MedPruner: Training-Free Hierarchical Token Pruning for Efficient 3D Medical Image Understanding in Vision-Language Models
arXiv:2603.11625v2 Announce Type: replace-cross Abstract: While specialized Medical Vision-Language Models (VLMs) have achieved remarkable success in interpreting 2D and 3D medical modalities, their deployment for 3D volumetric data remains constrained by significant computational inefficiencies. Current architectures typically suffer from massive anatomical redundancy due to the direct concatenation of consecutive 2D slices and lack the flexibility to handle heterogeneous information densities across different slices using fixed pruning ratios. To address these challenges, we propose MedPrune
The proliferation of Vision-Language Models in medical imaging is exacerbating computational bottlenecks, making efficiency improvements critical for their widespread adoption and practical utility.
Improving the efficiency of 3D medical image analysis for VLMs significantly lowers computational costs and increases the accessibility and deployment potential of advanced diagnostic AI, impacting healthcare delivery.
This advancement changes the paradigm by enabling more efficient processing and deployment of complex 3D medical AI, potentially freeing up compute resources and accelerating clinical integration.
