Innova4100血管机下肢静脉跟踪造影中的图像拼接问题分析与处理

目的:针对Innova4100血管机在下肢静脉跟踪造影中出现的图像拼接问题进行探讨并提出解决方法。方法:全部病例均经足背浅静脉穿刺后在高压注射器一次性注射对比剂的同时,通过控制导管床的移动速度与被检部位血流速度同步来获得连续动态静脉造影图像。结果:95﹪的图像主观评价背景干净,对比度良好,血管边缘锐利,病变部位清晰。结论:AdvPaste图像血管拼接处连续性好,可拼接成完整的下肢静脉图像,有利于对患者被检侧下肢静脉整体情况的了解与把握。

Image Manipulation of Lower Limb Phlebography in Innova4100

Objective To investigate the image manipulation of the lower limb phlebography in Innova4100. Materials and Methods All the patients were injected contrast agent by high pressure syringe through the vein of the dorsum of foot. The phlebography images were obtained by controlling the movement speed of the bed and blood flow. Results 95 percent of the images were excellent with good contrast and clear background. The blood vessel and the pathological changes were clear. Conclusion Adv Paste is a good software which can connected images to form complete phlebograms for lower limbs.
