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.

PyRadiomics extension adds voxel-spacing awareness for anisotropic texture analysis

Researchers implemented and validated a modification to the PyRadiomics library that accounts for voxel spacing when computing texture features from anisotropic CT and MRI scans. In such acquisitions, equal voxel offsets can correspond to different physical distances, which the extension aims to correct. The work targets more consistent radiomic feature extraction in clinical imaging pipelines.
