    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.

    Abstract: This invention provides a scan method, scan system and radiation scan controller, and relates to the field of radiation. Wherein, the scan method of this invention comprises: obtaining detection data of an object to be inspected under radiation scanning using a detector; adjusting an accelerator output beam dose rate and/or an output electron beam energy level of a radiation emission device according to the detection data. With this method, working conditions of the accelerator of the radiation emission device may be adjusted according to the detection data detected by the detector, so that for a region having a larger mass thickness, a higher output beam dose rate or a higher electron beam output energy level is adopted to guarantee satisfied imaging technical indexes, for a region having a smaller mass thickness, a lower output beam dose rate or a lower electron beam output energy level is adopted to reduce the environmental dose level while guaranteeing satisfied imaging technical indexes.
