In 1993 RIT established the gold standard for precision dose image QA, and in 1997 developed the first IMRT QA software, making IMRT treatment feasible not just in centers with large staffs and budgets, but also in local centers of any size.

Here are some other RIT "firsts, bests and onlys".

•  Only complete dose image QA to provide interfaces to every commercially available TPS, and at no additional cost
• Only QA product that uses Film, EPID, CR, Ion Chamber Arrays, and Bang Gel, with no additional hardware, software, or cost
• Only QA software to support all commercial EPIDs
• First and only software to offer Plan Based Calibration (US Patents 7024026 & 7233688)
• First to offer automated MLC tests
• First and only to offer MLC Calibration Technique (US Patents # 6675116, 6934653 and 7013228, International Patents Pending) that meets the recommendations in "Guidance document on delivery, treatment planning, and clinical implementation of IMRT: Report of the IMRT subcommittee of the AAPM radiation therapy committee"*
• First and only QA software to offer Statistical Process Control Analysis for therapy QA measurements
