Most imaging devices need patient support, usually a table or sometimes a stool. For upright MRI- or PET-systems the patient support could be a stool. Portable devices like ultrasound and mobile X-ray devices typically don't need patient support. However, devices like CT, MRI, and interventional X-ray scanners have motorized tables that often use one or two power supplies. Several factors determine the power needed for patient support, including the maximum patient weight, the material and weight of the support platform, and the required speed and accuracy of movement. For example, in CT scans during an exam, the speed of the patient support differs significantly depending on the number of detector slices, the body part being examined and the examination itself, and whether contrast media is implemented [1, 2].
