摘要： A method and a device of controlling the position of the X-ray tube of a computed tomography (CT) system may include: acquiring an AP signal output by an AP sensor of the CT system, an IP signal output by an IP sensor and encoder data output by a motor, determining a homing positioning signal AP0 of the AP signal based on the AP signal and the IP signal, where the homing positioning signal AP0 is used to determine the starting point of the period of rotation of the X-ray tube, utilizing the encoder data to calculate the encoder data containing AP signal based on the determined homing positioning signal AP0, where the encoder data containing AP signal is the AP signal processed by use of the encoder data, and controlling the position of the X-ray tube based on the encoder data containing AP signal.

摘要： A tuning method for a collimator of a CT machine, which, in each cycle of X-ray scan operation and stop, may include determining whether an X-ray is generated from the anode plate; calculating the Z-direction heating displacement of the slot plate during the current scan based on a detected X-ray, driving the slot plate to move by the heating displacement in the Z-direction, calculating the total Z-direction heating displacement of the slot plate at the end of the current scan, calculating the cooling displacement of the slot plate during the current stop based on the stop time of the X-ray, and driving the slot plate to move.
