摘      要：Respiration-induced intra-fractional motion a ects the actual radiation dose delivered to the tumor definitely,resulting in insufficient local control or severe damage to critical *** mitigate the impact of intra-fractional motion,many approaches such as respiratory gating,tumor tracking,breath hold and motion-encompassing methods have been proposed.
