Purpose:
To evaluate the efficacy of low-dose fluoroscopicexamination for reduce radiation dose in the bi-plane angiography equipment.
Materials and Methods:
We used glass dosimeter and RANDO phantom to measurethe radiation dose. The surface organ absorbed dose(SOAD) of the phantom was measured at the brain, thyroid, middle forehead, and left external auditory meatus, respectively. The air scattered dose(ASD) was measured four points at 75 ㎝-distance and two points at 150 ㎝-distance from the detector. We evaluated the reduced rate of SOAD and ASD when normal fluoroscopy versus low-dose fluoroscopy and the reduced rate of SOAD when single fluoroscopy versus RoadMaP condition.
Results:
The reduced rate of SOAD under low-dose fluoroscopy was 43.1%, 43.6%, 54.2%, and 50.4% at the brain, thyroid, middle forehead, and left external auditory meatus, respectively. The reduced rate of ASD was 49.5% at 75 ㎝-distance and 44.6% at 150 ㎝-distance from the detector(p＜0.05). The increased rate of SOAD under RoadMaP condition was 28.3%, 8.8%, and 11.3% at the thyroid, middle forehead, and left external auditory meatus, respectively. The radiation dose at the brain reduced 28.5% (p＞0.05).
Conclusion:
The low-dose fluoroscopic examination seems to be useful technique for reduce radiation dose in the bi-plane angiography equipment.
