    Fiducial marker (FM) has been widely used in image guided radiotherapy (IGRT) for prostate cancer. The image matching and calibration technology based on FM has improved the accuracy of target location in prostate cancer IGRT. The technology above enables patients to achieve higher treatment gains. The accurate identification of FM in prostate cancer IGRT is an important prerequisite for achieving its clinical value. The identification method is mainly X-ray imaging technology. In the identification of FM mainly based on CT imaging technology, the type of FM is gradually developed from solid to liquid, and the level of identification automation and accuracy is gradually improved. In the identification of FM assisted by C-arm X-ray imaging technology, the identification results can meet the clinical need. The identification of liquid FM based on CT has the maximum advantage and the minimum limitation. This technology will become the focus of future research and application in prostate cancer IGRT. This paper reviewed the advantages, disadvantages, and application progress of FM identification based on CT and C-arm X-ray machine, so as to provide theoretical and practical references for medical professionals in related fields such as medical imaging, radiotherapy, and urology.
