Building of 3D Image Based Operation Navigation Platform

摘要：

Radioactive particle implantation, as a means of interventional therapy in the treatment of malignant tumors, has achieved good results and rapid development in recent years. This technique uses computers to process CT images and provide doctors with real-time navigation. We aim to design and build a 3D image based operation navigation platform to assist the implementation of interventional operations. Features of our operation navigation platform include organ segmentation, operation planning and operation navigation. We used the improved graph cuts algorithm to ensure the speed and accuracy of segmentation; we designed an algorithm to find the range of target, and automatically compute the ideal positions of radioactive particles; we connected our operation platform with a navigation equipment to implement the real-time navigation of the position and orientation of the probe. Results on real CT images of patients demonstrate the effectiveness of the platform.
