Patent Number Title Of Patent Date Issued
6160340 Multifrequency ultrasonic transducer for 1.5D imaging December 12, 2000
An ultrasonic transducer has a center row of transducers operating at a center row frequency and first and second outer rows of transducers operating at a common frequency or different frequencies lower than the center row frequency. In an enhancement of the ultrasonic transducer arr
5718230 Method and apparatus for creating ultrasound images using a reduced number of transmit beam line February 17, 1998
An ultrasound system creates ultrasound images at faster frame rate by eliminating ultrasonic transmissions along every beam line. Preferably, ultrasound images are created by alternately transmitting ultrasonic signals on the even and odd transmit beam lines. Parallel beam forming is
5632277 Ultrasound imaging system employing phase inversion subtraction to enhance the image May 27, 1997
A method for generating an ultrasound image that enhances regions occupied by non linear scattering media. The method utilizes first and second ultrasound pulses that are alternatively transmitted into the specimen being imaged. The first and second ultrasound pulses are amplitude mo
