摘要： For measurement point determination in imaging with a medical scanner, the user selects a location on the image. Rather than using that location, an “intended” location corresponding to a local boundary or landmark represented in the image is identified. The medical scanner uses the simple user interface to more exactly determine points for measurement. One or more rays are cast from the user selected location. The actual location is found by examining data along the ray or rays. For 2D imaging, the rays are cast in the plane. For 3D imaging, the ray is cast along a view direction to find the depth. The intensities along the ray or around the ray are used to find the actual location, such as by application of a machine-learnt classifier to the limited region around the ray or by finding intensities along the ray relative to a threshold.

摘要： An ultrasound imager provides for LAA closure guidance. Using ultrasound imaging allows for modeling over time (e.g., throughout a heart cycle). An anatomy model of the LAA over time is used to create a biomechanical model personalized to the patient. The personalized models and a model of one or more closure devices are used to select a closure device for the patient appropriate for the entire heart cycle and to guide placement of the selected closure device during an implantation.

摘要： For cardiac flow detection in echocardiography, by detecting one or more valves, sampling planes or flow regions spaced from the valve and/or based on multiple valves are identified. A confidence of the detection may be used to indicate confidence of calculated quantities and/or to place the sampling planes.

摘要： An entire volume is scanned. A sub-volume is separately scanned with different settings for beamforming parameters, allowing greater image quality for the sub-volume while providing context from the volume. The anatomy of interest is periodically detected, and the sub-volume shifted in position to cover the anatomy of interest, allowing for relatively continuous volume imaging with enhanced quality imaging of the sub-volume. Interleaving by volume and sub-volume slices may allow for optimization of relative frame rate and image quality. Different combinations between volume and sub-volume data for anatomy detection and display may provide for desired imaging while allowing the regular detection of the anatomy.
摘要翻译： 扫描整个卷。 使用不同的波束成形参数设置对子卷进行单独扫描，从而提供子卷的更高图像质量，同时从卷提供上下文。 周期性地检测感兴趣的解剖结构，并且子容积在位置上移动以覆盖感兴趣的解剖结构，从而允许相对连续的体积成像，同时增强子体积的质量成像。 通过卷和子卷切片进行交织可以优化相对帧速率和图像质量。 用于解剖检测和显示的体积和子体积数据之间的不同组合可提供期望的成像，同时允许定期检测解剖结构。

摘要： A regurgitant orifice of a valve is detected. The valve is detected from ultrasound data. An anatomical model of the valve is fit to the ultrasound data. This anatomical model may be used in various ways to assist in valvular assessment. The model may define anatomical locations about which data is sampled for quantification. The model may assist in detection of the regurgitant orifice using both B-mode and color Doppler flow data with visualization without the jet. Segmentation of a regurgitant jet for the orifice may be constrained by the model. Dynamic information may be determined based on the modeling of the valve over time.

摘要： In valve modeling from medical scan data, chordae are modeled as a dense structure. Rather than attempting to provide the same number of chordae (e.g., 25) as found in a human valve, hundreds or thousands of chordae connectors are used. Since solving for lengths of so many chordae may be computationally intensive, the lengths of only a few are solved, and the lengths of the rest of the chordae are derived from the lengths of the few.
