1. Surface coil receiver circuitry for receiving signals from an array of surface coils in a magnetic resonance system, said circuitry comprising:
- a receiver channel for each coil of said array of surface coils,means for preprocessing said received signals,said preprocessing means comprising means for converting said received signals to digital signals,means for multiplexing said preprocessed signals from said receiver channels,means for providing quadrature components only after the multiplexing by operating on said multiplexed preprocessed signals thereby minimizing the need to balance the circuitry to prevent reflections,display means,means for processing said quadrature components to provide image data, andmeans for using said image data to provide images on said display means.

Abstract
Receiver circuitry for a surface coil array used in magnetic resonance diagnostic systems, said circuitry minimizes reflections and thus relaxes the prior art necessity for balancing the individual receiver channel for each array by obtaining quadrature signals from the acquired signals in processing circuitry located as close as possible process-wise to the display equipment.
