  • Patent number: 10641879
    Abstract: The present disclosure relates to an ultrasound multi line dynamic receive focusing beam former that is part of an ultrasound system, where the beam former of the present invention resolves conceptually the, in the prior art dynamic receive focusing beam formers, by fundament, internally generated distortions, which (in the prior art), become internally generated by the beam former process itself. These distortions within prior art beam formers, typically compromises, to some degree, the ability of accurate detections after the dynamic receive focusing beamforming. The present invention advantage is an ultrasound system capable of very accurate focusing selectivity with a high dynamic range, and very low signal distortion, therefore capable of, for example, a clear detection of harmonics and super harmonics, due to the fundamentally absence of internal distortion-generation.

  • Patent number: 10444333
    Abstract: Methods and systems are provided that perform baseband beamforming of ultrasound signals. The methods and systems obtain receive signals from transducers of an ultrasound probe and demodulate the receive signals to obtain complex receive signals having in-phase (I) and quadrature (Q) components. The methods and systems apply time delay and phase correction to the complex receive signals to form delayed complex receive signals before summing the delayed complex receive signals to produce a coherent receive signal. The phase correction includes applying coarse and fine corrections where the coarse correction is calculated as a multiple of a sampling time and the fine correction is calculated as a fraction of the sampling time. The methods and systems apply the coarse and fine corrections contemporaneously by multiplying the complex receive signal by a complex carrier delayed by a multiple of the sampling time and delayed by the fraction of the sampling time.

  • Patent number: 10152799
    Abstract: Provided is a method and arrangement for registering first image data of a first stream with second image data of a second stream. The image data include image information about at least one organ, wherein a shape and/or position of the organ is cyclically changing: Each of the streams include a series of images of the at least one organ at a plurality of different discrete stages of the cyclic change so that each image corresponds to one of the discrete stages. A phase variable defines the stage of the cyclic change and a phase value of the phase variable is assigned to each image within each stream, thereby defining the discrete stage represented by the image. A registration is determined for a pair of images selected by choosing or interpolating images from the first stream and second stream to which a same phase value is assigned.
