The present disclosure is related to systems and methods for monitoring a medical device. The medical device may include a tube configured to generate radiation rays and a detector configured to receive radiation rays emitted from the tube. The tube may include an anode target and a filament. The detector may include a plurality of detecting units. The method may include obtaining imaging data acquired by the detector via detecting radiation rays emitted from the tube. The method may also include determining a first feature parameter associated with the radiation rays based on the imaging data. The method may further include monitoring the medical device based on the first feature parameter associated with the radiation rays.
