  • Patent number: 11717256
    Abstract: Motion independent acoustic radiation force impulse imaging is provided. Rather than rely on the displacement over time for each location, the displacements over locations for each time are used. Parallel beamforming is used to simultaneously sample across a region of interest. Since it may be assumed that the different locations are subjected to the same motion at the same time, finding a peak displacement over locations for each given time provides peak or profile information independent of the motion. The velocity or other viscoelastic parameter may be estimated from the displacements over locations.

  • Patent number: 11650300
    Abstract: An ultrasound system according to the present disclosure may include a beamformer configured to perform per-channel weighting on the RF signals received at each channel in order to reduce noise clutter in the image. For this purpose, the beamformer may receive at one or more channels associated with an active aperture, sets of receive signals associated with respective transmit beams that at least partially overlap. The beamformer may alter the receive space, e.g., to align the sets of receive signals to a common location (e.g., between the transmit beams) and generate a coherence-based weighting value that may be indicative of blockage. The coherence-based weighting value may be applied on a per-channel basis to the receive signals. The beamformer may also communicate the coherence metric to the controller for altering the transmit space.

  • Patent number: 11628012
    Abstract: First and second skeleton model data is determined based on first and second surface data of a patient. Each of the skeleton model data describes geometries of rigid anatomic structures of a patient at a different point in time. Skeleton difference data is determined describing differences between the geometries of the rigid anatomic structures. In a next step, movement instruction data is determined which describes movement to be performed by the rigid anatomic structures to minimize the differences, i.e. to correct the posture of the patient. The movement instruction data is for example determined based on anatomy constraint data which describes anatomical movement constraints for the rigid anatomic structures (e.g. range of motion of a joint). An instruction is displayed (e.g. using augmented reality), guiding the user how to move the rigid anatomic structures so as to correct the patients posture.
