1. A system to detect an abdominal aortic aneurysm in a region of interest comprising: an ultrasound transceiver configured to deliver ultrasound energy and receive echoes of the ultrasound energy across a plurality of scan planes from the region of interest within which an abdominal aortic aneurysm potentially exists; a processing device configured to signal process the received echoes, characterize the signal-processed echoes across the plurality of scan planes, and detect from the signal-processed echoes an abdominal aortic aneurysm, wherein a percentage of availability of scan planes is calculated based on echoes received from scan planes, the processing device further configured to calculate positioning information of the ultrasound transceiver from the percentage availability; and at least one display configured to present a visual depiction of the percentage of availability of the region of interest contained in a plurality of scan planes, the at least one display configured to present the positioning information of the ultrasound transceiver.
