Claim 0:
1. A method of operating a radiation apparatus, the method comprising:
selecting at least a first angle and a second angle from a set of angles for a first rotation of a gantry of a radiation apparatus, wherein the first angle is selected from the set of angles based on having a tracking quality metric value satisfying a tracking quality metric criterion, wherein the tracking quality metric value includes a numerical value representing a confidence that a target is trackable based on images generated at the first angle, and wherein the tracking quality metric criterion includes a numerical threshold;
generating, using an imaging device mounted to the gantry, a first tracking image of the target from the first angle during the first rotation of the gantry; and
generating, using the imaging device, a second tracking image of the target from the second angle during the first rotation of the gantry.
