Paper Abstract
We designed a Content-Based Image Retrieval (CBIR) Computer-Aided Diagnosis (CADx) system to assist radiologists
in characterizing masses on ultrasound images. The CADx system retrieves masses that are similar to a query mass from
a reference library based on computer-extracted features that describe texture, width-to-height ratio, and posterior
shadowing of a mass. Retrieval is performed with k nearest neighbor (k-NN) method using Euclidean distance similarity
measure and Rocchio relevance feedback algorithm (RRF). In this study, we evaluated the similarity between the query
and the retrieved masses with relevance feedback using our interactive CBIR CADx system. The similarity assessment
and feedback were provided by experienced radiologists' visual judgment. For training the RRF parameters, similarities
of 1891 image pairs obtained from 62 masses were rated by 3 MQSA radiologists using a 9-point scale (9=most similar).
A leave-one-out method was used in training. For each query mass, 5 most similar masses were retrieved from the
reference library using radiologists' similarity ratings, which were then used by RRF to retrieve another 5 masses for the
same query. The best RRF parameters were chosen based on three simulated observer experiments, each of which used
one of the radiologists' ratings for retrieval and relevance feedback. For testing, 100 independent query masses on 100
images and 121 reference masses on 230 images were collected. Three radiologists rated the similarity between the
query and the computer-retrieved masses. Average similarity ratings without and with RRF were 5.39 and 5.64 on the
training set and 5.78 and 6.02 on the test set, respectively. The average Az values without and with RRF were 0.86±0.03
and 0.87±0.03 on the training set and 0.91±0.03 and 0.90±0.03 on the test set, respectively. This study demonstrated
that RRF improved the similarity of the retrieved masses.
