目的 :评价平板式全数字心血管造影机在周围血管及非血管介入中的应用价值。方法 :对平板探测器(FPDD)X线成像与影像增强器 电视 (IITV)X线成像在动态范围、成像均匀性、对比度线性、对比分辨率等图像质量指标的检测及比较。随机选择上述两机型在周围血管及非血管介入诊疗病例图像资料各 6 0例 ,由三名高年资医师对其图像质量进行综合评价 ,记录评价结果 ,并进行比较。结果 :FPDD成像在动态范围、成像均匀性、对比度线性、对比分辨率等图像质量指标均优于IITV成像 ;在人体各部位周围血管及非血管介入诊疗中的图像综合评价结果也优于IITV成像。结论 :平板式全数字化心血管造影机不仅适用于心血管介入 ,同时能满足全身各部位周围血管及非血管介入诊疗的需要。
Objective: To evaluate the value of plate digital all-in-one cardiovascular angiography in peripheral vascular and non-vascular intervention. Methods: The detection and comparison of image quality indexes of FPDD X-ray imaging and IITV X-ray imaging in dynamic range, imaging uniformity, contrast linearity, contrast resolution and so on. Randomly selected the above two models in the peripheral vascular and non-vascular interventional case of image data of 60 cases, three senior physicians on its comprehensive evaluation of image quality, record the evaluation results, and compared. Results: The image quality indexes of FPDD imaging were better than IITV imaging in dynamic range, imaging uniformity, contrast linearity, contrast resolution and so on. The comprehensive evaluation of images in the peripheral vascular and non-vascular interventional treatment of human body was also superior to IITV imaging . Conclusion: The plate type all-digital cardiovascular angiography is not only suitable for cardiovascular intervention, but also can meet the needs of vascular and non-vascular interventional treatment around the various parts of the body.
