What IRT Systems does
iRT Systems GmbH is a privately held German medical device manufacturer founded in 2012 and headquartered in Koblenz, Germany, with a US subsidiary (iRT Systems Corporation) in Clayton, Missouri. The company develops and commercializes the IQM (Integral Quality Monitor), a gantry-mounted transmission ionization chamber that provides fully automated, real-time, segment-by-segment verification of radiation therapy delivery. The technology combines the signal stability of a large ion chamber with the spatial accuracy and sensitivity of film, and it calculates a predicted dose-area product for each beam segment before treatment and compares it in real time to the measured signal during irradiation. IQM holds ISO 13485 (MDSAP) certification, CE marking under EU MDR, FDA 510(k) clearance, and Health Canada approval, and it supports all major photon-based treatment techniques (IMRT, VMAT, SRS, SBRT, DCAT, TBI) on any linear accelerator.
iRT sells IQM directly to radiation therapy clinics and cancer centers and through a strategic partnership with Elekta, where IQM is offered as part of Elekta linear accelerator packages and featured at conference booths. The installed base spans hospitals and academic centers in Germany, Austria, the UK, Spain, Italy, Belgium, Hungary, Slovenia, Croatia, Turkey, the USA, Canada, Japan, South Korea, and Puerto Rico, with named reference sites including Johns Hopkins, Princess Margaret Cancer Centre, Cedars-Sinai, University of Debrecen, Allegheny Health Network, GenesisCare La Milagrosa, and Teikyo University Hospital.
The company generates revenue from IQM hardware sales, recurring software extensions (Machine QA, Reporter, Custom Field Types, Online Adaptive RT Workflow), installation and training services, and technical support. iRT is led by founder and Managing Director Juergen Oellig and operates with 11–50 employees, with ongoing product development (v1.10 in September 2024 and v1.11 in December 2025) and a recently announced strategic collaboration with C-RAD AB (July 2025) to combine IQM real-time beam verification with surface-guided radiotherapy systems.

IRT Systems competitors and assessment
Company assessmentDirect peers
- PTW Freiburg: PTW is a long-established European manufacturer of dosimetry and QA equipment for radiation therapy and diagnostic radiology, including ionization chambers and detector systems. It is a direct competitor in radiation measurement and QA for the same radiotherapy customer base.
- IBA Dosimetry: IBA Dosimetry is a global leader in radiation therapy patient QA and detector systems, including transmission detectors and dosimetry solutions. It competes directly with iRT's IQM in the same radiation oncology QA category with broader product breadth.
- Standard Imaging: Standard Imaging designs and manufactures QA phantoms, electrometers, and detectors for radiation therapy — competing with iRT in the same customer segment (medical physicists in radiation oncology). Comparable mid-sized medical device competitor in radiation QA.
- Sun Nuclear (Mirion Technologies): Sun Nuclear (now part of Mirion Technologies) is the dominant provider of radiation therapy QA products including ArcCHECK, MapCheck, and Daily QA — directly named alongside IQM in multi-vendor comparison studies at GenesisCare. It is the most direct competitor in patient-specific QA hardware.
- Mobius Medical Systems (Varian): MobiusFX (now part of Varian) is named in iRT customer comparisons and provides software-based patient QA, including log-file and 3D verification. It represents the software-only QA approach competing with IQM's hardware-based verification.
Emerging players
- C-RAD: C-RAD provides surface-guided radiotherapy (SGRT) systems (Catalyst, Sentinel) and is now iRT's strategic partner (announced July 2025) for combined SGRT + in-vivo verification. Previously an adjacent competitor, now a partner — comparable as an emerging technology player in the radiation oncology safety stack.
- LAP Laser Applications: LAP Laser manufactures patient positioning systems and QA phantoms used in radiation therapy, including thorax phantoms (Octavius) referenced in iRT comparison studies. Comparable as a niche QA hardware vendor serving the same radiotherapy physics customers.
- RTsafe: RTsafe provides patient-specific QA using 3D-printed anthropomorphic phantoms for end-to-end testing of radiotherapy treatments — an alternative patient-specific QA approach competing with IQM in the same radiation oncology safety category.
Broad incumbents
- Varian (Siemens Healthineers): Varian is one of the two dominant LINAC manufacturers globally and increasingly bundles QA capabilities (EPID-based, log-file) into its treatment planning ecosystem. It is both a competitive threat and a channel opportunity for iRT outside the Elekta base.
- Elekta: Elekta is the second major LINAC manufacturer and iRT's primary channel partner — IQM is sold as part of Elekta's linear accelerator packages. As a broad incumbent in the radiotherapy ecosystem, Elekta is both iRT's biggest distribution partner and a potential future competitive risk if it internalizes QA.
