What QRM does

QRM (Quality Assurance in Radiology and Medicine GmbH) is a German manufacturer of physical phantoms used for calibration, performance testing, and quality assurance of medical imaging systems, headquartered in Möhrendorf, Germany. The company operates as a wholly-owned subsidiary of PTW Freiburg, which handles worldwide sales distribution while QRM retains product design, manufacturing, and R&D at its headquarters. QRM serves hospitals and medical imaging centers, academic and medical research institutions, medical device OEMs, and—to a lesser extent—industrial non-destructive testing (NDT) users.

QRM's technology centers on proprietary tissue-equivalent materials that replicate human tissue X-ray attenuation properties. Its flagship CTwater material exhibits the same X-ray attenuation as liquid water within ±5 HU accuracy across the 80–140 kV tube voltage range, and ICRU-compliant tissue-equivalent materials simulate lung, bone, and brain tissue. The modular D100 insert system allows interchangeable imaging inserts across multiple semi-anthropomorphic body phantoms (Thorax, Abdomen, Oval Body), and specialized iodine and calcium hydroxyapatite (CaHA) inserts support emerging multi-energy and photon-counting CT protocols. The catalog spans image quality phantoms, anthropomorphic phantoms, bone densitometry phantoms (including the European Spine Phantom, an established BMD QC standard), micro-CT phantoms, dosimetry phantoms, and electron density phantoms for radiation therapy planning.

The business model is hardware sales-led. QRM generates revenue from three streams: standard catalog phantoms, fully customized phantom development for OEM and research customers, and OEM-specific products for medical and industrial X-ray equipment manufacturers. Pricing is quote-based with no public disclosure, and contracts may run multi-year. Distribution combines PTW's global sales infrastructure with direct engagement from QRM's headquarters, supported by a website catalog, technical webinars, downloadable documentation, and trade-show presence. The recent launch of multi-energy and photon-counting CT phantoms, plus credit card payment acceptance in May 2025, indicate ongoing product and commercial expansion.
