ABSTRACT
Objective:To investigate the safety and protection level of radiological treatment in the CT modules in the makeshift hosptials in Wuhan during the prevention and treatment of COVID-19 cases.Methods:The layout of the CT modules in makeshift hospitals, radiological protection facilities and personal protective equipment were investigated. Based on the national standards, the CT dose index was estimated and the radiological protection level at the CT modules were measured.Results:The layout of the CT modules in makeshift hospitals is reasonable, with well-equipped radiological protection facilities. Of 23 CT modules, 20 were up to standards with acceptability of 87.0%. The other three were unqualified each with 1 detection points having values in excess of the national standards. Which, after being modified immediately reached the national standards. In addition, CT dose index for 7 CT modules were estimated, with CTDI W within ±7.5%. Conclusions:The CT modules in Wuhan meet the requirements of radiological safety and protection during the prevention and treatment of COVID-19 cases.
