Radiomics Method Separates Voxel Geometry From Interpolation Effects in CT/MRI

A new arXiv preprint addresses a known pitfall in radiomic texture analysis: features are typically calculated over voxel-index neighborhoods, which assumes uniform spatial spacing. In anisotropic scans, this assumption mixes true voxel geometry with signal changes introduced by interpolation. The authors propose a physically aware approach that avoids interpolation so the two effects can be disentangled.
