Ultrasonic diagnostic apparatus and image processing apparatus
View Patent ↗In an ultrasonic diagnostic apparatus according to an embodiment, a separator separates an arbitrary region of a displayed object represented from image data, in a depth direction, based on a characterizing quantity included in the image data. An image generation controller generates an image to be displayed in which depth direction information is reflected on the arbitrary region of the displayed object, separated by the separator. A display controller causes a monitor being capable of providing a stereoscopic vision to display the image to be displayed generated by the image generation controller.
1. An ultrasonic diagnostic apparatus comprising:
a controller configured to
separate color Doppler image data into a plurality of groups, wherein each group represents a region in an imaged object,
wherein separating the image data into a plurality of groups comprises separating pixels included in the image data into the plurality of groups based on turbulence of each pixel included in the image data and a given threshold,
generate virtual volume data in which each of the plurality of groups comprises a two-dimensional image arranged in a depth direction in a virtual space with groups having a higher turbulence being arranged closer to a viewer, and
generate a stereoscopic image to be displayed in which each group in the virtual volume is displayed stereoscopically at a position corresponding to the turbulence in the depth direction within the stereoscopic image, by applying a volume rendering process to the virtual volume data; and
a display configured to display the stereoscopic image.
2. The ultrasonic diagnostic apparatus according to claim 1 , wherein the controller is configured to separate the pixels based on at least one of velocity and power in addition to the turbulence.
3. The ultrasonic diagnostic apparatus according to claim 2 , wherein the controller is configured to further separate the pixels based on luminance information.
4. The ultrasonic diagnostic apparatus according to claim 1 , wherein the controller is configured to separate the pixels based on luminance information in addition to the turbulence.
5. The ultrasonic diagnostic apparatus according to claim 1 , wherein the controller is configured to extract the groups comprising pixels with turbulence within a range specified by the given threshold.
6. The ultrasonic diagnostic apparatus according to claim 1 , wherein the controller is further configured to change depth direction information associated with the stereoscopic image to be displayed, based on an operation of an operator, and generate an updated stereoscopic image to be displayed on which the depth direction information set is reflected.
7. The ultrasonic diagnostic apparatus according to claim 1 , wherein the controller is further configured to separate the color Doppler image data by separating pixels representing intracardiac blood flow into a first group representing normal blood flow and a second group representing reverse blood flow, to generate second virtual volume data comprising a two-dimensional image of the first group and a two-dimensional image of the second group, wherein the two-dimensional image of the second group is arranged closer to the viewer in the depth direction than the two-dimensional image of the first group, and cause the display to display an image corresponding to the second virtual volume data.
8. The ultrasonic diagnostic apparatus according to claim 1 , wherein the controller is configured to automatically set the given threshold using the color Doppler image data.
9. An image processing apparatus comprising:
a controller configured to
separate color Doppler image data into a plurality of groups, wherein each group represents a region in an imaged object,
wherein separating the image data into a plurality of groups comprises separating pixels included in the image data into the plurality of groups based on turbulence of each pixel included in the image data and a given threshold,
generate virtual volume data in which each of the plurality of groups comprises a two-dimensional image arranged in a depth direction in a virtual space with groups having a higher turbulence being arranged closer to a viewer,
generate a stereoscopic image to be displayed in which each group in the virtual volume is displayed stereoscopically at a position corresponding to the turbulence in the depth direction within the stereoscopic image, by applying a volume rendering process to the virtual volume data, and cause a display to display the stereoscopic image.
10. A method comprising:
