MRI Simulations for Frequency Swept Pulse Sequences
The Garwood group develops novel frequency swept pulse sequences for magnetic resonance imaging. Because it is very difficult to write down closed-form descriptions of the sequences, due to relaxation and varying physical properties, simulation plays an important part of understanding the behavior of the spins and validating reconstruction techniques. In addition, new reconstruction methods are becoming more and more computationally intense, as they move away from inverting Fourier approximations to the physical system, and toward inverting a more accurate physical model. These researchers are simulating entire pulse sequences on three-dimensional volumes. Applying MSI resources allows the researchers to perform more accurate simulations of new pulse sequences and tackle more difficult inversion problems.
