Beyond 2D Evaluation: MRI Polymer Gel–Based 3D DVH Verification for VMAT Lattice Radiotherapy

Lattice radiotherapy (LRT) produces steep vertex–valley gradients, making 2D gamma-based QA insufficient for clinically relevant 3D dose–volume endpoints. We propose an MRI polymer gel–based 3D DVH verification workflow for VMAT-LRT and assess feasibility and...

Vertex-Wise 3D QA for Lattice Radiotherapy Using Segmented Isodose Structure Analysis

This study proposes a vertex-wise Isodose Structure (IS)-based framework to evaluate the 3D geometric accuracy of Lattice Radiotherapy (LRT) dose distributions by decoupling geometric misalignment from dose-dependent volumetric distortion, enabling vertex-spe...
