Standard maximum co-scan range is system dependent Horizontal and vertical table positioning achieved using the motion control system on the front of the gantry The patient table is a table-on-rails design for full-body imaging of a patient. It supports 227 kilograms or 500 pounds and is positioned on a pedestal that slides on floor-mounted rails. The standard maximum co-scan range is system dependent. Horizontal and vertical table positioning can be achieved using the motion control system on the front of the gantry.2 Universal Physiological Measurement Module (UPMM) Located near pedestal end of the patient gantry Receptacle for the ECG electrodes Push button for changing ECG measurement mode Single connection for PET and CT cardiac gating External trigger device connection Moves with the patient   The Universal Physiological Measurement Module, or UPMM, is located near the pedestal end of the patient table. The UPMM provides the receptacle for the ECG electrodes and a push button for changing the ECG measurement mode. It provides a single connection point for PET and CT cardiac gating. The UPMM also provides a connection for an external trigger device. The UPMM moves with the patient, which promotes patient comfort and reduces the risk of lead entanglement. 3UPMM Components for Biograph mCT and Biograph Vision Hinged lid - closed when the UPMM is not in use Lead selector push button - push to change which two leads are used to generate the ECG signal ECG lead cable connector Respiratory trigger connector (not currently used)  External trigger connector View the text that corresponds to the number in the image.CalloutsHinged lidLead selector push button  ECG lead cable connector  Respiratory trigger connector  External trigger connector  For the Biograph mCT and Biograph Vision, the UPMM consists of a hinged lid containing the lead selector button which the operator pushes to change which two leads are used to generate the ECG signal.
