Abstract
An apparatus and method for indicating locus of an ultrasonic probe configured to transmit and receive ultrasonic waves toward a part of a subject wherein a position or movement of the ultrasonic probe is detected, and a locus of the ultrasonic probe on an image of the part of the subject is indicated according to the detected position or movement.
Claims17
An ultrasonic diagnostic apparatus comprising:
- an ultrasonic probe configured to transmit and receive ultrasonic waves toward a part of a subject during scanning movement of the ultrasonic probe across a body surface of the subject;
- a detecting unit configured to repeatedly detect successive positions of the ultrasonic probe on the body surface during each of plural scanning movements of the ultrasonic probe and to generate for each scanning movement a respective locus mark indicating portions of the body surface scanned;
- a memory to store each locus mark for each scan;
- a signal processor configured to generate an ultrasonic image related to the part of the subject on the basis of an echo signal acquired by the ultrasonic probe;
- and
- a locus indicating unit, including a request device, configured to display each locus mark singularly, and upon activation of the request device, to display a composite image of a plurality of the locus marks stored in the memory, thereby to display a composite locus mark scanning image of scanning regions of the ultrasonic probe on the body surface of the subject.
