Innovative RF coil helps deliver highly detailed 7.0T MRI

Glasgow-based product design consultancy Wideblue has participated in a project to develop next generation 7.0T MRI in order to provide new insights in brain disease research, assisting its client MR CoilTech to complete the first trial of high density radiofrequency (RF) head coil technology at the University of California. Wideblue ceo Russell Overend said: “When completed, the project will break through barriers in the field of brain disease research by introducing unprecedented levels of detail in brain imaging, which could lead to innovative new treatments.”

The head coil design utilises 16-channel transmit and 96-channel receive RF architecture. Wideblue says the prototype head coil combines with the next generation 7.0T scanner capabilities to enable high resolution full brain imaging to support studies of the cerebral cortex at an unprecedented microscale resolution, boosting image resolution by a factor of 20 over current 7.0T MRI. The head coil had to fit into an extremely compact space – which posed challenges from a design and electronics point of view – while still allowing routine scanning and a large visual field for neuroscientists to carry out functional MRI studies.

MR CoilTech director Dr Shajan Gunamony said: “We are delighted with the work Wideblue did on the CAD design of the prototype and with excellent initial results. It allowed us to meet the deadline for an important abstract submission.”
