An apparatus and method is provided for improving the quality of electrocardiogram (ECG) signals obtained from a patient undergoing magnetic resonance imaging (MRI) wherein the ECG signal has relatively high levels of noise or interference voltages induced on it by changing magnetic fields. The apparatus includes the arrangement of a differential amplifier, a prefilter, a signal limiter (SL) circuit and an intermediate amplifier with an integral low pas filter. The prefilter limits the rise time or high frequency component of the noise or interfering voltages induced on the ECG that are presented to the signal limiter.

Apparatus and method for removing magnetic resonance imaging-induced noise from ECG signals

A syringe adapter, which permits use of syringes of various types and sizes to be used with a front-loading injector, includes a piston extension and an adapter face plate. The piston extension includes structure for connecting the piston extension to a drive piston of the injector and a plunger of the syringe. The adapter face plate includes a mounting device for attaching the adapter face plate to an injector and a recess for receiving the distal flange of the syringe. The adapter face plate may also include locking pivot arms for releasably engaging the syringe flange.
