| Research Abstract |
The PET is excellent medical instrument for the early discovery of cancers. However, better imaging performance and lower dose to human body are required. So I hit on the idea to utilize the Compton scattering in the plastic scintillator to Time-of-Flight PET and I have carried out the basic experiments constructing the prototype detector. Though I can not obtain the world record for the time resolution, it is confirmed that the prototype detector can obtain the time resolution of 500~600 psec. Moreover, I recognized that the time resolution will go up suppressing the multiple Compton scattering if the size of the plastic scintillator becomes smaller.
