A display processor for an ultrasonic imaging system includes a two-dimensional filter to generate a smoothed image signal I.sub.p from a high spatial resolution image signal I.sub.D. I.sub.p is optimized for high contrast resolution and good tissue differentiation, and I.sub.D is optimized for high ...

Kutay Ustuner, Anming He: Ultrasonic imaging system and method with SNR adaptive processing. Acuson Corporation, Brinks Hofer Gilson & Lione, July 23, 2002: US06423003 (12 worldwide citation)

An ultrasonic imaging system includes a processor that varies the receive signal path parameters as a function of the signal to noise ratio of the echo signal. Background noise information is either acquired by imaging with the transmitters turned off, or estimated by using the known differences in ...

Anming He, Kutay Ustuner: Noise estimation method and apparatus for noise adaptive ultrasonic image processing. Acuson Corporation, March 9, 2004: US06704437 (7 worldwide citation)

A noise-adaptive method for processing an ultrasonic image set forms a filtered image set having a selectively enhanced noise component as compared to the original image set. A noise parameter is generated as a function of the image set and the filtered image set, and then the noise parameter is use ...

Kutay Ustuner: Ultrasound displacement imaging with spatial compounding. Siemens Corporation, August 13, 2009: US20090203997-A1

Artifacts in ultrasound displacement images are reduced by combining multiple component displacement images. For each component displacement image first a pre-displacement ultrasound image is generated from a particular imaging angle. Then a displacement force is applied on the object at a desired d ...
