Abstract
Cycle information is detected with ultrasound. For example, a breathing cycle is detected from frames of ultrasound data acquired over time. Motion relative to a reference frame is tracked in other frames of data. The variation in motion identifies the cycle. The cycle is then displayed for diagnostic purposes, triggers acquisition of ultrasound images, used for altering other processes or calculations or used for performing another act.
