ABSTRACT
Methods have been developed for on-line computer enhancement of a scintillation camera's myocardial images and for a graphical presentation showing relative thallium-201 activity in the myocardium. Enhancement uses fast Fourier transform techniques. The methods have been applied to multiple images obtained after stress and 45 hr rest. Patients with myocardial infarction and/or transient ischemia were evaluated and typical examples are presented.
