ABSTRACT:
An ultrasonic diagnosing apparatus displays a modified C-mode image of the target of an object to be diagnosed by mechanically moving an ultrasonic probe around the target portion while electronically driving the probe to scan the target. The ultrasonic diagnosing apparatus comprises a circuit for setting a desired cross-section to be diagnosed in the B-mode image of the target while observing said B-mode image, a memory for storing the data of the cross-section set by the cross-section setting circuit, a function generator for converting the position data into a function signal for controlling the scanning of the target and the processing of an ultrasonic echo signal reflected therefrom, a signal processing device for processing the ultrasonic echo signal under control of the function signal, and a display means for displaying a modified C-mode image of the target.
