Please fill out the credentialing status inquiry form to let us know that you would like to be credentialed for this protocol.

This trial will utilize TRIAD for dosimetry digital treatment data submission. TRIAD is the American College of Radiology’s (ACR) image exchange application and it is used by NRG. See here for information on installing TRIAD.

For this study, no credentialing is required for 3D CRT.

For this study, all sites are required to be IMRT credentialed. In order to complete the IMRT credentialing process the following items must be completed:

• All participants are asked to complete the Facility Questionnaires.

• Irradiate the IROC Houston's H&N phantom. Please fill in the request form online.

• Each treating physician must download and complete the benchmark case and submit to TRIAD. Sites are to generate an IMRT plan for WBRT with hippocampal avoidance as per protocol criteria. (Note: 1).Both CT data sets (CT and MRI ) were included in the Benchmark, and can be uploaded into TPS at the same time.
2). Institutions will be credentialed for either IMRT or VMAT depending on how the benchmark plan was created. If an institution wants to be credentialed for IMRT and VMAT then two benchmark submissions are required; one IMRT and one VMAT)

Note:

• Institutions that are credentialed to participate in other RTOG IMRT protocols requiring an IMRT H&N phantom irradiation need not repeat the phantom irradiation for credentialing for this protocol.

• Treating physicians and sites credentialed for RTOG 0933 (phase II study of hippocampal avoidance during WBRT for brain metastases) or NRG-CC003 (phase IIR/III study of prophylactic cranial irradiation with or without hippocampal avoidance for small cell lung cancer) will not be required to pass Benchmark Testing for NRG-CC001.
