Algorithms and interfaces for improved image-guided surgery

这个研究项目旨在回答这样一个问题：“我们如何改进图像引导手术（IGS）的计划和性能？”IGS为外科医生提供手术计划和术中干预指导的方法。一般来说，程序是一个三步的过程：i)医学图像采集，ii)规划和，iii)导航。在图像采集过程中，使用医学成像（如CT、MRI）扫描解剖结构。在计划阶段，从图像数据集中提取相关数据（例如骨、软骨），构建三维（3D）解剖模型，并计划手术干预。在手术过程中，跟踪系统，如光电相机，被安装在手术室，传感器被固定在解剖和手术器械上。摄像机从这些传感器读取信息，然后使用计算机图形和配准算法在解剖学和/或计划的仪器轨迹的虚拟表示上呈现仪器的跟踪位置。

This research program is directed to answering the question: "How can we improve the planning and performance of Image-Guided Surgery (IGS)?" IGS provides surgeons with methods for surgical planning and guidance for intra-operative interventions. In general, the procedure is a three step process: i) Medical Image Acquisition, ii) Planning and, iii) Navigation. During image acquisition, the anatomy is scanned using medical imaging (e.g. CT, MRI). In the planning phase relevant data (e.g. bone, cartilage) are extracted from the image dataset and a 3-dimensional (3D) model of the anatomy is constructed and surgical interventions are planned. During the surgery a tracking system, such as an opto-electronic camera, is installed in the operating theater and sensors are rigidly attached to anatomies and surgical instruments. The camera reads the information from these sensors and then computer graphics and registration algorithms are used to render the tracked position of the instruments on the virtual representation of the anatomy and/or the planned instrument trajectory.
