Title:
ULTRASONOGRAPHIC SYSTEM AND ULTRASONOGRAPHY
Document Type and Number:
WIPO Patent Application WO/2003/077765
Kind Code:
A1
Abstract:
An ultrasonographic system that transmits an ultrasonic pulse into a tissue of an organism, receives and analyzes its reflected wave, and creates a diagnostic ultrasonogram comprises an analyzing unit for measuring the back−scatter intensity of the scattering wave from the region of interest of the organism tissue by using the received reflected wave signal and determining the variation frequency of the back−scatter intensity so as to make it usable as diagnosis data.
