Abstract:
A method for obtaining composite data having a data dynamic range from a sample using a scanner which has a scanner dynamic range that is smaller than the data dynamic range, comprising the steps of:(a) using the scanner to scan the sample with a parameter selected at a first value such that the scanner produces valid first data in a first portion of the data dynamic range;(b) using the scanner to scan the sample with the parameter selected at a second value which is different from the first value such that the scanner produces valid second data in a second portion of the data dynamic range;(c) calculating a scale factor correlation function between the first data and the second data;(d) applying the scale factor correlation function to convert the second data to have a same scale factor as the first data; and(e) combining the first data for the first portion of the data dynamic range with the converted second data for the second portion of the data dynamic range to obtain the composite data.
