Description

Technical Field

[0001] The technology of the present invention relates to a bed for a medical image photographing apparatus. Background Art

[0002] In medical facilities, medical image photographing apparatuses such as MRI (Magnetic Resonance Imaging) apparatuses and CT (Computed Tomography) apparatuses are used. Such a medical image photographing apparatus includes a bed. The bed includes: a top plate on which a subject (patient) lies; a base portion provided on the ground side; a lifting mechanism provided between the top plate and the base portion and configured to adjust the height of the top plate; and a cylindrical cover that covers the periphery of the lifting mechanism.

[0003] The cover has a structure that can be telescopically expanded and contracted up and down according to the driving of the lifting mechanism. A bed for a medical image photographing apparatus having a bellows structure cover as a structure that can be telescopically expanded and contracted up and down is disclosed in Patent Document 1, Patent Document 2, and Patent Document 3.

[0006] Patent Document 3: Japanese Unexamined Patent Application Publication No. 2017-018599

[0007] When the cover is soiled and / or damaged, it can be removed and replaced. Conventionally, when removing the cover from the bed to replace the cover, since the cover is cylindrical, a method of folding the cover like taking off a skirt and passing it under the base portion to remove it has been adopted. However, if this method is used, many complicated operations are required, such as jacking up the base portion and inserting a block under the base portion to ensure a space for the cover to pass under the base portion. The same many complicated operations are also required when installing the cover on the bed.

[0008] The bed of the medical image photographing apparatus has equipment such as the aforementioned lifting mechanism, or a sliding mechanism of the top plate, or a belt for fixing the position of the subject on the top plate, and thus is relatively heavy. Therefore, in the above conventional method, the burden on the staff is very large. Therefore, in the bed of the medical image photographing apparatus, a countermeasure for facilitating the attachment and detachment of the cover is required. Summary of the Invention

Detailed Embodiment

[0045] As an example, as Figure 1 and Figure 2 shown, the MRI apparatus 10 is composed of a gantry 11 and a bed 12. The gantry 11 is in a cylindrical shape with an imaging space in the center, and the imaging space is a cavity with a circular cross - section. Inside the gantry 11, there are a magnet and coils for generating a magnetic field in the imaging space, a detector for detecting the nuclear magnetic resonance signals emitted by the subject passing through the imaging space, etc. The MRI apparatus 10 is an example of the "medical imaging apparatus" related to the technology of the present invention. Also, the bed 12 is an example of the "bed of the medical imaging apparatus" related to the technology of the present invention.

[0046] The bed 12 includes a top plate 15, a caster unit 16, a lifting mechanism 17 (refer to Figure 2 ), and a cover sleeve 18, etc. The top plate 15 is for the subject to lie on. The caster unit 16 is provided on the ground side opposite to the top plate 15. A plurality of casters 19 are installed on the caster unit 16. Through the caster unit 16, the bed 12 can move within the medical facility. A foot cover is installed on the caster unit 16 to prevent the casters 19 from touching the feet. The caster unit 16 is an example of the "base part" related to the technology of the present invention.

[0047] The lifting mechanism 17 is disposed between the top plate 15 and the caster unit 16. The lifting mechanism 17 is a so-called scissor lift, which has an X-shaped telescopic arm connected to the top plate 15 and the caster unit 16 and a cylinder that applies a driving force to the telescopic arm. The lifting mechanism 17 adjusts the height of the top plate 15 by lifting or lowering the top plate 15 relative to the caster unit 16. The shroud 18 is in a substantially square tube shape that surrounds the periphery of the lifting mechanism 17 and can be telescopically extended or retracted up and down according to the drive of the lifting mechanism 17. In addition, in addition to these top plate 15, caster unit 16, lifting mechanism 17, and shroud 18, the bed 12 also includes a sliding mechanism for sliding the top plate 15 into the imaging space of the frame 11, a lacing for fixing the position of the subject on the top plate 15, and other equipment.

[0048] On one side of the bed 12 facing the frame 11, a connector (not shown) is provided. This connector is mechanically and electrically connected to the connector (not shown) of the frame 11. And, a docking pedal 20 is provided at the end of the caster unit 16 on the side opposite to the frame 11. By pressing the connector of the bed 12 into the connector of the frame 11 while stepping on this docking pedal 20, the bed 12 can be mechanically and electrically connected to the frame 11. And, by stepping on the docking pedal 20 again and pulling out the connector of the bed 12 from the connector of the frame 11, the bed 12 can be detached from the frame 11. That is, the bed 12 is a so-called dockable bed that can be attached and detached to and from the frame 11 without performing any operations such as loading and unloading of cables.

[0049] As an example, as Figure 3 and Figure 4 shown, the shroud 18 is a bellows structure composed of a sheet 25 and a frame member 26. The sheet 25 constitutes the entire shroud 18 and is made of a flexible material, such as cloth, resin, leather, carbon fiber, etc. The frame members 26 are arranged at equal intervals between the upper end 27 on the top plate 15 side and the lower end 28 on the caster unit 16 side. Contrary to the sheet 25, the frame members 26 are made of a rigid raw material, such as a metal slender tube (refer to Figure 7 ), etc. The frame members 26 extend in the horizontal direction and are bent at several places, and surround the periphery of the lifting mechanism 17 and are rectangular, and they function as a skeleton for maintaining the shape of the sheet 25 in a substantially square tube shape. And, when the sheet 25 is telescopically extended or retracted up and down according to the drive of the lifting mechanism 17, the frame members 26 also function as the protruding portions of the bellows structure. In addition, the top plate 15 and the upper end 27, and the caster unit 16 and the lower end 28 are detachably connected at multiple parts by screws (not shown).

[0050] When viewed from above, the cover 18 is formed into a rectangle with two short sides 29 and 30 and two long sides 31 and 32 by the frame member 26. The short side 29 of the two short sides 29 and 30 is the short side on the side of the frame 11, and is in a straight line shape intersecting the two straight long sides 31 and 32 at a right angle. On the other hand, the short side 30 on the side opposite to the short side 29 is in a curved shape and has no corners with the two long sides 31 and 32. Thus, the "rectangle" related to the technology of the present invention also includes a substantially rectangular shape (semi-elliptical shape or elliptical shape) in which the long side and the short side are connected in a curved shape and the boundary between the long side and the short side is not clear. In addition, terms such as "right angle" and "straight line" refer not only to a complete right angle and a straight line, but also to a right angle and a straight line including an error within the range generally allowed in the technical field to which the technology of the present invention belongs and not violating the gist of the technology of the present invention.

[0051] An opening / closing portion 35 is provided at the center of the short side 29 on the side of the frame 11. The opening / closing portion 35 is constituted by a cut 36 that vertically cuts the cover sheet 25 and the frame member 26 in a vertical line shape from the upper end 27 to the lower end 28. Therefore, the opening / closing portion 35 can be opened and closed. And a bending portion 37 is provided at the center of the short side 30 opposed to the opening / closing portion 35. As Figure 4 shown, the bending portion 37 bends when the opening / closing portion 35 is opened. Through these opening / closing portion 35 and bending portion 37, the cover 18 has a structure like the blade portion of a nail clipper.

[0052] As described above, the frame member 26 extends in the horizontal direction. And the cut 36 constituting the opening / closing portion 35 vertically cuts in a straight line shape from the upper end 27 to the lower end 28. Therefore, it can be said that the frame member 26 extends in a direction crossing the opening / closing portion 35, more specifically, in a direction orthogonal to the opening / closing portion 35. The horizontal direction is an example of the "direction crossing the opening / closing portion" related to the technology of the present invention.

[0053] The plurality of frame members 26 are in similar shapes that become smaller in size as they go from the upper end 27 toward the lower end 28. And the plurality of frame members 26 are arranged in such a manner that the centers of the short sides 29 are vertically aligned in the vertical direction. Therefore, when the cover 18 is viewed from the left-right direction, the surface on the short side 30 side is inclined inward from the upper end 27 toward the lower end 28 (refer to Figure 2 ). And when the cover 18 is viewed from the front-back direction, the surfaces on the long side 31 and 32 sides are inclined inward from the upper end 27 toward the lower end 28 (refer to Figure 5 etc.).

[0054] As an example, as Figure 5 and Figure 6As shown, in the cover sheet 25, one end 40 and the other end 41 facing each other at the opening / closing part 35 are detachably connected by a hook-and-loop fastener 42. The hook-and-loop fastener 42 is installed between a plurality of frame members 26. The hook-and-loop fastener 42 is composed of a set of hooks 43 installed at one end 40 and loops 44 installed at the other end 41 at positions corresponding to the hooks 43 (refer to Figure 6 ). The hook-and-loop fastener 42 is an example of the "detachable component" related to the technology of the present invention.

[0055] In the cover sheet 25, at the opening / closing part 35, one end 40 is arranged on the outside and the other end 41 is arranged on the inside, and one end 40 and the other end 41 overlap. Thus, one end 40 covers the other end 41 and further the hook-and-loop fastener 42 in a manner that is not visible from the outside.

[0056] As an example, as Figure 7 shown, in one end 50 and the other end 51 of the frame members 26 facing each other at the opening / closing part 35, the outer diameter φA of one end 50 is slightly thinner than the inner diameter φB of the other end 51. Therefore, as shown on the lower side of the arrow, one end 50 can be inserted into the other end 51. That is, the frame members 26 are detachably connected by fitting one end 50 and the other end 51 facing each other at the opening / closing part 35.

[0057] Alternatively, the following structure can be adopted. That is, the inner diameters of one end 50 and the other end 51 are made the same. And a cylindrical metal piece having an outer diameter slightly thinner than the inner diameter of one end 50 or the other end 51 is inserted into one of one end 50 and the other end 51 and riveted and fixed. Then, the metal piece is inserted into the inside of the other of one end 50 and the other end 51, thereby fitting one end 50 and the other end 51. Or, the outer diameters of one end 50 and the other end 51 are made the same. And a cylindrical metal piece having an inner diameter slightly thicker than the outer diameter of one end 50 or the other end 51 is inserted into one of one end 50 and the other end 51 and riveted and fixed. Then, the other of one end 50 and the other end 51 is inserted into the inside of the metal piece, thereby fitting one end 50 and the other end 51.

[0058] As an example, as Figure 8 shown, at the bending part 37, the frame members 26 are cut off and only connected by the cover sheet 25. Thus, when the opening / closing part 35 is opened, the bending part 37 bends.

[0059] Next, the operation of the above structure will be described. First, when installing the cover 18 on the bed 12, the hooks 43 of the hook-and-loop fastener 42 at one end 40 are detached from the loops 44 of the hook-and-loop fastener 42 at the other end 41 of the cover sheet 25 to release the connection between one end 40 and the other end 41. And one end 50 is pulled out from the other end 51 of the frame members 26 to release the fitting between one end 50 and the other end 51. Thus, the opening / closing part 35 can be opened.

[0060] Next, as Figure 4 shown, the opening / closing part 35 is opened with the bending part 37 as a fulcrum. Then, the cover 18 is inserted between the top plate 15 and the caster part 16 from the side opposite to the frame 11, and the cover 18 is moved horizontally in the direction of the frame 11, so that the cover 18 covers the lifting mechanism 17.

[0061] After that, one end 50 of the frame member 26 is inserted into the other end 51 so that the one end 50 is fitted and connected to the other end 51. Also, the bristles 43 of the hook-and-loop fastener 42 at one end 40 of the cover 25 are attached to the loops 44 of the hook-and-loop fastener 42 at the other end 41 to connect the one end 40 and the other end 41. Further, a plurality of parts of the top plate 15 and the upper end 27 and a plurality of parts of the caster part 16 and the lower end 28 are connected by screwing and fastening.

[0062] When the cover 18 is detached from the bed 12, the steps are substantially the same. That is, the bristles 43 of the hook-and-loop fastener 42 at one end 40 are detached from the loops 44 of the hook-and-loop fastener 42 at the other end 41 of the cover 25 to release the connection between the one end 40 and the other end 41. Also, the one end 50 is pulled out from the other end 51 of the frame member 26 to release the fitting between the one end 50 and the other end 51. Next, the opening / closing part 35 is opened with the bending part 37 as a fulcrum. Then, the cover 18 is moved horizontally in the direction opposite to the frame 11, so that the cover 18 is withdrawn from between the top plate 15 and the caster part 16.

[0063] As described above, the bed 12 includes: a top plate 15 on which the subject lies; a caster part 16 provided on the ground side; a lifting mechanism 17 provided between the top plate 15 and the caster part 16 and used to adjust the height of the top plate 15; and a cover 18 that covers the periphery of the lifting mechanism 17 and is cylindrical, and can be telescopically extended and retracted according to the drive of the lifting mechanism 17. As Figure 3 and Figure 4 shown, the cover 18 has an opening / closing part 35 that can be opened and closed and is formed by a cut 36 longitudinally cut from the upper end 27 on the top plate 15 side to the lower end 28 on the caster part 16 side.

[0064] Conventionally, when detaching the cover 18 from the bed 12, in order to fold the cover 18 and pass it under the caster portion 16 to remove it, it was necessary to perform a number of complicated operations such as detaching the bed 12 from the frame 11, then lifting the caster portion 16 and inserting a block under the caster portion 16 to ensure a space for the cover 18 to pass through under the caster portion 16. In contrast, according to the technology of the present invention, it is only necessary to open the opening / closing portion 35 and move the cover 18 horizontally to remove it. The same applies when installing the cover 18 on the bed 12. Therefore, the cover 18 can be easily attached and detached. This effect is particularly valuable for the bed 12 of the MRI apparatus 10 which is relatively heavy and for which operations such as lifting impose a large burden on the staff.

[0065] Moreover, in the conventional method, during factory assembly, after installing the cover 18, the top plate 15 etc. are installed. Therefore, the assembly staff must be careful not to stain and / or damage the cover 18 during the operations after installing the cover 18. In contrast, according to the technology of the present invention, it is only necessary to install the cover 18 after all other operations are completed, so the assembly staff can perform the operations without any concerns.

[0066] Furthermore, in the conventional method, there are various design restrictions in order to facilitate the attachment and detachment of the cover 18. For example, the cover 18 is made into a cylindrical tube shape, or components such as the docking pedal 20 that protrude outward are not provided on the caster portion 16 as much as possible. In contrast, according to the technology of the present invention, such restrictions can be avoided, and the cover 18 etc. can be freely designed. That is, it can be configured such that, when viewed from the left - right direction, the surface on the short - side 30 side inclines inward from the upper end 27 toward the lower end 28, or when viewed from the front - rear direction, the surfaces on the long - side 31 and 32 sides incline inward from the upper end 27 toward the lower end 28. Thus, by applying a gradient to the cover 18, the cover 18 and thus the bed 12 can have a neat appearance, and the sense of oppression on the patient as the subject can also be reduced. And the docking pedal 20 etc. can be provided on the caster portion 16 without hesitation.

[0067] As Figure 3 and Figure 4 shown, the cover 18 has a bellows structure composed of a flexible cover sheet 25 and a plurality of frame members 26 extending in a direction intersecting the cut 36. As a structure that can be telescopically expanded and contracted up and down according to the drive of the lifting mechanism 17, in addition to the bellows structure, a telescopic structure can also be cited, but compared with the telescopic structure, the bellows structure is simple and inexpensive. Therefore, according to the bellows structure, a simple and inexpensive bed 12 can be provided.

[0068] As Figure 5 and Figure 6As shown, in the cover 25, one end 40 and the other end 41 that face each other at the opening / closing part 35 are detachably connected by a hook-and-loop fastener 42. Therefore, at the opening / closing part 35, the cover 25 does not sag loosely, thus being able to beautify the appearance. Moreover, the hook-and-loop fastener 42 is easy to attach and detach. Also, the hook-and-loop fastener 42 is as thin as the cover 25, so it does not interfere with the folding of the cover 25.

[0069] As Figure 5 and Figure 6 shown, in the cover 25, one end 40 that faces the other at the opening / closing part 35 is arranged on the outside and the other end 41 is arranged on the inside. One end 40 overlaps the other end 41 and covers the other end 41. Therefore, the appearance can be beautified and the user will not be aware of the opening / closing part 35.

[0070] As Figure 7 shown, the frame member 26 is detachably connected by fitting one end 50 and the other end 51 that face each other at the opening / closing part 35. Therefore, the frame member 26 can be easily attached and detached.

[0071] As Figure 3 and Figure 4 shown, the cover 18 has a bent part 37 that bends when the opening / closing part 35 is opened. Therefore, the opening / closing part 35 can be easily opened.

[0072] As Figure 8 shown, at the bent part 37, the frame member 26 is cut off and only connected by the cover 25. Therefore, the bent part 37 can be made simply and inexpensively.

[0073] As Figure 3 and Figure 4 shown, the cover 18 is rectangular with short sides 29 and 30 and long sides 31 and 32 when viewed from above, and the opening / closing part 35 is provided on the short side 29. Therefore, the opening width of the opening / closing part 35 can be made larger, so that the cover 18 can be more easily attached and detached. Also, the way of providing the opening / closing part 35 on the short side 29 is suitable for the case where there is space on the left and right of the bed 12.

[0074] Moreover, when the opening / closing part 35 is provided on the short side 30 on the side opposite to the frame 11, the frame 11 will interfere when the cover 18 is attached and detached with the bed 12 installed on the frame 11. In contrast, according to the technology of the present invention, as Figure 3 and Figure 4 shown, the opening / closing part 35 is provided on the short side 29 on the frame 11 side. Therefore, when the cover 18 is attached and detached, the frame 11 does not interfere, so that the cover 18 can be attached and detached smoothly. Also, the opening / closing part 35 is not conspicuous under the shadow of the frame 11, so the user will not be aware of the opening / closing part 35.

[0075] In the present embodiment, the base portion is the caster portion 16 to which the casters 19 are attached. Therefore, the bed 12 can be freely moved within the medical facility. In addition, the base portion is not limited to the caster portion 16 to which the casters 19 are attached, and may be the original base portion without the casters 19 attached.

[0076] As Figure 1 shown, the bed 12 is a so-called docking type bed that is detachably connected to the frame 11. Therefore, it can be used as follows: The bed 12 is moved into the ward, the subject is moved from the bed in the ward to the top plate 15 of the bed 12, and the bed 12 with the subject lying on the top plate 15 is moved into the imaging room of the MRI apparatus 10 for imaging. In addition, the bed is not limited to the exemplified docking type bed, and may be a fixed bed that is non-detachably connected to the frame 11.

[0077] In addition, as the detachable member, the hook-and-loop fastener 42 is exemplified, but it is not limited thereto. As an example, as Figure 9 shown, a linear zipper 55 can be used instead of the hook-and-loop fastener 42. The linear zipper 55 is as easy to attach and detach as the hook-and-loop fastener 42. And in the case of the hook-and-loop fastener 42, depending on the installation method, there is a possibility that one end 40 and the other end 41 are offset in the vertical direction, but this is not possible with the linear zipper 55.

[0078] In addition, in Figure 9 , one end 40 is not overlapped with the other end 41 and the other end 41 is not covered with one end 40. Thus, it is not necessary to overlap one end 40 with the other end 41 and cover the other end 41 with one end 40. Of course, in Figure 9 , one end 40 and the other end 41 can also be overlapped and the other end 41 can be covered with one end 40.

[0079] Similarly, in Figure 9 , one end 50 of the frame member 26 is not fitted with the other end 51. Thus, it is not necessary to fit one end 50 of the frame member 26 with the other end 51. At least at the opening / closing portion 35, the one end 40 and the other end 41 of the cover sheet 25 facing each other are detachably connected by a detachable member such as the hook-and-loop fastener 42 and the linear zipper 55. Of course, in Figure 9 , one end 50 of the frame member 26 can also be fitted with the other end 51.

[0080] And it is exemplified that at the bending portion 37, the frame member 26 is separated and only connected by the cover sheet 25, but it is not limited thereto. As an example, as Figure 10 shown, at the bending portion 37, the frame member 26 can be separated and connected by a rubber hose 60. The rubber hose 60 is an example of the "flexible connecting member" related to the technology of the present invention. According to this structure, compared with the case where the frame member 26 is separated and only connected by the cover sheet 25, the strength of the bending portion 37 can be improved.

[0081] The frame member 26 is detachably connected by fitting one end 50 and the other end 51 that face each other at the opening / closing portion 35, but it is not limited thereto. As an example, as Figure 11 shown, the one end 50 and the other end 51 can be detachably connected by a clip 65.

[0082] Or, as an example, as Figure 12 shown, the one end 50 and the other end 51 can also be detachably connected by a locking engagement portion 70. The locking engagement portion 70 is composed of a cylindrical protrusion 71 provided on the circumferential surface of the one end 50 and a rectangular engagement portion 72 mounted on the other end 51. A semi-elliptical notch 73 that engages with the protrusion 71 is formed in the engagement portion 72. According to the locking engagement portion 70, it is less likely to come off compared to the method of fitting the one end 50 and the other end 51. Also, according to the locking engagement portion 70, it does not become bulky compared to the clip 65.

[0083] As the portion where the opening / closing portion 35 is provided, the short side 29 is exemplified, but it is not limited thereto. The opening / closing portion 35 can also be provided on the opposite short side 30. And, as an example, as Figure 13 shown in the cover 75, the opening / closing portion 35 can be provided on the long side 32. In this case, the bending portion 37 is provided at a portion of the long side 31 that faces the opening / closing portion 35. Here, when the opening / closing portion 35 and the bending portion 37 are provided on the long sides 32 and 31, it is also preferable to set them close to the side of the frame 11 as Figure 13 shown in consideration of the easy detachability of the cover 18.

[0084] When the opening / closing portion 35 is provided on the long side 32, the opening width of the opening / closing portion 35 can be reduced compared to the case where the opening / closing portion 35 is provided on the short side 29 or 30. Moreover, even with such a small opening width, the cover 18 can be easily attached and detached. And the method of providing the opening / closing portion 35 on the long side 32 is suitable for the case where there is space in the front and back of the bed 12. Additionally, the opening / closing portion 35 can be provided on the long side 31 and the bending portion 37 can be provided on the long side 32.

[0085] Furthermore, as an example, as Figure 14As in the case of the cover 80 shown, an opening / closing portion 35 may also be provided at the corner of the short side 29 and the long side 31. In this case, the bending portion 37 is provided at the corner of the short side 30 and the long side 32 facing the opening / closing portion 35. According to this structure, compared with the cases of providing the opening / closing portion 35 on the short side 29 or 30 and the cases of providing the opening / closing portion 35 on the long side 31 or 32, the opening width of the opening / closing portion 35 can be further increased, so that the cover 18 can be more easily loaded and unloaded. Moreover, the method of providing the opening / closing portion 35 at the corner is suitable for the case where there is space on the left and right of the bed 12. Furthermore, the method of providing the opening / closing portion 35 at the corner is suitable for the case where the lifting mechanism 17 is relatively large and the opening width cannot be avoided without being made larger to avoid the lifting mechanism 17.

[0086] Moreover, as an example, as Figure 15 shown in the cover 85, the opening / closing portions 35 may be provided respectively at approximately the centers of the long sides 31 and 32. In other words, the cover 85 can be divided into front and rear two parts. In this case, the bending portion 37 is not required. According to this structure, when transporting a new cover 85 from the factory to the medical facility as a substitute for the contaminated and / or damaged cover 85, it is easy to handle. And when storing the cover 85 in the factory or the medical facility, it does not occupy space. In addition, instead of or in addition to the centers of the long sides 31 and 32, the opening / closing portion 35 may be provided at the center of the short side 29 and / or 30. And it is not limited to the center of the side, and a plurality of opening / closing portions 35 may be provided at any position.

[0087] As an example, as Figure 16 shown in the cover 90, it may be as follows: the opening / closing portion 35 is provided on the short side 29, but the bending portion 37 is provided on the long side 31 instead of the short side 30. In short, as long as the bending portion 37 is a portion that can make the opening / closing portion 35 easy to open, it does not need to be provided at the portion facing the opening / closing portion 35, and the bending portion 37 is not limited to one.

[0088] As a loading and unloading member, buttons such as four-hole buttons, snap buttons, and magnetic buttons can be used instead of the exemplified hook-and-loop fastener 42 and linear zipper 55, and hooks such as key hooks and spring hooks can also be used. The hook-and-loop fastener 42 can be used in combination with buttons or hooks, or buttons and hooks. Among them, although the magnetic button is easy to load and unload, it may be adsorbed on the frame 11. Therefore, in the case where the medical image photographing apparatus is the MRI apparatus 10, it should be considered carefully.

[0089] As a connection method between one end 50 and the other end 51 of the frame member 26 at the opening / closing portion 35, instead of Figure 7 the fitting shown, Figure 11 the clip 65 shown, and Figure 12The latching engagement portion 70 shown is a method in which magnets are installed at one end 50 and the other end 51, and the one end 50 and the other end 51 are connected by these magnets. However, in this case, since the magnets may also be attracted to the frame 11, when the medical image photographing apparatus is the MRI apparatus 10, this method should be considered carefully.

[0090] As the structure of the bending portion 37, it is possible to replace Figure 8 the structure in which the frame member 26 shown is cut off and only connected by the cover sheet 25 and Figure 10 the structure in which the frame member 26 shown is cut off and connected by the rubber hose 60, and instead adopt a structure in which the cut-off frame members 26 are connected to each other by a hinge. When using a hinge, the strength of the bending portion 37 can be improved compared to the case of the rubber hose 60. However, the structure is more complex and expensive than that of the rubber hose 60.

[0091] The cut 36 can be an inclined straight line shape, a stepped shape, or a square wave shape or a sawtooth wave shape in which periodic unevenness repeats.

[0092] The cover can be composed only of the cover sheet 25 without the frame member 26. That is, the cover can be a structure other than a bellows structure.

[0093] As the medical image photographing apparatus, the MRI apparatus 10 is exemplified, but it is not limited thereto. It can also be a CT apparatus, a PET (Positron Emission Tomography) apparatus, a SPECT (Single Photon Emission Computed Tomography) apparatus, etc.
