SUSPENSION DEVICE FOR TOP BOARD SUPPORT MECHANISM, X-RAY COMPUTERIZED TOMOGRAPHY APPARATUS AND METHOD FOR REDUCING DEFLECTION

PROBLEM TO BE SOLVED: To reduce deflection of the top board in the imaging area and to form a foothold just under the top board supporting mechanism.SOLUTION: The suspension device for top board support mechanism includes a top board supporting mechanism for movably supporting the top board, a plurality of suspension members which suspend the top board supporting mechanism from the ceiling and whose length can be changed, a plurality of suspension member driving units which change the length of each suspension member, a measurement section for measuring the deflection of the top board moved by the supporting mechanism, and a drive control section for controlling the length of the plurality of the suspension members separately according to the deflection of the top board.
