To reduce radiation exposure to patients and staff during neurointerventional procedures, region-of-interest (ROI) techniques were used with fluoroscopy, road mapping, and digital subtraction angiography in 19 patients. ROI filters, made of multiple layers of gadolinium, were attached to the collimators. Patient skin exposure was reduced by a factor of 3.3-10.0 across 85% of the field of view, and exposures were reduced to below thresholds for skin effects.
为减少神经介入手术期间患者和工作人员的辐射暴露，对19例患者在荧光透视、路径图绘制和数字减影血管造影中使用了感兴趣区域（ROI）技术。由多层钆制成的ROI滤光片附着在准直器上。在85%的视野范围内，患者皮肤暴露减少了3.3至10.0倍，且暴露量降低至皮肤效应阈值以下。
