Complete with degree. Therefore, the delivery of the thinned data to the console C3 is completed before the operator leaves the imaging room R4 by placing the radiation image detector 2 in the imaging room R4 and arrives at the console C3.
- the operator When the operator arrives at the console C3, since the thinned data is already displayed on the display unit CM of the console C3, the operator needs to immediately re-photograph the thinned data. It is possible to determine whether or not. If re-imaging is not necessary, it is possible to transmit image data corresponding to the thinned data from the radiation image detector 2 or to transmit other image data or thinned data.
- the position detection unit 6 detects the current position of the radiographic image detector 2 and transmits the information to the data management server S.
- the data management server S grasps the current position of the radiation image detector 2 and automatically selects the console C closest to the current position of the radiation image detector 2 so that the image data transmitted from the radiation image detector 2 It is possible to automatically distribute the thinned data to the console C.
- the radiographic image capturing system 1 according to the present embodiment, the convenience for the operator is improved.
- the operator since the thinned data and the like are distributed to the console C when the operator arrives at the console C, the operator immediately determines whether or not re-shooting is necessary by looking at the thinned data. Is possible. Therefore, according to the radiographic image capturing system 1 according to the present embodiment, when re-imaging is necessary, it is possible to perform re-imaging immediately, and the convenience for patients and the like is improved.
- image data or the like is transmitted to a console C different from the console C closest to the current position of the radiation image detector 2 automatically selected by the data management server S.
- the data management server S basically selects the console C that is closest to the current position of the radiation image detector 2, the console C that further transmits image data or the like on the radiation image detector 2 side. If it is configured to be able to specify freely, the convenience is further improved.
- an input unit (not shown) for designating a console C for transmitting image data and thinning data is provided on the side surface of the housing 21 of the radiation image detector 2, and the input unit or the like by the operator.
- the data management server S Can be configured to deliver image data or the like to the designated console C without selecting the console C closest to the current position of the radiation image detector 2 described above.
- console C when a different console C is designated from the same radiation image detector 2, it may be configured to deliver image data or the like to the designated console C later in time, that is, at a time close to the current time. preferable. This is because when the console C is designated later in time, it can be considered that the designation of the console C made earlier in time is corrected.
- the position detection is not limited to the method using the tag reader 6.
- the radiation image detector 2 has a small GPS (Global Positioning System) transmitter built therein, and the radiation image detector is detected by the position search. It is also possible to configure to detect two current positions.

Le système de capture d'image de rayonnement (1) comporte une pluralité d'espaces d'imagerie (R), le détecteur d'image de rayonnement (2) comportant un milieu de mémorisation (28) dans lequel une pluralité d'éléments de données d'image peuvent être mémorisés, une pluralité de consoles (C) destinées à générer des images de rayonnement en se basant sur les données d'image transmises, un serveur de gestion de données (S) qui gère la délivrance des données d'image entre le détecteur d'image de rayonnement (2) et les consoles (C) et un moyen de détection de position (6) capable de détecter la position actuelle du détecteur d'image de rayonnement (2). Lorsque le transfert des données d'image est demandé à partir du détecteur d'image de rayonnement (2), le serveur de gestion de données (S) exécute une commande de sélection de la console (C) la plus proche de la position actuelle du détecteur d'image de rayonnement (2) en se basant sur les informations liées à la position actuelle du détecteur d'image de rayonnement (2), et délivre à la console la plus proche (C) les données d'image transmises à partir du détecteur d'image de rayonnement (2).
