  • Patent number: 11497477
    Abstract: Periodic displacement occurs in body tissue due to heartbeat. A peak level D of the movement distance of the body tissue is detected (Step 21), and a heartbeat cycle T is calculated from a frequency spectrum (Steps 22 and 23). By dividing twice the peak level D by the heartbeat cycle T, the moving velocity of the body tissue in a unit heartbeat cycle is calculated (Step 24). By dividing the moving velocity by a frame rate r, an average movement distance of the body tissue between frames is calculated (Step 25). In a case where the average movement distance is smaller than a predetermined threshold value, a time interval between the frames used for the calculation of the movement distance is extended (being Step 26 NO, Step 27).

  • Patent number: 11432804
    Abstract: The invention provides methods and systems for generating an ultrasound image. In a method, the generation of an ultrasound image comprises: obtaining channel data, the channel data defining a set of imaged points; for each imaged point: isolating the channel data; performing a spectral estimation on the isolated channel data; and selectively attenuating the spectral estimation channel data, thereby generating filtered channel data; and summing the filtered channel data, thereby forming a filtered ultrasound image. In some examples, the method comprises aperture extrapolation. The aperture extrapolation improves the lateral resolution of the ultrasound image. In other examples, the method comprises transmit extrapolation. The transmit extrapolation improves the contrast of the image. In addition, the transmit extrapolation improves the frame rate and reduces the motion artifacts in the ultrasound image. In further examples, the aperture and transmit extrapolations may be combined.

  • Patent number: 11366208
    Abstract: In some embodiments, ultrasound receive beamforming yields beamformed samples, based upon which spatially intermediate pixels (232, 242, 244) are dynamically reconstructed. The samples have been correspondingly derived from acquisition through respectively different acoustic windows (218, 220). The reconstructing is further based on temporal weighting of the samples. In some embodiments, the sampling is via synchronized ultrasound phased-array data acquisition from a pair of side-by-side, spaced apart (211) acoustic windows respectively facing opposite sides of a central region (244) to be imaged. In particular, the pair is used interleavingly to dynamically scan jointly in a single lateral direction in imaging the region. The acquisition in the scan is, along a synchronization line (222) extending laterally across the region, monotonically progressive in that direction. Rotational scans respectively from the window pair are synchronizable into a composite scan of a moving object.

  • Patent number: 11249188
    Abstract: Systems and methods for filtering an analog waveform before it is sampled by an analog-to-digital converter (ADC) in an ultrasound system are provided. The waveform can be filtered by delaying the same waveform by two different time delays and combining the delayed waveforms to effectively cancel out the fundamental components, thereby providing more sensitive detection of harmonic components in received echo signals. This filtering approach leverages an architecture that can also be used for multiline beamforming to perform the temporal filtering, in which a single acoustic signal can be read out of the ARAM twice, separated by time, taking advantage of the fact that the ARAM allows for non-destructive read operations.

  • Patent number: 11220262
    Abstract: An autonomous driving system mounted on a vehicle determines a target path based on necessary information and performs vehicle travel control such that the vehicle follows the target path. A first coordinate system is a vehicle coordinate system at a first timing when the necessary information is acquired. A second coordinate system is a vehicle coordinate system at a second timing later than the first timing. The autonomous driving system calculates, based on the necessary information acquired at the first timing, a first target path defined in the first coordinate system. Then, the autonomous driving system corrects the first target path to a second target path defined in the second coordinate system by performing coordinate transformation from the first coordinate system to the second coordinate system. The autonomous driving system uses the second target path as the target path to perform the vehicle travel control.
