PROBLEM TO BE SOLVED: To automatically set a parameter for filter processing to a nuclear medical image. SOLUTION: Signals from gamma camera 11,... are transmitted to a data collecting memory 31 to simultaneously collect the image of the whole area and the image within an interested area. The image within the interested area is two-dimensionally Fourier-transformed, and the frequency distribution every frequency is determined from the data after Fourier transformation by a power spectrum calculator 33. Cutoff frequency is judged from the distribution by a cutoff frequency judging equipment 34, and the parameter of a filter used in a filter processing device 36 is determined. |
