Abstract
An automatic selection system utilizes a computer which automatically localizes the heart and automatically selects the most suitable representative slice among a set of transverse slices, which are reconstructed from the myocardial SPECT projection data, for determination of the left ventricular oblique axis in 3-D space. An intensity profile, which consists of maximum counts of each slice and correlates to the radioactivity of the organs in the reconstructed volume, is analyzed. The heart's left ventricle is localized and the representative slice is selected based upon the local and global extrema of such profile.
