Objective: To explore a CTCR quantification positioning method and its formula. MATERIALS AND METHODS: CR images were digitally and digitally reconstructed in chest, lumbar, and hip joints using a wide range of CT scanners and scan fields. Quantitative digit methods and their formulas were used to quantify and locate CR images, totaling 2 91 cases. Results: According to the quality standards of each CR department, the CR images of 2 91 different regions were evaluated and statistically analyzed. The results showed that the grade CR of the thoracic, lumbar and hip joints were 95%, 99%, 98% respectively %, The success rate of its CR scan reached 10%. Conclusion: CTCR quantification method and its formula, it is suitable for a variety of CT models at home and abroad, a variety of scanning fields and a number of inspection sites, can significantly improve the CTCR image scanning quality, CTCR image scanning with a scientific Quality control methods
