검출기 중심축을 자동 보정하는 초소형 CT 개발 및 성능평가 = Development and Performance Evaluation of an Ultra-Compact CT with Auto Calibration of DetectorCenter Axis

다국어 초록 (Multilingual Abstract)

In this study, we designed and fabricated an ultra-compact CT that automatically calibrates the detector's center axis and verified its performance. The three-dimensional reconstruction performance was evaluated using 3D CAD data and X-ray data acquired by manually calibrating the center axis of the CT detector. The results showed that tilting the center axis by more than 0.25° causes circle break phenomenon, which rapidly degrades the quality of the 3D reconstructed image. By applying the automatic calibration device of a detector center axis, the 3D reconstruction performance was enhanced by calibrating the detector center axis to match the specimen rotation axis.
