Description

Technical Field

[0001] The utility model relates to a medical imaging system, in particular to a transportation device for a magnetic resonance system. Background Art

[0002] The magnetic resonance system includes a superconducting magnet. The superconducting magnet reaches the superconducting state in a low-temperature environment to maintain the required main magnetic field strength. Usually, relatively expensive helium is used as a refrigerant to provide a cooling environment for the superconducting magnet. The refrigerant may be lost when the temperature rises, so that the refrigerant needs to be replenished again, resulting in a large cost waste. This makes it necessary to cool the refrigerant during transportation to avoid the evaporation of the refrigerant in the heating environment even when the coil of the superconducting magnet is not powered on. Usually, a compressor (such as a helium compressor) is used to achieve the above cooling. During transportation, the superconducting magnet and the compressor are usually arranged in a container, and the compressor is cooled by an air-conditioning system arranged in the container to ensure the normal operation of the compressor.

[0041] Reference Figure 1 , shows a schematic diagram of an exemplary MR (Magnetic Resonance) system 100 according to some embodiments. Among them, the operator workstation 110 is used to control the operation of the MR system 100. The operator workstation 110 is coupled to and communicates with the computer system 120. The computer system 120 can be used to process and store the image data generated by the MR system, such as MR signals. The computer system 120 can be coupled to and communicate with the MR system controller 130.

[0042] The MR system controller 130 may include a sequence pulse generator 133 that communicates with the operator workstation 110. In some embodiments, at least a portion of the sequence pulse generator 133 may be integrated into the magnetic resonance component 140 of the MR system 100.

[0043] The magnetic resonance component 140 includes a superconducting magnet 143 having a magnet bore to form a cylindrical imaging volume 146 for accommodating a scan object 170 when the MR system is operating. The superconducting magnet has superconducting coils 144 that provide a static uniform longitudinal magnetic field B0 throughout the cylindrical imaging volume 146 during operation.

[0044] The magnetic resonance component 140 also includes a radio frequency coil assembly and a gradient coil assembly 142. The radio frequency coil assembly may include, for example, a body coil 148 and a surface coil 149, which can be used to transmit and / or receive radio frequency pulse signals. The gradient coil assembly 142 is used to receive gradient pulse signals.

[0045] The MR system controller 130 can receive commands from the operator workstation 110 to indicate the MR scan sequence to be executed during the MR scan. The sequence pulse generator 133 of the MR system controller 130 generates radiofrequency pulses and gradient pulses based on the indicated scan sequence.

[0046] The radiofrequency pulses transmitted by the sequence pulse generator 133 are processed and amplified via the circuit 161 and then provided to the body coil 148. The body coil 148 then provides a transverse magnetic field B1, which is substantially perpendicular to B0 throughout the cylindrical imaging volume 146. This transverse magnetic field B1 is used to excite the excited nuclei (or protons) in the scanned object's body to generate an MR signal.

[0047] The gradient pulses transmitted by the sequence pulse generator 133 are sent to the gradient driver 150, which includes G x 、G y and G z amplifiers, etc. Each of the G x 、G y and G z gradient amplifiers is used to excite the corresponding gradient coils in the gradient coil assembly 142 based on the gradient pulses to generate a gradient magnetic field superimposed on the static magnetic field and to generate a magnetic field gradient for spatially encoding the MR signal during the MR scan.

[0048] The RF body coil 148 and the RF surface coil 149 can be used to transmit radiofrequency pulses and / or receive the MR signals from the object during the magnetic resonance scan of the object. The MR signal can be sensed and received by the RF body coil 148 or the surface coil 149 and processed by the circuit 162 to form an image data array. The processor (not shown in the figure) in the MR system controller 130 is used to generate a reconstructed image based on the image data. In response to commands received from the operator workstation 110, these images can be transmitted to the computer system 120 for further processing and then transmitted to the operator workstation 110 for presentation on the display (not shown in the figure) of the operator workstation 110.

[0049] Figure 2 The structural schematic diagram of cooling the superconducting magnet of the magnetic resonance system using a compressor in some other embodiments is shown, in which the magnetic resonance component 210 and the compressor 224 are shown. The magnetic resonance component 210 can include Figure 1Part or all of the component 140 therein, for example, includes a superconducting magnet 213 and a superconducting coil 211. As described above, the superconducting coil 211 is used to generate a main magnetic field, and the superconducting coil 211 needs to be cooled to the superconducting state to maintain the required main magnetic field strength. For this purpose, the superconducting coil 211 is immersed in a cryostat 221, and the cryostat 221 is used to contain a cryogenic refrigerant. In addition to being immersed in the cryostat, the superconducting coil 211 can exchange heat with the cryogenic refrigerant in other ways to reach the required temperature. Generally, liquid helium can be used as the cryogenic refrigerant. Specifically, the cryostat 221 can surround the superconducting magnet 213 where the superconducting coil 211 is located. The cryostat 221 can be arranged in a thermal shield 222, and a vacuum shielding area can be provided between the thermal shield 222 and the cryostat 221. The thermal shield 222 and the vacuum shielding area isolate the cryogenic refrigerant from external heat sources, thereby avoiding the volatilization of the cryogenic refrigerant. The cryostat 221 is provided with a pressure relief valve 223 for releasing excessive pressure caused, for example, by the volatilization of the refrigerant. During the operation or transportation of the magnetic resonance system, the volatilization of the cryogenic refrigerant should be avoided. On the one hand, the volatilization of the refrigerant may cause the superconducting magnet to quench, and re-excitation will incur a large cost. On the other hand, the cryogenic refrigerant itself is relatively expensive, and volatilization will result in a large cost waste.

[0050] The compressor 224 is used to cool the refrigerant in the cryostat 221. Specifically, the compressor 224 provides cooling capacity to the cold head 226 of the magnetic resonance system, and the cold head then cools the refrigerant in the cryostat 221 by exchanging heat with the cryostat 221.

[0051] Generally, before leaving the factory, the magnetic resonance system needs to be filled with refrigerant in the cryostat 221 to avoid this complex operation at the installation site. Therefore, it is necessary to keep the refrigerant in the cryostat 221 at a low temperature during transportation. For this purpose, it is desirable to ensure that the compressor works normally to ensure the cooling effect of the refrigerant.

[0052] The compressor 224 needs to be refrigerated to work normally. Therefore, an air conditioner is usually installed in the transportation container to ensure the normal operation of the compressor 224, thereby avoiding the temperature of the refrigerant in the cryostat 221 from rising and volatilizing into the external environment.

[0053] Figure 3The figure shows a three-dimensional structural schematic diagram of a transportation device for a magnetic resonance system according to some embodiments of the present utility model. The transportation device includes an integrated box body 310, which is used to carry a compressor 320 and a cooling system 330. The cooling system 330 cools the compressor in the integrated box body 310, and the integrated box body 310 is spatially isolated from the components to be transported of the magnetic resonance system (such as a superconducting magnet), so that the integrated box body 310 and the components it carries can be adapted to different transportation means as standard components. For example, the entire integrated box body 310 can be placed in a vehicle container together with the superconducting magnet, or can be arranged on a transport truck through a fixing rack and located outside the superconducting magnet container, or can be placed entirely in a train carriage, or can be part of a sea transportation component and combined with a special sea transportation container. After the transportation is completed, the integrated box body 310 can be removed from the corresponding container or fixing rack. Thus, it has high flexibility, improves transportation efficiency, does not need to provide different transportation plans to adapt to different transportation conditions, can adapt to the cooling environmental conditions of the magnet container itself, and due to the consistent operation brought by the integrated box body, reduces transportation operation errors.

[0054] Specifically, the compressor 320 and the cooling system 330 are provided in the integrated box body 310. An example of the compressor 320 is the above-mentioned compressor 224. The magnetic resonance system to be transported may include the components of the magnetic resonance system in any of the above embodiments or their deformations.

[0055] Reference Figure 3 , the compressor 320 is connected to the cold head of the magnetic resonance system 301 via a refrigerant pipe 321. The refrigerant pipe 321, the magnetic resonance system 301 and its cold head are all arranged outside the integrated box body 310. One end of the refrigerant pipe 321 is communicated with the compressor 320 via an interface (not shown in the figure) provided on the integrated box body. Specifically, the gaseous refrigerant (such as helium) generated by the cold head due to heat exchange enters the compressor 320 via the refrigerant pipe 321. The compressor 320 compresses the gaseous refrigerant to form a liquid refrigerant. The liquid refrigerant carries cold and enters the cold head via the refrigerant pipe 321. In some embodiments, the integrated box body 310 has a smaller volume than the container carrying the magnetic resonance system 301 so as to be able to enter and exit from the container.

[0056] The cooling system 330 is also arranged in the integrated box body 310 and is used to exchange heat with the compressor 320 in the integrated box body 310 to cool the compressor 320. In this way, there is no need to cool the compressor 320 by means of external cooling equipment during transportation.

[0057] In some embodiments, the transportation device further includes a container for accommodating the magnetic resonance system 301 to be transported and the integrated box body 310, wherein the integrated box body 310 can be removed from the container. Figure 4 , Figure 5 respectively show different application scenarios of the magnetic resonance system transportation device according to the embodiments of the present invention. As Figure 4 shown, the container 410 is provided with an opening 411, and at least a part of the integrated box body 310 can be arranged in the container 410 via the opening 411. The integrated box body 310 is communicated with the outside of the container 410 via the opening. For example, the integrated box body 310 can enter the container as a whole via the opening 411 (in other embodiments, it can also enter via the door of the container 410), or part of its volume can be located in the container 410 via the opening 411, and at least one side surface of the integrated box body 310 can be communicated with the opening 411. In other words, the at least one side surface is exposed from the opening 411, so that the operator can monitor or operate the equipment on the integrated box body 310.

[0058] In one embodiment, the integrated box body 310 includes an outer side portion 311, and the outer side portion 311 is communicated with the outside of the container 410 via the opening 411, wherein the outer side portion 311 can have a shape and size matching the opening 411. In some embodiments, a flange 312 is provided at the edge portion of the outer side portion 311 for connecting the wall of the opening 411, and the flange 312 can be at least partially arranged around the outer side portion 311.

[0059] The above-mentioned container 410 and integrated box body 310 can be matched in sets for sea transportation. For example, the container 410 is placed on a ship, and the integrated box body 310 is placed in the container 410 and forms an integral whole in appearance with the container 410. For example, the outer side portion 311 of the integrated box body 310 and the wall where the opening 411 is located are substantially in the same plane, or form an integral pattern or shape.

[0060] The above-mentioned container 410 can also be provided with a door 412 for the operator to pass through, and the door 412 can be on the same side or different sides of the container 410 as the opening 411. In some embodiments, the door 412 is arranged between the area where the magnetic resonance system 301 is placed and the area where the integrated box body 310 is placed, so as to facilitate the operation of any one of them.

[0061] As Figure 5 shown, the integrated box body 310 can be arranged as an independent device in a closed container 510, and the closed container 510 does not need to be provided with an opening for communicating the integrated box body with the outside. Therefore, the container 510 can be any existing container, such as a vehicle-mounted container, a train carriage or other cold chain transportation boxes.

[0062] During transportation, when it is necessary to change the means of transportation, the integrated box can be disassembled and reloaded as a whole.

[0063] In some embodiments of the present invention, the integrated box 310 has a cross-section of a non-rectangular polygon, for example Figure 4 As shown, the cross-section of the integrated box 310 is an irregular pentagon, and the volume formed by one of the narrower sides and the other two adjacent sides is arranged in the container 410 (for example, inside the opening 411), and a wider side opposite to this narrower side communicates with the outside of the container 410 through the opening 411. Through such a design, it is convenient for the integrated box 310 to enter and exit the opening 411, and a space is formed in the part of the integrated box 310 close to the door 412, which is convenient for the operator to operate and maintain the integrated box 310 behind the door 412.

[0064] In addition, emergency handles ( Figure 4 not shown in the figure) 513 are respectively provided on the containers 410 and 510 for opening the doors on the containers in case of emergency.

[0065] In some embodiments, an operation window or an operation door is provided on the outer side portion 311 of the integrated box 310 to facilitate equipment monitoring and operation. For example, the operator can observe or operate at least a part of the water cooling system, at least a part of the control and communication system, and / or at least a part of the power supply module described below through the operation window or the operation door on the outer side portion 311, that is, at least a part of these systems can be presented to the operator through the outer side portion 311.

[0066] As Figure 4 , Figure 5 shown, a heat insulation layer 315 can be provided on the inner side of the integrated box 310 to isolate the heat exchange with the outside of the integrated box 310. And further, seals (not shown in the figure) are provided between adjacent panels forming the integrated box 310.

[0067] Referring to Figure 6 , a schematic structural diagram of the integrated box 310 according to some embodiments of the present invention is shown. Among them, the cooling system 330 provided in the integrated box 310 includes a water cooling system 610. By cooling the compressor 320 through the water cooling system 610 closer to the compressor 320, the refrigeration efficiency can be improved, and the temperature control can be more precise, so that the compressor works in a stable temperature environment.

[0068] In some embodiments, the water cooling system 610 includes a water flow circuit, and the water flow circuit exchanges heat with the compressor 320 to transfer cold to the compressor.

[0069] Continue to refer to Figure 6 In an embodiment of the present invention, the water cooling system 610 may include a first water cooling module 620 and a second water cooling module 630. The first water cooling module 620 and the second water cooling module 630 respectively exchange heat with the compressor 320 alternately. In this way, the reliability of the compressor refrigeration is ensured, the volatilization of the superconducting cooling gas caused by abnormal operation of the compressor is avoided, and the power consumption is reduced, so that the power module equipped on the traditional cold chain transportation equipment can meet the power requirements of magnetic resonance transportation. However, in some special cases, for example, when the compressor needs more cooling capacity, the first water cooling module 620 and the second water cooling module 630 can be controlled to be turned on simultaneously to transfer cooling capacity to the compressor at the same time.

[0070] Refer to Figure 7 which shows a schematic structural diagram of a first water cooling module 610 according to an example of the present invention, including a first cooling unit 710 and a first water cooling circuit 720. The first cooling unit 710 is used for circulating a coolant, such as a Freon fluid. The first cooling unit 710 includes an evaporator 711, a compressor 712, a condenser 713, and an expansion valve 714. The Freon fluid is compressed into a high-pressure gas by the compressor 712. The high-pressure gas flows to the condenser 713 for condensation. The condensed Freon liquid flows to the expansion valve 714 to be depressurized and cooled. The depressurized and cooled Freon fluid flows to the evaporator 711 and is evaporated into a gas in the evaporator 711. The evaporation process absorbs heat, and the gas generated by evaporation is circulated to the compressor 712 for compression, and so on in a cycle.

[0071] The first water cooling circuit 720 is used for circulating cooling water, and devices such as a water tank and a pump may be provided therein. The first water cooling circuit 720 exchanges heat with the evaporator 711 to absorb the cold generated during the evaporation process of the coolant. The cold water with this cold then exchanges heat with the compressor 320 to cool the compressor 320. The temperature of the cold water rises after exchanging heat with the compressor 320 and continues to circulate in the circuit, and exchanges heat with the evaporator 711 again, and so on in a cycle.

[0072] Temperature sensors 730 are respectively provided at the water inlet and outlet of the first cooling unit 710 for monitoring the water inlet temperature and outlet temperature of the cooling unit 710 and sending the detected temperatures to a control module, such as the central controller 660 to be described below. The central controller 660 then judges the working state of the compressor 320 according to the received temperature information and performs corresponding operations on the compressor. In addition, pressure sensors 740 may also be provided at the water inlet and outlet of the compressor 320 to detect the air pressure. The central controller 660 can judge the working state of the compressor 320 by combining this temperature information and air pressure information. These will be described in detail below in conjunction with Figure 11 which will be described in detail.

[0073] Only one example of the first water cooling module 610 is shown above. The first water cooling module 610 may have other water cooling principles or structures. The second water cooling module 630 may have the same structure as the first water cooling module 620, so as to have a consistent refrigeration method and refrigeration effect on the compressor 320. Specifically, the second water cooling module 630 may include a second cooling unit 820 and a second water cooling circuit 830 (as Figure 8 shown), or the second water cooling module 630 may include a second cooling unit 820 and the first water cooling circuit 720, that is, share the water cooling circuit with the first water cooling module 610 to save space and cost.

[0074] Continuing to refer to Figure 6 , the water cooling system 610 further includes a first control module 640 and a second control module 650, which are respectively used to communicate with the first water cooling module 620 and the second water cooling module 630 to control the working states of the first water cooling module 620 and the second water cooling module 630. Specifically, the first control module 640 and the second control module 650 are used to communicate with the central controller 660 to control the corresponding first water cooling module 620 and second water cooling module 630 based on the control instructions of the central controller 660. For example, the central controller 660 may send a start instruction to the first water cooling module 620 or the second water cooling module 630 according to the set working time period to instruct the corresponding water cooling module to enter the working state. For example, the central controller 660 may turn off the currently working water cooling module every 12 hours and at the same time start the currently resting water cooling module to achieve the alternating work of the water cooling modules. The central controller 660 may also adjust the working duration of the first water cooling module 620 and the second water cooling module 630 working alone or simultaneously according to various feedback information. For example, even if the currently working first water cooling module 620 has not reached the preset working duration, when the central controller 660 monitors that the first water cooling module 620 is abnormal according to the feedback information, it may be replaced by the second water cooling module 630 to work. In some embodiments, the first control module 640 and the second control module 650 may be programmable logic controllers (PLCs), and the central controller 660 may be any one of a computer system, an embedded system, an industrial control system, etc.

[0075] Refer to Figure 8, a schematic structural diagram of an integrated box body 310 according to some other embodiments of the present utility model is shown. Among them, an air-cooling module 810 is further provided in the integrated box body 310. The air-cooling module 810 exchanges heat with the water-cooling system 610 and cools the cold head of the magnetic resonance system. Specifically, the air-cooling module 810 may include a fan, which absorbs air from the internal space of the integrated box body 310 or from the external environment of the integrated box body 310 via the internal space. The air is cooled after exchanging heat with the water-cooling system 610, and the cooled air is then transported to the cold head to refrigerate the cold head. By air-cooling the cold head, the power requirement of the compressor 320 is reduced, and further the power requirement for refrigerating the compressor 320 is reduced.

[0076] Similar to refrigerating the compressor 320, the first water-cooling module 620 and the second water-cooling module 630 in the water-cooling system 610 can respectively and alternately exchange heat with the air-cooling module 810. For example, the first water-cooling module 620 may include a third water-cooling circuit 840, and the second water-cooling module 630 may include a fourth water-cooling circuit 850. The third and fourth water-cooling circuits may share the same circuit. And, similar to the heat exchange principle of the above-mentioned first water-cooling circuit 720 and second water-cooling circuit 830, the water with cold quantity in the third water-cooling circuit 840 and the fourth water-cooling circuit 850 is used to exchange heat with the air-cooling module 810, so that the air-cooling module 810 generates cold air (cooling air).

[0077] In some embodiments, when any one of the first water-cooling module 620 and the second water-cooling module 630 works, it can simultaneously provide cold quantity for the compressor 320 and the air-cooling module 810, or the heat exchange circuit of the air-cooling module (such as the third water-cooling circuit 840 or the fourth water-cooling circuit 850) can be closed to only provide cold quantity for the compressor 320.

[0078] The air-cooling module 810 transports cooling air to the cold head via an air duct 860 extending outside the integrated box body 310. Specifically, a connection port 870 is provided on the side wall of the integrated box body 310. One end of the air duct 860 can communicate with the air outlet of the air-cooling module 810 via the connection port 870. The air duct 860 is arranged outside the integrated box body 310, and the other end thereof can extend to the cold head of the magnetic resonance system.

[0079] Furthermore, the air-cooling module 810 also exchanges heat with the water-cooling system 610 as described above to output cooling air to the compressor in the integrated box body 310, which also reduces the power requirement of the water-cooling unit for refrigerating the compressor.

[0080] Reference Figure 9, which shows a schematic structural diagram of a transport device for a magnetic resonance system according to other embodiments of the present invention. It further includes a control and communication system 910, which includes the above-mentioned central controller 660. As described above, the central controller 660 (for example, directly or respectively through the first control module 640 and the second control module 650) is communicatively coupled to the above-mentioned first water cooling module 620 and second water cooling module 630 to control the first water cooling module 620 and the second water cooling module 630 to alternately exchange heat with the compressor 320.

[0081] The control and communication system 910 may further include at least one of a magnet monitoring module 911, a human-machine interaction module 912, and a remote communication module 913.

[0082] The magnet monitoring module 911 is configured to receive main magnet parameters from the magnetic resonance system and send the received main magnet parameters to the central controller 660. The central controller 660 can then perform corresponding operations according to the current state of the main magnet (superconducting magnet). For example, when the main magnet parameters are abnormal, the central processor can send instructions to adjust the refrigeration state of the compressor, report information via the remote communication module 913, control the restart of the compressor 320, etc.

[0083] The human-machine interaction module 912 is controlled by the central controller to display interaction information. For example, it can display feedback data from different monitoring modules or sensors for the operator to observe, and the operator can also send operation instructions to the central controller 660 via the human-machine interaction module 912.

[0084] The remote communication module 913 is used to provide a wireless connection between the central controller 660 and a remote device. The remote device can provide a remote control platform, which interacts with the central controller 660 via any one of a gateway, a router, a wireless network, a network cloud, and a satellite network. For example, it can obtain feedback data sent via the central controller 660 or remotely send operation instructions to the central controller 660.

[0085] Reference Figure 10 , which shows a schematic structural diagram of an integrated box 310 according to other embodiments of the present invention. It further includes a power supply module 1010, which is configured to receive an external power supply and distribute power to at least one of the compressor 320, the water cooling system 610, the air cooling module 810, and the control and communication system 910. Specifically, a power supply adapter interface (not shown in the figure) is provided on the side wall of the integrated box 310 for connecting to an external power supply, and the external power supply can be a power supply equipped on a transportation vehicle. The power supply module 1010 may include a power supply adapter unit for adjusting the power, frequency, phase sequence, etc. of the input power of the external power supply to adapt to the corresponding requirements of the compressor 320.

[0086] The above control and communication system 910 may further include a power detection module 1020, which is configured to detect the power of the power supply module 1010 and upload the power detection result to the central controller 660. The central controller 660 can then perform corresponding controls based on the power output signal of the power supply module 1010, such as adjusting power distribution, or controlling the startup and shutdown of the above-mentioned modules or systems that receive power distribution.

[0087] In an embodiment of the present invention, the compressor 320, the water cooling system 610, the air cooling module 810, the control and communication system 910, and the power supply module 1010 are respectively arranged in multiple divided spaces of the integrated box body 310. These spaces can be divided, for example, by distance or by setting partition boards. These spaces can be divided in the horizontal or vertical direction to have an optimized space distribution. Moreover, a plurality of operation windows or operation doors can be opened on the side plates of the integrated box body 310 to respectively communicate with these divided spaces, so as to facilitate the operation of the systems or modules therein.

[0088] As Figure 10 shown, an embodiment of the present invention may further include a shock damping device 1050, which is arranged in the integrated box body 310 to carry the components to be shock-damped. The shock damping device 1050 is arranged at the bottom of the compressor 320 to shock-damp the compressor 320 and protect the compressor from external forces. Figure 11 、 Figure 12 、respectively show a perspective structural view and a sectional view of the shock damping device 1050 according to an embodiment of the present invention. Among them,

[0089] the shock damping device 1050 includes a bottom support 1110 and a damping part 1120. The bottom support 1110 can be fixed on the ground or the support surface of the box body. The damping part 1120 includes an upper part 1130 and a lower part 1140. The upper part can be used to carry the compressor 320. The lower part 1130 forms a "U" shape structure. The "U" shape structure includes a surface 1141 that cooperates with the upper surface 1111 of the bottom support 1110 and two lateral extension parts 1142 that are lower than the surface 1141. The two lateral extension parts 1142 are respectively suspended on opposite sides of the bottom support 1110. A space 1150 is formed between the upper part 1130 and the lower part 1140 of the damping part 1120. Moreover, wire rope dampers 1160 are respectively installed between the upper part 1130 of the damping part and the two lateral extension parts 1142. Therefore, the vertically acting external force is buffered by the suspended damping part, the space 1150 between the upper and lower parts of the damping part, and the wire rope dampers arranged in the space.

[0090] Further, a damping space 1170 is formed horizontally between each wire rope damper 1160 and the lower part 1140 of the damping part 1120 to buffer the external force in the horizontal direction. In this way, when the compressor 320 swings in any direction under the action of the external force generated during transportation, the above shock-absorbing and damping device 1010 gradually converges the swing amplitude from different directions, thereby playing a better role in buffering, damping, and shock absorption to ensure the stability and reliability of the compressor operation.

[0091] An embodiment of the present invention further provides a magnetic resonance transportation method, which uses a magnetic resonance transportation device as shown in Figure 6 to transport a magnetic resonance system. Figure 13 shows a flowchart of the magnetic resonance transportation method according to some embodiments of the present invention, which includes at least one of steps 1310 and 1320: In step 1310, the first water cooling module 620 and the second water cooling module 630 are switched regularly. Specifically, the central controller 660 can switch the first water cooling module 620 and the second water cooling module 630 regularly based on a preset first period. For example, when the first period arrives, an opening signal can be sent to one of the water cooling modules (which is in a non-working state before the arrival of the second period), and a closing signal can be sent to the other water cooling module (which is in a working state before the arrival of the second period). In one example, the first period is 12 hours. In step 1320, the compressor 320 is reset regularly. For example, the central controller 660 can reset the compressor 320 regularly based on a preset second period. This reset can be performed by re-powering, which enables the compressor to regularly clear the saved error information and ignore the abnormal protection mechanism of the compressor, so that it can work normally to the maximum extent to protect the magnet from damage. The second period can be set according to the logistics arrival time and the liquid helium loss during reset. In an example of the present invention, the second period can be set to 12 hours or 24 hours.

[0092] Figure 14 shows a flowchart of the magnetic resonance transportation method according to other embodiments of the present invention, where the structures of the first water cooling module and the second water cooling module are as shown in Figure 7 Specifically, the first water cooling module 620 includes a first cooling unit 710 and a first water cooling circuit 720 that exchanges heat with the first cooling unit 710. The second water cooling module 630 includes a second cooling unit 820 and a second water cooling circuit 830 that exchanges heat with the second cooling unit 820. The method includes the following steps:

[0093] At step 1420, at least one of a first temperature difference, a second temperature difference, and a pressure difference is obtained in real time (dynamically), where the first temperature difference is the temperature difference between the water outlet temperature and the water inlet temperature of the first cooling unit or the second cooling unit currently in the working state, the second temperature difference is the temperature difference between the water inlet temperature and the water outlet temperature of the compressor 320, and the pressure difference is the pressure difference between the inlet air pressure and the outlet water pressure of the compressor 320.

[0094] For example, the central controller 660 can obtain temperature and pressure data from the corresponding temperature sensors or pressure sensors in real time and calculate the corresponding temperature differences and pressures.

[0095] At step 1430, a first determination is made, where it is determined whether at least one of the first temperature difference, the second temperature difference, and the pressure difference is not within the normal range; if so, step 1440 is executed, that is, a restart instruction is sent to the compressor 320; if not, return to step 1420.

[0096] In step 1450, a second determination is made, where it is determined whether the number of times of restarting the compressor within a preset time period has reached N; if so, the process ends and the first determination is stopped; if not, return to step 1430 to execute the first determination. Where N is greater than 1, and the preset time period can be, for example, 1 hour. By restarting the compressor 320 multiple times within a short time, ensure that it works as normally as possible, protect the magnet from damage, and at the same time limit the number of restarts within this time period to avoid too many restarts.

[0097] Normally, the compressor does not report its own abnormal state, making it difficult to detect compressor failures or abnormalities during transportation. In this way, compressor abnormalities can be detected in a timely manner and effective response operations can be carried out. By restarting or resetting the protection state of the compressor, the liquid helium in the magnet can be protected to a large extent, or the magnet can be protected from damage.

[0098] Figure 15 The flowchart of the transportation method of the magnetic resonance system according to some other embodiments of the present invention is shown, including the following steps.

[0099] At step 1510, device operation data is sent to the remote control platform via the remote communication module 913. At step 1520, the magnetic resonance system transportation device of the embodiment of the present invention is operated in response to an operation instruction from the remote control platform. For example, the remote control platform can display the models of the first water cooling module 620 and the second water cooling module 630 and display the parameter values of each component in the module in real time in the models. When any parameter value is abnormal, the operator can input the corresponding operation instruction on the remote control platform for remote maintenance intervention, or communicate with the transportation engineer in a timely manner.

[0100] The embodiments of the present utility model do not limit the order of the above steps. According to the specific on-site conditions, each step can be executed in the order of arrival by cycle or time, or a certain step can be immediately started based on a temporary event. Moreover, each step can be independently executed, that is, the execution of each step is not affected by the results or events in other steps.
