CNT-based field emission
digital x-ray source
1. Since the X-ray was first discovered by Röntgen approximately 120 years ago, it has significantly contributed to the improvement of human life in many industries. It is a widely known fact that it had a significant impact on the development of the diagnostic imaging equipment industry.
2. These X-ray-based imaging devices consist of two essential elements: an "X-ray source" for emitting X-rays and an "X-ray detector" for detecting irradiated X-rays. Among them, the X-ray detector has already been converted from analog film to digital CMOS and TF. Based on this history, the concept called "digital x-ray image equipment" has begun to be derived.
3. However, the x-ray source still uses filament-based analog systems such as incandescent bulbs, and complete digital X-ray imaging equipment has yet to exist in the world.
4. To “fully control the pulse-shaped X-ray with high speed and accuracy,” which an analog device cannot achieve, VSI invented and commercialized a “CNT-based field emission digital X-ray source” with full digitization for the first time in history. Based on this, VSI is no longer relying on other leaders in the industry. Instead, we are becoming leaders in core X-ray component technology by providing a fully digitized product and expanding X-ray applications in the industry by allowing faster, smaller, more efficient, and higher resolutions.
