2 Aim 1 To ensure uniformity and high quality of test performance, image acquisition and image interpretation throughout the trialAim 1: To ensure uniformity and high quality of test performance, image acquisition and image interpretation throughout the trial Aim 2: To develop/deploy technical systems for test transmission and archiving, including creation of a unique data resource for ancillary studies by combining diagnostic tests and clinical dataAim 2: To develop/deploy technical systems for test transmission and archiving, including creation of a unique data resource for ancillary studies by combining diagnostic tests and clinical data 2

3 3 TRIAD Installation & TRIAD Installation & Sample Data Transfer

4 TRIAD TRIAD is the American College of Radiology Imaging Network’s (ACRIN) image acquisition and management software. In brief, TRIAD-OA offers a web-based software solution which allows sites participating in the RESCUE trial a secure method to review and submit clinical trial images. For a more detailed explanation of the capabilities and benefits of TRIAD, you may visit the TRIAD learning center at: https://triad.acr.org/ https://triad.acr.org/

5 TRIAD REGISTRATION and DEPLOYMENT

6 TRIAD DEPLOYMENT Identify the following key individuals at your site: TRIAD user – the individual(s) who will use TRIAD regularly IT contact – the individual(s) who will assist with the basic installation and testing of the TRIAD software PACS administrator (if necessary) – the individual(s) who will assist with transporting case images from the scanner/PACS system to TRIAD Register for a TRIAD account – this may be done by clicking on the following link: https://triad.acr.org/Web/UserAccount/Register.aspxhttps://triad.acr.org/Web/UserAccount/Register.aspx Determine the computer(s) which you would like TRIAD installed on (this machine does not need to be used solely for TRIAD) Determine a time and date that would work best to schedule the TRIAD installation
