The signal acquisition number is related to the computational complexity during signal analysis in MR fingerprinting. In this study, we develop a contour area index and demonstrate a quantitative method to evaluate the mapping precision under different signal acquisition numbers. It has potential in evaluating different RF excitation schemes in MR fingerprinting.
