NRG-RTOG Legacy Studies


The ACR/RTOG is taking steps to upgrade security when gaining access to patient registration and data systems.

The first time that you attempt to register a patient or enter data after the implementation you will be prompted to create an “Okta – ACR” username and password. Once you complete the section for your email and password, an email will be sent from “Okta” that will say “Activate Account”. To complete the set-up process, you must follow the link in the “Activate Account” email. Once you create the Okta account, that will be the account username and password you will use moving forward.

Please follow all the prompts and reach out to RTOG-UserAccounts at rtog-useraccounts@acr.org for questions.
