X-ray Dual Energy

X-ray Inspection System
Dual Energy DualX

Analyzing two different x-ray energy signals, it clearly distinguishes contaminants from products. Performs accurate inspection of low density bones in metal and overlapping products.

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.


Dual Energy
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.
Dual Energy
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.


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