Abstract: Disclosed are ultrasonic contrast imaging methods and apparatus. Under a variable frame rate imaging mode, when a contrast agent is injected to a target object, the apparatus obtains ultrasonic data with a first imaging frame rate according to corresponding imaging parameters; when a predefined condition is met after the injection, it obtains ultrasonic data with another imaging frame rate other than the first imaging frame rate according to preconfigured imaging parameters associated with the predefined condition; and generates a contrast image having at least these two imaging frame rates based on the aforementioned two kinds of obtained ultrasonic data. Accordingly, contrast images can be generated by using different imaging frame rates during ultrasonic contrast imaging process, meeting lesion-observation requirements under different contrast phases.

Abstract: Disclosed are methods and apparatus for viewing a contrast-enhanced ultrasound image and a dynamic data. The method comprises: receiving a first operation, for setting a first viewing range by a first browsing step length that is multiple frames; in response to the first operation, positioning the image data to a viewing neighborhood containing the first viewing range; receiving a second operation, on the view neighborhood by a second browsing step length that is a single frame; in response to the second operation, determining a current image frame corresponding to when the second operation is performed in the viewing neighborhood, and further positioning the image data to an adjacent frame of the current image frame to the user to view frame by frame. As such, doctors are helped to accurately locate desired image frames to significantly improve browsing efficiency with convenient operation and high user-friendliness to save time and reduce workload.
