Abstract:
An ultrasonic diagnostic apparatus, comprising:a three-dimensional scanner for carrying out a three-dimensional scanning by ultrasonic waves; a three-dimensional volume data former for forming three-dimensional volume data acquired through the three-dimensional scanning; a three-dimensional volume data memory for storing in time series a plurality of pieces of three-dimensional volume data from which display image is to be reconstructed; a display condition data former for forming display condition data indicating a direction of a projection and how the display image is displayed on a display unit; a display condition data memory for storing in time series a plurality of pieces of display condition data, each of which corresponds to each of the three-dimensional volume data stored in the three-dimensional volume data memory and used to reconstruct the display image; a memory controller for controlling write and read of the stored three-dimensional volume data and display condition data; and a display image processor for reconstructing display images based on three-dimensional volume data read out from the three-dimensional volume data memory and corresponding display condition data by the memory controller, and for displaying the reconstructed display image on a display unit.
