Sparse Concept Channels in Frozen 3D CT Vision Encoders

Farhad Nooralahzadeh, Lea Bogensperger, Christian Bluethgen +1

Large vision-language models are becoming increasingly dominant in 3D medical image interpretation, but we rarely know <i>which</i> internal units encode clinical findings or <i>wh…

CheXanatomy: Anatomy-Aware Vision-Language Modeling for Chest Radiographs

Sergios Gatidis, Curtis Langlotz, Christian Bluethgen

Vision-language models (VLMs) pretrained on large-scale image-text pairs demonstrate strong image-level understanding, but are primarily optimized for global alignment and do not e…
