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 NRG. See here for information on installing TRIAD.

For this study, when credentialing for IMRT or protons, IGRT is required.

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

• All participants are asked to complete the Facility Questionnaires.

•  All participants must complete   IGRT credentialing  for bony alignment.   Please also complete the   IGRT questionnaire .

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

In order to complete the Proton (IMPT & PBS) credentialing process, the following items must be completed:

• All participants are asked to complete the Facility Questionnaires.

•  Successful completion of the IROC Houston proton approval requirements (baseline phantoms, electronic data transfer, annual output check, site visit, and proton questionnaire).

•  All participants must complete   IGRT credentialing  for bony alignment.   Please also complete the   IGRT questionnaire .

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

Note:

• Institutions that are credentialed to participate in other RTOG or NRG 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
