.. _cort: ================ The CORT Dataset ================ The matRad release includes five image datasets of phantoms and patients. Consequently, everybody can start treatment planning out of the box without the need for their own data. Besides a simple cubic box phantom, matRad also features the four datasets that have been published as the `CORT dataset `_. The `CORT dataset `_ (common optimization for radiation therapy) is an open dataset intended to be used by researchers when developing and contrasting radiation treatment planning optimization algorithms. It is comprised of datasets for a prostate case, a liver case, a head and neck case, and a standard IMRT phantom (TG119). In matRad, these datasets are already imported and ready to be loaded as MATLAB native ``.mat`` files. To allow rapid prototyping and reasonable performance in educational settings, the CT images were downsampled at import. If you wish to take a look at the original data, you can find it `here `_. The dataset contains the original Digital Imaging and Communications in Medicine (DICOM) computed tomography (CT) scan, as well as the DICOM structure file. In addition, the dose-influence matrix from a variety of beam/couch angle pairs is provided for each case. Besides the pre-configured patient datasets, matRad also features a :ref:`DICOM import `.
