A study on real-time shape measurement of abdominal organs under the minimum invasive surgery

由于外科医生的视野有限，在腹腔镜手术中必须使用特殊的器械，因此对外科医生的技术要求很高。为了解决这个问题，我们提出了一种计算机辅助手术系统，该系统将腹腔镜图像直接投射到患者的体表上，以辅助和增强外科医生的视野。然而，该系统无法实时获取和投影三维变化信息。因此，在本项目中，我们开发了一种新的专门用于获取腹腔内大量信息的成像装置，并提出了不同图像模态之间的融合算法。最后对手术辅助系统进行了整体评价。

Since surgeons have quite limited view and are obliged to use special instruments in the laparoscopic surgery, it requires high skills for surgeons. To address this problem, we have proposed a computer-aided surgery system which projects the laparoscopic image directly onto the patient's body surface to assist and enhance the surgeon's view. However, the system could not obtain and project the 3D information changing in real-time. Therefore, in this project, we developed a new imaging device specialized for obtaining plenty information inside the abdominal cavity, and proposed a fusion algorithm between different image modalities. Finally we performed the overall evaluation of the surgery assistance system.
