ECG-gated emission computed tomography of the cardiac blood pool. 
ECG-gated cross-sectional images of the cardiac blood pool were produced using a specially constructed emission computed tomographic scanner.  A pair of large-field-of-view cameras were mounted in opposition in a gantry that rotates 360 degrees about the patient.  The coordinates of each detected event, the output of a physiological synchronizer, and the position of the camera heads were input to a dedicated minicomputer which was used to produce the images.  Display as a movie permitted evaluation of regional and global wall motion in cross section without the disadvantages of superimposed blood pools as obtained in nontomographic views.
