Cloud-native radiology OS unifying PACS, viewing, reporting, worklist and AI
Sirona Medical builds RadOS, a cloud-native radiology operating system that combines diagnostic viewing, reporting, PACS archive, worklist and workflow AI in one zero-footprint Chrome application for radiology practices. The San Francisco company says the platform is AI-native (speech-to-action, pixel-powered reporting) and serves U.S. practices with expanding international availability. In October 2026 it announced a $40M Series D led by Avidity Partners, and publicly states more than $150M raised since inception.
