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，这对外科医生的技能提出了很高的要求。为了解决这个问题，我们提出了一种计算机辅助手术系统，将腹腔镜图像直接投射到患者的身体表面，以帮助和增强外科医生的视野。然而，该系统不能实时获取和投影变化的三维信息。因此，在本项目中，我们开发了一种新的成像设备，专门用于获取腹部内部的大量信息，并提出了一种不同图像模式之间的融合算法。最后对手术辅助系统进行了总体评价。

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.
