ANALYSIS SOFTWARE
Automated determination of threshold contrast
The CDMAM 4.0 phantom has been specially designed for automatic image scoring.
For analysis of the phantom images we have developed CDMAM 4.0 Analyser software, based on CDCOM for CDMAM 4.0.
With the analyser software the threshold contrast thicknesses are determined according the Supplement to the European Guidelines fourth edition Diagnosis.
