Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a magnetic resonance imaging device for breast detection. Background Art

[0002] During a breast MRI examination, the patient lies prone on the examination bed with both breasts hanging naturally in the center of the breast coil to maintain bilateral symmetry. The entire MRI examination takes about 30 minutes and the body cannot move during the entire process. The patient's cooperation and compliance are required to avoid blurred images. The risk of breast cancer increases with age, and most breast cancer patients are diagnosed after the age of 50.

[0003] After age 50, women tend to gradually gain weight, with significant fat accumulation around the waist and abdomen. When there's a lot of abdominal fat, lying prone can compress the abdomen, leading to breathing difficulties – a discomfort that's particularly pronounced when holding your breath during an examination. It can also compress abdominal organs, causing discomfort such as a feeling of fullness or slight pain. To address these issues, the present invention provides a magnetic resonance imaging device for breast examinations to address these needs. Summary of the Invention

[0017] In the above scheme, by setting up a support component and a detection component, the support component and the detection component are respectively arranged at the abdominal port and the detection port on the prone mat. The support component can not only be used by patients with thick abdominal fat, but also can be adapted according to the difference in the patient's own weight during the placement of the abdomen, so as to make it more convenient for the device to support and contain the abdomen and improve the comfort of the user; the detection component can not only adapt to patients with different breast sizes, but also ensure that the center of the breast is aligned with the center of the coil, ensuring that the entire breast tissue is located within the imaging field of view, thereby obtaining clearer and more accurate images.

[0020] By setting the positioning piece to cooperate with the soft coil, the sliding of the limit block causes the positioning piece to move synchronously, thereby driving the shape change of the soft coil. The soft coil slides inside the through hole to facilitate adapting to the shape change of the soft coil, ensuring that the central axis of the soft coil coincides with the center of the positioning piece, thereby ensuring that the breast center is aligned with the coil center, ensuring that the entire breast tissue is located within the imaging field of view, thereby obtaining clearer and more accurate images. Not only is the structure simple and ingenious, but the actual operation is convenient and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The magnetic resonance imaging device for breast examination provided by the present invention has high detection sensitivity and can detect early, subtle lesions, especially when the results of mammography (mammography) and ultrasound examinations are unclear or limited. Its operating principle is based on the nuclear magnetic resonance phenomenon, and high-resolution images are generated through steps such as magnetic fields, radio frequency pulses, and signal acquisition. The operating principle of magnetic resonance imaging is public as a prior art and is therefore not described in detail. In actual examination, there are requirements for the patient's positioning. The patient lies prone on the examination bed 2, with both breasts naturally hanging in the center of the breast coil to maintain bilateral symmetry. This position helps to ensure uniform distribution of breast tissue and reduce wrinkles and compression. The entire scanning process usually takes about 30 minutes, and the patient needs to remain still during the examination to avoid image blur.

[0040] By setting up a support component and a detection component, the support component and the detection component are respectively arranged at the abdominal port 6 and the detection port 5 on the prone mat 3. The support component can not only be used by patients with thick abdominal fat, but also can be adapted according to the difference in the patient's own weight during the placement of the abdomen, so as to make it more convenient for the device to support and contain the abdomen and improve the comfort of the user; the detection component can not only adapt to patients with different breast sizes, but also ensure that the center of the breast is aligned with the center of the coil, ensuring that the entire breast tissue is located within the imaging field of view, thereby obtaining clearer and more accurate images.

[0041] As an implementation method in this embodiment, Figures 1 to 5 As shown, the support assembly includes a supporting plate 11, the supporting plates 11 are distributed oppositely, the supporting plate 11 is penetrated with a uniformly distributed lower weakening groove 13 near the bottom, the supporting plate 11 is penetrated with a uniformly distributed upper weakening groove 14 near the center of the abdominal opening 6, the supporting plate 11 is penetrated with a uniformly distributed perforation 15 near the inner wall of the abdominal opening 6, the supporting plate 11 is a curved elastic structure, the supporting plate 11 is provided with a bending portion 12 near the top edge of the prone pad 3, the supporting plate 11 is an S-shaped structure near the top of the examination bed 2, and the upper weakening groove 14 is penetrated with a uniformly distributed upper weakening groove 14. The weakening groove 14 and the lower weakening groove 13 correspond to the two bending parts of the S-shaped structure respectively. The upper weakening grooves 14 on the oppositely distributed supporting plates 11 are all staggered and corresponding. The elastic band 16 corresponds one to one with the position of the lower weakening groove 13. The elastic band 16 is fixedly connected to the bottom of the lower weakening groove 13. The elastic band 16 passes through the lower weakening groove 13, the upper weakening groove 14 to the top of the perforation 15 in sequence. The free end of the elastic band 16 is fixedly connected to the same cushion 17. The outer contour size of the elastic band 16 is smaller than the inner wall size of the lower weakening groove 13, the upper weakening groove 14 and the perforation 15.

[0042] Specifically, the support plate 11 is made of high-strength plastic, and the support plate 11 is a curved elastic structure. The bottom of the support plate 11 is set on the top of the examination bed 2, and the bent portion 12 protrudes from the top of the prone pad 3 and has an outward curvature. The lower weakening groove 13 and the upper weakening groove 14 are respectively located at the S-shaped bend at the bottom of the support plate 11 (such as Figures 4 and 5 As shown in FIG, the support plate 11 is thinned. This arrangement makes it easier for the support plate 11 to bend and deform at the positions of the lower weakening groove 13 and the upper weakening groove 14 under the action of external force, and the lower weakening groove 13 and the upper weakening groove 14 on the support plate 11 distributed in opposite directions are staggered, and the spacing between adjacent lower weakening grooves 13 is smaller than the width of the lower weakening groove 13 (as shown in FIG. Figure 4 As shown in the figure), when the top of the support plate 11 is compressed and lowered by the patient's own weight, the oppositely distributed lower weakening grooves 13 gradually approach each other, and the staggered distribution setting provides the support plate 11 with more deformation ability, thereby adapting to patients with larger weight.

[0043] By setting the support plate 11, the S-shaped curved elastic structure at the bottom of the support plate 11, and the outward bending and widening of the upper bending portion 12, the S-shaped curved elastic structure is utilized. Such a structural setting makes the overall structure of the support plate 11 elastic. Under the elastic action, the support plate 11 can produce a downward displacement under the pressing action of the patient's own weight, and restore the deformation after the external force stops pressing. The integrated structure of the support plate 11 and the bending portion 12 provides a wider load-bearing capacity for obese people, improves comfort, and the overall structure is simpler and more clever, and is easy to produce and install and disassemble.

[0044] like Figures 3 and 4 As shown, the elastic band 16 fixedly connected to the bottom of the support plate 11 passes through the lower weakened groove 13 and the upper weakened groove 14 in sequence, and extends upward through the bottom of the perforation 15. The top of the evenly distributed elastic band 16 is fixedly connected to the same soft pad 17. A coil is provided on the soft pad 17, and the edges of the oppositely distributed soft pads 17 are fixedly connected with mutually matching Velcro, which is convenient for fixing the soft pad 17 to the back of the patient. Since there is also a coil on the back, the signal-to-noise ratio at the armpit will be relatively high. When breast cancer patients or When other patients have axillary lymph node metastasis and enlargement, better images can be collected. The elastic band 16 is elastic and can adapt to patients with different abdominal dimensions. When in use, after the patient lies down according to the body position, the handheld cushion 17 is pulled upward and fixed to the patient's back with Velcro. After the test is completed, the Velcro of the cushion 17 is loosened, and the elastic force of the elastic band 16 itself is used to shrink, and the cushion 17 is limited to the top of the perforation 15 to provide soft support for the bent portion 12 on the support plate 11 to improve the patient's comfort.

[0045] By setting the elastic band 16 and the soft pad 17 together, there are two states between the elastic band 16 and the soft pad 17: before use, the elastic band 16 is stored at the bottom of the support plate 11, and the soft pad 17 is placed against the bent portion 12 to provide soft support for the bent portion 12, which can provide the patient with a comfortable experience when lying down; when in use, the elastic band 16 is used to pull it upward for easy adjustment, so that the soft pad 17 can better fit the patient's back; during actual operation, the user can use the above two states to fix the patient's back, and this fixing method is not only simple to operate and efficient, but also suitable for patients with different abdominal dimensions.

[0046] As an implementation method in this embodiment, Figures 1 to 2 and Figures 6 to 8As shown, the detection component includes limit blocks 18 distributed oppositely inside the detection port 5, the two detection ports 5 are symmetrically arranged, the top of the limit block 18 is fixedly connected to the chest pad 19, the limit block 18 near the symmetrical center of the two detection ports 5 is fixedly connected to the inside of the detection port 5, and a screw 20 is threadedly connected on the inner wall away from the symmetrical center of the two detection ports 5, the end of the screw 20 is fixedly connected to the limit block 18, the bottom of the two limit blocks 18 is fixedly connected to a connecting rope 23, the center of the connecting rope 23 is fixedly connected to a positioning member 24, and the positioning member 24 is fixedly connected to a soft coil 25. The limit block 18 is an arc-shaped structure, and the outer contour curvature of the limit block 18 is adapted to the inner wall curvature of the detection port 5. A fixed block 21 is fixedly connected to one side of the limit block 18 fixedly connected to the screw 20. A through hole 22 is opened through the fixed block 21. The inner wall size of the through hole 22 is larger than the outer wall size of the soft coil 25. The top of the soft coil 25 is fixedly connected to the limit block 18 fixedly connected to the inner wall of the detection port 5, and the bottom of the soft coil 25 is fixedly connected to the positioning piece 24 through the through hole 22. The soft coil 25 is a conical spiral shape that is thick at the top and thin at the bottom. The connecting rope 23 is a soft rope body, and the central axis of the soft coil 25 corresponds to the center of the positioning piece 24.

[0047] Furthermore, the limit blocks 18 are distributed oppositely inside the detection port 5, one of which is fixedly connected to the inner wall of the detection port 5, and the other slides inside the detection port 5 through a screw 20. The spacing between the limit blocks 18 can be adjusted by rotating the screw 20. The specific structure and working principle of the screw 20 are disclosed as prior art, so they will not be described in detail. Since the bottom of the limit block 18 is fixedly connected to the same connecting rope 23, a positioning member 24 is fixedly connected to the center of the connecting rope 23, and the connecting rope 23 is a soft rope body, the movement of the limit block 18 causes the area formed between the limit blocks 18 to change, and the connecting rope 23 and the positioning member 24 also change synchronously. The positioning member 24 always corresponds to the central axis between the limit blocks 18. Since the top of the soft coil 25 is fixedly connected to the limit block 18 fixedly connected to the inner wall of the detection port 5, the bottom of the soft coil 25 passes through the through hole 22 and is fixedly connected to the positioning member 24. The soft coil 25 is in the shape of a conical spiral with a thick top and a thin bottom (such as Figures 6 to 8 As shown), the central axis of the soft coil 25 will correspond to the center of the positioning member 24, thereby ensuring that the center of the breast is aligned with the center of the coil, and ensuring that the entire breast tissue is within the imaging field of view, thereby obtaining a clearer and more accurate image. The density of the soft coil 25 is only indicated here, and the specific density requirements can be set in actual use.

[0048] By setting the positioning piece 24 to cooperate with the soft coil 25, the sliding of the limit block 18 causes the positioning piece 24 to move synchronously, thereby driving the shape change of the soft coil 25. The soft coil 25 slides inside the through hole 22 to facilitate adapting to the shape change of the soft coil 25, ensuring that the central axis of the soft coil 25 coincides with the center of the positioning piece 24, thereby ensuring that the breast center is aligned with the coil center, ensuring that the entire breast tissue is located within the imaging field of view, thereby obtaining a clearer and more accurate image. Not only is the structure simple and ingenious, but the actual operation is convenient and labor-saving.

[0049] The workflow of the technical solution provided by the present invention is as follows:

[0050] During use, the patient needs to remove all metal objects to avoid magnetic field interference, change into the examination clothes provided by the hospital, lie prone on the examination bed 2, expose the breasts, and make both breasts hang naturally between the limit blocks 18. The spacing between the limit blocks 18 can be adjusted by rotating the screw 20 so that the limit blocks 18 are close to the breasts but do not cause pressure on the breasts. The head is placed on the headrest 9, the arms are stretched upward along the curved edge 8 and placed on both sides of the head, the abdomen is placed on the top of the support plate 11, and the leg pad 10 is on the inclined surface 7 to ensure the patient's comfort and reduce pressure. The S-shaped curved elastic structure at the bottom of the support plate 11 is combined with the outward bending and widening of the upper bending portion 12. The S-shaped curved elastic structure makes the overall structure of the support plate 11 elastic. Under the elastic action, the support plate 11 can be displaced downward under the pressure of the patient's own weight. When the top of the support plate 11 is compressed by the patient's own weight and lowered in height, the oppositely distributed lower weakening grooves 13 gradually approach each other, and the staggered distribution setting provides the support plate 11 with more deformation ability, thereby adapting to patients with larger weight.

[0051] After the patient lies down according to the body position, the handheld soft pad 17 is pulled upward and fixed to the patient's back with Velcro. Since there is also a coil on the back, the signal-to-noise ratio in the armpit will be relatively high. When breast cancer patients or other patients have axillary lymph node metastasis and enlargement, better images can be collected.

[0052] After the test is completed, the Velcro of the cushion 17 is loosened, and the elastic band 16 is stored to the bottom of the support plate 11 by its own elastic force, and the cushion 17 is limited to the top of the perforation 15 to provide soft support for the bent portion 12 on the support plate 11 to improve the patient's comfort. The spacing between the limit blocks 18 can be adjusted by rotating the screw 20 to adapt to patients with different breast sizes. Since the bottom of the limit block 18 is fixedly connected to the same connecting rope 23, a positioning piece 24 is fixedly connected to the center of the connecting rope 23. The connecting rope 23 is a soft rope body, and the movement of the limit block 18 makes the space between the limit blocks 18 As the range of the formed area changes, the connecting rope 23 and the positioning piece 24 also change synchronously. The positioning piece 24 always corresponds to the central axis between the limit blocks 18. Since the top of the soft coil 25 is fixedly connected to the limit block 18 fixedly connected to the inner wall of the detection port 5, the bottom of the soft coil 25 passes through the through hole 22 and is fixedly connected to the positioning piece 24. The soft coil 25 is in a conical spiral shape that is thick at the top and thin at the bottom. The central axis of the soft coil 25 will correspond to the center of the positioning piece 24, thereby ensuring that the center of the breast is aligned with the center of the coil, ensuring that the entire breast tissue is located within the imaging field of view, thereby obtaining a clearer and more accurate image.

[0053] During the scanning process, the patient needs to remain still to avoid respiratory movement or body shaking that affects the image quality. Correct body positioning can reduce skin wrinkles and motion artifacts, and improve diagnostic accuracy. This device can not only be used by patients with thick abdominal fat, but also can be adapted according to the patient's own weight differences during placement on the abdomen, making it more convenient for the device to support and accommodate the abdomen and improve the user's comfort; it can also adapt to patients with different breast sizes, ensuring that the breast center is aligned with the coil center, and ensuring that the entire breast tissue is within the imaging field of view, thereby obtaining clearer and more accurate images.

To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
