Estimation of Patients Effective Dose with respect to BMI using Monte Carlo Simulation method for CT Coronary Angiography Patients
Arnabjyoti Deva Sarma , Dr.Mrinal Kanti Singha, Jibon Sharma
The identification of coronary artery diseases has been greatly helped by computed tomography (CT) images of the coronary angiography. The patient is exposed to significantly more radiation during this radiological test than during previous similar ones. The purpose of this study was to evaluate the effective dosage for computed tomography (CT) coronary angiography and optimise the radiation dose. 380 patients with coronary artery abnormalities were referred to the Primus Diagnostic Centre and Health City Hospital in Guwahati, Assam, throughout the research period. Data on the technical aspects of CT procedures were collected in 2022. Our study's aim was to estimate the organ and surface dose to a single radiosensitive organ (the chest) using the programme imPACT 1.0.4 and the SR250 Monte Carlo dataset from the National Radiological Protection Board (NRPB). The study's 380 subjects, who ranged in age from 29 to 75, comprised 190 men and 190 women. BMI and ED had corresponding Mean SD values of 22.42±1.06 and 21.57±4.27. The mean ED is 21.57 and the mean DLP is 854.67. Males (13-27) and females (13-29) received the same effective dosages of mSv. Because other nations have previously started with more advanced CT procedures including dosages for paediatrics, coronary angiography, and CT fluoroscopy, this study is truly a pioneer in presenting fundamental data of doses of CT examinations in Assam. With this study, there may be more opportunities to create complex new studies or enhance the data from related studies that may be done in future work. To achieve high precision with minimum risk, the current study can be considered as need of the our
