【摘要】 目的　对数字影像会诊系统的创建、初步应用及其特点进行探讨。方法　双屏图文工作站 1台 ,MatroxG4 5 0AGP双头显卡 1块 ,多媒体投影仪 2台 ,投影大屏幕 1个 ,线对灰阶测试卡 1个。在Intranet和医学影像存储与传输系统 (PACS)的基础上 ,使用GERadworks软件对患者在放射学信息系统 (RIS)上的信息和PACS图像调阅 ;并对图像的调取速度、分辨率及灰阶度进行测试。结果　成功使用MatroxG4 5 0双头显示卡将图像和文字单独或同时在 2个屏幕上显示 ,并完成图文双屏和图像双屏的快速切换。图像调阅速度快、分辨率高 (12LP)和灰阶度良好 ,且图像无失真变形。结论　数字影像会诊系统具有调取速度快、分辨率高、功能完善、优良的效价比、操作简便、实用可靠等优势 ,值得推广。更多还原

【Abstract】 Objective To investigate the set up and preliminary practice of digital radiology conference system and its characteristics. Methods One set image word workstation with two screens, 1 Matrox G450 demonstration DualHead card, 2 multimedium projectors,1 large screen, and 1 measured card of line pair and grey scale were set up.The patient′s informations on RIS and images on PACS were fetched with GE Radworks software based on Intranet and PACS.The fetching velocity, resolution, and grey scale of the image were measured. Results Words and images of the patient were demonstrated successfully on two screens with Matrox G450 demonstration DualHead card and switched rapidly between word image two screen and image two screen, the fetching velocity of the image was fast, the resolution was high (12 LP), the grey scale was good and the image was ture to the original. Conclusion The digital conference radiology system is good, and worth to be popularized.更多还原
