Progress in nuclear physics acquired during World War II has naturally led many scientists to
devote their research activities to the field of tomographic imaging techniques using ionizing …

Scatter coincidences contain hidden information about the activity distribution on the
positron emission tomography (PET) imaging system. However, in conventional …

A new modality of Compton scattering tomography (CST) is presented. This model is
composed of a fixed source and detectors placed on a fixed ring passing through the source …

Abstract In 1981 Cormack studied the Radon transform defined on a family of curves and
showed their inversion through their circular harmonic expansions. In this paper we propose …

We investigate the idealized mathematical model of single scatter in PET for a detector
system possessing excellent energy resolution. The model has the form of integral …

A new modality of Compton Scattering Tomography (CST) is presented. This model allows
image acquisition and reconstruction using a fixed source and detectors placed on a fixed …

The availability of high resolution, energy discriminating photon counting detectors should
make it possible to use Compton scattered photons to improve the diagnostic capability of …

The reconstructed electron density image quality is sensitive to the detector size and energy
resolution, which contribute to the blurring and noise in the image. This work evaluates …

A colon imaging capsule has been developed by Check-Cap Ltd (C-Scan® Cap). For the
procedure, the patient swallows a small amount of standard iodinated contrast agent. To …

Image-reconstruction with Compton-scattered photons is a nonlinear problem, because it
involves both the linear process of scattering and the exponential pre-and post-scatter …
