Abstract: In executing projection processing for the purpose of enhancing the efficiency of diagnosis, if a threshold is reached again after a specific value of a pixel reaches the threshold in the x direction in which tomographic planes are arrayed, the execution of the projection processing is ended, and a projected image is generated.

Abstract: A system for displaying accumulated ultrasound images of tissue structures. A set of N image frames is used to produce a peak image display. Multiple peak image displays are produced by discarding the oldest image frame in the set of N image frames and replacing the discarded image frame with another more recent image frame. The more recent image frame is added to the set of image frames to produce a new set of N image frames. The new set of N image frames is used to produce another peak display image. If there is an undesirable amount of distortion or blur in the peak display images due to tissue motion, then the number of image frames in the set of N image frames can be reduced.
