Abstract
A capacitive microfabricated transducer array used for 3-D imaging, with a relatively large elevation dimension and a bias control of the elevation aperture in space and time, confers the same benefits of mechanical translation, except that image cross-sections are electronically rather than mechanically scanned, and are registered very accurately in space. The 3-D cMUT, when combined with elevation bias control and convex curvature in elevation, increases the volume interrogated by the electronic scanning, thus improving field of view. Further still, the 3-D cMUT can be combined Fresnel focusing of the elevation section to improve the elevation focus.
