 Abstract
Comparison of the dose aspect that radiation therapy treatments using IMRT, tomotherapy, mArc (modulated arc therapy). The experimental subject is non-small cell lung cancer patient. The prescription dose is 58.0 Gy to the volume of PTV(planning target volume). and spinal cord, esophagus, and liver organ is the normal organ(OAR, organ at risk). Average PTV value is 57.60 Gy in mArc and 61.04 Gy in tomotherapy and 58.95 Gy in IMRT. The average dose of the Esophagus is 2.84 Gy in m-Arc, 5.14 Gy in tomotherapy, 1.84 Gy in IMRT. The average dose of the Liver is 19.44 Gy in m-Arc, 12.22 Gy in tomotherapy, 21.97 Gy in IMRT. The average dose of the Spinal cord is 5.72 Gy in m-Arc, 7.08 Gy in tomotherapy, 6.15 Gy in IMRT. Results of this study is no significant difference between mArc and tomotherapy and Linac based IMRT in dose study and also, mArc`s dose coverage and dose volume histogram is better than IMRT and tomotherapy. but, This study is limited to a disease of cancer. in addition, fewer number of groups. The wide range the more research can be developed patient-specific treatment techniques and be applied to the patients
