Pre-Release 0.3.0

Pre-Release 0.3.0

This update features Array API compatibility, a FRED interface, VHEE model, documentation, examples in jupytext style, some refactoring and bugfixes.
We further are removing python 3.9 support due to array api compatibility.

New Features

• Partly integrated Array API compatibility. Coming with GPU support for Cupy and Torch. Note: Python 3.9 support has been removed.
• FRED interface (Monte Carlo tool)
• VHEE planning with a Generic (unfocused) beam and a focused beam.
• dij.compute_result_ct_grid() now returns quantities per beam too.
• create_body_segmentation() method for the CST object
• Option to cancel solver at any iteration via keyboard input

Bug Fixes & Performance

• Increased memory efficiency in dose calc
• Fixed overlap priorities when similar levels exist
• Fixed np.floating deprecation
• Fixed pydantic>=2.11 compatibility
• Fixed issues with single bixel calculations in Raytracer
• Elevated minimum required version of numpydantic
• Tuning of initial Scipy parameters

Full Changelog: v0.2.8...v0.3.0

Patch Release 0.2.8

This patch release incorporates performance improvements, plan analysis in form of DVHs, and some data validation fixes.

It corresponds to the version used in the SynthRad2025 challenge, see also https://github.com/SynthRad2025

Patch Notes:

• DVHCollection and DVH for plan analysis
• Ray Tracer recovery in case of numerical issues
• CT validates given x/y/z vectors correctly
• Fix for validating VOIs with single voxels from matRad
• performance improvements for raytracer and dij filling
• maps to associate bixel/beamlet indices with beams / rays in stf

Full Changelog: v0.2.3...v0.2.8

Full Changelog: v0.2.2...v0.2.3

v0.2.2

First official pre-release of pyRadPlan

pyRadPlan is an open-source radiotherapy treatment planning toolkit designed for interoperability with matRad.

Main Features

• matRad compatible data structures with stable validation and serialization with pydantic
• native reimplementation of matRad's pencil beam dose calculation for photons, protons & ions
• generic machine data
• native optimization framework using scipy or IPOPT (via ipyopt)

Disclaimers & License

pyRadPlan is still a work in progress, thus we decided to not assign a major version number yet. Everything is still subject to change, so handle with care.
