RTI Group is a world-leading manufacturer of Quality Assurance (QA) solutions.

In 1982 we launched the DIGI-X, the first X-ray QA system for diagnostic radiology. Since then, innovation has been at the heart of our corporate philosophy, and we have pioneered many QA procedures. We continue to invest heavily in R&D to push forward the very edge of X-ray QA, across all modalities.

Longer and more active lives, combined with a string of new examination techniques, have made diagnostic radiology the most widely used medical imaging technology. Diagnostic imaging growth can be seen throughout the healthcare sector, including orthopedic and vascular imaging, plus full-body scanning. This will be a continuing trend, thanks to a shift in focus to more advanced healthcare globally.

As X-ray examinations increase, there is a higher risk of patient and staff exposure to levels of X-ray radiation that could result in negative health implications. As a long-standing member of, among others, IEC, AAPM, and MITA, we are proud to participate in work to research, develop and evolve diagnostic radiology standards. A key company-wide goal is also to educate customers and partners, sharing our deep knowledge of X-ray QA best-practice to protect patients and staff in an ever more complex operational environment.

Our QA solutions are used worldwide by hospitals, manufacturers of X-ray equipment, service providers, and government authorities, across all different modalities, including Rad/Fluoro, Dental, CT, Mammography, interventional, and surgery (C-arms).

Today, we are represented globally through offices in Europe, the USA, and Asia, as well as by 100 distributors worldwide.
