My research focuses on MR hardware and simulation for low and ultrahigh field imaging, Dense Tx Arrays for brain imaging at 7 Tesla, novel single element coil designs, and the effects of intersubject variability on safety and pulse design.
Presently designing a dense Tx array with RF shim capabilities for brain imaging. Simulations are tailored to shed light on the tradeoff between increased degrees of freedom and field B1+ field inhomogeneity. The physical design will compromise between the difficulty of building such a coil (coupling, power constraints, etc.) and its ability to shim with realistic intersubject variability.
Also I?m considering a library of head models in silico and looking to quantify how different SAR and the B1 field can in the scanning environment.
