Summary
This data set was provided in association with a challenge competition and related conference session conducted at the AAPM 2019 Annual Meeting. MRI is popular in radiation oncology because of its excellent imaging quality of soft tissue and tumor. With the advent of MR-Linac and MR-guided radiation therapy, there is a trend toward a MR-based radiation treatment planning. Contouring is an important task in modern radiation treatment planning and frequently introduces uncertainties in radiation therapy due to observer variabilities. Auto-segmentation has been demonstrated as an effective approach to reduce this uncertainty. The overall objective of this grand challenge is to provide a platform for comparison of various auto-segmentation algorithms when they are used to delineate organs at risk (OARs) or tumors from MR images for head and neck patients for radiation treatment planning. The results will provide an indication of the performances achieved by various auto-segmentation algorithms and can be used to guide the selection of these algorithms for clinic use if desirable. The data for this challenge contains a total of 55 MRI cases, each from a single examination from a distinct patient, with each case consisting of a T2-weighted MRI images in DICOM format. The MRI scanning protocol was designed for radiation treatment simulation. Thirty-one of these will be provided as training cases, with the parotid glands, submandibular glands, level 2 and level 3 lymph nodes contoured. The images and contours were acquired from MD Anderson Cancer Center. More details on accessing the various challenge subsets (training, off-site test, and live test) can be found on the Detailed Description tab below.

Detailed Description
Supporting Documentation and Metadata
Some information from the 2019 challenge site https://www.aapm.org/GrandChallenge/RT-MAC/ is included below.
Data description
T2 MR Images of 55 patients have been collected for this challenge. Data were acquired from MD Anderson Cancer Center. All images were scanned with a protocol specifically designed for head-and-neck radiation treatment simulation. Datasets were divided into three groups:
- 31 training datasets
- 12 off-site test datasets
- 12 live test datasets
Data will be provided in DICOM (both MR and RTSTRUCT), as commonly used in most commercial treatment planning systems.
Contouring Guidelines
The manual contours were drawn by a radiation oncologist at MD Anderson Cancer Center. The structures were contoured following the DAHANCA, EORTC, GORTEC, HKNPCSG, NCIC CTG, NCRI, NRG Oncology and RROG consensus guidelines reported in Brouwer et.al Radiotherapy and Oncol. 2015. Details of contouring guidelines can be found in “Learn the Details” on the challenge website. The following structures are included in this challenge:
- Parotid glands
- Submandibular glands
- Lymph nodes level II
- Lymph nodes level III
Training Data
Each training dataset includes a set of DICOM MR image files and one DICOM RTSTRUCT file. Each training dataset is labeled as RTMAC-TRAIN-xxx, where xxx identifies the dataset ID.
