Relative difference of mean dose (a) and difference of V70 (b) and V100 (c) between the reference and registered floating lesions using the CNN&LM-guided or CNN-guided CT to CT registration. MAA: the reference lesions. CNN&LM: the floating lesions registered by the CNN&LM-guided registration. CNN: the floating lesions registered by the CNN-guided registration. The relative difference of mean dose is computed by (mean dose (floating) – mean dose (reference)/mean dose (reference)). The difference of V70 and V100 is computed by (V70 or V100 (floating) – V70 or V100 (reference))
