The aim of our research is to establish a virtual educational program of MR imaging technique with a computer-based simulation system. A fast simulation method of MR imaging is required for efficient learning of the relationship between imaging parameter settings and the generated MR images. In our research, MRI signal intensity equations are applied for fast MR imaging. Our previous research evaluated a T2 estimation method and simulation accuracy for spin echo pulse sequence. This time, the study shows an evaluation of simulation accuracy for SPGR sequence and IR sequence. Also, T1 is estimated by using image data of SPGR sequence. The T2 estimation method used is the same as our previous research. Results showed that an effective simulation of MR imaging is possible with the similar imaging parameter settings applied to real image data for T1 estimation. On the other hand, large simulation error of the IR sequence is obtained.
