WOBBLE COMPENSATION FOR COMPUTED TOMOGRAPHY APPLICATIONS

Systems, methods, and devices for determining relative and absolute positions and orientations of a detector and an inspection part of a CT system. In some cases positions/orientations of the detectorand the inspection part can be defined, at least in part, by tilt angles relative to reference axes and/or planes defined by various combinations of the reference axes. In some embodiments, sensors coupled to the detector and to a stage assembly having the inspection part coupled thereto can be used to determine the tilt angles of the inspection part and the detector, respectively. Data from thesensors characterizing tilt angles of the detector and the inspection part can be used to adjust projectional radiographs of the inspection part to correct for the mechanical wobble of the stage. By using tilt data to adjust projectional radiographs, the quality of tomographic images and 3 -dimensional reconstructions of the inspection part can be improved. 本发明公开了用于确定CT系统的检测器和检查零件的相对和绝对位置及取向的系统、方法和设备。在一些情况下，该检测器和该检查零件的位置/取
