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.
