Digital simulation dramatically facilitates the
understanding and development of new MR imaging methods.
In this work, we optimized and improved our proposed
fast 3D parallel numerical MR simulation package 'MRiLab'
for incorporating many new challenging simulation
features including multiple RF transmitting and
receiving, motion simulation, etc. The spin model is
also extended to include multiple exchanging spin
compartments to create more realistic MR signal for
certain types of tissues with, for instance,
magnetization transfer (MT) modulation. This abstract
was aimed to demonstrate the feasibility of using MRiLab
for studying multiple types of MR experiments that
remain challenging for numerical simulation.
