Description

Technical Field

[0001] This utility model relates to the field of X-ray detection technology, specifically to an X-ray medical detection system. Background Technology

[0002] X-ray medical imaging systems are commonly used medical fluoroscopy devices. Using X-rays as a medium, they leverage the principle that X-rays have different penetrating power to different substances. When X-rays pass through the human body, the varying penetrability of different tissues creates images of varying brightness on the X-ray imaging device. Using this principle, doctors can accurately determine the location and condition of lesions within the body being examined.

[0003] During X-ray imaging, the area to be examined needs to be in contact with the surface of the object being examined to reduce the probability of displacement and ensure image quality. The image obtained on the imaging plane during X-ray imaging is magnified, and the degree of magnification is related to the distance between the surface of the object being examined and the area to be examined. Currently, in clinical practice, the distance between the area to be examined and the surface of the object being examined is usually determined visually. However, since there is often a certain error between visual estimation and actual parameters, this reduces the accuracy of measuring the physical parameters of the corresponding organs and abnormal tissues in the image, thus affecting the doctor's judgment.

[0043] Please see Figures 1 to 17 This utility model provides an X-ray medical detection system 100. By setting a distance measuring device 140 on the contact surface 111 of the object to be tested, the X-ray medical detection system 100 can realize the distance measurement between the detection part 200 of the object to be tested and the contact surface 111 of the object to be tested. This can improve the measurement accuracy of the actual physical parameters of the corresponding organs and abnormal tissues in the detection image of the X-ray medical detection system 100, which is conducive to doctors making accurate judgments.

[0044] Please see Figure 1 and Figure 3 The X-ray medical detection system 100 includes a test object contact surface 111, an X-ray source 120, a detector 130, a ranging device 140, and a control unit (not shown in the figure).

[0045] The contact surface 111 of the object under test contacts the detection area 200 of the object under test to locate the detection area 200. It should be noted that the object under test can be a living object, such as a patient, or any inanimate object requiring imaging and detection by the X-ray medical detection system 100. Optionally, in this embodiment, the object under test refers to a patient. The contact surface 111 of the object under test can be a single planar structure or multiple spaced planar units arranged on the same plane; the specific structure is not limited as long as it can achieve the positioning of the detection area 200 of the object under test.

[0046] An X-ray source 120 is positioned on one side of the contact surface 111 of the object under test, with the detection area 200 of the object under test located between the X-ray source 120 and the contact surface 111. The X-ray source 120 emits X-rays and can emit different types of light, such as fan-shaped, cone-shaped, or pencil-shaped rays. The specific type of light emitted depends on factors such as the position of the detection area 200 and the image quality required in actual use. A detector 130 is positioned on the other side of the contact surface 111, with the contact surface 111 located between the detection area 200 and the detector 130. The detector 130 receives the X-rays that have passed through the detection area 200. Furthermore, after receiving the X-rays, the detector 130 generates a detection image through signal conversion.

[0047] A ranging device 140 is disposed on the contact surface 111 of the object to be measured. The ranging device 140 includes a data measurement unit 141 and a data transmission unit (not shown in the figure). The data measurement unit 141 is used to measure the distance information between the contact surface 111 of the object to be measured and the detection part 200 of the object to be measured. It should be noted that the distance information here refers to the distance information between the contact surface 111 of the object to be measured and the detection part 200 of the object to be measured in the vertical direction, that is... Figure 1 and Figure 2The distance H1 is the value of the distance between the two objects. The data measurement unit 141 can be various ranging units. In one embodiment, the data measurement unit 141 can be an inductive ranging unit, such as a laser ranging structure, an infrared ranging structure, an ultrasonic ranging structure, etc. In another embodiment, the data measurement unit 141 can also be a telescopic ruler ranging unit. It should be noted that the data measurement unit 141 and the data transmission unit can be integrated into one unit, or the data measurement unit 141 and the data transmission unit can be separately arranged. The ranging device 140 can also include a housing (not shown in the figure), in which the data measurement unit 141, the data transmission unit, and other components are housed. The ranging device 140 is disposed on the contact surface 111 of the object to be measured, specifically, the data measurement unit 141 is disposed on the contact surface 111 of the object to be measured.

[0048] The data transmission unit is connected to the data measurement unit 141, and the data transmission unit can acquire the spacing information measured by the data measurement unit 141. The data transmission unit includes, but is not limited to, various communication modules such as a Bluetooth module. Optionally, in this embodiment, the data transmission unit is a Bluetooth module. The control unit is communicatively connected to the data transmission unit, and the communicative connection method can be a wired connection or a wireless connection, etc. The control unit of the X-ray medical detection system 100 can receive the spacing information sent by the data transmission unit. It should be noted that the specific method by which the data transmission unit acquires the spacing information measured by the data measurement unit 141, and the specific method by which the control unit and the data transmission unit can communicate, can be implemented with reference to existing technology and actual application scenarios, and this utility model is not limited in this respect. In order to better highlight the inventive points of this embodiment, this embodiment will not describe them in detail.

[0049] Please see Figure 1 and Figure 3 It should be noted that during normal use of the X-ray medical detection system 100, the distance H2 between the contact surface 111 of the object under test and the imaging plane 131 inside the detector 130 is a fixed value and is known. Therefore, given the distance information (i.e., the value of H1) between the contact surface 111 of the object under test and the detection area 200 of the object under test, the distance H3 between the detection area 200 of the object under test and the imaging plane 131 inside the detector 130 can be calculated. This allows the determination of the magnification of the detected image, enabling the accurate marking of the magnification on the image. Based on the magnification, the actual physical parameters of the corresponding organs and abnormal tissues on the detected image can be accurately measured.

[0050] The X-ray medical detection system 100 of this invention, by setting a distance measuring device 140 on the contact surface 111 of the object to be tested, can realize the measurement of the distance between the contact surface 111 of the object to be tested and the detection part 200 of the object to be tested. Compared with the visual method in the prior art, this method can improve the measurement accuracy of the distance between the contact surface 111 of the object to be tested and the detection part 200 of the object to be tested. In turn, when used for X-ray detection, it can improve the measurement accuracy of the physical parameters of the corresponding organs and abnormal tissues of the detection part 200 of the object to be tested on the detection image, which is conducive to doctors making accurate judgments. Meanwhile, since the ranging device 140 includes a data measurement unit 141 and a data transmission unit, the data measurement unit 141 is used to measure the distance information between the contact surface 111 of the object to be measured and the detection part 200 of the object to be measured; the data transmission unit is connected to the data measurement unit 141 and can acquire the distance information measured by the data measurement unit 141; the data transmission unit is communicatively connected to the control unit of the X-ray medical detection system 100 and can receive the distance information sent by the data transmission unit. Therefore, during the imaging process of the detector 130, the distance information between the contact surface 111 of the object to be measured and the detection part 200 of the object to be measured can be directly read through the control unit, so that the distance information can be automatically filled in during the imaging process of the detector 130, saving the manual input step, thereby improving the imaging efficiency of the X-ray medical detection system 100 and further ensuring the accuracy of the distance information input. In a variation of the implementation, a control module can be provided in the ranging device 140. The X-ray medical detection system 100 can read the distance information between the contact surface 111 of the object to be measured and the detection part 200 of the object to be measured through the control module, so as to realize the automatic input of the distance information. This utility model is not limited in this respect.

[0051] Please see Figures 4 to 6 In one embodiment of this utility model, the detector 130 includes a support column 131, a detector head (not shown in the figure), and a cover 132. The support column 131 is used for fixed connection to the ground or other supports. The detector head receives X-rays after passing through the detection part 200 of the object under test. The detector head is disposed inside the cover 132, and the cover 132 is connected to the support column 131. The cover 132 can be fixedly connected to the support column 131, or it can be adjustable along the height direction of the support column 131. The cover 132 has an approximately rectangular structure, and the side of the cover 132 facing the X-ray source 120 has a planar area, and the contact surface 111 of the object under test is formed on this planar area. A ranging device 140 (which may be a data measuring unit 141 in an embodiment) is mounted on the cover 132. The ranging device 140 can be directly mounted on the cover 132, or it can be indirectly mounted on the cover 132 through other mounting brackets. The specific installation position of the ranging device 140 on the cover 132 is not limited. Optionally, in this embodiment, the ranging device 140 is installed in the width direction of the cover 132 (e.g., ...). Figure 4On the wall on either side of the X1 axis (as shown in the image). With this configuration, when imaging a patient, the patient can lean the detection area against the cover 132 to achieve contact with the contact surface 111 of the object to be tested, and then the distance information between the contact surface 111 of the object to be tested and the detection area 200 of the object to be tested is measured by the data measurement unit 141.

[0052] Please see Figure 3 , Figure 7 and Figure 8 In one embodiment of this utility model, the X-ray medical detection system 100 further includes a bed 150. The X-ray source 120, the bed 150, and the detector 130 are arranged vertically in sequence, that is, the bed 150 is located above the detector 130 and below the X-ray source 120. The bed 150 can be a bed structure that is not connected to the detector 130 and is supported on the ground, or it can be a bed structure that is fixedly connected to the cover 132 of the detector 130. The contact surface 111 of the object to be measured is formed on the bed surface of the bed 150 facing the X-ray source 120. The ranging device 140 (which can be a data measuring unit 141 in the embodiment) is installed on the bed 150, specifically in the width direction of the bed 150 (e.g., ...). Figure 8 The device can be positioned on any side wall of the bed (as shown on the X2 axis) or at any location on the bed surface that will not affect imaging. This configuration allows for measurement of the distance between the contact surface 111 and the detection area 200 of the object being tested, even when the patient is lying flat for imaging. Please refer to [link to relevant documentation]. Figure 18 The bed surface of the bed 150 has a width of D and a length of 3L. In one embodiment, without affecting imaging, the ranging device 140 can be positioned in one-third of the area centered along the length of the entire bed surface (e.g., ...). Figure 18 Any location within the shaded area (as shown in the middle).

[0053] Please see Figure 1 and Figure 9 In another embodiment of this utility model, the X-ray medical detection system 100 further includes a body frame 110. The X-ray source 120, body frame 110, and detector 130 are arranged sequentially in a horizontal direction. The contact surface 111 of the object to be tested is formed on the surface of the body frame 110 facing the X-ray source 120. Specifically, the body frame 110 includes a seat 115 and a positioning part 116. The bottom surface of the seat 115 is supported on the ground, and the positioning part 116 is fixedly connected to the top of the seat 115 and located in the length direction of the seat 115 (e.g., ...). Figure 9One end of the positioning part 116 (shown on the X-axis). The positioning part 116 includes a support frame 1161 and a connecting plate 1162 connected to the support frame 1161. A standing part 117 is also provided on the top of the seat 115, and the standing part 117 is correspondingly provided with the connecting plate 1162. Along the length direction of the seat 115, the side surface of the connecting plate 1162 facing the standing part 117 forms a test object contact surface 111. When the test object stands on the standing part 117, the test object detection part 200 contacts the test object contact surface 111. The data measurement part 141 is installed in the width direction of the positioning part 116 (e.g., ...). Figure 9 On any side wall of the object (as shown by the Y-axis). With this setup, when the patient needs to stand for the test, they stand on the standing part 117 and place the part of the patient to be tested against the contact surface 111 of the object to be tested. In this way, the distance information between the contact surface 111 of the object to be tested and the detection part 200 of the object to be tested, i.e., the value of the distance H1, can be measured by the data measurement unit 141.

[0054] Please see Figure 9 In one embodiment of this utility model, the positioning frame 110 is provided with handrails 112. The handrails 112 can be provided on the connecting plate 1162 or on the support frame 1161. The handrails 112 can be provided on both sides of the connecting plate 1162, or only on one side. Preferably, in this embodiment, the handrails 112 are provided on the support frame 1161, and there are two handrails 112, respectively located on both sides of the positioning part 116 in the width direction.

[0055] The ranging device 140 (which may be the data measuring unit 141 in this embodiment) is movably connected to the handrail 112, and the moving direction of the ranging device 140 is consistent with the measuring direction of the distance H1. There are various possible movable connection methods. For example, a guide rail can be provided on the handrail 112, and a slider can be provided on the ranging device 140, such as a slider provided on the data measuring unit 141. The ranging device 140 is slidably connected to the handrail 112 by sliding the slider on the guide rail. Alternatively, snap-fit ​​slots can be provided at different positions on the handrail 112, and snap-fit ​​blocks can be provided on the ranging device 140, such as snap-fit ​​blocks provided on the data measuring unit 141. The movable connection of the ranging device 140 to the handrail 112 is achieved by snapping the snap-fit ​​blocks with the snap-fit ​​slots at different positions.

[0056] Optionally, in this embodiment, one ranging device 140 is provided, which is slidably connected to either of the two handrails 112. In other embodiments, two ranging devices 140 may also be provided, with one ranging device 140 on each handrail 112. The specific structure of the handrail 112 is not limited; for example, it can be a ring structure formed by bending a tube, or a straight tube structure extending in a straight line, etc.

[0057] Considering that when the subject is a patient, the distance H1 will change accordingly when the detection area 200 of the subject comes into contact with the contact surface 111 of the subject due to the different body postures of the patients. Since the measurement position of the ranging device 140 (which may be the data measurement unit 141 in the embodiment) on the handrail 112 needs to be consistent with the detection area 200 of the subject, it is necessary to adjust the measurement position of the ranging device 140 on the handrail 112. In this embodiment, by movably connecting the ranging device 140 to the handrail 112, the ranging device 140 can be moved along the measurement direction of the distance H1, that is, the position of the ranging device 140 on the handrail 112 can be adjusted, thereby better matching the subject with different body postures, so as to better meet the measurement requirements of the distance H1 of different body postures and / or different detection areas on the body frame 110.

[0058] It should be noted that in other embodiments, the ranging device 140 may not be mounted on the handrail 112. For example, it may be a connecting rod structure separately mounted on the support frame 1161, with the ranging device 140 movably connected to the connecting rod. This also allows for adjustable displacement of the ranging device 140 relative to the contact surface 111 of the object being measured, thereby meeting the measurement requirements of the distance H1 between objects of different body shapes standing on the body frame 110.

[0059] To ensure that the ranging device 140 (which may be the data measuring unit 141 in the embodiment) can move on the handrail 112 along the direction of the spacing H1, please refer to Figures 10 to 14 In one embodiment of this utility model, a first guide component 113 is provided between the ranging device 140 and the handrail 112 to guide the ranging device 140 to slide along the measuring direction of the distance H1. The first guide component 113 includes a slide groove 1122 and a slide rod 1123. The slide groove 1122 is disposed on the handrail 112 and along the length direction of the handrail 112 (e.g., ...). Figure 10 Extending from the X3 axis, the slide rod 1123 is inserted into the slide groove 1122 and can slide within the slide groove 1122. Specifically, both ends of the slide rod 1123 extend to the outside of the slide groove 1122, and one end of the slide rod 1123 is provided with a handle portion 1124 to facilitate the sliding of the slide rod 1123 along the slide groove 1122 by manipulating the handle portion 1124. The other end of the slide rod 1123 is connected to the data measurement unit 141. Pushing the slide rod 1123 to slide within the slide groove 1122 enables the movement between the ranging device 140 and the handrail 112. In this embodiment, the data measurement unit 141 is a sensing ranging unit 1411. In other embodiments, the data measurement unit 141 can also be other ranging units.

[0060] When a patient stands on the positioning frame 110 and needs to undergo X-ray imaging, the sliding rod 1123 is moved within the sliding groove 1122 by operating the handle 1124. This, in turn, causes the sensing distance measuring unit 1411 to slide along the handrail 112. When the transmitting end of the sensing distance measuring unit 1411 is aligned with the detection area 200 of the object being measured, the movement of the sliding rod 1123 within the sliding groove 1122 is stopped, thus completing the position adjustment of the sensing distance measuring unit 1411. This adjustment method is simple in structure, convenient to operate, and has low manufacturing costs. The transmitting end of the sensing distance measuring unit 1411 emits a detection signal towards the contact surface 111 of the object being measured, while the receiving end receives the reflected detection signal, thereby measuring the distance information between the detection area 200 of the object being measured and the contact surface 111 of the object being measured, i.e., the value of the distance H1.

[0061] In another embodiment of this utility model, please refer to Figures 15 to 17 A first guide component 113 is provided between the ranging device 140 (which may be a data measuring unit 141 in this embodiment) and the handrail 112 to guide the movement of the ranging device 140. The first guide component 113 includes a first guide rail 1131 and a first slider 1132 that matches the first guide rail 1131. The first guide rail 1131 is fixedly connected to the handrail 112, and the extension direction of the first guide rail 1131 is consistent with the measurement direction of the distance H1. The first slider 1132 is fixedly connected to the data measuring unit 141. In this embodiment, the data measuring unit 141 is a telescopic ruler ranging unit 1412, and the telescopic ruler ranging unit 1412 is fixedly connected to the first slider 1132. Specifically, the data measurement unit 141 includes a housing 14121 and a measuring ruler 14122 housed within the housing 14121. The measuring ruler 14122 is marked with graduations for measuring distances. The measuring ruler 14122 can be any structure that can be rolled up and stored within the housing 14121, such as a flexible measuring tape or a steel tape measure. The housing 14121 can be in various shapes, such as a cuboid or a cylinder, as long as it meets the storage requirements of the measuring ruler 14122.

[0062] The housing 14121 is slidably connected to the handrail 112, and the first slider 1132 is fixedly connected to the housing 14121. The first slider 1132 slides along the first guide rail 1131 to achieve a sliding connection between the housing 14121 and the handrail 112. The measuring ruler 14122 is telescopically connected to the housing 14121, and the telescopic direction of the measuring ruler 14122 is consistent with the measurement direction of the distance H1. The telescopic connection method of the measuring ruler 14122 to the housing 14121 is not limited. For example, a spring structure can be provided inside the housing 14121, and the measuring ruler 14122 is wound inside the housing 14121. During the stretching process of the measuring ruler 14122, the spring undergoes elastic deformation. When the measuring ruler 14122 is released, the spring returns to its original position, thereby driving the measuring ruler 14122 to retract into the housing 14121. Alternatively, the measuring scale 14122 can be wound around a spool and housed within the housing 14121. The housing 14121 is equipped with a lever connected to the spool; rotating the lever in different directions allows the measuring scale 14122 to be extended or retracted relative to the housing 14121. By configuring the housing 14121 and the measuring scale 14122, and making the measuring scale 14122 retractably connected relative to the housing 14121, it is possible to measure dimensions at different intervals H1, and a large measurement range can be easily obtained. Furthermore, the structure of this quantity measuring unit 141 is relatively simple, which helps to reduce procurement costs.

[0063] The first guide rail 1131 can take various forms, such as a V-shaped guide rail, a T-shaped guide rail, or a rectangular guide rail. Preferably, in this embodiment, the first guide rail 1131 is a rectangular guide rail, which has a simple shape and is easy to manufacture. The first guide assembly 113 can be provided in one set or multiple sets, specifically to meet the guiding requirements of the data measurement unit 141 sliding on the handrail 112. Optionally, please refer to... Figure 17 In this embodiment, the first guide component 113 is provided in two sets, along the width direction of the handrail 112. Figure 17 As shown in the W direction, two sets of first guide components 113 are symmetrically arranged on both sides of the handrail 112 in the width direction. Correspondingly, two first sliders 1132 and two first guide rails 1131 are also provided, with one first slider 1132 corresponding to one first guide rail 1131. This arrangement can form a uniform guiding force on both sides of the data measuring unit 141, thereby improving the sliding guidance accuracy of the data measuring unit 141 on the handrail 112. By setting the first guide components 113, the stability of the data measuring unit 141 sliding on the handrail 112 can be improved, reducing phenomena such as offset and lateral tilting during the sliding of the data measuring unit 141, so as to ensure the smooth movement of the data measuring unit 141 on the handrail 112.

[0064] Furthermore, in order to reduce the probability of displacement of the data measurement unit 141 during the measurement process, optionally, please refer to... Figure 15 and Figure 17 In one embodiment of this utility model, a locking assembly 114 is provided between the data measuring unit 141 and the handrail 112 to lock and fix the data measuring unit 141 and the handrail 112 together when the data measuring unit 141 is performing measurement. The locking method of the locking assembly 114 can be any locking method such as threaded locking, wedge clamp locking, or locking spring.

[0065] In one embodiment, please refer to Figure 17 The locking assembly 114 includes a screw 1141 and a screw hole 1142 disposed on the housing 14121. One end of the screw 1141 is threaded, and the screw 1141 is threadedly connected to the housing 14121. The threaded end of the screw 1141 extends into the screw hole 1142 and abuts against and presses against the wall of the handrail 112. The screw 1141 can abut against and press against any wall such as the upper wall or side wall of the handrail 112. In this embodiment, considering the stability of the locking of the screw 1141, the screw 1141 is disposed between the two sets of first guide assemblies 113, and the threaded end of the screw 1141 passes through the data measuring part 141 and abuts against and presses against the surface of the upper wall of the handrail 112. When the data measuring unit 141 is performing measurements, the screw 1141 can be tightened so that the end of the screw 1141 presses against the upper wall surface of the handrail 112, thus locking the data measuring unit 141 to the handrail 112. When the data measuring unit 141 needs to slide on the handrail 112, the screw 1141 is loosened in the opposite direction, causing the end of the screw 1141 to disengage from the upper wall surface of the handrail 112, releasing the lock between the data measuring unit 141 and the handrail 112, and allowing the data measuring unit 141 to slide freely on the handrail 112. By providing the locking assembly 114, the data measuring unit 141 and the handrail 112 can be locked together during measurement, thereby reducing the probability of displacement of the data measuring unit 141 during measurement, and thus improving the measurement accuracy and efficiency of the distance H1.

[0066] Considering the differences in detection point heights between different test objects, and the situation where multiple detection points exist for the same test object at different heights, please refer to [link to relevant documentation]. Figure 9 In one embodiment of this utility model, the armrest 112 is movably connected to the positioning frame 110, and the direction of the moving connection is the same as the height direction of the positioning frame 110 (e.g., ...). Figure 9 (As shown on the Z-axis). Multiple options are available for the movable connection method. In one embodiment, a second guide component 1121 is provided between the armrest 112 and the positioning frame 110 to guide the armrest 112 to move along the height direction of the positioning frame 110. The second guide component 1121 includes a second guide rail 11211 fixedly connected to the positioning frame 110 and a second slider 11221 sliding along the second guide rail 11211. The second slider 11221 is fixedly connected to the armrest 112.

[0067] Specifically, the second guide rail 11211 is fixedly connected to the support frame 1161, and the length direction of the second guide rail 11211 is consistent with the height direction of the positioning frame 110. The second slider 11221 is fixedly connected to the armrest 112, and the second slider 11221 slides along the second guide rail 11211, thereby realizing the movement of the armrest 112 along the height direction of the positioning frame 110. Since the data measuring unit 141 is provided on the armrest 112, when the armrest 112 moves along the height direction of the positioning frame 110, it can drive the data measuring unit 141 to move synchronously along the height direction of the positioning frame 110. Furthermore, in order to reduce the probability of the armrest 112 shifting along the height direction of the positioning frame 110 during the measurement process of the data measuring unit 141, in this embodiment, a locking structure can also be provided on the armrest 112 to lock and fix the armrest 112 and the positioning frame 110 together during the spacing measurement process.

[0068] It should be noted that, in other embodiments, the movable connection method can also be a gear and rack structure, with the rack disposed on the support frame 1161, and the length direction of the rack aligned with the height direction of the body frame 110. The gear is disposed on the armrest 112, and the gear meshes and drives along the length direction of the rack, thereby enabling the armrest 112 to move along the height direction of the body frame 110. By making the armrest 112 movably connected to the body frame 110 along its height direction, the position of the armrest 112 in the height direction of the body frame 110 can be adjusted, that is, the position of the data measurement unit 141 in the height direction of the body frame 110 can be adjusted. This allows the installation position of the data measurement unit 141 to meet the measurement needs of different detection part heights between different test objects, as well as the measurement needs of multiple detection parts of the same test object in different height directions.

[0069] Please see Figure 16 In one embodiment of this utility model, the ranging device 140 further includes a display screen 142, which is configured to display the distance information between the contact surface 111 of the object to be measured and the detection part 200 of the object to be measured. The display screen 142 can be directly embedded in the housing 14121, or it can be installed on the outer wall of the housing 14121 through other connecting parts. The display screen 142 can be of various types, such as a liquid crystal display panel or a light-emitting diode display screen. By setting up the display screen 142, the measurement results can be displayed intuitively, making it more convenient and faster to read the values ​​during measurement, and improving the measurement efficiency. At the same time, since it is no longer necessary to read the values ​​by visually aligning the scale, the reading results are more accurate, which helps to improve the accuracy of the distance measurement.

[0070] The X-ray medical detection system provided by this utility model can measure the distance between the contact surface of the object under test and the detection area of ​​the object by setting a distance measuring device on the contact surface of the object under test. Compared with the visual method in the prior art, this method can improve the measurement accuracy of the distance between the contact surface of the object under test and the detection area of ​​the object under test. In turn, it can improve the measurement accuracy of the physical parameters of the corresponding organs and abnormal tissues of the detection area of ​​the object under test in the detection image when used for X-ray detection, which is conducive to doctors making accurate judgments. At the same time, since the distance measuring device includes a data measurement unit, a data transmission unit, and a control unit, the data measurement unit is used to measure the distance information between the contact surface of the object under test and the detection area of ​​the object under test; the data transmission unit is connected to the data measurement unit and can acquire the distance information measured by the data measurement unit; the control unit is communicatively connected to the data transmission unit and can receive the distance information sent by the data transmission unit. Therefore, during the detector imaging process, the distance information between the contact surface of the object under test and the detection area of ​​the object under test can be directly read by the control unit, so that the distance information can be automatically filled in during the detector imaging process, saving the manual input step, thereby improving the imaging efficiency of the X-ray medical detection system and further ensuring the accuracy of the distance information input. Therefore, this utility model effectively overcomes some practical problems in the prior art, thus having high utilization value and significance.

[0071] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
