Description

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 genitals 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 protection 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 X-ray exposure to areas not requiring examination. Furthermore, it allows for convenient individualized adjustments based on the patient's body shape, organ location, size, and other unique characteristics. Moreover, it requires only a small area of ​​radiation-proof material to achieve human protection, thereby reducing radiation damage during fluoroscopy, improving the patient's fluoroscopy experience, and enhancing the safety, comfort, convenience, and cost-effectiveness 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 protection device, the radiation protection problem can be solved at 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 X-ray exposure to areas not requiring examination. Furthermore, it allows for convenient individualized adjustments based on the differences in body shape, organ location, size, and shape among different patients. Moreover, it requires only a small area of ​​radiation protection material to achieve human protection, 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.

[0030] Figure 4 This is a flowchart illustrating the method of using the medical X-ray fluoroscopy device according to the third embodiment of the present invention. Detailed Implementation

[0031] 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.

[0032] The first embodiment of the present invention is described below. Figure 1 . Figure 1 This is a schematic diagram of a medical X-ray fluoroscopy device according to a 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.

[0033] 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.

[0034] 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, 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 sources such as the user's examination reports, test reports, 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.

[0035] The information acquisition module 12 may further include a camera / imaging device for acquiring patient location information, which includes the patient's body position and posture. The information acquisition module 12 may include two or more cameras / imaging devices to acquire images of the patient from different angles, obtain the patient's posture, and calculate the patient's body position based on multi-angle image ranging or other methods.

[0036] The adjustable light source end protection device 14 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, 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.

[0037] 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 position, size and shape of the light outlet 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, size and shape of the light outlet according to the analysis and calculation results.

[0038] The medical X-ray fluoroscopy device of the present invention, by acquiring the patient's required irradiation area and patient position information, can estimate the specific position and shape of the patient's required irradiation area on the patient's body based on anthropology. Then, it analyzes and calculates the suitable position, size, and shape of the light outlet hole of the adjustable light source end protective device 14. The adjustment device adjusts the light outlet hole to the suitable position, size, and shape according to the analysis and calculation results, so that X-rays pass through the adjustable light source end protective device 14 and irradiate the patient's required irradiation area, reducing the unnecessary X-ray irradiation damage to the patient.

[0039] 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 analyzes and calculates the suitable position, size, and shape of the light-emitting aperture based on the patient's location information, the specific location and shape of the area to be irradiated on the patient's body, and transmits this information to the adjustment device. The adjustment device adjusts the position, size, and shape of the light-emitting aperture according to the analysis and calculation results. The position of the light-emitting aperture includes the distance, position, and angle of the light-emitting aperture relative to the patient or the area to be irradiated.

[0040] In this invention, the patient's individualized information is used to assess the specific location and shape of the areas on the patient's body that need irradiation. This information may include: the patient's height, weight, body type, characteristics of various body parts, medical history, surgical history, and historical X-ray / CT / MRI / ultrasound examination data. The sources of this 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, assessment reports, consultation records, survey 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 the analysis of information related to the user's race / family / region / age / marital status / fertility.

[0041] 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 image models created for different patients, encompassing various human 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 lesions or nodules such as liver and kidney damage, lung nodules, and lymph nodes. Personalized 3D medical image models can be created for different objects from different locations, angles, and cross-sections. The creation of medical image models can be based on the size, shape, color, dimensions, and structure of the object, or it can be achieved by acquiring a large number of medical images and then analyzing these images using big data analytics. Models can also be created through a combination of the above methods. In this invention, the model can be a digital model or another type of model. It can be a vector model or a non-vector model; this invention is not limited thereto. 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 is used to store 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.

[0042] The areas to be irradiated for the patient include at least one of the following: body parts, organs, tissues, body regions, lesions, surgical sites, implanted devices, implanted equipment, implanted materials, suspicious locations, and key locations.

[0043] 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 individualized information of the patient, the specific area to be irradiated within the areas to be irradiated can be accurately analyzed, further narrowing the range of irradiation required, reducing the irradiation of areas that do not need to be examined, and reducing the radiation damage suffered by the patient.

[0044] The medical X-ray fluoroscopy device of the present invention includes an adjustable light source end protection device 14, which has an aperture through which X-rays pass and then irradiate the patient. The aperture through which X-rays pass is adjustable, and the area of ​​the patient's body irradiated by X-rays can be controlled by adjusting the position, size, and shape of the aperture. Figure 2a , Figure 2b This is a schematic diagram of an adjustable light source end protection device. Figure 2a As shown, 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 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 strips 143 can serve to block X-ray radiation.

[0045] like Figure 2b As shown, 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, the more strips that can be used, allowing for more precise adjustment of the shape of the portion that allows X-rays to pass through. Figure 2b For ease of drawing, only four masking bars are used on each side. In practice, dozens or even more masking bars can be used on each side as needed. Moving all masking bars 143 one unit to the left or right is equivalent to moving the X-ray channel one unit in that direction as well. If it's necessary to move the X-ray channel upwards (or downwards), the position of each row of masking bars can be adjusted to match the position of the row above (or below) it. Figure 2a , 2bIn the middle, 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.

[0046] 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 position, size and shape of the window through which the light outlet can be adjusted for X-rays to pass. This invention does not limit this.

[0047] 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. By adjusting the distance between the protective plate and the light source, the actual position, shape and size of the X-ray irradiation on the relevant part of the human body can be controlled. As long as it can achieve the goal of having a hole through which X-rays can pass and then 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.

[0048] The medical X-ray fluoroscopy device of this invention can be a medical X-ray machine, a CT scanner, or other medical devices that emit 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.

[0049] 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.

[0050] Specific methods could be:

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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 ranges required at different rotation positions.

[0057] 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.

[0058] See the second embodiment of the present invention. Figure 3 . Figure 3 This is a schematic diagram of the radiation protection device for a medical X-ray fluoroscopy device according to a second embodiment of the present invention. As shown in the figure, the radiation protection device for the medical X-ray fluoroscopy device of the present invention includes an information acquisition module 12, an analysis and calculation module 13, and an adjustable light source end protection device 14.

[0059] The information acquisition module 12 is used to acquire information about the areas of the patient that need to be irradiated and the patient's location.

[0060] The adjustable light source end protection device 14 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, 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.

[0061] 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 position, size and shape of the light outlet 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, size and shape of the light outlet according to the analysis and calculation results.

[0062] The radiation protection device for a medical X-ray fluoroscopy device of the present invention corresponds one-to-one with the medical X-ray fluoroscopy device of the present invention. For reference, please refer to the description of the aforementioned medical X-ray fluoroscopy device, which will not be repeated here.
