Best Imaging Diagnostics Companies in United States
The 301 best Imaging Diagnostics companies in United States in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Auris Health.
Ranked by disclosed equity funding and recent funding momentum, this directory covers 301 Imaging Diagnostics companies across the United States, tracking $3.9 billion in total disclosed capital. No unicorns yet. But the underlying market tells you why the money keeps arriving: the global imaging diagnostics sector was valued at roughly $30.4 billion in 2022 and is forecast to reach $53.4 billion by 2028, a 5.7% CAGR driven by chronic disease prevalence and an aging population that simply needs more scans.
The funding distribution here is uneven, and I think that's the interesting story. Exo leads the directory at $346 million raised, a figure that dwarfs the next tier. Promaxo sits at $72 million, Ionetix at $61 million, and OXOS Medical and Perceptive IO each at $45 million. So who's actually moving the needle at scale? Government-backed capital is a real force in this space, with HHS, America's Seed Fund, and the National Science Foundation among the most active investors, suggesting early-stage bets on infrastructure and access rather than pure commercial plays. Coverage across the sector is rising, and the companies gaining momentum are the ones building for a market that's structurally larger every year.
