Abstract: Disclosed is a process for preparing a radiation image storage panel having a phosphor layer containing an activated stimulable phosphor, characterized in that applying a heat treatment that can secure the content of an activator in the activated stimulable phosphor.Disclosed is also a process for preparing a radiation image storage panel having a layer of a stimulable phosphor layer activated with an activator, wherein a stimulable phosphor matrix layer is formed, and thereafter the activator is diffusion added to the layer to form a stimulable phosphor layer.
Abstract: A radiation image storage panel which comprises a support and a light-shielding layer, a light-scattering layer and a stimulable phosphor layer formed on the support in succession.According to this invention, a radiation image storage panel provides radiation images that are high in radiation sensitivity and sharpness.
Abstract: When documents fed by an automatic document feeder are subjected to the first copying operation, the documents are counted one by one. Alternately, the total number of documents are calculated by dividing the number of copy paper sheets sent to an intermediate tray, by the preset number of copies. Page entry is made in the copy paper sheets taken out from the intermediate tray, based on the total number of documents thus obtained. The total number of documents may be automatically counted. Accordingly, even though the documents are successively fed, starting from the last-page document, page entry may be made. The operator is not required to manually count the total number of documents.
Abstract: Disclosed is a radiation image storage panel, which comprises a support, a flame-sprayed layer and a stimulable phosphor layer formed by a vapor phase build-in method in succession and method for preparing the same. According to this invention, radiation images which are high in radiation sensitivity and sharpness can be obtained.
Abstract: A method for preparing a radiographic image conversion panel and the panel prepared thereby is disclosed. In the method a vapor flow of photostimulable phosphor or its raw material is applied to a support at a particular angle of incidence with respect to the normal direction of the support.
Abstract: Disclosed is a radiation image storage panel comprising a heat generating body for drying assembled in a radiation image storage panel using a light stimulable phosphor.According to this invention, a radiation image storage panel which can stand uses for a long term can be obtained.
Abstract: 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.
