Description

A medical X-ray fluoroscopy device, radiation protection device, method, and computer-readable storage medium. Technical Field

[0001] This invention relates to the technical field of intelligent medical information processing, and in particular to a medical X-ray fluoroscopy device, radiation protection device, method, and computer-readable storage medium. Background Technology

[0002] As people's demand for healthcare increases, X-ray fluoroscopy, a non-invasive method for observing changes in the morphology and function of organs from different angles, is an important medical examination widely used in various departments. However, because X-rays are short-wavelength electromagnetic waves, they can penetrate human tissue, causing physiological and biochemical changes in body fluids and cells, resulting in varying degrees of damage. Therefore, although the dose of medical X-rays to the human body each time is very small, radiation protection measures should be taken as much as possible to reduce the harm of X-rays and improve safety.

[0003] Existing medical X-ray fluoroscopy equipment, such as X-ray machines and CT scanners, do not have additional protective devices. In the actual examination process, patients mostly rely on holding a lead pad to cover their head, genitals, and other parts to achieve very low radiation protection requirements.

[0004] Chinese patent CN219323435U discloses a radiation-proof CT imaging scanning device that uses multiple radiation-proof panels to form a wrap-around protection for the human body. However, this solution uses a large area of ​​radiation-proof panels to shield the human body, which has the following drawbacks: First, it has a narrow range of application; it is difficult to expose only the organ being examined while shielding other organs that do not need to be examined during examinations of certain special organs. Second, it is not possible to make individualized adjustments for patients of different body types, or such adjustments are inconvenient, such as for people who are 1.9m and 1.6m tall. Third, shielding the human body requires a large number of radiation-proof panels, which is wasteful of materials and has high costs.

[0005] Therefore, there is an urgent need to develop a new medical X-ray fluoroscopy equipment, radiation protection device, method, and computer-readable storage medium. An adjustable light source-end protective device can solve the radiation protection problem at the X-ray emission end. This allows for convenient analysis of the patient's position and the area to be irradiated to determine the appropriate position, size, and shape of the light-blocking aperture, minimizing the impact of X-rays on areas not requiring examination. Furthermore, it allows for convenient individualized adjustments based on the patient's body shape, posture, organ position, and size. Moreover, it requires only a small area of ​​radiation-blocking material to protect the human body. By adjusting the position of the light source, the position of the protective plate, and the size of the light-emitting aperture, the radiation dose to the irradiated area can be controlled, thereby reducing radiation damage during fluoroscopy, improving the patient's fluoroscopy experience, and enhancing the safety, comfort, convenience, and economy of fluoroscopy examinations. Summary of the Invention

[0006] The main objective of this invention is to address the problems of inadequate, uncomfortable, and uneconomical radiation protection for patients in existing medical X-ray fluoroscopy equipment. This invention proposes a new medical X-ray fluoroscopy equipment, radiation protection device, method, and computer-readable storage medium. Through an adjustable light source-end protective device, the radiation protection problem can be solved from the X-ray emission end. It can easily analyze the appropriate position, size, and shape of the light-blocking aperture based on the patient's position and the areas to be irradiated, minimizing the impact of X-rays on areas not requiring examination. Furthermore, it allows for convenient individualized adjustments based on the differences in body shape, posture, organ position, and size among different patients. It requires only a small area of ​​radiation-blocking material to achieve human protection. Moreover, by adjusting the position of the light source, the position of the protective plate, and the size of the light-emitting aperture, the radiation dose to the irradiated area can be controlled, thereby reducing radiation damage during fluoroscopy, improving the patient's fluoroscopy experience, and enhancing the safety, comfort, convenience, and economy of fluoroscopy examinations.

[0007] To achieve the above objectives, the present invention provides a medical X-ray fluoroscopy device, the device comprising an X-ray generator, an information acquisition module, an analysis and calculation module, and an adjustable light source end protection device.

[0008] The X-ray generator is used to generate X-rays;

[0009] The information acquisition module is used to acquire information about the areas of the patient that need to be irradiated and the patient's location.

[0010] The adjustable light source end protection device includes a protective plate and an adjustment device. The protective plate has a light outlet hole, and the adjustment device is used to adjust the position of the protective plate and the position, size, and shape of the light outlet hole. The adjustable light source end protection device is located at the light outlet of the X-ray generator. The X-rays generated by the X-ray generator pass through the light outlet hole and irradiate the part of the patient that needs to be irradiated.

[0011] The analysis and calculation module is electrically connected to the information acquisition module and the adjustment device. The information acquisition module acquires the part of the patient to be irradiated and the patient's position information and transmits it to the analysis and calculation module. The analysis and calculation module analyzes and calculates the appropriate position of the protective plate and the position, size and shape of the light outlet based on the part of the patient to be irradiated and the patient's position information and transmits it to the adjustment device. The adjustment device adjusts the position of the protective plate and the position, size and shape of the light outlet according to the analysis and calculation results.

[0012] As described above, in the medical X-ray fluoroscopy equipment, the information acquisition module includes a data interface and / or an image acquisition device. The data interface is used to acquire the parts of the patient that need to be irradiated, and the image acquisition device is used to acquire the patient's position information, which includes the patient's body position and the patient's body posture.

[0013] As described above, in the medical X-ray fluoroscopy equipment, the information acquisition module is further used to acquire individualized patient information. This individualized patient information is used to analyze and evaluate the specific location and shape of the area to be irradiated on the patient's body. The analysis and calculation module analyzes the specific location and shape of the area to be irradiated on the patient's body based on the individualized patient information. Then, based on the area to be irradiated, the patient's location information, and the specific location and shape of the area to be irradiated on the patient's body, it analyzes and calculates the appropriate position of the protective plate and the position, size, and shape of the light-emitting hole, which are then transmitted to the adjustment device. The adjustment device adjusts the position, size, and shape of the protective plate and the light-emitting hole according to the analysis and calculation results.

[0014] The medical X-ray fluoroscopy equipment described above also includes a pre-acquisition device, which is used to collect individualized information of the patient. By analyzing the individualized information of the patient, the device can accurately analyze the specific areas that need to be irradiated, including lesions, trauma sites, surgical sites, implanted organs / materials / devices, and suspicious / key locations, thereby further narrowing down the area that needs to be irradiated.

[0015] The medical X-ray fluoroscopy device described above further includes the ability to control the radiation dose of the irradiated area by adjusting the position of the X-ray source, the position of the protective plate, and the size of the light outlet.

[0016] The medical X-ray fluoroscopy device described above further includes a dose-adjusting lens module, which comprises an optical lens and a radiation shield. The dose-adjusting lens module is located between the X-ray generator and the adjustable light source end protection device, and is used to change the propagation direction of X-rays to control the radiation dose of the irradiated area.

[0017] As described above, in the medical X-ray fluoroscopy equipment, when the light outlet of the X-ray generator rotates, the information acquisition module acquires the rotation speed and acceleration of the light outlet of the X-ray generator. The analysis and calculation module analyzes and calculates the suitable position, size, and shape of the light outlet at different times based on the rotation speed and acceleration of the light outlet of the X-ray generator, the part of the patient to be irradiated, the patient's position information, and the specific position and shape of the part to be irradiated on the patient's body. This information is then transmitted to the adjustment device, which adjusts the position, size, and shape of the light outlet according to the analysis and calculation results.

[0018] The present invention also provides a radiation protection device for medical X-ray fluoroscopy equipment, the radiation protection device comprising: an information acquisition module, an analysis and calculation module, and an adjustable light source end protection device.

[0019] The information acquisition module is used to acquire information about the areas of the patient that need to be irradiated and the patient's location.

[0020] The adjustable light source end protection device includes a protective plate and an adjustment device. The protective plate has a light outlet hole, and the adjustment device is used to adjust the position of the protective plate and the position, size, and shape of the light outlet hole. The adjustable light source end protection device is located at the light outlet of the X-ray generator. The X-rays generated by the X-ray generator pass through the light outlet hole and irradiate the part of the patient that needs to be irradiated.

[0021] The analysis and calculation module is electrically connected to the information acquisition module and the adjustment device. The information acquisition module acquires the part of the patient to be irradiated and the patient's position information and transmits it to the analysis and calculation module. The analysis and calculation module analyzes and calculates the appropriate position of the protective plate and the position, size and shape of the light outlet based on the part of the patient to be irradiated and the patient's position information and transmits it to the adjustment device. The adjustment device adjusts the position of the protective plate and the position, size and shape of the light outlet according to the analysis and calculation results.

[0022] As described above, the radiation protection device can also be installed on radiotherapy equipment for precise control of the radiation irradiation area and radiation dose of the radiotherapy equipment.

[0023] The present invention also provides a method of using the medical X-ray fluoroscopy device as described above, the method comprising:

[0024] Obtain information on the areas of the patient that need irradiation and the patient's location;

[0025] Based on the patient's location and the area requiring irradiation, the appropriate position, size, and shape of the protective plate and the light outlet are calculated.

[0026] Adjust the position, size, and shape of the protective plate and the light outlet according to the analysis and calculation results.

[0027] A computer-readable storage medium storing a computer program, characterized in that: when the computer program is executed by a processor, it implements the steps of the method of using the medical X-ray fluoroscopy device as described above.

[0028] This invention discloses a medical X-ray fluoroscopy device, radiation protection device, method, and computer-readable storage medium. The device includes an X-ray generator, an information acquisition module, an analysis and calculation module, and an adjustable light source end protective device. The method includes: acquiring information about the patient's irradiation site and patient position; analyzing and calculating the appropriate position of the protective plate and the position, size, and shape of the light outlet based on the patient's irradiation site and position information; and adjusting the position of the protective plate and the position, size, and shape of the light outlet according to the analysis and calculation results. This invention's medical X-ray fluoroscopy device, radiation protection device, method, and computer-readable storage medium, through the adjustable light source end protective device, solves the radiation protection problem from the X-ray emission end, minimizing the impact of radiation on areas not requiring examination; facilitating individualized adjustments; reducing material requirements; and allowing control of the radiation dose in the irradiated area by adjusting the position of the light source, the position of the protective plate, and the size of the light outlet. Control of the radiation dose in the irradiated area can also be achieved through the lens module, thereby improving the safety, comfort, convenience, and economy of fluoroscopy examinations.

[0033] Figure 5 is a flowchart of the method of using the medical X-ray fluoroscopy device according to the third embodiment of the present invention. Detailed Implementation

[0034] To further illustrate the technical means and effects adopted to achieve the intended purpose of this application, the specific implementation methods of this application will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely for explaining this application and are not intended to limit this application.

[0035] The first embodiment of the present invention is illustrated in Figure 1. Figure 1 is a schematic diagram of a medical X-ray fluoroscopy device according to the first embodiment of the present invention. As shown in the figure, the medical X-ray fluoroscopy device of the present invention includes an X-ray generator 11, an information acquisition module 12, an analysis and calculation module 13, and an adjustable light source end protection device 14.

[0036] The X-ray generator 11 is used to generate X-rays. It mainly consists of an X-ray tube, a power supply, and a control circuit. The X-ray tube is composed of a cathode filament, an anode target, and a vacuum glass tube. The power supply can be divided into a high-voltage power supply and a filament power supply. The filament power supply is used to heat the filament. The high-voltage output terminal of the high-voltage power supply is clamped at both ends of the cathode filament and the anode target, respectively, to provide a high-voltage electric field that accelerates the active electrons on the filament towards the anode target, forming a high-speed electron stream. After bombarding the anode target surface, X-rays are generated.

[0037] The information acquisition module 12 is used to acquire information about the areas of the patient requiring irradiation and the patient's location. The information acquisition module 12 may include a data interface / input device. The data interface can connect to the HIS system, hospital database, health service department server, mobile terminal system, or other systems or servers capable of acquiring the required information, for acquiring the areas of the patient requiring irradiation. The areas of the patient requiring irradiation can be obtained from the following sources: the user's examination report, test report, medical orders, medical records / electronic medical records, payment slips, payment records, etc. The input device can be a mouse, keyboard, voice input device, or other input device, used by the patient or medical personnel to input information, such as the areas of the patient requiring irradiation.

[0038] The information acquisition module 12 may further include an image acquisition device, which may be a camera / imaging device, used to acquire patient location information, including the patient's body position and body posture. The information acquisition module 12 may include two or more cameras / imaging devices, which acquire images of the patient from different angles to obtain the patient's body posture, and calculate the patient's body position based on multi-angle image ranging or other methods.

[0039] The adjustable light source end protection device 14 includes a protective plate and an adjustment device. The protective plate has a light-emitting hole, and the adjustment device is used to adjust the position of the protective plate and the position, size, and shape of the light-emitting hole. The adjustable light source end protection device is located at the light-emitting port of the X-ray generator. The X-rays generated by the X-ray generator pass through the light-emitting hole and irradiate the part of the patient that needs to be irradiated. In this embodiment, the position of the protective plate refers to the relative position of the protective plate and the X-ray generator 11, and the position of the light-emitting hole refers to the position of the light-emitting hole on the protective plate. Since the X-rays are emitted from the X-ray generator, pass through the light-emitting hole, and irradiate the patient. Therefore, the position of the light exit aperture, i.e., its position on the protective plate, can control the position of the X-ray on the patient. For example, moving the light exit aperture to the left will shift the area of ​​the X-ray on the patient to the left accordingly. The shape of the light exit aperture can control the outer contour of the area irradiated by the X-ray on the patient. For example, when taking a chest X-ray, the shape of the light exit aperture can be similar to the shape of the lung. The size of the light exit aperture can control the size of the area irradiated by the X-ray on the patient. For example, if a larger area needs to be irradiated, the size of the light exit aperture can be increased.

[0040] The analysis and calculation module 13 is electrically connected to the information acquisition module 12 and the adjustment device of the adjustable light source end protection device 14. The information acquisition module 12 acquires the part of the patient to be irradiated and the patient's position information (including posture) and transmits it to the analysis and calculation module 13. The analysis and calculation module 13 analyzes and calculates the appropriate position of the protective plate and the position, size and shape of the light outlet hole according to the part of the patient to be irradiated and the patient's position information, and transmits it to the adjustment device. The adjustment device adjusts the position of the protective plate and the position, size and shape of the light outlet hole according to the analysis and calculation results.

[0041] The medical X-ray fluoroscopy device of the present invention, by acquiring the patient's location information and the area to be irradiated, can estimate the specific location and shape (shape and area) of the area to be irradiated on the patient's body based on anthropology. Then, it analyzes and calculates the position, size, and shape of the protective plate of the adjustable light source end protective device and the appropriate position, size, and shape of the light outlet hole of the protective plate. By adjusting the position, size, and shape of the protective plate and the light outlet hole according to the analysis and calculation results, the X-rays pass through the adjustable light source end protective device 14 and irradiate the area to be irradiated on the patient, reducing the unnecessary X-ray irradiation damage to the patient.

[0042] The medical X-ray fluoroscopy device of the present invention, in addition to estimating the specific location and shape of the area to be irradiated on the patient's body based on the patient's location information, can also better assess the specific location and shape of the area to be irradiated on the patient's body by acquiring the patient's individualized information. The information acquisition module 12 is also used to acquire the patient's individualized information, which is used to analyze and evaluate the specific location and shape of the area to be irradiated on the patient's body. The analysis and calculation module 13 first analyzes the specific location and shape of the area to be irradiated on the patient's body based on the patient's individualized information, and then analyzes and calculates the appropriate position of the protective plate and the position, size, and shape of the light outlet based on the area to be irradiated, the patient's location information, and the specific location and shape of the area to be irradiated on the patient's body. This information is transmitted to the adjustment device, which adjusts the position of the protective plate and the position, size, and shape of the light outlet according to the analysis and calculation results. The above-mentioned position also needs to consider the influence of the movement of the X-ray machine / patient's body on the position in the prior art. When the position of the X-ray machine / patient's body changes, the calculated appropriate position of the protective plate also needs to be adjusted accordingly.

[0043] In this invention, the patient's individualized information is used to assess the specific location and shape of the areas requiring irradiation on the patient's body. This information may include: the patient's height, weight, body type, characteristics of various body parts (shape, size, and thickness of each part; shape, size, and location of each organ; location, shape, and size of implanted materials / devices; location, shape, and size of trauma / surgical sites; location, shape, and size of lesions; location, shape, and size of suspicious areas, etc.), medical history, surgical history, and historical X-ray / CT / MRI / ultrasound examination data. The sources of the patient's individualized information may include: user personal information databases, health records, medical orders, medical records, electronic medical records, medical institution information systems, medical records, treatment records, examination records, assessment reports, consultation records, investigation records, treatment records / plans, exercise records / plans, rehabilitation records / plans, test / examination reports, surgical plans / records, and health records / plans. It may also be obtained from various wearable devices, sensors, electronic devices, surgical robots, intelligent monitoring / monitoring systems, intelligent detection / analysis devices, etc., or from analysis of information related to the user's race / family / region / age / marital status / fertility.

[0044] In this invention, a personalized 3D model database can be established to better obtain individualized patient information and assess the specific location and shape of the areas requiring irradiation on the patient's body. The personalized 3D model database includes personalized 3D medical imaging models created for different patients, encompassing various parts of the human body such as the head, limbs, and trunk; various organs such as the liver, lungs, kidneys, spleen, pancreas, bladder, and rectum; skeletal structures such as ribs, vertebrae, pelvis, femur, tibia, ribs, skull, mandible, and hand and foot bones; body structural parts such as the top of the liver, aortic arch, and pubic symphysis; and internal lesions or nodules such as liver and kidney injuries, lung nodules, lymph nodes, trauma sites, transplanted organs, implanted materials / devices, and surgical sites. The personalized 3D medical imaging model can be a medical imaging model created for different subjects from different positions, angles, and cross-sections. The medical image model can be established based on the size, shape, color, dimensions, and structure of the object, or by acquiring a large number of medical images and then analyzing them through big data analysis to create the model. The model can also be established through a combination of the above methods. In this invention, the model can be a digital model or other types of models. It can be a vector model or a non-vector model; this invention is not limited in this regard. The patient-specific 3D model database can be stored on a network server, and the medical X-ray fluoroscopy device of this invention obtains it by connecting to the network server through the information acquisition module 12. Alternatively, the medical X-ray fluoroscopy device of this invention may also include a database module, which stores the patient-specific 3D model database. When it is necessary to obtain patient-specific information, the information acquisition module 12 directly obtains the patient's individualized information from the database module.

[0045] The medical X-ray fluoroscopy device of the present invention may further include a pre-acquisition device, which is used to pre-acquire individualized information of the patient, and may be: ultrasound, camera, infrared image acquisition device, ultraviolet image acquisition device, radar, etc. By analyzing the patient's individualized information, the specific areas to be irradiated within the patient's required irradiation sites can be precisely analyzed, including lesions, wound sites, surgical sites, implanted organs / materials / devices, and suspicious / key locations. During patient examinations / follow-up examinations, the area requiring irradiation can be further narrowed, reducing the irradiation of areas that do not need to be examined and reducing the radiation damage suffered by the patient. In the present invention, the patient's surgical site may include intraoperative fluoroscopy-assisted surgery or postoperative fluoroscopy for recovery examination of the surgical site.

[0046] The medical X-ray fluoroscopy device of the present invention includes an adjustable light source end protection device 14 comprising an aperture through which X-rays pass, irradiating the patient. This aperture is adjustable, and the area of ​​the patient's body irradiated by the X-rays can be controlled by adjusting its position, size, and shape. Figures 2a and 2b are schematic diagrams of the adjustable light source end protection device. As shown in Figure 2a, the adjustable light source end protection device 14 includes a protective plate 140 and an adjustment device. The protective plate 140 has a light-emitting hole 141 and is provided with one or more slide rails 142 located on both sides of the light-emitting hole 141, with multiple slide rails 142 arranged side-by-side on each side. The adjustment device includes a drive motor and one or more shielding strips 143. Each shielding strip 143 has a slider, and the drive motor can drive the slider to move on the slide rail 142. Each slide rail 142 can have a shielding strip 143 that moves on the slide rail 142 via a slider. Both the protective plate 140 and the shielding strip 143 can serve to block X-rays and prevent radiation.

[0047] As shown in Figure 2b, the portion of the light aperture 141 that allows X-rays to pass through (the portion not blocked by the shielding strips 143) can be adjusted by changing the position of each shielding strip 143. The smaller the height of each shielding strip and the more shielding strips there are, the more precisely the shape, position, and size of the portion that allows X-rays to pass through can be adjusted. For ease of drawing, Figure 2b shows only four shielding strips on each side; however, dozens or even more shielding strips can be set on each side as needed. Moving all shielding strips 143 one unit length to the left or right is equivalent to moving the X-ray passage one unit length in that direction. If it is necessary to move the X-ray passage upwards (or downwards), the position of each row of shielding strips can be adjusted to match the position of the row above (or below) it. In Figures 2a and 2b, the slide rail and the shielding strip are set on the left and right sides of the light outlet hole 141. Alternatively, the slide rail and the shielding strip can be set on the upper and lower sides of the light outlet hole 141. This can also adjust the position, size, and shape of the hole through which X-rays can pass by the adjustable light source end protection device 14. The specific method is similar to that of setting it on the left and right sides, and will not be described in detail here.

[0048] In this invention, the shielding strip 143 can also be a component in the form of a shielding plate or a shielding block, and the slide rail 142 can also be a telescopic bracket or a rotating shielding blade, etc., to realize the adjustable position, size, and shape of the window through which X-rays can pass. This invention does not limit this. For example, the adjustable light source end protection device 14 can also be implemented using a grating structure, which can be composed of multiple adjustable blades with X-ray protection function. The blades can be adjusted in extension angle and position as needed, so that multiple blades can form a light outlet with a suitable position, shape, and size. In this invention, the protective plate can be implemented in various ways that can change shape and size, such as a plastic flexible baffle.

[0049] In this invention, the adjustable light source end protective device 14 can also be a device with other structures, such as a protective plate with a suitable shape / size of light-emitting hole that can be replaced according to the shape of the irradiated part required by the user. The distance between the protective plate and the light source can be adjusted by adjusting the position of the protective plate, so as to control the actual position, shape and size of the X-ray irradiation on the relevant part of the human body. As long as it can achieve the goal of including a hole through which X-rays can pass and irradiate the patient, and the position, size and shape of the hole through which X-rays can pass are adjustable, this invention does not limit it.

[0050] The medical X-ray fluoroscopy device of the present invention can further control the area of ​​X-ray irradiation on the patient's body by adjusting the position of the protective plate and the position, size, and shape of the adjustment hole. The adjustment device of the adjustable light source end protective device 14 can also include an adjustment component for adjusting the position of the protective plate. The adjustment component can be a telescopic rod, with one end connected to the X-ray generator and the other end connected to the protective plate. The relative position of the protective plate and the X-ray generator can be adjusted via the telescopic rod. Adjusting the position of the protective plate can adjust both the distance between the light-emitting hole on the protective plate and the fluoroscopic light source, and the distance between the light-emitting hole and the patient. Compared to existing devices where the protective device is located at the human body end, this allows for more flexible control of the area of ​​X-ray irradiation on the patient's body. In the medical X-ray fluoroscopy device of the present invention, the adjustment device of the adjustable light source end protective device 14 can adjust the position, size, and shape of the window through which X-rays pass on the protective plate via components such as a slide rail 142 and a shielding strip 143, and then adjust the position of the protective plate via adjustment components such as a telescopic rod.

[0051] The medical X-ray fluoroscopy device of the present invention can also control the radiation dose of the irradiated area by adjusting the position of the X-ray source, the position of the protective plate, and the size of the light outlet. The aforementioned positions refer to the relative positions of the source, the protective plate, and the patient's irradiated area. When it is necessary to reduce the radiation dose of the irradiated area, the X-ray generator can be moved away from the patient (adjusting the distance between the source and the body), while simultaneously adjusting the position of the protective plate to increase the distance between the protective plate and the patient while keeping the distance between the protective plate and the X-ray generator unchanged. The size of the light outlet is also adjusted to be correspondingly smaller, but the shape remains unchanged. At this time, the area of ​​the patient's body irradiated by X-rays remains unchanged. However, because the X-ray generator is moved away from the patient, the proportion of X-rays irradiating the patient through the light outlet located on the protective plate decreases compared to the total X-rays emitted by the X-ray generator. If the X-rays emitted by the X-ray generator remain unchanged, then the amount of X-ray radiation received by the patient's body area decreases. When it is necessary to increase the radiation dose of the irradiated area, the opposite operation is performed. This achieves convenient and quick control of the radiation dose of the patient's irradiated area without adjusting the X-ray emission parameters of the X-ray generator.

[0052] The medical X-ray fluoroscopy device of the present invention can also change the direction of X-rays through lenses, thereby achieving more efficient control of radiation dose. The medical X-ray fluoroscopy device may further include a dose-adjusting lens module, which includes an optical lens and a radiation shield. The dose-adjusting lens module is located between the X-ray generator and the adjustable light source end protection device, and is used to change the propagation direction of X-rays to achieve control of the radiation dose in the irradiated area.

[0053] Figure 3 is a schematic diagram of radiation dose control via a dose-adjusting lens module. As shown in Figure 3, the dose-adjusting lens module 15 is located between the X-ray generator 11 and the adjustable light source end shielding device 14. A portion of the X-rays emitted from the X-ray generator 11 pass through the dose-adjusting lens module 15, while the remaining X-rays are blocked by the radiation shielding plate of the dose-adjusting lens module 15 and cannot irradiate the adjustable light source end shielding device 14. The change in the direction of the X-rays via the dose-adjusting lens module 15 results in a larger irradiation angle, allowing a portion of the X-rays to pass through the light outlet of the adjustable light source end shielding device 14 and irradiate the area of ​​the patient's body that needs irradiation. Because the change in the direction of the X-rays via the dose-adjusting lens module 15 results in a larger irradiation angle and a larger irradiated area, the intensity and radiation dose per unit area are lower than when the X-rays directly irradiate the area of ​​the patient's body without the dose-adjusting lens module 15. Therefore, the medical X-ray fluoroscopy equipment of the present invention, through the dose-adjusting lens module 15, can reduce the radiation dose to the irradiated area. Conversely, if the dose-adjusting lens module 15 alters the direction of the X-rays, resulting in a smaller irradiation angle and a smaller irradiated area, then an increase in the radiation dose to the irradiated area can be achieved. Since the dose-adjusting lens module can both reduce and increase the radiation dose to the irradiated area, it can be used to control the radiation dose in the irradiated area.

[0054] In this invention, the dose-adjusting lens module 15 adjusts the direction of X-rays, thereby adjusting the irradiable area and consequently the intensity and radiation dose of X-rays per unit area, thus controlling the radiation dose of the irradiated area. The dose-adjusting lens module 15 can be a single concave or convex lens, or a group of lenses working together to achieve the goal of changing the direction of X-rays. The specific configuration of the dose-adjusting lens module 15 can be determined by an artificial intelligence program based on the requirements of the direction adjustment goal.

[0055] In this invention, the lens of the dose-adjusting lens module 15 is made of a uniform, impurity-free material, ensuring that the X-rays passing through the dose-adjusting lens module 15 propagate normally with a uniform optical path free from abnormal deformation. If slight abnormal deformation of the propagating optical path occurs due to lens non-uniformity, resulting in distortion of the fluoroscopic image, this can be resolved through distortion compensation via adjustment. The problematic lens module can be first installed on a medical X-ray fluoroscopy device to acquire a blank fluoroscopic image. A distortion compensation function can then be calculated based on the specific parameters of the blank fluoroscopic image. Therefore, in actual use, for each fluoroscopic image, the image data is compensated using the compensation function to counteract the image distortion caused by the problematic lens.

[0056] The medical X-ray fluoroscopy device of the present invention may include multiple dose-adjusting lens modules 15. When the change in radiation dose to the irradiated area is too large, requiring a significant change in the direction of X-rays through a single dose-adjusting lens module 15, which is not feasible or easy to achieve due to the actual environment of the fluoroscopy site, multiple dose-adjusting lens modules 15 can be used in combination to achieve multi-level progressive adjustment. Each dose-adjusting lens module 15 adjusts only a suitable range, and the final adjustment target is achieved through multiple adjustments.

[0057] The medical X-ray fluoroscopy device of this invention can be a medical X-ray machine, a CT scanner, or other medical fluoroscopy equipment that emits radiation. A medical X-ray machine simply irradiates the body with X-rays from one direction to acquire one or a few images. A CT scanner, on the other hand, performs a circular scan around a specific part of the body. By irradiating the body with X-rays emitted from an X-ray tube at different angles, and then using a computer to perform complex mathematical reconstruction of this multi-angle information, a tomographic image of that part of the body is obtained.

[0058] When the medical X-ray fluoroscopy device of the present invention is a medical X-ray machine, the information acquisition module 12 can acquire the patient's irradiation site and patient position information. The patient position information includes the patient's body position and posture. The patient's posture can be obtained by acquiring images of the patient from different angles, and the patient's body position can be calculated based on a multi-angle image ranging method. Alternatively, individualized patient information can be acquired to analyze and evaluate the specific position and shape of the irradiation site on the patient's body. Then, the analysis and calculation module 13 analyzes and calculates the appropriate position, size, and shape of the light exit aperture based on the irradiation site, the patient position information, and the specific position and shape of the irradiation site on the patient's body.

[0059] Specific methods could be:

[0060] Establish a coordinate system. Obtain the position coordinates of the X-ray source (i.e., the X-ray generator's output port) and the position coordinates of the output aperture 141. The positions of the X-ray source and the output aperture 141 are controllable by medical X-ray machines and are known. Current conventional X-ray machines can even move the X-ray source directly towards the area to be irradiated. The medical X-ray fluoroscopy device of this invention, because the X-ray irradiation range can be controlled by the adjustable light source end protection device 14, allows the X-ray source (i.e., the X-ray generator's output port) to be moved directly towards the area to be irradiated, or it can remain stationary. The X-ray emission angle can also be adjusted by adding a collimator or other devices that can adjust the X-ray emission angle to the X-ray generator. In this invention, the medical X-ray fluoroscopy device can also control the X-ray irradiation range by adjusting the position and angle of the X-ray source and by adjusting the position, size, and shape of the output aperture window through the adjustable light source end protection device 14, thus preventing unnecessary areas from being irradiated and reducing radiation damage to the patient.

[0061] The specific coordinates of the areas on the patient's body requiring irradiation are obtained. Since the patient's location and the area requiring irradiation are known, and the specific location and shape of the irradiated area on the patient's body can be analyzed and assessed, the specific coordinates of the irradiated area can be obtained. Because the area requiring irradiation has a certain volume and is not a single point, the coordinates of the irradiated area represent a range.

[0062] Then, based on the specific coordinates of the light source, the light exit aperture, and the area of ​​the patient to be irradiated, the position, size, and shape of the window portion of the light exit aperture that allows X-rays to pass through can be calculated using geometric principles. Then, based on the position, size, and shape of the window portion of the light exit aperture that allows X-rays to pass through, the positions of each shielding strip 143 of the adjustable light source end protective device 14 can be calculated. The appropriate position, size, and shape of the window portion of the light exit aperture that allows X-rays to pass through can then be adjusted according to the calculation results.

[0063] Alternatively, an iterative method can be used to obtain the position, size, and shape of the window portion through which X-rays can pass. The specific method is as follows: 1. Obtain the current position, size, and shape of the window portion; 2. Calculate whether each position of the patient's organ to be irradiated under the current window is unobstructed. If there is obstruction, increase the window size and repeat step 2; if there is no obstruction, proceed to the next step; 3. Reduce the window size and calculate whether each position of the patient's organ to be irradiated under the reduced window size is obstructed. If there is no obstruction, repeat step 3; if there is obstruction, return the position, size, and shape of the window portion before the current reduction.

[0064] When the medical X-ray fluoroscopy device of the present invention is a CT scanning device, the X-ray tube performs a circular rotational scan around the area of ​​the patient to be irradiated. X-rays are emitted from the X-ray tube at different angles to irradiate the human body, and then a computer performs complex mathematical reconstruction on this multi-angle information to obtain a tomographic image of that part of the body. The information acquisition module 12 can acquire the rotational speed and acceleration of the X-ray generator's output port. The analysis and calculation module 13, based on the rotational speed and acceleration of the X-ray generator's output port, the area of ​​the patient to be irradiated, the patient's position information, and the specific position and shape of the area to be irradiated on the patient's body, analyzes and calculates the suitable position, size, and shape of the output aperture at different times, and transmits this information to the adjustment device. The adjustment device adjusts the position, size, and shape of the output aperture according to the analysis and calculation results.

[0065] Firstly, since medical X-ray fluoroscopy equipment is a CT scanning device, the X-ray tube rotates in a ring around the area of ​​the patient that needs to be irradiated. Therefore, the portion of the light outlet that allows X-rays to pass through can actually be a line, with a width equal to the width of a shielding strip 143, and a length that is adjusted according to the different irradiation range required at different rotation positions.

[0066] Since the rotation speed and acceleration of the X-ray tube (i.e., the X-ray generator's output port) are set by the CT scanning equipment and are known, the direction of X-ray irradiation at any given moment is also known. Furthermore, analysis can determine the specific location and shape of the area to be irradiated on the patient's body, thus allowing for the determination of the area to be irradiated in any X-ray direction. The required length of the output port opening in each irradiation direction can then be calculated. Based on the relationship between the X-ray generator's output port rotation position and time, the relationship between the length of the output port opening and time can also be obtained. The calculated results are transmitted to the adjustment device, which adjusts and controls the output port opening according to these results. This allows for convenient adjustment of the X-ray irradiation range, improving the safety, comfort, convenience, and economy of fluoroscopy examinations.

The adjustable light source end protection device is located at the light outlet of the X-ray generator.

[0070] The analysis and calculation module 13 is electrically connected to the information acquisition module 12 and the adjustment device of the adjustable light source end protection device 14. After the information acquisition module 12 acquires the part of the patient to be irradiated and the patient's position information, it transmits it to the analysis and calculation module 13. The analysis and calculation module 13 analyzes and calculates the appropriate position of the protective plate and the position, size and shape of the light outlet hole according to the part of the patient to be irradiated and the patient's position information, and transmits it to the adjustment device. The adjustment device adjusts the position of the protective plate and the position, size and shape of the light outlet hole according to the analysis and calculation results.
