  3. 3. Assessment of image quality in x-ray fluoroscopy based on Model observers as an objective measure for quality control and image optimization

    University essay from Stockholms universitet/Fysikum

    Author : Henrik Elgström; [2018]
    Keywords : image quality; fluoroscopy; Model observer;

    Abstract : BACKGROUND: Although the Image Quality (IQ) indices calculated by objective Model observers contains more favourable characteristics compared to Figure Of Merits (FOM) derived from the more common subjective evaluations of modern digital diagnostic fluoroscopy units, like CDRAD or the Leeds test-objects, practical issues in form of limited access to unprocessed raw data and intricate laboratory measurements have made the conventional computational methods too inefficient and laborious. One approach of the Statistical Decision Variables (CDV) analysis, made available in the FluoroQuality software, overcome these limitations by calculating the SNR2rate from information entirely based on image frames directly obtained from the imaging system, operating in its usual clinical mode.
