The Analysis of Imaging Parameters of CR / 实用放射学杂志

ABSTRACT

Objective To measure the imaging parameters including the values of r(r),latitude(L),sensitivity(S)etc of imaging plate of CR by experiments.Methods The double-exposed method of lead steps was utilized to determine the imaging parameters of imaging plates. Results All the parameters of new IPs were suitable to practice and in the right range of clinical radiographic applications. The sensitivity(S) , however, was not at its optimal point at the beginning of the utilization, it would take certain time.Conclusion It would improve the medical image quality to use the changing parameters of CR correctly.
