The pin‐hole collimator is used to improve spatial resolution and magnify areas of interest. The pin‐hole collimator has many applications in small animal veterinary scintigraphy. The principles of image formation for the pin‐hole and parallel hole collimators are reviewed. The effects of distance on resolution and sensitivity are presented for the pin‐hole and parallel hole collimators. Specific application of the pin‐hole and parallel hole collimators. Specific application of the pin‐hole collimator in veternary scintigraphy are discussed.
