摘要: The objective of this study was to assess and compare the organ effective doses in knee area resulting from different commercially available multislice computed tomography devices (MSCT), one cone beam device (CBCT) conventional X-ray radiography using MOSFET dosemeters an anthropomorphic RANDO phantom. Measurements MSCT resulted ranging between 27 48 µSv. CBCT measurements dose 12.6 attained were 1.8 µSv for lateral 1.2 anterior-posterior projections. considerably lower than those recorded devices. results two four times higher measured on device. This demonstrates that can be regarded as a potential low-dose 3D imaging technique examinations.
