Abstract:
1. A method of obtaining imaging data for rendering a 3-d image using a capacitive microfabricated transducer array having a plurality of transducer elements, and a plurality of transducer sub-elements within each transducer element that correspond to a plurality of elevation apertures, wherein adjacent sub-elements within the plurality of transducer elements correspond to the same elevation aperture and wherein each transducer sub-element includes at least one transducer cell, the method comprising the steps of: selecting at least one of the plurality of elevation apertures; scanning the transducer array at the selected one elevation aperture, the step of scanning including: repeating the steps of selecting and scanning for a plurality of different elevation apertures in order to provide the imaging data required for rendering of the 3-d image.
