为了减少神经介入手术期间患者和工作人员的辐射暴露，在19例患者中使用了感兴趣区（ROI）技术和荧光透视、路线图和数字减影血管造影。将由多层钆制成的ROI过滤器连接到准直器。在85%的视野范围内，患者皮肤暴露量减少了3.3-10.0倍，暴露量降低至皮肤效应阈值以下。
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.
