel image S is automatically updated as shown in FIGS. 5C to 5E in accordance with the change in the cross-sectional setting from the tissue tomographic images T1 to T3.
[0041]
In the above example, a composite image composed of a tissue tomogram and a three-dimensional blood vessel image has been described. In contrast, as described in the second embodiment, three-dimensional data related to a tissue is collected, a three-dimensional tissue image is generated based on the collected three-dimensional tissue image, and a composite image composed of the three-dimensional tissue image and the three-dimensional blood vessel image is generated. The structure to produce | generate may be sufficient. In the above example, the blood vessel image is described as a Doppler image. However, a composition image may be generated that includes a blood vessel image obtained by contrast echo and a tissue tomographic image or a three-dimensional tissue image. Note that generation of a composite image composed of a morphological image obtained by B-mode imaging and a structure image obtained by color Doppler mode is described in detail, for example, in JP-A-11-164833.
[0042]
(Operation of this ultrasonic diagnostic device in puncture treatment)
Next, the operation of the ultrasonic diagnostic apparatus 10 configured as described above will be described with reference to FIGS. 6 to 8 by taking the case of puncture treatment as an example.
[0043]
FIG. 6 is a flowchart showing a series of operations when the ultrasonic diagnostic apparatus 10 is used to insert a puncture needle into a subject and collect a living tissue. As shown in the figure, first, in order to obtain morphological image data and structure image data, the subject is three-dimensionally scanned in the B mode and the color Doppler mode to obtain an echo signal (step S11). As described above, the structure image data may be acquired by the contrast echo method instead of the color Doppler mode.
[0044]
Next, a B-mode image is generated and displayed based on the echo signal obtained by B-mode imaging (step S12). The operator finds a site (tumor) to be a target for puncture treatment from the displayed B-mode image.
[0045]
Next, a composite image relating to at least a region (ie, an imaging region) including a region from the body surface to the tumor is generated and displayed (step S13). The processing executed in this step corresponds to steps S3A, 3B to S5 in FIG.
[0046]
Next, as shown in FIG. 7, the puncture needle guide marker and the insertion portion guide marker are displayed on the composite image (step S14). At this time, the insertion portion guide marker is displayed at an accurate position corresponding to the real space based on the position of the probe 11. On the other hand, the puncture needle guide marker is displayed at an initially set predetermined position.
[0047]
Next, by a predetermined operation, the puncture needle guide marker is moved on the composite image so as to avoid the blood vessel, and the puncture route is determined (step S15). By moving the puncture needle guide marker to a position where the blood vessel does not contact in this way, a safe puncture route of the puncture needle that is actually inserted into the subject can be navigated. In addition, what kind of thing may be sufficient as the process which moves a puncture needle guide marker. For example, in FIG. 8, first, one end corresponding to the needle tip of the puncture needle guide marker is clicked so that the one end can be moved, and dragging to the tumor position is performed by a determination operation such as double clicking. Further, the other end of the puncture needle guide marker (that is, the end opposite to the needle tip) is clicked so as to be movable, and while searching for a route that does not pass through the blood vessel while looking at the composite image, Drag to the point of the insertion guide marker to be displayed, and decide by operations such as double-clicking. In FIG. 8, the intersection portion of the lattice of the insertion portion guide marker corresponds to the insertion hole 120.
[0048]
Next, the operator inserts a puncture needle so as to pass through the determined puncture route while viewing the composite image (step S16). During insertion of the puncture needle, it is more preferable to display a composite image so that the actual progress of the puncture needle and the state in the vicinity of the tumor can be easily confirmed, but a B-mode image may be displayed.
[0049]
Next, when the puncture needle reaches the tumor via the puncture route, the operator collects the tissue of the tumor (step S17), and extracts the puncture needle from the subject (step S18).
[0050]
The puncture treatment using the ultrasonic diagnostic apparatus 10 is completed by the series of processes described above.
[0051]
According to the configuration described above, the following effects can be obtained.
According to the ultrasonic diagnostic apparatus 10, a safe puncture route that avoids blood vessels can be determined before insertion of a puncture needle. By inserting the puncture needle so as to pass through the puncture route, the operator can cause the puncture feather needle to reach the tumor without damaging the blood vessel or the like. As a result, a safe puncture treatment that does not induce bleeding or metastasis can be realized, and the burden on the operator can be reduced.
[0052]
Further, according to the ultrasonic diagnostic apparatus 10, it is possible to provide a B-mode image and a composite image together with the puncture route in the puncture treatment. Therefore, the operator can confirm the puncture status by his / her own visual inspection along with the guidance of the puncture needle through the puncture route, and can perform safer puncture treatment.
[0053]
The ultrasonic diagnostic apparatus 10 has various functions for assisting the operator in the puncture treatment. Each function will be described below.
[0054]
The ultrasonic diagnostic apparatus 10 has a function of notifying the operator of the distance between the puncture needle guide marker and the blood vessel. Specifically, the display form of the puncture needle guide marker is changed according to the distance between the puncture needle guide marker and the blood vessel (for example, when the puncture needle guide marker enters an area within a predetermined distance from the blood vessel. Yellow display, red display when in contact with blood vessel, etc.), or a warning that the blood vessel is approaching or in contact with the blood vessel is displayed or voiced.
[0055]
With this function, the operator can be actively notified of the environment around the puncture route. As a result, the operator can perform a safe puncture treatment relatively easily with the assistance of the apparatus.
[0056]
The ultrasonic diagnostic apparatus 10 has a function of selectively displaying a morphological image and a structure image. Thereby, after determining the puncture route, for example, by displaying only the structure image, the contact between the puncture route and the blood vessel can be easily confirmed.
[0057]
The ultrasonic diagnostic apparatus 10 can also automatically determine the puncture route based on the morphological image and the structure image. This is realized as follows. That is, the blood vessel on the structure image and the other part can be discriminated by the pixel value. Therefore, for example, when the position of the tumor is specified on the composite image by the operator, the image processing unit 22 selects a pixel having a pixel value equal to or less than a threshold value for distinguishing it from the blood vessel in the vicinity thereof. select. This process is sequentially executed from the starting point toward the insertion portion guide marker, and when the straight route can be determined, the route may be determined as the puncture route. When a plurality of puncture routes are determined by this method, it is preferable to recommend the puncture route that is the farthest from the blood vessel from the viewpoint of safety.
[0058]
Further, the ultrasonic diagnostic apparatus 10 has a function of instructing an insertion angle of the puncture needle by a puncture needle insertion guide. This can be realized by using the insertion portion guide shown in FIG. That is, if the puncture route is determined according to the procedure described above, the insertion angle of the puncture needle is determined at the same time. Therefore, the insertion direction of the puncture needle can be supported by adjusting the positional relationship between the first guide 12A and the second guide 12B based on the puncture route.
[0059]
(Second Embodiment)
In the second embodiment, an ultrasonic diagnostic apparatus 10 that determines a puncture route by inserting a puncture needle guide marker into a three-dimensional image and displaying the puncture needle guide marker on the same image will be described. That is, in the first embodiment, after the composite image is generated, the puncture needle guide marker is displayed in a superimposed manner on the composite image and moved to determine the puncture route. On the other hand, in the second embodiment, the puncture needle guide marker is reflected in each volume data, and a composite image is generated by synthesizing the morphological image and the structure image rendered based on this. In addition, the movement instruction of the puncture needle guide marker is sequentially fed back to each volume data. Thereby, a three-dimensional puncture needle guide marker that is visible and hidden between the morphological image and the structure image can be provided.
[0060]
In the present embodiment, a case where a three-dimensional tissue image and a three-dimensional blood vessel image are generated and a puncture needle guide marker is inserted into a composite image obtained based on the three-dimensional tissue image and displayed is taken as an example. In addition, the ultrasonic diagnostic apparatus according to the present embodiment has various functions for supporting the operator described in the first embodiment.
[0061]
FIG. 9 is a flowchart showing a series of operations when performing puncture treatment using the ultrasonic diagnostic apparatus 10 according to the present embodiment. Each process from step S21 to step S23 corresponds to each process from step S11 to step S13 shown in FIG. 6, and the contents are the same.
[0062]
When the composite image is displayed in step S23, the puncture needle guide marker and the insertion portion guide marker are displayed at the initially set positions by a predetermined operation (step S24). At this time, the puncture needle guide marker is displayed in a form embedded in the composite image. This is realized as follows.
[0063]
That is, when the predetermined operation is executed, the puncture needle guide marker is plotted at an initially set position on the voxel volume data corresponding to each mode obtained by image reconstruction. The image processing unit 22 performs a rendering process based on each volume data on which the puncture needle guide marker is plotted, and obtains a morphological image and a structure image. By synthesizing the obtained morphological image and structure image, a synthesized image in which the puncture needle guide marker is three-dimensionally fitted (hereinafter also referred to as “second synthesized image”) can be obtained. In addition, about the display of an insertion part guide marker, it displays on the predetermined position on the basis of the position of the probe 11 like 1st Embodiment.
[0064]
Next, the puncture needle guide marker is moved on the synthesized image so as to avoid the blood vessel by the same operation as in the first embodiment (step S25). The image processing unit 22 feeds back the position designated by the moving operation to each voxel volume data, and moves the puncture needle guide marker on each voxel volume data to the designated position. The image processing unit 22 performs a rendering process based on each voxel volume data after movement, and generates a second composite image (step S26). The generated second composite image is displayed in real time on the display unit 25 in a predetermined form (step S27). The puncture needle guide marker moving operation in step S25 is executed until a suitable puncture route can be determined. The feedback and rendering processing of the puncture needle guide marker position in step S26 is sequentially executed in real time every time the puncture needle guide marker moving operation is performed. Accordingly, the second composite image displayed on the display unit 25 is updated each time the puncture needle guide marker is moved.
[0065]
Next, the operator inserts a puncture needle so as to pass through the determined puncture route while viewing the second composite image (step S26), and collects tumor tissue and the like (step S27). Then, the puncture needle is extracted from the subject (step S28).
[0066]
The puncture treatment using the ultrasonic diagnostic apparatus 10 is completed by the series of processes described above.
[0067]
According to the configuration described above, the same effect as that of the first embodiment can be obtained. In addition, according to the ultrasonic diagnostic apparatus, it is possible to provide a three-dimensional puncture needle guide marker that appears and disappears between the morphological image and the structure image. Therefore, the blood vessel structure in the region from the body surface to the tumor can be grasped in more detail, and puncture treatment with high safety can be performed.
[0068]
Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components 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.
