Optimal scan plane selection for organ viewing

Abstract

The present disclosure describes an ultrasound imaging system configured to identify a scan line pattern for imaging an object or feature thereof. The system may include a controller that controls a probe for imaging a volume of a subject by transmitting and receiving ultrasound signals in accordance with a plurality of scan line patterns. One or more processors communicating with the probe may generate a plurality of image data sets based on the signals received at the probe, each data set corresponding to a discrete scan line pattern. These data sets are assessed for a target characteristic specific to the object targeted for imaging. One the data set that includes the target characteristic is identified, the one or more processors select the scan line pattern that corresponds the identified image data set. This scan line pattern may then be used for subsequent imaging of the volume to view the object.
