Abstract
This study presents an innovative automatic system for detecting the intima-media complex of the far wall of the
common carotid artery by applying the snake techniques. Cohen's snake was modified and some criteria were added
for our applications. In addition, the oscillating problem of using snakes was solved by properly choosing the time
step from analysis of the frequency response of the filters. A time-diminishing gravity window, external forces, and
