Technology
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.
Conventional hot cathode X-ray tubes generate X-rays by heating a tungsten filament to around 2000°C. However, their slow response time can result in unnecessary radiation exposure, and their high power consumption further limits their use in portable/mobile and fluoroscopic X-ray imaging systems.
The new type of cold cathode X-ray tubes, which generate X-rays by applying voltage to carbon nanotubes, offer reduced unnecessary exposure, low operating energy, and precise dose control. In particular, LMX's cold cathode X-ray tubes, based on a carbon nanotube thin film, deliver high-dose X-ray emission while maintaining stability under high voltages.
| Hot cathode | LMX cold cathode | |
|---|---|---|
| Electron source | Tungsten filament heated to ~2000 °C | Carbon nanotube thin-film field emitter |
| Operation | Slow response time | X-rays generated by applying voltage to CNTs |
| Radiation exposure | Unnecessary exposure from slow response | Reduced unnecessary exposure |
| Operating energy | High power consumption | Low operating energy |
Applications
LMX's cold cathode X-ray tubes are well-suited for use in portable and mobile diagnostic X-ray devices, diagnostic fluoroscopy systems, dental and medical CBCT equipment, security screening systems, and nondestructive testing (NDT) applications.
