Zhishu Technology Shines at CMEF Shanghai: A Breakthrough in Domestic CT X-ray Tube Technology Draws Global Attention

From April 8 to 11, Shanghai became the global hub for medical technology. The 91st China International Medical Equipment Fair (CMEF) kicked off in grand style, with ZhiShu Technology making a stunning debut by showcasing its independently developed portfolio of core CT tube products, drawing widespread attention with its cutting-edge technological prowess. Hundreds of industry experts from leading medical device manufacturers across North America, Europe, Southeast Asia, and China gathered at ZhiShu’s booth, witnessing groundbreaking innovations in domestically produced high-end core components for medical imaging. These new products, sharp and precise, are set to redefine industry trends and inject powerful momentum into the ongoing advancement of the healthcare sector.

Hardcore Expertise: Decoding the Technological Pinnacle of Zhishu’s CT X-ray Tubes

Zhishu Technology continues to ramp up its R&D investment, bolstering its technical workforce, expanding its R&D production‑line equipment, and accelerating the pace of technological iteration, thereby overcoming an increasing number of technical challenges. With breakthroughs across the entire core‑technology spectrum, domestic substitution is gaining momentum. At the exhibition, Zhishu showcased its mid‑to‑high‑end CT X‑ray tube series, which, thanks to liquid‑metal bearing technology, a gradient‑heat‑dissipation design for the anode target, and an intelligent thermal‑capacity management algorithm, delivers key performance metrics on par with leading international brands: average service life surpasses the limits of clinical scanning; anode heat‑dissipation efficiency has been significantly enhanced, supporting continuous high‑load imaging; and milliampere‑second output stability ranks among the industry’s best.

The products showcased this time are the ZS702L X-ray tube and the ZS702L/H847B X-ray tube assembly. This model incorporates Zhishu Technology’s latest liquid-metal bearing technology, which enhances the structural integrity of the bearing stator, optimizes the liquid-metal formulation, and improves operational stability. The anode target diameter reaches 200 mm, with a thermal capacity of up to 7.0 MHU. It offers two focal spot sizes—0.9 × 0.7 mm and 1.2 × 1.1 mm—and a rated anode input power of up to 72 kW. The rotating anode speed can reach 8,400 RPM, supporting a maximum gantry rotation time of 0.35 seconds. This product is compatible with GE OPTIMA series models 620, 660, and 680, as well as REVOLUTION series models MAXIMA, ACE, and EVO and above.

In addition, the ZS712L X-ray tube and the ZS712L/H485B X-ray tube assembly were also on display. This product incorporates an upgraded version of Zhishu Technology’s proprietary liquid-metal bearing technology, which increases the rotational speed of the rotating anode and enhances the bearing’s ability to withstand centrifugal acceleration. The rotating anode can reach speeds of up to 12,000 RPM—currently the highest‑speed anode in China—and supports a maximum gantry rotation time of just 0.33 seconds. Its thermal capacity reaches 7.0 MHU, and its rated anode input power can peak at 75 kW, making it Zhishu Technology’s highest‑power offering to date. It is compatible with complete systems such as Siemens GO ALL, GO FIT, GO TOP, and GO SIM models.

Moreover, to address diverse clinical needs, Zhishu has launched three major product lines—“Precision Diagnostics,” “Emergency‑Room Efficiency,” and “Research Exploration”—which are compatible with high‑end CT systems featuring 64 rows or more, thereby supporting end‑to‑end applications across all settings, from primary care to top-tier tertiary hospitals.

Exhibition Highlights: Global Customers Flock to China’s Smart Manufacturing

At its exhibition booth, Zhishu Technology showcased its comprehensive product portfolio. Through in-depth on-site discussions, the Zhishu team highlighted the superior performance of its liquid-metal‑bearing CT X‑ray tubes, drawing technical teams from Siemens Healthineers, United Imaging, and other leading companies to stop by for exchanges. As a core component of CT scanners, Zhishu Technology is the only domestic company to have achieved mass production of liquid‑metal‑bearing CT X‑ray tubes, and this year’s show further underscored its leading position in the critical components segment of high‑end medical equipment.

International customer feedback: “Zhisu’s liquid‑bearing technology has overcome the longstanding technical barriers of conventional ball‑tube designs, which is of great significance for enhancing CT image quality.” During the exhibition, Zhisu engaged in in-depth discussions with overseas clients; its products are now exported to more than twenty countries, marking a pivotal breakthrough in expanding its international market presence.

Future Outlook: Making Precision Medicine Accessible to All

Zhisu Technology will continue to ramp up investment in cutting-edge R&D, achieving a 95% localization rate for key components. This further ensures independent control over critical parts, providing robust assurance for the reliable and stable operation of CT systems. By collaborating with industry partners, the company is driving cost reduction and efficiency gains in CT equipment, enabling more grassroots hospitals to access high‑performance, cost‑effective imaging solutions.

May we pierce industry barriers like X-rays, keenly seize the opportunities of our era as if we were detectors, and, with the wisdom of reconstructive algorithms, chart a blueprint for win-win outcomes across the sector!
