Abstract
Official abstract text for this publication.
There is provided a radiation detector including: a radiation detection unit that generates and outputs a radiation image from an electric charge generated in response to emitted radiation; and a communication unit that operates as a master to perform wireless communication with a slave and that is prevented from being directly connected to a global network, in a case of transmitting the radiation image generated by the radiation detection unit.
First claim
Opening claim text (preview).
What is claimed is: 1 . A radiation detector comprising: a detector that generates and outputs a radiation image from an electric charge generated in response to emitted radiation; and a communicator that transmits the radiation image generated by the detector and has an operational setting that can be switched between a first state in which the radiation detector operates as a master to perform, via the communicator, wireless communication with a slave that is external to the radiation detector and a second state in which the radiation detector operates as a slave to perform, via the communicator, wireless communication with a master that is external to the radiation detector, and (A) in a case in which the operational setting of the communicator is in the first state, the communicator is prevented from being directly connected to a global network, and (B) in a case in which the operational setting of the communicator is in the second state, the communicator is allowed to be directly connected to the global network. 2 . The radiation detector according to claim 1 , further comprising: at least one processor, wherein the processor is configured to, among a first power consumption reduction mode in which power from a power supply is supplied to at least the communicator and supply of the power from the power supply to a part of the radiation detector other than the communicator is cut off, and a second power consumption reduction mode in which supply of the power from the power supply to the communicator and the part of the radiation detector other than the communicator is cut off, transition to the first power consumption reduction mode in a case in which the communicator operates as the master. 3 . The radiation detector according to claim 1 , further comprising: at least one processor, wherein the processor is configured to, among a first power consumption reduction mode in which power from a power supply is supplied to at least the communicator and supply of the power from the power supply to a part of the radiation detector other than the communicator is cut off, and a second power consumption reduction mode in which supply of the power from the power supply to the communicator and the part of the radiation detector other than the communicator is cut off, prohibit transition to the second power consumption reduction mode in a case in which the communicator operates as the master. 4 . The radiation detector according to claim 1 , further comprising: at least one processor, wherein the processor is configured to prohibit transition to a power consumption reduction mode in which supply of power from a power supply to the communicator and a part of the radiation detector other than the communicator is cut off, in a case in which the communicator operates as the master. 5 . The radiation detector according to claim 1 , wherein the communicator serves as an access point for wireless communication in a case in which the communicator operates as the master. 6 . A control method for a radiation detector including a detector that generates and outputs a radiation image from an electric charge generated in response to emitted radiation and a communicator that transmits the radiation image generated by the detector and has an operational setting that can be switched between a first state in which the radiation detector operates as a master to perform, via the communicator, wireless communication with a slave that is external to the radiation detector, and a second state in which the radiation detector operates as a slave to perform, via the communicator, wireless communication with a master that is external to the radiation detector, the control method comprising: (A) in a case in which the operational setting of the communicator is in the first state, preventing the communicator from being directly connected to a global network; and (B) in a case in which the operational setting of communicator is in the second state, allowing the communicator to be directly connected to the global network.
