Abstract
An ultrasonic diagnostic imaging system and method produce attenuation coefficient maps of a region of interest in an ultrasound image. In order to detect the presence of elevation aperture blockage, the system estimates attenuation coefficients by two different methods. The estimates produced by the two different methods are combined to produce a metric, which is evaluated as a function of depth. If the metric satisfies one or more criteria of measurement bias, elevation aperture blockage is identified and an alert of the blockage is produced for the user.
