The Dynamic Information Detecting of New M-Mode Echocardiogram Ultrasonic Images

LAN Qi-bin(School of Information and Technology,Xiehe College,Fujian Normal University,Fuzhou 350108,China)  
On analysis of new M-mode echocardiogram ultrasonic images and their edges,the study curbed noise through sub-linear gray-scale transformations,and enhanced images by expanding their dynamic range.Based on the use of linear search template,a semi-automatic detecting method of searching algorithm was proposed,which was proved quite effective in tracking the edges of echocardiogram.Carrying on the differential of dispersed position-time function,we obtained data of velocity field and acceleration field,providing significant diagnostic parameters for the clinical diagnosis of cardiovascular disease.
