Method for checking the presentation quality of imaging systems for medical diagnostics with respect to ring artifacts

A method for checking quality of an imaging system for medical diagnostics with respect to ring artifacts, said method comprising the following steps:

• creating at least one test image;
• defining concentric circles in the at least one test image;
• generating a ring profile from the defined concentric circle;
• detecting ring artifacts in the generated ring profile;
• and
• computing visual signal noise for each ring artifact and comparing the computed signal noise to a pre-selected criterion for evaluating a visual detectability of the detected ring artifacts.

A device for checking quality of an imaging system for medical diagnostics with respect to ring artifacts, comprising:

• a defining device, designed to define concentric circles in at least one test image created by the imaging system;
• an averaging device, designed to average the image points of the test image in order to create a ring profile;
• a detector, designed to detect ring artifacts in the created ring profile;
• and
• a comparator, designed to compare the detected ring artifacts to a pre-selected criterion in order to evaluate a visual detectability of the detected ring artifacts, wherein the comparator is further designed to compute the visual signal noise for each ring artifact in order to compare the computed signal noise to the pre-selected criterion.
