Dynamic x-ray imaging systems used in medicine : quality control in performance characteristics /

This book is intended to facilitate the testing of dynamic imaging systems to ensure safety of the systems. The aim is to discuss methods and techniques that may be used to commission and perform quality control (QC) measurements of dynamic x-ray imaging systems; the primary function of which is rea...
