PROBLEM TO BE SOLVED: To prevent errors due to corollary from entering in identifying the corollary by stimulating a physiological process in a patient by means of a stimulus function with an autocorrelation, obtaining a nuclear magnetic resonance signal resolved timewise and locally, and proving change in the activity locally resolved inside the patient by means of the time correlation with the stimulus function. SOLUTION: The pulse sequence for the excitation and read-out of nuclear magnetic resonance signals is performed mutually independently from a stimulus function, which are both clock controlled through the central controlling and computing unit; however, for example, trigger control is not carried out for the pulse sequence by the stimulus function. On the basis of this pulse sequence, a low data set is obtained; and from this low data set, an image data set is obtained again by two dimensional Fourier transformation. A timewise progress characteristics of signals can be obtained for the low data matrix inside the image data matrix or for each data inside each bikecell. Then, a cross- correlation is performed with this signal progress characteristics and the stimulus function.
