title: Accuracy of a dose map method assessed in clinical and anthropomorphic phantom situations using Gafchromic films.
abstract: A dose map method has been integrated on GE x-ray angiographic systems to provide an indication of the local dose distributed on a patient envelope representative of individual patient shapes. Tests have been performed to assess the accuracy of the method by using Gafchromic XR-RV3 films in an anthropomorphic phantom situation and in a clinical situation. Dose values inside different exposed areas have been compared between the film and the dose map method. The dose map results show a good visual agreement for the anthropomorphic phantom situation, and the local doses agreed within better than 15 % compared with the Gafchromic films in both situations.
