Louvain-la-Neuve, Belgium, 21 March 2026– IBA (Ion Beam Applications S.A., EURONEXT), the world leader in particle accelerator technology and a global provider of dosimetry and quality assurance (QA) solutions, announces the launch of myQA MatriXX AiR, a high resolution, wireless 2D ionization chamber array designed for patient specific quality assurance (PSQA) in particle therapy, including proton and carbon ion treatments. This new solution further demonstrates IBA’s role as a driving force in innovation and reinforces its leadership in quality assurance for particle‑beam therapies.

In radiation therapy, quality assurance is the critical safeguard that ensures increasingly complex treatments are delivered exactly as planned, translating technological innovation into clinical confidence and patient safety.

As particle therapy expands worldwide, proton and carbon‑ion centers are adopting increasingly advanced treatment modalities—from high‑precision conformal therapies to emerging beam‑delivery techniques such as FLASH and ARC radiotherapy. These innovations accelerate clinical potential, but they also elevate the need for robust, future‑proof quality assurance. With myQA MatriXX AiR, IBA sets a new industry standard as the first QA solution capable of providing full patient‑specific verification across both established particle‑therapy treatments and next‑generation delivery modes. This is not an adaptation to change—it is a decisive step forward, positioning IBA as the only partner offering uncompromised QA readiness for the future of particle‑beam therapy.
Engineered specifically for the demands of modern particle therapy, myQA MatriXX AiR features 1,521 high resolution air‑vented ionization chambers and delivers a complete 2D dose distribution readout within seconds, enabling fast and reliable verification of increasingly complex treatment plans. As treatment techniques become more complex, this level of detail directly translates into greater confidence, higher patient safety, and more reliable plan approval.

As the first commercially available wireless detector array for particle therapy PSQA, MatriXX AiR simplifies setup, reduces QA time, and integrates easily into existing workflows. The system is also FLASH‑ready, with hardware designed to support ultra‑high dose rate measurements as clinics prepare for next‑generation radiotherapy techniques.

Commenting on the solution Dr. Loïc Grevillot, Deputy Head of Medical Physics at the MedAustron Ion Therapy Center, stated: “We have been pleased to test the latest MatriXX detector from IBA Dosimetry, which offers a user-friendly interface and — most importantly for our needs —compatibility with carbon ion beams. The detector has demonstrated robust performance in dose evaluation and shows potential for clinical implementation in carbon ion therapy beam delivery QA and PSQA workflows.”
