The rapid development of digital imaging and computers networks, using Picture Archiving and Communication Systems (PACS) and DICOM compatible devices increase requirements to the quality control process in medical imaging departments, but provide new opportunities for evaluation of image quality. New StatPhantom software simplifies statistical techniques based on modern detection theory and ROC analysis improving the accuracy and reliability of known methods and allowing to implement statistical analysis with phantoms of any design. In contrast to manual statistical methods, all calculation, analysis of results, and test elements positions changes in the image of phantom are implemented by computer. This paper describes the user interface and functionality of StatPhantom software, its opportunities and advantages in the assessment of various imaging modalities, and the diagnostic preference of an observer. The results obtained by the conventional ROC analysis, manual, and computerized statistical methods are analyzed. Different designs of phantoms are considered.
