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 architect… Show more
