Background
Recently, the percutaneous coronary interventions(PCI) have increased the average procedural radiation dose. In themeantime, the number of radiation skin damage has increased. Thus,monitoring radiation dose is necessary. In clinical settings, dose-areaproduct (DAP) and air kerma (AK) are used to estimate patient peakskin dose (PSD). However, these data are calculated by using presumptive mathematic equations, which ignore each individual’scharacters and different projectors angles. Our study aims to providean easy method to record and estimate PSD with different tubeangulation in PCI settings.
Methods
Thermoluminescent dosimeters (TLDs) were used tomeasure radiation dose of Hp (10) and Hp (0.07) of skin. We used cinemode with a setting of 15 frames per second rate, recorded for 5 seconds and repeated for 5 times. We tested with standard tube angulations, such as posteroanterior view (PA), caudal 35-degree view(CAU 35), cranial 35-degree view (CRA 35), LAO 65-degree þ caudal 20-degree view (spider view), and left anterior oblique 50-degree view(LAO 50).
Results
The results showed the caudal 35-degree view had thehighest radiation dose in DAP, Hp (10) and Hp (0.07). When the zoomin stage was used, DAP reduced however AK and peak skin doseincreased.
Conclusion
Finally, we used values of skin dose of Hp (10) and Hp(0.07) compared to values of DAP in five groups, the value of PSD isabout between 3% to 7% of DAP. By sharing these experiences, weprovide an easy practicable method to estimate the PSD in the PCI foreach catheterization lab.
