PROBLEM TO BE SOLVED: To provide a PET (Positron Emission computed Tomography)-CT (Computed Tomography) apparatus and an image processing apparatus capable of giving suitable information for specifying a target volume to a radiotherapy planner.SOLUTION: A PET-CT apparatus includes: an image reconfiguration part; an image generating part; and a display control part. The image reconfiguration part reconfigures a breath-hold CT image from a projection data collected in the breath-holding state by an X-ray CT scanner, and reconfigures a breath-free PET image from a projection data collected in the breath-free state by a PET scanner. The image generation part generates a breath-free PET image already subjected to deconvolution by deconvoluting the breath-free PET image by spatial resolution. The display control part displays the breath-holding CT image and the deconvoluted breath-free PET image on a display part. |
