방사선치료 시 자세와 device에 따른 호흡신호의 분석

초록

This study statistically analyzed the difference of the stability of maintaining a respiratory period shown according to position and use of a device to search the tendency and usefulness of a device. The supine position showed better maintaining respiratory cycles than the prone position. The 85% of subjects who showed bad maintenance pattern of a respiratory cycle were significantly different pattern with using belly board. It could be said that there was a significant correlation between the maintenance of a respiratory cycle and relative index of respirational stability(p=0.044, kappa=0.607). The movement due to respiration was one of important considerations in the radiation therapy on chest, abdomen, and even pelvis. This study could contribute to the high quality radiation therapy by statistic analysis of respiratory signals and its application.
