What DETECTOR does

DETECTOR is an Italian medical device company founded in 2009 as a spin-off from the University of Turin, headquartered in Turin, Italy. It designs and manufactures quality assurance (QA) and beam monitoring instrumentation for particle therapy — primarily proton and carbon ion therapy — sold to particle therapy centers, hospitals, and research institutions globally. Core technology is built around a proprietary TERA front-end Application-Specific Integrated Circuit (ASIC) that digitizes ionization chamber signals at the sensor, with sensitivity down to 50 fC, a dynamic range spanning 1 pA to 3 mA, and a sampling rate of 65 kHz per channel. The product portfolio includes transmission ionization chambers (QubeX, Qeye, AQuracy), Faraday cups (NextQ, PinQ, QCup), patient-specific QA devices (Qplus), FLASH-radiotherapy detectors (FlashDose, FlashQ), and customizable Beam Monitor systems, complemented by a browser-based QA Data Management Software (DMS) for trend analysis, raw data export, and report generation.

DETECTOR's commercial model combines direct equipment sales to end-user particle therapy facilities with custom device design and manufacturing services for OEM partners and integrator customers. The go-to-market is high-touch, anchored in scientific and clinical conferences (PTCOG, ESTRO, ASTRO, AAPM) and supplemented by distribution agreements — notably PTW (US market) and Tecnologie Avanzate (European market) — plus co-marketing partnerships with adjacent technology providers such as Leo Cancer Care and Cosylab. The company is privately held with nominal share capital of €20,000, holds ISO 9001 and ISO 13485 certifications, and has disclosed more than a dozen reference installations including Mayo Clinic, MedAustron, PSI, CNAO, Clatterbridge, and the Shanghai Proton and Heavy Ion Center (SPHIC).

No externally disclosed revenue, funding rounds, or valuation data are available in the input. The company is small (11–50 employees) and operates in a highly specialized niche with limited global addressable market (estimated ~100 particle therapy facilities worldwide), implying a concentrated but high-value customer base and long enterprise sales cycles.

Scale indicators4 records

Recent moves7 records

Expansion highlights6 records

Direct peers

• Standard Imaging: Standard Imaging manufactures QA instruments and phantoms used in radiation oncology, including detectors and electrometers for advanced modalities. It overlaps directly with DETECTOR's ionization-chamber and electrometer-style QA products sold to radiation therapy centers.
• PTW (Physikalisch-Technische Werkstätten): PTW is the global leader in radiation dosimetry and quality assurance for radiotherapy and particle therapy, offering ionization chambers, detectors, and QA software. It is the most direct head-to-head competitor to DETECTOR and is also DETECTOR's US distribution partner, making it both a competitor and channel partner.

Broad incumbents

• Elekta: Elekta is a global vendor of linear accelerators and radiation therapy solutions, including QA software and instrumentation. It is a broad incumbent in radiotherapy that competes indirectly for QA and treatment-planning budgets at cancer centers.
• IBA (Ion Beam Applications): IBA is the world's largest proton therapy equipment manufacturer and also sells complementary QA/dosimetry solutions through its IBA Dosimetry business. It competes with DETECTOR in particle therapy QA and benefits from bundling QA with its own proton therapy installations.
• Varian Medical Systems (Siemens Healthineers): Varian, now part of Siemens Healthineers, is a dominant radiation oncology equipment and software vendor with its own QA ecosystem for proton and photon therapy. It represents the scale incumbent that DETECTOR's specialized products must coexist with in proton centers.
• Sun Nuclear (Mirion Medical): Sun Nuclear, part of Mirion Medical, is a major radiation therapy QA vendor with a broad portfolio of detectors, phantoms, and patient QA systems. It is an established incumbent with deeper resources and broader modality coverage than DETECTOR.

Emerging players

• Leo Cancer Care: Leo Cancer Care is developing upright radiotherapy and proton therapy positioning systems and has co-marketed with DETECTOR. It is comparable as a co-marketing partner targeting the same particle therapy and advanced radiotherapy customer base.
• ProTom International: ProTom International builds compact proton therapy systems for single-room installations, typically in research and clinical settings. It is comparable because its customer base (proton therapy centers) overlaps with DETECTOR's target market for QA devices.

Regional players

• Mevion Medical Systems: Mevion designs and manufactures compact proton therapy systems, primarily for the US market. As a proton therapy equipment vendor, it is a customer-adjacent peer whose installed base represents potential demand for DETECTOR's QA and beam monitoring devices.

Others

• Cosylab: Cosylab provides control system software and integration for particle therapy and large physics facilities. It is a strategic partner of DETECTOR for turnkey nozzle solutions and is adjacent as a complementary vendor rather than a direct QA competitor.
