Description

Technical Field

[0001] The present application relates to the field of magnetic resonance imaging (MRI), and more particularly, the present application relates to MRI facilities. Background Art

[0002] Intraoperative MRI aims to combine surgical procedures (e.g., neurosurgery) with MRI to accurately locate lesions with the help of imaging technology. Similarly, interventional MRI has also been successfully used in interventional treatments (e.g., bone marrow, liver, and breast lesion biopsies and brain tumor ablation) to provide real-time image guidance. Compared with imaging techniques such as computed tomography (CT), ultrasound imaging, and infrared imaging, MRI has the advantages of not requiring contrast agents, not ionizing radiation, and being able to perform two-dimensional and three-dimensional imaging.

[0003] However, in practice, both intraoperative MRI and interventional MRI have the following problems: high-field strength (e.g., 1.5T-3.0T) MRI can easily cause patients to be burned by overheated surgical instruments (e.g., needles or catheters) during surgical operations or interventional treatments; and the scanning aperture of currently commercially available MRI equipment is between 60cm and 70cm, which is not conducive to surgeons operating surgical instruments in the scanning aperture during surgical operations or interventional treatments on patients. At the same time, the MRI equipment currently used in intraoperative MRI, the MRI equipment used in interventional MRI, and the MRI equipment used in conventional scanning diagnosis are independent of each other, so it is necessary to configure an expensive MRI equipment for each surgical operating room, interventional treatment room, and diagnostic scanning room, resulting in low utilization of MRI equipment and increased costs.

Thus, the operating room 102 serves as both a surgical operating room in which a surgical operation (e.g., a neurosurgery) can be performed, and an interventional treatment room in which a (minimally invasive) interventional treatment can be performed.

[0028] A first patient table is arranged in the operating room 102, for example, the first patient table includes: a first bed board 106, the first bed board 106 is configured for the first patient to lie down; and a first support frame 108 for supporting the first bed board 106, the first support frame 108 can be raised and lowered by means of, for example, a hydraulic lifting cylinder and includes a first base 110. The first base 110 can be fixed on the floor of the operating room 102 according to a first mark (not shown). Alternatively, the first base 110 can also be movable, but can return to the first initial position according to the first mark.

[0029] The exemplary MRI facility 100 further includes a scanning room 202 spatially connected to the operating room 102, and the scanning room 202 is configured to provide an enclosed space whose cleanliness meets the medical standards for scanning diagnosis, so that a second patient 400 who only needs to undergo magnetic resonance imaging can be scanned by the MRI device 302 described below in the enclosed space. A second patient table is arranged in the scanning room 202, for example, the second patient table includes: a second bed board 206, the second bed board 206 is configured for the second patient 400 to lie on; and a second support frame 208 for supporting the second bed board 206, the second support frame 208 can be raised and lowered by means of, for example, a hydraulic lifting cylinder and includes a second base 210. The second base 210 can be fixed on the floor of the scanning room 202 according to a second mark. Alternatively, the second base 210 can also be movable, but can return to the second initial position according to the second mark.

[0030] The exemplary MRI facility 100 further includes a door (not shown) between the operating room 102 and the scanning room 202. When the door is closed, the operating room 102 and the scanning room 202 are spatially separated from each other so that the cleanliness of the operating room 102 and the cleanliness of the scanning room 202 do not interfere with each other. When the door is opened, the MRI device 302 described below can be moved between the scanning room 202 and the operating room 102.

[0031] As mentioned above, the exemplary MRI facility 100 also includes an exemplary MRI device 302 that is shared by the operating room 102 and the scanning room 202. The exemplary MRI device 302 includes a superconducting magnet device, a gradient coil device, and an RF coil device that are coaxially arranged from the outside to the inside in the radial direction as known. The scanning aperture 304 is defined by the superconducting magnet device, the gradient coil device, and the RF coil device, and the scanning aperture 304 has a central axis, and a first opening 306 and a second opening 308 located at both ends of the scanning aperture 304 along the central axis. The exemplary MRI device 302 also includes one or more control devices that control the superconducting magnet device and the gradient coil device to generate a desired magnetic field and control the RF coil device to generate a desired RF excitation pulse (or RF signal). The one or more control devices are electrically connected and / or communicated with the superconducting magnet device, the gradient coil device, the RF coil device, and their auxiliary electrical devices (for example, various amplifiers and various sensors, etc.) through one or more electrical lines and / or data transmission lines to control the operation of the entire MRI device 302.

[0032] For example, the one or more control devices may activate the superconducting magnet device to cause the superconducting magnet device to generate a main magnetic field B distributed substantially along or parallel to the central axis within the scanning aperture 304. o The one or more control devices may also activate the gradient coil device to cause the X-axis gradient coil, the Y-axis gradient coil, and the Z-axis gradient coil in the gradient coil device to generate a gradient magnetic field for spatially encoding the MR signal. The control device may also activate the RF coil device, for example, a body coil for transmitting RF excitation pulses, to cause the RF coil to generate an RF magnetic field B for scanning the desired internal structure and tissue of the patient. i , RF magnetic field B i In the scanning aperture 304, perpendicular to the main magnetic field B o Alternatively, the one or more control devices may also activate an RF coil device, for example, a body coil for receiving MR signals, to cause the RF coil device to receive the RF magnetic field B from the patient. i induced MR signal.

[0033] Alternatively, the scanning aperture 304 is defined only by the superconducting magnet device and the gradient coil device, and the RF coil device can be configured as a portable RF receiving coil device separated from the superconducting magnet device and the gradient coil device, and the portable RF receiving device has the characteristics of flexibility, light weight, and can be directly stored in a bed board (e.g., the first bed board 106 and the second bed board 206). In this case, taking the use of the exemplary MRI device 302 in the operating room 102 as an example, when the first patient is ready to be scanned using the exemplary MRI device 302, the portable RF receiving device will be extended from the first bed board 106 to cover at least a portion of the body (e.g., the torso) of the first patient.

[0034] In order to realize the movement of the exemplary MRI device 302 between the operating room 102 and the scanning room 202, the MRI device 302 includes a ground walking mechanism 310, which may include one or more tracks, one or more Mecanum wheels or other movable devices to provide linear movement and turning movement. For example, the ground walking mechanism 310 is driven by a servo motor, and the servo motor is controlled by means of a positioning device.

[0035] Optionally, the positioning device includes one or more first light sources mounted at the first mark to be associated with the first patient table. Similarly, the positioning device includes one or more second light sources mounted at the second mark to be associated with the second patient table. The positioning device also includes one or more sensors mounted on the exemplary MRI device 302 for detecting light beams (e.g., laser beams) emitted by the one or more first light sources or the one or more second light sources, whereby the positioning device is configured to control the exemplary MRI device 302 to be positionably moved to a desired position by means of signals from the one or more sensors.

[0036] Additionally or alternatively, multiple optical sensors may be installed in the operating room 102 and the scanning room 202 to receive modulated infrared rays emitted by an infrared transmitter installed on the exemplary MRI device 302 so as to accurately locate the position of the exemplary MRI device 302 in the room.

[0037] In addition or alternatively, the positioning device includes an industrial camera, which includes an optical lens, a timing and synchronization signal generator, a vertical driver, and an analog / digital signal processing circuit. The optical lens converts the digital image capture target into an image signal and transmits it to a dedicated image processing system. The image system performs various operations on these signals to extract the characteristics of the target, and then controls the equipment action on site according to the judgment results.

[0038] Additionally or alternatively, the positioning device includes an ultrasonic positioning device, which mainly uses reflection ranging and determines the position of the object through algorithms such as triangulation positioning.

[0039] In addition or alternatively, the positioning device includes a distance measurement and navigation device. The navigation technology used by the distance measurement and navigation device is mainly used to scan and measure the surrounding environment with a laser two-dimensional scanner, obtain measurement data, and then realize navigation in combination with a navigation algorithm. The navigation sensor is usually implemented using a safety laser scanner with a safety function, because the use of a safety laser scanner can realize the safety function while also realizing the navigation measurement function.

[0040] Additionally or alternatively, the positioning device includes a SLAM laser navigation device, which is a natural navigation method that does not require the use of reflectors. It no longer requires auxiliary navigation signs (QR codes, reflectors, etc.), but uses the natural environment in the working scene, such as pillars and walls in the room, as positioning references to achieve positioning navigation.

[0041] Additionally or alternatively, the positioning device includes visual navigation, which is also a navigation method based on the SLAM algorithm. This navigation method collects image information of the operating area through a vehicle-mounted visual camera, and performs positioning and navigation through processing of the image information.

[0042] Additionally or alternatively, the positioning device includes a fiber optic shape sensing device, which generally includes: a flexible optical fiber having a certain length and including a single-core or multi-core optical fiber; an optical console configured to send light to the optical fiber and receive light reflected from the optical fiber; and a 3D shape reconstructor configured to obtain optical data related to the light reflected from the optical fiber from the optical console, and reconstruct the 3D shape of the optical fiber based on the optical data, so as to thereby locate the position of the exemplary MRI device 302.

[0043] In addition, a GPS positioning system may be used to ensure the movement accuracy of the exemplary MRI device 302 . For example, the movement accuracy of the exemplary MRI device 302 may reach ≤1 mm.

[0044] Optionally, in order to reduce the possibility of causing movement errors of the exemplary MRI device 302, the moving distance of the exemplary MRI device 302 between the operating room 102 and the scanning room 202 should be minimized as much as possible, and at the same time, the complexity of the moving trajectory of the exemplary MRI device 302 should be minimized, that is, the straight moving trajectory of the exemplary MRI device 302 should be maintained as much as possible. Figure 3When the exemplary MRI device 302 is prepared to scan the first patient who is about to or is undergoing a surgical operation or interventional treatment in the operating room 102, the exemplary MRI device 302 is moved to the first position engaged with the first patient table by means of the floor walking mechanism 310. When the exemplary MRI device 302 is moved to the first position, at least a portion of the first bed plate 106 extends from the first opening 306 into the scanning aperture 304, and thus the first patient lying on the first patient table enters the scanning aperture 304 from the first opening 306. Figure 4 When the exemplary MRI device 302 is prepared to scan the second patient 400 in the scanning room 202, the exemplary MRI device 302 is moved to the second position engaged with the second patient table by means of the floor walking mechanism 310. When the exemplary MRI device 302 is moved to the second position, at least a portion of the second bed plate 206 extends from the second opening 308 into the scanning aperture 304, and thus the second patient 400 lying on the second patient table enters the scanning aperture 304 from the second opening 308 opposite to the first opening 306.

[0045] When the optical fiber shape sensing device is used to position the exemplary MRI device 302, an optical fiber is laid along a straight line between a first position and a second position on the floor of the operating room 102 and the scanning room 202, and a pressing component is arranged at the bottom of the floor walking mechanism 310 corresponding to the optical fiber, and a certain pressure generated by the pressing component on the optical fiber is applied to deform the optical fiber. When the exemplary MRI device 302 moves between the first position and the second position, the position change of the exemplary MRI device 302 can be measured based on the deformation of the optical fiber.

[0046] Optionally, the first bed board 106 of the first patient table in the operating room 102 and the second bed board 206 of the second patient table in the scanning room 202 are aligned along a straight line movement trajectory of a floor walking mechanism 310 of the exemplary MRI device 302, so that the floor walking mechanism 310 can directly move the exemplary MRI device 302 along the straight line movement trajectory to reach the first position and the second position, thereby the first patient table and the second patient table will be efficiently coordinated with the exemplary MRI device 302.

[0047] Optionally, the scanning aperture 304 includes a patient table engagement region 312, which includes a first section proximate to the first opening 306 and a second section proximate to the second opening 308. The at least a portion of the first bed plate 106 protrudes toward the exemplary MRI device 302 relative to the first support frame 108, and the lower surface of the at least a portion of the first bed plate 106 is shaped to have a first contour. When the at least a portion of the first bed plate 106 extends from the first opening 306 into the scanning aperture 304 of the exemplary MRI device 302 so that the exemplary MRI device 302 moves to the first position, the first contour engages with the first section of the patient table engagement region 312 to assist the first bed plate 106 and thus the first patient in being positioned in a position suitable for being scanned by the exemplary MRI device 302. Similarly, the at least a portion of the second bed plate 206 protrudes toward the exemplary MRI device 302 relative to the second support frame 208, and the lower surface of the at least a portion of the second bed plate 206 is shaped to have a second contour. When the at least a portion of the second couch board 206 extends from the second opening 308 into the scanning aperture 304 of the exemplary MRI device 302 so that the exemplary MRI device 302 moves to the second position, the second contour engages with the second section of the patient table engagement region 312 to assist in positioning the second couch board 206 and thus the second patient 400 in a position suitable for being scanned by the exemplary MRI device 302. Optionally, the patient table engagement region 312 runs through the scanning aperture 304, that is, the first section and the second section are identical in cross-sectional contour or shape and may at least partially overlap, so that the length of the scanning aperture 304 is reasonably shortened.

[0048] For example, the first contour and the second contour each include one or more characteristic protrusions, and the patient table engagement area 312 includes one or more characteristic grooves extending through the scanning aperture 304, so that the one or more characteristic protrusions are configured to be correspondingly inserted or slid into the one or more characteristic grooves to locate the radial position of the first patient table and the second patient table relative to the scanning aperture 304.

[0049] It can be seen that the exemplary MRI apparatus 302 will achieve a symmetrical design in function, that is, the first patient and the second patient entering the scanning aperture 304 of the exemplary MRI apparatus 302 from the first opening 306 and the second opening 308 respectively can be scanned equally by the exemplary MRI apparatus 302 .

[0050] When the exemplary MRI device 302 is not in operation, the exemplary MRI device 302 needs to be separated from the first patient table and the second patient table. In this case, the exemplary MRI device 302 will be located between the first patient table and the second patient table, that is, between the first position and the second position. Optionally, when the exemplary MRI device 302 is not in operation, the exemplary MRI device 302 can be completely located in the operating room 102; or the exemplary MRI device 302 can be completely located in the scanning room 202, so that the operating room 102 can be used to perform other operations that do not require the use of intraoperative MRI methods or interventional MRI methods when the door is closed.

[0051] Optionally, when the exemplary MRI device 302 is not in operation, the door is opened, a portion of the exemplary MRI device 302 is located in the operating room 102, and the remaining portion is located in the scanning room 202, that is, referring to Figure 5 , an exemplary MRI device 302 is located between the operating room 102 and the scanning room 202 .

[0052] In the exemplary MRI device 302 provided in the present application, the diameter of the scanning aperture 304 is enlarged, for example, the diameter range of the scanning aperture 304 is enlarged to between 80 cm and 120 cm, so that when the exemplary MRI device 302 is used for surgery or interventional surgery in the operating room 102, the surgeon can conveniently operate the surgical instrument 402 located in the scanning aperture 304 during the surgery or interventional surgery.

[0053] In the exemplary MRI device 302 provided in the present application, the exemplary MRI device 302 implements a magnetic field strength of medium to low magnetic field strength, for example, the range of the implemented magnetic field strength is between 0.3T and 1.5T, preferably between 0.5T and 1.0T, for example, 0.55T, to prevent the surgical instrument 402 (for example, a needle or a catheter) used in the operating room 102 from overheating due to the high field strength of the MRI device 302.

[0054] Optionally, since the exemplary MRI device 302 is configured as an open MRI device 302 without a magnetic shielding function, both the operating room 102 and the scanning room 202 are configured as magnetic shielding rooms, and the doors are configured as radio frequency shielding doors.

[0055] It is to be understood that for the sake of clarity, descriptions of other components of the MRI device 302 , such as the housing, support components and / or suspension components, and end caps, are omitted herein.

[0056] In practice, on the one hand, when the exemplary MRI device 302 is used to perform, for example, interventional MRI in the operating room 102 to treat a first patient with a head lesion in combination with interventional treatment, the first patient can lie on the first patient table detached from the exemplary MRI device 302 in advance, and then the exemplary MRI device 302 is moved to the first position engaged with the first patient table, the door is closed, a closed space whose cleanliness meets the medical standards of interventional treatment is formed, and the exemplary MRI device 302 is used to perform a preoperative scan on the head of the first patient. The surgeon can formulate a surgical plan based on the results of the preoperative scan, and operate the surgical instrument 402 (e.g., needle and / or catheter) in the scanning aperture 304 based on the surgical plan to perform interventional surgery such as puncture on the head of the first patient. During this period, the exemplary MRI device 302 can also be used to perform a real-time scan on the head of the first patient during the operation to determine whether each stage of the operation has achieved the expected purpose. After the interventional surgery is completed, a postoperative scan can also be performed on the head of the first patient. It can be seen that during the interventional treatment in the operating room 102, the exemplary MRI device 302 can always be located at the first position to perform real-time scanning at any time to provide real-time image guidance for the interventional treatment.

[0057] In addition, when the exemplary MRI device 302 is used to perform, for example, intraoperative MRI in the operating room 102 to treat a first patient with a head lesion in conjunction with a neurosurgery, the exemplary MRI device 302 can be moved between a first position and a third position during the surgical procedure, and the third position is located between the first position and the second position along a straight line between the first position and the second position, so that the exemplary MRI device 302 located at the third position is located in the operating room 102 but not engaged with the first patient table, thereby facilitating the surgeon to perform the surgical procedure.

[0058] On the other hand, when the second patient 400 is subjected to routine scanning diagnosis in the scanning room 202 using the exemplary MRI device 302, the second patient can lie on the second patient table detached from the exemplary MRI device 302 in advance, and then the exemplary MRI device 302 is moved to the second position engaged with the second patient table, and the door is closed to form a closed space whose cleanliness meets the medical standards for scanning diagnosis, and the second patient is scanned using the exemplary MRI device 302 to generate the results of the routine scanning diagnosis.

[0059] Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are only for illustration, not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
