ABSTRACT:
The method and apparatus of operating a positron emission tomography camera for measuring concentrations of positron emitting radioisotopes which measures radiation from a patient including true counts, scatter counts and random counts through an energy acceptance window in which the camera has a maximum camera transfer capability of measuring counts. The method and apparatus includes measuring the total counts of radiation and varying the energy acceptance window to accept the total counts available at the maximum camera transfer capability thereby minimizing the random and scattered counts and maximizing the true counts. The method further includes injecting an amount of radiation into the patient sufficient to initially saturate the maximum camera transfer capability. The energy acceptance window is varied by the measurement of total counts.
