Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a magnetic resonance imaging device for breast cancer detection. Background Technology

[0002] During a breast MRI scan, the patient lies prone on the examination table with both breasts hanging naturally in the center of the breast coil, maintaining bilateral symmetry. The entire MRI scan takes about 30 minutes, and the patient must not move throughout the process. This requires a high degree of cooperation and compliance from the patient to avoid blurry images. The risk of developing breast cancer increases with age, and most breast cancer patients are diagnosed after the age of 50.

[0003] After the age of 50, women's weight often gradually increases, especially with significant fat accumulation in the waist and abdomen. When there is a lot of abdominal fat, the prone position may not only compress the abdomen, causing difficulty breathing, especially when holding one's breath to cooperate with the examination, this discomfort will be more pronounced. Moreover, it will put pressure on abdominal organs, such as abdominal fullness or mild pain, leading to discomfort. Therefore, based on the above problems, the present invention provides a magnetic resonance imaging device for breast examination to meet the needs. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a magnetic resonance imaging device for breast examination. By setting up a support component and a detection component, the support component can not only be used by patients with thick abdominal fat, but also adapt to the patient's weight during placement on the abdomen, thus making it easier for the device to support and contain the abdomen and improving user comfort. 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 within the imaging field of view, thereby obtaining clearer and more accurate images. Through the above settings, the problem of low comfort of existing examination beds for patients with thick abdominal fat can be solved.

[0008] Optionally, the support plate is a curved elastic structure, and the support plate is provided with a bent part near the top edge of the prone pad. The support plate near the top of the examination bed is an S-shaped structure. The upper weakening groove and the lower weakening groove correspond to the two bends of the S-shaped structure, respectively. The upper weakening grooves on the opposing support plates are all staggered.

[0009] Optionally, the elastic band corresponds one-to-one with the lower weakening groove, the elastic band is fixedly connected to the bottom of the lower weakening groove, the elastic band passes through the lower weakening groove and the upper weakening groove in sequence to the top of the perforation, and the free end of the elastic band is fixedly connected to the same soft pad.

[0010] Optionally, the outer contour dimension of the elastic band is smaller than the inner wall dimensions of the lower weakening groove, the upper weakening groove, and the perforation.

[0011] Optionally, the prone mat has symmetrically arranged detection ports near the abdominal opening, a breathing port is provided through one end of the prone mat, a headrest is fixedly connected to the top of the breathing port, an arc-shaped edge is symmetrically arranged near the breathing port of the prone mat, and a slope is provided at the other end of the prone mat, on which a leg pad is provided.

[0012] Optionally, the detection component includes limiting blocks distributed opposite each other inside the detection port. A chest pad is fixedly connected to the top of the limiting block. The limiting block near the center of the prone mat is fixedly connected to the interior of the detection port. A screw is threadedly connected to the inner wall of the detection port away from the center of the prone mat. The screw is fixedly connected to the limiting block away from the center of the prone mat. A connecting rope is fixedly connected to the bottom of the limiting block. A positioning element is fixedly connected to the center of the connecting rope. A flexible coil is fixedly connected to the positioning element.

[0013] Optionally, the limiting block has an arc-shaped structure, and the outer contour arc of the limiting block is adapted to the inner wall arc of the detection port. A fixing block is fixedly connected to one side of the limiting block, which is fixedly connected to the screw. A through hole is provided on the fixing block, and the inner wall size of the through hole is larger than the outer wall size of the flexible coil.

[0014] Optionally, the top of the flexible coil is fixedly connected to the limiting block fixedly connected to the inner wall of the detection port, the bottom of the flexible coil passes through the through hole and is fixedly connected to the positioning member, and the flexible coil is in the shape of a conical spiral that is thicker at the top and thinner at the bottom.

[0015] Optionally, the connecting rope is a flexible rope, and the central axis of the flexible coil corresponds to the center of the positioning member.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up a support component and a detection component, which are respectively set at the abdominal opening and detection opening on the prone mat, the support component can not only be used by patients with thick abdominal fat, but also adapt to the patient's weight difference during the placement of the abdomen, thus making it easier for the device to support and contain the abdomen and improve the user's comfort. 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 within the imaging field of view, thereby obtaining clearer and more accurate images.

[0018] By incorporating a support plate with an S-shaped curved elastic structure at its bottom, combined with the outward bending of the bend, the support plate becomes elastic. This elastic structure allows the support plate to shift downwards under the pressure of the patient's own weight and recover its deformation after the pressure is released. The integrated structure of the support plate and the bend provides greater load-bearing capacity for obese individuals, improving comfort. The overall structure is simpler, more ingenious, and easier to manufacture, install, and disassemble.

[0019] By using an elastic band and a soft pad, there are two states between them: Before use, the elastic band is stored at the bottom of the support plate, and the soft pad is placed against the bend to provide soft support for the bend, providing a comfortable experience for the patient when lying down. When in use, the elastic band is pulled upwards for easy adjustment, allowing the soft pad to better fit the patient's back. In actual operation, the user can use the above two states to fix the patient's back. Moreover, this fixation method is not only simple to operate and efficient, but also suitable for patients with different abdominal dimensions.

[0020] By setting up a positioning component that works in conjunction with the soft coil, the sliding of the limiting block causes the positioning component to move synchronously, thereby driving the shape change of the soft coil. The soft coil slides inside the through hole to easily adapt to the shape change of the soft coil, ensuring that the central axis of the soft coil coincides with the center of the positioning component, thus 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. It is not only simple and ingenious in structure, but also convenient and labor-saving in actual operation. Attached Figure Description

[0038] like Figures 1 to 8 As shown, an embodiment of the present invention provides a magnetic resonance imaging device for breast examination, including a scanner 1, an examination bed 2 slidably connected to the top of the scanner 1, a prone pad 3 fixedly connected to the top of the examination bed 2, an abdominal opening 6 on the top of the prone pad 3, a support component fixedly connected inside the abdominal opening 6, the support component being used to improve the abdominal support of the user, and the support component being connected to the prone pad 3; a detection component being used to assist users with different breast sizes, the detection component being connected to the prone pad 3, a detection port 5 symmetrically opened near the abdominal opening 6 on the prone pad 3, a breathing port 4 penetrating through one end of the prone pad 3, a headrest 9 fixedly connected to the top of the breathing port 4, an arc-shaped edge 8 symmetrically opened near the breathing port 4 on the prone pad 3, and a slope 7 on the other end of the prone pad 3, on which a leg pad 10 is provided.

[0039] The magnetic resonance imaging device for breast examination provided by this invention has high detection sensitivity and can detect early and minute lesions, especially when the results of mammography (mammography) and ultrasound examination are unclear or have limitations. Its working principle is based on the phenomenon of nuclear magnetic resonance, which generates high-resolution images through magnetic fields, radio frequency pulses and signal acquisition. The working principle of magnetic resonance imaging is disclosed as prior art and will not be described in detail. In actual examination, there are requirements for the patient's body position. The patient lies prone on the examination table 2, with both breasts hanging naturally in the center of the breast coil, maintaining bilateral symmetry. This position helps to ensure the uniform distribution of breast tissue and reduce wrinkles and compression. The entire scanning process usually takes about 30 minutes. The patient should remain still during the examination to avoid image blurring.

[0040] By setting up a support component and a detection component, which are respectively located at the abdominal opening 6 and the detection opening 5 on the prone pad 3, the support component can not only be used by patients with thick abdominal fat, but also adapt to the patient's weight during placement, thus making it easier for the device to support and contain the abdomen and improving user comfort. 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 within the imaging field of view, thereby obtaining clearer and more accurate images.

[0041] As one implementation method in this embodiment, such as Figures 1 to 5 As shown, the support assembly includes a support plate 11, which is distributed opposite to each other. The support plate 11 has evenly distributed lower weakening grooves 13 extending through it near the bottom, and evenly distributed upper weakening grooves 14 extending through it near the center of the abdominal opening 6. The support plate 11 also has evenly distributed perforations 15 extending through it near the inner wall of the abdominal opening 6. The support plate 11 has a curved elastic structure. A bending portion 12 is provided near the top edge of the prone pad 3. The support plate 11 has an S-shaped structure near the top of the examination bed 2, with upper weakening... The lower weakening groove 14 and the upper weakening groove 13 correspond to the two bends of the S-shaped structure, respectively. The upper weakening grooves 14 on the opposing support plates 11 are all staggered. The elastic band 16 corresponds to 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 and the upper weakening groove 14 in sequence to the top of the perforation 15. The free end of the elastic band 16 is fixedly connected to the same soft pad 17. The outer contour dimension of the elastic band 16 is smaller than the inner wall dimension 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 has a curved elastic structure. The bottom of the support plate 11 is set on the top of the examination bed 2, the bent part 12 protrudes from the top of the prone pad 3 and has an outward curvature, and 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 (e.g., Figures 4 to 5 As shown), the support plate 11 is thinned. This design makes the support plate 11 more susceptible to bending deformation under external force at the positions of the lower weakening groove 13 and the upper weakening groove 14. Furthermore, the lower weakening grooves 13 and the upper weakening grooves 14 on the opposing support plate 11 are staggered, and the spacing between adjacent lower weakening grooves 13 is smaller than the width of the lower weakening groove 13 (e.g., ...). Figure 4 As shown, when the top of the support plate 11 is compressed and lowered by the patient's own weight, the opposing lower weakening grooves 13 gradually approach each other and provide the support plate 11 with more deformation capacity through the staggered distribution, thereby adapting to patients with larger weights.

[0043] By setting up a support plate 11, with its S-shaped curved elastic structure at the bottom, combined with the outward bending and widening of the bending part 12, the support plate 11 becomes elastic. Under the action of elasticity, the support plate 11 can be displaced downward under the pressure of the patient's own weight and recover its deformation after the external force is released. The integrated structure of the support plate 11 and the bending part 12 provides a wider load-bearing capacity for obese people, improves comfort, and makes the overall structure simpler and more ingenious, as well as easy to manufacture, install, and disassemble.

[0044] like Figures 3 to 4 As shown, the elastic band 16, fixedly connected to the bottom of the support plate 11, passes through the lower weakening groove 13 and the upper weakening groove 14 in sequence, extends upward through the bottom of the perforation 15, and the top of the evenly distributed elastic band 16 is fixedly connected to the same soft pad 17. The soft pad 17 is provided with a coil, and the edges of the opposing soft pads 17 are fixedly connected with mutually cooperating Velcro, which makes it easy to fix the soft pad 17 to the back of the patient. Since there is also a coil on the back, the signal-to-noise ratio will be relatively high in the armpit. When breast cancer patients or When other patients have axillary lymph node metastasis and swelling, better images can be acquired. The elastic band 16 is elastic and can adapt to patients with different abdominal dimensions. When using it, after the patient lies face down, hold the soft pad 17 and pull it upwards. It is fixed to the patient's back with Velcro. After the test is completed, release the Velcro of the soft pad 17. The elastic band 16 contracts by its own elasticity, and the soft pad 17 is limited to the top of the perforation 15, providing soft support to the bend 12 on the support plate 11 to improve the patient's comfort.

[0045] By setting up the elastic band 16 and the soft pad 17 in combination, 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 part 12 to provide soft support for the bent part 12, which can provide a comfortable experience for the patient when lying down. When in use, the elastic band 16 is pulled upwards for easy adjustment, so that the soft pad 17 fits better against the patient's back. In actual operation, the user can use the above two states to fix the patient's back. Moreover, this fixation method is not only simple to operate and efficient, but also applicable to patients with different abdominal dimensions.

[0046] As one implementation method in this embodiment, such as Figures 1 to 2 and Figures 6 to 8As shown, the detection assembly includes limiting blocks 18 distributed opposite each other inside the detection ports 5. The two detection ports 5 are symmetrically arranged. A breast pad 19 is fixedly connected to the top of the limiting blocks 18. The limiting blocks 18 near the center of symmetry of the two detection ports 5 are fixedly connected to the interior of the detection ports 5. A screw 20 is threadedly connected to the inner wall away from the center of symmetry of the two detection ports 5. The end of the screw 20 is fixedly connected to the limiting blocks 18. A connecting rope 23 is fixedly connected to the bottom of the two limiting blocks 18. A positioning element 24 is fixedly connected to the center of the connecting rope 23. A flexible coil 25 is fixedly connected to the positioning element 24. The limiting block 18 has an arc-shaped structure. The outer contour arc of the limiting block 18 matches the inner wall arc of the detection port 5. A fixing block 21 is fixedly connected to one side of the limiting block 18, which is fixedly connected to the screw 20. A through hole 22 is opened through the fixing 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 limiting block 18, which is fixedly connected to the inner wall of the detection port 5. The bottom of the soft coil 25 is fixedly connected to the positioning member 24 through the through hole 22. The soft coil 25 is a conical spiral shape that is thicker at the top and thinner at the bottom. The connecting rope 23 is a soft rope. The central axis of the soft coil 25 corresponds to the center of the positioning member 24.

[0047] Furthermore, regarding the limiting blocks 18 distributed inside the detection port 5, one is fixedly connected to the inner wall of the detection port 5, and the other slides inside the detection port 5 via a screw 20. The spacing between the limiting 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 and will not be elaborated further. Since the bottom of the limiting blocks 18 is fixedly connected to the same connecting rope 23, and a positioning element 24 is fixedly connected to the center of the connecting rope 23, and the connecting rope 23 is a flexible rope, the movement of the limiting blocks 18 changes the area formed between them. The connecting rope 23 and the positioning element 24 also change synchronously. The positioning element 24 always corresponds to the central axis between the limiting blocks 18. Since the top of the flexible coil 25 is fixedly connected to the limiting block 18 fixedly connected to the inner wall of the detection port 5, and the bottom of the flexible coil 25 passes through the through hole 22 and is fixedly connected to the positioning element 24, the flexible coil 25 has a conical spiral shape that is thicker at the top and thinner at the bottom (e.g., ...). 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 that the entire breast tissue is within the imaging field of view, thus obtaining a clearer and more accurate image. The density of the soft coil 25 is only shown here, and the specific density requirements can be set in actual use.

[0048] By setting the positioning element 24 to cooperate with the soft coil 25, the sliding of the limiting block 18 causes the positioning element 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 easily adapt 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 element 24, thereby ensuring that the center of the breast is aligned with the center of the coil, ensuring that the entire breast tissue is within the imaging field of view, thus obtaining a clearer and more accurate image. It is not only simple and ingenious in structure, but also convenient and labor-saving in actual operation.

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

[0050] During use, the patient must remove all metal objects to avoid magnetic field interference. The patient should change into the examination gown provided by the hospital. The patient should lie prone on the examination bed 2, exposing the breasts so that both breasts hang naturally between the limiting blocks 18. The distance between the limiting blocks 18 can be adjusted by rotating the screw 20, so that the limiting blocks 18 are close to the breasts but do not compress them. The head is placed on the headrest 9, and both arms are extended upwards 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 pads 10 are on the inclined surface 7 to ensure patient comfort and reduce pressure. The S-shaped curved elastic structure at the bottom of the support plate 11, combined with the outward bending and widening of the bending part 12, makes the support plate 11 elastic. Under the action of elasticity, 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 reduced in height due to the pressure of the patient's own weight, the opposing lower weakening grooves 13 gradually approach each other and provide more deformation capacity to the support plate 11 through the staggered distribution, thereby adapting to patients with larger weights.

[0051] After the patient lies face down, hold the soft pad 17 and pull it upwards, then fix it 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 higher, which can acquire better images when breast cancer patients or other patients have axillary lymph node metastasis and swelling.

[0052] After the test, the Velcro on the soft pad 17 is loosened, and the elastic band 16 is retracted to the bottom of the support plate 11 using its own elasticity. The soft pad 17 is then positioned at the top of the perforation 15, providing soft support to the bend 12 on the support plate 11 to improve patient comfort. The spacing between the limiting blocks 18 can be adjusted by rotating the screw 20 to accommodate patients with different breast sizes. Since the bottom of the limiting blocks 18 is fixedly connected to the same connecting rope 23, and a positioning element 24 is fixedly connected to the center of the connecting rope 23, and the connecting rope 23 is a soft rope, the movement of the limiting blocks 18 allows the spacing between the limiting blocks 18 to be adjusted. As the area formed changes, the connecting rope 23 and the positioning element 24 also change synchronously. The positioning element 24 always corresponds to the central axis between the limiting block 18. Since the top of the soft coil 25 is fixedly connected to the limiting block 18 fixedly connected to the inner wall of the detection port 5, and the bottom of the soft coil 25 passes through the through hole 22 and is fixedly connected to the positioning element 24, the soft coil 25 is a conical spiral shape that is thicker at the top and thinner at the bottom. The central axis of the soft coil 25 will correspond to the center of the positioning element 24, thereby ensuring that the center of the breast is aligned with the center of the coil, ensuring that the entire breast tissue is within the imaging field of view, thereby obtaining a clearer and more accurate image.

[0053] During the scan, the patient must remain still to avoid respiratory movements or body swaying that could affect image quality. Correct positioning can reduce skin folds and motion artifacts, improving diagnostic accuracy. This device can be used not only by patients with thick abdominal fat, but also by adapting to the patient's weight during placement, thus providing better support and containment for the abdomen and improving user comfort. It can also accommodate patients with different breast sizes, ensuring alignment between the breast center and the coil center, and ensuring that the entire breast tissue is within the imaging field of view, thereby obtaining clearer and more accurate images.

Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, elements, and circuits are not described in detail.
