7T MRI: RF Systems and Concepts
New Tools for Ultra-High Field MRI
Our research group develops multichannel transmit systems for use in ultra-high field MRI systems to facilitate imaging of large volumes in the human body. We aim to provide tools that allow clinicians to make use of the full potential of ultra-high field MRI.
The work of the group can be divided into two parts: Hardware and Concepts.
On the hardware side, we work on the multi-channel transmit systems, including modulators, high power RF amplifiers, RF supervision hardware, transmit/receive switches, as well as RF arrays.
On the concepts side, we work on improving the use of the hardware, for example by introducing improved compression algorithms for the data fed into RF supervision hardware.
