Scintillation camera data storage, processing and playback capabilities are becoming an important if not essential function of the modern nuclear medicine laboratory, both in routine service studies and in research. However, the high cost of current dedicated computers makes them relatively inaccessible to many laboratories. Polaroid film has long been the primary medium of image acquisition and storage, offering the advantages of an immediately available image. Mostly used with a 3-lens camera, where each tens is set on a different f-stop to compensate for the poor latitude of the film, the final copy consists of three minified images with a crude form of background subtraction at the high f-stops. The usefulness of Polaroid film used this way was greatest when spatial resolution was relatively poor, and data density was limited by the radiation dose delivered by the available radioisotopes.
