System and methods for cardiac cycle selection

Abstract

Methods and systems are provided for identifying cardiac cycles for evaluating left ventricle function using only image data. In one example, a method includes obtaining a sequence of medical image frames of a heart of a patient over a plurality of cardiac cycles, wherein each medical image frame depicts the same apical view of the heart, using a timing model to generate an output that is useable to label each frame of the sequence by cardiac cycle subphase and using the output to determine the suitability of each cardiac cycle for performing an automated measurement. The method may further include using the suitability of each cycle to determine if an automated measurement should be performed on each cycle, where automated measurements are performed on medical image frames corresponding to suitable cycles and automated measurements are not performed on medical image frames corresponding to unsuitable cycles.
