Figure 2: Comparison of intensitymodulated radiation therapy and volumetricmodulated arc therapy treatment plans using formulas for equivalent uniform dose and generalized equivalent uniform dose (generalized equivalent uniform dose). The average equivalent uniform dose for intensitymodulated radiation therapy versus volumetricmodulated arc therapy were 26.61 versus 26.16 and the average generalized equivalent uniform dose was 27.73 versus 27.12, respectively, with P ≤ 0.02. For both the equivalent uniform dose and the generalized equivalent uniform dose, the ratio of intensitymodulated radiation therapy/volumetricmodulated arc therapy was 1.02
