We describe a distortion correction algorithm for OCT images based on the scalpel. In this algorithm, the distorted OCT images are segmented into three parts depending on the seven customized fiducials. Image translation and image stitching are used to eliminate the majority of the distortions. After performing experiments with porcine eyes, we basically correct the optical distortions caused by the reflection and interlayer scattering effects. The correction error is less than 2%. Our algorithm could bring many potential applications in ophthalmic procedures.
