Beam hardening manual

The Mpx3GUI application has a built in beam hardening calibration.
To apply this to the image, a number of steps has to be taken. This process will be illustrated below.
More information of the effects and the correction of beam hardening can be found here.


The beam hardening correction uses multiple flat field correction images. These have to be created before the calibration can be applied to the image.
These flat field correction images can be made by placing homogeneous sheets between the X-ray beam and the detector and then making an image.
The voltage and amperage of the X-ray beam have to be identical to the settings used to make the original image.
The material should resemble the material of the original image. E.g. aluminum for bones and glass for tissue.

The images produced this way might look as follows:
