System And Method For Ultrasound Pulse Shaping And Output Power Adjustment Using Multiple Drive Pulses

US Patent:
2006029, Dec 28, 2006
Filed:
Aug 18, 2004
Appl. No.:
10/569252
Inventors:
David Clark - BRIARCLIFF MANOR NY, US
David Sherrill - Westford MA, US
International Classification:
A61B 8/00
US Classification:
600437000
Abstract:
The present invention provides a system and method for ultrasound pulse shaping and output power adjustment using multiple drive pulses. The multiple drive pulses are width modulated to provide the required output signal power and wave-shape characteristics. Using multiple width-modulated pulses provides control over power output that is capable of being varied much more rapidly than using a conventional voltage modulated drive pulse. Additionally, the multiple drive pulses provide better control over unwanted harmonics than does a single drive pulse. These two advantages allow multiple width modulated pulses to increase the capabilities in ultrasonic imaging devices, thereby, allowing for rapid switching between imaging techniques having widely disparate power requirements so that composite diagnostic images may be constructed combining the diagnostic benefits the various imaging techniques have to offer.

Method And Apparatus For 3D Ultrasound Imaging Using A Stationary Beam To Estimate A Parameter

US Patent:
2010016, Jul 1, 2010
Filed:
Jun 15, 2006
Appl. No.:
11/993541
Inventors:
David S. Sherrill - Westford MA, US
Assignee:
KONINKLIJKE PHILIPS ELECTRONICS, N.V. - EINDHOVEN
International Classification:
A61B 8/14
US Classification:
600440, 600443
Abstract:
A method of three-dimensional (3D) ultrasound imaging comprises acquiring ultrasound data representative of an imaging volume as a function of time, from which can be obtained a plurality of two-dimensional images, and acquiring data from a stationary ultrasound beam concurrently with the acquiring of the ultrasound data representative of the imaging volume. The stationary ultrasound beam data is analyzed to derive a parameter from the stationary ultrasound beam data. The method further includes rearranging a plurality of 2D ultrasound images obtained from the acquired ultrasound data for 3D processing as a function of the derived parameter. In one embodiment, acquiring data from the stationary ultrasound beam comprises one or more of an M-mode acquisition, a Doppler mode acquisition, or an acquisition tailored to a specific ultrasound imaging application.
