Abstract
A nuclear medial diagnosis apparatus is used for performing diagnosis by administering a medicine marked with a radioactive isotope into an examinee and by using an image obtained by detecting gamma rays emitted from a particular organ or tumor where the medicine is accumulated. An image (an image created by an image creation unit) is created by a signal (a signal as an output from a radiation detector) corresponding to the energy of the gamma ray detected by a radiation detector. The image includes a contamination component attributed to gamma scattering in the radiation detector. An image correction operation unit performs a convolution operation to obtain a contamination image. The contamination image is subtracted by a corrected image creation unit. Thus, it is possible to prevent image degradation by the gamma ray scattering in the radiation detector.
