Next, the structure of the table 3 will be described in detail.

FIG. 2 is an explanatory diagram of the structure of the table 3.
FIG. 2A is a perspective view of the table 3, and FIG. 2B is an exploded perspective view of the table 3.
The table 3 includes a cradle 31 that supports the subject 13 and a cradle support base 32 that supports the cradle 31.

FIG. 3 is a view showing the cradle support base 32.
FIG. 3A is a perspective view of the cradle support base 32, and FIG. 3B is a side view of the cradle support base 32.

  The cradle support base 32 includes a column portion 33, a fixed support member 34, a movable support member 35, a movable support member 36, and the like.

  The support members 34 to 36 are connected by connection members 37 and 38 so as to be aligned in the z direction. The fixed support member 34 is fixed to the column 33, and the movable support members 35 and 36 are connected to the fixed support member 34 by connection members 37 and 38, respectively. The connection member 37 connects the fixed support member 34 and the movable support member 35 to each other so that the movable support member 35 can move in the P direction (see FIG. 3B) with respect to the fixed support member 34. . The connection member 38 connects the fixed support member 34 and the movable support member 36 to each other so that the movable support member 36 can move in the Q direction with respect to the fixed support member 34. As the connection members 37 and 38, for example, an articulated link can be used. In the first embodiment, the fixed support member 34 and the movable support member 35 are connected to each other using one connection member 37, and further, the fixed support member 34 and the movable support member are used using one connection member 38. 36 are connected to each other. However, the fixed support member 34 and the movable support member (35 or 36) may be connected to each other using a plurality of connection members.

  The cradle support base 32 includes cylinders 39 and 40. The cylinder 39 is for rotating the movable support member 35 in the P direction with respect to the fixed support member 34, and the cylinder 40 is for rotating the movable support member 36 in the Q direction with respect to the fixed support member 34. Is. The movable support members 35 and 36 can be rotated with respect to the fixed support member 34 by expansion and contraction of the cylinders 39 and 40 (see FIG. 4).

FIG. 4 is an explanatory diagram when the movable support member 35 is rotated with respect to the fixed support member 34.
FIG. 4A is a view before the movable support member 35 is rotated.
Before the movable support member 35 rotates, the movable support member 35 is held horizontally with respect to the fixed support member 34. When the cylinder 39 extends from the state shown in FIG. 4A, the movable support member 35 rotates upward with respect to the fixed support member 34. FIG. 4B shows a state in which the movable support member 35 is rotated upward due to the extension of the cylinder 39.

  On the other hand, when the cylinder 39 is contracted, the movable support member 35 rotates downward with respect to the fixed support member 34. FIG. 4C shows a state where the movable support member 35 is rotated downward due to the contraction of the cylinder 39.

  Although FIG. 4 illustrates the case where the movable support member 35 is rotated with respect to the fixed support member 34, the case where the movable support member 36 is rotated with respect to the fixed support member 34 can be similarly described. Therefore, the movable support member 36 can also be rotated upward and downward with respect to the fixed support member 34 by expansion and contraction of the cylinder 40. FIG. 5 shows an example of the shape of the cradle support base 32 when the movable support members 35 and 36 are rotated with respect to the fixed support member 34. FIG. 5A shows the shape of the cradle support base 32 when the movable support member 35 is rotated upward with respect to the fixed support member 34 and the movable support member 36 is rotated downward with respect to the fixed support member 34. An example is shown. On the other hand, FIG. 5B shows the cradle support base 32 when the movable support member 35 is rotated downward relative to the fixed support member 34 and the movable support member 36 is rotated upward relative to the fixed support member 34. An example of the shape is shown.

  Thus, the angle θa formed between the fixed support member 34 and the movable support member 35 and the angle θb formed between the fixed support member 34 and the movable support member 36 can be changed. Next, the structure of the cradle 31 will be described.

FIG. 6 is an explanatory diagram of the structure of the cradle 31. FIG. 6A is a perspective view of the cradle 31, and FIG. 6B is an exploded perspective view of the cradle 31.
The cradle 31 has a cradle base 311 and a pad 312.

FIG. 7 is a top view and a side view of the cradle base 311.
The cradle base 311 has three plates 311a, 311b, and 311c. The plate 311a and the plate 311b are connected by a connecting member 311d. The connecting member 311d connects the plates 311a and 311b to each other so that the plate 311b can move in the arrow P direction with respect to the plate 311a. As the connection member 311d, for example, an articulated link can be used.

  The plate 311a and the plate 311c are connected by a connection member 311e. The connecting member 311e connects the plates 311a and 311c to each other so that the plate 311c can move in the arrow Q direction with respect to the plate 311a. As the connecting member 311e, an articulated link can be used similarly to the connecting member 311d.

  FIG. 8 shows an example of the shape of the cradle base 311 when the plates 311b and 311c are moved with respect to the plate 311a.

  FIG. 8A is a side view of the cradle base 311 when the plate 311b is moved upward with respect to the plate 311a and the plate 311c is moved downward with respect to the plate 311a, and FIG. It is a side view of the cradle base 311 when the plate 311b is moved downward relative to the plate 311a and the plate 311c is moved upward relative to the plate 311a.

  As shown in FIG. 8, the cradle base 311 is configured to be able to change the angle θa formed by the plate 311b and the plate 311a and the angle θb formed by the plate 311c and the plate 311a.

  A pad 312 is attached to the surface of the cradle base 311 configured as described above. FIG. 9 is an explanatory diagram of the structure of the pad 312. 9A is a perspective view of the pad 312 and FIG. 9B is a cross-sectional view taken along the line AA of FIG. 9A.

  The pad 312 has a bag body 312a, and a granular body 312b (plastic piece, wood piece, etc.) is accommodated in the bag body 312a. The bag body 312a in which the granular body 312b is stored is used as the pad 312. By attaching the pad 312 to the surface of the cradle base 311, the cradle 31 (see FIG. 6A) is configured. When photographing, the subject 13 sleeps on the pad 312 of the cradle 31.

FIG. 10 is a diagram illustrating a state when the subject 13 is lying on the cradle 31.
10A is a perspective view showing the subject 13 lying on the cradle 31, and FIG. 10B is a cross-sectional view taken along the line AA in FIG. 10B.
When the subject 13 lies on the pad 312, the granular material 312 b in the pad 312 moves due to the pressure received from the subject 13, and the surface of the pad 312 is deformed to conform to the shape of the subject 13. The pad 312 is provided with a valve (not shown) for degassing the air inside the bag body 312a. When the air in the bag body 312a is deaerated, the inside of the bag body 312a is in a vacuum state, so the pad 312 itself becomes hard and the shape is stored. Therefore, the shape of the pad 312 can be maintained so as to follow the shape of the subject 13. Further, when air is injected into the bag body 312a, the vacuum state of the pad 312 is released, so that the pad 312 itself can be softened.

  The cradle 31 is attached to a cradle support base 32. FIG. 11 is a view for explaining how the cradle 31 is attached to the cradle support base 32. The plates 311a, 311b, and 311c of the cradle 31 are positioned on the support members 34, 35, and 36 of the cradle support base 32, respectively. In this way, the table 3 is configured. FIG. 12 shows a perspective view and a side view of the table 3.

  The table 3 configured as described above is designed so that it can be transformed into a chair. Below, a mode when the table 3 deform | transforms into a chair is demonstrated.

FIG. 13 is an explanatory diagram when the table 3 is transformed into a chair.
FIG. 13A is a side view showing the table 3 before being transformed into a chair, and FIG. 13B is a side view showing the table 3 after being transformed into a chair.
When the table 3 is transformed into a chair, first, a sufficient amount of air is injected into the pad 312 of the cradle 31 to make the pad 312 soft.

  After the pad 312 is softened, the cylinder 39 is extended and the cylinder 40 is contracted.

  When the cylinder 39 extends, the movable support member 35 of the cradle support base 32 rotates in the arrow A direction with respect to the fixed support member 34. Since the pad 312 is soft, when the movable support member 35 rotates, the plate 311b located on the movable support member 35 also rotates in the direction of arrow A.

  On the other hand, when the cylinder 40 contracts, the movable support member 36 of the cradle support base 32 rotates in the arrow B direction with respect to the fixed support member 34. Since the pad 312 is soft, when the movable support member 36 rotates, the plate 311c positioned on the movable support member 36 also rotates in the direction of arrow B.

Therefore, as shown in FIG. 13B, the table 3 can be transformed into a chair. In FIG. 13B, the angle of the movable support member 35 is indicated by θa, and the angle of the movable support member 36 is indicated by θb. In FIG. 13B, the cradle 31 can be divided into the following three parts.
(1) Seat surface 31a (portion supported by the fixed support member 34 of the cradle 31)
(2) Backrest 31b (part supported by the movable support member 35 of the cradle 31)
(3) Footrest 31c (part supported by the movable support member 36 of the cradle 31)

  Further, by returning the cylinders 39 and 40 to the original length, the table 3 transformed into a chair can be returned to the original shape (see FIG. 13A).

  In FIG. 13, the movable support member 35 of the table 3 is rotated upward and the movable support member 36 is rotated downward. However, the movable support member 35 of the table 3 is rotated downward and the movable support member 36 is rotated downward. 36 may be rotated upward (see FIG. 14).

  FIG. 14 is a diagram illustrating a state where the movable support member 35 of the table 3 is rotated downward and the movable support member 36 is rotated upward.

  By deforming the table 3 as shown in FIG. 14, the positions of the backrest 31b and the footrest 31c can be reversed with respect to the table 3 of FIG. 13B.

  Next, a flow when the subject 13 is imaged using the table 3 configured as described above will be described.

FIG. 15 is a diagram showing a flow when photographing the subject 13.
In step ST1, the table 3 is transformed into a chair (see FIG. 16).

FIG. 16 is a diagram illustrating a state when the table 3 is transformed into a chair.
The operator operates an operation panel (not shown) of the magnet 2 to transform the table 3 into a chair. Here, the example (refer FIG. 14) which deform | transformed the table 3 so that the part supported by the movable support member 35 of the cradle 31 may become the footrest 31c is shown. The angles of the movable support members 35 and 36 are set to θa and θb, respectively. Air is contained in the pad 312 and is soft. After the table 3 is transformed into a chair, the process proceeds to step ST2.

  In step ST2, the operator sits the subject 13 on the table 3 transformed into a chair (see FIG. 17).

FIG. 17 is a diagram showing a state when the subject 13 sits on the table 3 transformed into a chair.
The operator adjusts the height of the table 3 transformed into a chair to a position where the subject 13 can easily sit down, and causes the subject 13 to sit down. The subject 13 sits down on the seat 31a and leans against the backrest 31b. Since the pad 312 is soft, when the subject 13 sits on the table 3, the particles in the pad 312 move due to the pressure received from the subject 13, and the surface of the pad 312 becomes the shape of the subject 13. Deforms along. Therefore, a comfortable sitting comfort can be provided to the subject 13. After sitting the subject 13, the process proceeds to step ST3.

  In step ST3, the table 3 is deformed so that the cradle 31 has a flat plate shape. FIG. 18 shows a state when the table 3 is deformed so that the cradle 31 has a flat plate shape. The cradle 31 can be formed into a flat plate shape by rotating the movable support members 35 and 36 so that the movable support members 35 and 36 are horizontal with respect to the fixed support member 34. Since the cradle 31 has a flat plate shape, the subject 13 is supported in a horizontal state. While the movable support members 35 and 36 are rotating, the posture of the subject 13 continuously changes, but since the pad 312 of the cradle 31 is soft, the pad 312 is changed according to the change of the posture of the subject 13. The surface of 312 is also deformed so as to follow the shape of the subject 13. Therefore, the cradle 31 can be formed into a flat plate shape without placing a physical burden on the subject 13. After the table 3 is deformed so that the cradle 31 has a flat plate shape, the process proceeds to step ST4.

  In step ST4, the pad 312 is cured. The operator operates the operation panel of the magnet 2 and inputs a signal for extracting air from the pad 312. When this signal is input, the pump 4 removes air from the pad 312. When the air is extracted from the pad 312, the pad 312 itself is cured, so that the shape of the pad 312 can be maintained so as to follow the shape of the subject 13. After the pad 312 is cured, the table 3 is set to a predetermined height so that the cradle 31 can be conveyed into the bore 21. FIG. 19 shows a state after setting the table 3 to a predetermined height. After setting the table 3 to a predetermined height, the process proceeds to step ST5.

  In step ST5, a receiving coil is attached to the imaging region (here, the abdomen) of the subject 13. Then, the cradle 31 is moved in the z direction by the traction device 5 so that the imaging region (abdomen) of the subject 13 reaches the magnet center. FIG. 20 shows a state after the cradle 31 is moved. After the cradle 31 is moved, the subject 13 is scanned.

  In this embodiment, the pad 312 is cured before scanning the subject 13 (step ST4). On the other hand, it is also conceivable to scan the subject 13 without curing the pad 312. It is done. However, when the pad 312 is not cured, there are the following problems (see FIG. 21).

FIG. 21 is an explanatory diagram of a problem when the pad 312 is not cured.
When scanning the subject 13, the cradle 31 may be moved during the scan in order to move the position of the imaging region (in this embodiment, the abdomen). FIG. 21 shows a state where the position of the cradle 31 is moved in the −z direction. When the cradle 31 is moved in the −z direction, the cradle 31 is pushed in the −z direction by the traction device 5. However, since the connection member 311d is configured to bend, if the pad 312 is not cured, the connection member 311d may bend due to the force from the plate 311b. Similarly, when the pad 312 is not cured, the connecting member 311e may be bent. If the connection members 311d and 311e are bent in this manner, the distance Δd between the adjacent plates changes, which may cause a problem that the imaging region cannot be moved to a desired position. Accordingly, it is necessary that the distance Δd between adjacent plates does not change even when the cradle is moved. Therefore, in this embodiment, the pad 312 is cured. When the pad 312 is cured, each plate is fixed relative to the adjacent plate. Therefore, even if the cradle is moved, the distance Δd between adjacent plates can be prevented from changing.
When the scan of the subject 13 is completed, the process proceeds to step ST6.

  In step ST6, the subject 13 is carried out of the bore 21. FIG. 22 shows a state when the subject 13 is carried out from the bore 21. After the subject 13 is carried out of the bore 21, the process proceeds to step ST7.

  In step ST7, the table 3 is lowered. FIG. 23 shows a state when the table 3 is lowered. After lowering the table 3, the process proceeds to step ST8.

  In step ST8, the vacuum state of the pad 312 is released. As a result, air is injected into the pad 312 and the pad 312 becomes soft. After the pad 312 is softened, the process proceeds to step ST9.

  In step ST9, the operator operates the operation panel of the magnet 2 to transform the table 3 into a chair. FIG. 24 shows a state after the table 3 is transformed into a chair. After the table 3 is transformed into a chair, the subject 13 is lowered from the table 3 and the flow is finished.

  In this embodiment, the table 3 can be transformed into a chair by making the pad 312 of the cradle 31 soft. Accordingly, it is possible to reduce the load applied when the subject 13 gets on the table 3 and the load applied when the subject 13 gets off the table 3. Moreover, the burden on the engineer who assists the subject 13 to get on and off the table 3 can be reduced.

  In the above description, after the subject is seated on the table 3 transformed into a chair (see FIG. 17), the table 3 is transformed so that the cradle 31 has a flat plate shape (see FIG. 18). . However, the table 3 may be deformed so that the cradle 31 has a shape different from the flat plate shape. FIG. 25 shows an example in which the table 3 is deformed so that the cradle 31 has a shape different from the flat plate shape. In FIG. 25, the movable support member 35 is horizontal with respect to the fixed support member 34, but the table 3 is deformed so that the movable support member 36 is inclined with respect to the fixed support member 34. Therefore, the cradle 31 supports the lower half of the subject 13 in a horizontal state, but supports the upper half of the subject 13 in an oblique state. After the table 3 is deformed, the pad 312 is cured and the table 3 is set to a predetermined height so that the cradle 31 can be conveyed into the bore 21. FIG. 26 shows a state after setting the table 3 to a predetermined height. After setting the table 3 to a predetermined height, the cradle 31 is moved so that the imaging region of the subject 13 reaches the magnet center. FIG. 27 shows a state after the cradle 31 is moved. After the cradle 31 is moved, the subject 13 is scanned.

  Depending on the health condition of the subject 13, it may be difficult to make the upper body horizontal. In such a case, the upper body of the subject 13 can be raised by deforming the table 3 as shown in FIG. 25, so that the physical burden on the subject 13 can be reduced.

  Further, in the above description, when the table 3 is transformed into a chair, an example is shown in which the side near the magnet 2 of the cradle 31 is the footrest 31c and the side far from the magnet 2 is the backrest 31b (FIG. 17). reference). However, if necessary, the side close to the magnet 2 of the cradle 31 may be the backrest 31b, and the side away from the magnet 2 may be the footrest 31c. FIG. 28 shows an example in which the table 3 is deformed so that the side of the cradle 31 close to the magnet 2 becomes the backrest 31b and the side away from the magnet 2 becomes the footrest 31c. The table 3 is deformed as shown in FIG. 28 by rotating the movable support member 35 upward with respect to the fixed support member 34 while rotating the movable support member 36 downward with respect to the fixed support member 34. be able to. After the table 3 is transformed into a chair, the subject 13 is seated (see FIG. 29), and the table 3 is transformed so that the cradle 31 has a flat plate shape (see FIG. 30). In FIG. 30, since the head of the subject 13 faces the magnet 2 side, the subject 13 is carried into the bore 21 from the head. Thus, the side close to the magnet 2 of the cradle 31 may be the backrest 31b, and the side away from the magnet 2 may be the footrest 31c.

  The movable support member 35 is configured to be able to rotate on both the upper side and the lower side with respect to the fixed support member 34, while the movable support member 36 is also on the upper side and the lower side with respect to the fixed support member 34. It is configured to be able to rotate on both sides. Therefore, since the positions of the backrest 31b and the footrest 31c can be reversed only by controlling the rotation direction of the movable support members 35 and 36, the chair is suitable for transporting the subject from the leg portion to the magnet 2. In addition to being deformed, the subject can be transformed into a chair suitable for transporting the subject from the head to the magnet 2.

(2) Second embodiment The second embodiment is different from the first embodiment in the structure of the cradle, but the other configuration is the same as the first embodiment, and therefore the second embodiment mainly includes the cradle. The structure of will be described.

FIG. 31 is a perspective view of the cradle 50 according to the second embodiment, and FIG. 32 is a top view and a side view of the cradle 50.
The cradle 50 has three plates 51, 52, and 53. The plate 51 and the plate 52 are connected by a connection member 54. The connecting member 54 connects the plates 51 and 52 to each other so that the plate 52 can move relative to the plate 51 in the direction of arrow P (see the side view of FIG. 32). The connecting member 54 is configured to bend. By bending the connecting member 54, the plate 52 can be moved in the P direction (see the side view of FIG. 32) with respect to the plate 51. For the connection member 54, for example, an articulated link can be used.

  The plate 51 and the plate 53 are connected by a connecting member 55. The connecting member 55 connects the plates 51 and 53 to each other so that the plate 53 can move with respect to the plate 51 in the direction of arrow Q (see the side view of FIG. 32). The connecting member 55 is configured to bend. By bending the connecting member 55, the plate 53 can be moved in the Q direction (see the side view of FIG. 32) with respect to the plate 51. As the connection member 54, an articulated link can be used as in the connection member 54.

  In addition, shape memory members 56 and 57 are embedded in the cradle 50. The shape memory member 56 is used as a fixing member for fixing the plate 51 and the plate 52, and the shape memory member 57 is used as a fixing member for fixing the plate 51 and the plate 53. Is. Next, the shape memory members 56 and 57 will be described with reference to FIG.

FIG. 33 is an exploded perspective view of the cradle 50.
Hereinafter, the shape memory member 56 will be described first, and then the shape memory member 57 will be described.

(1) About Shape Memory Member 56 A connecting member 54 and a shape memory member 56 are provided between the plate 51 and the plate 52. The inside of the connecting member 54 is a cavity 54a, and the shape memory member 56 is inserted into the cavity 54a.

  A groove 51a in which the side portion 56c of the shape memory member 56 is embedded is formed on the side surface of the plate 51, and a groove 52a in which the side portion 56d of the shape memory member 56 is embedded is formed on the side surface of the plate 52. Yes.

  The shape memory member 56 has a bag body 56a, and a granular body 56b (plastic piece, wood piece, etc.) is accommodated in the bag body 56a. The bag body 56 a in which the granular body 56 b is stored is used as the shape memory member 56.

  The bag body 56a is provided with a valve (not shown) for degassing the air inside the bag body 56a. When the air in the bag body 56a is degassed, the inside of the bag body 56a is in a vacuum state, so that the shape memory member 56 itself becomes hard and stores its shape. Since the shape memory member 56 is inserted into the cavity 54a of the connection member 54, when the shape memory member 56 becomes hard, the connection member 54 cannot be deformed. Therefore, the plates 51 and 52 can be fixed to each other so that the plate 52 does not move with respect to the plate 51.

  On the other hand, when the vacuum state of the bag body 56a is released, air enters the bag body 56a, so that the shape memory member 56 itself becomes soft. Therefore, since the connecting member 54 can be bent, the plate 52 can be moved in the P direction (see FIG. 32) with respect to the plate 51.

(2) About Shape Memory Member 57 Between the plate 51 and the plate 53, a connection member 55 and a shape memory member 57 are provided. The inside of the connection member 55 is a cavity 55a, and the shape memory member 57 is inserted into the cavity 55a.

  A groove 51b in which the side portion 57c of the shape memory member 57 is embedded is formed on the side surface of the plate 51, and a groove 53a in which the side portion 57d of the shape memory member 57 is embedded is formed on the side surface of the plate 53. Yes.

  The shape memory member 57 has a bag body 57a, and a granular body 57b (plastic piece, wood piece, etc.) is accommodated in the bag body 57a. The bag body 57 a in which the granular body 57 b is stored is used as the shape memory member 57.

  The bag body 57a is provided with a valve (not shown) for degassing the air inside the bag body 57a. When the air in the bag body 57a is deaerated, the inside of the bag body 57a is in a vacuum state, so that the shape memory member 57 itself becomes hard and the shape is stored. Since the shape memory member 57 is inserted into the cavity 55a of the connection member 55, the connection member 55 cannot be deformed when the shape memory member 57 becomes hard. Therefore, the plates 51 and 53 can be fixed to each other so that the plate 53 does not move with respect to the plate 51.

On the other hand, when the vacuum state of the bag body 57a is released, air enters the bag body 57a, so that the shape memory member 57 itself becomes soft. Accordingly, since the connecting member 55 can be bent, the plate 53 can be moved in the Q direction (see FIG. 32) with respect to the plate 51.
The cradle 50 is configured as described above.

  The cradle 50 is attached to the cradle support base 32. FIG. 34 is a view for explaining how the cradle 50 is attached to the cradle support base 32. The plates 51, 52, and 53 of the cradle 50 are positioned on the support members 34, 35, and 36 of the cradle support base 32, respectively. In this way, the table 3 is configured.

  In the second embodiment, when the table 3 is transformed into a chair, the vacuum state of the shape memory members 56 and 57 is released. When the vacuum state of the shape memory members 56 and 57 is released, air enters the shape memory members 56 and 57, so that the shape memory members themselves become soft. Therefore, the movable support members 35 and 36 can be turned into a chair by rotating. In the second embodiment, as in the first embodiment, the positions of the backrest 31b and the footrest 31c can be reversed only by controlling the rotation direction of the movable support members 35 and 36. Therefore, the subject can be transformed not only into a chair suitable for transporting the subject from the leg portion to the magnet 2 but also into a chair suitable for transporting the subject from the head to the magnet 2.

  Further, by curing the shape memory members 56 and 57, each plate is fixed with respect to the adjacent plate. Therefore, even if the cradle is moved, the distance Δd (see FIG. 21) between the adjacent plates does not change. Can be.

(3) Third Embodiment The third embodiment is different from the first embodiment in the structure of the cradle, but the other configuration is the same as the first embodiment, and therefore the third embodiment is mainly related to the cradle. The structure of will be described.

  FIG. 35 is a perspective view of the cradle 60 according to the third embodiment, and FIG. 36 is a top view and a side view of the cradle 60.

  The cradle 60 has three plates 61, 62, and 63. The plate 61 and the plate 62 are connected by connecting members 64A and 64B. The connecting members 64A and 64B connect the plates 61 and 62 to each other so that the plate 62 can move with respect to the plate 61 in the direction of arrow P (see the side view of FIG. 36). The connecting members 64A and 64B are configured to be able to bend. By bending the connecting members 64A and 64B, the plate 62 can be moved in the P direction (see the side view of FIG. 36) with respect to the plate 61. . As the connection members 64A and 64B, for example, an articulated link can be used.

  The plate 61 and the plate 63 are connected by connecting members 65A and 65B. The connecting members 65A and 65B connect the plates 61 and 63 to each other so that the plate 63 can move in the arrow Q direction (see the side view of FIG. 36) with respect to the plate 61. The connecting members 65A and 65B are configured to be able to bend. By bending the connecting members 65A and 65B, the plate 63 can be moved with respect to the plate 61 in the Q direction (see the side view of FIG. 36). . As the connection members 65A and 65B, for example, an articulated link can be used.

Next, the internal structure of the cradle 60 will be described.
FIG. 37 is a view showing the internal structure of the cradle 60. FIG. 37A is a perspective view of the cradle 60, and FIG. 37B is a plan view of the cradle 60.
A pulley 66 and two pins 67A and 67B are embedded in the plate 61. The pin 67A is located between the connection member 64A and the connection member 65A, and the pin 67B is located between the connection member 64B and the connection member 65B.

  A bush 68A into which the end a1 of the pin 67A is inserted is embedded in the plate 63. The bush 68A is embedded at a position adjacent to the connection member 65A. Further, a bush 68B into which the end b2 of the pin 67B is inserted is embedded in the plate 62. The bush 68B is embedded at a position adjacent to the connection member 64B.

  The pulley 66 is configured to be able to rotate in the clockwise direction CW and the counterclockwise direction CCW around the point c. By rotating the pulley 66 counterclockwise CCW, the pin 67A can be inserted into the bush 68A of the plate 63 and the pin 67B can be inserted into the bush 68B of the plate 62. Hereinafter, the role of the pins 67A and 67B will be described with reference to FIGS. 38 and 39. FIG.

  38 is a plan view of the cradle 60 before the pulley 66 is rotated counterclockwise CCW, and FIG. 39 is a plan view of the cradle 60 after the pulley 66 is rotated counterclockwise CCW. 38 and 39 also show an AA sectional view and a BB sectional view.

  Before the pulley 66 is rotated, the pins 67A and 67B are housed in the plate 61 as shown in FIG. The connecting member 65A on the end a1 side of the pin 67A has a cavity KA (see the AA sectional view of FIG. 38) for penetrating the pin 67A, and this cavity KA is connected to the bush 68A.

  Further, the connecting member 64B on the end b2 side of the pin 67B has a cavity KB (see the BB sectional view of FIG. 38) for penetrating the pin 67B, and this cavity KB is connected to the bush 68B. Yes.

  When the pulley 66 is rotated in the counterclockwise direction CCW, the pin 67A is pushed out in the moving direction DA (see the AA sectional view of FIG. 38). Since the connecting member 65A has the cavity KA, when the pin 67A is pushed out in the moving direction DA, the end a1 of the pin 67A penetrates the connecting member 65A and is inserted into the bush 68A. The state in which the end a1 of the pin 67A is inserted into the bush 68A is shown in the AA sectional view of FIG. Since the pin 67A penetrates the connecting member 65A, the connecting member 65A cannot be deformed. Therefore, the two plates 61 and 63 can be fixed to each other so that the plate 63 does not move relative to the plate 61.

  Further, when the pulley 66 is rotated in the counterclockwise direction CCW, the pin 67B is pushed out in the moving direction DB (see the BB cross-sectional view in FIG. 38). Since the connection member 64B has the hollow KB, when the pin 67B is pushed out in the movement direction DB, the end b2 of the pin 67B penetrates the connection member 64B and is inserted into the bush 68B. A state in which the end b2 of the pin 67B is inserted into the bush 68B is shown in the BB cross-sectional view of FIG. Since the pin 67B penetrates the connecting member 64B, the connecting member 64B cannot be deformed. Accordingly, the two plates 61 and 62 can be fixed to each other so that the plate 62 does not move relative to the plate 61.

  Thus, the plates 62 and 63 can be fixed to the plate 61 by inserting the pins 67A and 67B into the bushes 68A and 68B, respectively.

In order to pull out the pins 67A and 67B from the bushes 68A and 68B, the pulley 66 may be rotated in the clockwise direction CW. When the pulley 66 is rotated in the clockwise direction CW, the pins 67A and 67B are pulled out from the bushes 68A and 48B and stored in the plate 61 (see FIG. 38). Therefore, the fixation of the plate can be released.
The cradle 60 is configured as described above.

  The cradle 60 is attached to the cradle support base 32. FIG. 40 is a view for explaining how the cradle 60 is attached to the cradle support base 32. The plates 61, 62, and 63 of the cradle 60 are positioned on the support members 34, 35, and 36 of the cradle support base 32, respectively. In this way, the table 3 is configured.

  In the third embodiment, when the table 3 is transformed into a chair, the pins 67A and 67B are stored in the plate 61. Therefore, the movable support members 35 and 36 can be turned into a chair by rotating. In the second embodiment, as in the first embodiment, the positions of the backrest 31b and the footrest 31c can be reversed only by controlling the rotation direction of the movable support members 35 and 36. Therefore, the subject can be transformed not only into a chair suitable for transporting the subject from the leg portion to the magnet 2 but also into a chair suitable for transporting the subject from the head to the magnet 2.

  Further, by inserting the pins 67A and 67B into the plates 62 and 63, each plate is fixed to the adjacent plate. Therefore, even if the cradle is moved, the distance Δd (see FIG. 21) between the adjacent plates is maintained. It can be prevented from changing.

(4) Fourth form The fourth form is different from the first form in the structure of the table, but the other configuration is the same as the first form, so the fourth form is mainly a table. The structure of will be described.

FIG. 41 is an explanatory diagram of the structure of the table 3 in the fourth embodiment.
41 (a) is a perspective view of the table 3, and FIG. 41 (b) is an exploded perspective view of the table 3.
The table 3 includes a cradle 90 that supports the subject 13 and a cradle support base 70 that supports the cradle 90.

FIG. 42 is a diagram showing the cradle support base 70.

The connection member 78 connects the movable support member 74 to the fixed support member 72 so that the movable support member 74 can move relative to the fixed support member 72.

Further, the movable support member 75 is connected to the movable support member 73 by a connection member 79, and the movable support member 76 is connected to the movable support member 74 by a connection member 80. The connection member 79 connects the movable support member 75 to the movable support member 73 so that the movable support member 75 can move relative to the movable support member 73. The connecting member 80 connects the movable support member 76 to the movable support member 74 so that the movable support member 76 can move relative to the movable support member 74.
As the connection members 77 to 80, for example, an articulated link can be used.

  Further, the cradle support base 70 includes cylinders 81 to 84. The cylinder 81 is for rotating the movable support member 73 relative to the fixed support member 72, and the cylinder 82 is for rotating the movable support member 74 relative to the fixed support member 72. The cylinder 83 is for rotating the movable support member 75 relative to the movable support member 73, and the cylinder 84 is for rotating the movable support member 76 relative to the movable support member 74. Since the four movable support members 73 to 76 can be rotated by the expansion and contraction of the cylinders 81 to 84, the cradle support base 70 can be deformed into various shapes.

Next, the structure of the cradle 90 will be described.
FIG. 43 is an explanatory diagram of the structure of the cradle 90. 43 (a) is a perspective view of the cradle 90, and FIG. 43 (b) is an exploded perspective view of the cradle 90. FIG.

  Connection member 911g: The connection member 911g connects the plates 911a and 911c to each other so that the plate 911c can move in the arrow Q direction with respect to the plate 911a. The connecting member 911g is configured to be bent. When the connecting member 911g is bent, the plate 911c can be moved in the Q direction with respect to the plate 911a.

  Connection member 911h: The connection member 911h connects the plates 911b and 911d to each other so that the plate 911d can move in the arrow R direction with respect to the plate 911b. The connecting member 911h is configured to bend, and the plate 911d can be moved in the R direction with respect to the plate 911b by bending the connecting member 911h.

  Connection member 911i: The connection member 911i connects the plates 911c and 911e to each other so that the plate 911e can move in the arrow S direction with respect to the plate 911c. The connecting member 911i is configured to bend, and the plate 911e can be moved in the S direction with respect to the plate 911c by bending the connecting member 911i.

As the connection members 911f to 911i, for example, an articulated link can be used.
The cradle 90 is configured by sticking the pad 912 to the surface of the cradle base 911 configured as described above. Since the structure of the pad 912 is the same as that of the pad 312 in the first embodiment, the description of the pad 912 is omitted.

  The cradle 90 is attached to the cradle support base 70. FIG. 44 shows a state where the cradle 90 is attached to the cradle support base 70. The plates 911a to 911e of the cradle 90 are positioned on the support members 72 to 76 of the cradle support base 70, respectively. In this way, the table 3 is configured.

The table 3 configured as described above can be transformed into a chair by rotating the movable support members 73 to 76 of the cradle support base 70. FIG. 45 shows an example when the table 3 is transformed into a chair. The table 3 of FIG. 45 represents the shape when the movable support member is rotated as follows.
(1) The movable support member 73 is rotated downward with respect to the fixed support member 72, and the movable support member 74 is rotated upward with respect to the fixed support member 72.
(2) The movable support member 75 is rotated so that the angle formed between the movable support member 73 and the movable support member 75 is 90 °.

In FIG. 45, the cradle 90 can be mainly divided into the following three parts.
(1) Seat surface 90a
(2) Backrest 90b
(3) Step 90c

  FIG. 46 shows a state when the subject 13 sits on the table 3 transformed into a chair. The step platform 90 c can be used as a scaffold when the subject 13 sits on the table 3.

  Note that the positions of the backrest 90b and the footrest 90c may be reversed. FIG. 47 shows the table 3 when the positions of the backrest 90b and the footrest 90c are reversed.

  Since the table 3 can be transformed into a chair in the fourth embodiment as well as the first embodiment, the load applied when the subject 13 gets on the table 3 and when the subject 13 gets off the table 3. The burden on the technician who assists the person 13 to get on and off the table 3 can also be reduced.

  Further, in the fourth embodiment, the table 3 is transformed into a chair having a step 90c. Therefore, when the subject 13 sits on the table 3 transformed into a chair, his / her feet can be placed on the footrest 90c, so that the subject 13 can be easily seated on the chair.

  In the fourth embodiment, a cradle 90 having a pad 912 is described as an example of a cradle having five plates. However, a cradle having a structure different from that of the cradle 90 may be used. 48 and 49 show examples of cradle having another structure.

  The cradle 110 of FIG. 48 includes five plates 111 to 115, connecting members 116 to 119 that connect adjacent plates, and shape memory members 121 to 124. The shape memory members 121 to 124 are disposed between adjacent plates. When the shape memory members 121 to 124 are cured, adjacent plates can be fixed to each other. Further, the shape memory members 121 to 124 are softened so that the plate can be moved.

  The cradle 130 of FIG. 49 includes five plates 131 to 135 and connecting members 136A and 136B to 139A and 139B that connect adjacent plates.

  A pulley 141 and two pins 142A and 142B are embedded in the plate 131. A bush 143A into which the pin 142A is inserted is embedded in the plate 133, and a bush 143B into which the pin 142B is inserted is embedded in the plate 132.

  By rotating the pulley 141 counterclockwise CCW, the pin 142A can be inserted into the bush 143A of the plate 133, and the pin 142B can be inserted into the bush 143B of the plate 132. Therefore, the plates 132 and 133 can be fixed with respect to the plate 131. Further, by rotating the pulley 141 in the clockwise direction CW, the pins 142A and 142B are pulled out from the bushes 143A and 143B, respectively. Therefore, the fixed state of the plates 132 and 133 can be released.

  In addition, a pulley 144 and one pin 145 are embedded in the plate 134, and a bush 146 into which the pin 145 is inserted is embedded in the plate 132. By rotating the pulley 144 counterclockwise CCW, the pin 145 can be inserted into the bush 146, so that the plate 134 can be fixed to the plate 132. Further, the pin 145 is pulled out from the bush 146 by rotating the pulley 144 in the clockwise direction CW. Therefore, the fixed state of the plate 134 can be released.

  Further, a pulley 147 and one pin 148 are embedded in the plate 135, and a bush 149 into which the pin 148 is inserted is embedded in the plate 133. By rotating the pulley 147 in the counterclockwise direction CCW, the pin 148 can be inserted into the bush 149, so that the plate 135 can be fixed to the plate 133. Further, the pin 148 is pulled out from the bush 149 by rotating the pulley 147 in the clockwise direction CW. Therefore, the fixed state of the plate 145 can be released.

(5) Fifth Mode The fifth mode is the same as the first mode except for the structure of the cradle pad, which is different from the first mode. Therefore, in the description of the fifth embodiment, the structure of the pad will be mainly described.

  FIG. 50 is a diagram showing the structure of the pad 312 in the fifth embodiment. FIG. 50A is an external perspective view of the pad 312, and FIG. 50B is a diagram showing the inside of the pad 312.

  The pad 312 has a bag body 312a and a granular body 312b accommodated in the bag body 312a.

  The bag body 312a has a partition 312c for dividing the inside of the bag body 312a into a plurality of spaces 312d. The partition 312c is provided in a mesh shape. A space 312d defined by the partition 312c is packed with granular materials 312b.

  The pad 312 configured as described above is attached to the surface of the cradle base 311, and the cradle 31 is configured. Hereinafter, advantages of the pad 312 in the fifth embodiment will be described with reference to FIGS. 51 and 52.

  FIG. 51 is a diagram showing a state in which the table 3 using the pad 312 in the fifth embodiment is transformed into a chair, and FIG. 52 is a diagram of the table 3 using the pad 312 without the partition 312c being transformed into a chair. It is a figure which shows a mode when letting it be made.

  When the table 3 is transformed into a chair, the backrest 31b and the footrest 31c of the cradle 31 are inclined obliquely. Therefore, the granular material 312b accommodated in the pad 312 moves downward due to gravity. At this time, in FIG. 52, since the partition 312c is not provided in the pad 312, the granular material 312b inside the pad 312 tends to be biased to the lower side of the backrest 31b or the lower side of the footrest 31c. Therefore, it is considered that the sitting comfort when the subject 13 sits on the chair is deteriorated. However, as shown in FIG. 51, by dividing the interior of the pad 312 into a plurality of spaces 312d by partitions 312c, the movable range of the granular material 312b accommodated in each space 312d is limited to each space 312d. be able to. Therefore, the unevenness of the granular material 312b in the pad 312 can be reduced, and the sitting comfort of the subject 13 can be improved.

  In the fifth embodiment, the partition 312c is provided so that the space 312d has a rectangular parallelepiped shape, but the shape of the space 312d is not limited to the rectangular parallelepiped. For example, the partition 312c may be provided so that the space 312d has a disk shape, an elliptical shape, a triangular shape, or a rhombus shape.

  In the first to fifth embodiments, the MR apparatus is described. However, the present invention can be applied to a medical apparatus (for example, a CT apparatus) other than the MR apparatus as long as the medical apparatus includes a cradle that supports the subject.
