What Radiation Physics Inc does

Radiation Physics Inc, operating under the trade name PDI Health (and related to Preventive Diagnostics), is a U.S. mobile diagnostic imaging services company headquartered in Hollywood, Florida. The company delivers hospital-grade mobile X-ray, ultrasound, EKG/cardiology, vascular imaging, and vascular access (PICC line) services directly on-site at long-term care facilities, correctional facilities, and at-home patients via fully portable diagnostic units. Every exam is interpreted by board-certified radiologists, and all workflows are described as HIPAA-compliant for integration with existing facility systems.

The company operates a sales-led go-to-market motion, processing orders through a dedicated online portal (House Exam and Facility Exam forms), downloadable PDF order forms, email submission, and a facility login portal for existing clients. It currently serves 11 U.S. states — Connecticut, District of Columbia, Delaware, Maryland, Minnesota, Florida, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, and Virginia — with publicly listed expansion plans to 21 additional states including California, Texas, Georgia, North Carolina, and Tennessee. Revenue is generated on a per-exam basis across three primary customer segments: LTC facilities and senior living communities, at-home concierge patients, and correctional facilities.

The company is privately held, employs 11 people, and has no disclosed funding rounds, revenue figures, or senior leadership team. Its marketing is primarily digital — website-driven with location-based SEO pages targeting geographic search queries — and it is actively recruiting field technicians (X-ray, cardiac, ultrasound) and customer service staff to support expansion.

Direct peers

• MobileXUSA: National mobile diagnostic imaging company specializing in portable X-ray, ultrasound, and EKG delivered to LTC facilities, correctional institutions, and homebound patients. Same core offerings and customer base as PDI Health.
• TridentCare (Modivcare): One of the largest US mobile diagnostic imaging providers, offering mobile X-ray, ultrasound, EKG, and related services to LTC facilities, correctional facilities, and home health patients. Directly comparable service mix, target verticals, and on-site delivery model.
• DMS Health Technologies: Mobile diagnostic imaging provider delivering X-ray, ultrasound, EKG, and cardiac diagnostics on-site to healthcare facilities across multiple US states. Closely aligned service portfolio and geographic rollup strategy.
• Dynamic Mobile Imaging (DMI): Regional mobile diagnostic imaging company serving LTC, home health, and correctional markets with portable X-ray and ultrasound. Competes head-to-head with PDI Health in overlapping geographies and verticals.

Broad incumbents

• RAYUS Radiology: Large national diagnostic imaging network operating both fixed-site centers and mobile service lines across the US. A broader incumbent with overlapping imaging capabilities but a much wider service portfolio.
• Akumin: National outpatient and mobile diagnostic imaging provider with fixed imaging centers and on-site service offerings. Broader incumbent operating in adjacent imaging categories at greater scale.
• SimonMed Imaging: One of the largest outpatient diagnostic imaging networks in the US with broad modality coverage. Fixed-site incumbent rather than mobile specialist, but competes for the same downstream imaging spend.

Emerging players

• Corazon Health Services: Smaller mobile cardiovascular and vascular imaging provider serving LTC and home health patients. Focused subset of PDI Health's vascular/cardiology offering, useful as a partial competitor.
• DispatchHealth: In-home acute care provider that is expanding into on-site diagnostics and point-of-care imaging for homebound patients. Adjacent business model (care delivery to the home) and overlapping home-health customer segment.

Others

• Amedisys: National home health and hospice provider that frequently partners with — or contracts mobile imaging vendors for — its homebound patient population. Relevant ecosystem partner and indirect customer for PDI Health's home concierge segment.
