The present invention relates to an X-ray image magnifier having a vacuum container (1) and an electro-optical device (2). The vacuum container (1) is formed to be electrically insulated and includes: an input light emitting screen (3); a photoelectric negative electrode (4) which is arranged on the lower part of the input light emitting screen (3) and emits electrons (e-); and an output light emitting screen (5). The electro-optical device (2) includes electrodes (21, 22, 23, 24) in the number which can be set. According to an embodiment of the present invention, the electrodes (21, 22, 23, 24) of the electro-optical device (2) are arranged on at least portions of an outer side of the vacuum container (1). Therefore, assembling costs of the X-ray image magnifier is significantly reduced; and thus a simpler structure can be provided to the X-ray image magnifier. |
