Advanced Nuclear Medicine Equipments

Nuclear medicine uses special type of imaging devices which are gamma camera and single-photon emission-computed tomography (SPECT). The gamma camera, also called a scintillation camera, detects radioactive energy that is emitted from the patient's body and converts it into an image. The gamma camera does not emit any radiation. The gamma camera is composed of radiation detectors, called gamma camera heads. SPECT involves the rotation of the gamma camera heads around the patient's body to produce more detailed, three-dimensional images, while the PET scanner is a large machine with a round, doughnut shaped hole in the middle, similar to a CT or MRI unit.
