conehead 💥

A collapsed-cone convolution radiotherapy dose calculation algorithm written in Python/Cython.

This project is currently in early experimental development. Expect the code to change dramatically over the coming months.

Inspiration has been drawn from Cho et al (2012) and Yang et al (2002).

Early development milestones:

• Linac geometry ✔️
• Water phantom ✔️
• Point source ✔️
• Annular primary collimator source ✔️
• Exponential filter scatter source ✔️
• Voxel blocking (Jaws, MLC) ✔️
• Fluence calculation ✔️
• TERMA calculation ✔️
• Kernel calculated (EDKnrc) ✔️
• Kernel convolution ✔️
• Kernel tilting
• Horn tuning factor ✔️
• Square fields ✔️
• Parse DICOM RT plan files (3DCRT ✔️, IMRT/VMAT)
• Import CT images
• Support density overrides
• Option to optimise for out-of-field dosimetry
