An Economical Multichannel Integrated Receiver/Reconstruction System for MRI

Abstract

A design is presented for a multichannel integrated receiver/reconstruction system for MRI that alleviates the concerns associated with commercial solutions regarding cost, scalability and the ability to access intermediate data. Up to 16 MR signals are sampled directly at RF, with digital down-conversion and image reconstruction performed by a single-chip field-programmable gate array (FPGA). Imaging researchers can readily access data from any point in the processing chain over a network, and the design can scale modularly in blocks of 8n or 16n channels
