Claim Text:
1. A method for left ventricle epicardium estimation in medical diagnostic imaging, the method comprising: acquiring C-arm x-ray data representing a left ventricle of a patient over time; detecting an endocardium over time from the C-arm x-ray data; identifying, with a processor, at least one motion template from a library of motion templates, the identifying being based on a similarity of the endocardium over time detected from the C-arm x-ray data with an endocardium of the at least one motion template, wherein the similarity is calculated by calculating a difference between the endocardium detected from the C-arm x-ray data and the endocardium of each of the motion templates of the library at each of a plurality of heart cycle phases, averaging the differences over the heart cycle phases for each motion template, and identifying the at least one motion template as having a least of the average difference; calculating, with the processor, a deformation field as a function of a difference between the endocardium of the at least one motion template and the endocardium detected from the C-arm x-ray data; applying, with the processor, the deformation field to an epicardium represented by the at least one motion template; and displaying an image of the left ventricle of the patient, the image being a function of the epicardium as deformed by the applied deformation field.
