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 the RTOG. See here for information on installing TRIAD.

In order to complete the IMRT credentialing process the following items must be completed:

• Complete/update the Facility Questionnaires.

•  Successfully complete the IGRT credentialing study if reduced margins are being used. Details can be found here. (Click here for IGRT data spreadsheet). Note: IGRT credentialing is not required for margins ≥ 5mm.

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

Note:

• Institutions that are credentialed to participate in other RTOG IMRT protocols requiring an IMRT H&N phantom irradiation might not need to repeat the phantom irradiation for credentialing for this protocol. To determine whether your institution needs to complete any further credentialing requirements, please complete the Credentialing Status Inquiry.
