Hereinafter, embodiments of the present invention will be described in detail.
(First embodiment)
First, a first embodiment will be described with reference to FIGS. An ultrasonic diagnostic apparatus 1 illustrated in FIG. 1 includes an ultrasonic probe 2, a transmission / reception beam former 3, an echo data processing unit 4, a display control unit 5, a display unit 6, an operation unit 7, a control unit 8, and a storage unit 9.

  The ultrasonic probe 2 includes a plurality of ultrasonic transducers (not shown) arranged in an array, and transmits ultrasonic waves to the subject through the ultrasonic transducers, and echo signals thereof. Receive.

  The transmission / reception beam former 3 supplies an electrical signal for transmitting an ultrasonic wave from the ultrasonic probe 2 under a predetermined scanning condition to the ultrasonic probe 2 based on a control signal from the control unit 8. The transmission / reception beamformer 3 performs signal processing such as A / D conversion and phasing addition processing on the echo signal received by the ultrasonic probe 2, and the echo data after the signal processing is sent to the echo data processing unit 4. Output to.

  The echo data processing unit 4 performs signal processing for creating an ultrasound image on the echo data output from the transmission / reception beamformer 3. For example, the echo data processing unit 4 includes a B-mode data creation unit 41 and a contrast data creation unit 42 as shown in FIG.

  The B mode data creation unit 41 creates B mode data by performing B mode processing including logarithmic compression processing, envelope detection processing, and the like. The contrast data creating unit 42 performs processing for creating a contrast image in which the contrast agent administered to the subject is emphasized on the echo data output from the transmission / reception beam former 3 to create contrast data. . For example, the contrast data creating unit 42 performs a filter process for extracting a harmonic component of the echo signal. The contrast data creating unit 42 may perform a process of extracting an echo signal from the contrast agent by a pulse inversion method. The contrast data creating unit 42 subtracts echo data based on echo signals obtained by transmitting ultrasonic waves having different amplitudes, and extracts a signal component from the contrast agent (amplitude modulation method: Amplitude Modulation). May be performed.

  As shown in FIG. 3, the display control unit 5 includes an image data creation unit 51, a target identification unit 52, and a display image control unit 53. The image data creating unit 51 performs scan conversion on the B-mode data and the contrast data by a scan converter to create B-mode image data and contrast image data.

  The target specifying unit 52 specifies the contour of the target region in the subject in the B-mode image. In this example, the target specifying unit 52 specifies the contour of the target region in the subject based on the B mode data (raw data) or the B mode image data. In the present example, the target region is a region of a tumor in the subject, and is a low luminance region whose luminance is lower than that of the surroundings in the B-mode image. The target specifying unit 52 performs processing for specifying the contour of the low-luminance region based on the B-mode data or the B-mode image data (data value corresponding to the luminance of the B-mode image).

  The target specifying unit 52 is an example of an embodiment of the target specifying unit in the present invention. The function executed by the target specifying unit 52 is an example of an embodiment of the target specifying function in the present invention.

  The B-mode data and the B-mode image data are referred to as B-mode image data.

  The display image control unit 53 causes the display unit 6 to display a B mode image based on the B mode image data. Further, the display image control unit 53 causes the display unit 6 to display a contrast image based on the contrast image data.

  Further, the display image control unit 53 differs in a contrasted image having the same cross section as the B-mode image of the subject in a stained portion inside the contour of the target region and a stained portion outside the contour of the target region. An image in the display form is displayed. The stained portion of the contrast image is a portion having brightness in the contrast image, that is, a portion where a signal exists in the contrast data and the contrast image data. However, in addition to the portion displayed based on the echo signal from the contrast agent, the shaded portion may include a portion displayed based on the echo signal from the living tissue.

  The display image control unit 53 is an example of an embodiment of a display image control unit in the present invention. The function executed by the display image control unit 53 is an example of the embodiment of the display image control function in the present invention.

  The display unit 6 is an LCD (Liquid Crystal Display), an organic EL (Electro-Luminescence) display, or the like. The operation unit 7 includes a keyboard for the operator to input instructions and information, a pointing device, and the like.

  The control unit 8 is a CPU (Central Processing Unit), reads a control program stored in the storage unit 9, and executes functions in each unit of the ultrasonic diagnostic apparatus 1. For example, the functions of the transmission / reception beamformer 3, the echo data processing unit 4, and the display control unit 5 may be executed by the control program.

  The storage unit 9 is, for example, an HDD (Hard Disk Drive) or a semiconductor memory.

  Now, the operation of the ultrasonic diagnostic apparatus 1 of this example will be described based on the flowchart of FIG. First, in step S <b> 1, the operator uses the ultrasonic probe 2 to start transmission / reception of ultrasonic waves with respect to a subject into which a contrast medium has been injected. Here, transmission / reception of ultrasonic waves for B-mode images and transmission / reception of ultrasonic waves for contrast images are alternately performed for each frame while the ultrasonic probe is at the same position.

  Next, in step S2, B-mode image data is created after the B-mode data is created based on the ultrasonic echo signal. Further, after the contrast data is created based on the ultrasonic echo signal, the contrast image data is created.

  Next, in step S3, the target specifying unit 52 specifies the contour of the tumor region based on the B-mode image data. For example, the target specifying unit 52 may specify the contour of the tumor region by performing binarization processing on the B-mode image data based on a preset threshold value. The target specifying unit 52 may perform threshold processing based on a threshold set based on a difference between data values of adjacent pixels to specify the contour of a tumor region (for example, Japanese Patent Application Laid-Open No. 2011-2011). (See 2000028 publication). In addition, the target specifying unit 52 may specify the contour of the tumor region by using other known methods.

  However, the target specifying unit 52 may specify the contour of the tumor region using B-mode data instead of the B-mode image data.

  Next, in step S4, the display image control unit 53 causes the display unit 6 to display a B-mode image BI and a contrast image CI as shown in FIG. The B-mode image BI and the contrast image CI are images of the same cross section in the subject, for example, an image of a mammary gland. In the B-mode image BI shown in FIG. 5, the portion indicated by the symbol CR (the portion having a high dot density) is a tumor region.

  The display image control unit 53 displays the first identification image II1 and the second identification image II2 on the shaded portion of the contrast image CI. In this example, the first identification image II1 and the second identification image II2 are color images of different colors, and display forms thereof are different from each other.

  Here, the different colors mean that any one of three elements of colors, that is, hue, brightness, and saturation is different. However, it is desirable that the first identification image II1 and the second identification image II2 are displayed in colors that are easily distinguishable from each other.

  For example, the first identification image II1 and the second identification image II1 are displayed in a translucent manner so that the shaded portion of the background can be seen through. Alternatively, the first identification image II1 and the second identification image II1 may be displayed so as to be superimposed on the background dyed portion (in a state where the dyed portion cannot be seen through).

  The first identification image II1 is a portion indicated by a vertical line in FIG. 5, and is displayed in a shaded portion inside a portion corresponding to the contour of the tumor region CR in the contrast image CI. On the other hand, the second identification image II2 is a portion indicated by a horizontal line in FIG. 5, and is displayed on a dyed portion outside the portion corresponding to the contour of the tumor region CR in the contrast image CI.

  Since the B-mode image BI and the contrast image CI are images of the same part in the subject, the same part in the subject and the contour of the tumor region CR specified based on the B-mode image data are the contrast image. The first identification image II1 and the second identification image II2 are displayed in the CI.

  Here, the effect of this example will be described as compared with the case where the first identification image II1 and the second identification image II2 are not displayed in the contrast image CI. FIG. 6 shows a contrast image CI ′ in which the first identification image II1 and the second identification image II2 are not displayed. In the contrast image CI ′, a portion with a dot is a dyed portion. In the drawings other than FIG. 6, the dyed portion is indicated by dots for convenience of explanation.

  When the operator determines whether there is a stained portion of the contrast image CI ′ outside the tumor region CR and performs a benign / malignant discrimination of the tumor, as shown in FIG. When the first identification image II1 and the second identification image II2 are not displayed, it may be difficult to make the above determination even when looking at the B-mode image BI and the contrast image CI ′. However, in this example, as shown in FIG. 5, if the second identification image II2 is displayed outside the first identification image II1 displayed in the shaded portion of the tumor area, the operator Thus, it can be easily recognized that there is a dyed portion outside the region of the tumor. Therefore, the operator can easily perform the benign / malignant discrimination.

  Next, a modification of the first embodiment will be described. First, the first modification will be described. As shown in FIG. 7, the display image control unit 53 forms a portion corresponding to the contour of the tumor region CR in the contrast image CI, that is, a boundary portion between the first identification image II1 and the second identification image II2. The contour line OL indicating the contour of the tumor region may be displayed.

  Next, a second modification will be described. In the display image control unit 53, as shown in FIG. 8, the first identification image II1 and the second identification image II2 may be line images. In FIG. 8, the first identification image II1 and the second identification image II2 are hatched images. However, the first identification image II1 and the second identification image II2 have different shaded directions and different display forms. However, the first identification image II1 and the second identification image II2 only need to have different line directions, and the line direction is not limited to the oblique direction.

  Although not particularly illustrated, the first identification image II1 and the second identification image II2 may be images having different densities from each other.

(Second embodiment)
Next, a second embodiment will be described. The configuration and operation of the ultrasonic diagnostic apparatus of this example are basically the same as those in the first embodiment. However, in the step S4, as shown in FIG. 9, the display image control unit 53 applies a color image to the shaded portion outside the portion corresponding to the contour of the tumor region CR in the contrast image CI. Although the certain second identification image II2 is displayed, the first identification image II1 is not displayed. In the contrast image CI, a normal contrast image is displayed in a region (a region indicated by a dot) inside a portion corresponding to the contour of the tumor region CR. Accordingly, the second identification image II2 is an image having a display form different from the shaded portion inside the contour of the tumor region CR. In the present example, the second identification image II2 is an example of an embodiment of the identification image in the present invention.

  Also in this example, as shown in FIG. 9, if the second identification image II2 is displayed outside the stained portion of the normal contrast image displayed in the region of the tumor, the operator can It can be easily recognized that there is a dyed portion outside the region. Therefore, the operator can easily perform the benign / malignant discrimination.

  Next, a modification of the second embodiment will be described. First, the first modification will be described. The display image control unit 53, as shown in FIG. 10, in the contrast image CI, a portion corresponding to the contour of the region CR of the tumor, that is, a boundary portion between the normal contrast image and the second identification image II2. You may display the outline OL which shows the outline of the area | region of a tumor.

  Next, a second modification will be described. As shown in FIG. 11, the second identification image II2 may be a line image. Further, although not particularly illustrated, the second identification image II2 may be a dot image.

(Third embodiment)
Next, a third embodiment will be described. The configuration and operation of the ultrasonic diagnostic apparatus of this example are also basically the same as those in the first and second embodiments. However, in the step S4, the display image control unit 53, as shown in FIG. 12, the first identification image II1 that is a color image on a dyed portion inside the portion corresponding to the contour of the tumor region CR. Is displayed, but the second identification image II2 is not displayed. In the contrast image CI, a normal contrast image is displayed in a region outside the portion corresponding to the contour of the tumor region CR (a region indicated by dots). Therefore, the first identification image II1 is an image having a display form different from the dyed portion outside the outline of the tumor region CR. In the present example, the first identification image II1 is an example of an embodiment of the identification image in the present invention.

  Also in this example, as shown in FIG. 12, if the shaded portion of the normal contrast image is displayed outside the first identification image II1 displayed in the region of the tumor, the operator can It can be easily recognized that there is a dyed portion outside the region. Therefore, the operator can easily perform the benign / malignant discrimination.

  Next, a modification of the third embodiment will be described. First, the first modification will be described. The display image control unit 53, as shown in FIG. 13, in the contrast image CI, a portion corresponding to the contour of the region CR of the tumor, that is, a boundary portion between the first identification image II1 and the normal contrast image, You may display the outline OL which shows the outline of the area | region of a tumor.

  Next, a second modification will be described. As shown in FIG. 14, the first identification image II1 may be a line image. Further, although not particularly illustrated, the first identification image II1 may be a dot image.

(Fourth embodiment)
Next, a fourth embodiment will be described. The configuration and operation of the ultrasonic diagnostic apparatus of this example are also basically the same as those in the first to third embodiments. However, in the step S4, the display image control unit 53 may display a monochrome image instead of displaying a color image as the first identification image II1 and the second identification image II2. However, the display image control unit 53 sets the image of either the first identification image II1 or the second identification image II2 higher by a predetermined value than the luminance value of the shaded portion where the image is displayed. Display with a luminance value or a luminance value lower by a predetermined value.

  For example, in the contrast image CI, the display image control unit 53 obtains an image obtained by subtracting a predetermined value from each of the luminance values of the pixels in the shaded portion inside the portion corresponding to the contour of the tumor region CR. And displayed as the first identification image II1. In this case, in the contrast image CI, a normal contrast image is displayed on the outside of the portion corresponding to the contour of the tumor region CR. Therefore, the first identification image II1 is an image having a display form different from the dyed portion outside the outline of the tumor region CR. Said 1st identification image II1 is an example of embodiment of the identification image in this invention.

  The first identification image II1 is displayed with a lower luminance than the shaded portion of a normal contrast image. Therefore, as shown in FIG. 15, in the contrast image CI, a shaded portion appears outside the portion corresponding to the contour of the tumor region CR, and the first identification image II1 having a lower luminance than this shaded portion is If displayed on the inside of the shaded portion, the operator can easily recognize that the shaded portion exists outside the region of the tumor. Therefore, the operator can easily perform the benign / malignant discrimination.

  The first identification image II1 may be displayed with a higher brightness than the shaded portion of a normal contrast image. That is, the display image control unit 53 obtains an image obtained by adding a predetermined value to each of the luminance values of the pixels in the shaded portion inside the portion corresponding to the contour of the tumor region CR in the contrast image CI. The first identification image II1 may be displayed.

  In addition, the display image control unit 53 adds an image obtained by adding a predetermined value to each of the luminance values of the pixels in the shaded portion outside the portion corresponding to the contour of the tumor region CR in the contrast image CI. The second identification image II2 may be displayed. In this case, in the contrast image CI, a normal contrast image is displayed on the inside of the portion corresponding to the contour of the tumor region CR. Therefore, the second identification image II1 is an image having a display form different from the shaded portion inside the contour of the tumor region CR. Said 2nd identification image II2 is an example of embodiment of the identification image in this invention.

  The second identification image II2 is displayed with higher brightness than the shaded portion of a normal contrast image. Accordingly, as shown in FIG. 16, in the contrast image CI, a shaded portion is displayed inside a portion corresponding to the contour of the tumor region CR, and the second identification image II2 having a higher luminance than the shaded portion. However, if displayed on the outside of the stained portion, the operator can easily recognize that the stained portion exists outside the region of the tumor. Therefore, the operator can easily perform the benign / malignant discrimination.

  The second identification image II2 may be displayed with a lower luminance than the shaded portion of a normal contrast image. That is, the display image control unit 53 obtains an image obtained by subtracting a predetermined value from each of the luminance values of the pixels in the shaded portion outside the portion corresponding to the contour of the tumor region CR in the contrast image CI. The second identification image II2 may be displayed.

  Next, a modification of the fourth embodiment will be described. First, the first modification will be described. The display image control unit 53 sets one of the first identification image II1 and the second identification image II2 to a luminance value that is higher by a predetermined value than the luminance value of the shaded portion where the image is displayed. The other image is displayed as an image having a luminance value lower by a predetermined value than the luminance value of the shaded portion where this image is displayed. For example, in the contrast image CI, the display image control unit 53 obtains an image obtained by subtracting a predetermined value from each of the luminance values of the pixels in the shaded portion inside the portion corresponding to the contour of the tumor region CR. And displaying the first identification image II1 and an image obtained by adding a predetermined value to each of the luminance values of the pixels in the shaded portion outside the portion corresponding to the contour of the tumor region CR. It may be displayed as the second identification image II2. In this case, the second identification image II2 is displayed with higher brightness than the first identification image II1. Therefore, as shown in FIG. 17, if the second identification image II2 is displayed around the first identification image II1, the operator can confirm that there is a dyed portion outside the region of the tumor. It can be easily recognized. Therefore, the operator can easily perform the benign / malignant discrimination.

  Although not particularly illustrated, the second identification image II2 may be displayed with lower brightness than the first identification image II1. That is, the display image control unit 53 obtains an image obtained by adding a predetermined value to each of the luminance values of the pixels in the shaded portion inside the portion corresponding to the contour of the tumor region CR in the contrast image CI. The image obtained by subtracting a predetermined value from each of the luminance values of the pixels in the shaded portion outside the portion corresponding to the contour of the tumor region CR is displayed as the first identification image II1. It may be displayed as the second identification image II2.

  Next, a second modification will be described. As shown in FIG. 18, the display image control unit 53 may display an outline OL in a portion corresponding to the outline of the tumor region CR in the contrast image CI. In FIG. 18, in the contrast image CI, the first identification image II1 is displayed, and the contour line OL is displayed at a boundary portion between the first identification image II1 and the normal contrast image.

  As mentioned above, although this invention was demonstrated by each said embodiment, of course, this invention can be variously implemented in the range which does not change the main point. For example, the display form of the first identification image II1 and the second identification image II2 is an example, and in the contrast image CI, display forms that are different between the inner dyed portion and the outer dyed portion of the contour of the target region. It suffices if an image is displayed. For example, the first identification image II1 may be a color image, and the second identification image II2 may be a line image.

  In addition, the target specifying unit 52 adjusts the gain and dynamic range, processes using a spatial filter, and the like on the B mode data and the B mode image data, thereby performing a low luminance region and a high luminance. It is also possible to create black and white clear data with a clearer boundary between the region. This black and white clear data is different from the image data displayed on the display unit 6. This black and white clear data is also included in the B-mode image data.

  The target specifying unit 52 performs a process of specifying the contour of a tumor based on the black and white clear data. Since the black and white clear data is data in which the outline of the tumor area which is a low luminance area is clear, the tumor area can be specified more accurately.

  Moreover, in the said embodiment, although the said object specific | specification part 52 specifies the outline of the said target area | region by data processing, it is not restricted to this. For example, the operator inputs using the operation unit 7 to trace the outline of the target region in the B-mode image displayed on the display unit 6, and the target identification is performed based on the input. The unit 52 may specify the contour of the target area.

  The contrast image CI may be a parametric image in which a shaded portion is displayed in a different color depending on the time phase when the echo signal is acquired.
