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