Abstract

Apparatus for adaptively scheduling ultrasound device actions includes a probe interface, a beamer, a receiver, a processor, and a memory. The probe interface may interface with probe units to transmit signals generated by the beamer to the probe units and to receive data signals from the probe units. The processor may be coupled to the probe interface, the beamer, and the receiver. The memory may store instructions, which when executed by the processor, causes the processor to generate a task list that includes a timed beam firing sequence and to signal to the beamer to generate signals to the probe units associated with the plurality of task actions. The task list may include a plurality of task actions associated with probe units, and the processor may signal to the beamer in accordance with the timed beam firing sequence. Other embodiments are also described.
