Advances in video technology have enabled the incorporation of high-resolution electronic imaging of an operative field during microneurosurgical and endoscopic procedures. While current video-based monoscopic camera and monitor systems produce an excellent image, the third dimension is lacking and the operative field and image are at different locations. We describe a head-mounted display (HMD) that allows the surgical team to simultaneously visualize a surgical field and a high-resolution magnified stereoscopic image which includes a picture-in-picture capability. Stereoscopic HMDs should result in improved efficiency and safety in both endoscopic and open microsurgical procedures. Additional uses relate to surgical training and operative rehearsals.
视频技术的进步使得在显微神经外科手术和内窥镜手术过程中能够对手术视野进行高分辨率电子成像。虽然当前基于视频的单目摄像头和显示器系统能产生出色的图像，但缺少第三维度，且手术视野和图像处于不同位置。我们描述了一种头戴式显示器（HMD），它能让手术团队同时可视化手术视野和高分辨率放大立体图像，还具备画中画功能。立体头戴式显示器应能提高内窥镜手术和开放式显微手术的效率及安全性。其额外用途还涉及手术培训和手术预演。
