[0043] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0045] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first resistor may be referred to as a second resistor, and similarly, a second resistor may be referred to as a first resistor. Both the first resistor and the second resistor are resistors, but they are not the same resistor.

[0046] It can be understood that the “connection” in the following embodiments should be understood as “electrical connection”, “communication connection”, etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0047] It can be understood that “at least one” means one or more, “plurality” means two or more, and “at least a portion of an element” means a part or all of an element.

[0048] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0049] In the magnetic resonance imaging system, the patient support device (bed) communicates with the host computer through the medical imaging equipment. The patient support device (bed) senses the magnetic signal and transmits the magnetic signal to the medical imaging equipment through the interface with the medical imaging equipment. The medical imaging equipment converts the magnetic signal into a signal supported by the host computer, such as an OPT signal (optical signal) and an electrical signal, so that the host computer processes the received signal to obtain the imaging result.

[0050] The interface connection between the patient support device (bed) and the medical imaging device is achieved by setting up interface modules respectively, and establishing a communication link through the matching connection between the two interface modules. However, in the conventional technology, when the two interface modules are connected, the link connection is sometimes unreliable.

[0051] Medical imaging systems require quick and convenient transportation of special test subjects and critically ill test subjects. The patient support device needs to be pluggable and movable. During the transportation process, the patient support device must be detached from the system main frame, and after successful docking, it is required not to affect the reliable operation of the normal scanning and imaging workflow. The RF receiving link is responsible for signal acquisition and coil control in the scanning and imaging workflow. A part of the RF receiving link must be integrated with the patient support device, and the reliability and convenience of docking with the other part of the RF receiving link located in the main frame has become a great challenge.

[0052] The electrical interface between the traditional pluggable detection object carrier and the magnet rack is extremely complex, especially for systems that support high channel counts and high-density coils, where the total number of RF pins and DC control pins is often more than 200. Electrical connections are prone to: wear caused by repeated plugging and unplugging of pins; bending caused by docking angle deviation. The more receiving channels the system has and the more pins it has, the greater the probability of electrical connection abnormalities caused by the above failure modes. Electrical connection abnormalities include open circuits, short circuits, and impedance discontinuities in the RF path. At the same time, due to the plug-in and pull-out force of the pin interconnection, the more pins there are, the greater the thrust used by the detection object carrier when plugging and unplugging without electricity. For example, the actual plug-in and pull-out force of about 200 pins is about 350 Newtons, and the channel expansion to 400 pins will be as high as 700 Newtons, which has reached the level that ordinary people cannot complete plugging and unplugging. In the process of docking, the inertia of the pluggable detection object carrier can be used to compensate for the lack of human thrust. However, during the unplugging process, in the abnormal case of motor failure and no electric assist, it is almost impossible to pull it out by holding the tail handle and pulling it directly. If a lever mechanism is used to assist plugging and unplugging, an additional operating pedal or joystick is required, which reduces convenience.

[0053] During the implementation process, the applicant discovered that in the conventional technology, when two interface modules are docked, unreliable communication in the medical imaging system may sometimes occur. One of the reasons is that the docking mechanism in the conventional medical imaging system contains a lot of impurities such as dust, liquid, and foreign matter.

[0054] In an exemplary embodiment, Figure 1 and Figure 2 As shown, a medical imaging device 10 is provided, comprising:

[0055] a scanner unit 102 , the scanner unit 102 at least partially enclosing a patient accommodation area;

[0056] The scanner unit 102 is equipped with a receiving mechanism 100 , and the receiving mechanism 100 is provided with a first ventilation channel 111 . When the receiving mechanism 100 and the docking mechanism 200 of the patient support device 20 are in a docking state, the first ventilation channel 111 is opened.

[0057] The medical imaging device 10 may be a magnetic resonance imaging device. The scanner unit 102 is used to perform magnetic resonance scanning and imaging on the detection object. In this case, the scanner unit 102 may have a main magnet, a gradient coil, a radio frequency coil and other component structures to complete magnetic resonance scanning and imaging.

[0058] The receiving mechanism 100 is used to dock with the docking mechanism 200 of the patient support device 20 , and the medical imaging device 10 can communicate with the patient support device 20 through the receiving mechanism 100 .

[0059] The patient support device 20 may be a device for carrying a medical test object. The docking mechanism 200 may be a mechanism in the patient support device 20 for docking the medical imaging device 10 .

[0060] For example, the medical imaging device may be provided with a scanner unit 102, and the scanner unit 102 may at least partially enclose a patient accommodation area. During the scanning and imaging process, the patient may be located in the patient accommodation area to facilitate scanning and imaging of the patient. The scanner unit 102 may be provided with Figure 2 The docking mechanism 100 shown can be used to dock with the docking mechanism 200 of the patient support device 20 to facilitate communication between the medical imaging device 10 and the patient support device 20, which is beneficial for the scanner unit 102 to perform medical scanning on the patient.

[0061] The receiving mechanism 100 may be provided with a first ventilation channel 111. When the receiving mechanism 100 and the docking mechanism 200 of the patient support device 20 are in a docking state, the medical imaging device 10 may perform medical imaging communication with the patient support device 20, and at the same time, the first ventilation channel 111 may be turned on. The first ventilation channel 111 may be connected to a first fan 101 provided on the medical imaging device 10. The turned-on first ventilation channel 111 may dissipate heat for the medical imaging device 10, and at the same time, dust and other impurities on the docking surface of the medical imaging device 10 and the patient support device 20 may be purged through the first ventilation channel 111 to prevent the impurities on the docking surface from affecting the communication between the medical imaging device 10 and the patient support device 20, thereby improving the communication reliability of the medical imaging device 10.

[0062] Optionally, the medical imaging device 10 can be other medical imaging devices other than MR devices, such as CT, XR, and RT devices. In this case, the scanner unit can be provided with a ray source and a detector, and the ray source and the detector are correspondingly installed on the scanner unit 102 so that the rays emitted by the ray source can be received by the detector, so that medical imaging of the detection object can be achieved. Another example is a PET device. In this case, the scanner unit can be provided with a PET detector module to complete PET scanning and imaging. In this case, the PET detector module can be provided with an annular detector and a data acquisition unit. The annular detector and the data acquisition unit can be correspondingly installed on the scanner unit 102. During the scanning and imaging process, the annular detector can detect the patient's positrons and the corresponding gamma rays. The data acquisition unit can collect information on the positrons and gamma rays detected by the detector and convert them into digital signals to achieve imaging.

[0063] In some specific embodiments, the medical imaging device includes: a scanner unit, the scanner unit at least partially encloses a patient accommodation area; the scanner unit is equipped with a receiving mechanism, the receiving mechanism is provided with a first ventilation channel, and when the receiving mechanism and the docking mechanism of the patient support device are in a docking state, the first ventilation channel is opened. In this way, through the above structure, the first ventilation channel can provide heat dissipation for the scanner unit, and can provide airflow for the gap of the docking surface of the medical imaging device, so that the docking surface of the receiving mechanism of the medical imaging device and / or the interior of the medical imaging device can be kept in a clean state, so that the communication reliability of the communication receiving link can be improved, and the communication reliability of the medical imaging device during the medical imaging process can be improved.

[0064] In an exemplary embodiment, Figure 1 and Figure 2 As shown, the receiving mechanism 100 is further provided with a first fan 101 , and an air outlet of the first fan 101 is communicated with the first ventilation channel 111 .

[0065] The first fan 101 may be a fan for providing airflow, and may be a fan arranged in the medical imaging device 10 . The airflow provided by the fan may be transmitted to the gap of the docking surface through the first ventilation channel 111 connected thereto.

[0066] Exemplarily, the receiving mechanism 100 may be provided with a first fan 101, and the air outlet of the first fan 101 is connected to the first ventilation channel 111. The first ventilation channel 111 may be connected to the air outlet of the first fan 101 and the gap of the docking surface, respectively, and the gap may be connected to the outside. For example, the first end of the first ventilation channel 111 may be connected to the air outlet of the first fan 101, and the second end of the first ventilation channel 111 may be connected to the outside through the gap, so that the airflow provided by the first fan 101 can be transmitted to the docking surface through the first ventilation channel 111, and the impurities such as dust, liquid, foreign matter, etc. remaining on the docking surface can be blown out by the airflow to keep the docking surface clean, thereby improving the communication reliability of the medical imaging system.

[0067] In some specific embodiments, the receiving mechanism is further provided with a first fan, and the air outlet of the first fan is connected to the first ventilation channel 111. In this way, the first fan can provide heat dissipation for the medical imaging device, and the dust, liquid, foreign matter and other impurities remaining on the docking surface can be blown out by the airflow, so as to keep the docking surface between the medical imaging device and the patient carrier device clean.

[0068] In an exemplary embodiment, the receiving mechanism is further provided with a first fan, and an air outlet of the first fan is communicated with the first ventilation channel; the scanner unit is further provided with a driving device for driving the first fan.

[0069] The driving device may be a device for driving the first fan.

[0070] Exemplarily, the scanner unit may be provided with a driving device, and the first fan may be driven by the driving device so that the first fan can provide airflow to blow toward the first ventilation channel. In this way, the driving of the first fan can be realized by the driving action of the driving device.

[0071] In an exemplary embodiment, Figure 2 As shown, the receiving mechanism 100 is provided with a receiving portion, and the receiving portion is used to match and dock with the guide component 213 in the docking mechanism 200.

[0072] For example, the receiving mechanism 100 may be provided with a receiving portion, and the receiving portion may have a receiving opening, and the shape of the guide component 213 is matched with the shape of the receiving opening so that the guide component 213 can enter the receiving opening. During the docking process between the receiving mechanism 100 and the docking mechanism 200 of the patient support device 20, the guide component 213 may serve as a guide pin to guide the docking between the receiving mechanism 100 and the docking mechanism 200 of the patient support device 20.

[0073] In some specific embodiments, the receiving mechanism is provided with a receiving portion, and the receiving portion is used to match and dock with the guiding component 213 in the docking mechanism, so as to guide the docking between the docking mechanism and the receiving mechanism, thereby improving convenience.

[0074] In an exemplary embodiment, Figure 2 As shown, the receiving mechanism 100 is provided with a wind blocking structure, which includes an airflow blocking member 130 and a telescopic assembly 140, and the telescopic assembly 140 is connected to the airflow blocking member 130;

[0075] The airflow blocking member 130 is disposed in the first ventilation passage 111;

[0076] The telescopic assembly 140 is disposed at the receiving portion, and the telescopic assembly 140 is used to drive the airflow blocking member 130 to move so that the first ventilation channel 111 is opened.

[0077] The airflow blocking member 130 may be a component for blocking airflow, and may be arranged in cooperation with the first ventilation channel 111. For example, when airflow needs to flow to the gap of the docking surface, the airflow blocking member 130 may leave the first ventilation channel 111; when airflow does not need to flow to the gap of the docking surface, the airflow blocking member 130 may be used to block the first ventilation channel 111. The airflow blocking member 130 may be movably arranged to achieve airflow blocking or flow.

[0078] The telescopic assembly 140 may be a structure for driving the airflow blocking member 130 to move. For example, the airflow blocking member 130 may be a telescopic member 141 with a spring. The telescopic assembly 140 may be connected to the airflow blocking member 130 to drive the airflow blocking member 130 to move.

[0079] Exemplarily, the receiving mechanism 100 is provided with a wind-blocking structure, and the wind-blocking structure can be provided with an airflow blocking member 130. The airflow blocking member 130 can be arranged in conjunction with the first ventilation channel 111. The airflow blocking member 130 can be used to block the airflow flowing through the first ventilation channel 111, and can also block impurities on the docking surface from entering the first ventilation channel 111, thereby improving the reliability of the airflow conduction in the first ventilation channel 111, thereby improving the communication reliability of the medical imaging system.

[0080] The wind blocking structure may also be provided with a telescopic assembly 140, through which the movement of the airflow blocking member 130 may be driven, and one end of the telescopic assembly 140 may be fixedly connected to the airflow blocking member 130. When the telescopic assembly 140 is not docked, the airflow blocking member 130 may be in the airflow passage of the first ventilation channel 111 to keep the airflow passage of the first ventilation channel 111 blocked, and may prevent impurities on the docking surface from entering the interior of the object through the first ventilation channel 111. When the telescopic assembly 140 is docked, the telescopic assembly 140 may drive the airflow blocking member 130 to leave the airflow passage of the first ventilation channel 111, so that the airflow provided by the first fan 101 flows through the first ventilation channel 111 to the gap of the docking surface, and keep the docking surface clean, thereby improving the communication reliability of the medical imaging device 10.

[0081] In this embodiment, through the above-mentioned structure, it can be ensured that when the telescopic assembly is docked, the first fan provides airflow to the gap through the first ventilation channel, and the telescopic assembly can be prevented from being in a non-docked state, thereby keeping the inside of the docking structure of the medical imaging equipment clean, improving the flow guidance reliability of the first ventilation channel, and thus improving the communication reliability of the medical imaging equipment.

[0082] In an exemplary embodiment, Figure 2 As shown, the telescopic assembly 140 includes:

[0083] The telescopic member 141 is disposed in the receiving portion, one side of the telescopic member 141 is connected to the inner wall of the receiving portion, and the other side of the telescopic member 141 is fixedly connected to the airflow blocking member 130;

[0084] A connecting rod 142 , one end of which is connected to the other end of the telescopic member 141 , and the other end of the connecting rod 142 is located in the receiving portion and extends toward a direction close to the guide component 213 .

[0085] The telescopic member 141 may be any member capable of realizing a telescopic function. The telescopic member 141 may be a member composed of a plurality of springs. The fixed end of the telescopic member 141 may be used to fix the inner wall of the receiving portion. The movable end of the telescopic member 141 may be an end for movement, which may be used to drive the airflow blocking member 130 to move. The connecting rod 142 may be a connecting rod 142 for connecting an external force, which may be used to drive the telescopic member 141 to move.

[0086] Exemplarily, the telescopic assembly 140 may include a telescopic member 141 and a connecting rod 142, and both the telescopic member 141 and the connecting rod 142 may be arranged in the receiving portion. The fixed end of the telescopic member 141 may be connected to the inner wall of the receiving portion to keep the position of the telescopic member 141 fixed, and to ensure that the telescopic function of the telescopic member 141 can be realized. The movable end of the telescopic member 141 may fix the first end of the connecting rod 142, and when the telescopic assembly 140 is in docking, the second end of the connecting rod 142 receives the pressure provided by the patient support device 20 through the opening, so that the telescopic member 141 is compressed, and the movable end of the telescopic member 141 is driven to be compressed. The movable end of the telescopic member 141 may also be fixedly connected to the airflow blocking member 130, and when the movable end of the telescopic member 141 is driven to move, the airflow blocking member 130 may be driven to move, so as to drive the airflow blocking member 130 to leave the airflow path of the first ventilation channel 111.

[0087] In this embodiment, through the above-mentioned structure, when the telescopic components are docked, the patient support device can provide pressure to drive the airflow blocking member to leave the airflow path of the first ventilation channel, and the first fan can provide airflow for the gap of the docking surface, so as to keep the docking surface clean, thereby improving the communication reliability of the medical imaging equipment.

[0088] In an exemplary embodiment, the telescopic assembly 140 is docked as follows Figure 3 As shown, when the first housing 110 and the patient support device 20 are docked, the patient support device 20 provides pressure, and the second end of the connecting rod 142 receives the pressure provided by the patient support device 20 through the opening, so that the telescopic member 141 is compressed, and the airflow blocking member 130 is driven to leave the airflow path of the first ventilation channel 111. The first end of the first ventilation channel 111 is used to communicate with the air outlet of the first fan 101, and the second end of the first ventilation channel 111 is used to communicate with the outside through the gap. The first fan 101 provides airflow to the gap through the first ventilation channel 111 to keep the docking surface in a clean state, thereby improving the communication reliability of the medical imaging system.

[0089] In an exemplary embodiment, Figure 1 and Figure 2 As shown, a patient support device 20 is provided for connecting at least one medical imaging device 10 as described above, comprising:

[0090] A bed board 202 and a base 206 supporting the bed board 202;

[0091] The base 206 is provided with a docking mechanism 200;

[0092] The docking mechanism 200 is provided with a second ventilation channel 211;

[0093] When the docking mechanism 200 and the receiving mechanism 100 of the medical imaging device 10 are in a docking state, the second ventilation channel 211 and the first ventilation channel 111 are communicated with each other.

[0094] The docking mechanism 200 can be a mechanism for the patient support device 20 to dock with the medical imaging device 10, and the docking mechanism 200 can dock with the receiving mechanism 100. The second ventilation channel 211 can be a pipeline for conducting airflow, or can be used for internal heat dissipation of the patient support device 20.

[0095] For example, the patient support device 20 may include a bed plate 202 and a base 206 for supporting the bed plate 202. The base 206 may include: Figure 2 The docking mechanism 200 shown. The docking mechanism 200 may be provided with a second ventilation channel 211. When the docking mechanism 200 and the receiving mechanism 100 of the medical imaging device 10 are in a docking state, the medical imaging device 10 may perform medical imaging communication with the patient support device 20, and at the same time, the second ventilation channel 211 may be turned on and communicated with the first ventilation channel 111 to dissipate heat for the patient support device 20 through the second ventilation channel 211.

[0096] In some specific embodiments, a bed plate and a base supporting the bed plate are provided; the base is provided with a docking mechanism; the docking mechanism is provided with a second ventilation channel; when the docking mechanism and the receiving mechanism of the medical imaging device are in a docking state, the second ventilation channel is opened. In this way, through the above structure, heat dissipation can be provided for the patient support device through the second ventilation channel, and the docking surface of the patient support device and / or the interior of the patient support device can be kept in a clean state through the second ventilation channel, thereby improving the communication reliability between the patient support device and the medical imaging device during the medical imaging process.

The second end of the second ventilation channel 211 is connected to the air outlet of the second fan 201 and / or to the outside world. When the second end of the second ventilation channel 211 is connected to the air outlet of the second fan 201, the airflow provided by the second fan 201 can be transmitted to the gap of the docking surface, and the impurities such as dust, liquid, foreign matter, etc. remaining on the docking surface can be blown out through the gap by the airflow; when the second end of the second ventilation channel 211 is connected to the outside world, the second ventilation channel 211 can transmit the airflow provided by the first fan 101, and can, through the second ventilation channel 211, blow out the impurities such as dust, liquid, foreign matter, etc. remaining on the docking surface through the outside world connected to the second end of the second ventilation channel 211, thereby improving the communication reliability of the medical imaging system.

The first cable 120 may be used to connect with the cable of the patient support device 20 to achieve communication between the medical imaging device 10 and the patient support device 20. The communication here may refer to the communication between the sending and receiving of radio frequency signals. The first cable 120 may also be used for communication between the medical imaging device 10 and the host computer 30, so that the patient support device 20 and the host computer 30 can be communicated through the first cable 120. The docking surface may be a docking surface between the medical imaging device 10 and the patient support device 20, for example, it may be a docking surface between the housing of the medical imaging device 10 and the housing of the patient support device 20. In the case of docking or coupling, the housing of the medical imaging device 10 and the housing of the patient support device 20 are close to each other to achieve the connection between the first cable 120 of the medical imaging device 10 and the cable of the patient support device 20. The gap may be a gap formed at the docking surface by the first end of the first cable 120 protruding. The first cable 120 may be an electrical cable, and the first end of the first cable 120 may be an electrical interface end; the electrical interface may be used to transmit power, synchronization signals, self-loop test signals, local radio frequency transmission signals, a hospital bed motor control bus, and the like.

[0125] Exemplarily, the receiving mechanism 100 of the medical imaging device 10 may be provided with a first shell 110, and the first shell 110 may be provided with a first accommodating cavity 112. A first cable 120 may be provided in the first accommodating cavity 112, and the first cable 120 may be used to connect the patient support device 20 and the host computer 30, and the medical imaging device 10, the patient support device 20 and the host computer 30 may be communicated with each other in at least two combinations through the first cable 120. The first cable 120 may be protrudingly provided at the docking surface between the first shell 110 and the patient support device 20, so that a gap is formed when the first shell 110 and the patient support device 20 are docked, and the gap may be communicated with the outside world, and further, the first ventilation channel 111 may be communicated with the outside world through the gap. In this way, communication between at least two combinations of the medical imaging equipment 10, the patient support device 20 and the host computer 30 can be achieved through the first cable 120, and the fan and the first ventilation channel 111 can be used to keep the docking surface clean, remove dust, liquid, foreign matter and other impurities on the docking surface, and improve communication reliability.

[0126] Optionally, the first cable 120 can be arranged in cooperation with the cable of the patient support device 20 at the interface between the first shell 110 and the patient support device 20 to achieve the connection between the cables. The first cable 120 is protrudingly arranged at the interface between the first shell 110 and the patient support device 20, and can be arranged in a form that does not block the air outlet of the first ventilation channel 111, so as to prevent the first ventilation channel 111 from being unable to conduct the airflow to the interface between the first shell 110 and the patient support device 20.

In this way, through the above structure, when the first housing is docked with the patient support device 20, the pressure provided by the detection object carrier device drives the airflow blocking member 130 to leave the airflow path of the first ventilation channel 111, and the first fan 101 can provide airflow for the gap of the docking surface, so that the clean state of the docking surface can be maintained, thereby improving the communication reliability of the medical imaging system. At the same time, the receiving opening provided in the second accommodating cavity can realize the guiding function in the docking process, so that the docking of the first housing and the patient support device 20 can be more convenient.

[0129] In an exemplary embodiment, Figure 4 As shown, the length direction of the first end of the first cable 120 is parallel to the airflow direction provided by the first ventilation channel 111 at the mating surface.

[0141] An electronic component assembly module 103 may also be provided on the scanner unit 102. The electronic component assembly module may include a power supply. The power supply may be connected to the first fan 101 through a first end of the electronic component assembly module 103, so as to supply power to the first fan 101 when the medical imaging device 10 and the patient support device 20 are docked.

[0142] The second end of the electronic component assembly module 103 can be connected to the second end of the first cable 120, and the first end of the first cable 120 can be connected to the patient support device 20 to achieve communication between the medical imaging device 10 and the patient support device 20. The third end of the electronic component assembly module 103 can be used to connect to the host computer 30 to achieve communication between the medical imaging device 10 and the host computer 30.

[0143] In this way, through the above structure, the docking surface of the receiving mechanism 100 of the medical imaging device 10 can be kept in a clean state, thereby improving the communication reliability of the medical imaging device 10 during the medical imaging process.

[0144] In an exemplary embodiment, Figure 1 As shown, the medical imaging device 10 further includes a connecting pipeline 104 and a heat dissipation pipeline 105 .

[0145] The connecting pipe 104 is connected to the air outlet of the first fan 101 and the first end of the first ventilation channel 111 respectively;

[0146] The heat dissipation pipeline 105 is disposed on the connecting pipeline 104 , and the air outlet opening of the heat dissipation pipeline 105 faces the electronic component assembly module 103 , so that the first fan 101 dissipates heat for the electronic component assembly module 103 through the heat dissipation pipeline 105 .

[0147] The connecting pipeline 104 may be a pipeline for connecting the connecting pipeline 104 and the first ventilation channel 111. The heat dissipation pipeline 105 may be a pipeline for heat dissipation.

[0148] Exemplarily, the medical imaging device 10 may also be provided with a connecting pipe 104 for connecting the connecting pipe 104 and the first ventilation channel 111, and the connecting pipe 104 respectively connects the air outlet of the first fan 101 and the first ventilation channel 111.

[0149] The medical imaging device 10 may also be provided with a heat dissipation pipeline 105, which may be provided at a position on the connection pipeline 104 corresponding to the electronic component assembly module 103, so that the air outlet receiving opening of the heat dissipation pipeline 105 may be oriented toward the electronic component assembly module 103, and the first fan 101 may dissipate heat for the electronic component assembly module 103 through the heat dissipation pipeline 105. The heat dissipation pipeline 105 may be provided with a switch, and when the medical imaging device 10 is docked with the patient support device 20, the conduction of the heat dissipation pipeline 105 may be controlled by the switch, so that the first fan 101 dissipates heat for the electronic component assembly module 103 through the heat dissipation pipeline 105.

[0150] Optionally, the first fan 101 can be a fan for heat dissipation of the receiver. In a relatively high-field medical imaging system that is more susceptible to the spillover magnetic field, it can be set outside the scanning room, such as in an equipment room. In this case, the electronic component assembly module 103 located in the scanner unit 102 is interconnected with the first fan 101 located in the equipment room via a long control cable. The switch of the first fan 101 and the control of the air volume can come from the electronic component assembly module 103.

[0151] If the electronic component assembly module 103 is completely decoupled from the first fan 101 and has an independent cooling method, the first fan 101 is turned on after the medical imaging device 10 and the patient support device 20 are identified to be docked, and the first fan 101 is turned off after the two are identified to be detached, and the upper opening of the heat dissipation pipeline 105 is closed. At this time, the receiving mechanism 100 of the medical imaging device 10 does not contain a transmission mechanical switch.

After identifying that the medical imaging device 10 and the patient support device 20 are docked, the receiver main body module inside the electronic component assembly module 103 is completely powered off, and the cooling air is guided to the surface of the docking mechanism 200 of the patient support device 20 by a mechanical switch in the receiving mechanism 100 of the medical imaging device 10 for air cooling and heat dissipation. After identifying that the medical imaging device 10 and the patient support device 20 are separated, the receiver main body module inside the electronic component assembly module 103 is powered on, and the cooling air is isolated from the docking mechanism 200 of the patient support device 20 by a mechanical switch in the receiving mechanism 100 of the medical imaging device 10, so that the cooling air is guided to the inside of the electronic component assembly module 103 to cool the receiver main body module. At this time, one implementation method of the mechanical switch in the receiving mechanism 100 of the medical imaging device 10 is as follows: Figure 2 A spring plus piston projection mechanism 140 is shown.

The second end of the second ventilation channel 211 is connected to the air outlet of the second fan 201 and / or to the outside world. When the second end of the second ventilation channel 211 is connected to the air outlet of the second fan 201, the airflow provided by the second fan 201 can be transmitted to the gap of the docking surface, and the impurities such as dust, liquid, foreign matter, etc. remaining on the docking surface can be blown out through the gap by the airflow; when the second end of the second ventilation channel 211 is connected to the outside world, the second ventilation channel 211 can transmit the airflow provided by the first fan 101, and can, through the second ventilation channel 211, blow out the impurities such as dust, liquid, foreign matter, etc. remaining on the docking surface through the outside world connected to the second end of the second ventilation channel 211, thereby improving the communication reliability of the medical imaging system.

[0166] Optionally, the second cable 220 can be arranged in cooperation with the first cable 120 at the interface between the second housing 210 and the first housing 110 to achieve the connection between the cables. The second cable 220 is arranged protrudingly at the interface between the second housing 210 and the first housing 110, and can be arranged in a form that does not block the air outlet of the first ventilation channel 111 and / or the second ventilation channel 211, so as to prevent the first ventilation channel 111 and / or the second ventilation channel 211 from being unable to conduct the airflow to the interface between the first housing 110 and the second housing 210.

[0167] In some specific embodiments, a second shell is provided, and the second shell is formed with a second ventilation channel and a third accommodating chamber; a second cable is provided in the third accommodating chamber, and a first end of the second cable is used to connect to a magnetic signal receiving coil of a patient support device; and when a receiving mechanism of the medical imaging device and a docking mechanism of the patient support device are docked, a second end of the second cable is connected to a first end of the first cable, and a first end of the second ventilation channel is connected to a second end of the first ventilation channel 111, and a second end of the second ventilation channel is used to connect to an air outlet of a second fan of the patient support device and / or to the outside world. In this way, through the above structure, the first fan and / or the second fan can provide airflow for the second ventilation channel, so that the docking surface and / or the interior of the docking mechanism of the patient support device can be kept in a clean state, thereby improving the communication reliability of the medical imaging system.

[0168] In an exemplary embodiment, the receiving mechanism 100 of the medical imaging device 10 and the docking mechanism 200 of the patient support device 20 are docked as follows: Figure 3 As shown. When the medical imaging device 10 and the patient support device 20 are docked, the guide component 213 provides pressure, and the second end of the connecting rod 142 receives the pressure provided by the guide component 213 through the receiving opening, so that the telescopic member 141 is compressed, and the airflow blocking member 130 is driven to leave the airflow path of the first ventilation channel 111. The first end of the first ventilation channel 111 is used to communicate with the air outlet of the first fan 101, and the second end of the first ventilation channel 111 is used to communicate with the outside through the gap, and the second end of the first ventilation channel 111 is connected to the first end of the second ventilation channel 211. The first fan 101 can provide airflow to the gap through the first ventilation channel 111, and the second fan 201 can provide airflow through the first ventilation channel 111 to keep the docking surface in a clean state, thereby improving the communication reliability of the medical imaging system.

[0169] Alternatively, if Figure 3As shown, the docking mechanism 200 of the patient support device 20 can be provided with a second shell 210, and the second shell 210 can be provided with a third accommodating cavity 212 and a second ventilation channel 211. The second ventilation channel 211 can be respectively connected to the air outlet of the second fan 201 and the gap of the docking surface, and the gap can be connected to the outside. For example, the first end of the second ventilation channel 211 can be arranged to be connected to the second end of the first ventilation channel 111, or can be connected to the outside world through a gap. The second end of the second ventilation channel 211 is connected to the air outlet of the second fan 201 and / or to the outside world. When the second end of the second ventilation channel 211 is connected to the air outlet of the second fan 201, the airflow provided by the second fan 201 can be transmitted to the gap of the docking surface, and the impurities such as dust, liquid, foreign matter, etc. remaining on the docking surface can be blown out through the gap by the airflow; when the second end of the second ventilation channel 211 is connected to the outside world, the second ventilation channel 211 can transmit the airflow provided by the first fan 101, and can, through the second ventilation channel 211, blow out the impurities such as dust, liquid, foreign matter, etc. remaining on the docking surface through the outside world connected to the second end of the second ventilation channel 211, thereby improving the communication reliability of the medical imaging system.

[0170] The third accommodating cavity 212 may be provided with a second cable 220, the first end of the second cable 220 is used to connect the magnetic signal receiving coil of the patient support device 20, and the second end of the second cable 220 is used to connect the first end of the first cable 120, and the second cable 220 may be protrudingly arranged at the docking surface between the second shell 210 and the first shell 110, so that a gap is formed when the first shell 110 and the second shell 210 are docked, and the gap can be communicated with the outside world, and further, the second ventilation channel 211 can be communicated with the outside world through the gap. In this way, the second cable 220 can be used to realize communication between at least two combinations of the medical imaging device 10, the patient support device 20 and the host computer, and the fan and the second ventilation channel 211 can be used to keep the docking surface clean, remove dust, liquid, foreign matter and other impurities on the docking surface, and improve communication reliability.

[0171] If the receiving mechanism 100 of the medical imaging device 10 includes the first wireless transmission circuit 150 , the docking mechanism 200 of the patient support device 20 may be provided with a second wireless transmission circuit 230 , and the second wireless transmission circuit 230 may be electromagnetically coupled to the first wireless transmission circuit 150 .

[0172] In an exemplary embodiment, Figure 5 As shown, the docking mechanism 200 of the patient support device 20 further includes:

[0173] The second wireless transmission circuit 230 is embedded in the guide component 213 .

[0174] The second wireless transmission circuit 230 may be a contactless communication circuit that communicates or couples via a short-range wireless magnetic field.

[0175] Exemplarily, the docking mechanism 200 of the patient support device 20 can be provided with a second wireless transmission circuit 230, and the second wireless transmission circuit 230 can be provided in the guide component 213. The electromagnetic coupling connection between the second wireless transmission circuit 230 and the first wireless transmission circuit 150 can be achieved through the cooperation between the guide component 213 and the first shell 110.

[0176] Thus, through the above structure, the guidance, heat dissipation and signal path can be integrated into one, which can reduce the weight of the patient support device 20 and make it easier to move.

[0177] In an exemplary embodiment, Figure 5 As shown, the first wireless transmission circuit 150 can be arranged at a position corresponding to the guide component 213 of the patient support device 20, so as to realize electromagnetic coupling connection between the first wireless transmission circuit 150 and the second wireless transmission circuit 230. The position corresponding to the guide component 213 can be the corresponding position after the guide component 213 enters the receiving opening of the receiving mechanism 100 of the medical imaging device 10 when the medical imaging device 10 is docked with the patient support device 20.

[0178] In an exemplary embodiment, Figure 2 In the docking form, the plane layout of the docking surface Figure 4 As shown, the length direction of the first end of the first cable 120 protruding from the mating surface is set to be parallel to the airflow direction, reducing the obstruction of the airflow by the first end of the first cable 120 protruding, and the plane layout ensures that the electrical interface does not block the wind path. Figure 5 In the docking form, the plane layout of the docking surface is as follows Figure 6 As shown. Figure 4 , 6 As shown, the planar layout of the docking surface includes a coupling connection position 410 of the first wireless transmission circuit and the second wireless transmission circuit, and may also include a coupling connection position 420 of the backup wireless transmission circuit of the medical imaging device 10 and the patient support device 20. In this way, the above structure can reduce the obstruction of the airflow in the gap, improve the cleanliness of the docking surface, and further improve the communication reliability.

[0179] In an exemplary embodiment, Figure 1 As shown, the medical imaging system further includes:

[0180] Host computer 30;

[0181] Exemplarily, the host computer 30 can be used to reconstruct images of data from the front end and transmit control instructions to the front end, and is generally located in the remote equipment room. The medical imaging device 10 can be provided with a scanner unit 102, which can be a magnetic scanner unit 102 or a device room scanner unit 102. The device room scanner unit 102 can be located in the equipment room and carry electronic components in the form of an electronic chassis cabinet. The electronic components can include electronic components such as radio frequency transceivers, fans, sequence controllers, and cables interconnecting the various components. The patient support device 20 can be movable and can be plugged in and out along the Z-axis direction on the medical imaging device 10 to carry the patient to be scanned. After being connected to the medical imaging device 10, the bed board 202 on it can be controlled by the scanning workflow to carry the patient up and down and move along the Z-axis, and the patient is sent into the aperture of the medical imaging device 10 for scanning, and can be moved out of the aperture when the scanning is completed.

[0182] The medical imaging device 10 and the patient support device 20 are connected to each other through the receiving mechanism 100 of the medical imaging device 10 and the docking mechanism 200 of the patient support device 20, and the docking surfaces of the two are located in the XY plane in the coordinate system. The two are fixed by a guide structure to ensure a secure docking. The user operates the handle and pedal of the patient support device 20 to coordinately complete the docking and detachment of the movable patient support device 20 relative to the fixed medical imaging device 10, that is, the plug-in operation. The more electrical connection pins there are between the receiving mechanism 100 of the medical imaging device 10 and the docking mechanism 200 of the patient support device 20, the greater the required plug-in force, which can minimize the number of electrical connection pins. For some safety risk-related signals and high-power energy transmission paths that require hard links, they can still be interconnected through traditional contact electrical connectors.

[0183] Through the above structure, the docking mechanism 200 between the medical imaging device 10 and the patient support device 20 in the medical imaging system can be kept in a clean state, thereby improving the communication reliability of the medical imaging system during the magnetic resonance imaging process.

[0184] In an exemplary embodiment, Figure 1 As shown, the medical imaging device 10 includes an electronic component assembly module 103, a first fan 101, a heat dissipation pipeline 105, a receiving mechanism 100 of the medical imaging device 10, and interconnecting cables.

[0185] The patient support device 20 includes a bed board 202 on the patient support device 20, a second fan 201, a cable bundle 203, a handle 204, a pedal 205, a docking mechanism 200 of the patient support device 20, and interconnected cables. The bed board 202 on the patient support device 20 can be used to control the patient to enter and exit the magnet aperture to complete the scanning workflow. Generally, it includes multiple coil sockets, and the multiple coil sockets correspond to their own mixed cables, which are used to transmit the radio frequency from the coil and the control signal from the back-end software. The multiple mixed cables are finally aggregated into a unified cable bundle and connected to the receiving mechanism 100 of the medical imaging device 10 along the drag chain connected to the bed board 202 on the patient support device 20. The second fan 201 can be a backup fan reserved in the patient support device 20, which can be used to cool the receiver in the docking mechanism 200 of the patient support device 20 in the event of failure of the first fan 101. When used, the switch of the second ventilation channel 211 can be manually turned on, and it can be kept closed at other times.

[0186] In an exemplary embodiment, Figure 2As shown, it is an XZ plane structure diagram of the receiving mechanism 100 of the medical imaging device 10 and the docking mechanism 200 of the patient support device 20. The transmission structure of the telescopic component 140 and the airflow blocking member 130 can be used to control the conduction of the air path. After the docking is completed, the conduction is turned on. After the detachment, the telescopic member 141 automatically rebounds and the air path is closed. The docking mechanism 200 of the patient support device 20 can use the second fan 201 to supply air when the manual switch MS2 is turned on. After the patient support device 200 enters the docking mechanism 200 of the patient support device 20 along the bed drag chain, it is first wound and docked with the second wireless transmission circuit 230. The second wireless transmission circuit 230 can be provided with a receiver, and a plurality of mixed connectors are provided at the front end for docking with various mixed cables in the patient support device 200, which is responsible for receiving radio frequency signals for processing and coil control, that is, converting and transmitting the control instructions from the host computer 30 to the coil, and finally processing the radio frequency signal from the coil into a digital baseband or intermediate frequency signal. The second wireless transmission circuit 230 can be integrally arranged in the frame of the docking mechanism 200 of the patient support device 20 and close to the heat dissipation substrate (e.g., aluminum substrate) at the bottom. Structurally, the heat dissipation surface can extend from the substrate to the side of the docking mechanism 200 of the patient support device 20 where the docking surface is located. The docking plane is between the receiving mechanism 100 of the medical imaging device 10 and the docking mechanism 200 of the patient support device 20, and a gap for the heat dissipation wind to flow through will be reserved after the docking is completed. The docking method between the two can include a small number of electrical plug-in interfaces and contactless communication interfaces, and can include a guide component 213 (guide pin) for guiding and driving the telescopic component 140. The electrical interface between the two can be used to transmit power, synchronization signals, self-loop test signals, local radio frequency transmission signals, bed motor control buses, etc. These signals all come from the electronic component assembly module 103. Some key safety signals, such as synchronization signals, can be set up as dual backups. The contactless communication interface between the two can be realized by short-range radio magnetic field communication / coupling, wireless optical transmission, etc. The first wireless transmission circuit 150 in the receiving mechanism 100 of the medical imaging device 10 can be responsible for converting wireless signals into electrical signals or optical signals and connecting them to the electronic component assembly module 103 via cables. Similarly, the docking mechanism 200 of the patient support device 20 can also include a similar wireless-to-wired module.

[0187] Optionally, another docking form of the receiving mechanism 100 of the medical imaging device 10 and the docking mechanism 200 of the patient support device 20 is as follows: Figure 5 As shown, Figure 5 This is a ZY plane structure diagram of another docking form.

[0188] Optionally, the bottom connection structure 200 of the first wireless transmission circuit 150 and the second wireless transmission circuit 230 is as follows: Figure 7 shown.

[0189] The signal processing and coil control link body in the second wireless transmission circuit 230 is a cable 233, which is connected to a mixed interface including all RF and DC control channels. The first wireless conversion module 151 is a wireless to optical or electrical module, which can be electrically coupled to the second wireless conversion module 231. In order to maximize reliability, a dual backup method can be adopted, and a first wireless backup module 152 is set, which can be electrically coupled to the second wireless backup module 232 to ensure that once an extreme situation occurs and one of the wireless paths is blocked, another path can be switched.

[0190] In an exemplary embodiment, the internal structure of the electronic component assembly module 103 is as follows: Figure 8 As shown, a receiver body 1031 is included, and the functions completed can be exactly the same as those of the first wireless transmission circuit 150, which is used to adapt to the situation of including a non-movable patient support device 20. For the movable patient support device 20, it switches to any one of the links with normal connectivity in the communication link using the dual backup mode, and the communication link in the dual backup mode includes a third wireless conversion module 1032 and a third wireless backup module 1033. The switching operation is completed by a multi-way switch 1034, and the multi-way switch 1034 is connected to the communication connection module 1035. When the system recognizes an immovable fixed patient support device 20, it switches to the receiver body 1031. When the system is upgraded to a movable patient support device 20 and recognizes it, it switches to one of the following dual backup communication links. After passing through the multi-way switch, the data is further processed, packaged, and protocol encapsulated, and finally transmitted to the host computer 30. The path for issuing control instructions is opposite to the direction of data transmission. The electronic component assembly module 103 may also be provided with a heat dissipation pipeline 105 for heat dissipation. The heat dissipation pipeline 105 may be connected to the air outlet of the first fan 101 , and the air outlet of the heat dissipation pipeline 105 is arranged toward the electronic component.

[0191] In some specific embodiments, the embodiments provided above in the present application can use a close-range non-contact wireless interconnection method to replace most of the electrical interconnection pins, greatly improving reliability, reducing plug-in force, and improving operation convenience. The driving capacity requirements of the motor and battery in the electric power assist system in the patient support device are also reduced, and power consumption, volume and cost can also be reduced. The receiver can be moved forward to the base of the pluggable patient support device, and the data of a large number of radio frequency channels can be merged into a very small wireless interconnection data path. At the same time, the reliability of data transmission is further improved by using a dual backup method. The receiver is attached to the base of the pluggable patient support device for auxiliary heat dissipation, and the base material can be a metal aluminum substrate. In this way, the metal skeleton of the entire patient support device can assist in heat dissipation. The near-field interconnection interface is coplanar with the heat dissipation structure of the receiver. By triggering the fan supply mechanism after docking, dust, foreign matter, rust, and even liquid impurities that may be attached to the near-field interface can be cleaned in real time while the receiver is cooled, so as to avoid the hidden danger of impurities blocking due to the complex environment, and at the same time, the interface is kept dry to avoid rust, further improving communication reliability. The overall structural form of the docking mechanism can be made into a guide device, which can be made into a guide, auxiliary heat dissipation, and receiver functions. At the same time, it is relatively convenient to disassemble and install, ensuring good maintainability. When the fixed patient support device is upgraded to a pluggable mobile patient support device, the update can be completed at the minimum cost without replacing any electronic components and cables on the magnet rack side. In the event of a near-field communication failure, the mixed cable that transmits the analog radio frequency signal internally can be unfolded, extended to the magnet rack side and connected to another set of receivers, and temporarily used as a fixed patient support device, so as not to affect the user's clinical scanning process. The receiver has a large power consumption, basically at the level of several hundred watts. The water-cooled quick-plug connector has the risk of leakage, and it is impossible to guarantee the tens of thousands of reliable plug-ins and unplugs of the water-cooled quick-plug connector. Therefore, water cooling is not applicable. Air cooling can be adopted at the base of the patient support device. The cooling source comes from the first fan and / or the second fan. The fan can be placed on the side of the magnet rack, or on the filter board away from the magnet or even in the equipment room, and the wind is guided to the vicinity of the receiver through a long air duct. Placing the fan inside the patient support device as a backup for the external fan is also a temporary backup option for abnormal situations, further improving system reliability and robustness and avoiding affecting user use. By identifying whether the patient support device is docked: the fan is powered on and off or the air volume level is controlled to reduce power consumption; the main circuit of the receiver on the magnet rack side is powered on and off to reduce power consumption.
