Document Type and Number:
Japanese Patent JP2509814
Kind Code:
B2
Abstract:
PURPOSE:To remove the influence of a shoulder dragging phenomenon and to form a radiation image of high quality by finding the size of a shoulder dragging occurrence area of the stimulated phosphorescent body previously and removing the shoulder dragging phenomenon occurrence area when an image is read out of the stimulated phosphorescent body. CONSTITUTION:The size of the shoulder dragging phenomenon occurrence area of the stimulat ed phosphorescent body is determined previously and the (x)- and (y)-directional area dimensions are found from calculation expressions to specify the shoulder dragging phenome non occurrence area. It is considered that is removed when stimulated phosphorescent light from the stimulated phosphorescent body is converged by a converging body. In this case, the stimulated phosphorescent light from the stimulated phosphorescent body 4 is guided to a photodetector to set the width of the converging body to the length of an effective image recording area 33a in the (x) direction and perform control in a (y) direction by feeding the stimulated phosphorescent body 4 in the (y) direction. Further, when image information which is converted into digital data is stored in a memory, the stimulated phosphorescent light converged by the converging body is converted by the photodetector into an electric signal, which is inputted to a signal processing part as image information and converted into digital data and stored in the memory. Consequently, a radiation image of high quality is obtained.
