摘要: Flow estimation is provided. The flow is predicted. A mathematical, logic, machine learning or other model is used to predict flow. For example, the boundary conditions associated with a previous flow, the previous flow, and current boundary conditions are used to predict the current flow. The current flow is corrected using the predicted flow. Velocities may be unaliased based on the predicted flow. The predicted flow may replace the current flow. Prediction may additionally or alternatively be used in determination of lateral or elevational flow.

摘要: Three-dimensional cardiac border is delineated in medical imaging. A view is labeled, such as identifying a two-dimensional view as an apical four-chamber view. A three-dimensional border is detected as a function of the view label. For example, the view is associated from a plane through a volume and a known orientation relative to the heart. Labeling the view indicates the orientation of the heart in the scanned volume. By determining the orientation of the heart, border detection processes may be simplified or assisted.

摘要: Flow information (e.g., velocity and acceleration) and/or pressure gradient information are determined with ultrasound. Both velocity and acceleration are simultaneously estimated using a model and least squares analysis. Anti-aliasing of velocity information may be provided using the model and least squares analysis. Pressure gradient is calculated from velocity information automatically, more likely providing consistent measurements. Consistency may be increased further by automatically positioning a region of interest in either a multidimensional spatial image or a spatial-temporal image. A parametric image of pressure gradient for each spatial location within the image is generated as well as a delta pressure curve. Any single one or combinations of two or more of the features described above may be used.

摘要: Parametric imaging of a surface is provided on a medical diagnostic ultrasound imaging system. A bull's eye or Beutel surface representing the scanned tissue, such as a portion of the heart, is formed from planar views, such as apical 4 chamber, apical 2 chamber and long axis views of the heart. Dynamic clips or videos of the parametric imaging provide temporally useful information to a user. The parametric imaging may include information determined from data at different locations or different times, such as strain, velocity, tissue displacement, velocity, or wall thickness. The ultrasound data may be responsive to contrast agents. The ultrasound data may be acquired with a three-dimensional scan.
