单反相机辅助判读口腔科X线片的可行性研究

Reasearch about the feasibility of interpreting X-ray with the help of DSLR

目的:评价使用单镜头反光数码相机将传统X线片转化为数字图片并进行增强处理后是否能提高其可判读性。方法:使用三种不同测量方法,以相同的参照点测量同一组种植体周的骨高度,对三组测量结果分别进行配对t检验,评价不同测量方法所得数据的差异。结果:单反相机翻拍组与CT测量组的结果无统计学差异,而传统直接测量法所得结果与其他两组存在统计学差异。结论:传统直接测量法测量成像不佳的X线片时结果可靠性不高,将其用数码相机翻拍,进行数字增强处理后可在一定程度上提高其可判读性,有利于医生作出正确的诊断。

Objective：The purpose of this article is to evaluate the reliability of digital images enhanced by computer after converting from radiographic images by DSLR.Method：Measure the length of jaw bone around implants at the same starting point by 3 different methods.The results of this three methods were compared by paired t-test in order to know the discrepancy of them.Result：No significant difference was found between converting method and CT method（P 0.05）.Significant difference was found between direct measurement method and two other methods（P 0.05）.Conclusion：The accuracy of direct measurement method is not good enough.Converting radiographic images to digital images by DSLR and being enhanced by computer can raise the accuracy of measurement.So it is a good choice for doctor to make an accurate diagnosis with the help of DSLR.
