Fig. 1 shows a schematic structural view of an apparatus 100 for cleaning a lumen hole according to an embodiment of the present invention, and fig. 2 shows a schematic structural view of an embodiment of a bracket 110 of fig. 1. Referring to fig. 1 and 2, the apparatus 100 includes a support 110 and a moving member 130. The bracket 110 is formed with an arc-shaped bearing end 111 for attaching the cleaning member 112 in conformity with a portion to be cleaned of the cavity hole 200. The bracket 110 is mounted on the moving part 130, and the moving part 130 is used for driving the bracket 110 to move in the cavity 200, so that the cleaning part 112 on the bracket 110 cleans the part to be cleaned of the cavity 200 in the process of moving.

The portion of the bore 200 to be cleaned may include an inner wall of the bore.

Optionally, the moving member 130 is used to move the support 110 along the axial direction of the bore 200 so as to move the support 110 into and out of the bore 200 in a reciprocating manner. When the bracket 110 enters the cavity 200, the cleaning component 112 thereon performs cleaning, disinfection and other tasks, and when the bracket 110 exits the cavity 200, the cleaning component 112 can be replaced, supplied with cleaning agent and the like.

In one embodiment, when the bracket 110 is mounted on the moving member 130, the arc-shaped carrying end 111 thereof spans the moving member 130, so that a sufficiently wide cleaning range can be provided.

In one embodiment, the bore 200 may be a scanning chamber of a medical imaging apparatus, which is generally formed on a housing, and in which, for example, a scanning center and a region of interest disposed according to the scanning center are formed, and the moving member 130 may be a moving bed board of a bed of the medical imaging apparatus, which is generally used for carrying a patient and moving along an axial direction of the scanning chamber, wherein the scanning chamber is entered in a scanning preparation stage and a portion of the patient to be imaged is located in the region of interest, and the patient is carried out of the scanning chamber after the scanning is finished.

The bracket 110 may further include a support bracket 113 for supporting the arcuate bearing end 112. The support bracket 113 may be made of a resin material and the arcuate bearing end 112 may comprise, for example, a fiberglass material. The support bracket 113 may be hollow to reduce weight and facilitate handling. The arcuate bearing end 112 may be disposed on the support bracket 113 via an adhesive 114, which adhesive 114 may include a hook and loop fastener (or "velcro") and/or an adhesive.

The arc-shaped bearing end 111 is supported by the bearing bracket 113, so that the arc-shaped bearing end is not easy to damage and deform, and the stability of the bracket 110 during traveling is improved. In other embodiments, the arcuate bearing end 111 can be directly connected to the moving member 130 without being supported by optimized selection and design of materials, processes, structures, and the like.

The cleaning member 112 may be detachably disposed on the arc-shaped carrying end 111, for example, an adhesive member 115 is disposed on the arc-shaped carrying end 111 for adhering the cleaning member 112. The adhesive member 115 may include a hook and loop fastener capable of adhering the cleaning member 112 having a hair surface thereto, and the cleaning member 112 may be separated from the arc-shaped carrying end 111 when the cleaning member 112 is pulled or pulled by an external force. For another example, the cleaning member 112 may be formed into a loop portion that can be fitted over the arc-shaped carrying end 111 and that can be opened to be separated from the arc-shaped carrying end 111, for example, the loop portion may be formed by a strap with a buckle, and the cleaning member 112 may be detached from the arc-shaped carrying end by unbuckling the strap.

As shown in fig. 3, the cleaning member 112 itself may have elastic deformation capability to enable cleaning of the rugged portion. Taking the example of a scan chamber of a magnetic resonance imaging apparatus, the inner wall 210 may not be a flat surface, but may generate the protrusion 212 due to installing some working components such as an air outlet, when the cleaning component 112 passes the protrusion 212, the elastic deformation is generated so as to pass the protrusion 212 smoothly, and the protrusion and the surrounding corners or gaps can be cleaned.

As shown in fig. 4, in other embodiments, the cleaning member 112 can be connected to the arc-shaped bearing end 111 through the elastic connecting member (e.g. spring) 116, even if the cleaning member 112 itself has no or limited elastic deformation capability, and can smoothly pass through the protrusion 212 by virtue of the deformation of the elastic connecting member 116 when encountering the protrusion 212 during the traveling.

The cleaning member 112 may be provided as a single piece along the arc-shaped carrying end or may include a plurality of independently detachable portions.

Cleaning elements 112 may include a liquid absorbing material that may absorb, for example, water, alcohol, or other cleaning or sanitizing liquids/sprays. For example, the cleaning member 112 may include a sponge, a textile, or the like.

When the embodiment of the present invention is applied to a place where the requirement for hygiene is high, such as a medical imaging apparatus, it may further include a medical sterile cover (not shown) disposed outside the cleaning member 112.

The bracket 110 may further include a gimbal 119, which may be disposed on the support bracket 113, and in other embodiments, the gimbal 119 may be disposed directly on the arcuate bearing end 111. The gimbal includes a gimbal bar 117 extending along a direction in which the support 110 travels along the moving member 130, and the gimbal bar 117 is configured to be attached to a surface of the moving member 130 to enhance stability of the support 110 and prevent the support 110 from being tilted due to inertia or external force.

Further, the balance 119 may be a foldable tripod to save the space occupied by the stand 110 and to facilitate storage and carrying.

For example, the balance bar 119 may further include a fixed bar fixed to the support bracket, and a sliding bar (not shown) having one end hinged to one end of the fixed bar and the other end hinged to one end of the sliding bar, the other end being slidably connected to the fixed bar. When the sliding bar slides to one end of its sliding travel, the gimbal 119 is in an open delta stable state, at which point the gimbal 117 can engage the surface of the moving member 130. When the slide bar slides to the other end of its sliding stroke, the gimbal 119 is in a folded state.

The support 110 may be removably arranged on the mobile element 130 so as to carry the support 110 in the cavity 200 and perform cleaning only when the mobile element 130 is idle. For example, when it is detected that there is no patient to be imaged on the moving bed plate of the bed (for example, the previous patient has been scanned and another patient has not yet started scanning), the support 110 may be mounted on the moving bed plate, and the moving bed plate is controlled to travel within the travel range thereof, so that the inner wall of the scanning chamber is cleaned when the support 110 thereon passes through the scanning chamber.

In one embodiment, the moving member 130 is provided with a groove 131 on each side, and the bracket 110 is provided with a catch 118 at each end for engaging with the groove 131, and the catch 118 may be disposed on the support bracket 113. The catch 118 engages the wall of the corresponding recess 131 when operated to the first position and the catch 118 is releasable from the corresponding recess when operated to the second position. The above-mentioned operation of the catch 118 may include: the end of the clip 118 connected to the body of the bracket 110 is pressed to rotate the end of the clip 118 engaged with the groove 131 by a small angle from the initial position (the first position, for example, the position close to the body of the bracket 110) to the second position (for example, the position slightly away from the body of the bracket 110). The above-described operations on the catch 118 may further include: releasing the pressure returns the end of the latch 118 engaging the recess 131 to the initial position (first position) to engage the wall of the recess 131.

When the moving member 130 is used as a moving bed plate of a medical imaging apparatus, the recess 131 provided thereon may be a mounting groove for mounting a local coil (e.g., a head coil) which is required in some examinations and is not required in other examinations, and thus can be detached from the detection bed. Accordingly, the mounting slot may be reused to mate with the catch 118 of the stationary bracket 110 when the local coil is not in use, to clean the scanning chamber via the cleaning member on the bracket 110 as the moving platen travels through the scanning chamber. By multiplexing the mounting grooves of the local coils, the mounting and dismounting of the bracket 110 can be realized without changing the structure of the detection bed.

The support 110 may also be driven in other ways to travel within the bore for cleaning, for example, the moving part may comprise a robotic arm or even a device that can be manually driven.

Based on the above description, another embodiment of the present invention further provides a cleaning support, which has similar structure and operation principle as the support 110, for example, the support includes a support bracket, an arc-shaped bearing end disposed on the support bracket, the arc-shaped bearing end is adapted to the hole wall of the cavity to be cleaned and is used for attaching a cleaning component, and a mounting member disposed on the support bracket, the mounting member is used for connecting a moving component, so that the moving component drives the cleaning component on the cleaning support to clean the hole wall of the cavity in the process of traveling when traveling in the cavity.

The above-mentioned "fitting to the portion to be cleaned of the cavity" includes matching of at least one of size, shape, and structure.

In the device for cleaning a cavity hole and the cleaning bracket of the above embodiment, the arc-shaped bearing end corresponding to the part to be cleaned of the cavity hole is provided, the cleaning member is attached to the arc-shaped bearing end, and the bracket with the arc-shaped bearing end is mounted on the moving member, so that the cavity hole is cleaned by the reciprocating motion of the moving member relative to the cavity hole, and the problem that the cavity hole is difficult to clean due to size limitation is solved. And when being applied to medical imaging equipment, can utilize in the current design of medical imaging equipment, the reciprocating motion of moving bed board relative to scanning chamber realizes the cleanness of scanning chamber for can clean in the scanning flow or the clearance time between the scanning flow end and the beginning, promote clean quality and efficiency, promote medical imaging equipment's utilization ratio, and can not sweep into the influence to scanning flow.

The medical imaging device described above may include a magnetic resonance imaging device, a computed tomography device, and the like.

In the embodiment of the present invention, a magnetic resonance imaging apparatus shown in fig. 5 is taken as an example for explanation. As shown in fig. 5, the magnetic resonance imaging apparatus includes a scanner 510. The scanner 510 is used to perform a magnetic resonance scan of the subject (e.g., human body) 56 to generate image data of a region of interest of the subject 56, which may be a predetermined imaging site or imaging tissue.

The magnetic resonance imaging system may comprise a controller 520 coupled to the scanner 510 for controlling the scanner 510 to perform the procedure of the magnetic resonance scan described above. Specifically, the controller 520 may send sequence control signals to relevant components of the scanner 510 (e.g., a radio frequency generator, a gradient coil driver, etc., which will be described below) through a sequence generator (not shown in the drawings) so that the scanner 510 performs a preset scan sequence.

The scanner 510 may include a main magnet assembly 511 and a bed. The main magnet assembly 511 generally comprises an annular superconducting magnet defined within an outer housing, which is mounted within an annular vacuum vessel. The annular superconducting magnet and its housing define a cylindrical space surrounding the object 56, which forms a scanning chamber 580 with the moving couch 513 for carrying the object 56, the scanning chamber 580 having an inner wall with a substantially circular arc shape in cross section. The main magnet assembly 511 generates a constant magnetic field, B0 field, in the Z-direction of the scan bore 580 (the axial direction of the scan bore). Typically, the more uniform portion of the B0 field is formed in the central region of the main magnet.

The bed may comprise a support table 512, the above-mentioned moving bed plate 513 for carrying the object 56, and a support bridge 514 provided at a first opening of the scanning chamber 580, the support table 512 being for supporting the moving bed plate 513. The moving couch 513 is configured to travel in the Z direction to access the scanning chamber 580 from a second opening of the scanning chamber 580 in response to control by the controller 520, e.g., in one embodiment, the imaging volume of the subject 56 may be positioned to a central region of relatively uniform magnetic field strength in the scanning chamber to facilitate scanning imaging of the imaging volume of the subject 56.

The Z direction is generally a direction extending from the head to the feet (or from the feet to the head) when the object 56 is positioned on the moving bed 513, and in the present embodiment, one end of the positioning head is referred to as a front end and one end of the positioning feet is referred to as a rear end.

The rear end of the moving platen 513 enters the scanning chamber 580 from the second opening, and gradually advances out of the first opening of the scanning chamber 580 to meet the support bridge 514. The support bridge 514 may be integral with the housing of the main magnet assembly and may be used to support the moving couch plate and also to position some working components therein.

The scanner 510 may also include a radio frequency generator 515, a radio frequency transmit coil 516, a gradient coil driver 517, a gradient coil assembly 518, and a data acquisition unit 519.

The magnetic resonance imaging apparatus transmits a static magnetic pulse signal with the formed B0 field to the subject 56 located in the scan bore so that the precession of the protons of the resonance volume within the subject 56 is ordered, producing a longitudinal magnetization vector.

A radio frequency generator 515 is operative to generate radio frequency pulses, e.g., radio frequency excitation pulses, responsive to control signals from the controller 520, the radio frequency excitation pulses being amplified, e.g., by a radio frequency power amplifier (not shown), and applied to the radio frequency transmit coil 516 such that the radio frequency transmit coil 516 transmits a radio frequency field B1 orthogonal to the B0 field toward the subject 56 to excite nuclei within the resonating volume to produce transverse magnetization vectors Mxy.

The radio frequency transmit coil 516 may include, for example, a body coil disposed along the inner periphery of the main magnet, and when only a portion of the subject 56 is scanned, the radio frequency transmit coil 516 may also be a local coil, such as a head coil dedicated to head imaging. The local coils are typically positioned on the moving bed 513, for example, the moving bed 513 is provided with mounting slots (not shown) for positioning the head coils.

After the radio frequency excitation pulse ends, the proton group loses phase, the macroscopic transverse magnetization vector in the tissue gradually attenuates, and a free induction attenuation signal, i.e., a magnetic resonance signal which can be acquired, is generated in the process that the transverse magnetization vector of the object 56 gradually returns to zero.

The gradient coil drivers 517 are operable to provide the appropriate currents/powers to the gradient coil assembly 518 in response to gradient pulse control signals or shim control signals issued by the controller 520.

The gradient coil assembly 518 forms a varying magnetic field in the imaging volume to provide three-dimensional positional information for the magnetic resonance signals described above, on the one hand, and a compensating magnetic field for generating the B0 field to shim the B0 field, on the other hand.

The gradient coil assembly 518 may include three gradient coils for generating magnetic field gradients that are tilted into three spatial axes (e.g., X, Y, and Z axes), respectively, that are perpendicular to each other.

The data acquisition unit 519 is operative to acquire the magnetic resonance signals described above (e.g., received by the body coil or the surface coil) responsive to data acquisition control signals from the controller 520. The data acquisition unit 519 is further operative to store control signals responsive to data from the controller 520 to store the digitized magnetic resonance signals (or echoes) in K-space. The K-space is the filling space of the raw data of the magnetic resonance signals with spatially localized encoded information. Specifically, the data acquisition unit 519 fills the digitized magnetic resonance signals into the K-space in a specific manner in response to data storage control signals of the controller 520.

The magnetic resonance imaging apparatus may comprise an image reconstruction unit 530 for reconstructing an image of an imaging volume of the subject 56 based on the data stored in K-space.

The magnetic resonance imaging apparatus may include a display unit 550, which may be used to display an operation interface and various data, images or parameters generated during data acquisition and processing.

The magnetic resonance imaging device includes a console 560, which may include user input devices such as a keyboard and mouse, and the controller 520 may communicate with the scanner 510, the image reconstruction unit 530, the display unit 550, and the like in response to control commands generated by a user based on the console 560 or operation panels/buttons provided on the main magnet housing, and the like.

The apparatus for cleaning a bore according to the above-mentioned embodiment of the present invention may be used for the above-mentioned magnetic resonance imaging device, for example, the moving part 130 of the apparatus for cleaning a bore may include the moving bed 513 of the magnetic resonance imaging device, and the bracket 110 is mounted on the moving bed 513 through a mounting groove for mounting a head coil, so that the cleaning part 112 on the bracket 110 passes through the scanning chamber 580 to clean the inner wall of the scanning chamber 580 when the controller 520 controls the moving bed to travel in the Z direction. Such a cleaning process may be performed after the end of the scanning process, or may be performed during the scanning process as long as the head coil is not used in the scanning process.

In other embodiments, mounting features dedicated to mounting the bracket 110, such as the aforementioned recesses 131, may be provided on the moving bed 513.

It is understood by those skilled in the art that the computed tomography apparatus has a scanning chamber and a moving bed plate with a similar structure as the magnetic resonance imaging apparatus, and a detailed description thereof is omitted.

As shown in fig. 6, in combination with the above-mentioned example of the magnetic resonance imaging apparatus, an embodiment of the present invention may also provide a medical imaging apparatus 600, which may include a scan chamber 630, a moving bed 620, and a support bridge 640 disposed at an opening of the scan chamber 630. The moving bed plate 620 is capable of traveling in the scanning chamber 630 and reciprocally entering and exiting the opening 50 of the scanning chamber

In particular, the scanning chamber comprises two opposite openings 631, 632. The moving bed plate 620 is, for example, disposed to enter and exit the scanning chamber 630 from an opening 631 of the scanning chamber 630. The movable stage 620 may be supported by a support table 650, and the support table 650 may be fixedly installed at one end of a housing forming the scanning chamber 630, or may be a movable stage that can be separated from the housing. The support bridge 640 and the support table 650 may form a receiving space therein to receive some working components of the medical imaging apparatus 600, which may include, for example, a driving device for driving the movement of the moving bed 620.

In some examples, the support bridge 640, which may also be referred to as a rear bridge, is disposed at an opening at the rear side of the scan volume, while the support stage is disposed near an opening at the front side of the scan volume. Depending on the type and model of the medical imaging device, at least a portion of the support bridge 640 may be disposed outside the opening of the scanning chamber 630 or may be entirely within the scanning chamber 630. A support bridge 640 may be provided at another opening 632 of the scanning chamber 630 to support the moving bed plate 620 as it travels adjacent the opening 632 or as it extends out of the scanning chamber from the opening 632.

The medical imaging device may further include a bracket 610 having a similar structure to the bracket 110, for example, the bracket 610 is formed with an arc-shaped bearing end adapted to a portion to be cleaned (e.g., an inner wall) of the scanning chamber 630, the arc-shaped bearing end being used for attaching a cleaning member. The difference is that the bracket 610 is used to releasably connect the moving bed 620 or to releasably connect the support bridge 640. The support 610 may be disposed on the support bridge 640 when the medical imaging device is not in operation, and after the medical imaging device begins operation, the moving bed 620 triggers the support bridge to cyclically release and reconnect the support 610 after repeatedly traveling into contact with the support bridge 640, and after the support bridge 640 releases the support 610, the moving bed 620, through the connection with the support 610, carries the support 610 off the support bridge and into the scanning chamber 630 for cleaning operations.

For example, each time the moving bed 620 travels to a particular position (e.g., out of the opening 631) toward the support bridge 640, the support bridge 640 is triggered to release or reconnect the bracket 610. When the support bridge 640 releases the bracket 610, the movable bed plate 620 can move the bracket 610 in the scanning chamber 630 after leaving the specific position and clean the portion to be cleaned of the scanning chamber 630. The bracket 610 is reconnected to the support bridge 640 such that the moving bed 620 is separated from the bracket 610 when leaving the particular position.

The bracket 610 may be disposed at a fixed position on the support bridge 640, and the "specific position" may include: the position where the moving bed 620 contacts or connects with the bracket 610 on the support bridge 640.

Fig. 7 shows a schematic structural view when the bracket 610 is connected with the moving bed 620 and the support bridge 640, wherein, since the bracket 610 and the support bridge 640 are fixedly connected, when the moving bed 620 travels away from the support bridge 640, the bracket stays on the support bridge 640, resulting in the state shown in fig. 8. Fig. 8 illustrates a schematic structural view when the support is connected to the support bridge and separated from the movable bed board, fig. 10 illustrates a schematic structural view when the first connection member on the support is connected to the second connection member on the support bridge, wherein after the support 610 is connected to the support bridge 640 and separated from the movable bed board 620, the movable bed board 620 may carry a scanning object to perform imaging scanning, and during or after scanning, the movable bed board 620 returns and continues to move toward the support bridge 640, the support 610 is connected to the support 610 and drives the support bridge 640 to release the support 610, and after the support 610 is released from the support bridge 640, the support 610 is taken away by the movable bed board 620 to enter the scanning chamber for cleaning, so as to form a state illustrated in fig. 9, wherein fig. 9 illustrates a schematic structural view when the support is connected to the movable bed board and separated from the support bridge. During the process of moving the bed plate 620 again towards the support bridge 640, the support bridge 640 is driven to connect the bracket 610 again, thereby entering the state shown in fig. 7 again, and so on. Fig. 7-10 do not show the support bridge 640, however, show a second connector 670 disposed on the support bridge 640 that connects and releases with the stent 610 corresponding to the connection and release of the support bridge with the stent 610, respectively.

As shown in fig. 7-10, in one embodiment, the bracket 610 is provided with a first connector 660 and the support bridge 640 is provided with a second connector 670. The moving bed 620 includes a driving portion 635 formed to extend outward (e.g., in a traveling direction of the moving bed 620) from an end of the moving bed 620, the driving portion 635 being configured to drive the second connection member 670 such that the second connection member 670 is located at a connection position (e.g., in a state shown in fig. 7) connected to the first connection member 660 or a release position (e.g., in a state shown in fig. 9) for releasing the first connection member 660 when the moving bed 620 travels to the specific position.

Specifically, the first coupling member 660 includes a hook portion 662 (shown in fig. 9 and 10), which is formed, for example, in a hook shape. The second connector 670 includes a fixed portion (not shown) and a rotating portion 671. The fixing portion is provided on the support bridge 640, for example, at least one end of the fixing portion is fixed on the support bridge 640, and the other end is connected to a central axis passing through a rotation center of the rotation portion 671.

An outer end of the rotating portion 671 (e.g., an end closer to an outer side edge of the moving bed plate 620) is circumferentially provided with a plurality of elastically stretchable protrusions 672, and an inner end of the rotating portion 671 (e.g., an end farther from the outer side edge of the moving bed plate 620) is circumferentially provided with a plurality of stoppers 673. A relief gap 674 is formed between adjacent two of the blocking portions 673. The driving portion 635 on the movable plate 620 pushes one of the protrusions 672 to rotate the rotating portion 671 to the connection position or the release position in at least one stroke of the movable plate 620. Wherein, in the coupling position, one of the plurality of blocking portions 673 is caught with the hook portion 662 of the first coupling member 660 and, in the release position, the hook portion 662 is located in one of the release gaps 674 adjacent to the blocking portion 673.

In one embodiment, the drive 635 includes an end 681 and a wall 682. The end 681 can be a free end of the drive portion 635 opposite the support bridge 640, and the wall 682 can include at least a bottom surface and a side surface respectively connected to the end. During the at least one stroke of the movable plate 620, the end 681 of the driving portion 635 pushes one of the protrusions 672 (e.g., a first protrusion) of the rotating portion 671 to rotate the rotating portion 671 until the first protrusion is located above the driving portion 635 and abuts against a wall 682 of the driving portion, e.g., an upper bottom surface of the wall 682 as shown in fig. 7.

The wall 682 of the driver 635 further includes angled sides 683, which can oppose the rotator 671, and a groove 684 in communication with the angled sides 683. During the at least one stroke of moving the bed plate 620, another projection 672 (e.g., a second projection) adjacent to the first projection being pushed slides along the sloped side 683 into the groove 684 (as shown in fig. 7). On the way of the moving bed plate 620 back from the specific position (traveling away from the support bridge 640 in the opposite direction), the second protrusion located in the groove 584 leaves the driving portion 635 along the inclined side 683 (as shown in fig. 8). During at least one stroke of the moving bed plate 620 to travel to the specific position again (to travel toward the support bridge 640), the driving portion 635 pushes the projection 672 (second projection) away from the inclined side 683 to drive the rotating portion 671 to continue rotating.

In one embodiment, each adjacent two of the protrusions 672 has a fixed arc (or spacing) therebetween, such that the driving portion 635 drives the rotating portion 671 to rotate by a fixed arc by pushing one protrusion 672 (e.g., the first protrusion described above) at a time, at which the first protrusion is located above the driving portion 635, the second protrusion (the protrusion 672 adjacent to the first push start and to be pushed next) is located in the groove 684, and the hook portion 662 of the first connection member 660 is engaged with one of the plurality of blocking portions 673. Then, when the movable plate 620 moves away from the support bridge 640 in the opposite direction, the first protrusion and the second protrusion of the rotating portion 671 act on the driving portion 635 together to prevent the driving portion 635 from driving the rotating portion 671 to rotate in the opposite direction. When the moving plate 620 is moved away from the support bridge 640, since the end 681 of the driving part 635 is just opposite to the next projection 672 (second projection) so that the moving plate 620 is returned again, and then the second projection is pushed to drive the rotation part 671 to rotate by a fixed arc, the third projection just slides into the groove 684, and at this time, the blocking part 673 is separated from the hook part 662 of the first coupling 660 and the hook part 662 is just located in the release space 674 adjacent to the blocking part 673. When the moving bed 620 travels away from the support bridge 640 again in the reverse direction, the bracket 610 is released from the support bridge 640, and thus moves into the scanning chamber 630 again with the moving bed 620 for cleaning (as shown in fig. 9).

In one embodiment, the bracket 610 is releasably connected to the moving bed 620 by means of hook and loop fasteners, for example, velcro members that can be adhered to each other are provided at the end of the moving bed 620 near the end of the supporting bridge 640 and at the end of the bracket 610 near the moving bed 620, so that the bracket 610 can be releasably connected to the moving bed 620.

In other embodiments, the bracket 610 may also be releasably connected to the movable bed 620 by way of magnetic attraction.

In the medical imaging device of the embodiment, the bracket comprises the arc-shaped bearing end which is adaptive to the part to be cleaned of the cavity hole, the cleaning part is attached to the arc-shaped bearing end, and the bracket can clean the cavity hole along with the moving part in the scanning cavity, so that the problem that the cavity hole is difficult to clean due to size limitation is solved. And the support can both connect and remove the bed board and can connect the support bridge, utilizes the reciprocating motion of removing the bed board relative to the support bridge to trigger or unblock the relation of connection of support bridge and support circularly for can realize the cleanness to the scanning chamber at the scanning clearance, promote clean quality and efficiency, promote medical imaging equipment's utilization ratio, and can not sweep into the influence to scanning flow.
