Purpose : To analyze tumor`s movement and volume change from changing position in order to minimize movement caused by breathing.

Materials and Methods : We conducted survey of 14 patients with HCC(Hepatocellular carcinoma). Patient immobilization
device was made in two ways(Supine position, prone position) and from image acquisition, tumor`s movement, volume and dose are analyzed.

Results : The mean movement of target(LR, Left-right) in supine position and prone position was 2.76¡¾1.25 mm, 2.21¡¾0.93
mm. AP(Anterior-posterior) and SI(Superior-inferior) was 4.02¡¾1.63 mm, 11.56¡¾3.08 mm, and 3.36¡¾1.17 mm, 7.45¡¾1.96
mm. Treatment volume was decreased and normal liver volume was increased in prone position.

Conclusion : We could reduce the margin of the treatment volume by minimizing the movement of liver caused by breathing. Especially in prone position, it is considered to be able to decrease the movement of the liver and increase normal liver volume.
