Patent ID: 8199994

Claim:
A method comprising: receiving digital pixel data corresponding to one or more M-Mode images depicting at least a portion of an anatomical part; selecting a plurality of columns in said digital pixel data associated with a plurality of sample times; generating an alignment map by aligning said plurality of columns such that corresponding tissue layers match; constructing one or more motion curves using said alignment map, wherein said motion curves represent a motion pattern in said digital pixel data corresponding to said M-Mode images, said motion pattern separated from tissue layers identified in said alignment map; outputting said one or more motion curves; wrapping, based on the alignment map, a plurality of aligned columns and generating a synthetic image in which tissues are aligned and show no vertical motion; generating, based on the synthetic image, a tissue layers representation that is motion independent; and computing the generated tissue layers representation as a vector of scalars, wherein each vector correspond to a median or an average gray level along row of pixels in the synthetic image.
