ULTRASONIC DIAGNOSTIC DEVICE

摘要

A body movement signal generation unit generates a body movement signal which varies in response to body movement of a test subject as a diagnosis subject on the basis of a reception signal corresponding to a monitoring reception beam obtained from a reception unit. A body movement monitoring unit determines the start time of a diagnosis-recommended period in which body movement is minimal by distinguishing between large and small body movements on the basis of the body movement signal obtained from the body movement signal generation unit. A control unit executes diagnostic processing from a start time for diagnosis. Through this configuration, it is possible to obtain stable diagnostic information in which the effect of heartbeats is low and that is preferably entirely unaffected by heartbeats.

主权项

1. An ultrasonic diagnostic device, comprising:
an ultrasonic probe, a transmission unit for controlling the probe to transmit an ultrasonic wave, a reception unit for obtaining a reception signal of the ultrasonic wave received by the probe, a body movement signal generation unit for generating a body movement signal which varies according to a body movement of a test subject based on a reception signal of the ultrasonic wave related to the test subject, and a body movement monitoring unit for determining start time of a diagnosis-recommended period in which the body movement is small by discriminating between large and small body movements based on the body movement signal, wherein: diagnosis processing is started from the start time, and a shear wave is generated in the test subject by the diagnosis processing to obtain diagnostic information on a tissue in the test subject.
