Abstract
Description
Technical field:
[0001] The utility model relates to the technical field of medical equipment, in particular to the field of X-ray imaging. Background technology:
[0002] At present, X-ray imaging technology is widely used in the medical field as a common medical diagnostic method to obtain X-ray images for doctors to use for diagnosis. Since X-rays have radiation and can cause certain damage to human health, an imaging device is usually installed at the ray outlet of the X-ray machine. Medical staff adjust the opening size of the light-emitting surface of the imaging device according to the distance between the X-ray source and the image receptor, namely SID or shooting distance (English full name: source to image receptor distance), to control the irradiation range of the X-rays and limit them to only the parts of the human body that need to be irradiated. In the prior art, medical staff generally measure the SID value by using a pull-out tape measure, and adjust the imaging device according to the measured SID value. This method of measuring the SID value is not only cumbersome to operate and affect work efficiency, but also prone to large errors, affecting the adjustment accuracy of the imaging device.
[0003] In the actual shooting process, different tissue parts of the body of the photographer may be blocked, such as the ulna and radius of the arm. If the shooting angle is wrong, it will cause image overlap and affect the doctor's judgment. Therefore, it is sometimes necessary to adjust the imaging device to a certain angle to shoot the desired shooting part. In the prior art, a tilt angle measuring device is usually installed on the imaging device to measure the tilt angle of the imaging device. This method is not only costly, the equipment is bloated, and the tilt angle measurement of the imaging device is troublesome, but also increases the overall weight of the imaging device, affecting the doctor's use.
[0004] When the photographer uses X-rays to take pictures, he or she is also exposed to radiation damage caused by X-rays to the body. Therefore, it is of utmost importance to obtain an X-ray image that meets the diagnostic requirements in just one shot. Currently, the photographer's shooting position is generally adjusted by medical staff based on visual inspection of visible light, and this method has unstable factors. In the case of an inappropriate shooting position, the captured image has defects such as incomplete shooting parts and poor clarity, which cannot meet the diagnostic requirements and may even need to be re-shot. This not only affects work efficiency, but in severe cases, the photographer needs to increase the number of shots and be exposed to more X-ray radiation, which is prone to safety hazards, and still cannot solve the problem of poor quality of X-ray images due to inappropriate shooting positions. Utility model content:
[0005] In order to solve the problems that the SID value measurement is cumbersome and prone to large errors, the imaging device is bulky, the inclination angle measurement is troublesome, the photographer's shooting position is inappropriate, the captured image has incomplete shooting parts and poor clarity, etc., the utility model proposes an X-ray imaging device.
[0006] The utility model provides an X-ray imaging device, comprising an adjustment component, a beam limiting component, an illumination component and an auxiliary component, characterized in that: the auxiliary component comprises an optical camera, an electronic distance measuring module, an electronic inclination measuring module, a control circuit board and a control circuit, the optical camera, the electronic distance measuring module, the electronic inclination measuring module and the control circuit are mounted on the control circuit board, the optical camera is connected to the photoelectric input end of the control circuit, the electronic distance measuring module is connected to the distance measuring input end of the control circuit, the electronic inclination measuring module is connected to the inclination measuring input end of the control circuit, the control circuit board is arranged on the beam limiting component near the light outlet side to ensure that the optical camera and the electronic distance measuring module are not blocked and work in coordination, thereby obtaining a clear optical image and an accurate distance value, which is conducive to doctors taking X-ray images that meet diagnostic conditions.
[0007] As a further improvement of the utility model, the beam limiting assembly includes: an A support plate, a B support plate, an A baffle group, and a B baffle group. The A baffle group is arranged on one side of the A support plate, and the B baffle group is arranged on one side of the B support plate. The A baffle group and the B baffle group are arranged relative to each other to construct a central light opening of the imaging device, thereby ensuring that the edges of the captured X-ray images are clear.
[0008] As a further improvement of the utility model, an outer casing is further provided, and the adjustment component includes: a left adjustment knob and a right adjustment knob, both of which are arranged on the outside of the outer casing and are used to adjust the A baffle group and the B baffle group respectively.
[0009] As a further improvement of the utility model, an inner casing is also provided, and the lighting assembly includes: a reflective lens, a light emitting device, and a shooting light source button. The light emitting device is arranged on the inner side of the inner casing, and the shooting light source button is arranged on the outer side of the outer casing. By adding the settings of inner and outer casings, the installation of different components is facilitated, and the lateral scattering of X-rays is effectively blocked, thereby reducing safety risks.
[0010] As a further improvement of the present invention, the reflective lens is arranged at the central light-transmitting opening of the A support plate and is placed at an angle.
[0011] As a further improvement of the utility model, the visible light emitted by the light emitting device is basically consistent with the X-ray projection area after being reflected by the reflective lens.
[0012] As a further improvement of the present invention, a display screen is also provided on the outside of the outer casing to display the distance value measured by the electronic distance measuring module and the angle value measured by the electronic inclination angle measuring module, which provides convenience for the doctor's operation.

[0014] As a further improvement of the utility model, a face mask is also provided, and the face mask is made of a transparent and light-transmitting material.
[0015] The beneficial effects of the utility model are as follows: by setting up the electronic distance measurement module, the manual distance measurement operation is bypassed, the distance error caused by human factors is avoided, and the accurate measurement of the shooting distance is realized, the efficiency is improved while avoiding the problem of the adjustment accuracy of the imaging device affected by the error. By setting up the electronic inclination angle measurement module, there is no need to install an additional independent inclinometer, which reduces the weight of the imaging device and reduces the cost, and can also measure the accurate inclination angle value, making it convenient to shoot multiple shooting parts as needed. By setting up the optical camera, the filming effect is evaluated by pre-shooting before the actual shooting, avoiding the defects of incomplete shooting parts and poor clarity of the X-ray image, and improving the accuracy, safety and work efficiency of X-ray shooting.

[0030] refer to Figures 1 to 4 As shown, the utility model provides an X-ray imaging device, including a connecting flange 1, a reflective lens 5, an A support plate 10, an A baffle group 15, a B support plate 20, a B baffle group 25, a control circuit board 30, a control circuit 32, an optical camera 35, an electronic ranging module 38, a light emitting device 40, an inner housing 42, an outer housing 45, a left adjustment knob 47, a right adjustment knob 49, a shooting light source button 52, a display screen 55, a mask 58 and an electronic inclination measurement module 60.
[0031] like Figure 1 , Figure 3 and Figure 4 As shown, the control circuit board 30 is arranged on the B support plate 20 near the light outlet side, and the control circuit 32, the optical camera 35, the electronic ranging module 38 and the electronic inclination angle measurement module 60 are installed on the control circuit board 30, the optical camera 35 is connected to the photoelectric input end of the control circuit 32, the electronic ranging module 38 is connected to the ranging input end of the control circuit 32, and the electronic inclination angle measurement module 60 is connected to the inclination angle measurement input end of the control circuit 32.
[0032] like Figure 1 , Figure 2 , Figure 3As shown, the A baffle group 15 is provided on one side of the A support plate 10, the B baffle group 25 is provided on one side of the B support plate 20, and the control circuit board 30 is provided on the other side of the B support plate 20, and the A baffle group 15 is arranged opposite to the B baffle group 25. The A support plate 10 and the B support plate 20 are both provided with light transmission ports in the middle to allow X-rays to pass through, and the reflective lens 5 is arranged at the central light transmission port of the A support plate 10 and is tilted at an angle of about 45°. The tilted arrangement of the reflective lens 5 facilitates the visible light to have a light field that is substantially consistent with the X-ray irradiation field after being reflected.
[0033] like Figure 1 As shown, there are two layers of casing, inner and outer. By adding a layer of casing, the radiation of X-rays to the surrounding can be effectively shielded, the risk of direct exposure of X-rays to the surrounding personnel can be reduced, and the possibility of radiation exposure can be reduced. The outer side of the outer casing 45 is provided with the left adjustment knob 47, the right adjustment knob 49, the shooting light source button 52 and the display screen 55, and the inner side of the inner casing 42 is provided with the light-emitting device 40. The mask 58 is made of transparent and light-transmitting material so that X-rays and visible light can pass through without being affected. The optical camera 35 and the electronic distance measurement module 38 can obtain clear optical images and accurate distance values through the transparent mask 58. For the same purpose, the bottom of the inner casing 42 and the outer casing 45 after assembly is mostly hollowed out to ensure that the optical camera 46 and the electronic distance measurement module 42 are not blocked, so as to facilitate obtaining clear optical images and accurate distance values. The electronic inclination angle measurement module 60 sets the X-ray beam limiter assembly to a horizontal zero inclination angle under normal working conditions. When the angle needs to be adjusted, the angle measured by the electronic inclination angle measurement module 60 is the inclination angle with the horizontal plane measured by the sensor when the imaging device is working horizontally rather than vertically. When the imaging device rotates clockwise, the measured angle is a positive inclination angle value, and when it rotates counterclockwise, the measured angle is a negative inclination angle value.
[0034] In actual filming, when the doctor positions the mobile imaging device for the photographer, the electronic distance measurement module 38 and the electronic tilt angle measurement module 60 are turned on, and the measured SID value and tilt angle value are transmitted to the control circuit 32, such as Figure 6 As shown, the control circuit 32 displays the SID value and the inclination angle value on the display screen 55, so that the doctor can clearly see the shooting distance value and the inclination angle value and make adjustments. At this time, the doctor presses the shooting light source button 52, as shown in FIG. Figure 5As shown, the light emitting device 40 is turned on, and the emitted visible light has a light field that is basically consistent with the X-ray irradiation field after being reflected by the reflective lens 5, so that the doctor can determine the X-ray irradiation field before shooting. The doctor positions or adjusts the photographer according to the visible light field, and uses the left adjustment knob 47 and the right adjustment knob 49 to adjust the positions of the A baffle group 15 and the B baffle group 25 respectively, to block the areas that do not need to be irradiated, so that the visible light field only irradiates the parts that need to be irradiated. After the irradiation area is adjusted, the shooting light source button 52 is pressed again, the optical camera 35 shoots the image and transmits it to the control circuit 32, and then the light emitting device 40 is turned off. The control circuit 32 sends the captured optical image to the desktop of the console through the connection with the console port, so that the doctor can evaluate the filming effect before the actual filming. Through this pre-shooting method, the doctor can further evaluate the effect of the upcoming X-ray filming, whether the filming part is completely captured, whether the photographer's shooting position needs to be adjusted, and other information. After the evaluation is correct, the filming is started to obtain an X-ray image that meets the diagnostic requirements.
[0035] In summary, the X-ray imaging device proposed by the utility model, through the settings of the optical camera, the electronic distance measurement module and the electronic inclination measurement module, allows the doctor to clearly and conveniently know the shooting distance value and the inclination angle value through the display screen when the imaging device is moved. Through the pre-shooting method of the optical camera, the doctor can further evaluate the actual filming effect, and the photographer can make timely adjustments if the shooting position is not appropriate. An X-ray image that meets the diagnosis requirements can be obtained with a one-time shooting, avoiding the defects of incomplete shooting parts and poor clarity in the X-ray image, thereby improving the accuracy, safety and work efficiency of X-ray shooting.

For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the present invention.
