Institutions that were previously credentialed to participate in another protocol or have a question about your status for this protocol, please fill out the Credentialing Status Inquiry form.

This study requires credentialing. The credentialing requirements are different depending on whether you are using a 3DCRT or IMRT technique. You can be credentialed for either 3DCRT or IMRT or both depending on your physician’s preference.

In order to complete the 3D credentialing process, an institution must:

• Complete the 3D benchmark. Questions about the 3D benchmark can be directed to IROC Houston at 713-745-8989.

In order to complete the IMRT credentialing process, an institution must:

• Complete and submit the IMRT Facility Questionnaire.

• Irradiate the IROC Houston's IMRT H&N phantom.¹  Please fill in the phantom request form online.

OR

• Complete and submit the IMRT Benchmark to IROC Houston.

Note:

¹ Institutions that have previously successfully irradiated the H&N phantom may not need to repeat a phantom irradiation.
