Cardiac MRF is a unique MRF technique that requires a new dictionary for each acquisition to account for heart rate variability. Dictionary simulation presents a barrier for accessibility to cardiac MRF techniques due to the lack of tools at the scanner. To this end, Bloch simulation tools were developed on the Gadgetron platform to allow for online dictionary simulation and pattern matching reconstruction. Results between prior MATLAB implementations and Gadgetron implementation were in agreement. Future work in optimization may allow for data feedback from the scanner, reducing the need for additional scan time for accurate quantification of T1 and T2 maps.
