in developing nanotube based multi-beam X-ray (MBX) tubes
We do not follow, We revolutionize!
Techniques of X-ray sources have remained unchanged. Not anymore.
VEC Imaging is changing the way we look at nanotubes, compared to conventional CNTs. With innovative processes and materials we have addressed the numerous issues existing with todays current CNT standards and have designed an integrated system complete with NT based X-ray tube, associated Control Electronics and High Voltage Power Supply.
We are leading the way from traditional CT Scanners to Portable CT Scanners with Static Gantry.
Nanotube technology with high speed and quality
Our revolutionary (MBX) tube presents unprecedented scanning speed and significantly improved image quality.
It has a wide range of applications from medical imaging to security screening.
The VEC Imaging nanotube uses a nanotube-based, electron field emission emitter (cold cathode) instead of the traditional thermionic emitter (W filament). This new nanotube emitter is a cold emitter that emits electrons at room temperature when driven by an electric field (voltage). It is this nanotube cold emitter technology that finally makes it possible to pack tens or even hundreds of emitters inside a vacuum enclosure without any issue of thermal breakdown.
- Field emission: local electric field strength high enough to extract electrons from emitters
- 2 conductors (C, G)
- No thermal risks
- No inherent limit on packing density
Traditional Gridded Cathode
- Thermionic emission: heat up tungsten filament to release electrons
- 3 conductors (C, F, G)
- Cathode thermal risk: CTE mismatch, evaporation, leakage current, etc.
- Limited packing density for distributed source
