Abstract: To compare and analyze the effects of VAMT plan based on Monaco treatment plan system and Tomo treatment plan system based on spiral tomography system on cervical cancer dosimetry. [Methods] Ten patients with cervical cancer who received cervical cancer radiotherapy from September 2017 to May 2018 were selected, using the VAMT plan based on MonacoTPS and the Tomo plan based on TomoHTMV2.0.5 TPS. Target dosimetry index, endangered organ dosimetry index, machine jumps, and patient treatment time. [Result] The conformity index CI of the target area of the TOMO plan is (0.85±0.02) and the uniformity index HI is (0.07± 0.01), which are better than the CI (0.80±0.01) and HI (0.10±0.01) of the VAMTMonaco plan. The difference is highly statistically significant (p
