Description

Technical Field

[0001] This invention relates to the field of breast imaging technology, specifically to a vibration reduction and noise reduction device for breast imaging CT. Background Technology

[0002] Breast lesions are common gynecological diseases, and breast CT scans are a very important tool for early diagnosis and differentiation. When using breast imaging CT to examine breast lesions, the patient should lie face down in the center of the scanning table with the breasts naturally drooping and stretched out, which is conducive to the display and comparative localization of lesions.

[0003] In existing technologies, breast imaging CT and scanning beds are high-precision, high-sensitivity devices. Their operating environment has a significant impact on image quality and equipment lifespan. Vibration is one of the main factors affecting equipment performance. It may come from the ground, support frame, external environment, or the operation of the equipment itself. Vibration can cause slight shaking of the breast, resulting in more noise in the images captured by breast imaging CT. Noise can cause random brightness or grayscale fluctuations in the image, making the details of the image blurry and the edges unclear. Excessive noise may also mask the subtle features of lesions, affecting the identification of lesions. Summary of the Invention

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Combined with appendix Figure 1-7 In this embodiment, the vibration reduction and noise reduction device for breast imaging CT includes: a mounting base 300, on which a CT mounting assembly 500 is fixedly mounted at the top center; the CT mounting assembly 500 includes a slewing bearing 510 and a mounting frame 520, the slewing bearing 510 being used to drive the mounting frame 520 to rotate, and the mounting frame 520 being used to mount the breast imaging CT; four metal supports 400, each symmetrically fixedly mounted at the four corners of the top of the mounting base 300; a scanning bed assembly 200, including a mounting frame 210 and a scanning bed body 220, the scanning bed body 220 being fixedly mounted on the mounting frame 210, and the scanning bed body 220 being used to provide support for the patient; and four vibration damping pads 100, each fixedly mounted on the top of the metal supports 400, the tops of the vibration damping pads 100 being fixedly connected to the four corners of the bottom of the mounting frame 210.

[0048] Specifically, the patient lies face down on the scanning bed body 220, and the slewing bearing 510 is activated to drive the mounting frame 520 to rotate. The mounting frame 520 drives the breast imaging CT fixedly mounted on its top to rotate, thereby achieving the purpose of breast imaging scanning of the patient's breast. The metal support 400 is used to support the scanning bed assembly 200. The vibration generated by the patient lying face down on the fixed frame 210 and the vibration generated by the breast imaging CT when rotating are absorbed by the shock-absorbing pad 100, so that the patient can lie face down on the fixed frame 210 stably and avoid the vibration being transmitted to the patient lying face down on the fixed frame 210, which would cause motion shadows during breast imaging CT imaging. The mounting base 300 is used to install and support the metal support 400, the CT mounting assembly 500, the shock-absorbing pad 100 and the scanning bed assembly 200.

[0049] In this embodiment, a mounting pad 110 is fixedly connected to the bottom of the shock-absorbing pad 100, and mounting holes 111 are provided at the four corners of the top of the mounting pad 110; a second through-hole 401 is provided at the four corners of the top of the metal support 400, the second through-hole 401 matches the mounting hole 111, and the position of the second through-hole 401 corresponds to the position of the mounting hole 111; a third through-hole 402 is provided at the bottom of the metal support 400, and the metal support 400 is fixedly installed at one corner of the top of the mounting base 300 by bolts in the third through-hole 402.

[0050] Specifically, four metal support members 400 are fixedly installed at one corner of the top of the mounting base 300 by bolts in the through-holes 402 at their bottoms, so that the four metal support members 400 are symmetrically fixed at the four corners of the top of the mounting base 300. The shock-absorbing pad 100 is fixedly installed on the top of the metal support member 400 by four mounting holes 111 on the mounting pad 110 fixedly connected to its bottom and bolts in the four mounting holes 111, thereby realizing that the four shock-absorbing pads 100 are respectively fixedly installed on the top of the metal support member 400.

[0051] In this embodiment, the top of the shock-absorbing pad 100 is a flat portion; a fixing hole 120 is provided at the center of the flat portion at the top of the shock-absorbing pad 100; a fixing plate 211 is fixedly installed at each of the four corners of the bottom of the fixing frame 210, and a through opening 212 is provided at the top of each fixing plate 211. The through opening 212 matches the fixing hole 120. After the fixing frame 210 is placed on the top of the four shock-absorbing pads 100, the fixing frame 210 is fixedly installed on the four shock-absorbing pads 100 by bolts in the through opening 212 and the corresponding fixing hole 120; an L-shaped reinforcing plate 213 is fixedly installed on the top of the fixing plate 211, and the two ends of the L-shaped reinforcing plate 213 are fixedly connected to the two nearest inner walls of the fixing frame 210 respectively.

[0052] Specifically, the fixing plate 211 is fixedly mounted on the shock-absorbing pad 100 through its own through-hole 212 and the bolts installed in the through-hole 212, thereby fixing the fixing frame 210 on the top of the four shock-absorbing pads 100. At the same time, the tightening force of the bolts needs to be moderate to avoid excessive compression of the shock-absorbing pads 100. The scanning bed body 220 is fixedly mounted on the top of the fixing frame 210 through bolts and embedded parts. The L-shaped reinforcing plate 213 fixes the fixing plate 211 and the fixing frame 210 together, making the connection between the breast detection port 221 and the fixing frame 210 more secure and increasing the stability of the fixing plate 211.

[0053] In this embodiment, a receiving groove is provided on the top of the scanning bed body 220, and the receiving groove is in the shape of an arc-shaped depression from the edge to the center; a breast detection port 221 is provided at the lowest point of the center of the receiving groove on the top of the scanning bed body 220.

[0054] Specifically, the patient lies face down in the receiving slot at the top of the scanning bed body 220, and the patient's entire upper body can lie face down in the receiving slot. The shape of the receiving slot, which is concave from the edge to the center, can increase the patient's comfort when lying face down in the receiving slot. The diameter of the breast detection port 221 is larger than the diameter of the patient's breast, so that the patient's breast can be easily inserted into the breast detection port 221.

[0055] In this embodiment, the shock-absorbing pad 100 is made of a highly elastic material such as rubber, polyurethane, or composite material. These materials have good elasticity and deformation capacity. When vibration is transmitted to the shock-absorbing pad 100, the shock-absorbing pad 100 will undergo elastic deformation, converting vibration energy into heat energy between internal molecules, thereby reducing the transmission of vibration.

[0056] In this embodiment, the scanning bed body 220 is the direct contact interface between the patient and the equipment, and its stability is crucial to image quality. The shock-absorbing pad 100 is installed between the mounting bracket 210 and the metal support 400 to isolate vibration sources. Patient movement isolation: The patient's breathing, heartbeat, or involuntary movements may cause minor vibrations. The shock-absorbing pad absorbs these vibrations, preventing them from being transmitted to the mounting bracket 520 and the breast imaging CT scanner mounted on it. Smooth movement of the scanning bed body 220: The scanning bed body 220 may generate mechanical vibrations during movement. The shock-absorbing pad 100 buffers these vibrations, ensuring smooth movement and preventing frictional damage to the scanning bed body 220 during device movement.

[0057] In this embodiment, the slewing bearing 510 generates centrifugal force and mechanical vibration when it drives the mounting frame 520 and the breast imaging CT scanner to rotate. These vibrations are transmitted to the ground or the scanning bed body 220 through the mounting base 300 or the metal support 400. The vibration damping pad 100 effectively isolates the vibrations of the slewing bearing 510, the mounting frame 520, and the breast imaging CT scanner, preventing them from affecting image quality. Centrifugal force buffering: The vibration damping pad 100 absorbs the centrifugal force generated by the mounting frame 520 and the breast imaging CT scanner, reducing their impact on the metal support 400 and the scanning bed body 220. Reverse vibration transmission: The vibration damping pad 100 prevents the vibration of the mounting frame 520 from being transmitted to the scanning bed through the metal support 400, thereby protecting patient comfort, reducing imaging noise and motion shadows in the breast imaging CT scanner, and making the image clearer.

[0058] In this embodiment, ground vibrations in the hospital environment may be transmitted to the breast imaging CT and scanning bed body 220 through the mounting base 300 and metal support 400, affecting the stability of the equipment. The shock-absorbing pad 100 can isolate ground vibrations, ensuring the stability of the scanning bed body 220 and preventing the scanning bed body 220 from experiencing minor vibrations due to ground vibrations. The shock-absorbing pad 100 can absorb the impact energy transmitted from the ground, such as vibrations caused by the movement of a cart or the falling of an object. Even minor ground vibrations can be isolated by the shock-absorbing pad 100 through elastic absorption and damping effects, preventing the vibrations from being transmitted to the scanning bed body 220, thereby making the scanning bed body 220 more stable and keeping the breasts of patients lying on the scanning bed body 220 stable.

[0059] In this embodiment, the scanning bed body 220 needs to be placed in a level and stable environment. However, the hospital floor may be slightly uneven. The shock-absorbing pad 100 can play a certain adjustment role to help the scanning bed body 220 stay stable and avoid tilting or shaking due to ground problems.

[0060] Working principle: The patient lies face down on the scanning bed body 220. The slewing bearing 510 is activated, which drives the mounting frame 520 to rotate. The mounting frame 520 drives the breast imaging CT fixed on its top to rotate, thereby achieving the purpose of breast imaging scanning of the patient's breast. The metal support 400 is used to support the scanning bed assembly 200. The vibration generated by the patient lying face down on the fixed frame 210 and the vibration generated by the breast imaging CT when rotating are absorbed by the shock-absorbing pad 100, so that the patient can lie face down on the fixed frame 210 stably and avoid the vibration being transmitted to the patient lying face down on the fixed frame 210, which would cause motion shadows during breast imaging CT imaging. The mounting base 300 is used to install and support the metal support 400, the CT mounting assembly 500, the shock-absorbing pad 100 and the scanning bed assembly 200.

[0061] Four metal support members 400 are fixedly installed at one corner of the top of the mounting base 300 by bolts in the through-holes 402 at their bottoms, so that the four metal support members 400 are symmetrically fixed at the four corners of the top of the mounting base 300. The shock-absorbing pad 100 is fixedly installed on the top of the metal support member 400 by four mounting holes 111 on the mounting pad 110 fixedly connected to its bottom and bolts in the four mounting holes 111, thereby realizing that the four shock-absorbing pads 100 are respectively fixedly installed on the top of the metal support member 400.

[0062] The fixing plate 211 is fixedly mounted on the shock-absorbing pad 100 through its own through-hole 212 and the bolts installed in the through-hole 212, thereby fixing the fixing frame 210 on the top of the four shock-absorbing pads 100. At the same time, the tightening force of the bolts needs to be moderate to avoid excessive compression of the shock-absorbing pads 100. The scanning bed body 220 is fixedly mounted on the top of the fixing frame 210 through bolts and embedded parts. The L-shaped reinforcing plate 213 fixes the fixing plate 211 and the fixing frame 210 together, making the connection between the breast detection port 221 and the fixing frame 210 more secure and increasing the stability of the fixing plate 211.

[0063] The patient lies face down in the receiving slot at the top of the scanning bed body 220, and the patient's entire upper body can lie face down in the receiving slot. The shape of the receiving slot, which is concave from the edge to the center, can increase the patient's comfort when lying face down in the receiving slot. The diameter of the breast detection port 221 is larger than the diameter of the patient's breast, so that the patient's breast can be easily inserted into the breast detection port 221.

[0064] The vibration damping pad 100 is made of highly elastic materials such as rubber, polyurethane, or composite materials. These materials have good elasticity and deformation capacity. When vibration is transmitted to the vibration damping pad 100, the pad undergoes elastic deformation, converting vibration energy into intermolecular heat energy, thereby reducing vibration transmission. The scanning bed body 220 is the direct contact interface between the patient and the equipment, and its stability is crucial to image quality. The vibration damping pad 100 is installed between the mounting frame 210 and the metal support 400 to isolate vibration sources. Patient movement isolation: The patient's breathing, heartbeat, or involuntary movements may cause minor vibrations. The vibration damping pad can absorb these vibrations and prevent them from being transmitted to the mounting frame 520 and the breast imaging CT scanner mounted on the mounting frame 520. Smooth movement of the scanning bed body 220: The scanning bed body 220 may generate mechanical vibrations during movement. The vibration damping pad 100 can buffer these vibrations, ensuring smooth movement and avoiding frictional damage to the scanning bed body 220 when moving the device. When the slewing bearing 510 rotates the mounting frame 520 and the breast imaging CT, it generates centrifugal force and mechanical vibration. These vibrations are transmitted to the ground or the scanning bed body 220 through the mounting base 300 or the metal support 400. The vibration damping pad 100 effectively isolates the vibrations of the slewing bearing 510, the mounting frame 520, and the breast imaging CT, preventing them from affecting image quality. Centrifugal force buffering: The vibration damping pad 100 absorbs the centrifugal force generated by the mounting frame 520 and the breast imaging CT, reducing its impact on the metal support 400 and the scanning bed body 220. Reverse vibration transmission: The vibration damping pad 100 prevents the vibration of the mounting frame 520 from being transmitted to the scanning bed through the metal support 400, thereby protecting patient comfort, reducing imaging noise and motion shadows in the breast imaging CT, and making the image clearer. Ground vibrations in the hospital environment can be transmitted to the breast imaging CT scanner and scanning bed 220 through the mounting base 300 and metal support 400, affecting the stability of the equipment. The shock-absorbing pad 100 can isolate ground vibrations, ensuring the stability of the scanning bed 220 and preventing it from experiencing minor vibrations. The shock-absorbing pad 100 can absorb the impact energy transmitted from the ground, such as vibrations caused by the movement of a cart or falling objects. Even minor ground vibrations can be isolated by the shock-absorbing pad 100 through elastic absorption and damping effects, preventing the vibrations from being transmitted to the scanning bed 220. This makes the scanning bed 220 more stable, keeping the breasts of patients lying on the scanning bed 220 stable.
