The history of Compton cameras began with the detection of radiation sources originally for
applications in astronomy. A Compton camera is a promising γ-ray detector that operates in …

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 …

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 …

Positron-emission tomography (PET) and single-photon-emission computed tomography
(SPECT) are well-established nuclear-medicine imaging methods used in modern medical …

Positron emission tomography (PET) plays an increasingly important role in research and
clinical applications, catalysed by remarkable technical advances and a growing …

X-ray and gamma-ray imaging are technologies with several applications in nuclear
medicine, homeland security, and high-energy astrophysics. However, it is generally difficult …

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 …

For radiological diagnosis and radionuclide therapy, X-ray and gamma-ray imaging
technologies are essential. Single-photon emission tomography (SPECT) and positron …

Boron neutron capture therapy (BNCT) is a high-dose-intensive radiation therapy that has
gained popularity due to advancements in accelerator neutron sources. To determine the …

In internal 131I therapy for thyroid cancer, a decision to continue treatment is made by
comparing 131I scintigraphy and [18F] FDG-PET. However, with current SPECT and PET …
