Abstract
By using the high-resolution and pinhole collimators collectively in conjunction with a scintillation camera, one is able to obtain detailed scintiphotos of an anatomical area of interest. The pinhole collimator is especially important when visualizing small organs since it creates a magnified image with increased effective resolution. Because of the magnification or optical gain of the pinhole collimator, we are able to obtain images of children’s hips, thyroids, magnified posterior fossa scans, etc.
