Abstract:
Objective To discuss errors of conformal plumbic blocks made with manual cutter and automatic cutter.Methods According to beam files of Treatment Planning System,the conformal plumbic blocks were made with manual cutter and automatic cutter respectively.Then their errors were measured.Results With manual cutter,the errors of conformal plumbic blocks were 2.355 mm.With automatic cutter,the errors of conformal plumbic blocks were 1.425 mm.Conclusion The errors of conformal plumbic blocks made with automatic cutter are less than the errors of conformal plumbic blocks made with manual cutter,so automatic cutter should be a necessary tool in making conformal plumbic blocks.
