Self-Determined Shot Geometry for Open-Configuration Portable X-ray CT

Open-configuration portable x-ray computed tomography (CT) is a technology that enables the volumetric inspections of regions interest on large parts. The open-configuration aspect CT allows it to be and applicable irregular parts are not conducive conventional booth setups or ring geometry. inherent problem with setup lack mechanical controls determine geometry between source, detector, part. As result, focus this paper prerequisite technique self-determine shot from itself. Additional difficulties pertaining self-determined there nine system unknowns for every as compared has total. To address these problems, presented here three unique features: 1) consists only few known constellation markers, 2) exploits break into many find global optimum solution, 3) reprojects 3D model reference final refinement. A comparison study provided demonstrate advantages solution over random basin hopping, general purpose optimization technique. After performing process shot, results show geometric error satisfactorily low successful reconstruction.
