Abstract
A method of resection-based positioning of a rotating fan beam transmitter is provided. The fan beam is rotating about a single axis of rotation. The rotating fan beam is being detected in a detector space including a detector cluster further including a plurality of detectors. The single axis of rotation intersects a reference plane in the detector space at an arbitrary angle. The method comprises: (A) detecting the rotating fan beam by using a plurality of detectors; (B) processing a set of detection signals to obtain a set of time-strike tags; and (C) determining the axis of rotation of the rotating fan beam in the detector space by using the set of time-strike tags. At least minimum number of detectors is stricken by the rotating fan beam. Each stricken detector generates a detection signal having a time-strike tag corresponding to a timing coordinate of the strike by the rotating fan beam.
