For dynamic studies, it is often desirable to adjust parameters in “real time” depending on decisions made by user-defined algorithms. We performed a modification to the software tool MatMRI to develop a method that allows changing on demand multiple MR sequence parameters. We present results of this new method when applied to the modification of sequence parameters for MR-Acoustic Radiation Force Imaging. Our results demonstrate that it is feasible to reprogram MR sequence parameters dynamically using existing technology for the control of scanners.
