Abstract: The disclosure provides a detector, and a detecting system and method for dividing energy regions intelligently. The detecting method may comprise: collecting, by a detector, rays transmitted through a detected object and generating a detection signal according to the rays; wherein each column of pixels of the detector comprises one class-A electrode and a plurality of class-B electrodes, and the class-A electrode and the class-B electrodes are arranged sequentially in a moving direction of the detected object, such that the rays transmitted through the detected object firstly enter into the class-A electrode and then into the class-B electrodes; obtaining image data of the detected object based on the detection signal corresponding to the class-A electrode, and estimating a material component of the detected object based on the image data; adjusting one or more thresholds for dividing the energy regions according to the estimated material component; and determining energy regions to which the detection signal corresponding to the class-B electrodes belongs, according to the adjusted one or more thresholds, and calculating a number of signals in each energy region, so as to obtain the image data of the detected object and determine components of the detected object accurately.
