B-MIM: Biased Masked Image Modeling for Generalizable Segmentation of Fine-Grained Anatomical Structures
Sebastián González, Karen Sanchez, José M. Saavedra +2
Self-supervised pretraining enables transferable representations for medical imaging, yet most CT encoders remain biased toward coarse semantic understanding, limiting their sensit…

AST-n: A Fast Sampling Approach for Low-Dose CT Reconstruction using Diffusion Models
Tomás de la Sotta, José M. Saavedra, Héctor HenrÃquez +2
Low-dose CT (LDCT) protocols reduce radiation exposure but increase image noise, compromising diagnostic confidence. Diffusion-based generative models have shown promise for LDCT d…
