Valve assessment from medical diagnostic imaging data

A method for assessing heart valve operation with medical diagnostic imaging data, the method comprising:

• for parameterizing motion of both aortic and mitral valves:
• automatically determining, with a processor, a first location of a heart valve from application of the medical diagnostic imaging data to a global location model, the first location being determined as a global heart valve position of the overall heart valve within a volume represented by the medical diagnostic imaging data, and the global location model being a first machine-trained statistical classifier;
• determining, with the processor applying a second machine-trained statistical classifier, a second location of an anatomical landmark of the heart valve relative to the heart valve, the determining of the second location being a function of the determined first location of the global heart valve position;
• determining, with the processor applying a third machine-trained statistical classifier, a surface of the heart valve as a function of the determined second location of the landmark, the surface representing a geometry of the heart valve itself;
• performing morphological quantification of a valve as a function of the motion of the surfaces of both the aortic and mitral valves, the performing comprising calculating a geometric value characterizing the valve;
• and
• displaying an image, the image being a function of the geometric value.
