Compton imaging or Compton camera imaging has been studied well, but its advantages in
nuclear medicine and molecular imaging have not been demonstrated yet. Therefore, the …

We proposed a concept of whole gamma imaging (WGI) that utilizes all detectable gamma
rays for imaging. An additional detector ring, which is used as the scatterer, is inserted in the …

The use of real-time gamma imaging for cancer treatment in particle therapy is expected to
improve the accuracy of the treatment beam delivery. In this study, we demonstrated the …

We have been developing a medical imaging technique using a Compton camera. This
study evaluates the feasibility of clear imaging with 99m Tc and 18 F simultaneously, and …

Compton imaging exploits inelastic scattering, known as Compton scattering, using a
Compton camera consisting of a scatterer detector in the front layer and an absorber …

Compton-based prompt gamma (PG) imaging has been proposed for in vivo range
verification in proton therapy. However, several factors degrade the image quality of PG …

Proton therapy is a widely used and effective treatment for cancer. A high-dose
concentration of proton beam reduces damage to normal tissues. However, it also requires a …

Compton imaging is a gamma ray imaging technique that has many possible applications
including homeland security and medical imaging. Using the Compton scattering formula …

Radionuclide therapy (RNT) is an internal radiation therapy that can selectively damage
cancer cells. Recently, the use of alpha-emitting radionuclides was initiated in RNT owing to …

We have developed an electron-tracking Compton camera (ETCC) for medical use. Our
ETCC has a wide energy dynamic range (200–1300keV) and wide field of view (3sr), and …
