PSUdoMRI Simulator

PSUdoMRI Simulator

Christopher M. Collins

PSUdoMRI is an MRI simulator developed to accurately predict how realistic distributions of the electromagnetic fields used in MRI (DC, switched gradients, and radiofrequency) affect the MR images for arbitrary MRI pulse sequences. PSUdoMRI is capable of considering multiple RF coils in transmission and in reception, considering correlated noise between RF channels, and calculating the SAR distribution throughout the sample for arbitrary pulse sequences or field distributions. Simple Matlab GUI's allow for creation of some sample sequences and some simple reconstructions, and some sample field and tissue distribtuions are provided, but the simulation engine is capable of considering any sequence, field, or sample geometry that is arranged in the proper format, as described in the manual.
