Abstract:
A method for disentangling sample properties in a scanned sample, said method comprising:scanning a calibration sample, said calibration sample having a first property and a second property which are variable; recording values representing a first measured variable and a second measured variable for the calibration sample during the scan; making quantitative measurements of the sample properties of interest at a plurality of points across the calibration sample; using the quantitative measurements to mathematically generate conversion functions which take the first measured variable and the second measured variable as input, and have values representing the first property and the second property as output; scanning an unknown sample for which the first property and the second property are unknown, and measuring the first variable and the second variable for the sample during the scan; and using the conversion functions combined with the measured first variable and second variable for the unknown sample to compute the first property and the second property for the unknown sample.
