Electron spatially fractionated radiation therapy using a clinically biocompatible 3D‐printed tungsten‐filament GRID

Key Points

• The aim is to evaluate the feasibility of using a 3D-printed tungsten-filament GRID for electron spatially fractionated radiation therapy (eSFRT).
• Developed a tungsten-filament GRID collimator using 3D printing technology.
• Assessed its geometry, stability, and biocompatibility compared to traditional GRID materials.
• Conducted preliminary investigations into its dosing capabilities.
• The 3D-printed GRID collimator provided consistent and reproducible geometry.
• Demonstrated mechanical stability suitable for clinical use.
• Achieved spatially heterogeneous radiation doses effectively.
