Description

Technical Field

[0001] This application belongs to the technical field of detectors, relates to a detector anti-interference technology, and particularly relates to a detector panel, a detector, a detector imaging method, a terminal, and a medium. Background Art

[0002] As a detection device, a detector is widely used in fields such as medical imaging, industrial inspection, and scientific research experiments. Its detection principle is: the detector panel receives ray signals and converts them into image data as the detection result. It should be noted that there is also external electromagnetic radiation in the working environment of the detector. For example, the electromagnetic radiation generated by external electronic devices such as motors and transistors. When these external electromagnetic radiations are received by the detector, they will become interference signals, thus affecting the imaging effect of the detector.

[0003] In the prior art, in order to avoid the influence of external interference signals on the detection result of the detector, shielding materials, such as alloy materials, are usually added to the detector panel to shield the external electromagnetic radiation interference signals, thereby improving the anti-interference ability of the detector. However, while shielding external electromagnetic radiation, these shielding materials will inevitably shield the ray signals, affecting the reception of ray signals by the detector panel, and further reducing the sensitivity of the detector to ray signals, resulting in a poor imaging effect of the detector. At the same time, since the thickness of the shielding material is usually not uniform, that is, the shielding degree of the ray signals at different parts of the shielding material is different, the ability of different parts of the detector panel to receive ray signals is not the same, resulting in poor uniformity of the image data obtained by the detector, and further deteriorating the imaging effect of the detector. Summary of the Invention

[0004] The purpose of this application is to provide a detector panel, a detector, a detector imaging method, a terminal, and a medium, which are used to solve the problem in the prior art that while adding a shielding material to the detector panel to shield external electromagnetic radiation interference signals, it affects the reception of ray signals by the detector panel, resulting in poor image quality of the detector.

[0005] In a first aspect, this application provides a detector panel, including: a signal reading unit for receiving and reading signals and transmitting them to an external processing unit; a signal receiving unit for receiving detection signals and sending the detection signals to the signal reading unit; an interference receiving unit for receiving interference signals and sending the interference signals to the signal reading unit; wherein, the signal receiving unit and the interference receiving unit are arranged at intervals; the detection signals include ray signals and interference signals; and the external processing unit subtracts the detection signals from the interference signals.

[0006] This application receives interference signals through an interference receiving unit to cancel the interference signals received in the signal receiving unit, thereby realizing the anti-interference function of the detector. At the same time, since the interference receiving unit has no influence on the process of the signal receiving unit receiving signals, the detector panel can still receive ray signals well, so that the final imaging quality of the detector is relatively high, achieving a better imaging effect.

[0007] In an embodiment of the present application, the interference receiving unit includes an interference signal transmission line; one end of the interference signal transmission line is connected to the signal reading unit, and the other end is a grounding end. It should be noted that no photoelectric conversion element is provided in the interference receiving unit, so that the interference receiving unit cannot receive ray signals, that is, the interference receiving unit only receives the interference signals.

[0008] In an embodiment of the present application, the interference receiving unit further includes a high-pass filtering element, which is connected to the grounding end of the interference signal transmission line and is used to filter the noise in the interference signal transmission line to avoid the influence of such noise on the signal subtraction process of the detector, further improving the accuracy of the detection result.

Specific embodiments

[0028] The following specific examples illustrate the implementation manners of the present application. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0029] It should be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concept of the present application. Therefore, only the components related to the present application are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, quantities, and proportions of the components in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0030] The following embodiments of the present application provide a detector panel, a detector, a detector imaging method, a terminal, and a medium, which are used to eliminate the influence of external interference signals on the detection result. Currently, the anti-interference technology of detectors is mainly achieved by adding shielding materials to the detector panel. However, since the shielding materials will affect the reception of ray signals by the detector panel, this anti-interference method will cause the imaging effect of the detector panel to deteriorate. Based on this, the detector panel, detector, detector imaging method, terminal, and medium provided by the present application receive interference signals through an interference receiving unit and combine them with the ray signals and interference signals received by the signal receiving unit to cancel the interference signals received by the detector panel. While avoiding the interference of external interference signals on the detection result of the detector, it will not affect the reception of ray signals by the detection panel, thereby improving the detection accuracy and image quality of the detector and achieving a better detection effect.

[0031] The following embodiments of the present application provide a detector panel, a detector, a detector imaging method, a terminal, and a medium, including but not limited to the structure applied to a thin-film transistor detector panel, to avoid the influence of external interference signals on the imaging of the thin-film transistor detector. The following will describe the detector as an example of a thin-film transistor detector. Of course, the detector panel provided by the present application can also be other types of detector panels, and the present application does not make specific limitations here.

[0032] The following will elaborate on the principles and implementation manners of a detector panel, a detector, a detector imaging method, a terminal, and a medium of this embodiment in conjunction with the accompanying drawings, so that those skilled in the art can understand the detector panel, the detector, the detector imaging method, the terminal, and the medium of this embodiment without creative labor.

[0033] As Figure 1 shown, this embodiment provides a detector panel for receiving ray signals and converting them into image data. Specifically, the detector panel includes a signal reading unit 300, and a plurality of signal receiving units 100 and interference receiving units 200. Among them, the signal reading unit 300 is used to receive and read signals and transmit them to an external processing unit. The signal receiving unit 100 is used to receive ray signals and transmit the ray signals to the signal reading unit 300, so that the external processing unit can generate image data based on these ray signals and display the detection result.

[0034] It should be noted that there are usually certain interference signals in the working environment of the detector, such as electromagnetic radiation generated when external devices work. While the signal receiving unit 100 receives ray signals, it will also receive these interference signals. That is, the detection signal received by the signal receiving unit 100 is actually a signal formed by the superposition of ray signals and interference signals. If image data is generated based on this detection signal, it will be affected by the interference signal, resulting in an inaccurate detection result finally displayed. Based on this, the detector panel provided by this embodiment further includes an interference receiving unit 200 for receiving interference signals. Since the interference receiving unit 200 and the signal receiving unit 100 receive signals simultaneously and the interference signals received by the two are the same, based on this, subtracting the signal received by the interference receiving unit 200 from the detection signal received by the signal receiving unit 100 can remove the interference signal received by the signal receiving unit 100, thereby eliminating the influence of external interference on the imaging of the detector. At the same time, since the interference receiving unit 200 does not affect the signal reception of the signal receiving unit 100, it will not cause the sensitivity of the detector panel to ray signals to decrease, and thus ensures the quality of the image data obtained by the detector, making the detector have a good imaging effect.

[0035] Furthermore, the signal receiving unit 100 and the interference receiving unit 200 are arranged at intervals to facilitate the interference receiving unit 200 to receive interference signals from various parts of the detector panel, thereby further improving the anti-interference effect of the detector panel. Further, the signal receiving unit 100 and the interference receiving unit 200 are arranged at intervals and evenly, that is, between any two adjacent interference receiving units 200, the number of signal receiving units 100 is a preset number, so that the arrangement of the signal receiving units 100 on the detector panel is relatively uniform, thereby improving the uniformity of the image data obtained by the detector, and further improving the imaging effect of the detector. Exemplarily, the preset number is 2 or 3.

[0036] It should be noted that by subtracting the signal received by the signal receiving unit 100 from the signal received by the interference receiving unit 200, the interference signal received by the detector panel can be cancelled. Specifically, both the signal receiving unit 100 and the interference receiving unit 200 are communicatively connected to the signal reading unit 300, and the detection signal and the interference signal are transmitted to the external processing unit through the signal reading unit 300. The external processing unit processes the detection signal and the interference signal, performs the subtraction process of the signals, and uses the signal obtained after subtraction as the imaging signal, and generates image data for display based on this, thereby realizing the anti-interference of the detector. Among them, the external processing unit can be the processing unit in the external terminal communicatively connected to the detector, or the processing unit in the core controller of the detector, as long as it can receive signals from the signal receiving unit 100 and the interference receiving unit 200 and perform subtraction calculations. This embodiment does not make specific limitations here.

[0037] It should be noted that those skilled in the art should be aware of the specific implementation method and principle of signal subtraction, and this embodiment does not make specific explanations here.

[0038] In some alternative embodiments, the signal receiving unit 100 and the interference receiving unit 200 are arranged horizontally at intervals. At this time, a single signal receiving unit 100 actually represents a single row or a single column of pixels on the detector panel. Specifically, as Figure 2 shown, the signal receiving unit 100 includes at least one signal conversion component 110 and a detection signal transmission line 120 connecting the signal conversion component 110. Among them, each signal conversion component 110 actually represents a single pixel on the detector panel. Each signal conversion component 110 receives the ray signal and transmits it through the detection signal transmission line 120, so as to realize the display of each pixel in a single row or a single column on the detector panel. Further, the detection signal transmission line 120 is connected to the signal reading unit 300 to transmit the detection signal to the signal reading unit 300.

[0039] It should be noted that each signal conversion component 110 is used to receive a ray signal and convert it into an electrical signal, and the detection signal transmission line 120 is used to transmit the electrical signals from the connected signal conversion components 110.

[0040] In some alternative embodiments, the signal conversion component 110 includes a scintillator (not shown in the figure) and a photoelectric conversion element 111 connected to the detection signal transmission line 120. Among them, the scintillator is used to convert the ray signal into a visible light signal, and the photoelectric conversion element 111 is used to convert the visible light signal into an electrical signal for transmission through the detection signal transmission line 120. Exemplarily, the photoelectric conversion element 111 is a photodiode. It should be noted that the scintillator can cover the entire detector panel in the form of a film, or scintillator units corresponding to each pixel can be formed, and each scintillator unit is disposed on the surface of each corresponding pixel to cover the entire detector panel.

[0041] In some alternative embodiments, the detector panel further includes a switch control unit 400, and the signal conversion component 110 further includes a switch element 112 disposed between the detection signal transmission line 120 and the photoelectric conversion element 111. Whether each switch element 112 is turned on or off is controlled by the switch control unit 400, thereby controlling the operation of each signal receiving unit 100, that is, whether each signal receiving unit 100 transmits a detection signal. Exemplarily, the switch element 112 is a thin film transistor. The source electrode of the thin film transistor is connected to the detection signal transmission line to transmit the electrical signal through the source electrode. The gate electrode of the thin film transistor is connected to the switch control unit 400, and the switch control unit 400 controls the on and off of the thin film transistor, thereby realizing the control of the electrical signal transmission.

[0042] Based on this, the signal receiving unit 100 converts the received ray signal into a visible light signal through the scintillator. The visible light signal is received by the photoelectric conversion element 111 and converted into an electrical signal, and the electrical signal is transmitted through the detection signal transmission line 120, thereby realizing the reception and transmission of the ray signal by the detector panel.

[0043] It should be noted that since the signal receiving unit 100 also transmits an external electromagnetic radiation interference signal while receiving the ray signal, that is, the detection signal received by the signal receiving unit 100 actually includes a ray signal and an interference signal. Based on this, it is necessary to receive the interference signal through the interference receiving unit 200 and combine it with the signal transmitted by the signal receiving unit 100 to cancel the interference signal.

[0044] Specifically, as Figure 3As shown, the interference receiving unit 200 includes an interference signal transmission line 210, wherein one end of the interference signal transmission line 210 is connected to the signal reading unit 300 to transmit the interference signal to the signal reading unit 300, and the other end is a ground terminal. It is worth noting that compared with the signal receiving unit 100, the interference receiving unit does not include the signal conversion component 110. More specifically, the interference signal transmission line 210 is not connected to the photoelectric conversion element 111. When the radiation signal is incident on the detector panel, the interference receiving unit 200 cannot convert the radiation signal into an electrical signal for transmission. Therefore, the interference receiving unit 200 cannot receive the radiation signal, that is, the interference receiving unit 200 only transmits the interference signal. Further, the interference signal transmission line 210 is actually the same conductor as the detection signal transmission line 120.

[0045] Based on this, Figure 4 As shown, the detector panel provided in this embodiment is actually a detector panel that adds a number of interference signal transmission lines 210 for only receiving and transmitting external electromagnetic radiation interference signals, so that the signals transmitted by the interference signal transmission lines 210 are combined with the signals transmitted by each pixel on the detector panel, thereby eliminating the influence of the interference signal, and these added interference signal transmission lines 210 do not affect the reception of the radiation signal by each pixel on the detector panel, and therefore will not affect the reception of the radiation signal by the detector panel, so as to ensure that the detector has a good imaging effect and image quality. It should be noted that the interference signal transmission lines 210 added to the detector panel are simple in structure, easy to set up, and low in cost, which is conducive to the large-scale production and application of the detector panel.

[0046] Furthermore, each interference signal transmission line 210 is evenly distributed on the entire detector panel surface, so as to receive interference signals at various locations of the detector panel. Exemplarily, one interference signal transmission line 210 is provided for every two or three detection signal transmission lines 120.

[0047] It should be noted that, since the spectrum of various signals in the working environment of the detector is relatively wide, and the interference signal transmitted by the interference signal transmission line 210 is generally a high-frequency signal, if signals of other frequencies are transmitted together with the interference signal by the interference signal transmission line 210, errors will be generated in the process of signal subtraction to remove the interference signal, resulting in an inaccurate signal. Based on this, in order to improve the accuracy of the signal finally obtained by the detector, it is necessary to remove this part of the noise in the interference signal transmission line 210. In some optional implementations, such as Figure 5As shown, the interference receiving unit 200 further includes a high-pass filtering element 220 connected to the ground terminal of the interference signal transmission line 210. The high-pass filtering element 220 is used to filter out noise to prevent the interference signal transmission line 210 from transmitting noise together with the interference signal. Specifically, the high-pass filtering element 220 allows high-frequency signals to pass through while blocking the transmission of low-frequency signals. Since external electromagnetic radiation interference signals are usually high-frequency signals, the high-pass filtering element 220 can enable these electromagnetic radiation interference signals to pass through the interference signal transmission line 210 for transmission while filtering out other noise, thereby avoiding affecting the signal subtraction process of the detector.

[0048] Exemplarily, the high-pass filtering element 220 is a capacitor. Due to the physical characteristics of the capacitor, for high-frequency signals, the impedance of the capacitor is low, while for low-frequency signals, the impedance of the capacitor is high. Therefore, high-frequency signals can be transmitted through the capacitor, while low-frequency signals are blocked by the capacitor, thus achieving high-pass filtering. Further, the capacitance value of the capacitor is set based on the actual application requirements of the detector panel so that it can filter out most of the noise and retain the electromagnetic radiation interference signal. Specifically, those skilled in the art should know the specific setting method of the capacitance value, and this embodiment does not elaborate on it here.

[0049] Based on this, this embodiment provides a detector panel. The interference receiving unit 200 receives interference signals to combine with the signals received by the signal receiving unit 100, and subtract and cancel the interference signals received by the signal receiving unit 100, thereby avoiding the influence of the interference signals on the detection results of the detector. At the same time, since the interference receiving unit 200 has no influence on the signal receiving unit 100 receiving ray signals, it will not affect the imaging effect and image quality of the detector, and thus a better detection effect is achieved.

[0050] On the other hand, the present application also provides a detector for detecting an object or a human body through rays. Among them, the detector panel part of the detector is the detector panel as described above to achieve an anti-interference effect based on the detector panel and have a good imaging effect, which is beneficial to the practical application of the detector. Specifically, for the working principle and implementation manner of the detector to achieve an anti-interference effect and have a good imaging effect, please refer to the content of the foregoing detector panel, and this embodiment will not elaborate here.

[0051] Next, the technical solutions in the embodiments of the present application will be described in detail with reference to the accompanying drawings in the embodiments of the present application.

Both the signal receiving unit 100 and the interference receiving unit 200 transmit the received signals through the signal reading unit 300 to obtain detection signals and interference signals.

[0055] S200, perform subtraction calculation based on the detection signal and the interference signal to obtain an imaging signal.

[0056] Among them, the imaging signal refers to the signal used to form a detection image. Since the detection signal includes a ray signal and an interference signal, in order to avoid the influence of the interference signal on the detection result, by subtracting the interference signal from the detection signal, an imaging signal that excludes external interference can be obtained.
