Description

Technical Field

[0001] The present invention belongs to the technical field of medical imaging, and in particular relates to a nuclear magnetic resonance auxiliary examination system. Background Art

[0002] As we all know, nuclear magnetic resonance imaging technology uses the principle of nuclear magnetic resonance (NMR). Based on the different attenuation of the released energy in different structural environments inside the material, the emitted electromagnetic waves are detected by applying an external gradient magnetic field to know the position and type of the atomic nuclei that make up the object, and based on this, a structural image of the object's interior can be drawn.

[0003] The medical applications of MRI (magnetic resonance imaging) mainly involve the detection and diagnosis of heart disease, cerebrovascular accidents and vascular diseases; the detection and diagnosis of diseases of the organs in the chest and abdomen; the diagnosis and evaluation, and tracking of tumor conditions and functional disorders. Considering that MRI is widely used in the diagnosis of sports-related injuries, it can present clear images of the soft tissues near and around bones, including ligaments and muscles. Therefore, it is a very sensitive examination for spinal and joint problems. Because MRI does not have the risk of radiation exposure, it is often used in the detection and diagnosis of reproductive system, breast, pelvic and bladder diseases.

[0004] For some lesions, basic MRI detection is not clear enough, so a radio frequency receiving coil is used to enhance the imaging effect. However, due to the different body shapes of the people being examined and the parts that need to be located and examined, a single coil cannot meet the usage requirements.

[0005] At the same time, the birdcage coil is extremely inconvenient for testing some injured patients and can easily cause secondary injuries.

[0006] Therefore, it is very important to design a nuclear magnetic resonance auxiliary examination system that can improve the magnetic enhancement of the inspected area, does not require the inspected person to be lifted, and can reduce secondary injuries to some injured patients. Summary of the invention

[0007] The present invention aims to overcome the problem in the prior art that the existing basic MRI detection cannot meet the requirements of multi-angle positioning detection and detection of different body positions, and the use of birdcage coils is extremely inconvenient for detecting some injured patients and easily causes secondary injuries. The present invention provides a nuclear magnetic resonance auxiliary inspection system that can improve the magnetic enhancement of the detected area, does not need to lift the detected person, and can reduce secondary injuries to some injured patients.

[0024] In order to more clearly illustrate the embodiments of the present invention, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those of ordinary skill in the art, other accompanying drawings and other implementation methods can be obtained based on these accompanying drawings without creative work.

[0025] like Figure 1 The present invention improves the examination bed of the MRI apparatus shown in the figure, and provides a MRI auxiliary examination system, which specifically includes: an examination bed 1, slide grooves 11 arranged on both sides of the examination bed and a moving structure arranged in the slide grooves; the slide grooves are located below the examination bed; the slide grooves located on both sides of the examination bed are symmetrical; a moving structure is arranged in each slide groove; a plurality of coil blocks 5 are arranged above the moving structure; and two adjacent coil blocks are detachably connected.

[0026] Further, such as Figure 2 As shown, each movable structure includes two sliders 7, a rotating roller 2 arranged in the slider, a handle 3 arranged in the middle of the rotating roller, and a flexible coil belt 6 wound around the two rotating rollers; each rotating roller is rotationally connected to the corresponding slider.

[0027] Furthermore, a telescopic rod 4 is provided on the handle; the top of the telescopic rod is movably connected to the bottom of the coil block.

[0028] Furthermore, a through hole is provided on the slider; the width of the through hole is greater than the width of the flexible coil belt; the flexible coil belt is released or tightened by the rotating roller through the through hole.

[0029] Another example Figure 2 , Figure 3 and Figure 5 As shown, the flexible coil belt is wound on a rotating roller, the rotating roller extends into the slider and is rotatably connected to the slider, the flexible coil belt and the rotating roller extend into the slider and are wound together, and the slider is restricted by the slide groove and can only slide along the slide groove. Therefore, when the rotating roller rotates, the slider will not move, and the flexible coil belt will be tightened or released.

[0030] The coil block located at the top also moves with the movement of the telescopic rod. When the distance between the two rotating rollers becomes farther, the coil block at the upper part will extend.

[0031] Further, such as Figure 1 As shown, a gear 10 is provided on the rotating roller; racks 8 are also provided on the edges of both sides of the examination bed; the gear on the rotating roller meshes with the rack on the same side. The gear is located at the junction of the rotating roller and the slider.

[0032] When the upper handle is moved upward, the slider will slide in the limit groove (slide groove). When the slider moves, the gear on the rotating roller will mesh with the rack of the examination bed, driving the rotating roller to rotate counterclockwise, so that the rotating roller releases the flexible coil belt, and when the lower handle is moved upward, the rotating roller will rotate counterclockwise to tighten the flexible coil belt.

[0033] Further, such as Figure 4 As shown, two adjacent coil blocks are connected by a ball joint 9. The ball joint can be rotated freely and can be unplugged and plugged in. Through the ball joint connection, each coil block can be disassembled and rotated separately, and the angle can be adjusted. The distance between the coil block and the patient can also be adjusted by adjusting the telescopic rod, so as to adapt to the application of large belly or head and other positions.

[0034] The working mode of the nuclear magnetic resonance auxiliary inspection system of the present invention is as follows:

[0035] First, rotate the coil block combination to open, let the patient lie on the examination bed, then rotate the coil block group, and the doctor moves the upper handle, for example, moves it upward, and moves the slider to the area that needs enhanced examination. At the same time, during the movement, the gear will engage with the rack, driving the rotating roller to rotate counterclockwise, releasing the flexible coil belt from the rotating roller, and then move the lower handle to the required position, so that the flexible coil belt is placed under the detected area, strengthening the magnetic field of the detected area and enhancing the imaging effect.

[0036] After completing the lower position adjustment, first adjust the telescopic rod, and then rotate and adjust the coil block through the ball connection to make the coil block fit the body shape of the patient being examined as much as possible, such as the face, abdomen, head and other curved parts. The magnetic field in the upper area is enhanced through the coil block group to strengthen the imaging effect.

[0037] The present invention adjusts the width of the flexible coil belt to adapt to different detection areas through a mobile structure arranged under the examination bed. During the adjustment process, the gear in the mobile structure meshes with the rack, and the flexible coil belt can be retracted and tightened to improve the magnetic enhancement of the detected area. There is no need to lift the person being detected, thereby reducing secondary injuries.

[0038] At the same time, a moving mechanism (telescopic rod and coil block) is provided on the top, which can adapt to different detection areas of the human body through movement adjustment, free plug-in and steering.

[0039] The above description is only a detailed description of the preferred embodiments and principles of the present invention. For ordinary technicians in this field, according to the ideas provided by the present invention, there will be changes in the specific implementation methods, and these changes should also be regarded as the protection scope of the present invention.
