BETTER ESTIMATING RADIATION EFFECTIVE DOSE FROM CARDIAC COMPUTED TOMOGRAPHY (CT): A COMPREHENSIVE EXAMINATION OF THE RELATIONSHIP BETWEEN EFFECTIVE DOSE AND DOSE-LENGTH PRODUCT

Radiation from CT is commonly quantified in term of effective dose (ED), estimated by multiplying the scanner reported dose-length product (DLP) by a conversion factor, referred to as the k factor. Current guidelines suggest a k factor of 0.014 mSv·mGy-1cm-1 for chest CT. While this value is
