| 内容記述 | Combined PET-CT scanner that simultaneously reveals both PET and CT images within the body can indicate accurate fusion image of PET and CT image. We intended to measure the auto activation acitivity using PET-CT for the purpose of evaluating the accuracy of a superimpose method which we developed to desplay fusion image of the auto activation image of dedicated PET and CT planning image for HIMAC therapy. Malignant melanoma of the orbit, maxillary sinus cancer, lung cancer, pancreas cancer, recurrencr of rectal cancer, bone and soft tissue cancer, and prostate cancer were studied using PET-CT immediately after C-12 ion beam irradiation. Dedicated PET measurement was also done at another day for comparison fusion accuracy with each other. 71.4% of our cases showed good correspondence between PET-CT and dedicated PET fusion images. The orbital tumor showed some difference of each other, because FOV of planning CT for the orbital tumor was so narrow that the fitting algorithm tended to cause some errors. The maxillary sinus cancer showed also some difference between PET-CT and dedicated PET fusion images. Head position of the case at PET-CT measurement differed from that of planning CT, and the fusion images of the two studies differed each other. For clinical purpose, it seems to be better to evaluate the auto acitivity distribution that fused on planning CT. But, PET-CT measurement is very simple and easy to get fusion images. |
