Title:

ULTRASONIC DIAGNOSTIC DEVICE AND ULTRASONIC IMAGE DISPLAY METHOD

Document Type and Number:

WIPO Patent Application WO/2014/087919

Kind Code:

A1

Abstract:

According to the present invention, by disabling shadow processing of regions other than a region of interest, an attractive three-dimensional image can be formed even when the regions other than the region of interest are displayed in semi-transparent fashion. This ultrasonic diagnostic device is provided with a transmission unit for transmitting ultrasonic waves to a subject through use of an ultrasonic probe, a reception unit for receiving a reflected echo signal from the subject, a three-dimensional elastic image formation unit for performing shadow processing of elastic volume data which includes an elasticity coefficient based on the reflected echo signal and forming a three-dimensional elastic image by volume rendering, and an image display unit for displaying the three-dimensional elastic image, the three-dimensional elastic image formation unit performing volume rendering using an elastic opacity corresponding to the elasticity coefficient and disabling the shadow processing for portions having a predetermined elastic opacity.
