Gamma camera scanning systems that permit the bedside assessment of critically ill patients. Some systems are configured with the detector, detector stand, and data-processing console integrated into a single-powered, wheeled unit; other systems include the data-processing console in a separate unit, which is also mounted on wheels and interconnected by coaxial or fiberoptic cable to the detector unit. The operation and image acquisition process in the mobile systems are similar to those in the stationary systems; most mobile systems can obtain only planar images, but some have single-photon emission capabilities. Mobile gamma camera scanning systems are used mostly for the assessment of cardiac function and perfusion in patients with myocardial infarction and in other critically ill patients.
