AI-assisted ultrasound guidance startup Caption Health closes $53M Series B

Brisbane, California-based Caption Health, maker of artificial intelligence-assisted ultrasound guidance software, has tied up a $53 million Series B funding round. Prior backer DCVC headed the raise. Atlantic Bridge and Edwards Lifesciences joined the round as new investors, while Khosla Ventures added onto its previous stake. The company's Caption AI software platform consists of two components, Caption Guidance and Caption Interpretation. The first uses AI to guide medical professionals though cardiac imaging that would normally be conducted by an ultrasound expert.
