title: Use of the modulation transfer function in comparing the visual outcome units of gamma camera.
abstract: Modulation transfer function (MTF) was used in comparing the visual outcome units of gamma camera. Polaroid camera system and Micro Dot imager were studied using Polaroid film type 105 positive/negative and Kodak SO-179 X-ray film. It was proved that resolution in the Micro Dot imager is better than in the Polaroid camera system used, especially near the surface of the measuring object.
