ABSTRACT:
Ultrasound imaging data is collected at an adjustable collection image frame rate. Echoes produced from transmission of ultrasound energy into a subject's body are processed by an image frame acquisition device to produce a series of image frames. Each image frame comprises data representing an image of a portion of the subject's body at a given time. The image frames include collection image frames and interrogation image frames. The interrogation image frames are for sampling the subject's body between collection of at least some collection image frames. The difference between the current image frame and at least one preceding image frame is determined and a frame correlation coefficient is output based upon the difference. The collection image frame rate of the image frame acquisition device is adjusted in inverse proportion to the most recent frame correlation coefficient.
