摘要： An ultrasound imaging system includes a transducer array (202) with a plurality of transducer elements (206) configured to transmit a pulsed field beam into a scan field of view, receive echo signals produced in response to the pulsed field interacting with particles/ structure flowing/moving in the scan field of view, and generate electrical signals indicative of the echo signals. The ultrasound imaging system further includes a beamformer (212) including multiple synthetic transmit aperture beamformers configured to process the electrical signals over a plurality of processing channels (312) into corresponding receive-beams of RF-data with a beam- level delay, channel-level delays, a beam-level gain and channel- level gains. The ultrasound imaging system further includes a velocity processor (216) configured to estimate a flow velocity of the structure flowing in the scan field of view from the RF-data. The ultrasound imaging system further includes a rendering engine (224) configured to display the flow velocity estimate on a display (226) with color- coding.

摘要： A system (800) includes an acquisition engine (837) that acquires ultrasound data for two or more modes with a first acquisition algorithm, including an image mode and a special mode. A rendering engine (834) employs a first rendering algorithm and displays the image in a main display window (902) and the special mode ultrasound data in a viewport (906) superimposed over the main display window. The acquisition engine acquires ultrasound data for the special mode using a second acquisition algorithm and the rendering engine displays a first portion of the generated special mode ultrasound data over the main display window and a second portion of the generated special mode ultrasound data over the viewport using a second rendering algorithm in response to the system receiving an input signal indicative of a movement of the viewport from a first location of the main display window to a second different position of the main display window.

摘要： An ultrasound imaging system (100) includes a velocity processor (118) that processes ultrasound data representing structure flowing through a tubular object and generates vector flow imaging information indicative of the structure flowing through a tubular object based thereon. The vector flow imaging information includes an axial velocity component signal and a lateral component signal, and the axial and lateral component signals indicate a direction and a speed of the structure flowing through the tubular object.
