PROBLEM TO BE SOLVED: To provide a cerebral blood flow determination analysis program or the like, capable of performing brain image reconstitution without performing subtraction when using a split-dose method of twice or more number of times, avoiding dispersion in each operator in selection of a slice including a basal ganglia and in setting of ROI, preventing occurrence of dispersion in a determination image, and removing complexities for the operator. SOLUTION: Split-dose of twice or more of a tracer labeled by RI is applied to a subject brain, and each piece of projection data acquired by performing SPECT measurement, after each split-dose, are inputted. Then, a reconstructed image after each split-dose is acquired, based on each inputted piece of projection data, and each standard brain image is acquired by performing anatomical normalization on the reconstituted image, after each split-dose. Each determination image can be acquired by performing prescribed determination to each acquired standard brain image. When the reconstituted image is acquired, IBL method or ABL method is used. Lassen correction is performed on a SPECT image, after anatomical normalization. COPYRIGHT: (C)2006,JPO&NCIPI |
