[0008] (First embodiment) A first embodiment will be described. Fig. 1 is a front view of an X-ray diagnostic apparatus 100 to which an installation jig 1 of the first embodiment is attached. Fig. 2 is a side view of the X-ray diagnostic apparatus 100. Fig. 3 is an overall perspective view of the installation jig 1. Fig. 4 is an enlarged perspective view of a rotating part 114. As shown in Figs. 1 and 2, the X-ray diagnostic apparatus 100 includes, for example, a gantry 110, a joint frame 120, a body 130, and a tube stand 140.

[0009] The gantry 110 includes, for example, a housing 112 and a rotating part 114. The housing 112 is, for example, box-shaped. The gantry 110 is, for example, fixed to a floor surface by the housing 112 standing upright. The gantry 110 is an example of an installed object. The housing 112 supports a body 130 via a joint frame 120. The housing 112 supports a tube stand 140 via the joint frame 120 and the body 130.

[0010] The swivel unit 114 is housed in the housing 112 with a portion of it exposed from the side of the housing 112. As shown in Figs. 1 and 2, the swivel unit 114 includes a swivel ring 115 and a motor 116. The swivel ring 115 is a thin, flat, ring-shaped member. The motor 116 is provided, for example, in the vicinity of the swivel ring 115. The swivel ring 115 can be rotated by the motor 116. As shown in Figs. 3 and 4, the swivel ring 115 is provided with a plurality of engaged holes 117. The engaged holes 117 are distributed over a wide range in the circumferential direction of the swivel ring 115. The engaged holes 117 are an example of an engaged portion.

[0011] As shown in FIG. 2, the joint frame 120 includes, for example, a vertical portion 122 and a horizontal portion 124. The vertical portion 122 is a plate-shaped member extending in the vertical direction. The horizontal portion 124 is a plate-shaped member extending in the horizontal direction. The horizontal portion 124 is connected to the lower end of the vertical portion 122. As shown in FIGS. 3 and 4, the vertical portion 122 is provided with a plurality of engaging holes 125 arranged to face the engaged holes 117. The engaging holes 125 provided in the vertical portion 122 and the engaged holes 117 provided in the swivel ring 115 are fastened with bolts and nuts to fasten the swivel ring 115 and the vertical portion 122. The joint frame 120 is fixed to the swivel portion 114 by fastening the swivel ring 115 and the vertical portion 122 with bolts and nuts.

[0012] 2, the body 130 is fixed to the top surface of the tip of the horizontal section 124 by fasteners such as bolts and nuts (not shown). The joint frame 120 and the body 130 are configured as separate bodies, but the two may also be configured as one body. The joint frame 120 may also be configured as one body with the slewing ring 115.

[0013] The body 130 is a bed that can be raised or lowered from a vertical state to a horizontal state by the operation of the swivel unit 114. The body 130 supports a subject undergoing an X-ray examination. The body 130 has a rectangular parallelepiped shape. When the body 130 is disposed, for example, extending in the horizontal direction, the body 130 supports the subject by placing the subject on the body 130. When the body 130 is disposed, for example, extending in the vertical direction, the body 130 supports the subject on the side of the subject.

[0014] A vertically movable frame 132 is attached to the side of the body 130. A rail (not shown) is provided on the side of the body 130. The vertically movable frame 132 is capable of moving along the side of the body 130, guided by the rail. When the body 130 is disposed in the vertical direction, the vertically movable frame 132 is capable of moving up and down.

[0015] A tube stand 140 is mounted on the vertically movable frame 132. The tube stand 140 is equipped with an X-ray tube. The tube stand 140 is disposed so as to protrude toward the body 130 when viewed from the housing 112 side. The tube of the tube stand 140 irradiates an object supported by the body 130 with X-rays.

[0016] The X-ray diagnostic apparatus 100 is installed and used, for example, in a medical examination room. When the X-ray diagnostic apparatus 100 is installed, for example, the gantry 110 is first erected and fixed to the floor of an examination room. Next, the body 130 is attached to the gantry 110 via the joint frame 120. Then, the tube stand 140 is mounted on the vertical movement frame 132 of the body 130, and the installation of the X-ray diagnostic apparatus 100 is completed.

[0017] The installation jig 1 is used in the process of installing the X-ray diagnostic apparatus 100. In the embodiment, the installation jig 1 is attached to the rotating part 114 of the gantry 110 and used in the process of mounting the tube stand 140 on the vertically movable frame 132. The installation jig 1 in the state where it is attached to the rotating part 114 of the gantry 110 will be described below.

[0018] 1 and 3, installation jig 1 includes, for example, an engagement portion 10 and a hanging portion 20. Engagement portion 10 is engaged with swivel portion 114 of gantry 110. When attached to swivel portion 114, engagement portion 10 is provided so as to protrude toward body 130 beyond the surface of swivel portion 114 on which body 130 is provided.

[0019] 3 and 4, the engagement portion 10 includes, for example, a right frame 11, a left frame 12, and a lower frame 13. The right frame 11 and the left frame 12 are both elongated members having a substantially rectangular cross section and are hollow. The right frame 11 and the left frame 12 are arranged in a horizontal direction, facing in a direction intersecting, for example, perpendicular to, the direction in which the body 130 extends.

[0020] A right mounting plate 11P and a left mounting plate 12P are fixed to the side ends of the right frame 11 and the left frame 12, respectively. The right mounting plate 11P and the left mounting plate 12P are both disposed substantially parallel to the swivel ring 115. An engagement hole 11H is provided in the right mounting plate 11P. Similarly, an engagement hole 11H is provided in the left mounting plate 12P. The engagement hole 11H provided in the right mounting plate 11P and the engagement holes provided in the left mounting plate 12P are fastened to a plurality of engaged holes 117 provided in the swivel ring 115 with bolts and nuts, thereby fastening the swivel ring 115 to the right frame 11 and the left frame 12.

[0021] The lower frame 13 includes, for example, a base plate 14, a right leg frame 15, and a left leg frame 16. The base plate 14 is disposed along a plane direction and has a rectangular shape in a plan view. The right frame 11 and the left frame 12 are placed on and fixed to the top surface of the base plate 14.

[0022] The right leg frame 15 is disposed on the lower right side of the base plate 14, and the left leg frame 16 is disposed on the lower left side. The right leg frame 15 is provided with a lower right mounting plate 15P and a right bottom plate 15B, and the left leg frame 16 is provided with a lower left mounting plate 16P and a left bottom plate 16B. The lower right mounting plate 15P and the lower left mounting plate 16P are both disposed approximately parallel to the vertical portion 122 of the joint frame 120.

[0023] The right bottom plate 15B and the left bottom plate 16B are provided continuous with one end side of the lower right mounting plate 15P and the lower left mounting plate 16P, respectively. The right bottom plate 15B and the left bottom plate 16B intersect, for example, perpendicular to the lower right mounting plate 15P and the lower left mounting plate 16P, respectively, and are arranged along a horizontal plane. A right flange 15J is raised from the side of the right bottom plate 15B opposite to the side connected to the lower right mounting plate 15P. A left flange 16J is raised from the side of the left bottom plate 16B opposite to the side connected to the lower left mounting plate 16P.

[0024] The lower right mounting plate 15P and the lower left mounting plate 16P are provided with engagement holes 15H, 16H, respectively. The engagement holes 15H, 16H provided in the lower right mounting plate 15P and the lower left mounting plate 16P and a plurality of engaged holes 117 provided in the vertical portion 122 of the joint frame 120 are fastened with bolts and nuts to fasten the swivel ring 115 to the right leg frame 15 and the left leg frame 16 via the joint frame 120. The installation jig 1 is fixed to the swivel portion 114 by fastening the swivel ring 115 to the right frame 11, the left frame 12, the right leg frame 15, and the left leg frame 16 with bolts and nuts, respectively.

[0025] A right pedestal 15D is provided at the left end of the right bottom plate 15B. A left pedestal 16D is provided at the right end of the left bottom plate 16B. A right reinforcing plate 15F is provided above the right pedestal 15D. The right reinforcing plate 15F is a plate-like member that is substantially in the shape of a right-angled triangle in side view. One of the two sides of the right reinforcing plate 15F that sandwich the right angle is arranged along the bottom surface of the base plate 14, and the other side is arranged along the surface of the right lower mounting plate 15P that faces the body 130.

[0026] A left reinforcing plate 16F is provided above the left pedestal 16D. The left reinforcing plate 16F is a plate-like member that is shaped like a substantially right-angled triangle in side view. One of the two sides of the left reinforcing plate 16F that sandwich the right angle is disposed along the bottom surface of the base plate 14, and the other side is disposed along the surface of the left lower mounting plate 16P that faces the body 130.

[0027] The suspension part 20 includes, for example, a suspension frame 21, a pair of eye bolts 22, and a pair of chain blocks 23. The suspension frame 21 is a rod-shaped member extending horizontally along the extension direction of the body 130. The two eye bolts 22 are fixed to the tip of the suspension frame 21 at positions spaced apart from each other in the longitudinal direction of the suspension frame 21.

[0028] A pair of chain blocks 23 is suspended from a pair of eye bolts 22. The chain blocks 23 are suspended from the ends of the suspension frames 21. The chain blocks 23 include a pulley unit 24 and a chain 25. The pulley unit 24 is suspended directly from the eye bolts 22. The chain 25 is reeled out from the lower end of the pulley unit 24 and suspended.

[0029] The chain block 23 is a so-called manual type in which the chain 25 (chain block 23) can be moved up and down by human power. The chain block 23 may be an electric type, for example, in which the pulley section 24 is provided with a motor that moves the chain block 23 up and down. The motor is an example of a drive source. The chain block 23 may be available as both an electric type and a manual type in which the chain 25 can be moved up and down by either human power or a motor. The drive source may be something other than an electric motor, for example, a hydraulic type.

[0030] When mounting tube stand 140, eye bolt 142 is attached to the side of tube stand 140. Chain block 23 holds tube stand 140 by hooking hook 26 onto eye bolt 142. Suspension unit 20 operates pulley unit 24 to move hook 26 up and down, thereby moving tube stand 140 held by chain block 23 up and down.

[0031] Suspension part 20 suspends tube stand 140 from above the position where vertically movable frame 132 in X-ray diagnostic apparatus 100 is arranged. Chain 25 can be reeled out and wound up by pulley part 24, so that suspension part 20 can adjust the height of tube stand 140. Tube stand 140 is an example of an object to be installed. The position where vertically movable frame 132 is arranged is an example of an installation target position.

[0032] The suspension part 20 further includes a connection frame 27, an upper reinforcing member 28, and a lower reinforcing member 29, as shown in FIGS.

[0033] The connection frame 27 is a hollow, elongated member extending in the vertical direction. The connection part 30 is erected at a position sandwiched between the right frame 11 and the left frame 12 on the base plate 14 of the engagement part 10 protruding from the gantry 110. The connection frame 27 may be solid.

[0034] The upper reinforcing member 28 includes, for example, a first reinforcing plate 28A and a second reinforcing plate 28B. The first reinforcing plate 28A and the second reinforcing plate 28B are both elongated plate materials. One end of the first reinforcing plate 28A is fixed to a position on the side facing the gantry 110 at approximately the center position in the longitudinal direction of the suspension frame 21. The other end of the first reinforcing plate 28A is fixed to a position on the side facing the gantry 110 at approximately the center position in the longitudinal direction of the connection frame 27.

[0035] One end of second reinforcing plate 28B is fixed to a position on the opposite side of hanging frame 21 from the side facing gantry 110 at approximately the center in the longitudinal direction of hanging frame 21. The other end of second reinforcing plate 28B is fixed to a position on the opposite side of connecting frame 27 from the side facing gantry 110 at approximately the center in the longitudinal direction of connecting frame 27. Both first reinforcing plate 28A and second reinforcing plate 28B are disposed at an angle with respect to the vertical direction.

[0036] 4, the lower reinforcing member 29 includes, for example, a reinforcing flat plate 29A, a first lower reinforcing plate 29B, and a second lower reinforcing plate 29C. The reinforcing flat plate 29A has a substantially rectangular shape in a plan view, and is placed on the right frame 11 and the left frame 12. The connecting frame 27 penetrates the reinforcing flat plate 29A and is erected on the base plate 14.

[0037] The first lower reinforcing plate 29B and the second lower reinforcing plate 29C are formed by connecting two elongated flat plate members so as to form a generally inverted V shape when viewed from the front. The first lower reinforcing plate 29B is disposed on the opposite side of the connection frame 27 as viewed from the gantry 110. The second lower reinforcing plate 29C is disposed on the gantry 110 side of the first lower reinforcing plate 29B. The first lower reinforcing plate 29B and the second lower reinforcing plate 29C are both erected on the reinforcing flat plate 29A. The first lower reinforcing plate 29B and the second lower reinforcing plate 29C support the connection frame 27 from the gantry 110 side and the opposite side of the gantry 110, respectively.

[0038] Next, an example of an installation method of the X-ray diagnostic apparatus 100 using the installation jig 1 will be described. Fig. 5 is a flow chart showing an example of an installation procedure of the X-ray diagnostic apparatus 100. When the X-ray diagnostic apparatus 100 is installed in an examination room, first, the gantry 110 is set upright on the floor of the examination room (step S101). In the gantry 110, the swivel ring 115 of the swivel part 114 is exposed.

[0039] Next, installation jig 1 is attached to swivel ring 115 (step S103). After installation jig 1 is attached to swivel ring 115, tube stand 140 is placed on the floor surface on the side of vertically movable frame 132. Next, chain block 23 is positioned directly above tube stand 140 with eyebolts 142 attached to both sides (step S105). Then, chain 25 of chain block 23 is unwound from pulley portion 24, and the unwound length of chain 25 becomes longer (step S107).

[0040] When the length of the chain 25 that has been let out becomes longer than the distance between the pulley unit 24 and the eyebolt 142, the letting out of the chain 25 is completed. Then, the hook 26 attached to the lower end of the chain 25 is hooked onto the eyebolt 142 attached to the tube stand 140 placed on the floor surface, and the tube stand 140 is held by the chain block 23 (step S109). At this time, the chain 25 is in a slack state, so that the chain 25 is not stretched when the hook 26 is hooked onto the eyebolt 142.

[0041] Once hook 26 is hooked onto eyebolt 142, chain 25 is pulled manually to rotate pulley unit 24 and wind up chain 25 (step S111). Chain 25 is manually wound up via pulley unit 24, gradually going from a slack state to a taut state. By continuing to pull chain 25 manually, tube stand 140 is suspended and raised by chain 25 (step S113).

[0042] In this state, tube stand 140 is raised to a height higher than the height position of body 130 attached to gantry 110. When tube stand 140 has been raised to this position, the manual pulling of chain 25 is stopped, and chain 25 is manually held to prevent pulley section 24 from rotating, so that tube stand 140 is suspended from hanging section 20. In this way, tube stand 140 is held in a position that does not interfere with body 130 when body 130 is attached to swivel ring 115.

[0043] Next, joint frame 120 is fixed to swivel ring 115, and body 130 is fixed to joint frame 120. Thus, body 130 is attached to gantry 110 via joint frame 120 (step S115). Installation jig 1 is designed so that vertical movement frame 132 of body 130 attached to gantry 110 is located directly below tube stand 140 suspended by chain 25. Then, while an operator holds chain 25, tube stand 140 is slowly lowered by its own weight, and tube stand 140 is placed on vertical movement frame 132 (step S117). Then, tube stand 140 is fixed to vertical movement frame 132.

[0044] After the tube stand 140 is fixed to the vertically movable frame 132, or during the operation of fixing the tube stand 140 to the vertically movable frame 132, the installation jig 1 is removed from the rotating part 114 of the gantry 110. Then, the tube stand 140 is fixed to the vertically movable frame 132, and the installation jig 1 is removed from the gantry 110 (step S119). In this way, the installation operation of the X-ray diagnostic apparatus 100 is completed.

[0045] Tube stand 140 is a heavy object. For this reason, conventionally, when installing tube stand 140 on gantry 110, if the examination room in which X-ray diagnostic apparatus 100 is installed is large, tube stand 140 is suspended from a scaffold, for example. However, if the examination room is small, it is difficult to build a scaffold, so tube stand 140 has to be lifted to the height of body 130 by hand, for example, which places a heavy burden on workers. Even if the examination room is large and a scaffold can be built, it is time-consuming to build the scaffold, which requires a lot of manpower and effort.

[0046] In this regard, in the first embodiment, when the X-ray diagnostic apparatus 100 is installed on the floor of an examination room, the tube stand 140 is suspended using the installation jig 1 and fixed to the vertically movable frame 132. This reduces the labor required to install the tube stand 140 on the vertically movable frame 132, and reduces the labor required to install the X-ray diagnostic apparatus 100.

[0047] Since the tube stand 140 suspended by the installation jig 1 is heavy, a large force is applied to the installation jig 1 suspending the tube stand 140. This force acts to tip over the connection part 30 or to bend the engagement part 10. In this regard, the connection part 30 is reinforced by an upper reinforcing member 28 and a lower reinforcing member 29. Furthermore, the engagement part 10 is reinforced by a right reinforcing plate 15F and a left reinforcing plate 16F. Therefore, when the installation jig 1 suspends the tube stand 140, it is possible to prevent the connection part 30 from tipping over or the engagement part 10 from being bent.

[0048] Second embodiment A second embodiment will be described. Fig. 6 is a front view of an X-ray diagnostic apparatus 100 to which an installation jig 2 of the second embodiment is attached. In the second embodiment, compared to the first embodiment, the configuration of the X-ray diagnostic apparatus 100 installed in an examination room or the like is the same, but the installation jig 2 is different from the installation jig 1. While the installation jig 1 of the first embodiment is attached to the rotating part 114 of the gantry 110, the installation jig 2 of the second embodiment is attached to the top surface of the gantry 110.

[0049] The installation jig 2 includes, for example, a base plate 40, a suspension frame 41, and a connection frame 42. An engaged hole is provided in the top surface of the gantry 110 in the X-ray diagnostic apparatus 100. An engaging hole is provided in the base plate 40 and is arranged to face the engaged hole provided in the top surface of the gantry 110, and the base plate 40 is fixed to the top surface of the gantry 110 by tightening a bolt that passes through the engaged hole and the engaging hole with a nut. The engaged hole is an example of an engaged portion.

[0050] The suspension frame 41 in the installation jig 2 is a rod-shaped member extending horizontally in the direction in which the body 130 extends. A chain block 23 similar to that in the first embodiment is suspended from the tip of the suspension frame 41. A tube stand 140 is suspended from the chain block 23. A connection frame 42 is disposed between the base plate 40 and the suspension frame 41. The connection frame 42 connects the base plate 40 and the suspension frame 41.

[0051] Next, a description will be given of an example of installation work of the X-ray diagnostic apparatus 100 using the installation jig 2. As in the first embodiment, after the gantry 110 is erected and fixed on the floor of the examination room, the base plate 40 of the installation jig 2 is attached to the top surface of the gantry 110.

[0052] Next, similarly to the first embodiment, tube stand 140 is placed on the floor surface beside vertically movable frame 132, and chain block 23 is placed directly above tube stand 140. Then, chain 25 of chain block 23 is unwound from pulley unit 24, and hook 26 attached to the lower end of chain 25 is hooked onto eyebolt 142 attached to tube stand 140 placed on the floor surface.

[0053] Once hook 26 is hooked onto eyebolt 142, tube stand 140 is raised by manually pulling chain 25 to a height higher than the height of body 130 attached to gantry 110. After that, body 130 is attached to swivel unit 114 via joint frame 120. After that, while an operator holds chain 25, tube stand 140 is slowly lowered by its own weight, and tube stand 140 is placed on top of vertically movable frame 132.

[0054] Thereafter, the tube stand 140 is fixed onto the vertically movable frame 132. After the tube stand 140 is fixed to the vertically movable frame 132, or during the process of fixing the tube stand 140 to the vertically movable frame 132, the installation jig 1 is removed from the gantry 110. In this manner, the installation process of the X-ray diagnostic apparatus 100 is completed.

[0055] In the second embodiment, when the X-ray diagnostic apparatus 100 is installed on the floor of an examination room, the tube stand 140 is suspended using the installation jig 2 and installed on the vertically movable frame 132. This reduces the labor required to install the tube stand 140 on the vertically movable frame 132, and reduces the labor required to install the X-ray diagnostic apparatus 100.

[0056] Furthermore, in the second embodiment, the installation jig 2 is attached to the top surface of the gantry 110. Therefore, the tube stand 140 can be suspended by the installation jig 2 before the body 130 is attached to the swivel unit 114. Therefore, after the body 130 is attached to the swivel unit 114, it can be quickly placed on the vertically movable frame 132 and installed, which contributes to shortening the installation time.

[0057] (Third embodiment) Fig. 7 is a side view of the X-ray diagnostic apparatus 100 to which the installation jig 3 of the third embodiment is attached. Fig. 8 is a partially enlarged perspective view of the suspended body 130. In the third embodiment, compared to the first embodiment, the configuration of the X-ray diagnostic apparatus 100 to be installed in an examination room or the like is the same, but the installation jig 3 is different from the installation jig 1. The installation jig 3 of the third embodiment is attached to the rotating part 114 of the gantry 110 to which the joint frame 120 is not attached. Also, the installation object in the first embodiment is the tube stand 140, but the installation object in the third embodiment is the body 130.

[0058] The installation jig 3 includes a base member 50, a suspension frame 51, and a connection frame 52. The base member 50 is provided with an engagement hole disposed opposite an engaged hole provided in the swivel part 114. The base member 50 is fixed to the swivel part 114 of the gantry 110 by tightening a bolt passing through the engaged hole and the engagement hole with a nut. The engaged hole through which the bolt passes together with the engagement hole is an engaged hole other than the engaged hole in the swivel part 114 to which the joint frame 120 is to be attached.

[0059] The hanging frame 51 in the installation jig 3 is a rod-shaped member that extends horizontally in a direction that intersects, for example, perpendicular to, the direction in which the body 130 extends. A connection frame 52 is disposed between the base member 50 and the hanging frame 51. The connection frame 52 connects the base member 50 and the hanging frame 51.

[0060] A chain block 54 is suspended from the tip of the suspension frame 51. The chain block 54 includes a pulley section 54A and four chains 54B (only three are shown in FIG. 7) that are reeled out from the pulley section 54A. A hook 54C is attached to the lower end of the chain 54B of the chain block 54, as shown in FIG.

[0061] A suspended plate 55 is fixed to each of the four side surfaces of the body 130, which is the object to be installed. A suspended hook 55A is provided on the suspended plate 55. A hook 54C attached to the lower end of one of the four chains 54B of the chain block 54 is hooked onto the suspended hook 55A.

[0062] Similar to the above-mentioned one side surface, suspended plates 55 are fixed to the other three side surfaces of the four side surfaces of the body 130. Hooks 54C attached to the lower ends of the other three of the four chains 54B are also hooked onto suspended hooks 55A fixed to the other three side surfaces of the body 130, similar to the above-mentioned hooks 54C.

[0063] Next, an example of installation work of the X-ray diagnostic apparatus 100 using the installation jig 3 will be described. As in the first embodiment, after the gantry 110 is fixed to the floor surface of the examination room, the base member 50 of the installation jig 3 is attached to the rotating part 114 of the gantry 110. Then, the joint frame 120 is attached to the rotating part 114. The joint frame 120 may be attached to the body 130 instead of being attached to the rotating part 114.

[0064] Next, the body 130 is placed on the floor surface to the side of the gantry 110, and the chain block 54 is placed directly above the body 130. Then, the chain 54B of the chain block 54 is let out from the pulley part 54A, and the hook 54C attached to the lower end of the chain 54B is hooked onto the suspended hook 55A of the suspended plate 55 fixed to the body 130 placed on the floor surface.

[0065] Once hook 54C is hooked onto suspended hook 55A of suspended plate 55, chain 54B is pulled manually to rotate the pulley of pulley section 54A, and body 130 is raised by chain 54B to a height position at which it can be connected to joint frame 120. After that, body 130 is connected to joint frame 120.

[0066] Next, the installation jig 3 is removed from the rotating part 114. At the same time, for example, by using another lifting mechanism or by using manpower by constructing a scaffold, the tube stand 140 (FIG. 1) is lifted and placed on the vertically movable frame 132. In this way, the installation work of the X-ray diagnostic apparatus 100 is completed.

[0067] In the third embodiment, when the X-ray diagnostic apparatus 100 is installed on the floor of an examination room, the body 130 is suspended using the installation jig 2 and fixed to the joint frame 120. This reduces the labor required to install the body 130 on the joint frame 120, and reduces the labor required to install the X-ray diagnostic apparatus 100.

[0068] In the third embodiment, the body 130 is suspended by the installation jig 3 attached to the swivel unit 114, but as in the second embodiment, the body 130 may be suspended by using the installation jig 2 attached to the top surface of the gantry 110. In this case, the tube stand 140 may be suspended by the installation jig 2 after the body 130 is attached to the gantry 110.

[0069] In the above embodiments, the installation jigs 1 to 3 have been described, but the first to third embodiments may be appropriately combined. For example, in the third embodiment, the installation jig 3 may be attached to the swivel part 114 of the gantry 110 to suspend the body 130, and the installation jig 2 of the second embodiment may be attached to the top surface of the gantry 110 to suspend the tube stand 140. When the body 130 and the tube stand 140 are suspended by the installation jigs 1 to 3, a member for preventing the gantry 110 from falling over may be provided. The member for preventing the fall over may be, for example, a support that supports the housing 112 from the side of the gantry 110 where the swivel part 114 is provided.

[0070] In the above embodiment, the hanging part 20 in the installation jig 1 is fixed to the connection part 30, but the hanging part 20 may be movable relative to the connection part 30, allowing the horizontal position of the tube stand 140 to be adjusted. For example, the hanging part 20 may be extendable, with its base end fixed to the connection part 30 and its tip moving away from or toward the base end to adjust its position. The connection part 30 is fixed to the engagement part 10, but the connection part 30 may be movable relative to the engagement part 10. For example, the connection part 30 may be one in which the connection frame 27 rotates around a vertical axis, or the connection part 30 may move horizontally at the engagement part 10 to allow the position of the tube stand 140 to be adjusted.

[0071] According to at least one of the embodiments described above, the installation labor of the X-ray diagnostic apparatus can be reduced by having an engagement portion that engages with an object fixed as part of the X-ray diagnostic apparatus, and a hanging portion that extends from the engagement portion and suspends an object to be installed in the X-ray diagnostic apparatus based on information about the position of the object to be installed.

[0072] Although some embodiments have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope of the invention and its equivalents as described in the claims, as well as in the scope and spirit of the invention.
