SYSTEM AND METHOD FOR FLEXIBLE RATE PROCESSING OF ULTRASOUND DATA
The invention is directed at a method and system for flexible rate processing of ultrasound data. In one embodiment, the method includes acquiring ultrasound data at a data acquisition rate; setting an inter-frameset data rate; selecting frames from acquired ultrasound data to form a plurality of framesets, where the framesets are spaced according to the inter-frameset data rate; and processing the data at the controlled data rates. In another embodiment, the system includes a data acquisition controller that collects ultrasound data at an acquisition rate; a memory that stores the ultrasound data; and a data processor that selects framesets at an inter-frameset data rate, wherein a frameset is a set of frames selected from memory, performs processing on a frameset, and outputs processed data at a product rate.
