Abstract
In a method for estimating an orientation of a cardiac long axis from corresponding early frame and late frame images implemented in a computerized processor, a bounding box of the myocardium is defined in the late frame image and the bounding box is applied to the early frame image. A main axis of the image of the early frame within the bounding box is estimated, and the image of the early frame is oriented according to the estimated main axis. A main axis of the image of the late frame within the bounding box is also estimated, and the late frame image is reoriented according to the estimated main axis. The estimated main axis of the early frame to the estimated main axis of the late frame are compared, and in attribute of the comparison result is made available as an output from the processor.
