1. A method for controlling a medical device, comprising:
obtaining position information of one or more ionization chambers of a scanning device, the scanning device being configured to scan a target object;
determining a detection region of at least one ionization chamber of the one or more ionization chambers based on the position information of the one or more ionization chambers;
determining projection data of a projection device, the projection data including image data corresponding to the detection region of the at least one ionization chamber;
controlling the projection device to project the projection data onto the target object;
obtaining a reference image of the target object, the reference image being captured by a camera after the projection device projects the projection data onto the target object to be scanned, and the reference image including a projection region corresponding to the detection region of the at least one ionization chamber and a region of interest to be scanned of the target object; and
determining, from the one or more ionization chambers based on the projection region and the region of interest in the reference image, one or more target ionization chambers to be operated during a scan of the target object.
