Beschreibung
Zusammenfassung:	An improved magnetic resonance imaging (MRI) injection system exhibits decreased electromagnetic interference (EMI) and improved mobility. The injector apparatus of the injection system includes a head assembly with at least one drive piston and a base assembly including the motor control circuitry and drive motors necessary to control the injector. The electronics in the base assembly are designed to reduce EMI with the magnetic field of the MRI system by employing Faraday cages and various circuit design and filtering techniques. The head assembly of the injector apparatus may also include a hand switch for local control of the injector.
