METHOD FOR DETERMINATION OF SPATIAL DISTRIBUTION AND CONCENTRATION OF CONTRAST COMPONENTS IN A POROUS AND/OR HETEROGENEOUS SAMPLE

摘要

A method for determination of a spatial distribution and concentration of contrast components in a porous sample comprises the steps of scanning a sample with X-ray and obtaining a computer tomographic image of the sample. Then an area of interest inside the obtained computer tomographic image is selected and a first cross-section of the computer tomographic image is defined. Spatial distribution and concentration of contrast components inside the area of interest are determined by analyzing histograms of grayness distribution in the cross-sections of the computer tomographic image starting with the reference cross-section.

1. A method for determination of spatial distribution and concentration of contrast components in a porous or/and heterogeneous sample comprising the following steps:
scanning the sample with X-ray, obtaining a computer tomographic image of the sample, defining an area of interest inside the obtained computer tomographic image, defining a reference cross-section of the obtained computer tomographic image, obtaining histograms of grayness distribution in the cross-sections of the computer tomographic image, determining spatial distribution and concentration of contrast components along the sample by analyzing histograms of grayness distribution in the cross-sections of the computer tomographic image starting with a histogram of grayness distribution in the reference cross-section.
