Role of CTDI to estimate patient dose from a single slice to multi slice CT scanners


Mudassir Umar Ali

The purpose of this study was to provide additional information on the Role of CTDI in Estimating the Patient Dose in CT scanners. The CTDI (CTDIvol) which is the radiation output of a CT scanner for a single slice or multi slice CT scanners is derived from the 32cm or 16cm diameter body and head phantom respectively, CTDI is not an Estimate of a patient dose in each scanner since the patient characteristics are not taking into account it gives the quantitative dose estimation analysis and diagnostic reference level for the radiation for national and international level. A conversion factor can be developing so that CT scanner output can be translated into estimate of a patient dose. The Estimate of a patient dose must use patient size specifics. So CTDI alone cannot Estimate patient dose in a multi slice or single slice CT scanners only that multi slice CT scanner deliver higher radiation dose than single slice CT scanner, CTDI is measure in every period of time for quality assurance to know how the CT scanner is operated.
