Following the advancement of the Positron Emission Tomography (PET), a novel technique
emerged which takes advantage of the gamma quanta emitted, in some cases, after the β+ …

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) is the most sensitive in vivo molecular imaging
technique available. Small animal PET has been widely used in studying pharmaceutical …

Application of Compton cameras to nuclear medicine or small animal imaging is a
challenging subject. A major issue is insufficient spatial resolutions of the existing Compton …

In this article, we propose a novel image reconstruction technique for three-gamma (3-)
imaging systems that aims at reaching high image quality with a low statistics. The proposed …

Positrons are widely used in molecular imaging through the Positron Emission Tomography
(PET) imaging technique. However PET only reconstruct the distribution of the positron …

Compton cameras can offer advantages over gamma cameras for some applications, since
they are well suited for multitracer imaging and for imaging high-energy radiotracers, such …

Organometallic liquids provide good properties for ionization detectors. TriMethyl Bismuth
(TMBi) has been proposed as a detector medium with charge and Cherenkov photon …

We report the studies and optimization of scintillation light measurements in an updated
version of the XEMIS1 prototype for the development of the XEMIS2 camera. A novel …

This contribution addresses the problem of image reconstruction of radioactivity distribution
for which the available information arises from several classes of data, each associated with …
