Description

Technical Field

[0001] The utility model relates to the technical field of magnetic resonance imaging, and more particularly to a magnetic resonance imaging device for surgical operations. Background Art

[0002] Magnetic Resonance Imaging (MRI) has no radioactive damage and no biological damage compared with the existing Computed Tomography (CT). It can directly produce tomographic images of cross-section, sagittal plane, coronal plane and various inclined planes, is not interfered by bone images, and has good recognition of small lesions in the posterior cranial fossa bottom, brainstem and other places. Therefore, it is becoming more and more widely used in the existing disease detection and diagnosis.

[0003] Magnetic resonance imaging technology has also been more and more widely applied to surgeries, and real-time imaging is performed on surgical patients during surgeries, so as to judge the specific situation of the surgery on the lesion position during the surgery, ensure that the surgery on the lesion position is more accurate, and avoid misoperations on patients during surgeries. However, since magnetic resonance imaging technology needs to operate in a special environment, for example, imaging is performed in a radiofrequency shielding environment, and a high-intensity magnetic field is generated by superconductivity on the magnetic resonance imaging device, the high magnetic field needs to reduce the influence of magnetic materials in the external environment during use, so as to reduce interference during the imaging process.

[0004] In the related art, by transforming the overall environment of the operating room, the overall operating room is transformed into a radiofrequency shielding environment, and the magnet of the magnetic resonance imaging device is transformed by moving the magnet in the magnetic resonance imaging device to realize the detection of the surgical position of the patient during the surgery. However, since the magnet of the magnetic resonance imaging device is precise, complex, expensive, and has a large mass, when using the related technology for transformation, the equipment transformation cost is high, the transformation period is long, and the magnet may also have problems and cannot be used normally, so it cannot be promoted and used. If the patient is moved to the magnet of the magnetic resonance imaging device during the surgery, the patient undergoing the surgery needs to be transferred from the operating table to the diagnostic bed of the magnetic resonance imaging device. During the transfer of the surgical patient, accidents are likely to occur, increasing the risk during the surgery. And when the surgical patient is moved to the magnet, on the one hand, multiple medical staff are required to participate in the patient transfer process at the same time, increasing the complexity of the surgical process. On the other hand, a specific alignment device is required to align the position to be detected of the patient with a specific area of the magnet. When the surgical position is different, the alignment difficulty is high and accurate alignment cannot be achieved. Summary of the Invention

[0040] To solve the problems in the related art that the cost of magnetic resonance imaging equipment is high, the installation time is long, it is impossible to perform real-time detection on a surgical patient during surgery, and it is impossible to align the area to be detected of the surgical patient, the present utility model provides a magnetic resonance imaging equipment for surgical operations. The equipment includes but is not limited to: a magnet device fixedly arranged in a first environment with radio frequency shielding, used to generate detection signals, the magnet device is configured with a cylindrical through hole for positioning the target detection position of the surgical patient within the coverage range of the detection signals; an imaging control system communicatively connected to the magnet device for receiving the detection signals to generate detection images; a movable operating table provided with a driving device for moving the movable operating table and a power supply device for supplying power to at least the driving device; a precise tracking device including a route recognition device arranged on the movable operating table and a track route extending from a second environment to the first environment, the second environment being different from the first environment; the precise tracking device is configured to identify the track route through the route recognition device and control the driving device to move the movable operating table between the first environment and the second environment, wherein when the movable operating table moves from the second environment to the first environment, the target detection position of the surgical patient on the movable operating table is within the coverage range of the detection signals.

[0041] According to an embodiment of the present utility model, by fixedly arranging the magnet device in the first environment with radio frequency shielding, the interference of external factors on the magnet device can be reduced. By providing a movable operating table, the surgical patient during surgery can be smoothly and accurately moved from the operating room with a surgical environment to the set position of the magnetic resonance imaging equipment with a radio frequency shielding environment, avoiding accidents during the movement of the patient. By providing a precise tracking device, precise navigation of the movable operating table can be achieved, and the position to be detected of the surgical patient can be accurately moved to a specific area of the magnetic resonance imaging equipment for alignment, realizing the detection of the surgical position of the surgical patient during surgery to generate detection images and improving the imaging accuracy rate.

[0042] The following combines Figures 1 to 6C to elaborate in detail on the magnetic resonance imaging equipment for surgical operations according to the embodiments of the present utility model.

[0043] Figure 1Schematically shows a structural diagram of a movable operating table of a magnetic resonance imaging device for surgical operations according to an embodiment of the present invention in a second environment. Figure 2 Schematically shows a structural diagram of a movable operating table of a magnetic resonance imaging device for surgical operations according to an embodiment of the present invention in a first environment.

[0044] As Figures 1 to 2 shown, the magnetic resonance imaging device for surgical operations of the present invention can be installed in two different areas. For example, a first environment A with radio frequency shielding and a second environment B without radio frequency shielding. The first environment A can be, for example, a diagnostic room, and the second environment B can be, for example, an operating room. Radio frequency shielding materials are installed in the diagnostic room to shield radio frequency signals from the external environment in the first environment A and reduce interference from external signals received by the magnetic resonance imaging device. There are no radio frequency shielding materials in the operating room. In the second environment B, it is necessary to ensure the safety of the patient during the operation. For example, the second environment B has a set cleanliness level, such as a sterile room, to prevent the patient from being affected by the external environment during the operation.

[0045] Exemplarily, between the first environment A and the second environment B, an isolation door C can be provided, for example. The isolation door C separates the first environment A and the second environment B. When the isolation door C is open, it is convenient for the movable operating table to move between the first environment A and the second environment B. When the isolation door is closed, in the case where the first environment A is under radio frequency shielding, during the magnetic resonance detection process, interference caused by external radio frequency can be effectively prevented, improving the detection accuracy.

[0046] In an embodiment of the present invention, as Figure 1 and Figure 2 shown, the magnetic resonance imaging device 100 for surgical operations includes a magnet device 10, an imaging control system 20, a movable operating table 30, and a precise tracking device 40.

[0047] The magnet device 10 is fixedly arranged in the first environment A with radio frequency shielding and is used to generate detection signals. The magnet device 10 is configured with a cylindrical through hole 101, and this cylindrical through hole 101 is used to make the target detection position of the surgical patient within the coverage range of the detection signals. The magnet device generates detection signals, for example, by collecting magnetic resonance signals to generate detection signals, and these detection signals can be analyzed and processed to generate detection images.

[0048] The imaging control system 20 is communicatively connected to the magnet device 10, and is configured to receive detection signals and process the detection signals to generate detection images. The imaging control system 20 includes, for example, hardware systems such as a computer, a processor, or a server, and can be used to perform functions such as inputting surgical patient information, defining scanning parameters, executing scanning sequences, controlling data acquisition, reconstruction processing, displaying, and storing the generated detection results.

[0049] The movable operating table 30 is provided with a driving device for moving the movable operating table, and a power supply device for supplying power to at least the driving device. The movable operating table 30 is further provided with a vital sign detection device for detecting or maintaining the vital signs of the surgical patient. The vital sign detection device includes, for example, devices such as an anesthesia machine, a ventilator, a monitor, an infusion pump, etc., and is used to detect the vital signs of the surgical patient during the operation, or to assist the doctor in performing the operation. In an embodiment of the present invention, the vital sign detection device is detachably connected to the movable operating table and can be synchronously moved with the movable operating table 30 to the position of the first environment A where the magnet device 10 is located, facilitating real-time detection of the patient during the operation. At the same time, it is not necessary to move the surgical patient, reducing the accidental situations caused by the movement of the patient during the operation. The driving device is used to drive the movable operating table 30 to move between the first environment A and the second environment B, so as to complete the movement of the surgical patient from the surgical position to the position where the magnet device 10 is located, detect the target detection position of the surgical patient undergoing the operation, thereby accurately determining the surgical progress of the surgical patient and improving the accuracy of the doctor during the operation. The power supply device supplies power to at least the driving device, enabling the driving device to drive the movable operating table to move. The power supply device can be, for example, a rechargeable battery that can be recycled, or a storage battery, etc. The power supply device can also be, for example, a plug device with a retractable cable pair for electrically connecting to the circuit in the first environment A or the second environment B. In other alternative embodiments, the power supply device can also supply power to other devices or equipment on the movable operating table.

[0050] The precise tracking device 40 includes a route recognition device provided on the movable operating table 30 and a trajectory route extending from the second environment B to the first environment A, where the second environment B is different from the first environment A. The precise tracking device 40 is used to control the specific route and moving speed of the driving device when moving between the first environment A and the second environment B, thereby realizing the movement control of the movable operating table.

[0051] In an embodiment of the present utility model, by providing a precise tracking device and a track route extending from the second environment B to the first environment A, a trackless design of the mobile operating table is achieved, that is, no tracks for the mobile operating table to move need to be provided in the first environment A and the second environment B. On the one hand, the trackless design can meet the requirements of a sterile and pollution-free source in the second environment B. On the other hand, the trackless design can effectively reduce the manufacturing cost of the magnetic resonance imaging device used in surgical operations.

[0052] Figure 3 Schematically shows a structural diagram of a magnet device of a magnetic resonance imaging device for surgical operations according to an embodiment of the present utility model. Figure 4A Schematically shows a structural diagram of a mobile operating table of a magnetic resonance imaging device for surgical operations according to an embodiment of the present utility model. Figure 4B Schematically shows a structural diagram of a mobile operating table of a magnetic resonance imaging device for surgical operations according to another embodiment of the present utility model.

[0053] As Figure 3 shown, the magnet device 10 is provided with a cylindrical through hole 101, and the cylindrical through hole 101 is adapted to allow a surgical patient or a diagnostic patient to pass through, so that the target detection position of the surgical patient or the diagnostic patient is located within the cylindrical through hole 101 and within the coverage of the detection signal generated by the magnet device 10.

[0054] In an embodiment of the present utility model, the magnet device 10 has a first end M and a second end N which are oppositely arranged, and the first end M and the second end N are oppositely arranged along the axial direction of the cylindrical through hole 101. The surgical patient on the mobile operating table 30 is adapted to enter the cylindrical through hole 101 of the magnet device 10 from the first end M of the magnet device, so that the target detection position of the surgical patient is within the coverage of the detection signal.

[0055] A magnet made of a superconducting material is provided inside the magnet device 10. The superconducting material includes magnesium diboride, niobium tin, niobium titanium, etc. The superconducting material has superconducting properties at a temperature of 40K (Kelvin) or below 40K. Therefore, the superconducting material can be cooled by a cooling system other than liquid nitrogen to make it have superconducting properties at 40K or below.

[0056] The magnet device 10 is fixedly arranged in the first environment A with radio frequency shielding. For example, the magnet device 10 is fixedly arranged in a diagnostic room. It can reduce the interference received by the magnet device 10 during the detection process, and at the same time be isolated from the operating room, and will not cause electromagnetic interference to other devices in the operating room (such as a vital sign detection device, etc.).

[0057] The imaging control system 20 can be located in a third environment, which is different from the first environment A and the second environment B, reducing the interference between the magnet device and the physical sign detection device. The imaging control system 20 is communicatively connected to the magnet device 10, receives the detection signal of the magnet device, and processes the detection signal to generate a detection image, so that the doctor can accurately judge the surgical condition of the surgical patient.

[0058] The imaging control system 20 can also be communicatively connected to a movable operating table, for example, and can send the generated detection image to the physical sign detection device on the movable operating table, enabling the surgeon to perform further analysis and processing operations based on the results of the detection image.

[0059] Figure 4A The structural schematic diagram of the movable operating table according to an exemplary embodiment of the present invention is shown. Figure 4B The structural schematic diagram of the movable operating table according to an exemplary embodiment of the present invention is shown. As Figure 4A shown, the movable operating table 30 includes a physical sign detection device 310, a driving device 320, a base 330, an operating platform 340, a platform adjusting device 350, and a power supply device. As Figure 4B shown, the movable operating table may include a driving device 320, a base 330, an operating platform 340, a platform adjusting device 350, and a power supply device 400.

[0060] In an exemplary embodiment of the present invention, the base 330 is used to support the movable operating table 30 on the ground of the first environment A and the second environment B. That is, the base 330 is used to support the movable operating table 30 so that the movable operating table 30 can move on the ground of the first environment A and the second environment B. The base 330 is, for example, arranged in a flat plate shape, and different devices can be installed or arranged on the base 330 to achieve different functions.

[0061] For example, a physical sign detection device 310 and a driving device 320 are arranged on the base. The physical sign detection device 310 is used to detect the physical signs of the surgical patient lying on the operating platform 340, such as detecting the heart rate, breathing and other physical signs of the surgical patient, so that the medical staff can monitor the physical state of the patient during the operation. The driving device 320 is used to drive the base 330 to move on the ground of the first environment A and the second environment B. Specifically, the driving device 320 is, for example, installed on the side of the base 330 close to the ground.

[0062] In an embodiment of the present invention, as Figure 4A and 4B shown, a power supply device is provided on the movable operating table 30. Figure 4A The power supply device is not shown in Figure 4Bthe power supply device 400 therein, where the power supply device can be arranged together with the vital sign detection device. When the vital sign detection device is not arranged on the movable operating table 30, a power supply device can be arranged on the movable operating table 30, such as Figure 4B the power supply device 400 shown, which is used to supply power to the driving device 320.

[0063] The operation platform 340 is provided with a support plane for the patient to lie on, and the operation platform 340 is provided with a fixing device for fixing the surgical patient on the support plane of the operation platform 340. For example, the fixing device can be limb fixing devices (not shown in the figure) arranged on both sides of the operation platform 340 for fixing the limbs of the surgical patient, and the fixing device can also include a head fixing device 370 for fixing the head of the surgical patient.

[0064] The platform adjusting device 350 is arranged on the side of the base 330 away from the ground and is used to support the operation platform 340. Exemplarily, the bottom end of the platform adjusting device 350 is fixedly arranged on the side of the base 330 away from the ground, that is, fixedly arranged on the upper surface of the base 330. The top end of the platform adjusting device 350 is connected to the operation platform 340 and is used to support the operation platform 340.

[0065] The platform adjusting device 350 has a lifting adjustment function and an angle adjustment function, and can control the angle and height of the operation platform 340 according to the received adjustment instructions. For example, the platform adjusting device 350 is provided with a lifting device that receives a lifting instruction to control the height of the operation platform 340. Another example is that the platform adjusting device 350 is provided with an angle adjusting device that receives an angle adjustment instruction to control the angle of the operation platform 340.

[0066] According to the embodiment of the present invention, by arranging the platform adjusting device 350, the angle and height of the operation platform can be adjusted to meet the requirements of surgeries in different scenarios. At the same time, when moving the movable operating table 30 to the position of the magnet device 10 to detect the target detection position of the surgical patient, it is convenient to adjust the angle and height of the target detection position of the surgical patient to ensure that the target detection position of the surgical patient can be accurately located within the coverage range of the detection signal, thereby achieving no need for manual alignment and improving the accuracy of detecting the target detection position of the surgical patient.

[0067] In an exemplary embodiment of the present invention, the movable operating table 30 further includes an adjustment control panel 360, and the adjustment control panel 360 is used to input adjustment instructions to the platform adjusting device.

[0068] Such as Figure 4A and Figure 4BAs shown, the adjustment control panel 360 has an adjustment instruction input interface (which can be a touch display screen, etc.) for medical staff to input adjustment instructions to adjust the height and angle of the operating platform. Or control other devices and equipment of the movable operating table through the input of adjustment instructions by medical staff.

[0069] In an embodiment of the present invention, the base 330 has a first end O away from the magnet device 10 and a second end P close to the magnet device 10, and the first end O and the second end P are oppositely arranged. The driving device 320 includes a driving wheel 321 provided at the first end of the base 330 and a driven wheel 322 provided at the second end of the base. The driving wheel contains magnetic material, and the driven wheel does not contain magnetic material.

[0070] Exemplarily, the driving wheel 321 can be, for example, a driving wheel driven by a servo motor, so as to control the movable operating table 30 to move between the first environment A and the second environment B according to a driving signal. Since a servo motor is provided on the driving wheel 321, that is, the driving wheel 321 includes magnetic material, the effect of driving is achieved.

[0071] Exemplarily, the driven wheel 322 can be, for example, an omnidirectional wheel, and the omnidirectional wheel is made of a material that does not contain magnetism.

[0072] According to an embodiment of the present invention, since the driving wheel is made of magnetic material and the magnetic material generates a magnetic field, it is easy to interfere with the magnetic field in the magnet device 10. By arranging the driving wheel 321 on the side of the base 330 of the movable operating table 30 away from the magnet device 10, the magnetic material in the driving wheel is located in a weak magnetic field region, thereby reducing or eliminating the influence of the magnetic material in the driving wheel 321 on the magnetic field in the magnet device 10.

[0073] On the other hand, by arranging a driven wheel on the side of the base 330 of the movable operating table 30 close to the magnet device 10, and the driven wheel is made of a non-magnetic material, it can achieve precise control of the moving direction of the movable operating table 30, and at the same time, the driven wheel will not affect the magnetic field of the magnet device 10, ensuring the accuracy of the detection of the magnet device 10.

[0074] In an embodiment of the present invention, the base 330, the operating platform 340 and the platform adjustment device 350 of the movable operating table 30 are made of weak magnetic materials or non-magnetic materials. For example, materials such as stainless steel and engineering plastics are used, which will not generate magnetism and will not interfere with the magnetic field in the magnet device 10, thereby ensuring that the detection images generated by the magnetic resonance imaging device are more accurate.

[0075] Such as Figure 4A and Figure 4BAs shown, the precise tracking device 40 includes a route recognition device 410 disposed on the movable operating table 30 and a trajectory route 420 extending from the second environment B to the first environment A.

[0076] Exemplarily, the route recognition device 410 is disposed on one side of the base 330 close to the magnet device 10 for recognizing the trajectory route 420. The trajectory route 420 may be a trajectory route provided on the ground of the first environment A and the second environment B. The route recognition device 410 is disposed on the side of the base 330 facing the ground, which can effectively recognize the trajectory route 420, thereby controlling the movement of the movable operating table 30. At the same time, the route recognition device 410 is relatively close to the trajectory route 420, improving the recognition accuracy.

[0077] In an embodiment of the present invention, the route recognition device 410 recognizes the trajectory route 420 through light recognition or induction recognition. The route recognition device 410, for example, recognizes the trajectory route through a light recognition method, such as visible light recognition, ultraviolet light or infrared light recognition. The route recognition device 410 may also be, for example, through an induction recognition method, such as a distance sensor, etc., for induction.

[0078] Exemplarily, the route recognition device 410 includes an optical camera, and the trajectory route 420 includes a guiding band having at least one set color. For example, the trajectory route adopts a guiding band composed of black and white lines. Again, for example, the trajectory route may adopt a guiding band of other colors that are easily recognized by the optical camera.

[0079] According to this embodiment, by using an optical camera to recognize the trajectory route, and at the same time the trajectory route adopts a guiding band with a set color, the transformation of devices located in different environments is reduced, and the cost is lowered. For example, by using a guiding band having at least one set color and laying it flat on the ground of the first environment A and the second environment B, it is convenient for the optical camera to recognize the trajectory route. The guiding band, for example, may be a material with a certain adhesiveness, directly adhered to the ground, and by setting it into a specific shape, the navigation of the movable operating table is realized, so that the movable operating table moves according to the shape of the trajectory route.

[0080] In an embodiment of the present invention, as Figure 1 and Figure 2 shown, the trajectory route 420 includes a first interval trajectory route 421, a second interval trajectory route 422, and a third interval trajectory route 423, and the second interval trajectory route 422 is located between the first interval trajectory route 421 and the third interval trajectory route 423.

[0081] During the process of moving the movable operating table, the speed of moving from the second environment to the first environment is different to meet the requirements of different stages and prevent accidents during the moving process.

[0082] Exemplarily, the moving speed of the movable operating table on the first interval trajectory route and the third interval trajectory route is less than the moving speed of the movable operating table on the second interval trajectory route.

[0083] When the surgical patient on the movable operating table has completed the operation to a certain extent and it is necessary to perform real-time detection on the diseased position or tissue at the surgical site to determine the specific process of the operation. At this time, the operation is stopped, and the movable operating table 30 is moved to the position of the magnet device 10 by controlling the precise tracking device 40. During the start of the movement, the surgical patient and the vital sign detection device on the movable operating table 30 should not generate violent shaking. Therefore, it is necessary to move at a slower speed. After the movable operating table 30 moves smoothly, the moving speed can be increased so that the surgical patient can be quickly moved to the position of the magnet device 10, thereby reducing the moving time during the movement. When approaching the magnet device 10, the moving speed is reduced to prevent the surgical patient from colliding with the magnet device during the detection, causing secondary injury to the surgical patient or accidents.

[0084] According to an embodiment of the present invention, the precise tracking device 40 is configured to identify the trajectory route 420 through the route recognition device 410, and control the driving device 320 to move the movable operating table 30 between the first environment A and the second environment B, so as to achieve the purpose of real-time detection of the target position of the surgical patient during the operation.

[0085] In addition, when the precise tracking device 40 moves the movable operating table 30 from the second environment B to the first environment A, the target detection position of the surgical patient on the movable operating table 30 is within the detection signal coverage range. That is, when the precise tracking device 40 moves from the second environment B to the first environment A, there is no need to align the target detection position of the surgical patient with the detection signal area in the magnet device 10, and the precise tracking device 40 can directly achieve the function of automatic alignment.

[0086] Figure 5A Schematically shows a structural diagram of the head fixing device of the magnetic resonance imaging device for surgical operations according to an embodiment of the present invention. Figure 5B Schematically shows a structural diagram of the radio frequency coil of the magnetic resonance imaging device for surgical operations according to an embodiment of the present invention. Figure 5C Schematically shows a side structural diagram of the radio frequency coil of the magnetic resonance imaging device for surgical operations according to an embodiment of the present invention.

[0087] As Figure 5AAs shown, the fixing member includes a head fixing device 370 disposed at one end of the surgical platform near the magnet device. The head fixing device 370 is configured to fix the head of the surgical patient so that the surgical area of the head of the surgical patient can be located within the support plane or on both sides of the support plane.

[0088] For example, when the surgical patient lies flat or lies prone on the support plane of the surgical platform, the head fixing device 370 fixes the head of the surgical patient, so that the surgical area located on the head of the surgical patient can be adjusted at different positions. The surgical area can be higher than the support plane of the surgical platform, or the surgical area can be located on the support plane of the surgical platform, or the surgical area can be lower than the support plane of the surgical platform, so as to facilitate the adjustment of the head of the surgical patient, make the surgical area of the head of the surgical patient located at a suitable height and angle, and facilitate the medical staff to perform the operation and detect the target detection position of the surgical area through the magnetic device.

[0089] As Figure 5A shown, the head fixing device 370 includes: a first support member 371 and head fixing pins 372.

[0090] The first support member 371 includes a U-shaped portion formed by two parallel support arms 3711 and a connecting portion 3712 perpendicular to the support arms 3711 of the U-shaped portion. One end of the connecting portion 3712 is hinged to one end of the surgical platform 340, and this end of the surgical platform 340 is close to the magnet device 10, that is, the connecting portion 3712 can bend in the vertical direction relative to the surgical platform 340, thereby driving the U-shaped portion formed by the support arms 3711 to move, and controlling the surgical area of the head of the surgical patient to be located within the support plane or on the upper side or the lower side of the support plane.

[0091] The head fixing pins 372 are arranged on the opposite side walls of the two support arms of the U-shaped portion and are used to fix the head of the surgical patient. For example, one head fixing pin 372 is arranged on the first support arm of the U-shaped portion, and another head fixing pin 372 is arranged on the second support arm of the U-shaped portion. The two head fixing pins are arranged oppositely to fix the head of the surgical patient.

[0092] In the embodiment of the present utility model, the oppositely arranged head fixing pins 372 can be adjusted, for example, by a distance adjusting device to adjust the distance between the oppositely arranged head fixing pins 372, so as to be used to fix the heads of different surgical patients. The distance adjusting device can be, for example, an adjusting knob. By rotating the adjusting knob, the oppositely arranged head fixing pins 372 move relatively, and one or two adjusting knobs can be provided.

[0093] In an exemplary embodiment of the present utility model, the magnetic resonance imaging device 100 further includes a radio frequency coil 380, which is detachably connected to the head fixing device 370 and is used for receiving radio frequency signals. The radio frequency coil includes a phased array coil.

[0094] As Figure 5B and Figure 5C shown, the radio frequency coil 380 is disposed on the upper side and / or the lower side of the head fixing pins 372 for receiving radio frequency signals.

[0095] Exemplarily, when the surgical patient X lies or lies prone on the surgical platform 340, the head is fixed by the head fixing device 370, and the radio frequency coil 380 respectively covers the back brain position of the head of the surgical patient M and the facial position of the head of the surgical patient X, so as to realize the function of receiving radio frequency signals.

[0096] In an exemplary embodiment of the present utility model, the magnetic resonance imaging device further includes an obstacle detection device 390.

[0097] The obstacle detection device 390 is used for detecting obstacles on the periphery of the movable operating table 30 when the precise tracking device 40 controls the driving device 320 to move the movable operating table 30 between the first environment A and the second environment B, and controlling the movable operating table to stop moving when an obstacle is detected.

[0098] Exemplarily, multiple obstacle detection devices 390 can be provided, which are respectively disposed in the first environment A and the second environment B. During the movement of the movable operating table 30, it is determined whether there are obstacles on the periphery of the trajectory route of the movable operating table 30. When there are obstacles on the periphery of the movable operating table 30, the movable operating table is controlled to stop moving and a prompt message is generated, such as a prompt on the adjustment control panel or a voice prompt.

[0099] In an embodiment of the present utility model, the magnetic resonance imaging device further includes a movable diagnostic bed 50. The movable diagnostic bed 50 is disposed in the first environment A, for example, in a diagnostic room. The movable diagnostic bed 50 can move relative to the magnet device 10 so that the target diagnostic position of the diagnostic patient located on the movable diagnostic bed 50 is within the detection signal coverage range.

[0100] Exemplarily, the diagnostic patient on the movable diagnostic bed 50 enters the cylindrical through hole 101 of the magnet through the second end N of the magnet device 10, and the target diagnostic position of the diagnostic patient is within the detection signal coverage range, so as to facilitate the diagnosis of the diagnostic patient.

[0101] In an embodiment of the present utility model, the magnetic resonance imaging device 100 further includes an imaging state detection device 60. The imaging state detection device 60 is used to detect the position state of a movable operating table or a movable diagnostic couch in the magnet device, and control the movement of the movable operating table or the movable diagnostic couch according to the position state.

[0102] Exemplarily, the imaging state detection device 60 is an AI camera, which can detect the position states of the surgical patient on the movable operating table and the diagnostic patient on the movable diagnostic couch in the magnet. For example, when the surgical patient on the movable operating table 30 is to enter the magnet device 10 for detection, the imaging state detection device 60 determines whether there is a diagnostic patient on the movable diagnostic couch 50 in the magnet device 10. If there is a diagnostic patient on the movable diagnostic couch 50 undergoing diagnosis, it controls the movable operating table 30 to stop moving and generates a prompt message.

[0103] Another example is that when the diagnostic patient on the movable diagnostic couch 50 is to enter the magnet device 10 for diagnosis, the imaging state detection device 60 determines whether there is a surgical patient on the movable operating table 30 in the magnet device 10. If there is a surgical patient on the movable operating table 30 undergoing detection, it controls the movable diagnostic couch 50 to stop moving and generates a prompt message.

[0104] In an embodiment of the present utility model, the imaging state detection device 60 is, for example, an AI camera, which does not require manual judgment and recognition, can achieve autonomous recognition, improve efficiency, avoid the problem of conflicts between the movable diagnostic couch and the movable operating table, and improve the use efficiency of the magnetic resonance imaging device.

Figure 6C Schematically shows a second angle schematic diagram of the cooperation between the movable operating table of the magnetic resonance imaging device for surgical operations and the magnet device according to another embodiment of the present utility model.

[0106] Such as Figure 6A 、 Figure 6B and Figure 6CAs shown, when medical staff input an instruction on the adjustment control panel of the magnetic resonance imaging device 100, the precise tracking device 40 identifies the trajectory route 420 extending from the second environment to the first environment through the route recognition device 410 according to the instruction, and controls the driving device 320 to move the movable operating table 30. When passing through different sections of the trajectory route 421, different moving speeds are adopted for movement. And when the movable operating table 30 moves to the position of the magnet device 10 in the first environment, the head fixing device on the operating platform enters the cylindrical through hole, so that the target detection position of the head of the surgical patient is within the coverage range of the detection signal of the magnet device.

[0107] According to an embodiment of the present invention, by fixedly arranging the magnet device in the first environment with radio frequency shielding, the interference of external factors on the magnet device can be reduced. By providing a movable operating table, the surgical patient during the operation can be smoothly and accurately moved from the operating room with an operating environment to the set position of the magnetic resonance imaging device with a radio frequency shielding environment, avoiding accidents during the movement of the patient. By providing a precise tracking device, precise navigation of the movable operating table can be achieved, and the position to be detected of the surgical patient can be accurately moved to a specific area of the magnetic resonance imaging device for alignment, so as to detect the surgical position of the surgical patient during the operation to generate a detection image and improve the imaging accuracy.
