Problems solved by technology
Therefore, there is a problem that the fluoroscopic projection image in the lumen of the observation object is not displayed.
In addition, for example, when three-dimensional data is generated using a mechanical four-dimensional probe that performs three-dimensional scanning by swinging a one-dimensional array in a direction orthogonal to the arrangement direction of a plurality of vibrators, and the display method is executed, in the drawing In the continuous real-time display of images, there is a problem that the frame rate is not sufficient

The ultrasonic diagnostic apparatus according to this embodiment includes: an ultrasonic probe (8) having a plurality of ultrasonic vibrators; a position detecting unit (10) detecting position information of the ultrasonic probe (8) based on a predetermined reference position; a transmitting and receiving unit (21), supplying a driving signal to each ultrasonic vibrator, and generating a receiving signal based on each receiving echo signal generated by each ultrasonic vibrator; a three-dimensional data generation unit (23), generating first three-dimensional data based on the receiving signal; specific A part (25) specifies a region corresponding to a living body tissue in the three-dimensional data; a setting part (27) sets a first viewpoint based on the position information and the specified region; and an image generating part (29) uses the set The rendering process is performed using the predetermined first viewpoint and the first three-dimensional data, and a rendering image is generated.
Description
technical field [0001] Embodiments of the present invention relate to an ultrasonic diagnostic apparatus, a medical image processing apparatus, and a medical image processing method that generate rendered images. Background technique [0002] In recent years, ultrasonic diagnostic apparatuses that collect echo signals from a subject by three-dimensionally scanning the subject have been put into practical use. According to this ultrasonic diagnostic apparatus, it is possible to generate and display a three-dimensional image (for example, a rendered image, etc.) by generating three-dimensional data based on echo signals. In order to generate a three-dimensional image, for example, rendering processing (such as volume rendering, surface rendering, etc.) is performed on the three-dimensional data. The viewpoint, line of sight, angle of view, projection area, and the like used in rendering processing are set as three-dimensional data. After the above settings, a drawing image (...
