  • ULTRASOUND ACQUISITION
    Publication number: 20130211254
    Abstract: Ultrasound acquisition Information about a structure (701) within a body is acquired by providing data defining a non-straight line (42b), at least a part of which corresponds to the structure (701); transmitting an ultrasound transmit signal (44b) into the body; receiving reflections (400-402) of the transmit signal (44b); processing the received reflections (400-402) so as to trace the focal point (403-405) of a receive beam along the path of the non-straight line (42b); using reflections (400-402) of the transmit signal (44b) from along the non-straight line (42a) to acquire information about the structure (701).

  • Reduction of multiline artifacts in doppler imaging
    Patent number: 8475380
    Abstract: Certain embodiments of the present technology provide systems and methods that provide reduction of multiline artifacts in Doppler imaging. Certain embodiments provide for various ensembles of transmit beams at different spatial locations and overlapping receive beams between the locations. Certain embodiments provide for calculating various auto-correlation estimates based on the received beams and then combining the auto-correlation estimates to create an image. In certain embodiments, combining the auto-correlation estimates comprises applying a linear interpolation filter that decreases the weight applied for receive beams that are spatially located further away from the transmit beam.
