Abstract

Based on software radio theory, this paper focuses on researching a direct conversion structure for the radio frequency (RF) receiver front-end and tries to apply this flexible receiver front-end in MRI receiving system. In particular, we look at the conventional architecture of RF receiver front-ends of MRI; present architecture of a direct conversion for RF receiver front-end of MRI; outline the key aspects of designing such multi-channel and multi-mode front-end systems. In addition, based on this architecture, a practical RF front-end receiving system of MRI is given. Two parts are included in this system; one is the conventional receiver front-end the other is the direct conversion design for RF receiver front-end of MRI.
