ABSTRACT A new imaging principle for object reconstruction is proposed in Single Photon Emission Computer Tomography (SPECT) which
is widely used in nuclear medicine. The quality of SPECT images is largely affected by many adverse factors among which chiefly
Compton scattering of gamma rays. Recently we have proposed to exploit Compton scattered radiation to generate new data necessary for object reconstruction, instead of discarding it as usually done. This has led us to a new underlying imaging
principle based on the inversion of a generalized Radon transform. In this new three-dimensional reconstruction method both
signal to noise ratio and image quality are improved. Remarkably the complete data, collected at various angles of scattering, can be obtained by a motionless data taking gamma camera. Examples of object reconstruction are presented as illustrations.

    ABSTRACT: A new concept of gamma emission imaging based on the use of scattered radiation with a non collimated gamma camera is put forward. A few years ago, scattered radiation by Compton effect is shown to be capable to reconstruct a three dimensional object using a standard collimated gamma camera. To increase drastically in sensitivity, we propose now that data acquisition should be performed without collimation. We present this new image formation by scattered radiation via the properties of its Point Spread Functions (PSF). Comparison with the PSF in the presence of a collimator exhibits a striking image enhancement. We also present numerical simulations on image formation and reconstruction to support the attractiveness of this modality.

    ABSTRACT: A new modality in gamma-ray emission imaging, based on the use of scattered radiation detected with an uncollimated gamma camera, is put forward. Recently, we have shown that scattered radiation by Compton effect registered on a collimated gamma camera can be in principle used to reconstruct an object in three dimensions. To improve drastically the sensitivity of this process, we propose that data acquisition should be performed without mechanical collimation. As a first step, image formation in two dimensions is derived and validated by Monte Carlo simulations. Then, numerical reconstructions are presented to support the feasibility and attractiveness of this new concept.

    ABSTRACT: This paper presents a new dual-modality imaging principle using two recent results. The first one demonstrates the feasibility of reconstruction of a radioactive distribution from its Compton-scattered radiation. This may be regarded as a novel gamma-ray emission imaging principle. The second one shows the possibility to reconstruct the electronic density of a medium and its attenuation map from other Compton-scattered radiation emitted by an external gamma source and scattered in the medium. The required data for the two reconstructions are easily acquired from an energy and space measuring gamma camera under the form of scattered distribution images classified by their Compton-scattering angle. The usual motion of camera is no longer necessary and so all images needed for a three-dimensional reconstruction are recorded simultaneously. For non-immobile object, this is a decisive advantage
