Abstract
In a nuclear magnetic resonance imaging device, a pulse sequence is selected and a variance or standard deviation of a calculated image for T1, T2, .rho. is determined as a function of scan parameters from the theoretical equation of signal intensity in the pulse sequence and the variance in the values for T1, T2, .rho. to be measured and the original image. Scan parameters, with which the total sum of variance or standard deviation of the calculated image takes a minimum value, are determined as optimum values. An image is obtained from the optimum scan parameters to obtain a plurality of original images. A calculated image for T1, T2, .rho. is determined, based on the original images, whereby a calculated image of high quality is simultaneously obtained.
