Voxel Level Annotation

Voxel-level annotation in 3D medical imaging involves precisely labeling each individual voxel (3D pixel) within an image, a crucial step for training accurate deep learning models for tasks like organ segmentation and tumor detection. Current research focuses on mitigating the substantial cost and effort of manual annotation through techniques like semi-supervised learning, leveraging large language models to incorporate prior knowledge, and utilizing synthetic data or simplified annotation schemes (e.g., scribbles or skeletons). These advancements are vital for improving the accuracy and generalizability of AI-driven diagnostic tools in healthcare, ultimately leading to more efficient and effective medical image analysis.
