Abstract (in Japanese) (See Japanese page) 
(in English) The aim of this research is to evaluate a computer based simulation of MR imaging technique for education of radiological technologists. For efficient learning of MR imaging technique, iterative study with rapid simulation of various imaging parameters is effective to learn relationship between settings of imaging parameters and generated MR images. In the proposed method, MRI signal intensity equations are applied for fast simulation of MR imaging. Model parameters, such as distribution maps of T1 and T2 relaxation times of a target section, are required for the MR imaging simulation. This report shows estimation of T1 and T2, and evaluation of simulation accuracy. In this research, the evaluation is applied to a homogeneous phantom of CuSO4. Slice data of a spin echo pulse sequence, a spoiled gradient-recalled pulse sequence, and an inversion-recovery pulse sequence are used for parameter estimation and evaluation of simulation accuracy.
