Delphinus SoftVue™ ROC Reader Study (DMT SV RRS3)

Study Overview
=================
Brief Summary
-----------------
The purpose of this multi-reader, multi-case (MRMC) reader study is to evaluate reader performance when SoftVue™ automated breast ultrasound and screening mammography are combined, compared to screening mammography alone, in women with dense breast parenchyma. This reader study will include up to 32 radiologist readers and a sample of 140 breast screening cases that were selected from the library of images collected under Delphinus Protocol #DMT-2015.001 (NCT03257839) Arm 1 Phase B. The reader study image case set will be enriched with cancer cases.
