Der Einsatz von Individualschablonen bei der Dreifach-Beckenosteotomie
… examination contains an ap- and a faux profile x-ray projection and the measurement of the anterior center edge and lateral center edge angle. The system of the individual templates was developed jointly with the Helmholtz Institute of Aachen. The bone surface is scanned by a computed tomography …

The impact alteration of X-ray source subject projection geometry has on the ability to detect demineralisation in occlusal cavities using digital subtraction radiography: an in-vitro study
… to investigate in-vitro, whether alteration of X-ray source subject projection geometry affected the accuracy and reproducibility of DSR for detecting demineralisation in artificially created occlusal cavities. The discriminatory ability and reproducibility of a grading system for assessing …

Evaluating the influence of machine-specific DRR parameters on the accuracy of X-ray simulation and orthopaedic 2D-3D reconstruction
… (CT), to be derived from 2D modalities such as X-ray imaging. Thus, clinical interventions such as implant design and postoperative evaluation can be made more accessible, less expensive and, in some cases, the dose of ionising radiation to the patient can be reduced. State-of-the-art approaches …

Scattered radiation in cone beam computed tomography : analysis, quantification and compensation
… the so-called catheter laboratory conventional X-ray projection imaging is classically used. Particularly in cardio-vascular angiography and neuroradiology, so-called C-arm systems are used, enabling a flexible positioning of X-ray tube and detector. In the last years, these systems experienced …

Application of a High‑Resolution Computed Radiography System in Detecting an Iodinated X‑ray Contrast Agent: Small Animal Phantom Study
… contrast agents are used to increase the X‑ray detectability of zone of angiogenesis, and thus providing a means for tracking tumor growth.</p> <p>The overall objective of this project was to evaluate the performance of Kodak CR 7400, a high‑resolution compact computed radiography (CR) …
