ULTRASONIC IMAGING APPARATUS

摘要

PROBLEM TO BE SOLVED: To reduce speed of breakage of a microbubble contrast agent due to radiation of ultrasonic waves in ultrasonic imaging to the heart using a microbubble contrast agent. SOLUTION: The ultrasonic energy in shooting imaging frames is varied by frame. The contrast of images is thus increased, and the contrast can be maintained. COPYRIGHT: (C)2009,JPO&INPIT
