1. Apparatus comprising: an imaging device including an emitter, a collimator, a detector, and a support assembly, the collimator and detector being mounted on the support assembly and being rotationally movable independent of the support assembly, wherein rotation of the collimator matches rotation of the detector and an axis of rotation of the collimator is the same axis of rotation of the detector, and a display for presenting an image to an operator, and image orientation logic which displays a target anatomy in a selected orientation in response to user input so that the orientation is presented regardless of orientation of the target anatomy relative to the detector, and regardless of rotation of the detector.
