Analytical reconstruction formula with efficient implementation for a modality of Compton Scattering Tomography with translational geometry

In this paper, we address an alternative formulation for the exact inverse formula of the Radon transform on circle arcs arising in a modality of Compton Scattering Tomography in translational geometry proposed by Webber and Miller (Inverse Problems …

On a three-dimensional Compton scattering tomography system with fixed source

Compton scatter tomography is an emerging technique with attractive applications in several fields in imaging such as non-destructive testing and medical scanning. In this paper, we introduce a novel modality in three dimensions with a fixed source …

Analytic Inversion of a Radon Transform on Double Circular Arcs With Applications in Compton Scattering Tomography

In this work we introduce a new Radon transform which arises from a new modality of Compton Scattering Tomography (CST). This new system is made of a single detector rotating around a fixed source. Unlike some previous CST, no collimator is used at …

On 3D imaging systems based on scattered ionizing radiation

The use of scattered radiation for tomographic reconstruction continues to be a current challenge for designing future imaging systems. In the energy range of X and gamma rays used for biomedical imaging and non- destructive evaluation, Compton …

Compton scattering imaging system with two scanning configurations

The judicious use of Compton scattered radiation continues to be a relevant challenge for the future of tomographic imaging. In this context, a new modality of Compton scattering tomography has been recently proposed. This new system has the …

A new bi-imaging NDT system for simultaneous recovery of attenuation and electronic density maps

Computed Tomography is a widely used imaging technique for non-destructive testing and evaluation in industry. Tomographic modalities exploit only primary radiation, which is non-deviated but attenuated radiation going through matter. However, in the …

A new transmission Compton scattering tomography

In Transmission Compton Scatter Tomography, an object is scanned to reconstruct a map of its electronic density. Data recorded consist of scattered photons and are modeled by a Radon transform on a specific manifold that depends on the setup used. …

Scattering imaging system with dual configuration

Wisely exploiting scattered radiation, considered as noise until now, for image purpose is one of relevant techniques for emerging tomographic imaging. In this work we propose a new concept of Compton Scattering Tomography (CST) based on a fixed …
