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: 6432056Abstract: An ultrasonic diagnostic imaging system is provided which produces scanlines with synthesized transmit foci at a high frame rate of display. Beams are transmitted and received which have different beam steering and focal characteristics. At least one of the received beams is weighted and the steering and focal characteristics of the weighted received beams are interpolated to form scanlines for display which exhibit the focal properties of both beams.Type: GrantFiled: October 8, 1999Date of Patent: August 13, 2002Assignee: ATL UltrasoundInventors: Clifford R.

Patent number: 6315723Abstract: An ultrasonic diagnostic imaging system is provided with synthesized transmit focus. Several beams are transmitted, each with a different transmit focus. Echoes received from the differently focused beams are combined to form a scanline with an extended focus. The echoes are preferably weighted and/or phase adjusted prior to being combined. Combining is performed in the r.f. domain before nonlinear processing of the signals such as amplitude detection. The resultant extended focus scanline exhibits the property of dynamic transmit focusing.Type: GrantFiled: October 8, 1999Date of Patent: November 13, 2001Assignee: ATL UltrasoundInventors: Brent Stephen Robinson, Thomas J Sabourin, Clifford R.

Patent number: 5940123Abstract: A method and apparatus are provided for interpolating image lines from ultrasonically obtained scanlines of an image region. The interpolated lines are preferably formed one-quarter and three-quarters of the distance between each pair of received scanlines by combining weighted samples of the adjacent scanlines in proportion to their distances from the interpolated lines. The received scanlines are preferably formed by a beamformer which samples the received lines at quadrature phases of the scanhead center frequency and filters the samples by combining successive samples of a related phase. The image lines are scan converted by computing a grid of weighted values between each pair of image lines, and using the closest value for each pixel in the ultrasound image.Type: GrantFiled: February 13, 1997Date of Patent: August 17, 1999Assignee: ATL UltrasoundInventors: Ronald E. Daigle, Brent Stephen Robinson, Clifford R. Cooley

Patent number: 5617863Abstract: A technique for scanning an image field with adjacent beams of ultrasonic energy is provided in which initially transmitted beams are transmitted along beam directions at the lateral sides of the image field. Subsequent beams are alternately transmitted on either side of the initially transmitted beams and at lateral locations which converge toward the center of the image field until the full image field has been scanned. In an alternate embodiment initially transmitted beams are transmitted on one side of the center of the image field, subsequent beams diverge from the locations of the initially transmitted beams, and concluding beams laterally converge at a location on the other side of the center of the image field.Type: GrantFiled: June 12, 1995Date of Patent: April 8, 1997Assignee: Advanced Technology Laboratories, Inc.Inventors: David N. Roundhill, Mikhail Starosta, David Rust, Clifford R. Cooley

Patent number: 5390674Abstract: An ultrasonic diagnostic imaging system is provided which scans an image region to receive a plurality of spatially arranged lines of ultrasonic image information signals. These ultrasonic line information signals are used in an interpolater to interpolate one or more lines which are spatially interlineated between each pair of spatially adjoining received lines. These interpolated lines are produced using either the received RF or demodulated IF ultrasonic image information signals. The interpolated lines are produced prior to scan conversion, and preferably prior to nonlinear processing such as detection or log compression to reduce spatial aliasing artifacts. In one preferred embodiment the interpolater comprises a transversal filter of four taps which is responsive to received line information signals from a common range or depth.Type: GrantFiled: December 30, 1993Date of Patent: February 21, 1995Assignee: Advanced Technology Laboratories, Inc.Inventors: Brent S.

Patent number: 5099847Abstract: A technique for increasing the display frame rate of a medical ultrasound imaging system. The system receives trigger signals, each based upon the occurrence of a predetermined event in a subject's cardiac cycle, such as an R-wave. In one technique, in response to each trigger signal, the ultrasound system acquires a series of frames, each frame comprising data representing an image of a portion of the subject's body at an associated acquisition time. A frame time is determined for each frame, each frame time being the time from the preceding trigger signal to the acquisition time for the frame. Two or more frame series are then played back in order of increasing frame times, thereby producing a display frame rate higher than the acquisition frame rate.Type: GrantFiled: November 13, 1989Date of Patent: March 31, 1992Assignee: Advanced Technology Laboratories, Inc.Inventors: Jeffry E. Powers, Ronald E. Daigle, Clifford R. Cooley
