Minimum System Requirements

We develop matRad using mainly Windows and Mac systems and Matlab version 2014b and later. If you run into a problem with these or any other version, please do let us know!

To run all dose calculation und optimization functionalities you will only need a nacked Matlab installation. For DICOM import, though, you also need the Image Processing Toolbox.

There are no hard minimum requirements to do dose calculation and optimization with matRad. We do treatment planning tutorials also with systems with 2GB RAM but that means that the cases you are looking at are somewhat small (low spatial resolution, few beams, rather no particles). If you want to do treatment planning at realistic resolutions, we recommend 8GB RAM or more.

If you run into memory problems you have basically three options:

• Buy more RAM ;)
• Import your data at low spatial resolution, which is possible during DICOM import. Remember that reducing the resolution by a factor of 2 will reduce memory consumption by a factor of 8!
• Restrict the dose calculation area by specifying tighter lateral cut-off values in matRad_calcParticleDose (line 211) and matRad_calcPhotonDose (line 101), respectively. While this induces inaccuracy in the planning process this might be a viable option for educational purposes.
