Real-Time Three-Dimensional Reconstruction of Intraoperative Liver Surface Based on Structured Light Technique | Biomedgrid

The incidence of liver tumor is increasing year by year, and liver tumor resection is a routine operation for liver lesions. Liver tumor resection is more difficult than general surgery, mainly reflected in the liver itself is easy to deform, vascular density, complex structure and other aspects [1]. If the three-dimensional information of the liver surface can be obtained in real time during the operation, it will be helpful for doctors to observe the cutting status of the liver surface in real time and avoid the possibility of being cut by mistake to a large extent. Clinical studies have shown that failure to accurately locate the focal point of the liver during surgery, to obtain real-time three-dimensional information on the liver surface and to plan the surgical path are the most important reasons for the failure of such surgery [2].
