  • Publication number: 20240153048
    Abstract: Methods and systems are provided for removing visual artifacts from a medical image acquired during a scan of an object, such as a patient. In one example, a method for an image processing system comprises receiving a medical image; performing a wavelet decomposition on image data of the medical image; performing one or more 2-D Fourier transforms on wavelet coefficients resulting from the wavelet decomposition; removing image artifacts from the Fourier coefficients determined from the 2-D Fourier transforms using a filter; reconstructing the medical image using the filtered Fourier coefficients; and displaying the reconstructed medical image on a display device of the image processing system.

  • Patent number: 11521335
    Abstract: The disclosure provides for a method for generating an ultrasound image that includes transmitting, by a plurality of transmitters in a transducer, at least two transmit beams at different angles, where at least parts of the transmit beams cover an overlapping region, and receiving, by a plurality of sensors of the transducer, reflected signals of the transmit beams. The method further comprises calculating channel coherence for the received signals to produce one or more channel coherence images, and calculating transmit coherence for the received signals to produce one or more transmit coherence images. The information from at least one of the channel coherence images and at least one of the transmit coherence images are combined to identify moving objects. The received signals from different transmits in overlapping regions are then processed to produce a final image that is compensated for the moving objects.

  • Patent number: 11488298
    Abstract: Methods and systems are provided for improving image quality of ultrasound images by automatically determining one or more image quality parameters via a plurality of separate image quality models. In one example, a method for an ultrasound system includes determining a plurality of image quality parameters of an ultrasound image acquired with the ultrasound system, each image quality parameter determined based on output from a separate image quality model, and outputting feedback to a user of the ultrasound system based on the plurality of image quality parameters.

  • Patent number: 11308609
    Abstract: Methods and systems are provided for sequentially selecting scan parameter values for ultrasound imaging. In one example, a method includes selecting a first parameter value for the a first scan parameter based on an image quality of each ultrasound image of a first plurality of ultrasound images of an anatomical region, each ultrasound image of the first plurality of ultrasound images having a different parameter value for the first scan parameter, selecting a second parameter value for a second scan parameter based on an image quality of each ultrasound image of a second plurality of ultrasound images of the anatomical region, each ultrasound image of the second plurality of ultrasound images having a different parameter value for the second scan parameter, and applying the first parameter value for the first scan parameter and the second parameter value for the second scan parameter to one or more additional ultrasound images.

  • Publication number: 20210169455
    Abstract: Methods and systems are provided for improving image quality of ultrasound images by jointly selecting optimal scan parameter values. In one example, a method includes acquiring a plurality of ultrasound images of an anatomical region, each ultrasound image acquired at a different combination of parameter values for a first scan parameter and a second scan parameter, selecting a first parameter value for the first scan parameter and a second parameter value for the second scan parameter based on an image quality of each image, and acquiring one or more additional ultrasound images at the first parameter value and the second parameter value.
