ABSTRACT:
A transmitter/receiver obtains scanning data by transmitting ultrasonic waves to a subject to be examined and receiving reflected waves from the subject to be examined. An image processor converts the scanning data into image data represented by a predetermined coordinate system and applies a predetermined smoothing process to the image data. The image processor calculates the vector of each point, based on the image data after the smoothing process. The image processor generates three-dimensional image data by applying a ray-tracing process to the image data to which the smoothing process has not been applied, according to the vector.
