An IMRT/VMAT Technique for Nonsmall Cell Lung Cancer

Table 1

Treatment planning objectives used for Hybrid IMRT/VMAT, IMRT, and VMAT plans.

PTV		>62.7 Gy
		<72.6 Gy
Normal lung		<60%
		<40%
		<30%
		<20%
	Mean dose	<16 Gy
Spinal cord	Max dose	<50 Gy
Esophagus	Max dose	<66 Gy
	Mean dose	<34 Gy
Heart		<80%
		<30%
	Mean dose	<30 Gy

PTV is planning target volume.
is percentage volume of OARs receiving at least Gy of radiation dose.
