Abstract: Ultrasound imaging has the advantages of being a real-time, multiplanar, nonionizing radiation imaging technique. However, the technique is limited by operator dependence [1, 2]. While other imaging modalities such as computed tomography, magnetic resonance imaging, and nuclear medicine adjust parameters to improve image quality and diagnostic information, these are usually standardized and programmed before the start of the examination. These parameters are used without change throughout the data acquisition. However, in ultrasound, the interaction of the sound beam with the patient varies significantly throughout the course of a standard examination.
