Abstract:
Objective To investigate precision error between Varian auri-point localization system and Tosplane digital-bed localization system. Methods Varian Eclipse localization method and Topslane localization method were used separately to locate one target area for one same patient. Then deviations on the tumor center coordinate were measured under the simu- lation localization machine. Results Under two localization methods, the length error: 1.7mm ?0.3mm; the width error: 0.5mm?0.4mm; the altitude error: 1.2mm?0.4mm. Conclusion The curative effect of radiotherapy would be improved by applying the Topslane localization bed to the Varian Eclipse plan system.
