A set of X-ray test objects for image quality control in digital subtraction fluorography. II: Application and interpretation of results.
In the previous article we introduced a set of test objects for quality control of digital subtraction fluorography (DSF) systems. These test objects have been evaluated using several commercial DSF systems in their clinical environment. In this second article we present test images and results obtained during these trails and explain how the test objects can be used to analyse the imaging performance of DSF systems.
