  • Patent number: 11969286
    Abstract: A system for visualization and quantification of ultrasound imaging data according to embodiments of the present disclosure may include a display unit, and a processor communicatively coupled to the display unit and to an ultrasound imaging apparatus for generating an image from ultrasound data representative of a bodily structure and fluid flowing within the bodily structure. The processor may be configured to estimate axial and lateral velocity components of the fluid flowing within the bodily structure, determine a plurality of flow directions within the image based on the axial and lateral velocity components, differentially encode the flow directions based on flow direction angle to generate a flow direction map, and cause the display unit to concurrently display the image including the bodily structure overlaid with the flow direction map.

  • Patent number: 11965959
    Abstract: The present disclosure describes ultrasound systems configured to enhance flow imaging and analysis by adaptively adjusting one or more imaging parameters in response to acquired flow measurements. Example systems can include an ultrasound transducer and one or more processors. Using the system components, mean flow velocity magnitude and acceleration can be determined within a target region during an acquisition phase, which may include a cardiac cycle. One or more adjusted flow imaging parameters, such as adjusted ensemble length, temporal smoothing filter length and/or step size, can be determined based on the acquired flow measurements to increase the signal quality of newly acquired ultrasound echo signals. The adjusted flow imaging parameters can then be applied by the ultrasound transducer during a second acquisition phase.

  • Patent number: 11950959
    Abstract: The present disclosure describes ultrasound imaging systems and methods for ultrasonically inspecting biological tissue. An ultrasound imaging system according to the present disclosure may be configured to automatically apply tissue-specific imaging parameter settings (312, 314) based upon the automatic identification of the type of tissue being scanned. Tissue type identification (315) may be performed automatically for the images in the live image stream (304) and thus adjustments to the imaging settings may be applied automatically by using a neural network (320) and thus dynamically during the exam obviating the need for the sonographer to manually switch presets or adjust the imaging settings when moving to different portion of the anatomy.

  • Publication number: 20050119167
    Abstract: The present invention relates to a process for the preparation of cyclic peptides, in particular the preparation of Ac-Phe[Orn-Pro-D-Cha-Trp-Arg] known as 3D53 or PMX53 which is a macrocyclic peptidomimetic of the human plasma protein C5a and displays excellent anti-inflammatory activity.
