Description

An X-ray image acquisition system and an image transmission module and method thereof TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular to an image transmission module and method for an X-ray image acquisition system and the X-ray image acquisition system. BACKGROUND

[0002] As an auxiliary medical means, X-ray images have been widely used in clinical diagnosis such as dentistry, orthopedics, etc. The penetration of X-rays is related to the density of the material. The denser the material, the more X-rays are absorbed, and the less X-rays are transmitted. The less dense the material, the less X-rays are absorbed, and the more X-rays are transmitted. By utilizing the difference in absorption, the density of bones and muscles, fat and other soft tissues can be distinguished, and the information about the density distribution of the human body can be reflected through the brightness and darkness of the X-ray image.

[0003] For example, a dentist can use an X-ray image acquisition system to take X-ray photographs of teeth to obtain images for clinical diagnosis. Generally, an X-ray image acquisition system includes an X-ray generating device, an X-ray image sensor, and a transmission module. During the process of taking dental X-ray photographs, the image is acquired by the X-ray image sensor and transmitted to a computer system such as a PC for browsing through the transmission module. At present, the transmission module of most X-ray image acquisition systems includes a transmission cable, i.e. the X-ray image sensor is usually connected to a PC or the like through a wired mode such as a transmission cable. On the one hand, this limits the working range of the X-ray image sensor, and on the other hand, it also requires manual connection, image reading, and other operations before image acquisition, increasing the risk of cross infection.

[0061] In order to reduce the contact operation in the X-ray image acquisition and transmission process as much as possible, and to improve the image transmission efficiency and accuracy, the present application provides an image transmission module, method and X-ray image acquisition system for an X-ray image acquisition system, which can realize automatic WIFI pairing, image acquisition and transmission. The technical solutions of the present application will be further described below in conjunction with the embodiment drawings.

[0062] FIG. 1 shows a structural schematic diagram of an image transmission module for an X-ray image acquisition system according to an embodiment of the present application. As shown in FIG. 1, an image transmission module for an X-ray image acquisition system includes a handheld part 101 and a connecting part 102, wherein the handheld part 101 is paired with the connecting part 102 based on an RFID two-way communication protocol, and then establishes a WIFI connection with the connecting part 102. The handheld part 101 is used to acquire X-ray images and send them to the connecting part 102 through WIFI, and the connecting part 102 further transmits the X-ray images to a computer system 001.

[0063] FIG. 2 shows a structural schematic diagram of a handheld part of an image transmission module for an X-ray image acquisition system according to an embodiment of the present application. As shown in FIG. 2, in an embodiment of the present application, the handheld part includes a first control submodule 111, an X-ray image sensor 112, an RFID tag 113, and a first WIFI submodule 114.

[0064] The first control submodule 111 is used to control other submodules of the handheld part to realize WIFI pairing, connection, and image shooting and transmission operations. In an embodiment of the present application, the first control submodule 111 can be, for example, a single-chip microcomputer or the like.

[0065] The X-ray image sensor 112 is communicatively connected with the first control submodule 111 through a USB cable based on USB transmission protocol, which can be controlled by the first control submodule 111 to enter an image acquisition state to take an X-ray image and send it to the first control submodule 111. In an embodiment of the present application, the handheld part further comprises a storage unit, when the handheld part is in poor communication with the connecting part, the X-ray image can be stored in the storage unit, and then sent to the computer system through the connecting part after the communication is restored. In an embodiment of the present application, the storage unit comprises a non-volatile memory. In addition, in an embodiment of the present application, the X-ray image sensor 112 is a light-sensitive trigger, which automatically starts exposure and generates an X-ray image after detecting the X-ray flash emitted by the X-ray generator.

[0066] The RFID tag 113 conforms to the RFID two-way communication protocol, which is communicatively connected with the first control submodule 111. The connecting part has confirmed the identity of the handheld part by reading the information of the RFID tag 113, and then provides WIFI connection information to establish WIFI connection. The first WIFI submodule 114 is communicatively connected with the first control submodule 111, and can be connected with the connecting part based on the WIFI connection information sent by the connecting part. In an embodiment of the present application, the WIFI connection information mainly includes the hotspot name and password established by the connecting part.

[0067] In order to further improve the connection accuracy, in an embodiment of the present application, in addition to the identity confirmation through the RFID two-way communication protocol, the handheld part is further provided with an acceleration sensor 115. The acceleration sensor 115 can sense the motion state of the handheld part, and then activate the pairing operation only when the handheld part is in the motion state close to the connecting part. In an embodiment of the present application, the RFID tag is initially set to an unreadable state, and when the acceleration sensor 115 detects the motion of the handheld part, the RFID tag is set to a readable state by the first control submodule 111, and then the pairing operation is activated. In an embodiment of the present application, the RFID tag is always in a readable state, and in the secondary verification, it is determined whether the pairing is successful based on the detection result of the acceleration sensor 115. If the handheld part is stationary, the pairing is cancelled, and if the handheld part is in a motion state when establishing a TCP connection, the pairing is successful, and subsequent image transmission operations can be performed. In addition, the acceleration sensor 115 can also be used to wake up the handheld part after sensing a specified action to activate the image acquisition state. In an embodiment of the present application, the handheld part can be awakened by double-clicking the shell of the handheld part, etc.

[0068] In an embodiment of the present application, the hand-held part is powered by a built-in battery 117, which is a rechargeable battery, which in an embodiment of the present application can be wirelessly charged through the connecting part.

[0069] In an embodiment of the present application, the hand-held part further comprises a status indicator light 116. The status indicator light 116 displays the status of the hand-held part by color and / or blinking state, such as successful pairing with the connecting part, failed pairing, disconnection, image acquisition state, etc.

[0070] Figure 3 shows a structural schematic diagram of a connecting part of an image transmission module of an X-ray image acquisition system according to an embodiment of the present application. As shown in Figure 3, in an embodiment of the present application, the connecting part comprises a second control submodule 121, an RFID reader / writer 122, a second WIFI submodule 123, and an external interface 124.

[0071] The second control submodule 121 is used to control other submodules of the connecting part to perform operations such as starting a WIFI hotspot, WIFI pairing, and image transmission. In an embodiment of the present application, the second control submodule 121 can be, for example, a single-chip microcomputer, etc.

[0072] The RFID reader 122 is communicatively connected with the second control submodule 121, which is used to obtain the RFID tag information of the handheld part to verify the identity of the handheld part. The second WIFI submodule 123 is used to establish a WIFI hotspot, which is communicatively connected with the second control submodule 121. When the identity verification of the handheld part is passed, the name and password of the WIFI hotspot are sent to the handheld part. In an embodiment of the present application, after the handheld part reads the hotspot name and password, the TCP communication is established through WIFI and the connection part, and then the identity confirmation and the transmission of related parameters are performed again based on the TCP connection to complete the pairing. Specifically, in an embodiment of the present application, after the handheld part and the connection part establish the TCP connection, the handheld part sends its unique identification number, motion state, model, factory date, service life, bad point compensation information, battery power, temperature and other information to the connection part through the TCP connection, and the connection part transmits the above information to the computer system. The computer system judges whether the handheld part is legal and whether it is in a usable state based on the above information. If yes, it is determined that the pairing is successful, and subsequent image transmission and other operations can be performed. If the handheld part is illegal and / or the handheld part is in an unusable state, an error is prompted. The handheld part being illegal, for example, means that the handheld part is in a stationary state when establishing the TCP connection, or its identification code is inconsistent with the expected handheld part for operation, and the handheld part being in an unusable state, for example, can include that the power of the handheld part is lower than a preset value, the temperature is higher than a preset value, the performance of the X-ray image sensor is reduced to affect the picture quality, and the like.

[0073] The external interface 124 is used to connect with the computer system to transmit the X-ray image to the computer system. In an embodiment of the present application, the connection part is communicatively connected with the computer system based on the USB protocol, that is, the external interface 124 is a USB interface.

[0074] Correspondingly, in an embodiment of the present application, the connection part also includes a charging submodule 128, which charges the built-in battery of the handheld part under the control of the second control submodule 121. The connection part itself can be powered by an external power source 002 and / or its built-in battery through the external power source interface 125, and is also provided with a charging indicator 126.

[0075] Similarly, the connection part is also provided with a state indicator 127 for displaying the state of the connection part. In an embodiment of the present application, in order to facilitate the user to observe, the state indicator of the connection part adopts a more eye-catching form, for example, the state indicator can include a plurality of LEDs, and the LEDs form some specific and more eye-catching shapes, such as a ring-shaped lamp strip around the body of the connection part, or other lamp zones with shapes such as a circle, a star and the like.

[0076] In one embodiment of the present application, the image transmission module can include a plurality of handheld units and / or a plurality of connection units, but the connection unit can only connect one handheld unit at a time. When multiple handheld units are close at the same time, the connection unit can obtain the RFID tag information of the multiple handheld units and confirm the correct handheld unit to establish a TCP connection. Even if an incorrect handheld unit establishes a TCP connection with it, the pairing process can still be interrupted by secondary verification until the correct handheld unit is connected. In this process, the successful pairing of the handheld unit can be confirmed by the status indicator light of the handheld unit and the connection unit. In addition, when the connection unit is in working condition, i.e. the handheld unit connected to it is in image acquisition state, if a new handheld unit is close, the connection unit can directly verify that it is not passed after reading the new RFID tag information, interrupt the pairing request of the new handheld unit. Even if a new handheld unit mistakenly establishes a TCP connection with it, the pairing process of the new handheld unit can still be interrupted by secondary verification.

[0077] Based on the image transmission module as described above, Figure 4 shows a flowchart of an image transmission method for an X-ray image acquisition system according to one embodiment of the present application. As shown in Figure 4, an image transmission method for an X-ray image acquisition system includes:

[0078] First, in step 401, the device is connected. The connection unit is connected to the computer system. In actual application, only when it is used for the first time, the connection unit needs to be connected to the computer system through, for example, USB, etc. Subsequently, it is not necessary to repeatedly plug and unplug, and contact operation is avoided as much as possible.

[0079] Next, in step 402, the pairing connection. The handheld part is close to the connection part to WIFI pairing connection. Specifically, in an embodiment of the present application, when the handheld part is close to the connection part, the acceleration touch sensor senses that the handheld part is in motion, and then starts the RFID pairing process, that is, makes the RFID tag readable. When the distance between the handheld part and the connection part is less than or equal to a preset value, the connection part acquires the RFID tag information of the handheld part through the RFID reader and writer to verify the identity of the handheld part. If the verification is passed, the connection part sends the WIFI connection information such as the hotspot name and password of the connection part to the handheld part. The handheld part establishes TCP communication with the connection part according to the WIFI connection information. If the verification is not passed, an error is reported through a state indicating lamp or an alarm sound. In another embodiment of the present application, the RFID tag is always readable. Once the distance between the handheld part and the connection part is less than or equal to a preset value, the connection part can acquire the RFID tag information to verify whether to establish TCP connection. In an embodiment of the present application, the preset value is not greater than 10 cm, preferably not greater than 5 cm. In an embodiment of the present application, in order to avoid misconnection, after establishing TCP communication, the handheld part and the connection part perform secondary verification to further verify the identity, use state and other information of the handheld part. If the secondary verification is passed, the pairing is successful, and the preset parameters can be transmitted to facilitate subsequent image transmission. If the secondary verification is not passed, the pairing process is interrupted, and pairing failure is prompted. Different state indicating lamp states and / or computer system interface can be used to display specific pairing failure reasons. After successful pairing, the ACQ acquisition software of the computer system automatically jumps to the front window and displays the pairing and the names of the paired handheld part and connection part through the corresponding interface. In an embodiment of the present application, the connection part and the handheld part can prompt the user of successful pairing by changing the flashing mode and color of the state indicating lamp. Since the connection part can only be connected with one handheld part at a time, in an embodiment of the present application, in order to avoid the situation of one connection with multiple devices and multiple connections with one device, before the handheld part is close to the connection part, it needs to be disconnected from all handheld parts. For example, a disconnection button can be arranged on the connection part, and the RFID tag information in the connection part can be cleared by long pressing. In another embodiment of the present application, the confirmation is performed during the pairing process. Specifically, after the connection part acquires the RFID tag information, it first confirms whether there is a paired handheld part. If not, it directly pairs and connects. If yes, it first disconnects from the currently paired handheld part, and then pairs and connects with the handheld part to be paired. When the handheld part and the connection part connected by WIFI TCP connection are disconnected, the connection part notifies the handheld part that it has been disconnected. After receiving the notification, the handheld part enters an unpaired state.

[0080] Finally, in step 403, the image is acquired. The handheld part is woken up to acquire the X-ray image, which is automatically transmitted to the connection part via WIFI and sent to the computer system. In an embodiment of the present application, the acceleration sensor sends a signal to the first control submodule after sensing a preset action such as double-clicking the shell of the handheld part, and the first control submodule controls the X-ray image sensor to enter the image acquisition state. At this time, the handheld part can prompt that it has entered the image acquisition state through the state indicator light. Meanwhile, the first control submodule also sends corresponding information to the connection part to inform the ACQ acquisition software of the computer system to enter the image acquisition state. At this time, the X-ray generator (ball tube) emits X-ray flash, and the X-ray image sensor senses the start of X-ray exposure. After exposure is completed, the image is automatically uploaded to the computer system via WIFI, and the ACQ acquisition software automatically displays the picture and gives corresponding image analysis. Step 403 can be repeated to complete multiple image acquisition. It should be understood that in an embodiment of the present application, the user can also directly operate on the computer system to wake up the handheld part and the ACQ acquisition software to enter the image acquisition state.

[0081] In an embodiment of the present application, after the image acquisition is completed, if the handheld part is stationary for a preset time period, it will automatically enter the sleep state. In the sleep state, the handheld part can also be woken up by a preset action. For a paired handheld part, it directly enters the image acquisition state, while for an unpaired handheld part, it gives a prompt through the indicator light and continues to sleep. In an embodiment of the present application, the preset time period is 5 to 10 minutes.

[0082] Based on the image transmission module and method as described above, the present application further provides an X-ray image acquisition system, which comprises the image transmission module as described above.

[0083] Although the above describes embodiments of the present application, it should be understood that they are presented only as examples and not as limitations. It is obvious to those skilled in the relevant art that various combinations, variations and changes can be made without departing from the spirit and scope of the present application. Therefore, the breadth and scope of the present application disclosed herein should not be limited by the above disclosed exemplary embodiments, but should only be defined according to the appended claims and their equivalent replacements.
