Abstract: An ultrasound diagnostic imaging system (10) is provided that includes a patient monitor (12) and an ultrasound machine (14). The patient monitor (12) includes a communications processing unit (16) with a sensor interface (18) for receiving physiological data and a wireless interface (20) for transmitting ultrasound control data to the ultrasound machine (14). The patient monitor (12) further includes a data processing unit (24) that generates ultrasound control data in response to physiological data received by the sensor interface (18). The ultrasound machine (14) includes a communications processing unit (30) with a wireless interface (32). The communications processing units (16, 30) establish a low-latency wireless communication link that allows ultrasound control data sent by the patient monitor (12) to trigger the acquisition of ultrasound frames, images, and/or volumes at an appropriate time during a physiological cycle.
