Beam-quality of medical linac evaluations vary by diverse factors. Because conventional beam-quality evaluation methods yield fragmentary results, a new beam-evaluation method is suggested, and its feasibility is evaluated. The PDDs (percentage depth doses) of 6 MV (Mega-voltage) and 10 MV photon, R (Range) of a 6 MeV (Mega Electron-voltage) and 9 MeV electron were measured and compared with the conventional evaluation methods, and the improved methods PDD<SUP>10</SUP><SUB>5</SUB>, PDD<SUP>20</SUP><SUB>10</SUB>, PDD<SUP>30</SUP><SUB>20</SUB>, PDD<SUP>20</SUP><SUB> 5</SUB>, PDD<SUP>30</SUP> <SUB>10</SUB>, and R<SUP>70</SUP> <SUB>50</SUB>, R<SUP>50</SUP> <SUB>30</SUB>, R<SUP>70</SUP><SUB>30</SUB> as the magnetic field of the bending magnet was changed to +2% to ?2%, and the results were compared. The comparison showed that the improved methods exhibit a higher discrimination than the conventional methods in each energy regime. PDD<SUP>10</SUP><SUB>5</SUB>, PDD<SUP>30</SUP><SUB>20</SUB>, PDD<SUP>30</SUP><SUB>10</SUB> and R<SUP>70</SUP><SUB>50</SUB>, R<SUP>50</SUP><SUB>30</SUB> should be applied. These methods exhibit a higher discrimination in each energy regime than conventional beam-quality evaluation methods; therefore, they should be used for beam-quality evaluation according to the magnetic field variation.
