Remote exposure control device, digital radiography system and exposing method for the system

A remote exposure control device for X-ray imaging, the remote exposure control device comprising:

• control circuitry;
• a switch;
• a sensing circuit;
• and
• a touch sensor, wherein in operation,
• the touch sensor recognizes a gesture instruction of a user and the control circuitry generates control signals based on recognized gesture instructions,
• exposure is controlled by the switch,
• the sensing circuit comprises a camera configured to collect human images and acquire identification information of one or more devices of a digital radiography system through scanning,
• when the verification of human images and the verification of identification information passes sequentially, pairing of the remote exposure control device with the one or more devices of the digital radiography system is successful, and
• when the touch sensor recognizes a gesture instruction of a user, the remote exposure control device sends a control instruction to a pairing device in the digital radiography system and paired with the remote exposure control device so as to awaken the pairing device from a sleeping state or a power-off state to an exposure stand-by state.
