1. An apparatus, comprising:
a data storage device to store a plurality of displacement points of an external marker indicative of the motion of the external marker during a periodic cycle; and a processing device coupled to the data storage device, the processing device to determine a specified time in the periodic cycle, which corresponds to a first phase of the periodic cycle, in which to acquire an image of a target based on the plurality of displacement points, and to transmit a signal to automatically trigger an imaging system to acquire the image of the target at the first phase of the periodic cycle.
