AI Technical Summary

Technical Problem

Existing technologies for generating the contours of target structures from 3D scanned images suffer from problems such as high workload, long processing time, and insufficient accuracy. In particular, deep learning-based methods require a large amount of labeled data and fail to effectively utilize the anatomical information of organs.

Method used

By utilizing initial contour drawing, second-plane direction contour drawing, first-plane direction contour generation, and three-dimensional contour generation steps in a three-dimensional scanned image, combined with the LiveWire algorithm, the three-dimensional contour of the target structure is efficiently generated based on the anatomical information of the organ.

Benefits of technology

It achieves high-precision 3D contour generation, reducing user workload and time consumption, and can automatically and accurately draw the 3D contour of the target structure.
