Abstract
A target position determination of a single-slot collimating plate and a collimator assembly are disclosed. A first measurement signal is acquired based upon of the first instance of air scanning, when the single-slot collimating plate moves a predetermined distance from a starting position to a first position in a first direction of the Z axis. A second measurement signal is acquired based upon the second instance of air scanning, when the single-slot collimating plate moves a predetermined distance from the starting position to a second position in the direction opposite to the first direction. A composite measurement signal and a composite air calibration signal are determined based upon the first measurement signal and the second measurement signal. The composite measurement signal is calibrated using the composite air calibration signal. The target position of the single-slot collimating plate is determined based upon the calibrated composite measurement signal.
