|Estimation of breast density using radio wave radar imaging techniques|
The methodology has been tested using clinical bilateral data from 57 patients with known tissue properties (25 with lucent tissue and 32 with dense tissue), leading to a population of 114 breast scans, 64/50 symptomatic/non-symptomatic. Symptomatic here includes breasts with an inclusion e.g. cyst, cancer. It was found important to account for breast size, results demonstrated here are all from a single measurement cup size of approximate volume of 460 ml.
Fig. 5 shows the classifier applied to the non-symptomatic cases. In total 76% of cases were classified correctly. Except for a single outlier in each case BIRAD groups a and d were otherwise classified correctly. As expected, groups b and c were not as easy to classify though this might be a result of error in clinical BIRAD density estimation. When evaluating both symptomatic and non-symptomatic breasts 70% of the cases were correctly classified.
