    摘要: A radiation image information reading method includes scanning a stimulating ray on a radiation image converting panel surface to obtain radiation image information stored on the radiation image converting panel, the scanning step including performing scanning of the stimulating ray while repeating successively irradiation and stopping thereof. In this manner, the noise caused by fluorescent afterflow, stimulation afterglow, stray light from outside of the apparatus or a laser beam, etc., can be removed simply and correctly. A visible image which is correct with good reproducibility corresponding to the real image, and also good in sharpness, can be obtained, whereby diagnosis with high reliability by means of a radiation image is rendered possible. In one embodiment, only image signals detected during periods of irradiation by the stimulating ray are read. In another embodiment, the difference in image signals read during irradiation and during stopping of the stimulating ray is used as the image information.

    摘要: There are disclosed a radiation image storage panel which comprises a stimulable phosphor layer on a support, wherein the stimulable phosphor layer has a fine pillar-shaped block structure, and a process of making a radiation image storage panel having a stimulable phosphor layer on a support, which comprises getting the stimulable phosphor layer having a fine pillar-shaped block structure. Scattering of the stimulation exciting light within the stimulable phosphor layer of the present invention can be markedly reduced since the stimulable phosphor layer has a block structure shaped in fine pillars, whereby it is possible to improve sharpness of the image. Also, radiation sensitivity and graininess of the image can be improved by enlargement of the stimulable phosphor layer without lowering sharpness of the image since lowering in sharpness of the image due to increase of the stimulable phosphor layer is little.
