New PC-Seg framework uses sparse 2D annotations for accurate 3D OCT image segmentation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed PC-Seg, a novel framework for 3D segmentation of optical coherence tomography (OCT) images. This method utilizes semi-supervised learning to significantly reduce the need for extensive manual annotations, a common bottleneck in medical imaging. PC-Seg leverages cross-view consistency from sparse 2D annotations to generate reliable pseudo-labels, which are then used to train a 3D segmentation model. Experiments show that PC-Seg achieves accuracy comparable to fully supervised methods while requiring labels for only a small fraction of the data. AI

IMPACT This method could significantly reduce the cost and time associated with medical image annotation, potentially accelerating diagnosis and research in ophthalmology.

    PC-Seg: Progressive Cross-View Consistency for 3D OCT Segmentation from Sparse 2D Annotations

    arXiv:2607.17718v1 Announce Type: new Abstract: Volumetric segmentation of optical coherence tomography (OCT) images is essential for diagnosing ocular diseases but requires labor-intensive voxel-wise annotations. While semi-supervised learning (SSL) can reduce annotation costs, …
