To be able to record, if exposure modulation has been used to reduce the dose applied to the patient, “Exposure Modulation Type (0018,9323)” shall also be included within the CT Dose SR report for information and evaluation.
For the CT specialist or for the physicist it shall be possible to get an overview about measures used for dose saving.
The Effective Dose Conversion Factor is the ratio of the Effective Dose to the DLP, expressed in units of mSv/mGycm, and it is used as a factor in one method of estimating Effective Dose. Monte Carlo Simulations (or dosimetric measurements in an anthropomorphic phantom, e.g., the Alderson-Rando phantom) may be used as a basis for the evaluation of Effective Dose Conversion Factors.
The type of exposure modulation. May use the value of Exposure Modulation Type (0018,9323) from CT Exposure Macro or from CT Image Module.
