3D: coming soon, to an operating theatre near you
3D：3D时代即将来临，让手术室与你更贴近

Do Na’vi actually have gall bladders?
纳维人真的有胆么？
IN “AVATAR”, a film that has enjoyed a certain modest success at the box office recently, 3D technology brought blue-skinned extraterrestrials to life. On June 10th, a similar innovation helped improve life on Earth when Iain Jourdan, a surgeon at the Royal Surrey County Hospital, in Guildford, England, donned polarising glasses to perform the first-ever laparoscopic surgery assisted by three-dimensional imaging.
最近电影《阿凡达》享有了眼下火爆的票房。片中，3D技术把蓝肤外星人带进了我们的生活。6月10日，一个类似的创新帮助我们地球人改善了生命。英国吉尔福德皇家萨里郡医院的外科医生伊恩?朱丹戴上偏光镜，在三位成像的辅助下做了有史以来{dy}例腹腔镜手术。
The procedure he performed, a routine gall-bladder removal, is typically done by incising a slit in the patient’s navel, through which a tiny camera is inserted. Guided by the resulting video feed, the surgeon wields long-handled tools to excavate the gall bladder from its neighbouring organs before removing it though the slit. Until now, however, that video has been in two dimensions. Anyone who has tried threading a needle with one eye shut will understand that this is not ideal.
他做的是常规胆囊切除术，典型做法是在病人的肚脐上开个小口，通过这个小口插入一架微型摄像机。在摄像机所拍视频图像的指导下，尽管口很小，外科医生还是操纵长柄工具将胆囊从其邻近器官上挖出来，之后切除它。不过截至目前手术用的视频一直都是二维成像的。任何尝试过闭着一只眼纫针的人都会知道这个二维的不理想。
Past attempts to design a 3D display for use in the operating theatre have not worked. One prototype, a stereoscopic helmet worn by the surgeon, left users seasick after only a few minutes. The new system, manufactured by Solid-Look, a firm based in New York, abandons such missteps in favour of technology originally developed for the entertainment industry: 3D glasses and a specially modified television screen.
过去尝试设计的手术室专用3D显示器一直没有成功。有一个外科医生戴的立体头盔原型让使用者戴了几分钟后就头晕。在原本为娱乐业开发的技术的支持下，总部设在纽约Solid-Look公司制造的新系统避免了这种失策，3D眼镜和特别改装的电视屏幕问世了。
During the surgery, a camera sends back two live video feeds taken from slightly different angles, as it surveys the abdominal cavity from within. The signals are polarised in opposite directions, and the resulting images displayed as alternating rows of pixels on a high-definition television screen. The polarising lenses of the glasses filter these images, meaning each eye sees only one of them. The brain then adds them together as if they were natural, to create the impression of depth, as well as width and height.
外科手术时，当摄像机从内部环视腹腔时，送回两个从略有不同的角度拍摄的视频图像。将两个视频图像信号反向偏光，所得视频图像在高清晰度电视屏幕上隔行交替显示。偏光眼镜的偏光镜片过滤这些视频图像，意即每只眼睛只能看到两个视频图像其中之一。然后大脑把这两个视频图像就象自然状态那样叠加在一起，从而产生具有深度以及宽度和高度的景象。
The resulting vista of receding cavities and organic bulges allows for more accurate cutting and stitching. The first gall bladder removed by Mr Jourdan using the new system was extracted in 30 minutes, less than the normal average.
所拍的后退腔和器官膨胀景象使得切割与缝合更加xx。朱丹用新系统切除的{dy}例胆囊在30分钟内被取出，少于正常的平均时间。
3D thus looks as though it could be poised for a dramatic future. And with the laparoscopic-device market valued at more than $5 billion a year, the new technology could soon be a medical, as well as cinematic, blockbuster.
如此看来3D似乎会迎来一个引人注目的未来。凭着腹腔镜设备的市场销售额每年超过50亿美元，这项新技术可能不久就会在医疗界以及电影界大放异彩。
