Abstract
A downhole logging tool includes a radiation generation source operable to emit radiation into a formation surrounding the tool and a radiation detector operable to detect backscattered radiation from the formation surrounding the tool. The tool also includes a sleeve positioned around the radiation generation source, the sleeve including at least one aperture for forming a pathway for a radiation beam, emitted from the radiation generation source, to enter the formation, the sleeve being rotatable about an axis of the tool to change a position of the aperture to distinctly inspect different regions of the formation.
