Abstract :
Four-dimensional (4D) computed tomography (CT) can be used in radiation treatment planning to account for respiratory and organ motion. Current 4D CT techniques have limitations in either spatial or temporal resolution. In addition, 4D CT increases the radiation dose to the patients. The purpose of this study is to accurately predict images using 4D CT scan with the contour and projection imaging system.
