Introduction:

In the medical imaging sector, core upstream components and certain high-end parts are still predominantly supplied through imports. Among these, the greatest technological gap exists in the CT field, where the technical barriers to entry for CT X-ray tubes are the highest. In 2020, driven by strong demand stemming from the COVID‑19 pandemic, China’s CT market reached RMB 17.27 billion; it is projected to grow to RMB 29.05 billion by 2030, with a compound annual growth rate of 5.3%.

As one of the core components of a CT scanner, the X‑ray tube assembly is essentially a high‑consumption item. Consequently, the size of the X‑ray tube market hinges on the extent of CT adoption and its clinical applications, directly impacting CT system quality, diagnostic performance, and service life. To address the bottleneck challenges facing high‑end imaging equipment and break through technological blockades, the state has adopted an approach that tackles problems as they arise during development—starting with enhancing equipment performance, quality, and reliability while simultaneously overcoming hurdles in critical component manufacturing—thereby fostering a sustainable development framework for both the present and the future.

The rapidly growing CT tube replacement market

Under a series of favorable policies, the import substitution process for medical imaging equipment has steadily accelerated. The localization of CT X‑ray tubes is reshaping both the domestic CT system market and the CT replacement market, with the latter experiencing particularly pronounced shifts. As a core component of CT scanners, the production and development of X‑ray tubes are inextricably linked to the integration with the overall CT system; consequently, the upstream segment of China’s medical imaging industry is entering an accelerated phase of domestic substitution.

As a “dark horse” and a rising force in the CT X-ray tube industry, Zhishu Technology may have started later than its peers, but thanks to its independent R&D of core components—liquid-metal bearings—it has successively launched a range of CT tube replacement products, including the 3MH, 4MHU, and 5MHU series. Moreover, with efficient, precise, professional, and comprehensive after-sales service, the company has swiftly established a nationwide service and sales network, extending value to a broader audience and delivering sustained growth.

Zhishu Technology’s product lineup spans entry-level models, mainstream offerings, and cutting-edge, high-end/ultra‑high‑end CT scanners, covering the entire spectrum of the market. On April 27, the company held a launch event for what it claims is China’s first liquid‑metal bearing–based CT X‑ray tube. Thanks to its innovative products, robust service support, superior quality, and reliable service life, the company has quickly drawn significant industry attention and widespread acclaim.

• The main advantages of Zhishu liquid-metal bearings are:
• Low wear, low vibration, low noise
• High heat dissipation rate, high thermal capacity, excellent stability, and clear imaging.
• It can operate continuously with virtually no impact on service life and almost no startup delay.
• It can withstand higher centrifugal forces (by increasing the CT scanner’s rotation speed).
• Long service life and low maintenance costs

SmartShooting Imaging Joint Escort

As China’s healthcare system continues to deepen and improve, and with the support of national policies promoting the localization of core components, since the launch event for its new products, ZhiShu has already engaged in numerous initiatives and established substantive collaborations with major equipment manufacturers.
These include domestic full‑system manufacturers such as Kuanteng Medical, Sinoway Sheng, Kaiying Medical, Boying Medical, and Wandong Medical, which have established collaborations and engaged in in-depth discussions regarding custom‑designed X‑ray tubes.
Meanwhile, United Imaging Healthcare, Neusoft Medical, and Mingfeng Medical have also commended Zhisu Technology’s breakthroughs and achievements in liquid-metal bearing technology, while expressing strong recognition and ongoing attention to its industrialization efforts and pipeline products.
