Radiation therapy simulation head and neck CT and simulation MRI anonymized scans with region-of-interest contour sets

This is a collection of CT, MRI, and structure contour DICOM datasets acquired from 15 head-and-neck cancer patients under radiation therapy immobilization protocols. CT and MRI structure sets were contoured by four radiation oncologists at the University of Texas MD Anderson Cancer Center. Deformed structure sets are also made available. Deformed structure sets are the results after applying one of three deformable registration algorithms (using Admire, Pinnacle, or Velocity softwares) to MRI, holding the CT as primary.
