ULTRASONIC DIAGNOSTIC DEVICE, IMAGE DISPLAY METHOD, AND IMAGE PROCESSING DEVICE

摘要

The present invention increases the visibility of the minute structure of blood vessels and bloodflow. This embodiment of an ultrasonic diagnostic device is equipped with an ultrasonic probe, an operation section, a signal generating unit, a first wall filter, a second wall filter, a greatest value holding computation processing unit, and a display unit. By means of ultrasonic waves, a scanning unit scans the interior of a subject body to which a contrast agent has been administered. The signal generating unit generates an orthogonal detection signal on the basis of the received signal output from the scanning unit, and outputs a packet signal. The first wall filter has a pass band corresponding to the bloodflow component contained in the packet signal. The second wall filter has a pass band corresponding to the bloodflow component and a tissue perfusion component contained in the packet signal. The greatest value holding computation processing unit applies a greatest value holding computation process to a first image corresponding to the output of the first wall filter. The display unit displays the first image subjected to the greatest value holding computation process, and a second image corresponding to the output of the second wall filter.
