  • Patent number: 10908269
    Abstract: Methods of ultrasound imaging, some of which comprise: generating one or more transmit beams, wherein the boresight of each of the transmit beams points to a direction associated with a target region generating one or more receive beams using a probe (26) comprising a transducer array (30); for each receive beam or group of receive beams, sampling the received signal one or more times, wherein each sample is associated with a certain volume within the target region (“volume-gate”), and wherein multiple space-dependent samples are taken over the probe for each volume-gate; and processing the space-dependent samples, said processing comprising: applying beamforming sample alignment such that each space-dependent sample associated with a volume-gate is aligned; for each aligned volume-gate, computing one or more clutter suppression features, wherein a clutter suppression feature is dependent on the signal variability of the space-dependent samples; for each aligned volume-gate, computing a metric value wherein t

  • Patent number: 9451932
    Abstract: A method of ultrasound imaging is provided herein. The method includes the following stages: transmitting ultrasound radiation towards a target and receiving reflections of the ultrasound radiation from a region of the target in a main reflected signal and one or more auxiliary reflected signals, wherein each one of the reflected signals comprises an input dataset and is associated with a beam with a different and distinct beam pattern; compounding the input datasets from the main reflected signal and one or more auxiliary reflected signals, by the use of a compounding function, said compounding function using parameters derived from spatial analysis of the input datasets.

  • Publication number: 20130343627
    Abstract: There is provided a method for reverberation and/or clutter suppression in ultrasonic imaging, comprising: computing similarity measures between voxels within a cine-loop or subset of the cine-loop, to assess their spatial and/or temporal self-similarity; for at least one of: (i) each voxel; (ii) each group of adjacent voxels within the cine-loop or subset of the cine-loop; and (iii) each group of voxels which are determined to be affected by reverberations and/or clutter, based on one or more criteria; computing one or more reverberation and/or clutter parameters; and for at least one of: (i) each voxel; (ii) each group of adjacent voxels within the cine-loop or subset of the cine-loop; and (iii) each group of voxels which are determined to be reverberation and/or clutter affected voxels, based on one or more criteria, applying reverberation and/or clutter suppression using the corresponding reverberation and/or clutter suppression parameters.

  • Patent number: 8045777
    Abstract: A method for ultrasonic imaging includes transmitting ultrasonic radiation toward a target and receiving the ultrasonic radiation reflected from a region of the target. A main reflected signal and an auxiliary reflected signal are defined. The reflected signals have different respective main and auxiliary beam patterns. A difference between the main reflected signal and the auxiliary reflected signal is taken, so as to generate an output signal containing a reduced level of clutter in comparison with the main reflected signal.
