Image digitalization in radio diagnostics and application in mammography

By Miloš Glatzner


The aim of this study was to analyze issues on digitalization in radiology, especially in mammography. Definition of the separate parts of the diagnostic chain with special accent on mammography imaging with several mammography digitalization designs according to various conditions is stated in the first part of the paper. Comparison between CR and DR systems is then provided in term of patient dose and in term of diagnostic efficacy followed by corresponding conclusions and recommendations. Further is being discussed the methodology of quality assurance in digital mammography. Methodics of single tests is adapted from European guidelines for quality assurance in breast cancer screening and diagnosis [7]. Set of tests enlisted in short-term stability tests national system is selected on the basis of recommended intervals and our specific conditions as described in the paper. Selected test were implemented into „ZPS“ software (VF a.s.) as a new module – digital mammography. This method is supposed to be optimal for a practical utilization, because several radiology departments already use this user friendly software, which also enables to follow the changes in legislation
