Abstract
An edge between a tumor and a normal tissue is detected even when acoustic impedance and elasticity of those are not changed. An edge position of tissue is estimated by setting a plurality of estimation regions of an inspection object, detecting direction of motion of the inspection object within each estimation region, and computing the point of inflexion in the direction of motion. Moreover, these edge positions are overlapped on the cross-sectional images and thereby an operator can easily detect the edge lines.
Claims10
An ultrasonic apparatus, comprising:
- an ultrasonic cross-sectional image acquirer that acquires, on the time series basis, a plurality of frames of the ultrasonic cross-sectional images of an inspection object;
- a memory that stores said ultrasonic cross-sectional images of a plurality of frames acquired;
- a motion detector that extracts information about motions of each tissue within the ultrasonic cross-sectional images of a first frame by comparing the ultrasonic cross-sectional images of said first frame with ultrasonic cross-sectional images of a second frame read from said memory;
- an edge detector that detects an edge within said ultrasonic cross-sectional images on the basis of the information about motion detected with said motion detector;
- and
- a display that displays the edge detected with said edge detector overlapping on the ultrasonic cross-sectional images acquired with said ultrasonic cross-sectional image acquirer.
