What Diacor does
Diacor Inc. is a privately held medical device company founded in 1983 and headquartered in Mount Pleasant, Utah. The company designs, manufactures, and distributes the Zephyr line of patient positioning and transfer systems used in radiation oncology, interventional radiology, and image-guided surgical procedures. Its core technology is a patented air-driven hoverboard patient transfer system that enables float-based repositioning without manual lifting, with cross-modality compatibility spanning CT, MR, PET, and linear accelerator treatment environments. The company's product portfolio includes Zephyr HDR for image-guided brachytherapy, Zephyr EB for external beam radiation therapy (with XL, HP, and HP PRO variants), Zephyr IR for intraoperative MRI and interventional cardiovascular MRI, Flat Table Top Overlays, MR-tek MR Conditional Stirrups marketed as the world's first MR-conditional stirrups, and the K-tek 250/350/500 conventional stirrup line.
Diacor sells capital equipment to hospitals, cancer centers, and academic medical centers via a distribution model comprising more than 35 global distributors, complemented by a strategic co-development relationship with Philips Healthcare. The company reports ISO 13485:2016 quality certification and CE marking for its regulated devices, with named installations across the United States (John Stoddard Cancer Center, Comprehensive Hematology Oncology, MUSC Hollings Cancer Center, Dana-Farber/Brigham and Women's, University of Rochester Medical Center), Canada (Princess Margaret Hospital), Japan (Teikyo University Hospital), Italy (Reggio Emilia Hospital), and China (Jinshazhou Hospital). Pricing is established through direct quote-based sales of capital systems and accessories rather than disclosed list pricing. Leadership includes Tami Tialavea as Chief Operating Officer.
The business model is a B2B capital equipment sale with global distributor-driven reach, regulatory clearance in major markets, and revenue mechanics dependent on periodic hospital and oncology center procurement decisions rather than recurring contracts.

Diacor competitors and assessment
Company assessmentBroad incumbents
- Brainlab: Brainlab provides integrated surgical and radiotherapy solutions including patient positioning, image guidance, and intraoperative imaging across neurosurgery, spine, and radiation oncology. It competes with Diacor's Zephyr IR for intraoperative MRI workflows and offers broader-portfolio alternatives for hybrid OR buyers.
- Elekta: Elekta is a global incumbent in radiation therapy and neurosurgery equipment, including linear accelerators, brachytherapy afterloaders, and the Elekta Unity MR-Linac. While not a direct positioning-equipment peer, Elekta's integrated MR-guided and adaptive RT platforms compete with workflows that rely on Zephyr for patient transfer.
- Varian (Siemens Healthineers): Varian, now part of Siemens Healthineers, is the dominant linear accelerator and radiation oncology software provider and supplies the Exact Couch Indexing standard that Zephyr integrates with. As a broad incumbent with the resources to bundle its own positioning solutions, Varian is a key indirect competitor and platform partner to Diacor.
Direct peers
- Qfix: Qfix is a direct peer specializing in patient positioning and immobilization devices for radiation therapy, including couch tops, immobilization systems, and motion management. It competes directly with Diacor's Zephyr EB and flat table top overlays in the radiation oncology positioning market.
- CIVCO Radiotherapy: CIVCO Radiotherapy (a division of CIVCO Medical Solutions) provides patient positioning, immobilization, and motion management solutions for radiation therapy, including couchtops, overlays, and SBRT accessories. It is a direct peer to Diacor's positioning and transfer product line in radiation oncology workflows.
- Orfit Industries: Orfit Industries manufactures thermoplastic immobilization masks, vacuum bags, and patient positioning devices for radiation therapy. Although also a Diacor distribution partner, Orfit is a direct peer in immobilization/positioning and competes with Diacor's Zephyr XL HP and accessories line in head/neck and SBRT workflows.
Emerging players
- ViewRay (now ViewRay Systems): ViewRay pioneered MR-guided radiation therapy systems (MRIdian) and drives demand for MR-compatible patient positioning solutions like Diacor's Zephyr. While not a direct positioning competitor, ViewRay's growth directly expands the addressable market for Diacor's MR-conditional transfer and stirrup products.
- Best Medical International: Best Medical International provides brachytherapy accessories, applicators, and patient positioning systems used in gynecologic and prostate brachytherapy. It is an emerging peer competing with Diacor's Zephyr HDR workflow in the same brachytherapy applicator/positioning space.
- Klarity Medical Products: Klarity Medical Products designs and manufactures patient positioning and immobilization devices, including thermoplastics, vacuum bags, and baseplates for radiation therapy. It is an emerging competitor in the same positioning niche as Diacor's Zephyr EB and stirrup product lines, particularly in cost-sensitive markets.
Regional players
- MediPlast / Reuther MedizinTechnik: MediPlast and similar European regional manufacturers supply patient positioning and surgical accessories to European hospitals, including stirrups, table tops, and surgical support devices. They compete regionally with Diacor's MR-tek and K-tek stirrup lines in lithotomy positioning.
