摘要： A method may include obtaining a feedback or a reference value of a tube voltage applied to a radiation source of a radiation device for generating radiation rays. The method may also include determining, based on the feedback or the reference value of the tube voltage, a specific value of a focusing parameter associated with a focusing device of the radiation device. The method may further include causing the focusing device to shape a focus of the radiation rays according to the determined value of the focusing parameter. The focus of the radiation rays may satisfy an operational constraint under the specific value of the focusing parameter.

摘要： The present disclosure provides an arcing detection device. The arcing detection device may include a detection coil and a processing circuit operably connected to the detection coil. The detection coil may be configured to detect a current variation of a system. The processing circuit may be configured to determine information of an arcing event of the system based on the current variation of the system. The information of the arcing event of the system may include a position where the arcing event occurs in the system.
