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 …
Computed tomography has been widely used in biomedical and industrial applications. The well-known filtered back-projection algorithm, probably the most used reconstruction technique, fails when the angular range used for data acquisition is not …
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. This new modality, called circular CST (CCST), allows to register a complete …
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 …
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. …
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 …
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 circle passing through the source. That is why the new modality is named …
