Abstract

The blood vessel imaging system includes a carriage for moving in a row direction an ultrasonic probe having a plurality of ultrasonic transducers arranged along a column direction and along the row direction. A computer repeats intermittent movement control for the carriage in shorter distance than a row pitch of the ultrasonic transducers along the row direction for each of a plurality of predetermined periods. Three-dimensional image processing or four-dimensional image processing is performed on the basis of a two-dimensional image and position information, the two-dimensional image being generated by making original image information, which is obtained by the ultrasonic transducers, two-dimensional in an ultrasonograph. The computer generates the images of a maximum diameter, a minimum diameter, and the difference between the maximum diameter and the minimum diameter for each measurement site in a carotid artery on the basis of the image processing result.
