ESTIMATION OF TOTAL EFFECTIVE DOSE AND ABSORBED DOSE FOR LUNG, BREAST AND LIVER IN CHEST HIGHRESOLUTION COMPUTED TOMOGRAPHY
(2022) Reem Jafar Abu-Sa’a
This study is aiming to see the doses that reach the patient from CT scan ionizing radiation. Due to the high concerns recently about the affection of CT doses in producing longterm radiation risks. An estimating for the effective doses of chest and absorbed doses for each of liver,lung and breast in HRCT chest scan were done. A sample within (39) for patients that were undergoing scanning at .Thebet-Thabet hospital in Tulkarm city, Palestine. it was used for both genders at ages ranged from (13-82), important parameters were used to investigate doses such as DLP, CTDIw and mAs to calculate the total effective and absorbed dose. Methods of three types were used to estimate these doses such as virtual, manual method. By using the previous methods and analyzing the data, there was an obvious increase in female doses and patients how were above (40) y.o, and for organ absorbed doses, the lung was the highest than liver and breast and the least was liver doses. With the maximum effective doses (36.01), (23.94) and minimum effective doeses (1.5), (1.16) for virtual and manual methods respectively, which will be discuss later
