Description

Technical Field

[0001] The present invention relates to the field of radiation imaging technology, and particularly to a multi-modal imaging device based on a cold cathode. Background Art

[0002] CT is a medical imaging technology that generates detailed images of the internal structure of the body by using X-rays to perform tomographic imaging on the human body. The basic principle of CT scanning is to use an X-ray beam to scan a specific thickness layer of the human body. CT images reflect the degree of X-ray absorption of organs and tissues in different grayscales, have high density resolution, and can clearly display soft tissue and bone structures.

[0003] Chinese Patent Publication No.: CN117694834A discloses a multi-modal fluorescence hyperspectral micro-CT imaging method and device. The device includes an X-ray CT scanning module, a staring type fast fluorescence hyperspectral imaging module, a high-resolution fluorescence hyperspectral imaging module, and an information processing unit. During the rotation and scanning process of the device, the X-ray CT scanning module collects CT images of the sample at multiple angles to restore the internal three-dimensional structure. At the same time, the staring type fast fluorescence hyperspectral imaging module and the high-resolution fluorescence hyperspectral imaging module collect the fluorescence hyperspectral data of the sample. The information processing unit registers the fluorescence hyperspectral data with the internal three-dimensional data of the sample to form a visual multi-modal fluorescence hyperspectral micro-CT model.

[0004] It can be seen that the prior art has the following problems: The scanning parameters are not adjusted according to the clarity of different image images to obtain a complete and clear scanning image. Summary of the Invention

[0005] To this end, the present invention provides a multi-modal imaging device based on a cold cathode to overcome the lack of adjustment of scanning parameters according to the clarity of different image images in the prior art to obtain a complete and clear scanning image.

[0006] To achieve the above object, the present invention provides a multi-modal imaging device based on a cold cathode, including,

[0007] An X-ray source module for generating X-rays that can penetrate the target tissue for imaging the target tissue;

[0008] A CT detection module for detecting the X-rays passing through the target tissue and converting them into electrical signals;

[0009] An ultrasonic detection module for assisting the CT detection module to acquire images;

[0010] An imaging module for processing the image data collected by the CT detection module and the ultrasonic detection module and displaying them as visual image images;

[0011] A storage module for saving standard parameters and standard image images during the imaging process;

[0012] A control module for controlling the power of the ultrasonic detection module according to the image clarity level collected by the ultrasonic detection module; and adjusting the power of the X-ray source module according to the proportion of similarity of each area in the secondary image image;

[0013] A data analysis module analyzes the initial image image to obtain a clarity comparison difference, determines the clarity level of the initial image image according to the clarity comparison difference, and judges whether to perform a secondary scan on the ultrasonic detection module according to the clarity level; based on performing a secondary scan, judges whether to adjust the power of the ultrasonic detection module according to the secondary scan result; obtains the similarity level of the secondary image image according to the similarity comparison result between the secondary image image and the preset standard image image, and judges whether to perform area analysis according to the similarity level of the secondary image image; determines the proportion of area similarity based on the area analysis result, and adjusts the power of the X-ray source module according to the proportion of area similarity.

[0014] Further, the imaging module generates an initial image image according to the data collected by the ultrasonic detection module, and the data analysis module compares the clarity of the preset standard image image in the storage module with the initial image image to obtain a clarity comparison difference, and determines the clarity level of the initial image image according to the clarity comparison difference.

[0015] Further, when the clarity difference of the initial image image is between the first image clarity difference and the second image clarity difference, the data analysis module determines that the ultrasonic detection module performs a secondary scan.

[0016] Further, the data analysis module judges whether to adjust the power of the ultrasonic detection module through the control unit according to the difference between the clarity of the secondary image image and the standard image clarity.

[0017] Further, the data analysis module compares the adjusted secondary image image with the preset standard image image in the storage module, classifies the similarity of the secondary image image according to the comparison result, and the similarity classification is the first-level similarity, the second-level similarity and the third-level similarity.

[0018] Further, the data analysis module judges whether to perform area analysis according to the similarity level of the secondary image image, and partitions the secondary image image according to the judgment result.

[0019] Further, the power of the X-ray source module is initially adjusted according to the proportion of similarity of each area.

[0020] Further, the control unit determines the scanning time of the X-ray source module according to the similarity between the image formed by the power X-ray source module after initial adjustment and the standard image.

[0021] Further, the data analysis module generates an X-ray scan evaluation value according to the similarity between the image formed by the X-ray source module and the standard image and the scanning time of the X-ray source module.

[0022] Further, the data analysis module determines the X-ray scan evaluation value for scanning according to the comparison result between the X-ray scan evaluation value and the preset standard X-ray scan evaluation value.

[0023] Compared with the prior art, the beneficial effect of the present invention is that the control module controls the ultrasonic detection module to perform scanning, the imaging module acquires an initial image, and the data analysis module obtains a clarity comparison result by comparing the initial image with the standard image stored in the storage unit. When the difference between the clarity of the standard image and the clarity of the initial image is less than the first image clarity difference, the clarity of the initial image is the first-level clarity, and the clarity of the initial image meets the requirements. The data analysis module analyzes its content to make a judgment to ensure that the clarity of the initial image can be used for image content analysis; when the difference between the clarity of the standard image and the clarity of the initial image is greater than or equal to the first image clarity difference and less than the second image clarity difference, the clarity of the initial image is the second-level clarity, and the control module controls the ultrasonic detection module to perform secondary scanning to check whether the difference between the clarity of the initial image and the standard clarity requires adjustment of the power of the ultrasonic detection device to eliminate the clarity difference, so as to avoid deviation in subsequent analysis of its image content due to insufficient clarity of the initial image.

[0024] Further, the data analysis module determines whether the ultrasonic detection module performs a secondary scan according to the clarity level of the initial image. It can exclude the difference between the clarity of the image caused by non-device reasons and the clarity of the standard image. When the clarity level of the initial image is the first-level clarity, the ultrasonic detection module does not perform a secondary scan, avoiding reducing the service life of the device due to the secondary scan and ensuring that the preset image clarity can be obtained. When the clarity level of the initial image is the second-level clarity, the ultrasonic detection module performs a secondary scan to obtain a secondary image. The data analysis module determines the difference between the clarity of the secondary image and the clarity of the standard image. If the difference between the clarity of the secondary image and the clarity of the standard image is greater than or equal to zero and less than the first image clarity difference, the data analysis module performs image content analysis on the secondary image. When the clarity of the initial image does not reach the preset clarity, the ultrasonic detection module performs a secondary scan, which can exclude the poor clarity of the image caused by non-device reasons and ensure that a sufficiently clear image can be obtained. When the difference between the clarity of the secondary image and the clarity of the standard image is greater than or equal to the first image clarity difference and less than or equal to the second image clarity difference, the control module controls the power of the ultrasonic detection module to be adjusted. When the clarity of the secondary image after the secondary scan of the ultrasonic detection module still does not reach the preset clarity, the data processing unit determines that the control unit controls the power of the ultrasonic detection module to be adjusted, ensuring that an image with a clarity meeting the standard can be obtained after three scans.

[0025] Further, when the difference between the clarity of the secondary image and the clarity of the standard image is greater than or equal to the first image clarity difference and less than or equal to the second image clarity difference, the control unit controls the power of the ultrasonic detection module to increase, which can ensure that the clarity of the scanned image meets the analysis standard of the data analysis module. If the adjusted power of the ultrasonic detection module is greater than zero and less than or equal to the maximum power of the ultrasonic detection module, the adjusted power of the ultrasonic detection module is selected as the scanning power for the first scan, ensuring that the ultrasonic detection module scans within the normal operating power range. If the adjusted power of the ultrasonic detection module is less than or equal to the maximum power of the ultrasonic detection module, the maximum power of the ultrasonic detection module is selected as the scanning power for this scan, avoiding damage to the device and shortening the service life due to the power of the ultrasonic detection module exceeding the set maximum operating power.

[0026] Furthermore, the data analysis module compares the adjusted secondary image with the preset standard image in the storage module to grade the similarity of the secondary image. When the similarity between the secondary image and the standard image is less than or equal to the similarity of the first-class image, the similarity between the secondary image and the standard image is the first-level similarity. The data analysis module does not perform regional analysis on the secondary image, which can ensure that the content of the secondary image is basically consistent with the content of the standard image after being analyzed by the data analysis module, and there is no need for further analysis. If the similarity between the secondary image and the standard image is greater than the similarity of the first-class image and less than or equal to the similarity of the second-class image, then the similarity between the secondary image and the standard image is the second-level similarity. In this case, the data analysis module performs regional analysis on the secondary image. When the similarity between the secondary image and the standard image is the second-level similarity, it indicates that some content in the secondary image does not match the standard image, and more detailed regional analysis is required to ensure the authenticity of the content of the secondary image. If the similarity between the secondary image and the standard image is greater than the similarity of the second-class image, then the similarity between the secondary image and the standard image is the third-level similarity. The data analysis module determines the content of the secondary image. When the similarity of the image is the third-level similarity, it means that the content of the image has a large gap with the content of the standard image and poor comparability. The data analysis module can directly analyze its image content.

[0027] Furthermore, the data analysis module determines whether to perform regional analysis based on the similarity level of the secondary image, which can better compare the image with the standard image and confirm the proportion of the partition areas with different similarities to the standard image, avoiding re-scanning the X-ray source module with the same power for different partition areas. If the proportion of the partition areas with different similarities in the secondary image is greater than or equal to the first area ratio and less than the second area ratio, the control module controls the X-ray source module to perform re-scanning with the first power, which can avoid wasting energy due to too low a proportion of the partition areas with different similarities in the secondary image using too high a power of the X-ray source module. If the proportion of the partition areas with different similarities in the secondary image is greater than the second area ratio, the control module controls the X-ray source module to perform re-scanning with the second power, which can ensure that the image is clearer when the X-ray source module performs re-scanning when the proportion of the partition area to the standard image is too high.

[0028] Further, the control unit adjusts the scanning time of the X-ray source module according to the similarity between the image formed by the power X-ray source module after the initial adjustment and the standard image. When the similarity between the image formed by the power X-ray source module after the initial adjustment and the standard image is low, a longer scanning time of the X-ray source module is required to ensure the accuracy of scanning. When the similarity between the image formed by the power X-ray source module after the initial adjustment and the standard image is high, a shorter scanning time of the X-ray source module is required to avoid the long-term operation of the X-ray source module, thereby shortening its service life.

[0029] Further, the data analysis module determines the X-ray scanning evaluation value for scanning according to the comparison result between the X-ray scanning evaluation value and the preset standard X-ray scanning evaluation value. If the X-ray scanning evaluation value is less than the first X-ray scanning evaluation value, the first X-ray scanning evaluation value is selected as the scanning evaluation value to avoid the inability to ensure the scanning result due to too small a scanning evaluation value. If the X-ray scanning evaluation value is greater than the second X-ray scanning evaluation value, the second X-ray scanning evaluation value is selected as the scanning evaluation value to avoid equipment damage caused by the X-ray source module using a higher scanning evaluation value.

[0047] This embodiment provides an operation process of a multi-modal imaging device based on a cold cathode, including the following steps:

[0048] Step S101, the ultrasonic detection module performs a primary scan to obtain initial image data.

[0049] Step S102, the imaging module forms an initial image according to the initial image data.

[0050] Step S103, the CT detection module performs a CT scan according to the clarity of the initial image.

[0051] Step S104, the data analysis module analyzes the clarity of the initial image to obtain the clarity level of the initial image, and judges whether the ultrasonic detection module performs a secondary scan according to the clarity level of the initial image.

[0052] Specifically, the imaging module generates an initial image according to the data collected by the ultrasonic detection module, and the data analysis module compares the clarity of a preset standard image in the storage unit with the initial image to obtain a clarity comparison difference, and determines the clarity level of the initial image according to the clarity comparison difference.

[0053] The imaging module generates an initial image according to the data collected by the ultrasonic detection module, and the data analysis module analyzes the initial clarity of the initial image as Qa.

[0054] The storage module sets the clarity of the standard image as Qb.

[0055] The data analysis module sets the first image clarity difference Q1 and the second image clarity difference Q2.

[0056] If the difference Qa - Qb between the clarity of the standard image and the clarity of the initial image is greater than or equal to zero and less than the first image clarity difference Q1, then the clarity of the initial image is the first-level clarity, and the data analysis module performs image content analysis on the initial image;

[0057] If the difference Qa - Qb between the clarity of the standard image and the clarity of the initial image is greater than or equal to the first image clarity difference and less than or equal to the second image clarity difference Q2, then the clarity of the initial image is the second-level clarity, and the control module controls the ultrasonic detection module to perform a secondary scan.

[0058] The control module controls the ultrasonic detection module to perform a scan, the imaging module acquires the initial image, and the data analysis module obtains a clarity comparison result by comparing the initial image with the standard image set in the storage unit. When the difference between the clarity of the standard image and the clarity of the initial image is less than the first image clarity difference, the clarity of the initial image is the first-level clarity, and the clarity of the initial image meets the requirements. The data analysis module analyzes its content to make a judgment to ensure that the clarity of the initial image can be used for image content analysis; when the difference between the clarity of the standard image and the clarity of the initial image is greater than or equal to the first image clarity difference and less than the second image clarity difference, the clarity of the initial image is the second-level clarity, and the control module controls the ultrasonic detection module to perform a secondary scan to check whether the difference between the clarity of the initial image and the standard clarity requires adjustment of the power of the ultrasonic detection device to eliminate the clarity difference, so as to avoid deviation in subsequent analysis of its image content due to insufficient clarity of the initial image.

[0059] Specifically, when the difference in the clarity of the initial image is between the first image clarity difference and the second image clarity difference, the data analysis module determines that the ultrasonic detection module performs a secondary scan.

[0060] When the clarity level of the initial image is the first-level clarity, the ultrasonic detection module does not perform a secondary scan;

[0061] When the clarity level of the initial image is the second-level clarity, the ultrasonic detection module performs a secondary scan to obtain a secondary image, and the data analysis module determines the difference between the clarity of the secondary image and the clarity of the standard image.

[0062] If the difference between the clarity of the secondary image and the clarity of the standard image is greater than or equal to zero and less than the first image clarity difference, then the data analysis module performs image content analysis on the secondary image;

[0063] If the difference between the clarity of the secondary image and the clarity of the standard image is greater than or equal to the first image clarity difference and less than or equal to the second image clarity difference, the control module controls the power of the ultrasonic detection module to be adjusted.

[0064] The data analysis module determines whether the ultrasonic detection module performs a secondary scan according to the initial image clarity level, and can exclude the difference between the clarity of the image and the clarity of the standard image caused by non-device reasons. When the initial image clarity level is the first-level clarity, the ultrasonic detection module does not perform a secondary scan, avoiding reducing the service life of the device due to the secondary scan, and can ensure that the preset image clarity is obtained; when the initial image clarity level is the second-level clarity, the ultrasonic detection module performs a secondary scan to obtain a secondary image, and the data analysis module determines the difference between the clarity of the secondary image and the clarity of the standard image. If the difference between the clarity of the secondary image and the clarity of the standard image is greater than or equal to zero and less than the first image clarity difference, the data analysis module performs image content analysis on the secondary image. When the clarity of the initial image does not reach the preset clarity, the ultrasonic detection module performs a secondary scan, which can exclude the poor clarity of the image caused by non-device reasons and ensure that a sufficiently clear image is obtained; when the difference between the clarity of the secondary image and the clarity of the standard image is greater than or equal to the first image clarity difference and less than or equal to the second image clarity difference, the control module controls the power of the ultrasonic detection module to be adjusted. When the clarity of the secondary image still does not reach the preset clarity after the ultrasonic detection module performs a secondary scan, the data processing unit determines that the control unit controls the power of the ultrasonic detection module to be adjusted to ensure that an image with a clarity meeting the standard is obtained after three scans.

[0065] Specifically, the data analysis module determines whether to adjust the power of the ultrasonic detection module through the control unit according to the difference between the clarity of the secondary image and the standard clarity.

[0066] The storage unit is provided with the initial power Wa of the ultrasonic detection module and the maximum power Wb of the ultrasonic detection module.

[0067] When the difference between the clarity Qc1 of the secondary image and the clarity Qb of the standard image is greater than or equal to the first image clarity difference and less than or equal to the second image clarity difference, the data analysis module analyzes the difference between the clarity of the secondary image and the initial image clarity.

[0068] The control unit adjusts the power of the ultrasonic detection module according to the analysis result.

[0069] The power of the adjusted ultrasonic detection module is Wa1, and Wa1 = Wa + (Qb - Qc1) × e1, where e1 is the influence compensation parameter of the difference between the clarity of the secondary image and the clarity of the standard image on the power of the adjusted ultrasonic detection module.

[0070] If the power Wa1 of the adjusted ultrasonic detection module is greater than zero and less than or equal to the maximum power Wb of the ultrasonic detection module, select the power Wa1 of the adjusted ultrasonic detection module as the scanning power for one scan.

[0071] If the power Wa1 of the adjusted ultrasonic detection module is less than or equal to the maximum power Wb of the ultrasonic detection module, select the maximum power Wb of the ultrasonic detection module as the scanning power for one scan.

[0072] When the difference between the clarity of the secondary image and the clarity of the standard image is greater than or equal to the first image clarity difference and less than or equal to the second image clarity difference, the control unit controls the power of the ultrasonic detection module to increase, which can ensure that the clarity of the scanned image meets the analysis standard of the data analysis module. If the power of the adjusted ultrasonic detection module is greater than zero and less than or equal to the maximum power of the ultrasonic detection module, select the power of the adjusted ultrasonic detection module as the scanning power for one scan to ensure that the ultrasonic detection module scans within the normal operating power range; if the power of the adjusted ultrasonic detection module is less than or equal to the maximum power of the ultrasonic detection module, select the maximum power of the ultrasonic detection module as the scanning power for this scan to avoid damage to the equipment and shortening of the service life caused by the power of the ultrasonic detection module exceeding the set maximum operating power.

[0073] Specifically, the data analysis module compares the adjusted secondary image with the preset standard image in the storage module, and classifies the similarity of the secondary image according to the comparison result. The similarity classification is the first - level similarity, the second - level similarity, and the third - level similarity.

[0074] The storage unit is set with a first - class image similarity L1 and a second - class image similarity L2.

[0075] The data analysis module analyzes the similarity between the secondary image and the preset standard image in the storage module to obtain the similarity La between the secondary image and the standard image.

[0076] If the similarity La between the secondary image and the standard image is less than or equal to the first - class image similarity L1, then the similarity between the secondary image and the standard image is the first - level similarity, and the data analysis module does not perform regional analysis on the secondary image.

[0077] If the similarity La between the secondary image and the standard image is greater than the similarity L1 of the first-class image and less than or equal to the similarity L2 of the second-class image, the similarity between the secondary image and the standard image is the second-class similarity, and the data analysis module performs regional analysis on the secondary image;

[0078] If the similarity La between the secondary image and the standard image is greater than the similarity L2 of the second-class image, the similarity between the secondary image and the standard image is the third-class similarity, and the data analysis module determines the content of the secondary image.

[0079] The data analysis module compares the adjusted secondary image with the preset standard image in the storage module to grade the similarity of the secondary image according to the comparison result. When the similarity between the secondary image and the standard image is less than or equal to the similarity L1 of the first-class image, the similarity between the secondary image and the standard image is the first-class similarity, and the data analysis module does not perform regional analysis on the secondary image, which can ensure that the content of the secondary image analyzed by the data analysis module is basically consistent with the content of the standard image and does not require further analysis; if the similarity between the secondary image and the standard image is greater than the similarity L1 of the first-class image and less than or equal to the similarity L2 of the second-class image, the similarity between the secondary image and the standard image is the second-class similarity, and the data analysis module performs regional analysis on the secondary image. When the similarity between the secondary image and the standard image is the second-class similarity, it means that some content of the secondary image does not match the standard image, and more detailed regional analysis is required to ensure the authenticity of the content of the secondary image; if the similarity between the secondary image and the standard image is greater than the similarity L2 of the second-class image, the similarity between the secondary image and the standard image is the third-class similarity, and the data analysis module determines the content of the secondary image. When the similarity of the image is the third-class similarity, it means that the content of the image has a large difference from the content of the standard image and the comparability is poor, and the data analysis module can directly analyze the content of the image.

[0080] Specifically, the data analysis module determines whether to perform regional analysis according to the similarity level of the secondary image and partitions the secondary image according to the judgment result.

[0081] Specifically, the power of the X-ray source module is initially adjusted according to the proportion of the similarity of each region.

[0082] When the similarity La between the secondary image and the standard image is greater than the similarity L1 of the first-class image and less than or equal to the similarity L2 of the second-class image, the analysis unit respectively acquires the current secondary image and the standard image, and performs zonal analysis on them. The sorting of each zonal area is first from right to left and then from top to bottom.

[0083] The zonal areas of the secondary image are: the first zonal area is A1, the second zonal area is A2,..., and the nth zonal area is An.

[0084] The zonal areas of the standard image are: the first standard zonal area is B1, the second standard zonal area is B2,..., and the nth standard zonal area is Bn.

[0085] The data analysis module acquires any zonal area Ai and any standard zonal area Bi, where i = 1, 2, 3,..., n.

[0086] Any zonal area Ai is compared with the corresponding standard zonal area Bi.

[0087] The storage unit is provided with a first area ratio H1 and a second area ratio H2.

[0088] When any zonal area Ai is compared with the corresponding standard zonal area Bi, the proportion of the different areas of the zonal image similarity in the secondary image is Ha.

[0089] If the proportion Ha of the different areas of the zonal image similarity in the secondary image is less than the first area ratio H1, the data analysis module analyzes the content of the zonal image of each area.

[0090] If the proportion Ha of the different areas of the zonal image similarity in the secondary image is greater than or equal to the first area ratio H1 and less than the second area ratio H2, the control module controls the X-ray source module to scan with the first power.

[0091] If the proportion Ha of the different areas of the zonal image similarity in the secondary image is greater than the second area ratio H2, the control module controls the X-ray source module to scan with the second power.

[0092] The data analysis module determines whether to perform regional analysis based on the similarity level of the secondary image. It can better compare the image with the standard image and confirm the proportion of the partition area with different similarity to the standard image, avoiding scanning different partition areas with the same power of the X-ray source module. If the proportion of the area with different similarity in the partition area of the secondary image is greater than or equal to the first area ratio and less than the second area ratio, the control module controls the X-ray source module to scan with the first power, which can avoid wasting energy due to too high power of the X-ray source module when the proportion of the area with different similarity in the partition area is too low. If the proportion of the area with different similarity in the partition area of the secondary image is greater than the second area ratio, the control module controls the X-ray source module to scan with the second power, which can ensure that the image is clearer when the X-ray source module performs a rescan when the proportion of the partition area to the standard image is too high.

[0093] Specifically, the control unit determines the scanning time of the X-ray source module according to the similarity between the image formed by the X-ray source module with the initially adjusted power and the standard image.

[0094] Specifically, the data analysis module generates an initial X-ray scan evaluation value based on the similarity between the image formed by the X-ray source module and the standard image and the scanning time of the X-ray source module.

[0095] Specifically, the data analysis module determines the preferred X-ray scan evaluation value for scanning according to the comparison result between the initial X-ray scan evaluation value and the preset standard X-ray scan evaluation value.

[0096] The similarity between the image formed by the X-ray source module with the initially adjusted power and the standard image is Lc for the control unit.

[0097] The scanning time Ta of the X-ray source module = P / Lc×e2, where P is a proportionality constant and e2 is the influence compensation parameter of the similarity between the image formed by the X-ray source module with the initially adjusted power and the standard image on the scanning time of the X-ray source module.

[0098] The initial X-ray scan evaluation value Fs, Fs = Lc×j1 + Ta×j2 + Fs1, where j1 is the influence compensation parameter of the similarity between the image formed by the X-ray source module with the initially adjusted power and the standard image on the X-ray scan evaluation value; j2 is the influence compensation parameter of the scanning time of the X-ray source module on the X-ray scan evaluation value.

[0099] The storage unit is provided with a first X-ray scan evaluation value F1 and a second X-ray scan evaluation value F2.

[0100] If the initial X-ray scan evaluation value Fs is less than the first X-ray scan evaluation value F1, then select the first X-ray scan evaluation value F1 as the preferred scan evaluation value;

[0101] If the X-ray scan evaluation value Fs is greater than or equal to the first X-ray scan evaluation value F1 and less than the second X-ray scan evaluation value F2, then select the X-ray scan evaluation value Fs as the scan evaluation value;

[0102] If the initial X-ray scan evaluation value Fs is greater than the second X-ray scan evaluation value F2, then select the second X-ray scan evaluation value F2 as the preferred scan evaluation value.

[0103] The control unit adjusts the scanning time of the X-ray source module according to the similarity between the image formed by the power X-ray source module after the initial adjustment and the standard image. It can ensure that when the similarity between the image formed by the power X-ray source module after the initial adjustment and the standard image is low, a longer scanning time of the X-ray source module is required for scanning to ensure the accuracy of scanning. When the similarity between the image formed by the power X-ray source module after the initial adjustment and the standard image is high, a shorter scanning time of the X-ray source module is required for scanning to avoid the X-ray source module working for a long time, thereby shortening its service life.

[0104] The data analysis module determines the preferred X-ray scan evaluation value for scanning according to the comparison result between the initial X-ray scan evaluation value and the preset standard X-ray scan evaluation value. If the initial X-ray scan evaluation value is less than the first X-ray scan evaluation value, then select the first X-ray scan evaluation value as the preferred scan evaluation value to avoid being unable to ensure the scanning result due to too small a scan evaluation value. If the initial X-ray scan evaluation value is greater than the second X-ray scan evaluation value, then select the second X-ray scan evaluation value as the preferred scan evaluation value to avoid damage to the equipment caused by the X-ray source module using a relatively high scan evaluation value.
