    Detailed Description



    [0031] Now, various embodiments of this invention will be described in detail with reference to the drawings. However, these embodiments are not intended to limit this invention, and modifications of the structures, methods or functions of these embodiments by those skilled in the art shall fall into the protection scope of this invention.

    [0032] As shown in Figures 1-2, in a first embodiment of this invention, a digital radiography system comprises: an X-ray source 10, a remote exposure control device 20, a flat panel detector (FPD) 30 and a console 40.

    [0033] One or more of the X-ray source 10, the FPD 30 and the console 40 may be paired with the remote exposure control device 20. After being paired with the remote exposure control device 20, the X-ray source 10, the FPD 30 and the console 40 may be called as pairing devices. The remote exposure control device 20 may communicate with the pairing devices and send communication data to the pairing devices. Of course, the remote exposure control device 20 may communicate with at least one of the pairing devices according to the needs.

    [0034] In this way, the remote exposure control device 20 may interact with and remotely control the pairing devices, simplifying the operation procedures for the digital radiography system. For the ease of understanding, an example is described in which the FPD 30 is the pairing device. It should be understood that the X-ray source 10 and the console 40 may also interact with and control the remote exposure control device 20 as the FPD 30 does.

    [0035] Further, the X-ray source 10 includes a tube assembly 101 and a high voltage generator 103, and may be connected to the console 40 by a cable. Generally, after the console 40 configures the parameters for the X-ray source 10 (for example, different human parts require different exposure parameters), exposure may be performed by a switch of the remote exposure control device 20. Of course, in this embodiment, the X-ray source 10 may be configured by the remote exposure control device 20 instead of the console 40, as shown in Figure 2.

    [0036] By exposure of the X-ray source 10, corresponding image information is acquired from and may be output from the FPD 30 in a visible manner for users.

    [0037] As shown in Figure 3, the remote exposure control device 20 may be a hand switch, a foot switch or the like.

    [0038] A hand switch is exemplified in this embodiment. Mechanically, the hand switch includes a body 201 for holding, a mechanical two-stage pressing switch 203 provided on the body 201, an input keyboard 205, a display screen 207, indication lamps 209, a fingerprint recognition area 211 and a touch sensing area 212. It can be understood that the two-stage pressing switch 203 may be provided as a non-mechanical one, the input keyboard 205 may not be physical keyboards (and may be provided as a touch screen for example), and the indication lamps 209, the fingerprint recognition area 211 and the touch sensing area 212 are optional. In this embodiment, Figure 3 is illustrated for easy understanding of the technical solutions of this invention.

    [0039] Further, the body of the remote exposure control device 20 is provided with a control circuit 213 for the remote exposure control device.

    [0040] As shown in Figure 3, in this embodiment, the control circuit for the remote exposure control device includes a power source module 2131, a sensing module 2133 electrically connected to the power source module 2131, a processing module 2135 electrically connected to the power source module 2131, and a communication module 2137 (such as a Bluetooth module, a radio frequency module, a WIFI module, an NFC module or the like). In fact, the power source module 2131 is electrically connected to all modules of the control circuit 213 so as to provide power thereto.

    [0041] The sensing module 2133 and the communication module 2137 are electrically connected to the processing module 2135 respectively, and may communicate with one another.

    [0042] The communication module 2137 is configured to communicate with the FPD 30, which is located in the digital radiography system and paired with the remote exposure control device.

    [0043] In this embodiment, the processing module 2135 is configured to, after receiving a trigger signal, generate a control instruction and control the communication module 2137 to send the control instruction to the FPD 30 so as to change a working state of the FPD 30.

    [0044] Specifically, the processing module 2135 is configured to, after receiving the trigger signal sent by the sensing module 2133, control the communication module 2137 to send the control instruction to the FPD 30, so that a communication module 301 provided on the FPD 30 receives the control instruction for changing a working state of the FPD 30. For example, the FPD 30 is awakened from a sleeping state or a power-off state to an exposure stand-by state (for example, the FPD 30 enters an AED mode).

    [0045] Those skilled in the art can understand the power-off state, the sleeping state and the exposure stand-by state of the pairing device, which will not be described herein. In this embodiment, three examples are given below to explain how the sensing module 2133 generates the trigger signal.
    1. 1) The sensing module 2133 includes a touch sensor 21331, which may include a capacitive touch sensor and/or a fingerprint recognition sensor. When the touch sensor 21331 is a capacitive touch sensor, it is configured to recognize a gesture instruction of a user and generate the trigger signal. The touch sensor 21331 may cooperate with the touch sensing area 212 which is of a mechanical structure to sense gesture operations.
    2. 2) When the touch sensor 21331 is a fingerprint recognition sensor, it is configured to generate the trigger signal after a matching fingerprint is recognized, so that only specific persons can operate the digital radiography system. The fingerprint recognition sensor may cooperate with the fingerprint recognition area 211 which is of a mechanical structure to sense touch operations and collect fingerprints.
    3. 3) The sensing module 2133 includes an acceleration sensor 21333 configured to generate the trigger signal after sensing movement of the remote exposure control device. For example, when the remote exposure control device is picked up or swung, the acceleration sensor 21333 can generate the trigger signal, enhancing the convenience of using the remote exposure control device.


    [0046] It should be noted that, in this embodiment, the touch sensor 21331 and the acceleration sensor 21333 may be provided in the sensing module 2133 separately or simultaneously. In this case, the sensing module 2133 may use the touch sensor 21331 or the acceleration sensor 21333 to generate the trigger signal. Of course, the trigger signal may be generated when the touch sensor 21331 receives a touch operation and the acceleration sensor 21333 senses movement of the remote exposure control device.

    [0047] In this embodiment, the remote exposure control device 20 may be configured to switch the FPD 30 from the exposure stand-by state to the sleeping state or the power-off state. Specifically, the processing module 2135 is configured to, if the trigger signal is not received within a predetermined period, control the communication module 2137 to send a sleeping or power-off instruction to the FPD 30, so that the communication module 301 provided on the FPD 30 receives the sleeping or power-off instruction for switching the FPD 30 from the exposure stand-by state to the sleeping state or the power-off state.

    [0048] Further, the sensing module 2133 may also include a camera 21335 configured to acquire identification information of one or more devices (the X-ray source 10, the FPD 30, the console 40, etc.) of the digital radiography system through scanning, such that the processing module 2135 pairs the remote exposure control device 20 with the one or more devices (the X-ray source 10, the FPD 30, the console 40, etc.) of the digital radiography system. The identification information of the one or more devices of the digital radiography system may be acquired by scanning a barcode/barcodes corresponding to the one or more devices of the digital radiography system.

    [0049] Preferably, the camera 21335 may be also configured to collect human images, so that the processing module 2135 can perform identification verification to users through the human images. After the verification succeeds, the users may be allowed to use the remote exposure control device 20.

    [0050] Further, the sensing module 2133 may also include a temperature sensor 21337 and/or a humidity sensor 21339. An example will be described below in which the sensing module 2133 includes a temperature sensor 21337 and a humidity sensor 21339. The temperature sensor 21337 may be configured to detect an ambient temperature of the remote exposure control device 20, and the humidity sensor 21339 an ambient humidity of the remote exposure control device 20. If a detected ambient temperature and/or ambient humidity of the remote exposure control device 20 exceeds a preset safe range, the remote exposure control device 20 sends a visible alarm and/or an acoustic alarm, and stops exposing.

    [0051] Those skilled in the art should understand that the touch sensor, the acceleration sensor, the camera, the temperature sensor and the humidity sensor may be integrally provided and communicate with the processing module 2135 via a bus; that these members may be provided separately and communicate with the processing module 2135 via multiple buses respectively; that these members may be integrated with other elements or circuits; and that for easy descriptions, these members are provided in the sensing module 2133 in this invention.

    [0052] Further, the control circuit for the remote exposure control device 20 further includes an audio module 2139 electrically connected to the processing module 2135 and comprising at least one of an audio processing chip 21391, a microphone 21393 and a speaker 21395. The speaker 21395 may be configured to send alarms. In this embodiment, the audio module 2139 includes both the microphone 21393 and the speaker 21395. Thus, voice communication with patients can be realized through the audio module 2139 of the remote exposure control device 20.

    [0053] Further, the control circuit for the remote exposure control device 20 further includes an input module 2141 electrically connected to the processing module 2135 and configured to input configuration information for the FPD 30, wherein the processing module 2135 is configured to control the communication module 2137 to send the configuration information to the FPD 30, so that the communication module 301 of the FPD 30 receives the configuration information and configures the parameters for the FPD 30. The input module 2141 may cooperate with the input keyboard which is of a mechanical structure, so that the remote exposure control device 20 can receive configuration information input by users.

    [0054] Further, the control circuit for the remote exposure control device 20 further includes an output module 2143 configured to output state information (for example, information indicating a remaining power amount of the FPD 30 and information indicating whether the FPD 30 is ready) of the FPD 30 received by the communication module 2137 of the remote exposure control device. Of course, the output module 2143 may be also configured to output the configuration information when the configuration information is input. In an embodiment of this invention, the state information and the configuration information are output visibly. The output module 2143 includes a display unit 21431 which may cooperate with a display screen 207 which is of a mechanical structure, so that the remote exposure control device 20 can output the state information. In an example, the output module 2143 further includes indication lamps 21433, which may act as another form of visible output for outputting the state information (for example, when the FPD is ready, an indication lamp is turned on). The indication lamps 21433 may also visibly output the alarms.

    [0055] As shown in Figure 4, in an embodiment of this invention, an exposing method for a digital radiography system comprises: sending a control instruction to a pairing device that is already paired, after sensing a preset operation by a remote exposure control device; receiving by the pairing device the control instruction, and switching a working state of the pairing device to an exposure stand-by state (for example, the FPD 30 enters an AED mode); and controlling the digital radiography system by the remote exposure control device to complete exposing.

    [0056] Exposing by the X-ray source under the control of the remote exposure control device may be performed through a two-stage switch of the remote exposure control device 20. Specifically, by pressing a first-stage switch, the high voltage generator of the X-ray source is pre-rotated. Then, a second-stage switch is pressed automatically or manually to complete exposing.

    [0057] It can be understood that, in this embodiment, after the working state of the FPD is switched to the exposure-standby state, the first-stage switch is pressed; or the first-stage switch is pressed before the working state of the FPD is switched to the exposure-standby state; and alternatively, of course, the first-stage switch is pressed while the working state of the FPD is switched to the exposure-standby state.

    [0058] Further, in this embodiment, three examples are given to describe the step of "sending a control instruction to a pairing device that is already paired, after sensing a preset operation by a remote exposure control device".
    1. 1) The preset operation is a touch operation indicating a predetermined gesture instruction input in a designated area of the remote exposure control device. That is, the sensing module 2133 senses a gesture operation by a finger on the touch sensing area 212. When a gesture operation on the touch sensing area 212 is sensed, the remote exposure control device 20 sends the control instruction to the paired FPD.
    2. 2) A designated area of the remote exposure control device receives fingerprint information. If the fingerprint information matches with pre-stored fingerprint information, it is determined that the remote exposure control device senses the preset operation. That is, the sensing module 2133 senses a touch operation by a finger on the fingerprint recognition area 211 to collect fingerprints. When a matching fingerprint is recognized, the remote exposure control device 20 sends the control instruction to the paired FPD.
    3. 3) The preset operation is a change of a position of the remote exposure control device. That is, if the acceleration sensor 21333 senses a movement of the remote exposure control device (for example, when the remote exposure control device is picked up or swung), the remote exposure control device 20 sends the control instruction to the paired FPD.


    [0059] It should be noted that the above methods may be used in succession in this embodiment to send an awaking or power-on instruction to the paired FPD. For example, if the fingerprint information matches with pre-stored fingerprint information, and movement of the remote exposure control device 20 is sensed, the remote exposure control device 20 sends the control instruction to the paired FPD.

    [0060] The exposing method for a digital radiography system further comprises: if the remote exposure control device does not sense the preset operation within a predetermined period, sending a sleeping or power-off instruction by the remote exposure control device to the paired FPD; after receiving the sleeping or power-off instruction by the paired FPD, switching the working state of the paired FPD to a sleeping or power-off state. The sleeping or power-off instruction is a type of a control instruction.

    [0061] Switching the working state to the sleeping or power-off state may be performed by the sensing module, the processing module and the communication module.

    [0062] Before sending the control instruction to the paired FPD, the method further comprises: pairing the remote exposure control device with the FPD so that the remote exposure control device and the FPD is capable of wirelessly communicating with each other. In this embodiment, the camera 21335 may acquire the identification information of the FPD 30 by scanning, so that the processing module 2135 pairs the remote exposure control device 20 with the FPD 30. The identification information of the FPD 30 may be acquired by scanning a barcode/two-dimensional code corresponding to the FPD 30.

    [0063] Before pairing the remote exposure control device with the FPD, the method may further comprise: collecting human images using the camera 21335 so as to perform identification verification to users through the human images. After the verification succeeds, the users may be allowed to use the remote exposure control device 20.

    [0064] The method further comprises: detecting an ambient temperature and/or an ambient humidity of the remote exposure control device; and if a detected ambient temperature and/or ambient humidity exceeds a preset safe range, sending by the remote exposure control device a visible alarm and/or an acoustic alarm, and stopping exposing.

    [0065] The visible alarm may be output by the output module 2143, and the acoustic alarm by the audio module 2139.

    [0066] After switching the working state of the FPD to the exposure stand-by state by the FPD, the method further comprises: receiving configuration information for the FPD by the remote exposure control device, and sending the configuration information to the FPD by the remote exposure control device; and receiving the configuration information by the FPD, and configuring parameters of the FPD by the FPD.

    [0067] Inputting the configuration information into the remote exposure control device may be performed by the input module 2141.

    [0068] The method further comprises: receiving state information(for example, information indicating a remaining power amount of the FPD and information indicating whether the FPD is ready) of the FPD by the remote exposure control device through radio frequency, and visibly outputting the state information. Outputting visible information may be performed by the output module 2143.

    [0069] It should be noted that the exposing method of this embodiment is realized by the above X-ray imaging system. The hardware solutions corresponding to the exposing method, and the functional features of the respective modules of the hardware are described in Figures 2-3 and the corresponding descriptions, and will not be repeated herein.

    [0070] As shown in Figure 5, the second embodiment differs from the first one in that the remote exposure control device 20 can wirelessly communicate with both the FPD 30 and the X-ray source.

    [0071] To sum up, the remote exposure control device of this invention simplifies the components of a digital radiography system and the connection among the components. In addition, the remote exposure control device of this invention can remotely interact with a pairing device paired therewith and remotely control the pairing device, realizing sciagraphing by one key and improving the work efficiency of users.

    [0072] It should be noted that the above embodiments are only intended to illustrate rather than limit the technical solutions of this invention. Although specific embodiments of this invention are described in detail through the above embodiments, those skilled in the art shall understand that modifications of the technical solutions or equivalent substitutions of some technical features of the above embodiments can be made without departing from the scope of the invention.
