RF Coil Development
Radiofrequency (RF) coil development has been an active area of research within the CFMM for more than two decades. The primary focus of development has been on advancing technology with the aim to improve the image quality obtained from high-field MRI scanners, for both human and animal imaging. This includes the design, simulation, and fabrication of transmit coils that can provide high efficiency, low SAR, and a uniform field profile; for human imaging, this includes leveraging the parallel-transmit capabilities available on ultra-high field scanners. Receive-coil development is crucial to improving coil sensitivity, while commensurately improving patient comfort, line-of-sight, and overall work flow.

Award Value: Reduced Rate
The purpose of this project is for the scientific study and publication of radio frequency coils developed for the 7T and 9.4T MRI scanners. This includes the study of technical developments of human coils with higher SNR and/or attainable acceleration rates for neuroimaging, as well as their integration into the MRI system architecture with local SAR monitoring. Publications will result from each novel coil that is evaluated on the system, as well as the use of local SAR monitoring on the scanner, and the ability to use spatially selective RF pulses with these coils to benefit routine scanning of the brain for CFREF studies. The study of technical developments will also include animal coils developemed for the 9.4T scanner. These coils will allow for high-resolution anatomical and functional imaging for the study of healthy and diseased animal models.
t involves the scientific study and publication of the technical development of state-of-the-art hardware; this hardware improves image quality for the majority of CFREF and CFMM-funded studies being completed on the 7T and 9.4T. It involves collaboration of basic-scientists, physicists, and engineers to achieve this goal.
