Questions from This Article

What is global noise level in CT imaging?
Global noise level is a quantitative measure of noise in clinical CT images, calculated directly from the patient images themselves rather than from phantom studies. It is one of the foundational image quality metrics in radiology and serves as the basis for the CMS proposed image quality measure for diagnostic CT in adults. The technique was developed by Olav Christianson and Dr. Ehsan Samei, whose original research paper underpins much of the current image quality assessment field.
What aspects of image quality should radiology teams measure?
Image quality assessment should cover multiple parameters that affect diagnostic value. Imalogix’s platform tracks five core areas: global noise level (the CMS-proposed metric), patient centering, localizer usage, protocol deviation, and pediatric performance. Each captures a different aspect of how image quality is produced or compromised across the imaging workflow. Looking at any single metric in isolation gives an incomplete picture of clinical image quality.
How does Imalogix advance image quality research?
Through the Duke University Imalogix Fellowship and the Imalogix Research Institute, the company supports research using imaging data from hundreds of participating hospitals. The research focuses on measuring and optimizing clinically important aspects of image quality, including resolution, texture, and contrast. The output of this work has produced peer-reviewed methodologies that feed back into the platform, so commercial customers benefit from current academic research.
