Results of IVD Tests for IMRT Techniques Applied to 2 Anatomical Sites.^a

IMRT
Anatomical site	#P	#T	P($\overline{\text{R}}$) %	T(R) %	P($\overline{\gamma }$%) %	T(γ%) %	P(${\overline{\gamma }}_{\text{mean}}$) %	T(γmean) %
Pelvis (5%, 5 mm)	60	1624	100	95	100	93	100	99
H&N (3%, 3 mm)	18	1100	100	98	100	93	100	99

Abbreviations: H&N, head neck; IMRT, intensity-modulated radiotherapy.

^a #P and #T are the number of patients and tests, respectively. P($\overline{\text{R}}$), P($\overline{\gamma }$%), and P(${\overline{\gamma }}_{\text{mean}}$) correspond to the percentages of patients (P) within tolerance $\overline{\text{R}},\overline{\gamma }$, and ${\overline{\gamma }}_{\text{mean}}$ and T(R), T(γ%), and T(γ_mean) are the percentages of tests (T) within tolerance R, γ%, and γ_mean, respectively. Of all, 191 (7%) of 2724 tests resulted in OTL.
