AUTOMATIC IDENTIFICATION OF THE LONG AXIS OF THE LEFT VENTRICLE FROM NUCLEAR MEDICINE SPECT DATA FOR USE IN MYOCARDIAL PERFUSION STUDIES |
摘要 |
The long axis of the left ventricle is automatically identified by identifying, and correlating, local minima and maxima in images of slices of the left ventricle. Initially, the left ventricle is identified within a representative transverse slice of the left ventricle. The centerline of this slice is automatically computed and used as a reorientation axis, along which another (sagittal) slice of the left ventricle is reconstructed. The centerline of this sagittal slice is automatically computed, and is the long axis of the left ventricle. The accuracy of this identification is confirmed by reconstructing oblique transverse slices of the left ventricle and verifying that their centers are coincident. |
