At 7T, commercial MRI systems are currently available with a maximum of 8-16 transmit channels and 32 receive channels. To explore the potential benefits of increasing these numbers, which have been predicted by prior experimental and simulation work, we have developed and installed 32-channel RF transmitter and 64-channel receiver upgrades for a standard 7T commercial MRI system. These additions have been fully integrated into the system in a way that they can be reliably employed for routine studies without requiring significant workflow modifications or special user training.
