摘要： For the purpose of reducing a deviation in the rotational center of scan and a deviation in scan position in the direction of length of a rail, a gantry system including a pair of runway rails and a gantry in an X-ray CT system that can move along the runway rails, is characterized by comprising a linear guide rail arranged in the direction along the runway rails and linear guide blocks mounted on the gantry and slidably fitted on the linear guide rail.
