To compare volumetric modulated arc therapy of RapidArc with robotic stereotactic body radiation therapy (SBRT) of
CyberKnife in the planning and delivery of SBRT for hepatocellular carcinoma (HCC) treatment by analyzing dosimetric parameters.
Two radiation treatment plans were generated for 29 HCC patients, one using Eclipse for the
RapidArc plan and the other using Multiplan for the CyberKnife plan. The prescription dose was 60 Gy in 3 fractions. The dosimetric
parameters of planning target volume (PTV) coverage and normal tissue sparing in the RapidArc and the CyberKnife plans were
analyzed.
