Claim 11:
12. A device of controlling the position of an X-ray tube of a computed tomography (CT) system, comprising:
a memory storing executable instructions; and
a processor configured to execute the instructions to:
acquire an angular position (AP) signal output by an AP sensor of the CT system, an index pulse (IP) signal output by an IP sensor and encoder data output by a motor,
determine a homing positioning signal of the AP signal based on the AP signal and the IP signal, wherein a starting point of a period of rotation of the X-ray tube is determinable based on the homing position signal,
calibrate the AP signal based on the determined homing positioning signal and the encoder data to determine a calibrated AP signal, and
control the position of the X-ray tube based on the calibrated AP signal.
