CNT Cold Cathode X-ray Tubes
Next-Generation
X-ray Tube Technology
Enabling safer, more advanced medical diagnostic systems, security screening devices, and non-destructive testing systems.
Reduced Radiation Exposure
Fast response emits X-rays only when needed, cutting unnecessary exposure.
Low Heat & Energy
No filament heated to ~2000 °C, so operating energy and heat generation stay low.
Precise Dose Control
X-rays are generated by applying voltage to carbon nanotubes, allowing accurate dose control.
High Stability
CNT thin-film cathodes deliver high-dose emission while operating stably at high voltage.
Technology
CNT Cold Cathode X-ray Tube
We've been developing CNT-based cold cathode X-ray tube technology to replace conventional hot cathode X-ray tubes and enable next-generation X-ray systems. This innovative technology offers low radiation exposure, low heat generation, and precise dose control.
