Title:
ULTRASONOGRAPHIC DEVICE AND IMAGE PROCESSING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2006/123729
Kind Code:
A1
Abstract:
An ultrasonographic device includes means for transmitting/receiving an ultrasonic sound to/from an examinee and capturing a dynamic image of the examinee. The ultrasonographic device further includes: speckle measuring means for measuring a size and/or shape of a speckle appearing on each frame and smoothing means for smoothing image data of each frame according tot he measured speckle size and/or shape.
