What Catalyst MedTech does

Catalyst MedTech (legal entity TTG Imaging Solutions, LLC) is a Pittsburgh-headquartered, privately held multi-vendor OEM and clinical solutions platform serving the U.S. nuclear medicine and molecular imaging market. Founded in 2004 by Jack Tomayko and acquired by Sentinel Capital Partners in December 2021, the company rebranded from TTG Imaging Solutions to Catalyst MedTech in January 2025. It operates three integrated service lines: Equipment Solutions (new OEM and ISO-refurbished nuclear medicine and molecular imaging equipment, anchored by the Digirad solid-state camera portfolio and expanded in April 2026 with the acquisition of Denmark-based X3D ApS, adding CorCam cardiac SPECT and QuantumCam gamma camera systems); Service & Maintenance (nationwide field service with 80+ engineers, ISO 13485:2016 certified, 10,000+ parts SKUs across three climate-controlled warehouses, and multi-year service agreements); and Clinical Solutions (the DIS division, delivering Mobile Nuclear Cardiology on Digirad Cardius cameras, Fixed-Site Cardiac Imaging, Ultrasound, Full Access Neurology for brain PET, and DIS Select turnkey nuclear lab packages bundling equipment, certified staff, radiopharmaceuticals, licensing, and accreditation).

The company employs between 501 and 1,000 people, including approximately 175 nuclear medicine technologists deployed nationwide, and serves hospitals, imaging centers, healthcare systems, cardiology practices, neurology practices, and physician offices. It also operates two partner programs — Propel (OEM enablement, providing service, warehousing, and dispatch to medical imaging OEMs such as Arineta, Epica, and Cablon Medical) and Connect (clinical collaborator enablement, anchored by Algernon Pharmaceuticals for Optimized Brain PET). Catalyst holds exclusive U.S. distribution rights for the CareMiBrain ultra-high-resolution dedicated brain PET system from MindView/OncoVision (sub-1.6mm spatial resolution, paired with Syntermed NeuroQ4 quantification software) and has launched a proprietary Nuclear Medicine Technologist Program with Westmoreland County Community College to address industry-wide staffing shortages. Revenue is generated through a mix of equipment sales, recurring service contracts, parts distribution, turnkey clinical services, OEM manufacturing, and exclusive product distribution, with customers reached via national field sales, inside sales, OEM channels, and international distribution (AccesoFarm in Mexico).
