Assessment of radionuclide angiocardiograms using color/time images.
Color images obtained directly from the CRT display of a digital computer were used to assess the passage of radionuclides through the heart. Following separation of the right and left heart images, the former was recorded as blue and the latter as red, after which a composite image of the entire heart was generated. A cardiac chamber or greater vessel may be filled during both color/time phases if an intracardiac shunt is present. On the composite image, these overlapping areas appear as either the complementary color or white.
