Abstract: Systems of generating and manipulating an ultrasound beam are disclosed. The system uses selective sets of ultrasound elements to generate an ultrasound beam, scanning the beam over a series of ultrasound elements in order to collected echo data covering an area, and generating an image from the resulting data. The scanning process includes shifting the set of ultrasound elements used to form the ultrasound beam by more than one ultrasound element (block-switching) between each step in the scanning process. This is accomplished without loss of image resolution by using area-forming techniques. The block-switching technique enables use of cross-correlation methods during image construction.

Abstract: An ultrasound imaging device comprising a two-dimensional array of ultrasound transducers cablelessly coupled to a signal generating and receiving unit such as a motherboard. The coupling includes an acoustically attenuating and electrically conductive structure, which can include posts that are electrically conductive or electrically insulative having a conductor embedded or mounted on the outer surface. There can also be a high density connector allowing coupling and de-coupling the two dimensional array to and from the motherboard.

Abstract: An acoustic lens having two or more regions, each region having a different acoustic index of refraction. The lens may have a simple, non-compound, surface in which both regions form different sections of the same convex or concave curve with the same functional dependence. The transition between the two regions may be gradual or abrupt. The attenuation and other characteristics of the lens may be tailored to provide apodisation and to filter out unwanted frequencies.

Abstract: A surface acoustic wave filter has a Lithiumniobate substrate of parallelogram configuration, which is bonded to a header having similar acoustic impedance. The substrate has three transducers arranged along its long sides at particular spacings destined to suppress triple transit echoes. The short sides are oblique and surface portions adjacent thereto are covered by surface waves attenuating paddings. Two such filters are cascaded on the same header.
