Abstract

An image capturing apparatus establishes a communication link with one console and transmits obtained radiographic image information to the one console. The one console includes a backup unit therein. The backup unit includes means (network monitoring unit, backup data storage unit) for monitoring a network, reading the radiographic image information during transmission thereof via the network, and temporarily storing the read radiographic image information as backup data, and means (supplementary data extraction unit, supplementary data transmitter) for transmitting to another console as supplementary data a portion or all of the backup data, in accordance with a data supplementing request from the other console.

Claims

a portion or all of the plurality of image capturing apparatus each include respectively a communication device for establishing a communication link with one of the controllers from among the plurality of controllers, and transmitting the obtained radiographic image information to the one controller;

the plurality of controllers each include respectively a backup unit therein, which is operated in the case that the communication link is not established;

the backup unit comprising;

a unit for monitoring the network, reading the radiographic image information during transmission thereof via the network, and temporarily storing the read radiographic image information as backup data; and

a unit for transmitting a portion or all of the backup data to the one controller as supplementary data in accordance with a data supplementing request from the one controller.

2. The radiography network system according to claim 1, wherein the backup unit further comprises:

a network monitoring unit for monitoring the network and reading the radiographic image information during transmission thereof via the network;

a backup data storage unit for temporarily storing the read radiographic image information in a memory as backup data;

a supplementary data extraction unit for extracting as supplementary data all of the backup data that is stored in the memory, or an object part of the data supplementing request from among the backup data, based on the data supplementing request from the one controller; and

a supplementary data transmitting unit for transmitting the extracted supplementary data to the one controller.

3. The radiography network system according to claim 1, wherein the radiographic image capturing system further comprises:

a plurality of image capturing apparatus, which each utilize a radiation detector for detecting radiation that has passed through a subject in a radiographic image capturing process and converting the radiation into radiographic image information, and a plurality of controllers for controlling the image capturing apparatus based on image capture command information supplied from the exterior,

wherein the plurality of image capturing apparatus and the plurality of controllers are interconnected by a wireless network, and

wherein the plurality of image capturing apparatus each include the communication device therein, respectively.

4. The radiography network system according to claim 1, wherein the radiographic image capturing system further comprises:

at least one first image capturing apparatus utilizing a radiation detector that detects radiation having passed through a subject in a radiographic image capturing process and converts the radiation into radiographic image information, at least one second image capturing apparatus utilizing a stimulable phosphor panel that detects radiation having passed through a subject in a radiographic image capturing process, converts the radiation into radiographic image information and stores the radiographic image information therein, at least one image reading apparatus for reading the radiographic image information from the stimulable phosphor panel, and a plurality of controllers for controlling any of the first image capturing apparatus, the second image capturing apparatus, and the image reading apparatus based on image capture command information supplied from the exterior,
