Simplified method for determining the modulation transfer function for the scintillation camera.
The modulation transfer function (MTF) has long been accepted as an index of scintillation camera system resolution, but the technique necessary for the derivation of the MTF has discouraged its widespread acceptance because of its tedious and time-consuming nature. We have shown that the generation of LSFs for input into computer programs for MTF generation can be accomplished very easily and in short periods of time by using a simplified method. Establishment of the validity of this simplified procedure should contribute to more widespread utilization of the MTF in routine quality control programs as a check for crystal deterioration, electronic circuitry degradation, and/or collimator damage.
