CR在传统口腔曲面断层摄影中的探索和改进

Exploration of application of CR in conventional pantomography equipment

目的：介绍传统口腔全景机获得数字化影像的一种简便和实用的方法,并探讨其应用的临床价值。方法：利用现有的岛津曲面断层机设备,自制盛装IP板的特制软皮套载体,在摄影时用它把IP板的软和IP板盒的硬进行互相转化,摄影完后用西门子数字成像处理系统对已摄影好的IP板进行扫描,再用Sony相机打印,从而得到口腔全景数字化影像。结果：改进技术后得到了高质量的数字化影像,随机搜集200例影像资料,进行质量评比和统计分析,其优片率达97%以上。结论：此技术可获得与其它CR一样优点众多的口腔曲面全景数字化影像,可与医院设备支持匹配,合理优化资源,且具有动态范围调节灵活、投资小、收效大等优点。

Objective：To introduce a simple and practical method to obtain digital images produced by dental panoramic equipment,and to explore its clinical practice value.Methods：By using the exising Shimadzu pantomography equipment and the self-made soft-leather carrier containing IP plate,the softness of IP plate and the hardness of IP cassette were transformed mutually in photography.Digital images of high quality were obtained by adopting Siemens digital imaging processing system to scan the IP plate and Sony laser camera to print.Results：We got the digital images of high quality with the improved technology and collected 200 capies of films.Quality assessment and statistical analysis were carried out,with excellent films up to 97%.Conclusion：Digital panoramic images can be obtained with the same advanteges as those of CR used in the other fields.This technology can be matched with the support of the original equipment to achieve the optimization of rational use of resources.It has many advantages such as flexible adjustment,low investment,high effeciency and so on.It will have a promising future in the field of digitalization of modern medicine.
