A general understanding of ultrasound physics relative to image optimization is essential when performing breast ultrasound examinations and in accurately interpreting images of the breast. Appropriate technique is crucial to achieve accurate lesion characterization and is emphasized in the second edition of the American College of Radiology Breast Imaging Reporting and Data System for ultrasound (2013). This pictorial essay reviews clinically relevant ultrasound physics to best characterize breast lesions for guiding the clinician to the proper diagnosis. Differences in chosen parameters on ultrasound imaging can create variability in the appearance of breast lesions.
Keywords: breast ultrasound; image optimization; physics.
