Synopsis

Key requirements and possible strategies for a wireless radiofrequency (RF) signal chain comprising signal digitization, data compression and different wireless transmission technologies are presented. Current advances related to wireless receive coils are discussed, e.g. wireless control signals and clock synchronization to the MRI system. Furthermore, a perspective on wireless power delivery strategies for additional on-coil components is given, e.g. energy harvesting and wireless power transfer systems tested in the MR environment, complemented by considerations concerning the MR compatibility of components required for wireless RF coils.
