Quality assurance software: (i) Isocenter/Collimator check for linear accelerator (Winston Lutz Test), (ii) Iridium-192 3d dose calculation, (iii) Gamma3D-criterion calculation, (iv) Hexapod 6-axis check via Penta-Guide Phantom, (v) ...

During the past few years, I created a range of user-friendly software tools designed for clinical use. These tools, written in Python, automate various processes to simplify tasks in clinical routine (reading, modifying and analysing DICOM data, sphere and MLC detection, 3D dose calculation, 3D dose comparison, automatic treatment plan generation, time-series plotting, PDF-Report generation, ROI analysis and VMAT treatment plan complexity analysis). They're freely accessible for anyone interested, so feel free to ask for the source code if needed. I'm always open to feedback and suggestions! Hannes Rennau
