ULTRASONIC DIAGNOSTIC IMAGING APPARATUS WITH CONTRAST AGENTS

摘要

PROBLEM TO BE SOLVED: To solve problems with the conventional image processing using contrast agents wherein, although it is effective for displaying a capillary vessel, it is not always suitable for displaying a region in which a large amount of blood quickly moves such as a ventricle, and also there is a demand toward further clear display of a thick blood vessel in the capillary vasoganglion. SOLUTION: This ultrasonic diagnostic apparatus includes: an ultrasonic converter probe having a means for transmitting an ultrasonic pulse to the inside of the body in which an ultrasonic contrast agent is injected and sending high and low energy ultrasonic pulses to receive an ultrasonic echo signal caused by pulse transmission; an inducing circuit responding to a physiological function for inducing high-energy ultrasonic pulse transmission; a contrast signal processor for processing an echo received in response to high-energy pulse transmission; a B-mode signal processor for processing an echo received in response to low-energy pulse transmission; and a display device for displaying an actual time B-mode image and an induced contrast agent image at the same time.
