MRI Modules:SYSSIM

MRI scanner simulator predicts realistic EM field effects on MR images for arbitrary pulse sequences.

Contents	MRI scanner simulator predicts realistic EM field effects on MR images for arbitrary pulse sequences.  Generates simulated MR images with realistic signal, contrast, noise, and SAR values considering B0 and fields from both transmit and receive arrays. SYSSIM has been developed in colloboration with Prof. Christopher Collins from NYU School of Medicine.
Applications	Optimization of pulse sequences to overcome or compensate for imperfections in the field distributions due to field/tissue interactions (e.g. implants or tumors) or design constrains. Enables engineers, physicists or radiologists without an MRI scanner to simulate the scanner for TX, RX and imaging performance.
Characteristics	Calculates k-space, signal & noise (SNR), time-average SAR distribution and resulting MRI images for user-defined reconstruction techniques based on. B1+/- and E fields (RF coils), gradient fields, and Bo field distributions from Sim4Life. Tissue geometry with electrical properties and MR properties (T1, T2, proton density, chemical shift,…etc.) including IT’IS ViP models. MR pulse sequences (GRE, SE, EPI) and sequence parameters (pulse shape, duration, flip angles, TE, TR, etc.)
