Table 3:
Relative errors in relaxation times for different acquisition patterns when T1=1400ms and T2=50ms, which are values representative of myocardial tissue at 3T. Each row refers to a physical effect or system imperfection that was modeled when generating the ground truth cMRF signal timecourses but not modeled when matching to the dictionary.
