摘要: Monitoring of skin entrance radiation exposure in lengthy interventional procedures has been recommended because the potential for injury. Fluoroscopy duration and dose-area product (DAP) are readily available real-time measurements. It would be interest to study correlation these parameters radiation. Twenty neurological performed through aortic arch were monitored. Two pieces GafChromic XR Type R film placed between patient examination table. An observer recorded fluoroscopy DAP each phase procedure. Each was scanned post-procedure RBG mode, then image analyzed peak dose (in air kerma). All values corrected according a calibration with an ion chamber. With respective phases procedure, effective Reference Man calculated. For twenty cases, means standard deviations 17.2+/-6.4 min x ray on-time, 256+/-65 Gy cm (-2) DAP, 94+/-34 cGy kerma, 19.2+/-5.0 mSv dose, respectively. The correlated duration, r(2)-values 0.48, 0.46, 0.09, or not sufficiently strong infer from either parameters. Therefore, should determined directly.
