1 1 Ultrasound Video Processing for Quantitative Analysis of Fetal Movements by means of organ tracking

2 2 Ultrasound Image Processing for Quantitative analysis of Fetal Movements – Ben-Zion Shaick and Leonid Yaroslavsky Block diagram of the experimental system. (a) The routine system is used for recording the US movies on a videocassate. (b) The recorded videocassate is passed to the experimental system for off-line digital image processing.
