Scattered radiation in cone beam computed tomography : analysis, quantification and compensation
… context, this thesis addresses the problem of scattered radiation. Because in CBCT with large area X-ray detectors the irradiated patient volume is substantially larger than in classical computed tomography, also the amount of scattered radiation reaching the detector is significantly larger …

Digital radiography: image acquisition and scattering reduction in x-ray imaging.
… and by developing a method to reduce the scatter contribution in mammography examinations using image post-processing techniques. During the CMOS X-ray detector product design phase, it is crucial to detect any short- comings that the detector might present. Image characterization …

Optimization of a High-Energy X-Ray Inline Phase Sensitive Imaging System for Diagnosis of Breast Cancer
… image quality involves the introduction of anti-scatter grids and operating the x-ray tubes at much lower x-ray energies as compared to the other radiography fields, both of which results in an increased radiation dose. The current method for providing higher image quality involves utilizing …
