Ultrasonic diagnostic apparatus and ultrasonic diagnostic method

摘要

An ultrasonic diagnostic apparatus has an ultrasonic probe, a control unit, a basic image generating unit, a differential image generating unit, and a composite image generating unit. The control unit controls the ultrasonic probe so as to sequentially perform, every scanning line of scanning lines in a scanning region, a transmitting and receiving under a first transmitting/receiving condition, a second transmitting/receiving condition, and a third transmitting/receiving condition. The basic image generating unit generates a first image based on the first transmitting/receiving condition, a second image based on the second transmitting/receiving condition, and a third image based on the third transmitting/receiving condition. The differential image generating unit performs a differential processing based on the first image and the second image to generate a differential image. The composite image generating unit performs a composite processing based on the differential image and the third image to generate a composite image.

1. An ultrasonic diagnostic apparatus comprising:
an ultrasonic probe configured to transmit an ultrasonic pulse to a two-dimensional scanning region or a three-dimensional scanning region, and to receive an echo corresponding to the ultrasonic pulse as a received signal; a processor configured to:
control the ultrasonic probe so as to perform scanning by sequential scanning lines in the scanning region, and sequentially perform a transmitting and receiving under a first imaging condition and a transmitting and receiving under a second imaging condition which is different from the first imaging condition in a same cross-section;generate a first image obtained by processing the received signal under the first imaging condition and a second image obtained by processing the received signal under the second imaging condition, the first and second images being images in which signal intensity is expressed by brightness;perform a differential processing between the first image and the second image to generate a differential image; andperform a composite processing between the differential image output from the differential processing and a medical image to generate a composite image.
