About Us


VEC Imaging GmbH & Co. KG, the world leader in developing nanotube based multi-beam x-ray (MBX) tubes. Since the discovery of X-ray over a century ago, the techniques applied to the engineering of X-ray sources have remained relatively unchanged. Not any more!
VEC Imaging is changing the way we look at nanotubes compared to CNTs. With innovative processes and materials we have addressed the numerous issues with todays current CNT standards and have designed an integrated system complete with NT based X-ray tube and associated Control and Power Electronics. We are leading the way from two dimensional to 3D-Tomosynthesis and full CT, on a dynamic scale.
VEC Imaging is dedicated to developing, producing and selling multibeam nanotube (NT) based X-ray tubes and associated Control and Power Electronics for
Medical, Security and Industrial Applications.


  • Static Breast Tomosynthesis Systems
  • Portable Tomosynthesis Systems
  • C-Arm Systems
  • Portable Computed Tomography (CT) Systems
  • Carry-On Stationary CT-Scanners
  • Checked Baggage Stationary CT-Scanners
  • Backscatter Systems


In support of this business we also develop, produce and sell customized high voltage generators and control electronics for conventional and nanotube based X-ray tubes.

Formed in 2018 and based in Erlangen, Germany, VEC Imaging GmbH, Co. & KG is a Joint Venture between CETTEEN GmbH and Varex Imaging Corporation. CETTEEN GmbH owned the IP’s for NT-Technology, NT based X-Ray Tube Technology, and Control/Power Electronics designed for Medical, Security and NDT applications. Varex, the worldwide leader in x-ray tube components, brought 65 years of x-ray tube manufacturing experience to the joint venture.
VEC Imaging is focused on rapidly commercializing its technology and patents. In addition, we will formalize our US Business Development Center in the United States in 2019, giving us a local presence for US customers.
During the transition period of establishing the Joint Venture, VEC Imaging was able to continue with the creation of our IPs/Patents and in turn move quickly into development. This was made possible by government funding from The Bavarian State Ministry for Economic Affairs, Regional Development and Energy StMWi.

VEC Imaging GmbH & Co. KG is dedicated to developing, producing and selling nanotube based X-ray imaging components and systems to improve healthcare and save lives.
We are committed to
Maintaining consistent quality in our work ethic, standards, customer service and products.
Maintaining our highest business principles for customer satisfaction through continuous improvement.
Encouraging our employees to perform with entrepreneurial thinking to meet our customers requirements and expectations.
Comply with all laws and regulations that govern us and maintain, monitor and improve the effectiveness of our quality management system.

New Materials and Proprietary Processes

for producing high performance field emission cathodes, makes VEC Imaging the World Leader in developing nanotube based multi-beam x-ray (MBX) tubes

VEC Imaging Replaces the traditional coiled filament with nanotube (NT) field emission emitter (Cold Cathode)
Immediate benefits are recognized from this revolutionary change

  • Chemically and mechanically very stable
  • Optimal emission characteristics (low turn-on electric field, high emission current)
  • Cold cathode with no heat generation (high energy efficiency)
  • Ultra fast switching on / off
  • Cost-effective manufacturing


Innovative NT Materials
Moving beyond todays CNT based emission cathodes, we have developed Compound NT containing more than one element. Compared to pure CNT, our compound NT has

  • Improved chemical and thermal stability
  • Better electrical and thermal conductivity
  • Enhanced field emission properties (high emission current and higher emission stability).


New Cathode/Emitter Activation Process
VEC Imaging has taken the cathode activation process to the next level. Our new process is based on curable liquid adhesives, instead of rigid adhesive tape. Our process does not have the issue of being highly sensitive to process parameters that are difficult to control, such as the adhesive strength and applied pressure. Instead we can control the activation results with high accuracy by controlling easily controllable process parameters curing temperature and time.


New Cathode/Emitter Deposition Process
VEC Imaging has developed and patented a Paste and Screen Printing (SP) process for making NT cathodes with high accuracy. This process overcomes critical technical difficulties resulting from the chemical vapor deposition (CVD) direct growth and electrophoretic deposition (EPD) process used today in terms of control, consistency and reproducibility, we have achieved

  • Excellent reliability and consistency on mass production scale
  • Extremely accurate control of average film thickness (± 1.5 µm) within one cathode and among different cathodes
  • Much more uniform and smooth cathode surface (surface roughness ± 3 μm)
  • Improved production yield and reduced material and production costs
