2012-07-14 · CT specific CTDIvol: milligray (mGy) DoseLength product (mGycm) RADIATION DOSE AND RISK IN CT Radiation Dose in Computed Tomography OBJECTIVE general milli Sievert [mSv] (whole body) CT specific CTDIvol: milligray (mGy) DoseLength product (mGycm) Explain risk of radiation exposure and Radiation dose parameters:

CTDIvol reported by scanner (mGy) for the protocol entered in the phantom site scanning data form (Note that this field is optional. This data may be entered into the dose calculation form and the database will calculate the percent difference between the calculated CTDI vol and that reported by the scanner.

Adult Head Scan. Pediatric Body. CTDI Dose Distributions by Year. 2012. Count 320. CTDI100 (mGy) is a linear measure of dose distribution over a pencil ionization chamber and hence does not take into consideration the topographical variation of CT specific CTDIvol: milligray (mGy).
