Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to an intelligent imaging system. Background Art

[0002] With the continuous development of modern medical technology, CT scanning is an important means of detecting injuries and diseases in modern medical treatment. Medical imaging plays an important role in disease diagnosis and treatment. People have higher and higher requirements for its imaging effect. Traditional X-ray medical imaging technology will produce certain radiation during X-ray irradiation medical imaging, which has an impact on human health. It is extremely important to control the radiation dose.

[0003] A patent document with Chinese patent publication number CN103957799A discloses an X-ray imaging system, comprising: an X-ray tube, a ceiling suspension for the X-ray tube, a detector cart on which an X-ray detector is mounted, an active sensor matrix, an optical indication unit, and a control unit, wherein the active sensor matrix is ​​fixedly mounted on the ceiling suspension, wherein the optical indication unit is fixedly mounted to the detector cart and is suitable for emitting optical indications onto the active sensor matrix, wherein the control unit is connected to the active sensor matrix and is suitable for collecting the position of the optical indication on the active sensor matrix and creating a control signal to control at least one of the ceiling suspension and the detector cart to adjust the position of the optical indication to a predetermined position.

[0004] It can be seen that in the prior art, when performing X-ray medical imaging, the same X-ray exposure is performed on different people to obtain medical images of the same quality, and it is impossible to obtain the required medical image with the smallest possible X-ray intensity according to the human body condition. Summary of the invention

[0005] To this end, the present invention provides an intelligent imaging system for performing the same X-ray irradiation on different people to obtain medical images of the same quality when performing X-ray medical imaging in the prior art, and it is impossible to obtain the required medical image with the smallest possible X-ray intensity according to the human body condition.

[0006] To achieve the above object, the present invention provides an intelligent imaging system, comprising:

[0007] An X-ray tube comprising a housing, a carbon nanotube array and a palladium material,

[0008] The shell is used to wrap the carbon nanotube array and the palladium material, the carbon nanotube array is used to generate different currents to impact the palladium material, and the palladium material is used to generate X-rays with different intensities;

[0009] An intensity attenuation detection module, which is connected to the X-ray tube and is used to collect the intensity of the X-ray entering the human body and the intensity of the X-ray exiting the human body to obtain a real-time X-ray intensity attenuation value of the injured or diseased part of the human body;

[0010] An image acquisition module, connected to the X-ray tube, for acquiring medical images generated after the X-rays irradiate the injured or diseased part of the human body;

[0011] An adjustment control module is connected to the X-ray tube, the intensity attenuation detection module and the image acquisition module, and is used to compare the real-time X-ray intensity attenuation value with the standard X-ray intensity attenuation range, and determine whether it is necessary to adjust the initial current size based on the comparison result to obtain a temporary current size, and determine whether it is necessary to adjust the temporary current size to obtain a target current size based on the image quality of the medical image generated by the X-ray of the temporary current size.

[0012] Furthermore, the adjustment control module includes a determination module for determining the real-time X-ray intensity attenuation value according to the standard X-ray intensity attenuation range.

[0013] If the real-time X-ray intensity attenuation value is less than the standard X-ray intensity attenuation range, reducing and adjusting the initial current magnitude to obtain the temporary current magnitude;

[0014] If the real-time X-ray intensity attenuation value is equal to the standard X-ray intensity attenuation range, no adjustment is performed, and the initial current magnitude is the temporary current magnitude;

[0015] If the real-time X-ray intensity attenuation value is greater than the standard X-ray intensity attenuation range, the initial current magnitude is increased and adjusted to obtain the temporary current magnitude.

[0016] Furthermore, the image acquisition module is also used to acquire images of a human body lying flat, and analyze the medical images to obtain two image quality parameters: image resolution and image grayscale.

[0017] Furthermore, the image acquisition module is provided with X-ray standard images of different parts of the human body, and the medical image is compared with the X-ray standard image in terms of image resolution and image grayscale to obtain a real-time image quality score. The adjustment control module also includes an adjustment module, which is connected to the determination module and is used to compare the real-time image quality score with a preset target image quality score, and determine whether it is necessary to adjust the temporary current size to obtain the target current size based on the comparison result, wherein:

[0018] When the real-time image quality score is less than the preset target image quality score, it is determined that the temporary current magnitude needs to be adjusted to obtain the target current magnitude;

[0019] When the real-time image quality score is greater than or equal to the preset target image quality score, it is determined that there is no need to adjust the temporary current size, and the temporary current size is the target current size.

[0020] Furthermore, the adjustment control module is provided with a first adjustment number and a second adjustment number when adjusting the initial current size. The first adjustment number is selected when decreasing the initial current size, and the second adjustment number is selected when increasing the initial current size, wherein the first adjustment number is twice the second adjustment number.

[0021] Furthermore, the intensity attenuation detection module collects the initial current magnitude, collects the residual current magnitude corresponding to the X-rays emitted after being absorbed by the human body after the X-rays pass through the human body, and determines the real-time X-ray intensity attenuation value according to the initial current magnitude and the residual current magnitude;

[0022] Among them, As=1-I / I0, where As is the real-time X-ray intensity attenuation value, I is the residual current size, and I0 is the initial current size.

[0023] Further, the image quality score = W1*resolution score + W2*image grayscale score, wherein W1 is the resolution weight coefficient, W2 is the image grayscale weight coefficient, and W1+W2=1;

[0024] Resolution score = medical image resolution / standard image resolution * 100;

[0025] Image grayscale score = medical image grayscale / standard image grayscale*100.

[0026] Furthermore, the adjustment control module further includes an analysis unit and a determination unit, wherein the analysis unit is used to analyze the longitudinal height of the X-ray irradiation area of ​​the human body at a lying angle when the X-ray irradiates the injured or diseased part of the human body;

[0027] The determination unit is connected to the analysis unit and the judgment unit, and is used to determine the X-ray penetration distance of the human body according to the longitudinal height, and determine the standard X-ray intensity attenuation range based on the X-ray penetration distance of the human body.

[0028] Furthermore, the initial current magnitude is related to the distance that the X-ray penetrates the human body, and the adjustment control module determines the initial current magnitude according to the distance that the X-ray penetrates the human body.

[0029] Furthermore, the adjustment control module also includes a control module for independently controlling the carbon nanotube array in different zones, wherein the carbon nanotube array is divided into a plurality of independently controlled zones, and each zone independently adjusts the number of carbon nanotubes excited to adjust the initial current.

[0030] Compared with the prior art, the beneficial effect of the present invention lies in that the X-ray intensity attenuation value is monitored by the intensity attenuation module, and the initial current of the carbon nanotube array is adjusted according to the attenuation value, thereby obtaining high-quality medical images while reducing the radiation damage of X-rays to the human body, which helps to improve the quality of medical images and the accuracy of medical diagnosis. The adjustment control module adjusts the carbon nanotube array in real time according to the quality of the medical image, ensuring that the quality of the medical image meets the requirements while avoiding excessive radiation of X-rays, thereby improving the efficiency and safety of medical diagnosis.

[0031] Furthermore, by collecting images of the human body at a lying angle, the distance that the X-ray irradiation area penetrates the human body can be accurately obtained, providing important parameters for calculation. By identifying the number of pixels in the medical image, accurate image resolution information can be obtained, which is helpful for evaluating the image quality. By analyzing the various types of gray shades between pure black and pure white in the image, the image grayscale level can be determined, which helps to judge the image contrast and detail performance.

[0032] Furthermore, by real-time monitoring of X-ray intensity attenuation and comparing it with the preset standard X-ray intensity attenuation range, the initial current can be intelligently adjusted to achieve precise control of X-ray intensity. The automatic and intelligent features greatly reduce the workload of medical staff.

[0033] Furthermore, by objectively and accurately evaluating the quality of the collected medical images, the specific image quality score is compared with the preset target score, and it is automatically determined whether the temporary current size needs to be adjusted. This intelligent decision-making mechanism greatly improves the efficiency and accuracy of image acquisition. The electron beam current is adjusted according to the initial adjustment number. If the quality score still does not reach the preset target score, the adjustment range is automatically halved and optimization continues. This progressive adjustment strategy can not only effectively improve image quality, but also minimize unnecessary radiation to the human body.

[0034] Furthermore, through two different adjustment parameters, the first adjustment number and the second adjustment number, accurate and efficient control of the electron beam current can be achieved. By setting the first adjustment number to twice the second adjustment number, this asymmetric adjustment strategy can achieve a faster response when reducing the current, effectively preventing excessive radiation, while maintaining a relatively smooth adjustment range when increasing the current, thereby ensuring the stability of the image quality.

[0035] Furthermore, by comparing the X-rays entering the human body with those emitted from the human body, the degree of X-ray absorption by the human body is intuitively reflected. This real-time, quantitative X-ray attenuation detection method helps to minimize the radiation exposure of patients while ensuring image quality, thereby improving the safety and diagnostic effectiveness of X-ray examinations.

[0036] Furthermore, by adding weights to image resolution and grayscale values ​​respectively, the two key factors of resolution and image grayscale can be considered simultaneously, and a comprehensive score is given based on their relative importance, which fully reflects the overall quality of the image and can be flexibly adjusted according to different clinical needs, helping to better optimize medical images.

[0037] Furthermore, the X-ray intensity is automatically adjusted according to the body characteristics of each patient, avoiding the problem of excessive radiation or insufficient dose, and achieving more accurate personalized dose control. By analyzing the longitudinal height of the X-ray irradiation area at the human body's lying angle, the system can more accurately determine the actual penetration distance of X-rays in the human body, further improving the accuracy of X-ray intensity regulation.

[0038] Furthermore, by determining the initial current size based on the distance that X-rays penetrate the human body, a more accurate initial dose can be provided for each patient. This method ensures that the X-ray intensity can be matched to the patient's body size from the beginning, greatly reducing the risk of over- or under-exposure, and achieving a higher degree of standardization between different examinations, thereby improving the comparability and consistency of examination results.

[0039] Furthermore, by dividing the carbon nanotube array into independent grid areas, more refined control of X-ray emission can be achieved. This regional control method can adjust the X-ray intensity according to different body parts, ensuring that each part receives an appropriate amount of X-rays. This not only improves image quality, but also reduces unnecessary radiation received by the human body and enhances human safety. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 3 is a system framework diagram of an intelligent imaging system according to an embodiment of the present invention, Figure 4 The structure diagram of the adjustment control module of the embodiment of the present invention is as follows. The embodiment of the present invention provides an intelligent imaging system, including an X-ray tube 1, an intensity attenuation detection module 2, an image acquisition module 3 and an adjustment control module 4, wherein the X-ray tube 1 includes a housing 11, a carbon nanotube array 12 and a palladium material 13,

[0049] The shell 11 is used to wrap the carbon nanotube array 12 and the palladium material 13, the carbon nanotube array 12 is used to generate different currents to impact the palladium material 13, and the palladium material 13 is used to generate X-rays with different intensities;

[0050] An intensity attenuation detection module 2, which is connected to the X-ray tube 1, and is used to collect the intensity of the X-ray entering the human body and the intensity of the X-ray exiting the human body to obtain a real-time X-ray intensity attenuation value of the injured or diseased part of the human body;

[0051] An image acquisition module 3, which is connected to the X-ray tube 1 and is used to obtain medical images generated after the X-rays irradiate the injured or diseased part of the human body;

[0052] The adjustment control module 4 is connected to the X-ray tube 1, the intensity attenuation detection module 2 and the image acquisition module 3, and is used to compare the real-time X-ray intensity attenuation value with the standard X-ray intensity attenuation range, and determine whether it is necessary to adjust the initial current size based on the comparison result to obtain a temporary current size, and determine whether it is necessary to adjust the temporary current size based on the image quality of the medical image generated by the X-ray of the temporary current size to obtain a target current size.

[0053] Specifically, the carbon nanotube array emits electrons to generate X-rays to irradiate injured or diseased parts of the human body to produce medical images. The carbon nanotube array 12 is adjusted according to the real-time X-ray intensity attenuation and the quality of the medical image to determine the X-rays with good medical image effect and low intensity.

[0054] Specifically, the intensity attenuation value of the X-ray intensity is monitored by the intensity attenuation module, and the initial current of the carbon nanotube array 12 is adjusted according to the attenuation value, so as to obtain high-quality medical images while reducing the radiation damage of X-rays to the human body, which helps to improve the quality of medical images and improve the accuracy of medical diagnosis. The adjustment control module 4 adjusts the carbon nanotube array 12 in real time according to the quality of the medical images, ensuring that the quality of the medical images meets the requirements while avoiding excessive radiation of X-rays, thereby improving the efficiency and safety of medical diagnosis.

[0055] Specifically, the image acquisition module 3 is also used to acquire images of a human body lying flat, and analyze the medical images to obtain two image quality parameters: image resolution and image grayscale.

[0056] Specifically, the image acquisition module 3 acquires images of a human body lying flat, obtains the penetration distance of the X-ray irradiation area into the human body based on the images of the human body lying flat, obtains the image resolution by identifying the number of pixels in the medical image, and obtains the image grayscale based on various gray shades between pure black and pure white in the image.

[0057] Specifically, by collecting images of the human body at a lying angle, the distance that the X-ray irradiation area penetrates the human body can be accurately obtained, providing important parameters for calculation. By identifying the number of pixels in the medical image, accurate image resolution information can be obtained, which helps to evaluate the image quality. By analyzing the various types of gray shades between pure black and pure white in the image, the image grayscale level can be determined, which helps to judge the image contrast and detail performance.

[0058] Specifically, the adjustment control module 4 includes a determination module for determining the real-time X-ray intensity attenuation value according to the standard X-ray intensity attenuation range.

[0059] If the real-time X-ray intensity attenuation value is less than the standard X-ray intensity attenuation range, reducing and adjusting the initial current magnitude to obtain the temporary current magnitude;

[0060] If the real-time X-ray intensity attenuation value is equal to the standard X-ray intensity attenuation range, no adjustment is performed, and the initial current magnitude is the temporary current magnitude;

[0061] If the real-time X-ray intensity attenuation value is greater than the standard X-ray intensity attenuation range, the initial current magnitude is increased and adjusted to obtain the temporary current magnitude.

[0062] In the specific implementation process, the standard X-ray intensity attenuation range is 85%<P≤90%,

[0063] When the real-time X-ray intensity attenuation P is P=84%, which is less than the standard X-ray intensity attenuation range of 85%<P≤90%, it is determined that the X-ray intensity is too high, and the initial current size is reduced and adjusted to obtain a temporary current size;

[0064] When the real-time X-ray intensity attenuation P is P=87%, the real-time X-ray intensity attenuation is within the standard X-ray intensity attenuation range of 85%<P≤90%, and it is determined as the preliminary X-ray intensity standard, and no adjustment is made, and the initial current size is the temporary current size;

[0065] When the real-time X-ray intensity attenuation P is P=95%, which is greater than the standard X-ray intensity attenuation range of 85%<P≤90%, it is determined that the X-ray intensity is too low, and the initial current size is increased and adjusted to obtain a temporary current size.

[0066] Specifically, by real-time monitoring of X-ray intensity attenuation and comparing it with the preset standard X-ray intensity attenuation range, the initial current can be intelligently adjusted to achieve precise control of X-ray intensity. The automatic and intelligent features greatly reduce the workload of medical staff.

[0067] Specifically, the image acquisition module 3 is provided with X-ray standard images of different parts of the human body, and the medical image is compared with the X-ray standard image in terms of image resolution and image grayscale to obtain a real-time image quality score. The adjustment control module 4 also includes an adjustment module, which is connected to the determination module to compare the real-time image quality score with the preset target image quality score, and determine whether it is necessary to adjust the temporary current size to obtain the target current size based on the comparison result, wherein:

[0068] When the real-time image quality score is less than the preset target image quality score, it is determined that the temporary current magnitude needs to be adjusted to obtain the target current magnitude;

[0069] When the real-time image quality score is greater than or equal to the preset target image quality score, it is determined that there is no need to adjust the temporary current size, and the temporary current size is the target current size.

[0070] Specifically, the preset target image quality score is 80 points. When the image quality score obtained by comparing the image resolution and image grayscale of the medical image with the X-ray standard image is less than 80 points, it is determined that the temporary current size needs to be adjusted to obtain the target current size. The temporary current size is increased or decreased according to the preset initial adjustment number A3, and the image quality score is obtained by analyzing the adjusted image. If it is less than the target image quality score, the initial adjustment number is reduced by half until the image quality score is not less than the preset target image quality score.

[0071] Specifically, by objectively and accurately evaluating the quality of the collected medical images, the specific image quality score is compared with the preset target score, and it is automatically determined whether the temporary current size needs to be adjusted. This intelligent decision-making mechanism greatly improves the efficiency and accuracy of image acquisition. The electron beam current is adjusted according to the initial adjustment number. If the quality score still does not reach the preset target score, the adjustment range is automatically halved and optimization continues. This progressive adjustment strategy can not only effectively improve image quality, but also minimize unnecessary radiation to the human body.

[0072] Specifically, the adjustment control module 4 is provided with a first adjustment number and a second adjustment number when adjusting the initial current size. The first adjustment number is selected when reducing the initial current size, and the second adjustment number is selected when increasing the initial current size, wherein the first adjustment number is twice the second adjustment number.

[0073] Specifically, when adjusting the initial current magnitude I0, the adjustment control module 4 gradually adjusts the initial current magnitude I0 according to the first adjustment number A1 and the second adjustment number A2, wherein the first adjustment number A1=I0 / 25, A2=I0 / 50.

[0074] In the specific implementation process, when the initial current size I0 = 200mA, the first adjustment number A1 = 8mA and the second adjustment number A2 = 4mA, at this time the real-time X-ray intensity attenuation value is 91%, and the initial current size needs to be increased and adjusted to obtain an adjusted X-ray intensity attenuation value of 87%, which meets the standard X-ray intensity attenuation range.

[0075] Specifically, through two different adjustment parameters, the first adjustment number and the second adjustment number, accurate and efficient control of the electron beam current can be achieved. The first adjustment number is set to twice the second adjustment number. This asymmetric adjustment strategy can achieve a faster response when reducing the current, effectively preventing excessive radiation. At the same time, it maintains a relatively smooth adjustment range when increasing the current, thereby ensuring the stability of image quality.

[0076] Specifically, the intelligent imaging system according to claim 1 is characterized in that the intensity attenuation detection module 2 collects the initial current magnitude, collects the residual current magnitude corresponding to the X-rays emitted after being absorbed by the human body after the X-rays pass through the human body, and determines the real-time X-ray intensity attenuation value according to the initial current magnitude and the residual current magnitude;

[0077] Among them, As=1-I / I0, where As is the real-time X-ray intensity attenuation value, I is the residual current size, and I0 is the initial current size.

[0078] In the specific implementation process, the control and regulation module controls the initial current size generated by the nanotube array to be I0=200mA, and the intensity attenuation detection module 2 collects the residual current size corresponding to the X-ray emitted after passing through the human body, which is I=24mA, and determines that the X-ray intensity attenuation value at this time is As=1-I / I0=88%.

[0079] Specifically, by comparing the X-rays entering the human body with those emitted from the human body, the degree of X-ray absorption by the human body is intuitively reflected. This real-time, quantitative X-ray attenuation detection method helps to minimize the radiation exposure of patients while ensuring image quality, thereby improving the safety and diagnostic effectiveness of X-ray examinations.

[0080] Specifically, the image quality score = W1*resolution score + W2*image grayscale score, where W1 is the resolution weight coefficient, W2 is the image grayscale weight coefficient, and W1+W2=1;

[0081] Resolution score = medical image resolution / standard image resolution * 100;

[0082] Image grayscale score = medical image grayscale / standard image grayscale*100.

[0083] During the specific implementation process, the preset resolution weight coefficient W1 = 60% and the image grayscale weight coefficient W2 = 40%, the standard image resolution is 1920x1080, the standard image grayscale is 400, the obtained medical image resolution is 1280x1080, and the medical image grayscale is 320. The resolution score = 1920x1080 / (1640x1080)*100≈85, the image grayscale score = 320 / 400*100=80, and the image quality score = 0.6*85+0.4*80=83.

[0084] Specifically, by adding weights to image resolution and grayscale values ​​respectively, it is possible to consider two key factors, resolution and image grayscale, at the same time, and make a comprehensive score based on their relative importance, which fully reflects the overall quality of the image and can be flexibly adjusted according to different clinical needs, helping to better optimize medical images.

[0085] Specifically, the adjustment control module 4 further includes an analysis unit and a determination unit, wherein the analysis unit is used to analyze the longitudinal height of the X-ray irradiation area of ​​the human body at a lying angle when the X-ray irradiates the injured or diseased part of the human body;

[0086] The determination unit is connected to the analysis unit and the judgment unit, and is used to determine the X-ray penetration distance of the human body according to the longitudinal height, and determine the standard X-ray intensity attenuation range based on the X-ray penetration distance of the human body.

[0087] In the specific implementation process, when the X-ray penetration distance T of the human body is 0cm<T≤20cm, the corresponding standard X-ray intensity attenuation range P is 90%<P<100%; when the X-ray penetration distance T of the human body is between 20cm<T≤30cm, the corresponding standard X-ray intensity attenuation range P is 85%<P≤90%; when the X-ray penetration distance T of the human body is T>30cm, the corresponding standard X-ray intensity attenuation range P is 80%<P≤85%.

[0088] Specifically, the X-ray intensity is automatically adjusted according to the body characteristics of each patient, avoiding the problem of excessive radiation or insufficient dose, and achieving more accurate personalized dose control. By analyzing the longitudinal height of the X-ray irradiation area at the human body's lying angle, the system can more accurately determine the actual penetration distance of X-rays in the human body, further improving the accuracy of X-ray intensity regulation.

[0089] Specifically, the magnitude of the initial current is related to the distance that the X-ray penetrates the human body, and the adjustment control module 4 determines the magnitude of the initial current according to the distance that the X-ray penetrates the human body.

[0090] Specifically, I0=i+k*T, where I0 is the initial current size, i is the basic current, k is the proportional coefficient, and T is the distance at which the X-ray penetrates the human body. In the specific implementation process, i=50mA, k=2mA / cm. When the penetration distance is 20cm, the initial current size I0=50+2*20=90mA.

[0091] Specifically, determining the initial current size by the distance that X-rays penetrate the human body can provide a more accurate initial dose for each patient. This method ensures that the X-ray intensity can match the patient's body size from the beginning, greatly reducing the risk of over- or under-exposure, and can achieve a higher degree of standardization between different examinations, improving the comparability and consistency of examination results.

[0092] Specifically, the adjustment control module 4 also includes a control module for independently controlling the carbon nanotube array 12 in partitions. The carbon nanotube array 12 is divided into several independently controlled areas, and each area independently adjusts the excitation quantity of carbon nanotubes to adjust the initial current size.

[0093] Specifically, the carbon nanotube array 12 is divided into a number of independent grid areas. When the X-ray irradiation area is large and different areas require different X-rays, the adjustment control module 4 controls the initial current size in different areas according to the penetration distance of different parts.

[0094] Specifically, by dividing the carbon nanotube array 12 into independent grid areas, more refined control of X-ray emission can be achieved. This regional control method can adjust the X-ray intensity according to different body parts, ensuring that each part receives an appropriate amount of X-rays, which not only improves image quality but also reduces unnecessary radiation received by the human body and enhances human safety.
