摘要： The success of the positioning of devices for deployment inside an aneurysm, for example, is reliant on processes,which take place within an intervention procedure. For example, the position, orientation, or trajectory of the intervention device can affect the final position of a device for deployment deployed on the intervention device. Therefore, it is useful to predict the deployment position of a device for deployment based on a current localization of only the intervention device within an object of interest.

摘要： :An ultrasound system includes a processor circuit in communication with an array of acoustic elements and a display. The processor circuit receives B-mode and/or Doppler ultrasound data representative of mitral regurgitation associated with an orifice in a mitral valve. The processor circuit generates a model of the orifice and outputs a graphical representation of the model of the orifice to the display. The processor circuit generates a blood flow model of the mitral regurgitation based on the model of the orifice. The processor circuit compares the blood flow model to the Doppler data. The processor circuit changes the model of the orifice (e.g., a different shape, a different position, and/or a different orientation) such that the blood flow model is changed to match the Doppler data. The processor circuit outputs a graphical representation of the orifice with the different shape, the different position, and/or the different orientation to the display.

摘要： The invention provides a method for assessing cardiac valve regurgitation. The method includes obtaining 4D ultrasound data of a region of interest, wherein the region of interest comprises a cardiac valve. The 4D ultrasound data comprises a time sequence of 3D ultrasound images comprising B-mode ultrasound data and color Doppler ultrasound data. Image stabilization is performed on the images of the time sequence of 3D ultrasound images and a dynamic jet is then segmented from the time sequence of stabilized 3D ultrasound images. A dynamic surface model is fit to the valve in the time sequence of stabilized 3D ultrasound images based on the segmented jet. The method further includes identifying a dynamic regurgitant orifice based on the applied surface model and the time sequence of stabilized 3D ultrasound images and fitting a flow convergence model to the time sequence of stabilized 3D ultrasound images based on the identified dynamic regurgitant orifice. A regurgitant flow is then estimated based on the identified regurgitant orifice.

摘要： The invention provides a color Doppler ultrasound imaging method. The method includes acquiring a plurality of sparse color Doppler ultrasound image frames and B-mode ultrasound image frames. The color Doppler and B-mode image frames are then pre- processed before estimating a vector flow based on said frames by means of solving a flow vector field in a whole field of view of the image frames through an optimization framework, in which a mask is adapted to define a sparse area of observed color Doppler measurements within the sparse color Doppler image frames. A new color Doppler image frame is generated based on this estimate and included in the output image.

摘要： An ultrasound imaging system may automatically find and track a coronary artery in a 3D volume. The artery location may be considered fixed within each of the overlapping spans of time data used for spectral processing in some examples. Data from along the artery within the 3D volume may be coherently integrated, and average beam-to-flow angle may be compensated for automatically. Optionally, a live, 3D rendered graphic or color flow image of the 3D volume may be displayed while the spectrogram is displayed. Optionally, audio output reflecting the spectral data may be provided to a speaker.

摘要： The invention provides a method for generating a transvalvular pressure quantification within a cavity. The method includes acquiring a plurality of color Doppler ultrasound image frames, wherein the image frames comprise a view of a valve, one of which is then presented to a user. The user may then provide an input to indicate the location of the valve within the image frame. The location of the valve is then tracked within the remaining image frames based on the user input. A vector flow is estimated based on the color Doppler image frames and the tracked location of the valve, which may be used to estimate the flow across the valve(s) and in the cavity.
