摘要： PROBLEM TO BE SOLVED: To securely collect projection data for reconstructing a CT image at a slice position on the outer side of the range for linear movement. SOLUTION: A retention time τ, in which only the "rotation" is performed but the "linear movement" is not performed at the starting point Zs and the ending point Zf of the linear movement, is set when the projection data are collected by linearly moving an X-ray tube and a multi-detector while rotating them. By adjusting the retention time τ, the projection data in the view angle range necessary for reconstructing a CT image at a slice position on the outer side of the linear movement range can be securely collected even if the speed of rotation is slow or the speed of the linear movement is fast.
