Examination by echography greatly depends on the expertise and experience of the operator. If cross sections of internal organs are automatically recognized from the echogram, it is possible to provide a position feedback system for the operator, which may also act as a guidance system for inexperienced operators. We first divided an echogram into sub-regions and detected the position of the mitral valve by the analyzing brightness. Furthermore, combining this technique with an optical flow method, we elucidated the contract velocity of wall motion in eight radial regions by centering the mitral valve. Finally, we recognized a short-axis view of the heart by comparing the correlation of the velocity between specified regions. By adopting those algorithms, we realized the guidance for operation of probe to image the intended echograms.
