| Abstract: | A 2D-Thick-COBRA based detector with 10 × 10 cm2 active area operating in Ne/CH4 (95/5) flow mode, was applied to X-ray Computed Tomography (CT). The CT system is based on a third generation scanner with the object motion provided by a stepper motor. Multi-slice acquisitions of a Poly(methyl methacrylate) phantom and of a sea snail were done and the cross-sectional images were used to perform tri-dimensional (3D) visualization of the objects. Both kind of images (cross-sectional and 3D) are presented. Cross-sectional images using energy intervals of the spectrum are shown. Also, a simulation study of the influence of discharges (intrinsic to the MicroPatterned Gaseous Detector operation) in the resulting cross-sectional image was done and presented, showing no significant influence on the final image |
