### Device Description:
The MEDRAD MRXperion MR Injection System is a software-controlled medical device used for the administration of intravenous MR contrast media and saline into the human vascular system for diagnostic studies in magnetic resonance imaging (MRI) procedures. Commonly referred to as an automated injection system, it is designed to allow a user to fill disposable syringes and then to perform an injection with a user-programmed volume and flow rate.
The MEDRAD MRXperion MR Injector consists of two basic modules: a Scan Room Unit (SRU) and a Control Room Unit (CRU).
The SRU is comprised of an integral injector head, base assembly, pedestal, and a power supply.
- The injector head of the SRU physically performs the injection. .
- . The base assembly functions as the interface between the CRU, the injector head, and the SRU power supply.
- . The injector head and base are located on a pedestal is designed with locking casters to allow the SRU to be moved when not connected to a patient.
- . To power the base assembly, power is received from the AC mains and is converted to DC voltage by the SRU power supply.
The CRU consists of an All-in-One Computer (AlOC), pod, their dedicated power supplies, mechanical stand, and an optional hand switch.
- The AIOC provides a platform for the graphical user interface for the injector as well as ● the optional informatics applications. From the AIOC, an operator can use the touchscreen display to manage protocols, arm and disarm the injector, review injection realtime progress/feedback and history, access eGFR and patient Weight-Based Dosing calculators, and set system configuration options. The operator can also use the features of the optional informatics device from the AIOC.
- The pod provides injection start and stop functionality and contains the safety controls . for the CRU.
- . To power the AIOC and pod, each component receives AC mains power from its own dedicated off-the-shelf power supply.
- The AIOC and pod are mounted on a desk top mechanical stand.
- . An optional hand switch gives the operator an additional means to start, hold, and stop an injection from the Control Room. The hand switch contains a light that identifies the state of the injector.
