The position and speed of the transducer is regulated automatically, whereas the angle of incidence and the amount of pressure applied is set by the human operator.
[1] The resulting image data can be read at any convenient time by the radiologist, who is freed from performing the scan.
AWBU has been proposed as an additional cancer screening modality, in particular for women with dense breasts.
[2][3][4][5][6] Studies have consistently shown an increased detection of breast cancer by supplementary ultrasound screening, compared to mammography alone.
[6] AWBU offers advantages in terms of speed and standardization of ultrasound imaging, rendering the result largely independent of the skill of the operator.
