  • Patent number: 8177718
    Abstract: An ultrasonic diagnostic imaging system has a two dimensional array arranged in multiple patches of multiple transducer elements. Each patch of transducer elements is coupled to a group of microbeamformer delay lines having outputs which can be coupled to a selected channel of a system beamformer, which beamforms the partially summed beams of each patch into a final beamformed signal. The ability to direct a delayed signal from a transducer element to a selected beamformer channel enables the patch boundaries to be changed as the aperture is translated across the array.

  • Patent number: 8161817
    Abstract: An ultrasonic diagnostic imaging system has a two dimensional array arranged in multiple patches of multiple transducer elements. Each patch of transducer elements is coupled to a group of microbeamformer delay lines having outputs coupled to a channel of a system beamformer, which beamforms the partially summed beams of each patch into a final beamformed signal. The outputs from multiple patches which are not simultaneously used in the active receive aperture are coupled to a common beamformer channel, enabling the number of patches of the array to exceed the number of channels of the system beamformer without the use of multiplexers.

  • Patent number: 8038618
    Abstract: An ultrasound-imaging system and method is provided that permits an operator to acquire an image of a volume-of-interest in a time critical fashion, that is capable of referencing the volume rendering to a standard two-dimensional imaging mode, and permits the operator to selectively choose a number of display-mode parameters that result in an operator directed view of the volume-of-interest. The ultrasound-imaging system comprises an input device configured to receive a plurality of imaging parameters and a controller in communication with the input device. The ultrasound-imaging system generates an operator-directed transmit-beam scan sequence in response to the imaging parameters and transmits a spatially modified transmit-beam scan sequence over a portion of the volume-scan range of the ultrasound-imaging system. Moreover, the ultrasound-imaging system provides the flexibility for an operator to direct a plurality of operator-configurable multi-dimensional views.

  • Patent number: 7796789
    Abstract: A three dimensional ultrasonic diagnostic imaging system is operated to guide or observe the operation of an invasive medical device (30) in three dimensions. An interventional system (20) is used to operate the invasive medical device (30) and produces spatially-based information relating to the activity of the invasive medical device (30). The spatially-based information from the interventional system (20) is merged into the three dimensional ultrasonic image data to produce a live three dimensional image of the invasive medical device (30) or its activity. In one embodiment the locations where the activity of the invasive medical device (30) is performed is recorded and displayed in the three dimensional ultrasonic image. The three dimensional ultrasonic image may be shown as an anatomical volume rendered image or as a wire frame model (130) of the anatomy. In another embodiment an integrated three dimensional ultrasonic imaging and invasive device system is described.

  • Patent number: 7529393
    Abstract: A three dimensional ultrasonic diagnostic imaging system is operated to guide or observe the operation of an invasive medical device (30) in three dimensions. The invasive medical device (30) is shown in a detailed ultrasonic image and the balance of the volumetric region (120) in which the device is located is shown in a wide field of view. The detailed and wide fields of view may be displayed separately or overlapping in spatial alignment on an image display (18). The wide field of view may be shown in two or three dimensions. A quantified display may be shown together with the wide and detailed anatomical displays. The detailed view may also be shown in an enlarged or zoomed format.

  • Patent number: 7270634
    Abstract: A three dimensional ultrasonic diagnostic imaging system is operated to guide or observe the operation of an invasive medical device (30) in three dimensions. The appearance of the invasive device (30) in the three dimensional ultrasonic image is enhanced to be more readily observable by a clinician. The enhancement is produced by transmitting a greater ultrasonic beam density in a subvolumetric region including the invasive device (30) than in the surrounding portion of the volumetric region (120). The beam density may be uniformly high in the subvolumetric region and uniformly low in the surrounding region, or may taper from a relatively high beam density around the invasive device (30) to a minimum beam density at distances removed from the invasive device (30).

  • Publication number: 20060116584
    Abstract: Ultrasonic transducers having a reduced size in comparison with prior art ultrasonic transducers and including a thermally-conductive body, a flexible circuit bent at least partially around the body, an acoustic assembly arranged on the flexible circuit and electronic components for controlling the acoustic assembly to transmit and receive ultrasonic waves. Signal transmission lines, such as coax wires, are coupled to the flexible circuit such that the electronic components, the acoustic assembly and the signal transmission lines are connected in a circuit defined in part by the flexible circuit. By bending the flexible circuit with the acoustic assembly, and optionally the electronic components, arranged thereon about the body, they are positioned in a vertical configuration which allows for a compact transducer which has a small, even miniature size in comparison to prior art ultrasonic transducers.

  • Publication number: 20050148874
    Abstract: The present invention combines the benefits of aberration correction with the benefits of microbeamforming in an ultrasound diagnostic imaging system, such that both partial beamforming (in the microbeamformer) and at least some part of the phase aberration detection correction processes are accomplished in the transducer probe proximate the transducer array. Accordingly, aberration correction applied at or proximate the microbeamformer in the transducer probe results in a significant simplification of the overall aberration correction technique for the entire ultrasound diagnostic imaging system.
