Description

Technical Field

[0001] The present application relates to the technical field of radiation detection equipment, and in particular to an X-ray imaging system and a detection method. Background Art

[0002] X-ray imaging systems can produce X-ray images of the patient, and the results can provide doctors with insights into the patient's physical condition. Because X-rays are radioactive, X-ray imaging systems are typically placed in a shielded room. When an X-ray is required, the patient must first enter the room. The doctor then controls the X-ray system from outside the room to generate X-rays and complete the X-ray. Before the X-ray is taken, the patient must be positioned within the system and assume a posture appropriate to the area being examined.

[0003] However, most patients are unaware of their specific positioning and posture, making it difficult for doctors to communicate with them and provide guidance during X-rays outside the shielded room. Requiring doctors to enter the shielded room for guidance reduces their work efficiency. For example, current X-ray systems don't consider the specific needs of children, resulting in lower efficiency when performing X-rays on them. New technical solutions are needed to address this issue. Summary of the Invention

[0044] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and the related operations can be fully understood based on the description in the specification and the general technical knowledge in the art.

[0045] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0046] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0047] In the current solution, if the examinee is an adult, the doctor can directly guide the examinee to take the X-ray. The doctor usually guides the examinee with gestures outside the shielded room, or guides the examinee based on voice. However, it is difficult for the examinee to directly understand the doctor's meaning through gestures and voice. Therefore, the communication and guidance before the X-ray will take up a lot of time, which will affect the efficiency of the X-ray. However, when the examinee is a child, some children are prone to negative emotions such as fear, terror, and rejection after entering the unfamiliar shielded room, which may lead to non-cooperative behaviors such as crying and resistance, making it impossible to smoothly carry out the subsequent X-ray. At this time, it is usually necessary for the parents to slowly calm the child's emotions before the doctor can normally carry out the subsequent X-ray guidance. The process of calming the child will take a lot of time, thus affecting the efficiency of the X-ray.

[0048] In some embodiments of the present application, the multimedia device in the X-ray photography system includes a projector and a speaker, the speaker is used to play audio, and the projector is used to project images, wherein the image can intuitively show the relevant content to the examinee, and after being combined with the audio, it can efficiently convey relevant information to the examinee. At the same time, the multimedia device has a first mode and a second mode. When the controller controls the multimedia device to enter the first mode, the projector projects the first image, and / or the speaker plays the first audio to guide the examinee to position himself, thereby reducing the time occupied by communication and guidance during filming. When the controller controls the multimedia device to enter the second mode, the projector projects the second image, and / or the speaker plays the second audio, wherein the content of the second image is different from the first image, and the content of the second audio is different from the first audio. Therefore, in the second mode, it can play content that is different from the content that guides the examinee to position himself in the first mode, so that when the examinee is taking an X-ray, the X-ray photography system can convey content other than the X-ray test to the examinee, so as to alleviate the examinee's negative emotions caused by the X-ray, or make the examinee adapt to the shielded room environment, or make the examinee understand the X-ray process, which is conducive to the examinee's cooperation in subsequent X-rays, and it can also improve the efficiency of X-rays.

[0049] In some embodiments of the present application, while considering improving the efficiency of positioning guidance, the first mode of the multimedia device can efficiently guide the examinee to complete the relevant positioning, thereby improving filming efficiency. At the same time, while also considering improving the examinee's cooperation, the second mode of the multimedia device can play content different from the positioning guidance to ease the examinee's emotions, help the examinee adapt to the environment, or understand the filming process, so that the examinee can better cooperate, thereby improving filming efficiency.

[0050] In some embodiments, an X-ray imaging system is provided for generating X-rays to image a designated part of a subject and obtain an X-ray image of the designated part. Figure 1 and Figure 2 The X-ray imaging system includes a head 10, a detector 20, a multimedia device and a controller 30, which are described in detail below.

[0051] Please refer to Figure 2, the head 10 is used to generate X-rays. In some embodiments, the head 10 can be moved in two or three dimensions in space through mechanical structures such as a ceiling rail, so that it has the characteristics of a large mechanical travel range. In some embodiments, the head 10 can also be installed on a column, and the head 10 can move up and down on the column, and can also move forward and backward based on the forward and backward movement of the column. In some embodiments, an X-ray source and a beam limiter 12 are provided on the head 10. Among them, the X-ray source is used to generate X-rays, and the beam limiter 12 is used to limit the light field of the X-rays emitted by the X-ray source, so its main function is to constrain the X-rays, shield the scattered X-rays, and prevent X-ray leakage.

[0052] Please refer to Figure 2 The detector 20 includes a wired flat panel detector arranged vertically and a wired flat panel detector arranged horizontally, and the X-ray imaging system may be equipped with only one wired flat panel detector arranged vertically or one wired flat panel detector arranged horizontally, or may be equipped with both wired flat panel detectors. In some embodiments, the X-ray imaging system may also be equipped with a wireless flat panel detector. For example, the X-ray imaging system may be equipped with a wireless flat panel detector, or may be equipped with both a wireless flat panel detector and a wired flat panel detector 20. Regardless of whether it is a wired flat panel detector or a wireless flat panel detector, its function is to receive the X-rays generated by the head 10 and penetrating the human body to be imaged, and to obtain an imaging signal based on the received X-rays. The imaging signal is used to obtain an X-ray imaging image of the human body to be imaged.

[0053] Please refer to Figure 1 and Figure 2 , the multimedia device is used to input and output various multimedia information. In some embodiments, the multimedia device includes a projector 32 and a speaker 31, the projector 32 is used to project an image in a preset direction, and the speaker 31 is used to play audio, or to cooperate with the projector 32 to play audio corresponding to the image. In some embodiments, the projector 32 is mounted on the head 10 for projecting an image in the direction of the detector 20. In some embodiments, the projector 32 is mounted on the beam limiter 12 in the head 10. At this time, the projector 32 can project the image onto the imaging area of ​​the detector 20, and make the projection range at least include the imaging area, so that the projector 32 can not only project the image onto the detector 20, but also display the X-ray light field on the imaging area of ​​the detector 20 based on the projection range. In some embodiments, the speaker 31 can be mounted on the cross arm 14 of the head 10 for mounting the head 10.

[0054] In some embodiments, the multimedia device has a first mode and a second mode. When the multimedia device is in the first mode, the projector 32 is used to project a first image, and / or the speaker 31 is used to play a first audio to guide the patient in positioning. In this embodiment, positioning-related content can be played based on the first image and the first audio. When the patient sees the first image and hears the first audio, the patient can complete the corresponding positioning according to the positioning-related content. This eliminates the need for a doctor to enter a shielded room for guidance, and the patient can efficiently complete the positioning, thereby improving filming efficiency.

[0055] In some embodiments, the first image includes a third image and a fourth image, and the first audio includes a third audio and a fourth audio, wherein the third image is different from the fourth image, and the third audio is different from the fourth audio. In the first mode, the projector 32 projects the third image toward the detector 20, and / or the speaker 31 plays the third audio. At least after the handpiece 10 and / or the detector 20 reaches a designated position, the projector 32 projects the fourth image toward the detector 20, and / or the speaker 31 plays the fourth audio. In this embodiment, guiding the subject in positioning can be divided into at least two steps. First, when the subject enters the shielded room, the subject is guided to a preset position relative to the detector 20, i.e., the initial positioning. At this point, the projector 32 projects the third image, and the speaker 31 plays the third audio, to guide the subject in moving relative to the detector 20 and assuming the preset position. Furthermore, because the projector 32 projects the third image toward the detector 20, the subject easily notices the detector 20 and is attracted by the projection, moving toward the projection, thereby reaching the preset position. Next, after the subject reaches the preset position, they are guided to assume a preset posture relative to the detector 20. At this point, the projector 32 projects a fourth image, and the speaker 31 plays a fourth audio signal to guide the subject in aligning themselves with the detector 20 and assuming the preset posture, thus completing the final positioning. Furthermore, because the projector 32 projects the fourth image toward the detector 20, the subject can intuitively see how to position themselves relative to the detector 20, enabling efficient positioning.

[0056] In some embodiments, the third image and the third audio both include an introduction to the X-ray imaging system and the position requirements of the person being examined relative to the detector 20. In some embodiments, the equipment introduction may include an introduction to the working process of the X-ray imaging system, so that the person being examined can understand the position requirements relative to the detector 20, such as understanding what position can complete the inspection, which is helpful for the person being examined to reach the preset position. In some embodiments, the equipment introduction may also include an introduction to the components of the X-ray imaging system, so that the person being examined can quickly understand the X-ray imaging system, such as understanding what equipment is included and the name of each equipment, which is helpful for the person being examined to complete the relevant position requirements. In some embodiments, the third image may be played as a video or as an image.

[0057] In some embodiments, the fourth image and the fourth audio both include positioning teaching content and positioning guidance content. In some embodiments, the positioning teaching content can introduce the movements and requirements of each positioning, so that the person being tested can have a preliminary understanding of each positioning posture. In some embodiments, the positioning guidance content can include relevant positioning marking lines and positioning body position patterns. The person being tested can better complete the positioning based on the positioning marking lines and body position patterns. In some embodiments, the fourth image can be played in the form of a video or an image. Since the fourth image is directly projected onto the detector 20, it is convenient to assist the person being tested to complete the positioning.

[0058] In some embodiments, when the multimedia device is in the second mode, the projector 32 is used to project a second image, and / or the speaker 31 is used to play a second audio. The content of the second image is different from the first image, and the content of the second audio is different from the first audio. In this embodiment, other content can be played based on the second mode to guide the examinee in positioning, thereby diverting the examinee's attention through different playback content and avoiding causing significant negative emotions in the examinee due to filming. In some embodiments, the second image includes at least one of animated video content, movie video content, and short video content. For example, children's favorite animated videos can be played, such as interesting short videos or movie clips, to divert the examinee's attention and relieve their emotions. The second audio includes at least one of music audio content, story audio content, and audio content corresponding to each video content. For example, lighthearted songs or music can be played to soothe the examinee's emotions. After the examinee's emotions are relieved and soothed, the examinee can be more willing to cooperate to complete the subsequent positioning, thereby improving the efficiency of filming.

[0059] In the above embodiment, the first mode based on the multimedia device can assist the patient in quickly completing the positioning process, thereby reducing the doctor's inefficient guidance during the positioning process, thereby improving the efficiency of the filming. The second mode based on the multimedia device can ease the patient's emotions and improve their cooperation during the positioning process, which can also improve the efficiency of the filming.

[0060] Please refer to Figure 2 In some embodiments, the X-ray photography system further includes a camera 35, which is used to acquire images. In some embodiments, while the subject is being positioned based on the first mode of the multimedia device, the doctor can use the images acquired by the camera 35 to see the details of the subject's positioning in real time, such as the body position, whether the limb angles are appropriate, and whether the ionization chamber is aligned with the part to be photographed. If there is a need for adjustment, the subject can be further guided to complete the positioning through voice. In some embodiments, the camera 35 can also be installed on the beam limiter 12 in the head 10, so that the visualization range of the camera 35 at least includes the imaging area of ​​the detector 20 and the projection range of the projector 32, so that the corresponding image can be acquired for feedback to the doctor on the patient's current positioning status based on the detector 20, so that the doctor can determine whether the patient's positioning meets the shooting conditions outside the shielded room.

[0061] Please refer to Figure 1 In some embodiments, the X-ray imaging system may further include a human-computer interaction device, which may be mounted on the housing of the head 10. The human-computer interaction device is configured to output visual information and input information. For example, the human-computer interaction device may receive user input commands based on the touch display 16 and output visual information. In some embodiments, the human-computer interaction device may be used to control the specific content played by the multimedia device.

[0062] Please refer to Figure 2In some embodiments, the human-computer interaction device may further include a communication module 34, which is configured to receive input signals and output signals. In some embodiments, the communication module 34 may be implemented via a wired method such as an 485 communication module 34 or an Ethernet communication module 34, or via a wireless method such as a WiFi communication module 34 or a Bluetooth communication module 34. In some embodiments, the multimedia device further includes a microphone 33 for receiving voice input and converting it into a voice signal. The microphone 33 may be mounted on the cross arm 14 of the handpiece 10. In some embodiments, when the communication module 34 receives an input voice signal, it may play the voice signal via the speaker 31. When the microphone 33 receives the voice signal, it may output the voice signal to the terminal corresponding to the received voice signal, thereby enabling voice communication through the microphone 33, the speaker 31, and the communication module 34. For example, while the patient is being positioned using the first mode of the multimedia device, the doctor can provide real-time guidance to the patient based on this voice communication, and the patient can also provide real-time feedback on relevant issues, thereby further improving the efficiency of positioning.

[0063] The above is a brief description of the X-ray imaging system. The following is a detailed description of the process by which the X-ray imaging system completes filming.

[0064] First, the following explanation is given for subjects who do not need to relieve their emotions, such as the filming process for adults.

[0065] The X-ray imaging system is located in a shielded room. When a patient enters the shielded room, the doctor sends a first control signal to the X-ray imaging system via a terminal. The X-ray imaging system controller 30 controls the multimedia device to enter a first mode, controls the projector 32 to project a third image, and / or controls the speaker 31 to play a third audio. The doctor's terminal can be a workbench 50 outside the shielded room, a mobile terminal 40 in the doctor's hand, or a human-computer interaction device of the X-ray imaging system.

[0066] At this time, the person being tested reaches the preset position relative to the detector 20 according to the guidance of the third image and the third audio, thereby completing the preliminary positioning. Then, the head 10 and / or the detector 20 will initially reach a specified position according to the current part of the person being tested to be photographed, for example, whether the head 10 is facing the column-type detector 20 or the horizontal detector 20, and adjust the SID value, etc. After the head 10 and / or the detector 20 reaches the specified position, the controller 30 controls the projector 32 to project the fourth image, and / or controls the speaker 31 to play the fourth audio. At this time, the person being tested is positioned relative to the detector 20 according to the guidance of the fourth image and the fourth audio, and is in a preset posture, thereby completing the final positioning.

[0067] After the patient enters the shielded room, if the doctor is outside the room, the doctor can communicate with the patient at any time through the voice device on the workbench 50. For example, during the positioning process, the doctor can provide further guidance on positioning and communicate with the patient in other ways. At the same time, the camera 35 can capture the patient's current image, and the doctor can view this current image on the display on the workbench 50, determine whether the patient's positioning meets the requirements, and then provide feedback to the patient through the voice device.

[0068] In the above process, the projector 32, camera 35, microphone 33 and speaker 31 in the X-ray photography system form a multimedia system, which can facilitate the rapid positioning of the subject, thereby improving the efficiency of filming.

[0069] After the subject has completed the positioning, the doctor determines and confirms whether the current body position and machine status meet the requirements for filming, and confirms the exposure parameters (dose size). The doctor sends an imaging instruction based on the workbench 50, and the controller 30 responds to the imaging instruction and controls the head 10 to generate X-rays, and controls the detector 20 to receive the X-rays generated by the head 10 and penetrating the human body to be filmed, so as to obtain an imaging signal for generating an X-ray image, thereby completing the exposure. After the exposure is completed, an X-ray image is obtained and transmitted to the workbench 50. The doctor determines whether the X-ray image is qualified. If qualified, the doctor informs the patient by voice that the filming is completed and to leave the shielded room.

[0070] If the image is unqualified or the same subject has other body positions to be photographed, the subject will be informed to take the photo again, and a re-imaging instruction will be sent based on the workbench 50. The controller 30 will respond to the re-imaging instruction and control the multimedia device to re-enter the first playback mode to redirect the subject to position himself, and repeat the above process until the X-ray image is qualified or the same subject completes the photography of all body positions.

[0071] The following is an explanation for those who need to relieve their emotions, such as the filming process for children.

[0072] When the subject enters the shielded room, the doctor sends a second control signal to the X-ray imaging system via the terminal. The X-ray imaging system controller 30 then controls the multimedia device to enter the second mode, controls the projector 32 to project the second image, and / or controls the speaker 31 to play the second audio. For example, a cartoon audio or video clip or a children's song can be played to help the child eliminate their fear of the shielded room and prevent them from crying. After calming the child, the doctor sends the first control signal to the X-ray imaging system via the terminal, allowing the child to be positioned according to the normal adult-guided positioning process with the assistance of the parent.

[0073] In some embodiments, the doctor can also control the multimedia device based on the terminal to enter the first mode or the second mode at any time, and can also control the projector 32 to project the first image, the third image or the fourth image at any time, and control the speaker 31 to play the first audio, the third audio or the fourth audio at any time.

[0074] The following is an explanation for those who need to adapt to the environment or understand the filming process, such as the filming process for adults.
