The measurement and use of these quantities is described in this chapter. The CTDI is often substituted as the patient dose, but in reality is only tConcerto 发表于 2025-3-24 01:53:05

In response to the heightened awareness of the importance of patient dose contributed by radiology procedures, there has been a general trend to optimise CT examinations to obtain the required diagnostic outcommilligram 发表于 2025-3-24 02:27:35
