x-ray generation
Traditional Thermionic Tube Vs
Nano Electronic X-Ray (NEX Technology™)
OLD
- Heated tungsten filament cathode emits streams of electrodes which accelerate into the anode.
- The impact on the anode generates massive heat and x-rays.
- The heat generated adds complexity:
- needs cooling – a rotating anode, oil bath, lead casing
- adding weight.
- Anode and cathode are at very high voltage.
- Need ramp-up time to switch x-rays on and off.

NEW
- Cold cathode carbon nanotubes emit a precisely controlled electron stream to anode.
- The impact on the anode, produces x-rays.
- Low heat enables simplification of tube, improving efficiencies:
- no rotating anode or oil bath
- light weight due to reduction in size.
- Cathode is at 1-2kV.
- X-rays can be switched on and off instantaneously with no ramping up time.

The Micro-X patented procedure of creating electrons with Carbon Nanotubes is called Nano Electronic Xray Technology, or NEX Technology TM

Thermionic vs Electronic (NEX Technology)


NEX TECHNOLOGY™
The next generation of Imaging
Micro-X has created proprietary Intellectual Property (IP) for the design and manufacture of electronic x-ray tubes, based on Carbon Nanotubes (CNT). We are calling this the Nano Electronic X-ray (NEX) Technology.
Micro-X is the first company in the world to introduce NEX Technology into medical imaging systems. NEX Technology is a simple, non-glass based x-ray tube, with no moving parts that generate minimal heat with no oil required for cooling. It uses carbon nanotubes to offer full medical imaging performance, in a smaller, lighter, and more reliable x-ray tube.
Micro-X’s patented technology is set to revolutionalize the potential of x-rays in a variety of industries and is currently being used as a development platform for all of our future products.


Nano Electronic X-ray (NEX) Tubes are:
- Small & compact
- Lightweight
- Fast & efficient
- Reliable through simplicity
- Precisely controlled
Micro-X First to Market
We are the only company with the NEX Technology, using carbon nanotubes.
- Conventional scaling of field-emission devices hits a ceiling at low current (around 2mA)
- Scaling of medical applications (100mA+) requires a leap beyond conventional field-emission
- Micro-x has patented this "leap"
NEX Technology & ROVER Mobile DR
- Having no motors means less maintenance and breakdowns.
- Very quiet.
- Robust NEX Technology.
- Tubes for Life Warranty.
- Optimizing uptime.
- Through low service overhead.

- Consuming less power.
- Use lithium batteries that are unlikely to need to be replaced – so less land fill.
- Lead-acid Vs lithium-ion batteries — Clean Energy Reviews.
- Taking up less space than traditional systems.

- Light head and arm
- as it is only ¼ the weight of traditional mobile head units.
- Minimizes operator fatigue.
- Wheelie bar to assist with elevation of front wheels in uneven terrain.
- Owing to 4 bar linkage, counterpoise arm.
- Lightweight tube of 2.35kgs and unmotorised arm keeps the device simple.
- Folds away compactly to give great visibility with the arm folded for even the smallest operators.
- Total weight maximum 105kgs.
- Saving time between patients.
- Can be used in any environment where X-ray is needed: hospital, home, special care facilities, transportable.
- For use with adults, pediatrics and neonates.
