Description

This invention relates to a radiography system, a radiography apparatus, and a control device. In the medical field, radiation imaging systems utilizing radiation are well-known. With the digitalization of radiation imaging systems, systems have become widespread where radiation is directed from the subject to the imaging device, the device generates digital images, and the image control system allows for immediate image verification. This improves the workflow compared to traditional film-based imaging methods, enabling faster imaging cycles. In such radiography systems, devices have been disclosed that wirelessly connect the radiography apparatus and the imaging control device, eliminating the installation limitations imposed by cables on the radiography apparatus. To establish this wireless connection between devices, the SSID (Service Set Identifier), authentication method, encryption type, and encryption key must be identical on both connected devices. Typically, these settings are configured manually on both wirelessly connected devices, or using a push-button or PIN code method as defined by WPS (Wi-Fi Protected Setup). However, manual setup requires manual input, and errors during this process can prevent connection establishment. Similarly, the PIN code method requires manual input of the PIN code on the master unit. Furthermore, the push-button method requires simultaneous pressing or contact of the push buttons on both the master and slave units, deviating from the normal workflow for a radiography system. Therefore, Patent Document 1 discloses a means for wirelessly configuring settings between a radiography apparatus and an imaging control device via a connection means using short-range wireless communication such as infrared communication or Bluetooth®, which has a narrower communication range than wireless communication. This eliminates the need for the operator to manually configure the wireless settings. Japanese Patent Publication No. 2011-120885 This is an example of the configuration of a radiography system according to the first embodiment.This is an example of the configuration of a radiography apparatus according to the first embodiment.This is a flowchart showing the operation of the radiography system according to the first embodiment.This is a sequence diagram illustrating the operation during connection destination determination according to the first embodiment.This is an example of the arrangement of each device according to the first embodiment.This is a sequence diagram illustrating the operation of an observer in the first embodiment, where the observer is a radiography device. (First embodiment) Embodiments of the present invention will be described in detail with reference to Figures 1 to 6. First, an example of the configuration of the radiography system 100 according to this embodiment will be described using the conceptual diagram in Figure 1. The radiography system 100 includes a radiography device 101, an information processing device 102, an access point 103, a communication device 104, a synchronization control device 105, and a radiation generator 106. The radiography apparatus 101 is a device that captures a radiographic image based on radiation 107 transmitted through the subject H. This radiography apparatus 101 may be, for example, a portable radiography apparatus. The radiography apparatus 101 has, for example, a two-dimensional pixel array in which a phosphor that converts radiation into light and pixels that convert light into electric charge are arranged, thereby converting the incident radiation into electric charge. The converted electric charge is processed as image data and sent to the information processing apparatus 102. The information processing device 102 is a control device implemented using known technologies such as a general-purpose computer, and includes a display unit, an input unit, and a control unit. The information processing device 102 performs image processing for correction, storage, and display of image data received from the radiography apparatus 101. In this case, some or all of the image processing functions may be performed by the radiography apparatus 101. Furthermore, the information processing device 102 displays radiographic images to the operator via a display unit and provides instructions for imaging. The information processing device 102 also has an input unit that allows the operator to input instructions regarding imaging conditions. The control unit of the information processing device 102 has functions such as comparing acquired signal strength with thresholds, responding to connection requests, and transmitting information for communication via the wireless communication unit, such as wireless information described later. The access point 103 is a device that relays radio waves for wireless information exchange between the radiography apparatus 101 and the information processing apparatus 102. In Figure 1, the access p
