Ultrasound physics and technology in breast imaging

Ultrasound is used in breast imaging for differentiation of cysts from solid masses and to provide real-time guidance for interventional procedures. Breast ultrasound plays an integral role in evaluating palpable findings, asymmetric breast tissue, and developing densities. Advances contribute to the role of ultrasound in guiding and facilitating minimally invasive procedures. This article briefly reviews some of the hallmarks of modern ultrasound systems relevant to breast ultrasound, discusses recent advances, and outlines how these advances may affect clinical breast ultrasound diagnostic and interventional procedures.
