A model of the approximate calculation for total radiation dose during fluoroscopy and the relationships among the influencing factors. Total Dose = 1Dose Rate × 2Fluoroscopy Time; 1Dose Rate = 3Dose/Frame × 4Frame Rate. Here, total dose indicates the air kerma, entrance skin dose or radiation dose. Dose-area product/kerma-area product is not applied. Technically, the total dose must be added from standard radiography and cineradiography.
