The amount of radiation a patient receives in a typical nuclear medicine scan tends to be very low. The original gamma camera was developed in the 1950s by American engineer and physicist Hal Anger (1920-2005) 3. Each event is located using information from all the PM tubes and finally the position circuitry processes this information and can locate the point of interaction to within 2-3 mm.
