摘要

目的：

探讨DR全自动拼接技术在青少年脊柱和双下肢全长摄片中的应用优势。

方法：

随机抽取2015年7月2017年2月期间患儿的脊柱及双下肢全长手动拼接摄片和全自动拼接摄片图像各25例，分别从图像质量、接缝有无误差及相接图像对比度是否一致等方面进行比较。

结果：

全自动拼接技术摄片：图像质量较好，图像接缝无误差以及相接图像对比度一致，拼接甲等片率为100％(25/25)。手动拼接摄片：图像甲等片率为48％(12/25)，乙等片率为44%(11/25)，丙等片率为8%(2/25)。手动拼接摄片主要问题为拼接处存在一定误差及错位，曝光相邻区域对比度不一致，图像质量欠佳。

结论：

DR全自动拼接技术是数字化拼接技术的新纪元，它比传统手动拼接更准确，更清晰，可为治疗方案提供有价值的参考依据。

Abstract

Objective:

To investigate the advantage of DR automatic splicing technology in the radiography of adolescent whole spine and double lower limb length.

Methods:

The data of childrens spine and double lower limbs length during Jul. 2015 to Feb. 2017 were randomly chosen. There were 50 cases included by manual (25 cases) or automatic splicing technology (25 cases). The image quality

image joint error and image contrast were compared.

Results:

By automatic splicing technology had better image quality

no image joint error

and good image contrast. The first class rate of image was 100% (25/25). By manually splicing technology

the first class rate of image wass 48% (12/25)

the second class

rate of image was 44% (11/25)

the third class rate of image was 8% (2/25). It had worse image quality and worse image contrast exposured to neighboring area with image joint error and dislocation.

Conclusion:

DR automatic splicing technology is a new era of digital splicing technology. It is more accurate than traditional manual splicing technology

and can provide more valuable reference for treatment.
