NUMERICAL EQUIVALENT OF ACCURACY AS A MEASURE OF MEDICAL IMAGE QUALITY
Abstract
The objective of this study is a proposition for a new vector measure of image quality reflecting diagnostic accuracy. The formation of a diagnostic quality pattern (DQP) was based on the subjective ratings of image local features, playing an essential role in the detection and classification of any lesion. The pattern was used for more reliable calculation of a single number - the equivalent of diagnostically related image quality. The equivalent was constructed with a criterion of the highest correlation with approximated diagnostic accuracy of compressed images. Experimental results contain the opinions of 9 radiologists: 2 test designers and 7 observers who rated digital mammograms. The correlation coefficient between the numerical equivalent of the vector measure and subjective rates is over 0.9.
