Image analysis of the heart action recorded with a high speed multicrystal gamma camera.

The use of a high speed scintillation gamma camera for recording and an adequate bolus injection technique during first pass of a radionuclide tracer provides significant information about the function of the heart chambers. The computer-stored information can be processed to get easy interpretable images and parameters for detailed diagnosis. With special procedures the statistical noise of the zones of the images with low count rates can be suppressed, allowing use of smaller quantities of radionuclide, thereby reducing radiation for the patient.
