摘要
双能计算机断层成像(CT)技术具有同时对物质结构和成分进行重建的能力,已被广泛应用于医疗、工业等领域。本文将双能CT技术引入至文物保护中,选取两种小尺寸青铜器腐蚀病害(密闭中空物体内表面病害和实心物体内部病害)作为研究对象。研究结果表明,重建结果的相对误差在10%以内,初步验证该方法可为文物保护人员更进一步了解病害腐蚀情况、制定有效的文物修复方案提供依据。
The dual energy computed tomography(CT)technology has strong identification capabilities for both structure and composition,which has been widely used in medical,industrial and other fields.In this paper,the dual energy CT technology was put into the cultural protection field,and two small size bronze corrosion defects(the defects are respectively in a sealed hollow inner surface and inside a solid object)were selected.The results show that the reconstruction relative error is within 10%.The preliminary results can be used to understand corrosions better and develop more effective rehabilitation plan for cultural protection researchers.
