Abstract
The application discloses an image needle path extraction algorithm, comprising the following steps: scanning an image containing a needle path, and performing threshold segmentation on the image; performing connected domain analysis to obtain a plurality of connected domains, and screening a target region to be extracted; performing straight line fitting on a voxel point in the target region to obtain a straight line, and extracting an end point of the straight line to complete needle path extraction. The application performs robust regression analysis on a needle path coordinate point set, eliminates errors caused by metal artifacts in the image, and has high precision and high reliability in needle path extraction, and can be applied to most scenes.
