The MRI system 100 includes a main magnet 110, the main magnet 110 having a scanning bore 112 for receiving a test object therein.

The main magnet 110 is provided with superconducting coils 114, gradient coils 116, and a Radio Frequency (RF) body coil 118. The superconducting coils 114 are used to apply a static magnetic field to produce longitudinal macroscopic magnetization vectors of the body part of the examination subject located in the scanning chamber 112. The radio frequency body coil is used for applying radio frequency pulses to excite longitudinal magnetization vectors of a body part of a detection object to turn over so as to generate transverse magnetization vectors, and after the radio frequency excitation pulses are finished, the transverse magnetization vectors are attenuated at a fixed angular frequency so as to generate free induction attenuation signals which can be collected as magnetic resonance signals. The gradient coils 116 are used to apply gradient pulses to superimpose linear magnetic field gradients on the static magnetic field B0 to achieve spatial localization of the magnetic resonance signals such that the acquired magnetic resonance signals of the tracks have spatial location information.

The MRI system 100 further includes a receiving coil 130 for receiving the magnetic resonance signal generated by the body part of the subject, and the receiving coil 130 may be disposed on the examination couch 120 and as close as possible to the part of the subject to be imaged. In other embodiments, the radio frequency body coil may be configured to receive the magnetic resonance signal when switched from a transmit mode to a receive mode.

The MRI system 100 of the present embodiment further includes a control device 140, a pulse generator 150, a transmitter 160, a gradient power supply 170, a receiver 180, and an image reconstructor 190.

The control device 140 receives data from the pulse sequencer 150, the data including information such as waveforms and timings of the RF pulses and gradient pulses used in the sequence. The control means 140 controls the transmitter 160 based on data of the RF pulses in the sequence to control the gradient power supply 170 based on data of the gradient pulses.

The transmitter 160 provides current to the RF body coil 118 based on data received from the control device 140. The gradient power supply 170 provides current to the gradient coils 116 based on data received from the control device 140.

The receiver 180 applies processing (such as demodulation/detection) to the magnetic resonance signals received by the receive coil 130 and outputs the resulting signals to an image reconstructor 190 for image reconstruction to acquire a magnetic resonance image of any slice or volume of the subject.

Although not shown in the figures, it will be understood by those skilled in the art that the above-described MRI system 100 may also include a storage device for storing control instructions and image signals/data, a display for displaying images, an input device for inputting control instructions/parameters, and other devices for facilitating magnetic resonance imaging. As shown in fig. 1, the MRI system of the present invention further includes a test bed 120, which is generally disposed at an end of the scanning chamber 112 and is configured to carry the test object for movement so that the test object can enter/exit the scanning chamber 112. The control device 140 may also be used to control the lifting, translation, etc. of the detection bed 120 to position the detection object.

Fig. 2 shows a schematic structural diagram of a detection bed according to an embodiment of the present invention, wherein the detection bed can be applied to the magnetic resonance imaging system shown in fig. 1 as an example of the detection bed 120 in fig. 1. Fig. 3 shows an exploded view of the mobile carriage of fig. 2. FIG. 4 is a schematic diagram of the detection bed of FIG. 2 in an extended state; fig. 5 shows a schematic structural view of the moving carriage in fig. 4. As shown in fig. 2 to 5, the examination bed of the present embodiment includes a movable carriage 200 and a base 300 for supporting the movable carriage 200. Wherein the mobile carrier 200 can move relatively to the base 300, for example, the mobile carrier 200 can move toward the main magnet or away from the main magnet along the Z-axis direction of the magnetic resonance imaging system (central axis direction of the main magnet) to position the test object to a position required for imaging.

The movable bracket 200 includes a base 210 and an extension portion 230, wherein an accommodating space is provided along one end of the base 210, and one end of the extension portion 210 extends into the accommodating space and can move toward the base 210 or move away from the base 210 to adjust the length of the movable bracket 200. In one embodiment, the other end of the base 210 may be used to mount, for example, a driving device (not shown) for driving, for example, the translational movement of the mobile carriage 200.

Figures 6 and 8 show the base 210 and the extension 230 of figure 2 in enlarged form, respectively; fig. 7 shows the slide guide device on the base in fig. 6 in an enlarged manner; figure 9 shows the speed-limiting catch and the protruding member on the extension of figure 8 in an enlarged view. As shown in fig. 2 to 7, the base 210 includes a top plate 211 and a bottom plate 213 connected to the top plate, and a receiving space 215 is formed between the top plates 211 and 213. The receiving space 215 is used to receive one end of the extension part 230 so that the extension part 230 can be further pushed toward the base part 210 or the extension part 230 can be pulled outward in the opposite direction by operating the other end of the extension part 210. Fig. 9 shows a state in which the extension part 230 is coupled to the body part 210, and as shown in fig. 10, the body part 210 and the extension part 230 form a structure similar to a drawer.

Referring to figures 6 and 7, the base plate 213 of the base 210 is provided with slide guides 214 for engaging the extension 230. for example, slide guides 214 may be provided on opposite sides of the base plate 213 to limit/guide movement of the extension 230 in a particular direction. Accordingly, the extension 230 may also be provided with a sliding device to fit the sliding guide 214, which includes but is not limited to a sliding rail, a sliding groove, a sliding block, etc.

Referring to FIG. 9, the back of the extension 230 is shown facing the ground when the test bed 200 is in use. As shown in fig. 9, the extension portion 230 is provided with a plurality of speed-limiting slots 231, and the base portion 210 is provided with a protruding member 217 capable of protruding into any one of the speed-limiting slots 231. In this way, the speed of the extension 230 moving relative to the base 210 can be appropriately limited, and potential safety hazards due to excessive pushing and pulling can be prevented. Further, the plurality of speed-limiting catching grooves 231 have concave arc-shaped surfaces, respectively, and are sequentially spaced apart to form a wave shape, so that the protruding pieces 217 may be sequentially engaged with the speed-limiting catching grooves 231 during the movement of the extension part 230, so that the extension part 230 moves smoothly. In other embodiments, the speed-limiting slot may be disposed on the base 210 and the protrusion may be disposed on the extension 230, as long as the engagement between the two is achieved.

Referring to fig. 2 to 9, an operating unit 240 for operating the extending portion 230 to move toward or away from the base portion 210 is connected to the other end (i.e., the end away from the base portion 210) of the extending portion 230, and a handle 241 is disposed on the operating unit 240, so that the extending portion 230 can be driven to move relative to the base portion 210 by the operating handle 241.

The upper surface of the operating component 240 is substantially coplanar with the upper surface of the base 210, so that when the extension 230 is fully extended into the receiving space 215, the operating component 240 and the base 210 can be substantially seamlessly interfaced to facilitate maintenance and a more comfortable experience for the test subject.

With continued reference to fig. 3, 5 and 6, the operating assembly 240 may be provided with an electrical connector 250, the electrical connector 250 is connected with a cable, and the cable extends from the electrical connector 250 to the base 210, passes through the base 210, and is guided to the base 300 by a first cable guide 500 disposed below the base 210.

In this embodiment, the first cable guiding device 500 may be a tank chain, wherein the cable may provide signal transmission between the detection bed and the control device of the MRI system, for example, when the detection bed is applied to the MRI system shown in fig. 1, the control device 140 sends a control signal to the detection bed through the cable in the first cable guiding device 500 to control the lifting and lowering of the detection bed, the translation of the moving bracket on the detection bed, and the like.

The electrical connector 250 may be used for connecting a surface coil, which may be used for receiving magnetic resonance signals generated by the examination object, as previously described, and the electrical connector 250 and the cable connecting thereto may be used for providing signal transmission between the surface coil and the control device and/or the image reconstructor of the MRI system.

Referring to fig. 8-10, as an example, a wire hole 219 is provided in the base 210, through which wire may be passed such that a first portion of the wire may be positioned below the base 210 (e.g., between the base 300 and the base 210), which may be disposed in the first wire guide 500 along with some other wire of the test bed.

In order to avoid the second part of the cable, i.e. the part between the electrical connector 250 and the base 210, from being twisted, crossed, etc. during the movement of the extension 230, a second cable guiding means 600 may be provided between the electrical connector 250 and the base for guiding this second part of the cable. Here, the second portion of the cable is the portion above the upper surface of the bottom plate 213 of the base 210 in fig. 8, and is also located in the accommodating space 215 of the base 210 when the extension part 230 is fully extended into the accommodating space 215.

Specifically, one end of the second wire guide 600 is disposed near the corresponding electrical connector 250, and the other end may be fixed to the base 210, for example, as shown in fig. 8, the base 210 is provided with a fixing block 212 for fixing the other end of the second wire guide 600, and the fixing block 212 may be disposed near the wire hole 219, for example, in order to optimize the space. The second cable guide 600 may be configured, for example, as a U-shaped structure, to guide the second portion of the cable in a manner that complements the lengths of the opposite ends of the U-shaped structure during movement of the extension 230 (e.g., one end of the U-shaped structure becomes longer and the other end becomes shorter). In other embodiments, the second cable guide 600 may be provided in other shapes as desired.

While the above describes a cable guide solution by passing the cable through the cable hole 219, in some applications, other types of cables/wires on the mobile carrier 200 may also be passed through the cable hole 219 so as to be able to be connected to other devices outside the examination bed, such as a control device, via the first cable guide 500. For example, in figure 10, a balun assembly 700 is shown, the wires at one end of the balun assembly 700 extending and being connected to the end of the mobile carrier 200 remote from the extension 300, the wires at the other end of the balun assembly 700 being arranged in the first cable guide 500 after passing through the wire holes 219.

The number of the electrical connectors 250 may be two or more, and the number of the corresponding cables may also be two or more.

In other embodiments, the receiving coil and corresponding electrical connector 250 may not be provided on the extension 300, and accordingly, the second cable guide 500 need not be used, depending on the design requirements of the MRI system.

Referring to fig. 11, which shows a schematic structural view of an examination bed according to another embodiment of the present invention, the movable bracket 200 includes a housing 800 disposed outside the base 210, and dust-proof devices 900 for shielding a gap between the extension 230 and the housing 800 are disposed on both sides of the extension 230, and the dust-proof devices 900 may include, for example, brushes. As shown in fig. 11, the length of the housing 800 is slightly longer than that of the base 210, and the length of the housing 800 may be, for example, the end of the housing 800 is substantially in the same plane as the end of the operating assembly 240 when the extension 230 is in the initial installation position, i.e. the extension 230 is substantially accommodated in the accommodating space 215 of the base 210, so as to ensure the integrity of the appearance of the examining bed, and the dust-proof device 900 may be used for: when the extension part 230 is pulled out for increasing the length of the moving bracket 200, a gap with the housing 800 due to its smaller width than the base part 210 is shielded.

Although the above describes the case of applying the detection couch to the MRI system, it should be understood by those skilled in the art that the detection couch of the present embodiment may also be applied to other medical detection systems, such as a Computed Tomography (CT) imaging system. Similarly, when applied to a CT system, the examination bed may comprise a base and a movable support, wherein the movable support comprises a base and an extension, an accommodation space is provided along one end of the base, and one end of the extension extends into the accommodation space and can move towards or away from the base to adjust the length of the movable support.

In addition, the standardized detection bed can be designed to be suitable for the requirements of different series/models of medical detection systems on the length of the detection bed. Moreover, the detection bed of the embodiment of the invention does not bring extra complicated operations, for example, when the extension part is in any state, the movable bracket 200 can be lifted without resetting or other preparation work in advance,

some exemplary embodiments have been described above, however, it should be understood that various modifications may be made. For example, suitable results may be achieved if the described techniques are performed in a different order and/or if components in the described systems, architectures, devices, or circuits are combined in a different manner and/or replaced or supplemented by additional components or their equivalents.
