Publication number: 20120165670Abstract: Ultrasound aberration, especially in transcranial imaging or therapy, is corrected by capturing the laterally two-dimensional nature of the aberration in the ultrasound being received, as by means of a two-dimensional receiving transducer array (104, 108). In some embodiments, transmissive ultrasound (164) is applied through the temporal window and is, for example, emitted from one or more real or virtual point sources (160) at a time, each point source being a single transducer element or patch or the geometrical focus of a collection of elements or patches. A patch may serve, in one aspect as a small focused transducer in the near field. A contralateral array (104, 108) is, in one version, comprised of the point sources.Type: ApplicationFiled: August 25, 2010Publication date: June 28, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: William Tao Shi, Francois Guy Gerard Marie Vignon, Jeffry Earl Powers, Brent Stephen Robinson, Michael Richard Burcher, Vijay Shamdasani

Patent number: 6695783Abstract: A digital multiline beamformer is provided which produces multiple receive beams in response to a single transmit event. An embodiment of the present invention includes a bulk delay which provides a common steering delay applicable to all of the beams received at one time. The bulk delay is succeeded by parallel filter processing paths which produce finely focused multiple beams simultaneously. In one embodiment a multiphase filter produces the samples for multiple beams, which is advantageous when the number of simultaneously produced beams is greater than the number of phases produced by the fine focus filter.Type: GrantFiled: December 22, 2000Date of Patent: February 24, 2004Assignee: Koninklijke Philips Electronics N.V.Inventors: Derek Henderson, Brent Stephen Robinson, James Moore, David N. Roundhill, Gary Allen Schwartz

Patent number: 6623432Abstract: An ultrasonic imaging method and apparatus are described for imaging the coronary arteries of the heart. The vascular system is infused with an ultrasonic contrast agent. A volumetric region of the heart wall including a coronary artery is three dimensionally scanned. A projection image of the volumetric region is produced from the scanning, providing a two dimensional contrast image of the coronary artery with the appearance of an angiogram. Preferably the coronary artery signals are segmented from contrast signals emanating from the myocardium and the heart blood pool so that the coronary arteries are clearly highlighted and distinct in the ultrasonic angiogram.Type: GrantFiled: July 17, 2001Date of Patent: September 23, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Jeffry E. Powers, Michalakis Averkiou, Matthew Bruce, Danny M. Skyba, Robert R. Entrekin, John D. Fraser, Clifford R. Cooley, Brent Stephen Robinson, David N.

Patent number: 6582367Abstract: An ultrasonic 2D array has elements extending in two dimensions which can be individually controlled and operated to form a 2D array for scanning a volumetric region in three dimensions. Individual ones of the elements can also be selected and operated together to form a 1D array for scanning a planar region in two dimensions. The array transmits scanlines to scan the volumetric region and the planar region in a time interleaved manner with the frame rate of the planar region be higher than that of the volumetric region. A spectral display may also be produced of a sample volume located in the planar region.Type: GrantFiled: September 15, 2000Date of Patent: June 24, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Andrew L. Robinson, David N. Roundhill, Brent Stephen Robinson, Paul Detmer

Patent number: 6482157Abstract: Multiline acquisition is used to acquire groups of beams in response to transmit pulses. At least some of the beams from spatially adjacent groups are coaxially aligned. The echo information is detected and coaxially aligned beams are blended together using weighting functions which vary as a function of the time and location of the blended beams from their transmit beam apertures to gradually blend the aligned beams together spatially, thereby reducing multiline image artifacts. Echoes from moving objects in coaxially aligned beams may be aligned axially before the beams are blended together.Type: GrantFiled: March 30, 2001Date of Patent: November 19, 2002Assignee: Koninklijke Philips Electronics N.V.Inventor: Brent Stephen Robinson
