Magnetic resonance scanner with wireless transmission of signals

[0021]The wireless concept to which the features of the present invention apply is based on upconversion of the RF (Larmor) frequency signals to microwave frequencies and transmission from local coils located in the patient blanket to microwave antennas located on the bore of the scanner. The combination of transmit and receive antennas on the patient and bore respectively constitutes a MIMO (Multiple Input / Multiple Output) system that allows individual signals from the patient antennas to be resolved. A wireless system greatly enhances the utility of MRI scanners by removing the requirement for cable connections to patient coils and gives rise to significant work flow benefits from eliminating the need to sterilize, connect and disconnect the cables. With substantially no reduction of bore size, an increased coil density above the current norms may be achieved, as well as improving scanner workflow. The present invention relates to the bore tube for use in the system described above
