摘要:
A functional image creating method and a functional image creating apparatus, each enabling rendering of an activated region, are provided. A phase difference image PDr(x) is created using a complex image Ãr(x) created from an MR signal in an inactive state and a complex image Ã'r(x) obtained by filtering the complex image Ãr(x). A phase difference image PDa(x) is created using a complex image Ãa(x) created from an MR signal in an active state and a complex image Ã'a(x) obtained by filtering the complex image Ãa(x). Function signal images diff1(x) and diff2(x) are created using the phase difference images PDr(x) and PDa(x), respectively. A magnitude image Mr(x), a magnitude image Ma(x), a standard image, or a morphological image I(x) is masked with the function signal image diff1(x) or diff2(x), thereby a function image I'(x) with an activated region rendered is created.
