US Patent:

6432056, Aug 13, 2002

Filed:

Oct 8, 1999

Appl. No.:

09/415958

Inventors:

Clifford R. Cooley - Seattle WA
Thomas J Sabourin - Mill Creek WA
Brent Stephen Robinson - Kirkland WA

Assignee:

ATL Ultrasound - Bothell WA

International Classification:

A61B 800

US Classification:

600443, 600447

Abstract:

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.

Appl. No.:

09/912094

Clifford R. Cooley - Seattle WA
Brent Stephen Robinson - Kirkland WA

Assignee:

Koninklijke Philips Electronics N.V. - Eindhoven

International Classification:

A61B 800

US Classification:

600443, 600442, 128916

Abstract:

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.

Appl. No.:

10/570193

Inventors:

James Jago - Seattle WA, US
Brent Robinson - Kirkland WA, US

Assignee:

Koninklijke Philips Electronics, N.V.

International Classification:

A61B 8/00

US Classification:

600447

Abstract:

An ultrasonic diagnostic imaging system and method are described in which spatially compounded images are produced by transmitting ultrasound beams in different directions during a common transmit-receive interval. Echoes are received from the different beam directions and are beamformed by a multiline beamformer to produce differently steered beams of coherent echo signals. The echoes are combined on a spatial basis with echoes from different look directions which correspond to the same spatial location being combined. The resulting spatially compounded image is displayed.

International Classification:

A61B 8/00

US Classification:

600437, 600447, 600463

Abstract:

An ultrasonic diagnostic imaging system produces an image with an extended focal range by transmitting a plurality of beams spaced along an array for multiline reception. The receive multilines of a plurality of transmit beams are spatially aligned and are combined with phase adjustment between the respective receive multilines to prevent undesired phase cancellation. The combined multilines produce the effect of an extended transmit focus so that an image produced using the combined multilines exhibits an extended focal range. To prevent motion artifacts the multiline order is adjustable as a function of image motion.
