Description

TECHNICAL FIELD

[0001] The present application relates to the field of high-efficiency X-ray imaging detection, and in particular to a high-efficiency X-ray imaging detection and recognition device. BACKGROUND

[0002] Traditional hot cathode X-ray tubes have some limitations, such as long start-up time, high energy consumption, and large size. This has prompted research and development of new X-ray sources. The continuous progress of cold cathode technology in the field of electronics has made it possible to innovate X-ray tubes. Research on cold cathode materials and structures has improved electron emission efficiency and extended the life of the device. In the fields of medical diagnosis, industrial non-destructive testing, and security inspection, the performance requirements for X-ray detection equipment are constantly increasing, such as higher resolution, faster imaging speed, and lower radiation dose. The development of image processing and computer technology has enabled more complex and accurate processing and analysis of images obtained from X-ray detection, thereby improving the accuracy and reliability of detection. The emergence of new detector materials and shielding materials has helped to improve the performance and safety of detection equipment. With increasing awareness of energy and the environment, there are increasingly stringent requirements for the energy consumption and radiation protection of X-ray detection equipment, which has driven the development of high-efficiency, low-radiation technology.

[0003] Chinese Patent Publication No. CN103260327B discloses a tube current stabilizing device for a grid-controlled cold cathode X-ray bulb. The structure of the device is composed of an isolation rectifier, a high-frequency inverter, a closed-loop control, a reference unit, a grid-controlled bulb, a current sampling unit, a grid voltage sampling unit, and an addition unit. The device automatically collects the changes in the grid voltage and tube current during exposure using a grid voltage detection unit and a tube current sampling unit. The mode selection unit judges the sampled grid voltage and tube current and selects the corresponding working mode to control the tube current and exposure time. The advantages of the device are that it controls the output power of the grid voltage to meet the normal operating requirements of the machine and the high-voltage requirements, and it controls the time to meet the dose requirements of the X-ray. It can be seen that the tube current stabilizing device for the grid-controlled cold cathode X-ray bulb cannot achieve automatic segmentation of important organs and automatic recognition of trauma conditions through intelligent segmentation and detection recognition algorithms.

[0045] Adjusting the opposite moving speed of the moving unit, or, determining the distance between the X-ray tube and the detector array 1 according to the display density of the feature points of the image, adjusting the adjustment speed of the distance between the X-ray emitting unit X-ray tube and the detector array 1 according to the interval length between the emitting time of the X-ray and the receiving time of the X-ray by the detector array 1.

[0046] Specifically, the display unit 8 can be a display screen or an image display in practice.

[0047] In the implementation, the application determines the working voltage by detecting the internal air temperature of the X-ray tube through the temperature sensor, which helps to prolong the service life of the X-ray tube and improve the stability and accuracy of the X-ray emission; the working voltage of the X-ray tube is reduced, which overcomes the problem of internal temperature rise caused by impact; the opposite moving speed of the X-ray tube relative to the object to be detected is increased to reduce the influence of airflow extrusion on the absorption or reflection of the X-ray, which overcomes the problem of X-ray loss caused by window wear, realizes fast detection and improves detection efficiency.

[0048] Specifically, the X-ray emitting unit further comprises:

[0049] A high-voltage driver connected to the X-ray tube for providing an excitation voltage for the X-ray tube to generate X-rays;

[0050] A power supply connected to the high-voltage driver for providing power to the high-voltage driver.

[0051] A fixed rod 9 connected to the X-ray tube 2 for fixing the position and posture of the X-ray tube 2.

[0052] Specifically, the X-ray emitting unit further comprises:

[0053] Specifically, the moving unit comprises:

[0054] A first moving assembly 10 connected to the high-voltage driver 5 for adjusting the opposite moving speed of the X-ray tube relative to the object to be detected, comprising a first electric telescopic rod connected to the high-voltage driver 5;

[0055] A second moving assembly 4 connected to the X-ray tube 2 for adjusting the distance between the X-ray emitting unit X-ray tube and the detector array 1, comprising a motor-driven lead screw connected to the X-ray tube 2.

[0056] In the implementation, the application overcomes the problem that different detection objects have different requirements for the detection accuracy and resolution by setting the first moving assembly 10 and the second moving assembly 4, adjusting the opposite moving speed of the X-ray tube relative to the object to be detected and the distance between the X-ray tube and the detector array 1, respectively controlling the movement of the high-voltage driver 5 and the X-ray tube, and setting independent moving assemblies, thereby increasing the versatility and applicability of the equipment and improving the performance and reliability of the entire detection equipment.

[0057] Specifically, the control unit determines the damage degree of the equipment structure according to the internal air temperature of the X-ray tube 2, and if the internal air temperature of the X-ray tube 2 is greater than the preset temperature, it is determined that the damage degree of the equipment structure does not meet the requirements, and the working voltage of the X-ray tube 2 is reduced.

[0058] Optionally, the preset temperature can be in the range of [70℃, 80℃];

[0059] Preferably, the preferred embodiment of the preset temperature is 75℃;

[0060] In one embodiment, the internal air temperature of the X-ray tube 2 is 85℃, it is determined that the damage degree of the equipment structure does not meet the requirements, and for every 2℃ that the internal air temperature of the X-ray tube 2 exceeds the preset temperature, the working voltage of the X-ray tube 2 is reduced by 3KV from the current working voltage of the X-ray tube 2. The current working voltage of the X-ray tube 2 is 90KV, and the reduced working voltage of the X-ray tube 2 is 75KV.

[0061] In the implementation, the application overcomes the problem that due to the impact on the structure during previous use, part of the structure is deformed, causing the internal resistance to rise, and the temperature rise rate is higher than when there is no impact. The damage degree of the equipment structure is determined according to the internal air temperature of the X-ray tube, and the working voltage is reduced when the temperature is too high, which can effectively prevent the equipment from being severely damaged due to overheating, prolong the service life of the equipment, reduce the potential safety hazards caused by excessive damage to the equipment, avoid the abnormal X-ray emission caused by the damage to the equipment structure, and thus ensure the accuracy and reliability of the X-ray detection. By reducing the working voltage when the temperature is too high, potential equipment failures can be prevented, maintenance costs can be reduced, and the stability of the equipment performance can be maintained, so that the equipment can maintain a good working state in long-term operation.

[0062] Specifically, the control unit determines the stability of the detection according to the variance of the interval length between the X-ray emission time and the imaging display time, and if the variance of the interval length is greater than a preset second variance, it is determined that the stability of the detection does not meet the requirements, and the opposite moving speed is increased.

[0063] Optionally, the preset second variance can be in a range of (3s, 6s];

[0064] Preferably, a preferred embodiment of the preset second variance is 4s;

[0065] In a specific embodiment, the variance of the interval duration is 7s, which is greater than the preset second variance, and it is determined that the stability of the detection does not meet the requirements. The interval duration is greater than the preset second variance by 1s, and the opposite moving speed is increased to 1.1 times of the current opposite moving speed. The current opposite moving speed is 13 cm / s, and the increased opposite moving speed is 13 x 1.1 7-4 = 17.3 cm / s.

[0066] Specifically, if the variance of the interval duration between the X-ray emission time and the imaging display time is greater than the preset first variance and less than or equal to the preset second variance, it is determined that the stability of the detection does not meet the requirements due to the effectiveness of the ray transmission not meeting the requirements, and the effectiveness of the ray transmission is re-determined according to the display density of the feature points of the image. If the display density of the feature points of the image is greater than the preset second display density, it is re-determined that the effectiveness of the ray transmission does not meet the requirements, and the distance between the X-ray tube and the detector array 1 is shortened.

[0067] The display density of the image feature points is the ratio of the number of image feature points in the X-ray image region to the area of the X-ray image region.

[0068] Optionally, the preset first variance can be in a range of [1s, 3s], and the preset second display density can be in a range of [8 / mm 2 , 10 / mm 2 ];

[0069] Preferably, a preferred embodiment of the preset first variance is 2s, and a preferred embodiment of the preset second display density is 9 / mm 2 ;

[0070] In a specific embodiment, the variance of the interval duration is 2.5s, the display density of the feature points of the image is 12 / mm 2 , the variance of the interval duration is greater than the preset first variance and less than the preset second variance, and it is determined that the stability of the detection does not meet the requirements due to the effectiveness of the ray transmission not meeting the requirements.

[0071] The display density of the feature points of the image is greater than the preset second display density by 1 / mm 2, the distance between the X-ray tube and the detector array 1 is shortened by 5 cm, the current distance between the X-ray tube and the detector array 1 is 100 cm, and the distance between the X-ray tube and the detector array 1 after shortening is 100-5x(12-9)=85 cm.

[0072] In the implementation, the preset first variance and the preset second variance are set, the case of ray loss due to the use of the window part for a long time and the resulting wear is overcome, that is, part of the gas inside the X-ray tube 2 is caused to absorb or reflect and refract the rays, thereby causing the case of ray loss; the stability of the variance determination detection is determined, and the opposite moving speed is increased when the requirement is not met, which helps to reduce the time fluctuation in the detection process and improve the consistency and reliability of the detection result; the opposite moving speed is adjusted to improve the unstable case and reduce the risk of misdiagnosis.

[0073] Specifically, if the interval length between the emission time of the X-ray and the receiving time of the X-ray by the detector array 1 is greater than the preset interval length, the adjustment speed of the distance between the X-ray tube and the detector array 1 is increased during adjustment.

[0074] The adjustment speed of the distance between the X-ray tube and the detector array 1 is the ratio of the difference between the distance between the X-ray tube and the detector array 1 before adjustment and the distance between the X-ray tube and the detector array 1 after adjustment to the time required to complete the distance adjustment.

[0075] In the implementation, the preset interval length is set, and the adjustment speed of the distance between the X-ray tube and the detector array 1 of the X-ray emission unit is adjusted according to the interval length between the emission time of the X-ray and the receiving time of the X-ray by the detector array 1, which overcomes the problem that the interval length through different objects to be detected is different due to the different characteristics of X-ray absorption and scattering caused by the different densities of the objects to be detected, reduces the signal blur or distortion caused by improper distance, and improves the clarity and resolution of imaging.

[0076] Optionally, the preset interval length can be [2s, 4s];

[0077] Preferably, the preferred embodiment of the preset interval length is 3s;

[0078] In one or more specific embodiments, the interval length between the emission time of the X-ray and the receiving time of the X-ray by the detector array is 3.5s, which is greater than the preset interval length, and the stability of the ray transmission is determined to be not meet the requirements;

[0079] The interval length between the emission time of the X-rays and the receiving time of the X-rays by the detector array is greater than a preset interval length by 1s, and the adjustment speed of the distance between the X-ray tube and the detector array 1 is increased to 1.2 times of the current adjustment speed of the distance between the X-ray tube and the detector array 1, and the current adjustment speed of the distance between the X-ray tube and the detector array 1 is 1.9 cm / s, and the increased adjustment speed of the distance between the X-ray tube and the detector array 1 is 1.9*1.2 8-6 =2.736 cm / s.

[0080] The distance between the X-ray tube and the detector array 1 is adjusted by a motor-driven screw.

[0081] In the implementation, the present application overcomes the problem that the transmission of the rays in the air is disturbed when part of the material volatilizes into the air due to the aging of the imaging structure in the process of ray transmission by setting the first display density and the second display density. The preliminary judgment is made by the variance of the interval length, and the secondary judgment is made by the display density of the image feature points, so that the cause of the detection stability not meeting the requirements can be found more accurately. The distance between the X-ray tube and the detector array 1 is adjusted according to the judgment result, the divergence angle of the X-rays and the receiving angle of the detector are changed by adjusting the distance between the X-ray tube and the detector array 1, so as to affect the resolution of the imaging, which helps to optimize the transmission of the rays and improve the accuracy and reliability of the detection. Different adjustment measures are taken for different degrees of feature point display density to improve the detection efficiency.

[0082] Specifically, the interval length between the X-ray emission time and the imaging display time is the interval length from the time when the X-rays are emitted from the X-ray emission source to the time when the image is presented on the display device; and the display density of the feature points of the image is the ratio of the number of feature points to the area of the image.

[0083] The calculation process of the variance of the interval length is a conventional technical means known to those skilled in the art, and thus the calculation process of the variance of the interval length will not be described here.

[0084] Specifically, the interval length between the emission time of the X-rays and the receiving time of the X-rays by the detector array 1 is the time interval from the moment when the X-ray emission source starts to emit X-rays to the time when the detector array 1 receives the X-rays.

[0085] The technical scheme of the present application has been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical schemes after the changes or replacements will all fall within the protection scope of the present application.
