1. A method for an imaging system, comprising:
generating a depth map from data provided by a first device of a set of devices, wherein generating the depth map includes:
obtaining 3-dimensional (3D) image data from the first device; and
using a known distance from a detector of the imaging system to a patient positioned below the detector, a known distance from the set of devices to the patient, and a collimator iris geometry to create 3D point cloud data;
matching the depth map to a field-of-view (FOV) estimation provided by a second device of the set of devices to generate a complete FOV preview; and
displaying the complete FOV preview on at least one display device.
