UMD: Gamma camera systems that produce cross-sectional slices of the in vivo distribution of an administered radiopharmaceutical in the body, acquired at various angles around the patient and displayed as a computer-reconstructed tomographic image. These systems typically include a mechanical gantry to support and rotate the camera head and collimators in a circular or elliptical orbit around the body. Systems with multiple camera heads and/or coincidence imaging capabilities are also available. Single photon emission tomography systems are mostly used for whole-body bone imaging, brain perfusion studies, and cardiac imaging.
