Title:
ULTRASONIC DIAGNOSTIC SYSTEM
Document Type and Number:
Japanese Patent JP3689095
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable evaluation of a blood perfusion region in a cardiac muscle with an image of cardiac muscle distribution by obtaining an exact image having reinforced luminosity through a contrast agent.
SOLUTION: An ultrasonic diagnostic system comprises means (20-23) to impart a drive pulse signal of electrical amount having a fundamental wave component of a desired excitation frequency to a probe (10), means (30,31,32a,32b) for generating an image data with respect to a non-fundamental wave component included in an echo signal coming from a probe (10) and the fundamental wave component, and means (33,35,36) to display the image data. For example, the non-fundamental wave component is extracted from the echo signal, and then a two-dimensional distribution data of moving speed of a reflective echo source is calculated to be displayed.
