Description

Technical Field

[0001] The present invention relates to the technical field of magnetic resonance equipment, and in particular to a separate portable mobile magnetic resonance system. Background Art

[0002] Currently, all MRI systems on the market are fixed installation types and need to be installed in MRI shielded rooms in fixed locations. Therefore, patients who need to undergo MRI examinations need to be sent to the MRI examination room for scanning.

[0003] However, for some special patients, it is not convenient to move long distances due to treatment needs, especially patients in ICU wards and some emergency patients. Some patients in specialist clinics also need to queue up in fixed MRI examination rooms when they need MRI examinations, which increases the patient's consultation time. The hospital's current solution to the above problems is to use mobile CT for examinations, but CT scans will have strong radiation, which will cause radiation to patients and surrounding medical staff, and it is not suitable for frequent scanning of patients.

[0004] Therefore, there is an urgent need for a portable and movable magnetic resonance system to meet the above needs. Summary of the invention

[0005] In view of this, the present invention proposes a separate portable mobile magnetic resonance system, aiming to solve the existing problems.

[0026] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to be able to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] See also Figure 1-6 , which is a separate portable mobile magnetic resonance system provided by an embodiment of the present invention, including a main cabinet 1 and a control cabinet 6, and the main cabinet 1 and the control cabinet 6 are connected by a cable.

[0028] The main cabinet 1 includes a mobile chassis 7, a magnetic resonance scanning host and a housing 5. The mobile chassis 7 includes a platform 101 and a walking wheel mechanism 105 arranged at the bottom of the platform; the magnetic resonance scanning host is fixed on the platform 101 and is located in the housing 5; the housing 5 is symmetrically provided with through holes 501, which are arranged at positions corresponding to the scanning area of ​​the magnetic resonance scanning host, so that patients can pass through and enter the scanning. In addition, the housing 5 is also provided with an observation window 502 for easy observation.

[0029] The control cabinet 6 includes a cabinet 601, and a plurality of shelves 602 are arranged in the cabinet 601. The shelves 602 are respectively provided with various control components, including a spectrometer, a radio frequency device, a gradient device, a temperature control device and a system power supply, etc.; a plurality of rollers 603 are arranged at the bottom of the cabinet for easy movement. Among them, the temperature control device is used to heat the magnet 103 to keep the temperature of the magnet 103 constant and keep the magnetic field strength unchanged. The spectrometer is used for transmitting, receiving and processing the scanning sequence signal of the magnetic resonance system, and is a key component of magnetic resonance imaging. The gradient device is used for transmitting the gradient signal when the magnetic resonance system is scanning, so that the system generates a gradient magnetic field. The system power supply is used to power the entire magnetic resonance imaging system.

[0030] Further, if Figure 2-4 As shown, the magnetic resonance scanning host includes a magnet 103 and a shielding device 102; the magnet 103 is installed in the shielding device 102; an opening is provided on the shielding device 102, and the opening corresponds to the through hole 501 on the main cabinet shell, thereby ensuring that the patient can enter for scanning imaging.

[0031] The shielding device 102 is arranged outside the magnet 103, and can shield the external electromagnetic signal from interfering with the imaging of the magnet 103. At the same time, other imaging working parts are installed in the shielding device 102, which plays a supporting and installing role for the magnetic resonance imaging system. The shielding device is usually made of a metal material with good conductivity (such as a galvanized steel plate, a stainless steel plate or a copper plate, etc.), and its structure can be a thin shell box structure.

[0032] Among them, the magnet 103 is a double-sided column frame structure with symmetrical columns on both sides. The magnet yoke of this structure has high magnetic permeability, so that under the same magnetic field, the magnet structure can be more compact and light in weight, which can meet the requirements of portable and mobile use of the magnetic resonance system. Because the magnet yoke of this structure has high magnetic permeability, there are very few magnetic lines of force passing through the outside of the magnet 103, and there will be no magnetic field interference to the normal operation of other equipment. At the same time, the symmetrically arranged double-column magnet structure is stable and rigid, which can ensure that no deformation will occur during the lifting process of the magnet, affecting the magnet performance.

[0033] Furthermore, in order to facilitate adjustment and adapt to beds of different heights, the magnetic resonance scanning host also includes a lifting device, which is installed on the outside of the shielding device 102, fixed on the platform of the mobile chassis 101, and fixedly connected to the magnet. The lifting device includes a lifting rod 104, the bottom of which is fixed on the platform 101 of the mobile chassis, and a lifting bracket 111 is provided at its end, and the lifting bracket 111 is fixedly connected to the column of the magnet.

[0034] In order to better connect with the magnet 103 and make the system lifting more stable, the lifting bracket 111 is preferably a "├"-shaped bracket, the vertical part of which is fixedly connected to the column of the magnet, and the horizontal part is fixed to the end of the lifting rod 104. In order to play a better supporting role, a number of supporting ribs are also provided between the vertical part and the horizontal part. There are 4 lifting rods 104, which are symmetrically arranged around the shielding device 102.

[0035] In this way, the magnetic resonance imaging system can be flexibly moved by the mobile chassis 7, and the lifting and lowering movement of the magnetic resonance imaging system can be achieved by the synchronous lifting and lowering movement of the symmetrically arranged lifting devices, which is convenient for adjustment.

[0036] Furthermore, the main Figure 5-6 As shown, the outer sides of the body cabinet 1 and the control cabinet 6 are both provided with a hooking device 8, which can be hooked together. This can make the portable mobile magnetic resonance system more adaptable to space. In a relatively narrow ward, the magnetic resonance body cabinet 1 and the control cabinet 6 can be separated for use, and the magnetic resonance body cabinet 1 only needs to be moved to the side of the bed 3 to perform a scan examination on the patient 2. After the scan examination is completed, the hooking device 8 of the magnetic resonance body cabinet 1 is connected to the hooking device 8 of the control cabinet 6, so that the magnetic resonance body 1 and the control cabinet 6 are hooked together, and the control cabinet 6 is dragged to move while the magnetic resonance body 1 moves.

[0037] Furthermore, in order to ensure electrical safety, a cable drag chain 9 is connected between the main cabinet 1 and the control cabinet 6 , and the cables are arranged in the cable drag chain 9 .

[0038] Furthermore, the detachable portable mobile magnetic resonance system of the embodiment of the present invention further includes a bed 3 , which includes an extension plate 4 , and the extension plate 4 can extend into the through hole on the outer shell of the main cabinet 1 and enter the scanning area of ​​the scanning host 5 .

[0039] When the detachable portable mobile magnetic resonance system of the present invention is used, the main cabinet 1 is first moved to the bed 3 of the patient 2 who needs to be examined through its mobile chassis 7. Then the patient 2 is moved upward on the bed 3 so that the part that needs to be examined protrudes a certain distance from the bed 3, and the extension plate 4 is inserted under the body of the patient 2 to support the part of the body of the patient 2 protruding from the bed. After adjusting the patient's examination position, the control device of the lifting device in the control cabinet 6 is adjusted, and the scanning space height of the magnetic resonance scanning host is adjusted by the up and down movement of the lifting column 104 to adapt to the height of the bed 3 of different patients, so that the part that needs to be scanned by the patient is located in the middle of the scanning space of the equipment. Then the bed 3 is moved forward so that the patient 2 enters the scanning space of the magnet 103 through the through hole 502 together with the extension plate, and the part to be examined is located in the middle of the scanning space. Then the magnetic resonance scanning host is operated to perform nuclear magnetic imaging scanning on the patient, and after the scanning is completed, the lesion image of the patient 2 is directly read for on-site diagnosis, which is convenient and quick.

[0040] The separate portable mobile magnetic resonance system provided by the embodiment of the present invention has the following beneficial effects:

[0041] 1. By setting up a main cabinet and a control cabinet, the MRI scanner body and the control system are separated and placed in the main cabinet and the control cabinet respectively. This not only reduces the weight of the MRI body, facilitates movement, and has better spatial adaptability; it also reduces the impact of the working noise of each control component on the patient during MRI scanning.

[0042] 2. A shielding device is installed on the outside of the magnet to shield external signal interference during magnetic resonance scanning.

[0043] 3. The main part of the magnetic resonance imaging system is connected to the lifting device, which is installed on the mobile chassis and can adjust the height of the magnetic resonance main structure to adapt to different bed scanning heights.

[0044] 4. The magnet adopts a frame structure, which can also increase the magnetic conductivity, not only improve the magnetic field strength, but also increase the stability of the magnet structure, thereby ensuring that the magnet will not be deformed when it is lifted or lowered, improving the magnet performance and reducing the magnet weight.

[0045] The portable mobile magnetic resonance system of the present invention has a compact structure, is light in weight and can be portable. It can be moved to the side of a patient's bed to perform a scan on the patient, thereby minimizing the movement of the patient. It is particularly suitable for examining patients who have just completed surgery and are not suitable for movement, and no other unnecessary injuries will be caused by the movement of the patient.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
