What's the deal? Beijing Zhishu TechnologyDealroom has a profile for this one. Try Dealroom →, a Chinese maker of liquid-metal bearing CT X-ray tubes, has raised more than US$27.5M (≈$29.9 million, FX-converted) in a Series C round announced in October 2026. CICC Capital and Zhejiang Provincial Investment co-led, with Shanxi Securities Innovation joining and existing backers Hongchuang CapitalDealroom has a profile for this one.

What does the company do? Zhishu is China's first firm to reach self-sufficient, large-scale production of liquid-metal bearing CT tubes — a critical, high-barrier component long dominated by overseas suppliers. It holds 28 NMPA medical device registrations covering 16- to 256-slice CT machines and says its products ship to more than 20 countries.
What's the money for? The round funds three priorities: expanding automated production lines; R&D and registration for ultra-high-end CT tubes, DSA tubes, and industrial X-ray sources; and overseas channel building plus FDA and CE certification. The company says it has now entered IPO preparation.
Why now? The raise lands amid a wave of financing for domestic CT tube makers. One 2026 industry review counts three tube companies funded within the year, all pursuing the liquid-metal bearing route — the same path where Zhishu already sat among the better-funded players.
By the numbers: At this size, the round sits around the 56th percentile for deal amount — a mid-pack figure rather than an outlier.
What could go wrong? Figures on capacity, registrations, and market coverage remain company-reported. The real test is whether Zhishu can deliver at scale and match international rivals on reliability and clinical performance.
The signal: "CT tube domestic substitution has entered the second half," chairman Hu Yinfu said (translated from Chinese), arguing competition now hinges on mass-production capability, product range, and global service rather than single technical breakthroughs. The round reflects a sector shifting from proving technology to delivering it at volume.
