This illustrates an Anger gamma camera with two camera heads mounted on a gantry ring manufactured by Trionix. This allows the technologist to position the patient on an imaging table between the detector heads and to acquire data for images while the detectors circle the patient. This is called SPECT imaging which is an abbreviation for Single Photon Emission Computed Tomography. This is to disinguish it from another nuclear medicine imaging technique called PET or Positron Emission Tomography which is another story altogether. This imaging technique is analogous to the radiographic imaging technique of CT or computerized tomography. The computer reconstructed images allow the viewer to see "depth" in the organ or tissue of interest. The best and simplest comparison to this is to think of the organ as a loaf of sliced bread and the images from the computer allow you to view the organ one "slice" at a time. Back
