  • Patent number: 6716168
    Abstract: A method and system for both enhancing drug uptake by application of therapeutic transmissions of acoustic energy and imaging a region for applied therapy with a same transducer and ultrasound system. An ultrasonic image of a field of view is generated while localized delivery of a drug is enhanced with ultrasound energy. Using the same transducer and ultrasound system reduces costs and increases system availability for a broader range of medical practitioners. For example, a single linear array of transducer elements is used for application of both imaging and therapeutic ultrasound. As another example, a transmitter is provided that transmits therapeutic transmissions having substantially equal positive and negative peaks at the face of the transducer and also is operable to transmit imaging acoustic energy. As yet another example, therapeutic pulses of acoustic energy are transmitted to have greater power for heating than imaging, but a mechanical index or pressure comparable to imaging transmissions.

  • Patent number: 5782766
    Abstract: An image registration based method and a corresponding apparatus are provided for creating composite, panoramic images, in which consecutive ultrasonic image frames are correlated in order to derive transducer motion information. The individual images can be divided into several smaller sub-image regions and a fast and robust image motion detection algorithm is used to measure the sub-image motion and then to determine an initial estimation of the local motion vectors. The initial estimation is combined with two measurement parameters by use of a fuzzy logic technique to derive a final estimation of the local motion vectors. The final local motion vectors are then used to estimate global image motion. Compound images are then diplayed based on the derived global image motion. The speed of motion of the transducer is also estimated and a "speedometer" is displayed to help the user move the transducer within efficient speed ranges.

  • Patent number: 5566675
    Abstract: An ultrasonic imaging system is provided that effectively corrects for inhomogeneities in the imaged media. The ultrasonic imaging system comprises a transducer array having a plurality of transducer elements each being separately operable to provide an ultrasonic pulse in response to a driving signal and to provide a corresponding echo signal in response to a received echo based on the ultrasonic pulse. A transmitter is coupled to the transducer array and provides the driving signal to each respective one of the transducer elements. The driving signals define a steered beam of the transducer array. A receiver is coupled to the transducer array and receives the echo signal from each respective one of the transducer elements. The receiver includes a beamformer section that produces a single matched and summed signal from the echo signals of the plurality of transducer elements. The beamformer section comprises a plurality of processing modules coupled in a cascading arrangement with separate processing stages.
