Description
Technical Field
[0001] The present disclosure relates to the technical field of nuclear magnetic resonance, for example, to a radio frequency receiving device. Background Art
[0002] In a magnetic resonance imaging (MRI) system, a radio frequency receiving device is responsible for receiving magnetic resonance signals and performing a series of processing steps on them, including tuning / detuning, amplification, and filtering, etc., to ensure the quality and stability of the signals. According to the IEC 60601-1 standard, the surface temperature of the radio frequency receiving device shall not exceed 41 °C under extreme environments to ensure patient safety.
[0003] In the related art, the radio frequency receiving device includes a protective outer layer and electronic components for processing magnetic resonance signals, and the electronic components are encapsulated within the protective outer layer. The electronic components include heat-generating components. To prevent these heat-generating components from causing the surface temperature of the radio frequency receiving device to be too high, the protective outer layer is usually designed to be relatively thick, thereby forming a large air gap around the heat-generating elements. This design can effectively delay the heat conduction to the surface of the radio frequency receiving device and prevent the local temperature on the surface of the radio frequency receiving device from exceeding 41 °C due to overheating of the heat-generating elements.
[0004] For the radio frequency receiving device in the related art, although it can prevent the local temperature on its surface from exceeding 41 °C, the heat generated by the heat-generating components in the electronic components will accumulate inside the radio frequency receiving device for a long time and cannot be released in time, which may affect the performance of the radio frequency receiving device.
[0005] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.
[0024] Unless otherwise stated, the term "multiple" means two or more.
[0025] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.
[0026] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.
[0027] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.
[0028] In a magnetic resonance imaging (MRI) system, the radio frequency (RF) receiver is responsible for receiving MRI signals and performing a series of processing steps, including tuning / detuning, amplification, and filtering, to ensure signal quality and stability. According to the IEC 60601-1 standard, the surface temperature of the RF receiver must not exceed 41°C in extreme environments to ensure patient safety.
[0029] In related technologies, radio frequency (RF) receivers include a protective outer layer and electronic components for processing magnetic resonance signals, with the electronic components encapsulated within the protective outer layer. Specifically, the protective outer layer comprises a rigid protective box and a flexible protective sheath. The electronic components are housed inside the protective box, and the protective box, along with the electronic components, is encapsulated within the protective sheath. The signal processing unit contains heat-generating components. To prevent these heat-generating components from causing excessively high surface temperatures on the RF receiver, the protective box is typically designed to be thick, providing ample internal space and creating large air gaps around the heat-generating components. This design effectively delays heat conduction to the surface of the RF receiver, preventing localized surface temperatures from exceeding 41°C due to overheating of the heat-generating components.
[0030] Although the radio frequency receiving device of the related technology can avoid the local temperature of its surface from exceeding 41°C, the heat generated by the heat-generating components in the electronic components will accumulate inside the radio frequency receiving device for a long time and cannot be released in time, which may affect the performance of the radio frequency receiving device.
[0031] Furthermore, the related RF receivers also include notch filters, which also generate heat. However, the related RF receivers cannot effectively block the heat generated by the notch filters, and there is a risk that the local temperature of the RF receiver may exceed 41°C due to overheating of the heating elements.
[0032] This disclosure provides a radio frequency receiving device, combined with... Figure 1 As shown, the radio frequency receiving device includes an electronic component 100, a thermally conductive material layer 200, and a protective outer casing 300 disposed outside the electronic component 100 and the thermally conductive material layer 200. The electronic component 100 includes a heating element, and the thermally conductive material layer 200 covers the heating element. Here, the heating element may include a signal processing unit 1 and a notch filter 2, and the thermally conductive material layer 200 covers each of the signal processing unit 1 and the notch filter 2, wherein, for example... Figure 2 As shown, the signal processing unit 1 includes a circuit board 11 and a plurality of signal processing elements 12 disposed on the circuit board 11. It should be noted that the covering may completely cover the surface of the heat-generating component, or it may cover opposite sides of the heat-generating component; the degree of covering is related to the structure of the electronic component and the material properties of the thermally conductive material layer.
[0033] In this embodiment, the electronic component 100 further includes cables 3. The signal processing unit 1, the notch filter 2, and the cables 3 correspond one-to-one. The signal processing unit 1 is connected to the corresponding cable 3, and the notch filter 22 is fitted onto the corresponding cable 3. The number of signal processing units 1, notch filters 2, and cables 3 can be determined according to actual design needs. For example, the number of signal processing units 1, notch filters 2, and cables 3 can all be 12, forming one signal transmission group consisting of one signal processing unit 1, one notch filter 2, and one cable 3. In one signal transmission group, the signal processing unit 1 is connected to the cable 3, and the notch filter 2 is fitted onto the cable 3. Three signal transmission groups form a column, and the column of signal transmission groups is arranged along a first direction. In a column of signal transmission groups, the cable 3 of the rear signal transmission group passes through the notch filter 2 of its own group, as well as through the notch filters 2 of each signal transmission group located in front of that group.
[0034] Figure 3 A cross-sectional schematic diagram of the radio frequency receiving device near a signal processing unit 11 is shown. Figure 4 A schematic cross-sectional view of the radio frequency receiving device near a notch filter 2 is shown. Figure 1 , Figure 3 and Figure 4 As shown, a thermally conductive material layer 200 encloses the signal processing unit 1, the notch filter 2, and a portion of the cable 3. (As shown...) Figure 3 and Figure 4As shown, the thermally conductive material layer 200 can be divided into upper and lower sides. The two thermally conductive material layers 200 are respectively attached to two opposite sides of the signal processing unit 1 and two opposite sides of the notch filter 2. Of course, the thermally conductive material layer 200 can also be a single unit, completely enclosing the signal processing unit 1 and the notch filter 2.
[0035] Because the heat-generating component in the electronic component 100 is encased in the thermally conductive material layer 200, the heat generated by the heat-generating component can be rapidly conducted to the surrounding area by the thermally conductive material layer 200, effectively reducing the temperature at the location of the heat-generating component. This helps prevent the local temperature of the RF receiver from exceeding 41°C due to overheating. Furthermore, by rapidly conducting heat, the thermally conductive material layer 200 prevents heat accumulation at the location of the heat-generating component, enabling the RF receiver to operate within an ideal temperature range and contributing to its optimal performance.
[0036] Specifically, the heat generated by the signal processing unit 1 and the notch filter 2 can be rapidly conducted to the surrounding area by the thermally conductive material layer 200, effectively reducing the temperature at the location of the signal processing unit 1 and the notch filter 2. This helps prevent the local temperature of the RF receiving device from exceeding 41°C due to overheating. Furthermore, by rapidly conducting heat, the thermally conductive material layer 200 prevents heat accumulation at the location of the signal processing unit 1 and the notch filter 2, allowing the RF receiving device to operate within an ideal temperature range and contributing to its optimal performance.
[0037] In some embodiments, as described above, the signal processing unit 1 in the heating component includes a circuit board 11 and a plurality of signal processing elements 12 disposed on the circuit board 11. Here, the plurality of signal processing elements 12 include a plurality of heating elements, which are in contact with the thermally conductive material layer 200. Of course, the plurality of signal processing elements 12 may also include non-heating elements. The plurality of signal processing elements 12 on the circuit board 11 include elements in the detuning tuning assembly, elements in the notch filter circuit, elements in the matching circuit, amplifiers, etc. Among them, the elements in the detuning tuning assembly, the elements in the notch filter circuit, and the amplifier are all heating elements, while the elements in the matching circuit are non-heating elements. The detuning tuning assembly includes an inductor, a capacitor, and a diode. When the diode is conducting, its circuit is equivalent to a high impedance at the radio frequency, which hinders the flow of radio frequency current in the receiving unit of the radio frequency receiving device and prevents radio frequency power coupling into the radio frequency receiving device. The notch filter circuit is composed of an inductor and a capacitor connected in parallel. It resonates at the radio frequency and is equivalent to a high impedance. Its function is to eliminate the common-mode effect.
[0038] In some embodiments, the signal processing unit 1 is configured with an antenna 4, which is connected to a detuning assembly on a circuit board 11 in the signal processing unit 1. The antenna 4 is a flexible loop, where the signal processing element 12 for processing signals is integrated into the circuit board 11, which occupies a smaller area, while no other elements are placed on the antenna 4, which occupies a larger area, thereby enhancing the flexibility of the antenna 4 and improving the overall flexibility of the radio frequency receiving device.
[0039] In some embodiments, multiple heating elements are arranged discretely, which can avoid excessive heat concentration due to the heating elements being too close together, thus affecting the heat dissipation speed.
[0040] In some embodiments, multiple heating elements are distributed on the upper and lower surfaces of the circuit board 11. Distributing the heating elements across the upper and lower surfaces of the circuit board 11 increases the overall distance between the heating elements, preventing excessive heat concentration caused by the heating elements being too close together, which would affect the heat dissipation speed. In addition, this arrangement of heating elements can make full use of the upper and lower thermally conductive material layers 200 to conduct heat, thereby improving heat dissipation efficiency.
[0041] In some embodiments, the electronic component 100 further includes a protective housing 5, which covers the outside of the heat-generating component, with a thermally conductive material layer 200 located between the protective housing and the heat-generating component. Specifically, the protective housing 5 covers the circuit board 11 and a plurality of signal processing elements 12 thereon. The protective housing 5 is made of a non-conductive material; for example, it may be made of plastic. The wall thickness of the protective housing 5 can be determined according to actual design requirements; for example, the wall thickness of the protective housing 55 may be millimeters.
[0042] The protective box 5 can be a shell formed using a one-piece molding process, or it can be composed of multiple parts. Taking a protective box 5 composed of multiple parts as an example... Figure 5 The protective box 5 is designed for use in an exploded state. The protective box 5 includes an upper cover 51 and a bottom shell 52, with the upper cover 51 fastened to the bottom shell 52 to form a complete protective box 5. The circuit board 11 and its multiple signal processing components 12 are located inside the protective box 5 to prevent damage to the signal processing components 12. The protective box 5 has a cutout area 53 through which a portion of the thermally conductive material layer 200 passes, encasing the circuit board 11 and signal processing components 12 within the protective box 5.
[0043] In some embodiments, the height of the signal processing unit 1 is between 6 mm and 16 mm. Limiting the height of the signal processing element 12 helps to reduce the overall thickness of the radio frequency receiving device.
[0044] In some embodiments, the height of the signal processing element 12 on the circuit board 11 in the signal processing unit 1 is between 2.5 mm and 4 mm. Optionally, the maximum height of the signal processing element 12 located on the upper surface of the circuit board 11 does not exceed 4 mm, and the maximum height of the signal processing element 12 located on the lower surface of the circuit board 11 does not exceed 2 mm.
[0045] In some embodiments, as described above, the heat-generating component includes a notch filter 2. The notch filter 2 includes an LC oscillator circuit body 21 and a protective layer 22 disposed outside the LC oscillator circuit body 21. The LC oscillator circuit body 21 includes a conductor 211, and the protective layer 22 includes an opening exposing the conductor 211. A thermally conductive material layer contacts the conductor 211 through the opening. By directly contacting the conductor 211 with the thermally conductive material layer 200, the heat generated by the conductor 211 can be directly conducted to the thermally conductive material layer 200, improving heat dissipation efficiency. The conductor can constitute the inductor portion of the LC oscillator circuit body.
[0046] In some embodiments, the capacitor 212 of the LC oscillation circuit body 21 is disposed at one end of the notch filter 2, and the window is disposed adjacent to the capacitor 212. The capacitor 212 is the component in the notch filter 2 that generates the most heat. The placement of the window adjacent to the capacitor 212 allows the capacitor 212 to be in direct contact with the thermally conductive material layer 200, and the heat generated by the capacitor 212 can be directly conducted to the thermally conductive material layer 200, which significantly improves the heat dissipation efficiency.
[0047] In some embodiments, the notch filter 2 includes an LC oscillator circuit body 21, which includes a conductor 211 and a capacitor 212. The conductor can constitute the inductor portion of the LC oscillator circuit body. A thermally conductive material layer is in contact with the capacitor 212. In the LC oscillator circuit, the capacitor is the main heat source. Since part of the capacitor in the notch filter is exposed, the direct contact between the thermally conductive material layer and the capacitor 212 facilitates the direct conduction of the heat generated by the capacitor into the surrounding environment.
[0048] In some embodiments, combined with Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the radio frequency receiving device also includes a cable outlet 400, to which a cable 3 located outside the thermally conductive material layer 200 is connected. In other words, the signal processing unit 1 is connected to the cable outlet 400 via the cable 3. Here, the cable outlet 400 can be connected to other devices.
[0049] In some embodiments, the radio frequency receiving device is a flexible receiving device.
[0050] In some embodiments, the thermally conductive material layer 200 is a flexible thermally conductive material layer. Specifically, the thermally conductive material layer 200 is made of a flexible material, for example, it is made of glass fiber reinforced ceramic-filled silicone rubber material, which helps to increase the overall flexibility of the radio frequency receiving device.
[0051] In some embodiments, the protective outer cover 300 is made of multi-layer flame-retardant sponge, silk floss, or leather, etc. A cable outlet 400 is located outside the protective outer cover 300 so that it can be connected to other devices.
[0052] In some embodiments, the thickness of the radio frequency receiving device is between 10 mm and 30 mm.
