Abstract
Disclosed is a method (100) for correcting artifacts in Optical Coherence Tomography (OCT) images. The method involves acquiring an OCT image and subsequently transforming it from a Cartesian coordinate system to a polar coordinate system via polar reconstruction, generating a reconstructed polar OCT image. This image is then segmented into RED, GREEN, BLUE color channels. Fourier transformation is applied to each channel, transitioning them into their frequency domain representations. A custom frequency mask is utilized on these images, filtering out artifact-related frequencies. Following this, an inverse Fourier transformation is executed, reverting the images back to their Cartesian format. These images are then combined to produce a reconstituted OCT image. Further, this reconstituted image is merged with the original OCT image, resulting in an OCT image that is substantially free from artifacts.
