Ultrasonic diagnostic apparatus and ultrasonic image display method

摘要

For generating ultrasonic projection images in which various kind of ultrasonic projection images have been appropriately combined, the invention is provided with: a storage unit that stores tomographic image volume data and elastic image volume data; a volume rendering unit that generates tomographic projection images by volume rendering on the basis of the tomographic image volume data; a display device that displays the ultrasonic projection images generated by the volume rendering unit; and an operation unit for inputting commands to control the volume rendering unit. For one of the rendering spaces partitioned by a cutting plane set in the rendering space by a command input from the operation unit, the volume rendering unit renders voxels of tomographic image volume data corresponding to the voxels of elastic image volume data that have elasticity values satisfying a set threshold value, and generates and displays the tomographic projection image on the display device.

主权项

1. An ultrasonic diagnostic apparatus comprising:
a volume rendering unit, executed by a processor, that generates a tomographic projection image and an elasticity projection image by performing volume rendering based on tomographic image volume data and elasticity image volume data of ultrasonic waves; and a display that displays a tomographic projection image and an elasticity projection image generated by the volume rendering unit, wherein the volume rendering unit, for one of a plurality of rendering spaces partitioned by a cutting plane which is set in the rendering space, renders voxels in the tomographic image volume data, generates the tomographic projection image, and displays the tomographic projection image on the display, wherein the volume rendering unit, for another one of the rendering spaces partitioned by the cutting plane set in the rendering space, renders the voxels in the tomographic image volume data corresponding to voxels in the elasticity image volume data having the elasticity values that belong to a set range, generates the tomographic projection image, and displays the tomographic projection image on the display.
