Abstract
Multiscale Motion Mapping ("Triple-M imaging") is a novel image- processing technology that combines multiscale optical-flow techniques, spline imaging, and comprehensive mathematical analysis in space and time. In contrary to Tissue Doppler Imaging or endocardial border-detection algorithms, the use of all the available grayscale information yields quantitative motion maps which are neither angle-dependent nor limited to endocardial visibility. This allows observation and quantitation of motion in every sector of the ultrasound image. The technique was applied to clinical ultrasound, after validation by a rotating phantom.
