Research Project: Development of radiofrequency (RF) coils and imaging techniques for TRASE imaging.
Project Details: The aim of this project is to develop a new type of low-cost MRI device, as featured in ‘Research Highlights’ in Nature in 2013. The are a number of possible research ddirections within this overall program. These include radiofrequency coil and electronics design, accelerated image reconstruction and magnet design.
TRASE (Transmit Array Spatial Encoding) is an alternative MRI encoding principle that operates entirely without the use of conventional B0 magnetic field gradients and so offers imaging with substantially simpler equipment. The key technical difference between this and previous radiofrequency (RF) encoding techniques is that the gradient of the phase of the RF field, rather than the magnitude, is exploited. This is a crucial distinction because high spatial resolution becomes practical as the encoding is performed progressively by a series of 180 degree refocusing pulses without excessive RF power requirements. Image resolution is proportional to phase gradient strength and echo train length, and was featured in ‘Research Highlights’ in Nature in 2013.
