Abstract
An ultrasonic diagnostic device is disclosed in which ultrasonic pulses are transmitted for a subject body in changing the position and direction of a probe, and a plurality of two-dimensional tomographic image signals obtained by detecting the reflected pulses are synthesized to form a three-dimensional image. A signal for identifying the position in three-dimensional coordinates based on the position and direction of the probe at the time of detection is given to individual picture element signals composing in the detected two-dimensional tomographic image. A plurality of two-dimensional tomographic image signals having identified positions in three-dimensional coordinates are obtained by the similar processes to described in the above in changing the position and direction of the probe, and a plurality of the picture element signals having the same coordinates are addition-averaged and are stored in the memory area corresponding to the coordinates in the three-dimensional memory. With the arrangement as described in the above, the three dimensional image can be formed which is not influenced by hardness in the tissue etc.
