PROBLEM TO BE SOLVED: To provide a top board for radiology equipment, even when an incident angle of an X ray is different, capable of suppressing variation in radiotransparency and, thereby performing diagnosis by a high-precision image and diagnosis applying little X-ray exposure dose to a subject.SOLUTION: The top board for radiology equipment comprises at least: an upper surface plate on which a subject is placed and a lower surface plate disposed to face the upper surface plate at some interval apart therefrom. In a vertical cross section to the longer direction of the top board, a portion with a different plate-thickness is provided at least at a part in a breadth direction of the upper surface plate and/or the lower surface plate, and further a face-plate cross-sectional shape of the upper surface plate and/or the lower surface plate is a curved surface.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】X線の入射角度が異なっても放射線透過性の変動を抑制でき、それにより高精度な画像による診断や、被検者のX線被爆量が少ない診断などを行える放射線機器用天板を提供することを目的とする。【解決手段】少なくとも、被検者を載せる上面板と、前記上面板と間隔をもって対向配置した下面板とから構成される放射線機器用天板であって、前記天板の長手方向に対する垂直断面において、前記上面板および/または前記下面板の横幅方向の少なくとも一部に板厚の異なる部位を有し、さらには、上面板および/または前記下面板の面板断面形状が、曲面形状である構成を有する放射線機器用天板である。【選択図】図2
