Ultrasonic diagnostic apparatus

摘要

The present invention provides an ultrasonic diagnostic apparatus that is capable of displaying an elastic image, enabling an accurate and easy identification of tissue characteristics of a diagnostic part. Elasticity data regarding a test object is obtained based on a received signal of an ultrasonic probe, and an elastic image representing a distribution of the elasticity data of the test object is generated. A display mode setting means sets a display mode of the elastic image in such a manner that a different tissue can be identified based on a value of the elasticity data. In this case, the display mode is differentiated by the value of the elasticity data within one tissue. With this configuration, the tissue characteristics of the diagnostic part are identified by the elasticity data, and displayed in a different display mode, thereby displaying an elastic image identifiable accurately and easily.

主权项

1. An ultrasonic diagnostic apparatus comprising:
an ultrasonic probe configured to transmit an ultrasonic wave to, and receive an ultrasonic wave from, a test object, a computer including at least one processor, to effect operations including:
obtaining elasticity data regarding the test object, based on a received signal of the ultrasonic probe,generating an elastic image showing a distribution of the elasticity data of the test object,setting a display mode of the elastic image, in order that different types of tissue of the test object becomes individually identifiable based on a value of the elasticity data,identifying predetermined degeneration types within one tissue type according to the value of the elasticity data, and setting different display modes corresponding to the degeneration types with one tissue type, andseparating as a different elasticity data range, an area where the elasticity data ranges corresponding to at least two degeneration types are overlapping elasticity data ranges, and imparting different color information to the area.
