  • Patent number: 11571186
    Abstract: An ultrasound imaging system includes a processor programmed to identify the type of tissue being imaged and to confirm that one or more system settings and/or the energy of ultrasound imaging signals delivered is set appropriately for such tissue. In one embodiment, an image obtained with the ultrasound imaging system is analyzed to determine if the tissue is ophthalmic (eye) tissue. If so, the system parameter settings and/or the transmit power of the signals produced by the ultrasound system are adjusted or maintained at a level that is appropriate for imaging such tissue.
    Type: Grant

  • Patent number: 10713758
    Abstract: The present technology is generally directed to filtering systems and methods for suppression of reverberation artifacts in ultrasound images. In some embodiments, a method of obtaining a filtered ultrasound image includes taking a first ultrasound image of a target tissue using an applicator. At least a portion of the applicator is moved such that the reverberation artifact ultrasound path length changes relative to the first position of the applicator. A second ultrasound image of the target tissue is then taken. The first and second ultrasound images are synthesized using at least one filtering method. The filtering method attenuates or removes reverberation artifacts in the synthesized ultrasound image.

  • Publication number: 20110245659
    Abstract: Systems and methods which facilitate the correct placement of an instrument internal to an object aided by an overlay superimposed on an image are disclosed. Exemplary embodiments facilitate placement of a needle tip within a patient's body using on overlay superimposed on a sonographic image. A superimposed overlay of embodiments is created by monitoring a fixed point of an external portion of the instrument in relation to an imaging transducer. Superimposed overlays provided according to embodiments provide one or more graphical target designator and one or more graphical instrument designator which, when controlled to be disposed in a predetermined position, indicate proper placement of the instrument.

  • Patent number: 5477858
    Abstract: An ultrasound imaging system is provided which produces gray scale images of the anatomy simultaneous with Doppler signal processing so as to provide a single real-time image that shows not only the vascular anatomy and surrounding tissue but also flow events in the vascular compartment. A phased linear array having near-continuous focus over the scanning field provides high resolution and very small Doppler sample volumes. The system tests incoming signals from throughout the scanning field for amplitude, phase and frequency so as to determine B-mode data, motion presence and direction, and echo source velocity.
