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.
摘要翻译：用超声波确定流量信息（例如，速度和加速度）和/或压力梯度信息。同时使用模型和最小二乘法分析速度和加速度。可以使用模型和最小二乘法分析来提供速度信息的抗锯齿。压力梯度由速度信息自动计算，更可能提供一致的测量。通过将感兴趣区域自动定位在多维空间图像或空间 - 时间图像中，可以进一步增加一致性。产生图像内每个空间位置的压力梯度的参数图像以及三角洲压力曲线。可以使用上述特征中的任何一个或两个或更多个特征的组合。

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.

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.
