This collection includes data from 211 patients who presented with head and neck cancer and were treated using radiation therapy at a single institution using 6 MV Intensity Modulated Radiation Therapy (IMRT) from a linear accelerator. All patients were prescribed identical prescriptions of 70 Gray (Gy) in 33 fractions for the primary planning target volume (PTV) and one, none, or a combination of integrated boost sub targets (PTV 54 Gy, PTV 56 Gy, PTV 57 Gy, PTV 60 Gy, PTV 63 Gy, PTV 66 Gy). The data for each patient contains the minimum required information for radiation treatment planning. Each patient set contains the planning computed tomography (CT) image set from treatment simulation, the expert-defined radiotherapy structure set (RTSTRUCT), the delivered radiotherapy plan file (RTPLAN), and the calculated treatment dose (RTDOSE). All files are provided in DICOM format.

CT Images: Planning CT images from treatment simulation and radiation dose calculation are included for each patient. Thermoplastic head and neck masks were used during image acquisition to achieve immobilization and ensure accurate and reproducible positioning during treatment. All images satisfied the resolution requirements for dose calculations and have an identical slice thicknesses of 2.5 mm. The provided CT files are those that match with the RTDOSE and RTSTRUCT files of the same patient.

Target and Organ Contours: Each patient’s data contains an RTSTRUCT DICOM with manually defined target volume contours and organ at risk (OAR) contours. For efficient OAR extraction from the RTSTRUCT files, we renamed all OAR contours that could be identified to a uniform structure name. If a contour was not identified, it was not defined for treatment, or the nomenclature was ambiguous. All planning target volumes (PTV) are included in the structure set. Due to inconsistent documentation and naming conventions, the primary PTV is difficult to distinguish from other PTV structures. For example, some patients include multiple iterations of the same contour as a result of modifications during treatment planning our assisted planning methods from the TPS. In addition to organ and target structures, we chose to leave in planning structures created and used by the dosimetrists for generating the plan. For example, PTV expansions, ring structures, avoidance structures, and normal tissue volumes were left within the RTSTRUCT file. OAR contours for 26 unique normal tissue structures were renamed to the ‘Standardized Name’ in the RTSTRUCT DICOM file. If a structure was not identified, the structure was not created in the original structure set.

Radiotherapy Dose and Treatment Plan: Each dose was planned by a dosimetrist and approved for treatment by the physician. Treatment plans were created using Pinnacle (Phillips Medical Systems, Fitchburg, WI). The dose was calculated on a 3 mm3 dose grid and plans were optimized for treatment on Elekta or Varian linear accelerators.

Research for challenging tumor sites like head and neck cancers can benefit from publicly accessible radiotherapy treatment datasets such as the one offered here. In particular, this dataset provides consistent treatment plans with limited variance due to the uniformity in tumor site, consistent institutional standards, and identical prescriptions. In artificial intelligence research, the need for large and uniform datasets is crucial for testing and evaluating the performance of novel architectures. Treatments of a single site from a single institution and with identical prescriptions will have reduced variance of tumor coverage and normal tissue-sparing objectives in comparison to multi-site and multi-institutional studies. However, it can also be combined with other radiotherapy treatment datasets for use in more generalized studies.

By Technology Insights

The radiation based systems segment is estimated to witness significant growth during the forecast period. Image-guided radiation therapy (IGRT) is a non-invasive cancer treatment technique that utilizes medical imaging to deliver precise radiation dosages to tumors. Hospitals are increasingly adopting IGRT to minimize surgical complications and adverse effects during the post-treatment phase. IGRT ensures accurate tumor localization and reduces the risk of radiation exposure to healthy cells. This technology is gaining popularity in cancer treatment due to its ability to provide real-time imaging during the radiation therapy process. Despite its benefits, continuous radiation exposure can lead to various complications, such as skin irritation, fatigue, and long-term health risks. To mitigate these risks, medical organizations, including the Centers for Disease Control and Prevention (CDC) and the US Preventive Services Task Force (USPSTF), recommend low-dose CT scans for lung cancer detection.

Further, the increasing prevalence of cancer and the rising demand for non-invasive cancer treatment options are the primary factors driving this growth. In conclusion, image-guided radiation therapy is a vital advancement in cancer treatment that offers numerous benefits. However, it is crucial to ensure that patients receive proper care and follow-up to minimize potential complications. With the increasing prevalence of cancer and the rising demand for non-invasive cancer treatment options, the image-guided radiation therapy market is expected to grow significantly in the coming years.
