[0002] X-rays are electromagnetic radiation with wavelengths between ultraviolet rays and gamma rays. X-rays have penetrability and different penetration capabilities for substances with different densities. In medicine, X-rays are generally projected onto human organs and bones to form medical images.

[0003] An X-ray imaging system usually includes an X-ray generating component, a chest radiography stand (Bucky-wall-stand, BWS) component, an examination table (table) component, a flat panel detector, and a remote control host, etc. The X-ray generating component emits X-rays that penetrate the irradiated object by using the high voltage provided by a high voltage generator, and forms medical image information of the irradiated object on the flat panel detector. The flat panel detector sends the medical image information to the control host, and the control host generates a medical image. The irradiated object can stand near the chest radiography stand component or lie on the examination table component, so as to respectively receive X-ray imaging of various parts such as the head, chest, abdomen, and joints.

[0081] Specific Embodiments

[0082] To make the objectives, technical solutions and advantages of the present invention clearer, the following examples are given to further elaborate on the present invention. In this patent application, nouns and pronouns related to people are not limited to specific genders.

[0083] For the sake of brevity and intuitiveness in description, the solutions of the present invention will be elaborated below by describing several representative embodiments. A large number of details in the embodiments are only used to help understand the solutions of the present invention. However, it is obvious that the technical solutions of the present invention can be implemented without being limited to these details. In order to avoid unnecessarily obscuring the solutions of the present invention, some embodiments are not described in detail, but only the frameworks are given. Hereinafter, "comprising" means "including but not limited to", and "according to..." means "at least according to..., but not limited to only according to...". Due to the language habits of Chinese, when the quantity of a component is not specifically indicated hereinafter, it means that the component can be one or more, or can be understood as at least one.

[0084] The flat panel detector plays a key role in the imaging quality. After observation, the applicant found the following phenomenon: interference patterns may appear in the medical images generated based on the medical image information collected by the flat panel detector. The applicant studied the reasons for this phenomenon and further found that: currently, the flat panel detector is often in a charging state during exposure, and the charging current will cause electromagnetic interference, resulting in interference patterns in the finally generated medical images.

[0085] Figure 1 is a schematic structural diagram of the charging system of the flat panel detector in the prior art. In Figure 1 it, the direct current flowing out from the power supply 10 first flows through the filter 11 to remove the ripple in the direct current, and then the direct current reaches the flat panel detector 12, so as to charge the battery in the flat panel detector 12.

[0086] Currently, during the exposure process of an X-ray imaging system (such as various X-ray medical imaging devices), it is necessary to first preheat the X-ray tube and then start the exposure logic. The user manually presses the switch in the console to provide a tube preheating signal (generally referred to as the VK signal) for controlling the tube preheating and an exposure signal (generally referred to as the HK signal) for performing the exposure. The generation time of the tube preheating signal is earlier than the generation time of the exposure signal. When the exposure ends, the user releases the switch, and the tube preheating signal will disappear.

[0087] In an embodiment of the present invention, after detecting a tube preheating signal, the charging circuit of the flat panel detector is disconnected to prevent electromagnetic interference caused by the flat panel detector working while charging. Moreover, after detecting the disappearance of the tube preheating signal after the exposure ends, the charging of the flat panel detector is restored. Preferably, charging is restored after a delay of several seconds (for example, 3 - 12 seconds) to provide sufficient working time for the flat panel detector. In addition, the embodiment of the present invention provides multiple input signals to implement different types of charging control logics. These input signals include switch signals representing the open or closed state of a switch and digital level signals (for example, 24 volts) from different signal sources, and are applicable to various types of application scenarios.

[0088] The above disclosure details the technical defects existing in the prior art, the reasons for these technical defects, and the thought analysis process for overcoming these technical defects. In fact, the recognition of the above technical defects is not common knowledge in this field, but a novel discovery by the applicant in the research. In addition, the reason tracing of the technical defects and the thought analysis process for overcoming these technical defects are also the gradual analysis results of the applicant in the actual research process, and are not common knowledge in this field.

[0089] Figure 2 is a schematic structural diagram of a charging control system for a flat panel detector according to an embodiment of the present invention. In Figure 2 it, the charging control device 22 of the flat panel detector 24 is connected between the power supply 25 and the battery 26 of the flat panel detector 24. Preferably, a filter 23 is further arranged between the charging control device 22 and the flat panel detector 24.

[0090] When the battery 26 is in a charging state, the current flow direction of the charging circuit from the power supply 25 to the battery 26 is as follows: the direct current flowing out from the power supply 25 reaches the charging control device 22. The charging control device 22 transmits the direct current to the filter 23. The filter 23 removes the ripple in the direct current, and then the direct current reaches the flat panel detector 24, thereby charging the battery 26 in the flat panel detector 24.

[0091] When the charging control device 22 receives a first signal indicating that the X-ray tube of the X-ray imaging system is in a preheating state, the charging circuit from the power supply 25 to the battery 26 is disconnected. When the charging control device 22 detects the disappearance of the first signal, the charging circuit from the power supply 25 to the battery 26 is restored.

[0092] The first signal can be a digital level signal 20 or a switch signal 21.

[0093] In one embodiment: The user manually operates a switch in the operation console to generate a switch signal 21 representing the open or closed state of the switch. This switch signal is specifically a tube preheating signal for controlling the preheating of the X-ray tube. Via the cable between the operation console and the charging control device 22, the switch signal 21 is sent to the charging control device 22. After receiving the switch signal 21, the charging control device 22 disconnects the charging circuit from the power supply 25 to the battery 26. Moreover, the charging control device 22 sends the switch signal 21 to the X-ray tube via the cable between it and the X-ray tube. The X-ray tube enters the preheating state based on the switch signal 21. When the charging control device 22 detects the disappearance of the switch signal 21, it restores the charging circuit from the power supply 25 to the battery 26. It can be seen that in this embodiment, the charging control logic of the battery is implemented based on the switch of the operation console, enriching the flexibility of control. Moreover, the charging control device 22 can also provide the switch signal to the control unit of the X-ray tube, ensuring the normal preheating process of the tube.

[0094] In one embodiment: The user manually operates a switch in the operation console to generate a switch signal 21 representing the open or closed state of the switch. This switch signal 21 is specifically a tube preheating signal for controlling the preheating of the X-ray tube. Via the cable between the operation console and the X-ray tube, the switch signal 21 is sent to the X-ray tube. The X-ray tube enters the preheating state based on the switch signal 21. Moreover, the X-ray tube (usually the control unit in the X-ray tube) generates a digital level signal 20 based on the switch signal 21, where when the switch signal 21 disappears, the digital level signal 20 disappears synchronously. For example, the digital level signal 20 can be implemented as a digital level signal of 24 volts. Via the cable between the X-ray tube and the charging control device 22, the digital level signal 20 is sent to the charging control device 22. After receiving the digital level signal 20, the charging control device 22 disconnects the charging circuit from the power supply 25 to the battery 26. When the charging control device 22 detects the disappearance of the digital level signal 20, it restores the charging circuit from the power supply 25 to the battery 26. It can be seen that in this embodiment, the charging control logic of the battery can be implemented based on the control unit of the X-ray tube, enriching the flexibility of control.

[0095] In one embodiment: A user generates a digital level signal 20 at the control host of an X-ray imaging system. For example, the digital level signal 20 can be implemented as a digital level signal of 24 volts. The digital level signal 20 is sent to the charging control device 22 via a cable between the control host and the charging control device 22. After receiving the digital level signal 20, the charging control device 22 disconnects the charging circuit from the power supply 25 to the battery 26. When the charging control device 22 detects the disappearance of the digital level signal 20, it restores the charging circuit from the power supply 25 to the battery 26. In this embodiment, the charging control logic of the flat panel detector can be controlled by the digital level signal provided by the control host. It can be seen that it is not necessary for the X-ray tube to actually enter the preheating state and exposure, and the control host can control the charging control logic of the flat panel detector, realizing various simulation tests for the flat panel detector.

[0096] Figure 3 It is a schematic structural diagram of a charging control device for a flat panel detector according to an embodiment of the present invention.

[0097] In Figure 3 it, the signal inputs of the charging control device 22 include: a digital level signal 20 and a switch signal 21. The switch signal 21 can be implemented as: a switch signal triggered on a switch of an operation console, such as an X-ray tube preheating signal for controlling the preheating of the X-ray tube. The digital level signal 20 can be implemented as: (1) a digital level signal received from a control unit of the X-ray tube, where the digital level signal is generated by the control unit based on a switch signal sent by the operation console; (2) a digital level signal received from the control host.

[0098] The charging control device 22 includes a switch module 31, a timing module 32, and an isolation protection module 30. The isolation protection module 30 is arranged between the switch module 31 and the digital level signal 21. The isolation protection module 30 can provide electrostatic protection and opto-isolation for the charging control device 22.

[0099] The switch module 31 is used to disconnect the charging circuit from the power supply 25 to the battery 26 when receiving the digital level signal 20 and / or the switch signal 21, where the digital level signal 20 and / or the switch signal 21 indicates that the X-ray tube of the X-ray imaging system is in the preheating state. After the digital level signal 20 and / or the switch signal 21 disappears, the switch module 31 sends a timing trigger signal to the timing module 32; the timing module 32 is used to start timing after receiving the timing trigger signal, and when reaching a predetermined timing time, send a timing arrival signal to the switch module 31; the switch module 31 is further used to connect the charging circuit from the power supply 25 to the battery 26 after receiving the timing arrival signal.

[0100] In one embodiment, the switch module 31 includes a normally open and normally closed relay, which comprises a coil, a normally closed contact and a normally open contact; wherein the normally open contact is used to provide a switch signal to the control unit of the X-ray tube; the coil is used to be powered on after receiving the switch signal; the normally closed contact is used to disconnect after the coil is powered on, so as to disconnect the charging circuit from the power supply 25 to the battery 26.

[0101] Figure 4 FIG. is a schematic diagram of the input of the switch signal and the charging control according to an embodiment of the present invention. The switch module 31 includes a normally open and normally closed relay k1. Between the contact 1 and the contact 8 of the relay k1 is the coil; the contact 3 and the contact 4 of the relay k1 are the normally closed contacts; the contact 5 and the contact 6 of the relay k1 are the normally open contacts. In Figure 4 FIG., when the user presses the switch 40 in the operation console, the coil of the relay k1 is powered on, and a switch signal representing the state of the switch 40 is generated between the contact 5 and the contact 6. This switch signal is provided to the X-ray tube to control the X-ray tube to perform a preheating process. After the coil of the relay k1 is powered on, the contact 3 and the contact 4 are opened, which can be used to cut off the charging circuit of the subsequent flat panel detector.

[0102] Figure 5 FIG. is a schematic diagram of the input and isolation of the digital level signal according to an embodiment of the present invention. In Figure 5 FIG., at the front end of the input of the digital level signal 20, an isolation protection module 30 is arranged. The isolation protection module 30 includes an electrostatic discharge unit 33 and an optocoupler isolation unit 34. For example, the electrostatic discharge unit 33 can be implemented as an electrostatic discharge circuit including two parallel electrostatic discharge protection diodes; the optocoupler isolation unit 34 can be implemented as an optocoupler isolation chip. It can be seen that based on the isolation protection module 30, the isolation protection of the external circuit for the charging control circuit is realized.

[0103] Figure 6 FIG. is a schematic structural diagram of the timing module according to an embodiment of the present invention. In Figure 6 FIG., the timing module 32 includes a 555 timer 35 and its external circuit. Different delay settings such as 3 seconds, 5 seconds, and 10 seconds can be selected through different DIP switches (s11~s13). When receiving the timing trigger signal 37 (Trig), the 555 timer 35 starts timing according to the set delay time, and outputs a timing arrival signal 36 after the delay time, so as to start the resumption of charging.

[0104] The above separately describes typical examples of the input of the switch signal and the charging control, the input and isolation of the digital level signal, and the timing module. Those skilled in the art can realize that this description is only exemplary and is not used to limit the protection scope of the embodiments of the present invention.

[0105] Figure 7 is a schematic circuit diagram of a charging control device according to an embodiment of the present invention. In Figure 7 the circuit shown, both the switch 40 and the digital level signal 20 can be used as input signal sources of the charging control device 22. The digital level signal 20 can be implemented as a digital level signal of 24 volts (24V). The digital level signal 20 can come from a control host or from a control unit of an X-ray tube. Moreover, an electrostatic discharge unit 33 and an opto-isolation unit 34 are arranged at the front end of receiving the digital level signal 20.

[0106] When the switch 40 is pressed, the input signal of the charging control device 22 is: the tube preheating signal (vk) provided by the switch 40. The coil of the relay k1 is powered on, and a switch signal representing the state of the switch 40 is generated between the normally open contacts of the relay k1. This switch signal is provided to the X-ray tube to control the X-ray tube to perform a preheating process, that is, to play the role of the vk signal. After the coil of the relay k1 is powered on, the normally closed contact of the relay k1 opens, the opto-coupler chip U2 is disconnected, and the 555 timer (U1) connected to the opto-coupler chip U2 is disconnected. The opto-coupler chip U3 connected to the 555 timer is also disconnected. Thus, the charging circuit between the power input terminals (including the positive terminal 38 of the 12V charging input and the negative terminal 39 of the 12V charging input) and the charging output terminals (including the positive terminal 41 of the 12V charging output and the negative terminal 42 of the 12V charging output) is disconnected, and the battery charging circuit of the flat panel detector is disconnected.

[0107] When the switch 40 is released, the tube preheating signal provided by the switch 40 disappears. At this time, the normally closed contact of the relay k1 closes, the opto-coupler chip U2 conducts, and the 555 timer (U1) connected to the opto-coupler chip U2 conducts. When the timing time of the 555 timer arrives, the opto-coupler chip U3 connected to the 555 timer conducts. Thus, the charging circuit between the power input terminals (including the positive terminal 38 of the 12V charging input and the negative terminal 39 of the 12V charging input) and the charging output terminals (including the positive terminal 41 of the 12V charging output and the negative terminal 42 of the 12V charging output) is restored, and the battery of the flat panel detector can continue to be charged.

[0108] When the digital level signal 20 is detected, the coil of the relay k1 is powered on, the normally closed contact of the relay k1 opens, the opto-coupler chip U2 is disconnected, and the 555 timer (U1) connected to the opto-coupler chip U2 is disconnected. The opto-coupler chip U3 connected to the 555 timer is also disconnected. Thus, the charging circuit between the power input terminals (including the positive terminal 38 of the 12V charging input and the negative terminal 39 of the 12V charging input) and the charging output terminals (including the positive terminal 41 of the 12V charging output and the negative terminal 42 of the 12V charging output) is disconnected, and the battery charging circuit of the flat panel detector is disconnected.

[0118] (1) A switch signal triggered on the switch of the operation console;

[0119] (2) A digital level signal received from the control unit of the X-ray tube, where the digital level signal is generated by the control unit based on the switch signal sent by the operation console;

[0127] An embodiment of the present invention also proposes an electronic device with a processor-memory architecture.

The hardware module can also include a programmable logic device or circuit temporarily configured by software (such as including a general-purpose processor or other programmable processors) for performing specific operations. As for whether to specifically use a mechanical method, a dedicated permanent circuit, or a temporarily configured circuit (such as configured by software) to implement the hardware module, it can be determined according to cost and time considerations.
