[0072] The following discussion Figures 1 to 27 The various embodiments used to describe the principles of this disclosure in this patent document are merely exemplary and should not be construed in any way as limiting the scope of this disclosure. Those skilled in the art will understand that the principles of this disclosure can be implemented in any suitably arranged system or device.

[0073] The X-ray input device and its control method according to the present disclosure will be described in detail below with reference to the accompanying drawings.

[0074] The X-ray input device according to this disclosure can be carried by an operator, and the operator can use the X-ray input device wirelessly to control the X-ray imaging device.

[0075] In the following text, for ease of description, the configuration of the X-ray imaging apparatus on which this disclosure is based will be briefly described, and then the X-ray input apparatus according to this disclosure will be described.

[0076] Figure 1 The appearance of a conventional X-ray imaging device 10 is shown, and Figure 2 The appearance of the mobile X-ray imaging device 100 is shown.

[0077] like Figure 1As shown, in a typical X-ray imaging apparatus 10, the X-ray source 11 and the X-ray detector 13 can be fixed in a predetermined space. The X-ray source 11 can be connected to an arm 12 mounted on the ceiling of the examination room, and the X-ray detector 13 can be connected to a housing 15 fixed to the floor of the examination room.

[0078] The arm 12 connected to the X-ray source 11 can extend vertically to move the X-ray source 11 vertically relative to the floor. The X-ray detector 13 can also move vertically along the housing 15. That is, in a typical X-ray imaging apparatus 10, the X-ray source 11 and the X-ray detector 13 can move only within a predetermined space and in a predetermined direction.

[0079] refer to Figure 2 In the mobile X-ray imaging apparatus 100, the X-ray source 140 and the X-ray detector 400 can move freely in any three-dimensional (3D) space. More specifically, the X-ray source 140 can be mounted in the movable body 112 via a support arm 111a, and the support arm 111a can be rotatably connected to a support frame 111b. The support frame 111b can be rotatably connected to one side of the body 112. As a result, the support arm 111a can be rotatable, and therefore, the angle of the support arm 111a can be changed, allowing the X-ray source 140 to move freely. Furthermore, the X-ray detector 400 of the mobile X-ray imaging apparatus 100 can be a portable X-ray detector, and therefore, the X-ray detector 400 can also be located at any position in 3D space.

[0080] On one side of the main body 112, a holder 104 can be configured to receive the X-ray input device 120. When the operator is not using the X-ray input device 120, the operator can place the X-ray input device 120 in the holder 104 to hold the X-ray input device 120. When the operator uses the X-ray input device 120, the operator can remove the X-ray input device 120 from the holder 104 to use the X-ray input device 120.

[0081] The structure of the X-ray input device 120 will be described below, followed by a detailed description of the operation of the X-ray input device 120 and the X-ray imaging device 100.

[0082] Figure 3 A control block diagram of an X-ray input device according to an embodiment is shown. Figure 4 The structure of the X-ray input device according to an embodiment is shown. Figure 5 An example of the gripping area of ​​the X-ray input device is shown, and Figure 6 This illustrates the situation when the X-ray input device is housed in the retainer. Figure 4 X-ray input device.

[0083] refer to Figure 3The X-ray input device 120 may include a position sensor 123a for detecting the position of the X-ray input device 120, a touch sensor 126 for sensing touch, a radiation button 124 for receiving X-ray radiation commands, an input controller 121 for controlling the operation of the X-ray input device 120, and an input communication device 127 for sending / receiving signals through communication with the holder 104.

[0084] refer to Figure 3 , Figure 4 and Figure 5 The X-ray input device 120 may include a body 122 that can be housed in a retainer 104, and a gripping area 125 formed on the outer peripheral surface of the body 122, wherein a radiation button 124 may be disposed on the top of the body 122.

[0085] The gripping area 125 can be gripped by a user using the X-ray input device 120, particularly a user operating the radiation button 124 while carrying the X-ray input device 120. For example, the gripping area 125 can be located in the central region of the body 122 in the z-axis direction, or the gripping area 125 can be located adjacent to the radiation button 124.

[0086] The touch sensor 126 can be driven capacitively.

[0087] The touch sensor 126 may be disposed along the outer circumferential surface of the gripping area 125. The touch sensor 126 may be in the form of a touch sensor surrounding the outer circumferential surface of the body 122, or it may be in the form of multiple touch sensors arranged at regular intervals.

[0088] The touch sensor 126 can be located anywhere, as long as the operator's hand can touch the touch sensor 126 when the operator grasps the X-ray input device 120.

[0089] If the touch sensor 126 is located on the gripping area 125, as described above, the touch sensor 126 can sense the operator's touch when the operator grips the body 122. If the touch sensor 126 senses the operator's touch, the X-ray input device 120 can determine that the operator has gripped the X-ray input device 120.

[0090] In addition, such as Figure 5 As shown, an engraved pattern H in the shape of a finger can be formed in the gripping area 125 to allow the operator to easily grip the X-ray input device 120. Furthermore, the engraved pattern H can guide the operator to grip the X-ray input device 120 in the appropriate position.

[0091] The touch sensor 126 may be formed in the remaining area of ​​the gripping area 125 excluding the printed pattern H, or it may be formed in a predetermined area of ​​the gripping area 125 including the printed pattern H. When the touch sensor 126 is formed in the remaining area of ​​the gripping area 125 excluding the printed pattern H, the touch sensor 126 may be formed in the rear surface of the gripping area 125 opposite to the printed pattern H.

[0092] If the touch sensor 126 is formed in the rear surface of the gripping area 125 opposite to the printed pattern H, the touch sensor 126 can immediately collect touch input information when the operator grips the X-ray input device 120, thereby improving the input accuracy of X-ray radiation commands and calibration control commands.

[0093] However, the touch sensor 126 does not necessarily have to be located in the rear surface of the gripping area 125 opposite to the printed pattern H. That is, the touch sensor 126 can be located in any area touched by the operator's hand when the operator grips the X-ray input device 120 on the printed pattern H, and the positional relationship between the printed pattern H and the touch sensor 126 is not limited thereto.

[0094] refer to Figure 6 The position sensor 123a can be disposed in a region of the body 122 to collect information about whether the X-ray input device 120 is housed in the retainer 104.

[0095] For example, position sensor 123a may be disposed in the lower region of the body 122 of X-ray input device 120. However, the position of position sensor 123a is not limited to this, and position sensor 123a may be located in any position where position sensor 123a can sense whether X-ray input device 120 is housed in holder 104.

[0096] Position sensor 123a may include at least one of a magnetic field sensor, a limit switch, an optical sensor, and an ultrasonic sensor. For example, if position sensor 123a includes a magnetic field sensor, a magnet may be disposed in the area of ​​holder 104 corresponding to position sensor 123a.

[0097] Furthermore, if the position sensor 123a includes an optical sensor or an ultrasonic sensor, then the position sensor 123a may include a transmitter for emitting light (e.g., infrared light or visible light) or ultrasonic waves, and a receiver for receiving light or ultrasonic waves reflected from the inner wall of the retainer 104. Additionally, the X-ray input device 120 may include a receiver, and the transmitter may be mounted in the retainer 104. However, the types of position sensors 123a are not limited to the examples described above.

[0098] Depending on the type of position sensor 123a, a reference value indicating that the body 122 is housed in the holder 104 can be pre-stored. The reference value may have already been stored as a predetermined reference range.

[0099] The input controller 121 can compare the output of the position sensor 123a with a reference value to determine whether the body 122 is housed in the retainer 104.

[0100] Figures 7 to 9 A view is shown illustrating the operation of an X-ray input device receiving control commands from an operator.

[0101] refer to Figure 7 The radiation button 124 may be located on the top of the main body 122. The radiation button 124 may be in the form of a two-step switch protruding from the top of the main body 122. The radiation button 124 may include a one-step button 124a for receiving a ready command and a two-step button 124b for receiving a radiation command.

[0102] Ready commands and radiation commands input via radiation button 124 can be used together with touch information input to touch sensor 126 or position information collected from position sensor 123a to determine control commands for X-ray input device 120 or X-ray imaging device 100.

[0103] An operator can grip the X-ray input device 120 on the gripping area 125. For example, the operator can grip the gripping area 125 with four fingers, excluding the thumb. When the operator grips the gripping area 125, the operator's hand can touch the touch sensor 126 located on the gripping area 125, thus the touch sensor 126 can sense the operator's touch. In this state, the operator can press the radiation button 124 protruding from the top of the main body 122 to input control commands.

[0104] like Figure 8 As shown, if the operator presses the radiation button 124 to set the ready state when the touch sensor 126 senses the operator's touch, a ready command instructing the operator to preheat for irradiating X-rays can be entered. For example, the operator can apply pressure within the range of a first threshold pressure to a second threshold pressure on the one-step button 124a used to receive the ready command to enter a first command. The first command could be an X-ray radiation preparation command. In this example, all or part of the one-step button 124a can be inserted inside the two-step button 124b.

[0105] Then, as Figure 9As shown, if the touch sensor 126 senses the operator's touch and presses the radiation button 124 to set the ready state, and the operator further applies pressure to the radiation button 124 to set the radiation state, a radiation command for actual X-ray radiation can be input. For example, the operator can apply pressure higher than or equal to a second threshold pressure to the radiation button 124 to input a second command, which can be an X-ray radiation command. In this example, all or part of the two-step button 124b can be inserted into the interior of the body 122.

[0106] The first threshold pressure can be equal to or lower than the second threshold pressure. That is, after inserting the one-step button 124a into the two-step button 124b to input the X-ray radiation preparation command, the same pressure can be applied to input the X-ray radiation command, or a higher pressure can be applied to input the X-ray radiation command than when inputting the X-ray radiation preparation command.

[0107] In various embodiments, the X-ray radiation command can be entered after the X-ray radiation preparation command is entered. That is, X-rays can be irradiated after the X-ray radiation preparation command is entered.

[0108] The calibration control of touch sensor 126 will be described below.

[0109] Figure 10 A graph is shown illustrating the capacitance threshold set by the calibration control of the X-ray imaging apparatus according to an embodiment.

[0110] Calibration control of the touch sensor 126 can be performed to determine the capacitance threshold of the touch sensor 126 based on a capacitance threshold reference value. The capacitance reference value can be a capacitance value measured when there is no external touch on the touch sensor 126, and the capacitance threshold can be a capacitance value based on which a capacitance change caused by an external stimulus is identified as a touch stimulus from the operator. That is, when there is no external touch on the touch sensor 126, a capacitance value exceeding the capacitance threshold can be measured, and when an external touch is performed on the touch sensor 126, a capacitance value equal to or less than the capacitance threshold can be measured.

[0111] Because the capacitance reference value of touch sensor 126 depends on the surrounding environment, such as temperature and humidity, the touch sensitivity of touch sensor 126 can also depend on the surrounding environment. Therefore, the capacitance threshold of touch sensor 126 can be changed through calibration control of touch sensor 126. The process of resetting the capacitance threshold based on the changed capacitance reference value of touch sensor 126 is called calibration control of touch sensor 126.

[0112] like Figure 10As shown in the graph, the input controller 121 can receive the output value of the touch sensor 126 and use the output value of the touch sensor 126 as the capacitance reference value C1. The output value of the touch sensor 126 used as the capacitance reference value C1 can be a value measured when calibration control is performed, or a value measured when a calibration control command is input. Alternatively, the output value of the touch sensor 126 used as the capacitance reference value C1 can be a value measured at any time between inputting a calibration control command and performing calibration control.

[0113] The minimum value D of the capacitance change that may be caused by touch may have been pre-stored, and the input controller 121 may determine the capacitance threshold T1 based on the capacitance reference value C1 and the minimum capacitance change D. For example, the input controller 121 may determine the capacitance threshold T1 by subtracting the minimum capacitance change D from the capacitance reference value C1.

[0114] If the calibration is performed correctly according to the above procedure, the capacitance threshold T1 can be determined as the capacitance reference value C1 and the minimum capacitance value C caused by the operator's touch. min The values ​​between.

[0115] The method by which the operator inputs calibration control commands will be described below.

[0116] Refer again Figure 6 When the X-ray input device 120 is housed in the holder 104, the X-ray input device 120 according to the embodiment can perform calibration control. Therefore, when the output from the position sensor 123a indicates that the X-ray input device 120 is housed in the holder 104, the input controller 121 can perform calibration control.

[0117] As described above, the input controller 121 may have stored a reference value indicating that the X-ray input device 120 is housed in the retainer 104. If the output of the position sensor 123a is the same as the reference value, the input controller 121 can determine that the X-ray input device 120 is housed in the retainer 104.

[0118] Simultaneously, if calibration control is performed when a touch is made on the touch sensor 126, a smaller capacitance reference value C1 can be measured than when there is no touch on the touch sensor 126. As a result, a calibration error can occur, causing a capacitance threshold T1 to be determined that is smaller than when there is no touch on the touch sensor 126. In one or more embodiments, the capacitance threshold T1 can be less than the minimum capacitance value C. min .

[0119] However, similar to the embodiments described above, if calibration control is performed only when the X-ray input device 120 is housed in the holder 104, it is possible to prevent the capacitance threshold from being set to an abnormally small value due to calibration errors. Therefore, compared to when calibration control is performed, the input accuracy of the calibration control command can be improved regardless of whether the X-ray input device 120 is housed in the holder 104.

[0120] Furthermore, the accuracy of calibration control can be improved by additionally using the output of touch sensor 126 to determine whether calibration control should be performed. In this example, input controller 121 can perform calibration control when X-ray input device 120 is housed in holder 104 and the output of touch sensor 126 exceeds a capacitance threshold.

[0121] Figure 11 A view is shown illustrating another example of an X-ray input device receiving calibration control commands according to an embodiment.

[0122] refer to Figure 11 For example, when the X-ray input device 120 is housed in the retainer 104, the operator can press the radiation button 124 to input calibration control commands.

[0123] More specifically, if an operator presses the radiation button 124 without touching the touch sensor 126 to set the ready state when the X-ray input device 120 is housed in the holder 104, it can be determined that a calibration control command has been entered and calibration control can be executed.

[0124] When a pressure higher than or equal to a first threshold pressure and lower than a second threshold pressure is applied to the radiation button 124 to input a first command, the radiation button 124 can transmit a first signal to the input controller 121. The first signal may be a signal indicating that the radiation button 124 has been pressed to set a ready state, or a signal indicating that a pressure between the first threshold pressure and the second threshold pressure has been applied.

[0125] Furthermore, when a pressure equal to or higher than the second threshold pressure is applied to the radiation button 124 to input a second command, the radiation button 124 can transmit a second signal to the input controller 121. The second signal may be a signal indicating that the radiation button 124 has been pressed to set the radiation state, or a signal indicating that a pressure between the second threshold pressure and the third threshold pressure has been applied.

[0126] When the output of position sensor 123a indicates that X-ray input device 120 is housed in holder 104 and a first signal has been input from radiation button 124, input controller 121 can determine that a calibration control command has been input.

[0127] Additionally, the input controller 121 can further determine whether the output of the touch sensor 126 exceeds the capacitance threshold, i.e., whether the touch sensor 126 has not received touch input. When the touch sensor 126 does not receive touch input, the input controller 121 can determine that a calibration control command has been input.

[0128] If pressing the radiation button 124 of the X-ray input device 120 housed in the retainer 104 is to input a calibration control command, as in the current example, it can more clearly reflect the user's intent, thereby reducing unnecessary calibration.

[0129] If the input controller 121 determines that a calibration control command has been input, the input controller 121 can perform calibration control according to the above operation.

[0130] Furthermore, when the output value of the touch sensor 126 is equal to or less than the capacitance threshold, the input controller 121 can determine whether an X-ray radiation preparation command or an X-ray radiation command has been input based on the signal output from the radiation button 124.

[0131] More specifically, when the output value of the touch sensor 126 is equal to or less than the capacitance threshold, if a first signal is output from the radiation button 124, the input controller 121 can determine that an X-ray radiation preparation command has been input, and if a second signal is output from the radiation button 124, an X-ray radiation command is input.

[0132] Additionally, the input controller 121 can use the output from the position sensor 123a. When the output of the position sensor 123a indicates that the X-ray input device 120 is not housed in the holder 104, the input controller 121 can determine that an X-ray radiation preparation command or an X-ray radiation command has been input.

[0133] When an X-ray radiation preparation command is input, the input controller 121 can send an X-ray radiation preparation signal to the holder 104 through the input communication device 127, and when an X-ray radiation command is input, the input controller 121 can send an X-ray radiation signal to the holder 104 through the input communication device 127.

[0134] Figure 12 A control block diagram of an X-ray input device according to another embodiment is shown. Figure 13 It shows Figure 12 The appearance of the X-ray input device shown, and Figure 14 A control block diagram is shown that further includes an X-ray input device with a position sensor.

[0135] refer to Figure 12 and Figure 13According to another embodiment, the X-ray input device 220 may include an environmental sensor 223b for acquiring information about the surrounding environment, a touch sensor 226, a radiation button 224, an input controller 221, and an input communication device 227. The environmental sensor 223b may be disposed in the area of ​​the main body 222 of the X-ray input device 220.

[0136] When the ambient environmental information acquired by the environmental sensor 223b meets the calibration conditions, the input controller 221 can automatically perform calibration control. Calibration control has already been described above in the embodiment of the X-ray input device 120.

[0137] The environmental sensor 223b may include at least one of a temperature sensor and a humidity sensor. Therefore, the ambient environmental information acquired by the environmental sensor 223b may include temperature information or humidity information.

[0138] The environmental sensor 223b can sense surrounding environmental information in real time or at predetermined time intervals and transmit the sensed surrounding environmental information to the input controller 221.

[0139] The input controller 221 can determine whether to perform calibration control based on the output of the environmental sensor 223b. More specifically, the input controller 221 can perform calibration control when the ambient environmental information received from the environmental sensor 223b meets the calibration conditions.

[0140] For example, when temperature or humidity information included in the ambient environment information is outside the reference range, the controller 121 can determine that the calibration conditions are met. The reference range can be set to a range of given values, or it can be reset each time calibration is performed.

[0141] When the temperature or humidity information is within the reference range, it can be assumed that the X-ray input device 220 is used in a constant temperature and humidity environment. If the environment cannot be maintained, calibration control can be performed to reset the capacitance threshold. Furthermore, even after calibration control is performed, ambient environmental information can be collected periodically, and if the collected temperature or humidity is outside the reference range, calibration control can be performed again to reset the changed capacitance threshold.

[0142] When the temperature or humidity information is outside the reference range, the temperature or humidity information at the time of calibration control can be stored whenever the input controller 121 performs calibration control, and the reference range can be reset based on the stored temperature or humidity information. If the ambient environment information measured after calibration control differs from the stored ambient environment information by a reference value or greater, it can be determined that the calibration conditions are met. In this case, calibration control can be performed again to reset the capacitance threshold. The temperature or humidity information measured when calibration control is performed again can also be stored.

[0143] According to the current embodiment, by performing calibration control only when calibration control is required due to changes in the surrounding environment, any unnecessary operation can be prevented.

[0144] Apart from determining whether to perform calibration control based on the output of the environmental sensor 223b, the operation of the touch sensor 226 provided on the grip area 225 to sense the operator's touch, the operation of the radiation button 224 provided on the top of the main body 222 to receive ready commands and radiation commands, and the related operation of the input controller 221 can be the same as the corresponding operation of the X-ray input device 120 according to the above embodiment, therefore, their detailed description will be omitted.

[0145] At the same time, such as Figure 14 As shown, according to another embodiment, the X-ray input device 220 may further include a position sensor 223a for sensing whether the X-ray input device 220 is housed in the holder 104.

[0146] Similar to position sensor 123a according to the above embodiment, position sensor 223a may include at least one of a magnetic field sensor, a limit switch, an optical sensor, and an ultrasonic sensor. Furthermore, the above description of position sensor 123a can be applied to position sensor 223a according to the current embodiment.

[0147] Input controller 221 can determine whether X-ray input device 220 is housed in retainer 104 based on the output of position sensor 223a. If input controller 221 determines that X-ray input device 220 is housed in retainer 104, input controller 221 can determine whether to perform calibration control based on ambient information received from ambient sensor 223b. That is, input controller 221 can perform calibration control when X-ray input device 120 is already housed in retainer 104 and ambient information is outside the reference range.

[0148] Furthermore, it can be determined first whether the surrounding environmental information is outside the reference range, or it can be determined simultaneously whether the surrounding environmental information is outside the reference range and whether the X-ray input device 120 is already housed in the holder 104. In other words, it can be determined whether the X-ray input device 120 is already housed in the holder 104 and whether the surrounding environmental information is outside the reference range, and the order of determination is not limited.

[0149] Furthermore, by including conditions where no operator touches the X-ray input device 220 under calibration control conditions, the accuracy of calibration control can be improved. The input controller 121 can perform calibration control when the output of the environmental sensor 223b exceeds the reference range and the output of the touch sensor 226 exceeds the capacitance threshold.

[0150] The above has been referenced Figure 12 and Figure 13 The operation of input controller 121 determining whether to perform calibration control based on surrounding environmental information is described.

[0151] According to the current embodiment, calibration control can be performed as needed based on the conditions under which the X-ray input device 220 is housed in the holder 104 and the environmental changes in the calibration control conditions. Furthermore, calibration control can be omitted when the operator is using the X-ray input device 220, thereby improving the accuracy of calibration control.

[0152] Figure 15 A control block diagram of an X-ray input device according to yet another embodiment is shown. Figure 16 It shows Figure 15 The appearance of the X-ray input device, and Figure 17 A view is shown illustrating the operation of an X-ray input device receiving calibration control commands according to yet another embodiment.

[0153] refer to Figure 15 and Figure 16 According to another embodiment, the X-ray input device 320 may include a touch sensor 326, a radiation button 324, an input controller 321, an input communication device 327, and a calibration button 329 disposed on the upper region of the outer circumferential surface of the main body 322.

[0154] The calibration button 329 can be implemented as a button protruding from the surface of the body 322, or as a touch switch.

[0155] like Figure 17 As shown, the operator can input calibration commands by pressing the calibration button 329 and the radiation button 324 simultaneously.

[0156] If the calibration button 329 is touched or pressed, the calibration button 329 can generate a third signal and transmit the third signal to the input controller 321. The third signal can be a signal indicating that the operator's input has been received, that is, a signal indicating that the calibration button 329 has been touched or pressed.

[0157] If the input controller 321 receives a third signal from the calibration button 329 and a first signal from the radiation button 324, the input controller 321 can determine that a calibration command has been input and execute calibration control. That is, according to the current embodiment, when the radiation button 324 and the calibration button 329 are pressed simultaneously, or when both the radiation button 324 and the calibration button 329 are touched simultaneously, the input controller 321 can determine that a calibration command has been input.

[0158] Accidental calibration can be prevented by performing calibration control when a combined input signal is received via the radiation button 324 and the calibration button 329. However, the function of the calibration button 329 is not limited to this, and the calibration button 329 can provide additional functions according to the designer's intent.

[0159] The operation of the X-ray imaging apparatus 100, which includes the X-ray input devices 120, 220 or 320 described above, will be described in detail below.

[0160] Figure 18 A control block diagram of an X-ray imaging apparatus according to an embodiment is shown.

[0161] refer to Figure 18 The X-ray imaging apparatus 100 may include: an input device 105 for receiving commands from an operator to control the X-ray imaging apparatus 100; a holder communication device 152 disposed inside a holder 104 and configured to receive data from the input device 105; a holder controller 151 for converting the data received from the input device 105 into control signals; a main controller 130 for controlling the overall operation of the X-ray imaging apparatus 100; an X-ray source 140 for generating and irradiating X-rays; and a high-voltage generator 160 for applying high-voltage energy to the X-ray source 140.

[0162] In addition, the X-ray source 140 may include an X-ray tube 141 and a collimator 144. The X-ray tube 141 is used to receive high-voltage energy generated by the high-voltage generator 160 and to generate and irradiate X-rays, and the collimator 144 is used to guide the path of the X-rays irradiated by the X-ray tube 141.

[0163] The operator can input commands for X-ray exposure via input device 105. Input device 105 may include at least one of a switch, keypad, trackball, or touchscreen, or may be provided in the form of a foot switch or foot pedal.

[0164] Furthermore, the input device 105 can be provided as a mobile X-ray input device, into which commands can be input when the operator grasps the input device 105 with their hand and presses a button with their thumb. The X-ray input device can be provided as a two-step switch. The X-ray input device can be X-ray input device 120, 220, or 320 according to the above embodiments.

[0165] As described above, when the output from at least one of the position sensor 123a or 223a, the environmental sensor 223b, the calibration button 329, the touch sensor 126, 226 or 326, and the radiation button 124, 224 or 324 indicates the input of a calibration control command or that calibration conditions are met, the input controller 121, 221 or 321 may perform calibration control based on the output of the touch sensor 126, 226 or 326.

[0166] When the output value of touch sensors 126, 226, or 326 is greater than or equal to the capacitance threshold T1, input controllers 121, 221, or 321 can determine that an X-ray radiation preparation command or an X-ray radiation command has been input based on the signal output from radiation buttons 124, 224, or 324. The operations performed when an X-ray radiation preparation command or an X-ray radiation command is input will be described below.

[0167] If the output of touch sensor 126, 226 or 326 is greater than or equal to the capacitance threshold T1, and a first signal or a second signal is received from radiation button 124, 224 or 324, then input controller 121, 221 or 321 can send an X-ray radiation preparation command or an X-ray radiation signal to holder communication device 152 through input communication device 127, 227 or 327.

[0168] Input communication devices 127, 227, or 327 can transmit signals generated by X-ray input devices 120, 220, or 320 to retainer 104 via wireless communication. Input communication device 127 may include at least one of a Wireless Local Area Network (WLAN) module and a Short Range Communication (SMR) module. In this disclosure, input communication devices 127, 227, or 327 may be either a WLAN module or a SMR module. However, when X-ray input devices 120, 220, or 320 are connected to retainer 104 in a wired manner, input communication devices 127, 227, or 327 may use wired Ethernet.

[0169] The WLAN module can support IEEE 1002.11x, the standard of the Institute of Electrical and Electronics Engineers (IEEE).

[0170] The short-range communication module can be a communication module that supports at least one of various wireless communication methods, such as Bluetooth, Bluetooth Low Energy, Zigbee communication, Infrared Data Association (IrDA), Wi-Fi, Wi-Fi Direct, Ultra Wideband (UWB), Near Field Communication (NFC), etc. However, the input communication devices 127, 227, or 327 are not limited to the examples described above, and other communication methods known to those skilled in the art can be used.

[0171] The holder controller 151 can transmit the X-ray radiation preparation signal or the X-ray radiation signal to the main controller 130.

[0172] Figure 18 An example is shown in which the X-ray input device 120, 220, or 320 transmits an X-ray radiation preparation signal or an X-ray radiation signal to the holder controller 151. However, according to some embodiments, the input controller 121, 221, or 321 may transmit the X-ray radiation preparation signal or the X-ray radiation signal directly to the main controller 130.

[0173] The main controller 130 may include at least one memory for storing programs for performing the operations described above and those to be described later, and at least one processor for running the stored programs. Furthermore, the processors included in the main controller 130 may be categorized according to the operations to be performed. For example, the processors may include a processor for controlling X-ray radiation components and a processor for processing image signals transmitted from the X-ray detector 400. When the main controller 130 includes multiple processors and multiple memories, the processors and memories may be integrated into a single chip or may be physically separate.

[0174] If the main controller 130 receives an X-ray radiation preparation signal from the holder controller 151, the main controller 130 can input the X-ray radiation preparation signal to the high voltage generator 160.

[0175] If the high voltage generator 160 receives an X-ray radiation preparation signal, the high voltage generator 160 can start preheating, and if preheating is complete, the high voltage generator 160 can output a ready signal to the main controller 130.

[0176] If the main controller 130 receives a ready signal from the high-voltage generator 160 and an X-ray radiation signal from the holder controller 151, then the main controller 130 can input the X-ray radiation signal to the high-voltage generator 160. If the high-voltage generator 160 receives the X-ray radiation signal from the main controller 130, then the high-voltage generator 160 can generate a high voltage and apply that high voltage to the X-ray tube 141. The X-ray tube 141 can generate and radiate X-rays. The X-rays radiated from the X-ray tube 141 and then passing through the collimator 144 can radiate onto the object.

[0177] X-rays radiated from X-ray tube 141 and then passing through collimator 144 can penetrate the object and are then radiated to X-ray detector 400. X-ray detector 400 can detect the radiated X-rays and convert the detected X-rays into electrical signals. The electrical signals converted from the X-rays passing through the object can be converted into X-ray image signals of the object.

[0178] The X-ray detector 400 may be a portable X-ray detector that can be carried by a user and can be wirelessly connected to the X-ray imaging device 100. The X-ray detector 400 may be included in the X-ray imaging device 100 as a component of the X-ray imaging device 100, or the X-ray detector 400 may be manufactured and sold separately from the X-ray imaging device 100.

[0179] The X-ray imaging apparatus 100 may further include a main communication device 170 for communicating with the X-ray detector 400. The main communication device 170 may be a communication module that supports at least one of various wireless communication methods, such as WLAN, Wi-Fi, Bluetooth, Zigbee, Wi-Fi Direct, UWB, IrDA, BLE, NFC, etc.

[0180] The X-ray detector 400 can send the X-ray image signal of the object to the main communication device 170, and the main communication device 170 can transmit the X-ray image signal to the main controller 130.

[0181] Simultaneously, if the main controller 130 receives an X-ray radiation readiness signal from the holder controller 151, the main controller 130 can send the X-ray radiation readiness signal to the X-ray detector 400 and the high-voltage generator 160 via the main communication device 170. If the X-ray detector 400 receives the X-ray radiation readiness signal, the X-ray detector 400 can prepare to detect X-rays. When the X-ray detector 400 is ready to detect X-rays, the X-ray detector 400 can send a ready signal to the main communication device 170. However, the operation of sending a ready signal to the main communication device 170 can be omitted.

[0182] If the main controller 130 receives a ready signal from the high-voltage generator 160 and the X-ray detector 400, and receives an X-ray radiation signal from the holder controller 151, then the main controller 130 can transmit the X-ray radiation signal to the high-voltage generator 160. As described above, if the high-voltage generator 160 receives the X-ray radiation signal, then the high-voltage generator 160 can apply high voltage to the X-ray source 140 to generate X-rays.

[0183] Figure 19 A control block diagram of a mobile device capable of performing the functions of an X-ray input device according to an embodiment is shown, and Figure 20 and Figure 21 An example of a screen that can be displayed on a mobile device is shown.

[0184] All or some of the operations performed by the X-ray input devices 120, 220 or 320 according to the above embodiments can be performed by mobile devices including touch screens, such as smartphones, tablet PCs and personal digital assistants (PDAs).

[0185] refer to Figure 19 The mobile device 500 may include a touch screen 520, a controller 510, and a communication device 530, and the touch screen 520 may include a display 521 and a touch panel 522 disposed on the front surface of the display 521.

[0186] The touchscreen 520 can perform the functions of a display device to provide visual information to the user, and the functions of an input device to receive commands from the user. The functions of the display device can be performed by the display 521, and the functions of the input device can be performed by the touch panel 522.

[0187] The controller 510 may include: at least one memory for storing a program for performing operations described later; and at least one processor for running the stored program.

[0188] The controller 510 can control the overall operation of the mobile device 500. Therefore, the operations performed by the communication device 530 and the touch screen 520 can be controlled by the controller 510, unless otherwise stated.

[0189] In the operations performed by the controller 510, operations that are the same as, similar to, or related to the operations of the X-ray input devices 120, 220, or 320 can be performed by running a relevant program or application installed on the mobile device 500. In the following embodiments, the relevant program or application is referred to as an X-ray radiation control program.

[0190] The X-ray radiation control program can control the touchscreen of the mobile device 500 to display an X-ray radiation preparation button for receiving X-ray radiation preparation commands and an X-ray radiation button for receiving X-ray radiation commands. The X-ray radiation control program can run an X-ray radiation control method that, if a touch is sensed on the area corresponding to the X-ray radiation preparation button, sends an X-ray radiation preparation signal to the X-ray imaging device 100; if a touch is sensed on the area corresponding to the X-ray radiation button, sends an X-ray radiation signal to the X-ray imaging device 100; and if a touch is sensed on the remaining area other than the areas corresponding to the X-ray radiation preparation button and the X-ray radiation button, neither an X-ray radiation preparation signal nor an X-ray radiation signal is sent.

[0191] The X-ray radiation control program can be an embedded application installed by default on the mobile device 500, or a third-party application received from an external recording medium.

[0192] When the mobile device 500 receives an X-ray radiation control program from an external recording medium, the mobile device 500 can download the X-ray radiation control program from an external server including a computer-readable recording medium, and install the X-ray radiation control program to store it in a memory included in a controller 510. This includes a processor in the controller 510 capable of running the stored program to execute the X-ray radiation control method. Embodiments of the X-ray radiation control method run by the mobile device 500 will be described in more detail later.

[0193] The communication device 530 may be a wireless communication module capable of performing wireless communication with external devices. For example, the wireless communication module may be at least one of a WLAN module and a short-range communication module. The short-range communication module may be a communication module that supports at least one of various wireless communication methods (such as Bluetooth, Bluetooth Low Energy, Zigbee communication, IrDA, Wi-Fi, Wi-Fi Direct, UWB, NFC, etc.).

[0194] When the mobile device 500 runs the X-ray radiation control program, the controller 510 can control the touchscreen 520 to display a ready button 520a for receiving X-ray radiation preparation commands and a radiation button 520b for receiving X-ray radiation commands, such as... Figure 20 As shown in the example.

[0195] Users can touch the Ready button 520a or the Radiation button 520b to enter an X-ray radiation preparation command or an X-ray radiation command.

[0196] The output of touch panel 522 can be transmitted to controller 510, and controller 510 can determine whether an X-ray radiation preparation command or an X-ray radiation command has been input based on the output of touch panel 522. Similar to the above embodiments of X-ray input devices 120, 220, or 320, when the output of touch panel 522 is less than or equal to a predetermined reference value, such as a capacitance threshold, controller 510 can determine that touch input has been received by touch panel 522.

[0197] When the touch panel 522 senses a touch on the area corresponding to the ready button 520a, that is, when an X-ray radiation preparation command is input, the controller 510 can control the communication device 530 to send an X-ray radiation preparation signal to the X-ray imaging apparatus 100. For example, if the communication device 530 includes a Bluetooth communication module, the controller 510 can convert the X-ray radiation preparation signal into Bluetooth packets and send the Bluetooth packets to the X-ray imaging apparatus 100.

[0198] Furthermore, when the touch panel 522 senses a touch on the area corresponding to the radiation button 520b, that is, when an X-ray radiation command is input, the controller 510 can control the communication device 530 to send the X-ray radiation command to the X-ray imaging device 100.

[0199] Simultaneously, if the touch panel 522 senses a touch on an area other than the area corresponding to the ready button 520a and the radiation button 520b, the controller 510 can determine that neither an X-ray radiation preparation command nor an X-ray radiation command is input. In this example, although the ready button 520a or the radiation button 520b is touched, the controller 510 may neither send an X-ray radiation preparation signal to the X-ray imaging device 100 nor an X-ray radiation signal to the X-ray imaging device 100. Therefore, when the touch screen 520 of the mobile device 500 receives an input made due to error when the user did not intend to input an X-ray radiation preparation command or an X-ray radiation command, the controller 510 can prevent the high-voltage generator 160 from being unnecessarily preheated or prevent X-ray radiation.

[0200] Furthermore, the controller 510 can perform calibration control on the touch panel 522. Calibration control has already been described above in embodiments of X-ray input devices 120, 220, or 320.

[0201] The controller 510 can determine the timing of calibration control based on the output value of the touch panel 522. For example, the output value of the touch panel 522 can increase or decrease uniformly across the entire area based on temperature changes. Therefore, the controller 510 can monitor the output value of the touch panel 522 in real time or periodically, and can perform calibration control when the output value of the touch panel 522 changes in a manner that generates a uniform increase or decrease across the entire area.

[0202] Alternatively, such as Figure 21 As shown, the touchscreen 520 can display a calibration button 520c for receiving calibration commands from the user.

[0203] In this example, when the touch panel 522 senses a touch on the area corresponding to the calibration button 520c, that is, when a calibration command is entered, the controller 510 can perform calibration control.

[0204] Alternatively, the controller 510 can determine the timing of calibration control based on ambient environmental information, similar to the above-described embodiment of the X-ray input device 220. Reference will be made below to... Figure 22 Describe the operation.

[0205] Figure 22 A control block diagram of a mobile device is shown, which determines calibration conditions based on changes in the surrounding environment.

[0206] refer to Figure 22 The mobile device 500 may further include an environmental sensor 540 for acquiring information about the surrounding environment.

[0207] The environmental sensor 540 can be at least one of a temperature sensor and a humidity sensor. Therefore, the ambient environmental information acquired by the environmental sensor 540 can include temperature information or humidity information.

[0208] The environmental sensor 540 can sense the surrounding environment information in real time or periodically and transmit the sensed surrounding environment information to the controller 510.

[0209] If the controller 510 determines that the ambient information received from the environmental sensor 223b meets the calibration conditions, the controller 510 can perform calibration control. For example, if the temperature or humidity information included in the ambient information is outside a predetermined reference range, the controller 510 can determine that the calibration conditions are met. The reference range can be set to a range of given values, or the reference range can be reset each time calibration is performed.

[0210] The following describes a method for controlling an X-ray input device 100 according to one aspect. The above embodiments of X-ray input devices 120, 220, and 320 can be applied to the method of controlling the X-ray input device 100. Therefore, unless otherwise stated, the above references are... Figures 1 to 22 The given description can be applied to a method of controlling an X-ray input device 100 according to an embodiment described below.

[0211] Figure 23 and Figure 24 This is a flowchart illustrating a method for controlling an X-ray input device according to an embodiment, and the X-ray input device 120 according to the above embodiment can be applied to the method for controlling an X-ray input device 100 according to the present embodiment.

[0212] According to the method of controlling the X-ray input device 100, such as Figure 23 As shown, in operation 610, the position of the body 122 can be sensed. The position of the body 122 can be sensed by a position sensor 123a disposed in a region of the body 122, and the position sensor 123a may include at least one of a magnetic field sensor, a limit switch, an optical sensor, and an ultrasonic sensor. For example, if the position sensor 123a includes a magnetic field sensor, a magnet may be disposed in the region of the holder 104 corresponding to the position sensor 123a.

[0213] Then, in operation 611, based on the sensed position of the subject 122, it can be determined whether the X-ray input device 100 is housed in the holder 104. Depending on the type of position sensor 123a, a reference value indicating that the subject 122 is housed in the holder 104 can be pre-stored. The reference value may have been stored as a predetermined reference range. The input controller 121 can compare the output from the position sensor 123a with the reference value to determine whether the subject 122 is housed in the holder 104.

[0214] If the input controller 121 determines that the body 122 is housed in the retainer 104 ("yes" in operation 612), then in operation 613, the input controller 121 may receive the output of the touch sensor 126 and perform calibration control based on the output of the touch sensor 126. See again Figure 10 The received output of the touch sensor 126 can be used as a capacitance reference value C1, and the capacitance threshold T1 can be determined based on the pre-stored minimum capacitance change D and the capacitance reference value C1, thereby performing calibration control.

[0215] Simultaneously, the input controller 121 may additionally use the output of the touch sensor 126 to determine whether to perform calibration control. In this example, the input controller 121 may perform calibration control when the X-ray input device 120 is housed in the holder 104 and the output of the touch sensor 126 exceeds the capacitance threshold T1.

[0216] In addition, to further improve the accuracy of calibration control command input, such as Figure 24 As shown, in operation 612a, input controller 121 can determine whether radiation button 124 is pressed. When input controller 121 determines that radiation button 124 is pressed ("yes" in operation 612a), input controller 121 can determine that a calibration control command has been input. For example, when a pressure higher than or equal to a first threshold pressure and lower than a second threshold pressure is applied to radiation button 124, thereby outputting a first signal from radiation button 124, input controller 121 can determine that radiation button 124 is pressed, thereby inputting a calibration control command.

[0217] Figure 25 and Figure 26 This is a flowchart illustrating a method for controlling an X-ray input device according to another embodiment. The X-ray input device 220 according to the other embodiment described above can be applied to the method for controlling an X-ray input device according to the current embodiment.

[0218] According to the method of controlling the X-ray input device, such as Figure 25 As shown, in operation 620, ambient environmental information can be acquired. This ambient environmental information can be acquired by an environmental sensor 223b disposed in an area of ​​the main body 222, and the environmental sensor 223b may include at least one of a temperature sensor and a humidity sensor. Therefore, the acquired ambient environmental information may include at least one of temperature information and humidity information.

[0219] Then, in operation 621, it can be determined whether the automatic calibration conditions are met based on the surrounding environmental information. For example, if the surrounding environmental information exceeds the reference range, it can be determined that the automatic calibration conditions are met, and calibration control can be performed automatically. The reference range can be set to a range of given values, or the reference range can be reset each time calibration is performed. The reference range used to determine the automatic calibration conditions has been described in detail in the embodiment of the X-ray input device 220 above.

[0220] If the automatic calibration conditions are met ("Yes" in operation 622), the output of touch sensor 226 can be received in operation 623, and calibration control can be performed based on the output of touch sensing portion 126 in operation 624.

[0221] Furthermore, the condition that the X-ray input device 220 is housed in the holder 104 can be added to the automatic calibration conditions. In this example, such as Figure 26 As shown, in operation 622a, it can be determined whether the X-ray input device 220 is housed in the holder 104 based on the position of the body 222. If it is determined that the body 222 is housed in the holder 104 ("yes" in operation 622a), then in operation 624, the output of the touch sensor 226 can be received, and calibration control can be performed based on the output of the touch sensor 226.

[0222] According to another example, operator-free operation can be added under automatic calibration conditions. In this example, input controller 221 can perform calibration control when the output of ambient sensor 223b is outside the reference range and the output of touch sensor 226 exceeds the capacitance threshold.

[0223] exist Figure 26 In this process, it can be first determined whether the surrounding environmental information is outside the reference range; however, the method of controlling the X-ray input device 220 is not limited to this. In other words, the order in which the X-ray input device 220 is determined to be housed in the holder 104 and the order in which the surrounding environmental information is determined to be outside the reference range is not limited.

[0224] Figure 27 The process of controlling an X-ray input device according to yet another embodiment is illustrated. The X-ray input device 320 according to the above embodiment can be applied to the method of controlling an X-ray input device according to the present embodiment.

[0225] According to such Figure 27 The method of controlling the X-ray input device 320 shown can determine that a calibration control command has been entered when the operator's input is received by the radiation button 324 and the calibration button 329 ("Yes" in operation 630), and the calibration control can be executed in operation 631.

[0226] According to the current embodiment, an operator can input a calibration command by simultaneously pressing the calibration button 329 and the radiation button 324. If the calibration button 329 is touched or pressed, the calibration button 329 can generate a third signal and transmit the third signal to the input controller 321. If the input controller 321 receives the third signal from the calibration button 329 and the first signal from the radiation button 324, the input controller 321 can determine that a calibration command has been input.

[0227] Additionally, the input controller 321 may use the output of the touch sensor 326 to determine whether to perform calibration control. In this example, when the input controller 321 receives a third signal from the calibration button 329 and a first signal from the radiation button 324, the input controller 321 may perform calibration control if the output of the touch sensor 326 exceeds a capacitance threshold.

[0228] In the X-ray input device, the X-ray imaging device including the X-ray input device, and the method for controlling the X-ray input device according to the above embodiments, by performing calibration control only when the user intends to perform calibration control or needs calibration control, unnecessary and inaccurate performance of calibration control can be prevented.

[0229] The following effects can be expected from the X-ray input device and control method disclosed herein.

[0230] First, by performing calibration control only when the X-ray input device is housed in the retainer, the operational accuracy of the X-ray input device can be improved.

[0231] Furthermore, the operational accuracy of the X-ray input device can be improved by performing calibration control on the touch sensor when outputting a preparation signal for each of the multiple input devices.

[0232] Furthermore, by performing calibration control on the touch sensor based on sensor value information from the sensor installed in the X-ray input device, automatic calibration control of the touch sensor can be performed without requiring separate user operation.
