20090306503 | ADAPTIVE VOLUME RENDERING FOR ULTRASOUND COLOR FLOW DIAGNOSTIC IMAGING - Adaptive volume rendering is provided for medical diagnostic ultrasound. The opacity of B-mode data is set relative to the opacity of Doppler data. The opacities for the different types of data are set as a function of ray depth. For example, the opacity of B-mode data near a tissue border is set to be more opaque than for tissue away from the border, and the opacity for flow data near a flow border is set to be less opaque than for flow away from the border. An image is rendered using a rendering parameter set as a function of ray depth, B-mode information and Doppler information. Other processes for enhancing and/or using rendering may be used. | 12-10-2009 |
20090306513 | Multi-Plane/Multi-Slice Processing For 2-D Flow Imaging in Medical Diagnostic Ultrasound - A volumetric method for 2-D flow imaging is provided in medical diagnostic ultrasound. Flow data for a volume is acquired. For more rapid acquisition, broad beam transmission and reception along many scan lines distributed in the volume is used. The volumetric flow data is filtered, such as by calculating statistical information, to generate a planar/2-D flow image. The statistical information from the three-dimensional flow data is used to determine the display values for the flow imaging. | 12-10-2009 |
20110208056 | Volumetric Quantification for Ultrasound Diagnostic Imaging - Volumetric quantification is provided in medical diagnostic ultrasound. By acquiring both B-mode and color flow data without stitching or acquiring in real-time at tens of volumes a second, more reliable quantification may be provided. Using multiple regions of interest in a volume may allow for more accurate and/or complete flow information, such as averaging flow from different locations in the same structure (e.g., use preservation of mass to acquire multiple measures of the same flow). | 08-25-2011 |
20110218435 | Prediction-Based Flow Estimation for Ultrasound Diagnostic Imaging - 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. | 09-08-2011 |

20090285089 | Method and Apparatus for Validating Control and Data Plane Association - A method and apparatus for validating control and data plane association is described. In one embodiment of the invention, a first provider edge (PE) network element negotiates a pseudowire with a second PE network element. The pseudowire is uniquely identifiable between the first and second PE network element with a unique pseudowire identifier. The first PE network element receives OAM (operations, administration, and management) packets each including a pseudowire identifier from the second PE network element over the negotiated pseudowire. If an OAM packet is received with a pseudowire identifier that does not match the negotiated pseudowire, the first PE network element determines a data plane fault is associated with the pseudowire on the second PE network element. However, if the OAM packets include the pseudowire identifier that matches the negotiated pseudowire, the control and data plane association of the second PE network element is validated. Other methods and apparatuses are also described. | 11-19-2009 |
20090296727 | Method and Apparatus to Count MAC Moves at Line Rate - A method and apparatus for counting Media Access Control (MAC) address moves at line rate is described. According to one embodiment of the invention, a line card in a network bridge receives a frame at a port having a source MAC address that is associated with a different port of the network bridge. The line card signals a control card of the network bridge that the source MAC address has moved. The control card processes the source MAC address move and increments a MAC address move counter. If the MAC address move counter exceeds a MAC address move count threshold for a given time interval, the control card signals each line card in the network bridge to count each frame they receive on any port having that source MAC address. Other methods and apparatuses are also described. | 12-03-2009 |
20090296728 | Method and Apparatus for Prioritizing Source MAC Address Miss Processing - A method and apparatus for prioritizing source Media Access Control (MAC) address miss processing is described. In one embodiment of the invention, a network bridge receives multiple frames (each including a source MAC address) at multiple ports of multiple line cards. If a source MAC address of a received frame is associated with a different port than which it was received on, the network bridge places a source MAC miss message in a high priority MAC move miss queue. If a source MAC address of a received frame is not associated with any of the ports of the network bridge, the network bridge places a source MAC miss message in a low priority unknown MAC miss queue. The network bridge processes those source MAC miss messages in the high priority queue with a higher priority than processing those source MAC miss messages in the low priority queue. | 12-03-2009 |
