Abstract:: Abstract: Relatively ideal target and organs-at-risk doses can be achieved using traditional body surface marker line combined with bone or soft tissue calibration in image-guided radiotherapy (IGRT) of prostate cancer (PCa). However, the traditional method is not reliable when stereotactic radiotherapy is carried out. Surgically implanted or natural fiducial marker (FM) can replace the traditional method to provide high-precision positioning verification for PCa IGRT. The review on FM characteristic, implantation, clinical application and gain shows that there are many types of commercial FM with different characteristics, exhibiting high safety and stability after implantation, which is of great significance to improve the efficacy of PCa IGRT.
