X-ray Inspection System

DualX [Dual Energy]
This product has been discontinued
The DualX analyzes two X-ray signals – both a high and low energy – for a higher detection rate of low-density items, as well as contaminants not previously detectable by standard X-ray systems.

Principle and features of dual energy sensor system

Different materials have varying energy-dependent x-ray attenuation coefficients. X-ray images acquired at high energy and low energy will exhibit different attenuation characteristics.

X-ray energy / Attenuation coefficient

The x-rays generated from an x-ray inspection system have several energy levels. The dual energy inspection system produces two different images from two different energy x-rays simultaneously.

The dual energy inspection system

High energy x-rays produce a brighter image and low energy x-rays produces a darker image. By subtracting the two images acquired at different energies, the system eliminates an image having the same gray level, leaving only contaminants.

Dual energy subtraction better highlights contaminants

The dual energy technology delivers the following unique features compared to conventional X-ray technology:
(1) Low density items can be detected.
(2) Even overlapping products can be inspected without false rejecting.
