A procedure for gated single-photon emission transaxial tomography of the
cardiac blood pool using a commercially available rotating camera and a
computer is described. During image acquisition, the end- diastolic and
end-systolic frames are retained after each of the 16 angular steps of the
rotation of the camera around the anterior side of the patient's chest.
Complete acquisition takes 25 minutes; 10 more minutes are required for the
reconstruction and processing of the sections. One set of images is
oriented transaxially; the other set includes vertical sections obtained by
rotation around a vertical axis passing through the center of the left
ventricular cavity. Results from the planar and tomographic examinations
were in good agreement for most of the 18 patients who underwent both
studies, although more inferior abnormalities were detected with
tomography.
