Description

  Embodiments of the present invention relate to a medical system.

In recent years, cases of dealing with one disease using image diagnosis and treatment by a plurality of medical devices are increasing. An example of such closely related medical devices is X-ray CT (Co
mputed Tomography and MRI (Magnetic Resonance)
e Imaging) images may be superimposed to obtain a fusion image, or a radiotherapy apparatus that determines the position of radiation irradiation based on the image. Some radiotherapy apparatuses use X-rays generated by colliding electrons with an X-ray target, and others use γ-rays emitted from radioisotopes.

Positioning is very important in these radiation treatments. In the case of radiotherapy using a radiotherapy device, it is necessary to capture in advance an image for positioning to irradiate radiation,
Radiation is applied to the affected area based on the image. For this reason, the subject is not allowed to move from the bed until the radiation is irradiated after the image is acquired.

That is, one subject uses the CT apparatus and the radiation therapy apparatus in succession.

In this case, the CT apparatus and the radiotherapy apparatus exist in the same room, and are often used for diagnosis and treatment of only one subject. This is because there is a risk of exposure, and thus it is impossible to perform diagnosis and treatment with a CT apparatus and a radiotherapy apparatus on two subjects at the same time in the same room. Thus, for example, there is an inefficiency that the device cannot be used for another subject until the diagnosis and treatment of the previous subject is completed, even though there is a device that is not being used.

In radiotherapy, conventionally, the diagnostic imaging apparatus and the radiotherapy apparatus sometimes use separate beds. However, since the bed of the image diagnostic apparatus such as a CT apparatus and the radiation therapy apparatus is not of a common structure and strength, the magnitude of the deflection of the top plate caused by the weight of the subject is different. Since the difference in deflection between the beds affects the positioning, the deflection error must be taken into consideration when positioning.

On the other hand, it is difficult to install the MRI apparatus and the radiotherapy apparatus in the same room because the magnetic material used in the radiotherapy apparatus may affect the magnetic field of the MRI apparatus.

  Hereinafter, embodiments for carrying out the invention will be described.

(First embodiment)
An outline of the medical system of the first embodiment will be described with reference to FIG.

FIG. 1 is a schematic diagram illustrating an example of the overall configuration of the first embodiment. MRI room 12 has MRI
The apparatus 10 and the radiotherapy room 22 are provided with a radiotherapy apparatus 20, and a rail portion 60 is installed on the floor. The MRI room 12 and the radiation therapy room 22 are provided with doors 90. In the present embodiment, image diagnostic apparatuses such as CT apparatuses and MRI apparatuses, and radiotherapy apparatuses are collectively referred to as medical apparatuses. The couch 70 is provided for the number of medical devices or more, and is moved between the medical devices along the rail portion 60 and used in common.

The MRI apparatus 10 generates a strong magnetic field, and nuclear magnetic resonance (Nuclear Magnetic).
A tomographic image of the subject can be taken using the principle of resonance (NMR), and anatomical information and biochemical information can be obtained. A self-propelled gantry 11 is provided. Since positioning is important during radiotherapy, the gantry 11 is moved while the bed 70 and the top plate are fixed in order to prevent an error due to deflection of the top plate (not shown). This is because it is necessary to make a diagnosis. When the bed 70 is fixed to the gantry 11 at a predetermined position, the bed 70 can move in a direction approaching the bed 70 or a direction away from the bed 70.

In the radiation therapy apparatus 20, a position where a radiation source provided in the gantry 21 rotates around an axis in the body axis direction of a subject and the radiation irradiated from the radiation source gathers is called an isocenter. Then, irradiation is positioned based on the image obtained by the MRI apparatus 10, and the affected part of the subject is irradiated with radiation.

The door 90 is provided in a room of each medical device, shields radiation and magnetic field, and a bed 70 is provided to allow access to the room provided with each medical device.

The couch 70 is for carrying a subject and carrying it to each medical device, and is commonly used for the MRI apparatus 10 and the radiation therapy apparatus 20.

The rail part 60 is for moving the bed 70 to each medical device. And MRI apparatus 10
It is installed at a predetermined position facing the gantry 11 and a predetermined position near the gantry 21 of the radiation therapy apparatus 20 and is provided on the floor without interruption. The rail portion 60 may be installed by being buried in the floor, or may be installed in a state of protruding on the floor. When buried in the floor, at least the upper surface of the rail part is exposed to the outside. The rail unit 60 provided in the room where the MRI apparatus 10 is installed is assumed to be non-magnetic.

Here, the rail portion 60 needs to have a layout such that the beds do not come into contact with each other when the plurality of beds are moved simultaneously between the medical devices. For example, the layout has a plurality of paths as shown in FIG. In FIG. 1, a plurality of routes means an MRI room 12 and a radiation treatment room 22.
This means a path (path 1) that moves linearly and a path (path 2) that moves around the outside when the couch 70 is moved between the two. At this time, the interval between the parallel rail portions 60 is at least equal to the width of the bed for at least one bed so that the two beds 70 and 70a can pass each other. FIG. 2 shows a state in which the bed 70 moves along the path 1 and the bed 70a moves along the path 2.

Not limited to the above, it can be said that the bed has a plurality of paths when moving between the MRI apparatus 10 and the radiation therapy apparatus 20 even when the layout shown in FIG. The route 1 is a straight route, and the route 2 is a route that once retreats to the side and then returns to the route 1 again.
In this embodiment, in this way, when the plurality of beds move on the rail portion, the bed moves to a position once deviated from the shortest route toward the destination medical device, and then returns to the original route again. The distance of the couch when moving is counted as one route.

Here, in FIG. 1, the path from the MRI room 12 to the radiation therapy room 22 is indicated by an arrow and is indicated as a path 1 and a path 2, but conversely, when moving from the radiation therapy room 22 to the MRI room 12, If it moves along the arrow in the opposite direction, it is a similar path. That is, when moving linearly from the radiation therapy room 22 to the MRI room 12, it is the path 1.
If it moves around the outside, it is route 2.

Further, “branch” means that there are two or more roads where a rail portion branches at a certain place. In FIG. 1, a branch is made once in the middle of the route 2. As shown in FIG. 5, even a layout in which at least two routes can be obtained by providing the movable rail portion 62 and connecting to the rail portion 60 is also called a branch.

The rail portion 60 may take an annular layout. What is an annular layout?
This refers to a layout having a curve as shown in a). In the present embodiment, for example, FIG.
A layout having at least one corner as shown in FIG. 6 and a plurality of corners as shown in FIG. That is, in FIG. 1, it can be said that the rail portion 60 has an annular and branched layout.

As for the layout of the rail portion 60, for example, there are cases where one end of the rail portion is not connected anywhere as shown in FIG. 1, and there is a case where only one annular layout is provided and no end exists as shown in FIG. is there. When there is an end, at least one end comes at a position off the straight line connecting the MRI apparatus 10 and the radiotherapy apparatus 20. The position deviated from the straight line refers to a position where one end of the rail portion 60 is located next to the branch point shown in FIG. In the present embodiment, such a position is referred to as a position not related to the medical device.

Here, FIG. 3 is a schematic view showing an example in which the MRI apparatus 10, the radiation therapy apparatus 20, and the CT apparatus 30 are provided in the MRI room 12, the radiation therapy room 22, and the CT room 31, respectively. Taking such a layout as an example, there are five ends of the rail portion 60 at positions not related to the medical device. In order to put in and out the bed 70, it is preferable that one end of the rail portion 60 exists at a position close to a room provided with each medical device, as shown in FIG. In addition to the door 90, a door 91 for an operator to enter and exit may be provided.

Since the radiotherapy apparatus 20 provided in the radiotherapy room 22 shown in FIG. 7A uses radiation for treatment, the radiotherapy room 22 is directed in the left-right direction (X direction) toward the front of the gantry 21 for radiation protection. ) Wall 90 needs to be thickened. This is the radiation source 2 as shown in FIG.
3 and the detector 24 rotate around the Y direction. Therefore, in order to make the door installed in the Y direction as a path of the bed 70 light and simple, it is desirable that the medical devices are installed to face each other.

On the other hand, since the MRI apparatus 10 performs imaging using NMR, a high magnetic field is generated. A magnetic shield plate is provided on the wall of the MRI chamber 12 in which the MRI apparatus 10 is installed so that an internal strong magnetic field and radio waves are not leaked and are not affected by these.

FIG. 8 is a perspective view of the bed 70. The bed 70 has wheels 71 on the bottom surface, and is provided with a connecting portion 73 at a predetermined location. Although this connection part 73 is accommodated in the bed 70 in the drawing, it may be arranged to be exposed on the side surface. A projection 72 is provided on the bottom surface of the bed 70. The protrusion 72 is not necessarily located in the middle of the bottom surface of the bed 70, and may be provided at any location on a straight line that bisects the width of the bed 70. If it is on this straight line, it may be provided on the side surface of the bed 70 instead of the bottom surface of the bed 70. Further, since the bed 70 is used in the MRI apparatus, the bed 70 is entirely made of a nonmagnetic material like the rail portion 60.

FIGS. 9A and 9B are side views showing the relationship between the bed 70 and the floor 50. The floor 50 is provided with a recess 51 into which the connection portion 73 provided in the bed 70 can be inserted. Shows an example in which the floor 50 and the bed 70 are fixed. Bed 7 without shifting from the isocenter position
In order to install 0 in each medical device, the floor 50 is previously provided with a mechanism for assisting the coupling with the bed 70. For example, as shown in FIG. 9 (a), the connecting portion 73 may be inserted into the recess 51 provided on the floor 50 from the bed 70 side and fixed as shown in FIG. 9 (b), or conversely The connecting portion provided on the 50 side may be inserted into the bed 70. In addition, various means that can fix the bed 70 in a fixed position are applicable. When the connecting portion 73 is provided inside the bed 70, a grip portion (not shown) for operating the connecting portion 73 may be exposed outside the bed 70. In addition, in order to prevent the bed 70 from moving from a predetermined position during use of the apparatus, a mechanism is provided so that the connecting portion 73 does not come off the recess 51 when the above-described recess 51 is used as an example. deep. For example, when a mechanism for fixing the connection portion 73 to the floor 50 or the recess 51 and a sensor for detecting opening / closing of a door of the room are installed and the door is closed, the connection portion 73 is fixed to the recess 51. There are means such as making it impossible to move. In addition, for example, a communication unit provided in the bed 70 may acquire the usage information of the apparatus, and the connection unit 73 or the wheel 71 may be fixed based on the information.

FIGS. 10A and 10B are schematic diagrams showing the relationship between the bed 70 and the rail portion 60. The rail portion 60 is provided with a groove 61, and the groove 61 has a space that allows a projection 72 provided at the lower portion of the bed 70 to enter. The bed 70 is arranged such that the wheels 71 straddle the rail portion 60, and the protrusion 72 enters the groove 61 of the rail portion 60. The wheel 71 of the bed 70 is moved during the movement.
May get over the rail portion 60, so that the wheel 71 does not get caught in the groove 61.
The width of the groove 61 is preferably narrower than the width of the wheel 71. The tip of the projection 72 may be provided with a wheel 71, or the portion of the rail 60 that enters the groove 61 may be configured to be rotatable in the major axis direction of the projection 72.

FIG. 12 shows the rail portion 60 and the protruding portion 7 when the tip of the protruding portion 72 is rotatable in the major axis direction.
It is the figure which showed the relationship of 2. When the bed 70 is moved, there may be a case where the protrusion 72 collides with a side surface on one side of the groove 61 of the rail portion 60. Therefore, in order to smoothly move the bed 70, a mechanism capable of rotating the front end of the protrusion 72 in the major axis direction may be provided.

When the wheel 71 is provided at the tip (not shown), the height is the same as that of the wheel 71 provided on the bottom surface of the bed 70. When the tip portion is made rotatable, the rotating portion is required to have a cylindrical shape. Further, when the rail portion 60 is installed in a state of being embedded in the floor 50 as shown in FIG. 10B, in order to accommodate the protruding portion 72 in the groove 61 of the rail portion 60, it protrudes below the floor surface. The part 72 needs to be arranged. In that case, the bed 70 is provided with a mechanism for moving the protrusion 72 up and down.

Here, the door 90 provided in the room provided with each medical device includes a mechanism that does not open during diagnosis and treatment, for example, electronic control is performed so that the lock is always applied during radiation irradiation.
The door 90 may be a hinged door or a sliding door, and various structures are applicable.

Next, the operation of the medical system according to the present embodiment will be described.

Positioning is necessary for performing radiotherapy, and the subject 8 is used to obtain an image used for the positioning.
An example of using the MRI apparatus 10 for 0A will be described with reference to the flowchart of FIG.

In step S101, the operator places the subject 80A on the bed 70.

In step S102, the operator determines whether the MRI apparatus 10 is available.
If not available (Y), the process proceeds to step S103. If not available (N), the process waits until it is available.

In step S103, the operator moves the bed 70 along the rail portion 60 to the MRI apparatus 10 using the wheels 71 provided at both ends of the bottom surface of the bed 70, and fixes the bed 70 to the floor 50 by the method described above.

In step S104, the operator moves the gantry 11 in the body axis direction of the subject 80A and images the subject 80A with the MRI apparatus 10. Here, if there is a plan to use the MRI apparatus 10 for another subject, the subject is placed on another bed in advance to prepare for imaging.

In step S105, after the imaging of the subject 80A by the MRI apparatus 10, the operator determines whether or not to use the radiation therapy apparatus 20 for the subject 80A. When used (Y), the subject 80 is placed on the bed, and the process proceeds to step S106. When not used (N)
) Ends.

In step S <b> 106, the operator moves the bed 70 used for the MRI apparatus 10 to the outside of the MRI room 12. Taking FIG. 1 as an example, it is moved along path 1. The reason for moving outside the room is to enable the MRI apparatus 10 to be used for the next subject.

In step S107, the operator determines whether or not the radiation therapy apparatus 20 is available. If it is not available (Y), the process proceeds to step S108. If it is not available (N), it waits until it is available.

In step S <b> 108, the operator moves along the path 1 following step S <b> 6 and moves the bed 70 to the radiation therapy apparatus 20. Then, the bed 70 is fixed to the floor 50 as in step S3. At this time, if the radiotherapy apparatus 20 has been used for another subject until immediately before, the other operator moves the bed on which the subject is placed through the route 2, and passes the route 1. Avoid contact with the sleeping bed 70.

In step S <b> 109, the radiologist performs radiation irradiation treatment on the subject 80 </ b> A using the radiation therapy apparatus 20. When the treatment is completed, the subject 80A is lowered from the bed 70, and the process ends.

Here, as shown in FIG. 11 (a), when making a left turn or a right turn when the bed 70 is moved, it may be moved while the direction of the protrusion 72 is fixed, or as shown in FIG. 11 (b). Projection 72
You may move while changing the angle. When the bed 70 is moved to another medical device installed at the opposite position, the bed 70 needs to be rotated 180 degrees during the movement. Although the bed 70 can be rotated anywhere on the rail portion 60, FIGS. 11 (a) and 11 (b).
Since the space of the groove 61 is wide at the branch point of the rail portion 60 shown in FIG.
Suitable for performing the rotation. It goes without saying that there is no problem even if the bed 70 is moved in the reverse direction after making a left turn (right turn) once at the branch point without rotating on the spot.

By the way, when the bed 70 is in a range where the rail portion 60 does not exist and enters the rail portion 60 from there, it is confirmed that the protrusion 72 on the bottom surface of the bed 70 is in the groove 61 of the rail portion 60. To do. If the protrusion 72 is not in the groove 61, it cannot be used even if the bed 70 is moved to the medical device. Therefore, in such a state, it must be moved again to the position of the tip of the rail portion 60.

Next, effects of the medical system according to the present embodiment will be described.

As described above, according to the present embodiment, since the same bed can be used by a plurality of apparatuses, it can be directly carried to the radiotherapy apparatus 20 after using the MRI apparatus 10 for a subject. Therefore, in radiotherapy, it is possible to perform positioning without considering the deflection error of the bed 70. Therefore, positioning in radiotherapy is facilitated by MRI images, and advanced treatment that cannot be achieved by positioning such as VGRT using CT images can be easily performed. Then, as shown in FIG. 3, when the MRI room 12, the radiation treatment room 22, and the CT room 31 are provided, the MRI image and the CT image are fused to obtain a further optimum image for positioning in the radiation treatment. Can be obtained. Since confirmation of nerves and the like is facilitated by using the MRI image, it is possible to avoid nerve damage due to unnecessary radiation irradiation near the radiation irradiation site.

Further, by providing a plurality of paths when the couch 70 moves between apparatuses, it is possible to move a plurality of couches simultaneously. Therefore, for example, in FIG.
When moving to the radiotherapy apparatus 20 after performing tomographic imaging with the I apparatus 10, the MRI apparatus 10 is applied to the subject 80B that has been prepared for imaging in advance while performing image processing and the like for positioning. Can be used immediately. Moreover, in the case of the layout of the rail part 60 as shown in FIG. 2, since two beds can pass each other, a plurality of beds can be moved more smoothly. On the other hand, in the case of the layout as shown in FIG.
Compared to the case of FIG. 2, the rail portion 60 that must be installed on the floor 50 can be minimized.

For the above reasons, according to the present embodiment, not only radiation therapy using an MRI image can be easily performed, but also the burden on the patient can be reduced and diagnosis and treatment can be performed efficiently.

In addition, when the tip of the protrusion 72 can be rotated in the major axis direction of the protrusion 72 as shown in FIG. 12, the protrusion 72 not only prevents the bed 70 from overturning but also rotates so that the groove 61 of the rail portion 60 is provided. The bed 70 can be moved smoothly by avoiding energy loss due to friction between the side surface of the projection and the protrusion 72. On the other hand, when a wheel is provided at the tip of the protrusion 72, the bed 70
The bed can be supported not only by the wheel 71 provided on the bottom surface of the door but also by the wheel at the tip of the protrusion 72, and as a result, the bed 70 can be easily moved. And the rail part 60 is placed on the floor 5
When embedded in 0 (FIG. 10B), there is no step at the boundary between the rail portion 60 and the floor 50, so that there is an advantage that the bed 70 can be easily moved.

(Second Embodiment)
Next, a second embodiment will be described with reference to FIG.

FIG. 13 is a schematic diagram illustrating an example of the overall configuration of the second embodiment. This is a form in which the number of medical devices and couches is increased as compared to the first embodiment, and the mechanism of the rail portion and the couch is not different from that of the first embodiment, and thus description thereof is omitted here.

FIG. 13 shows an MRI with one radiotherapy apparatus 20 in each of two radiotherapy rooms 22.
MRI apparatus 10 in chamber 12, CT apparatus 30 in CT room 31, and PET (P
An example in which an ostron emission tomography) apparatus 40 is installed and eight couches 70 are provided is shown. In this case, the waiting couch 70 is the CT shown in FIG.
It is desirable to arrange in a space between the apparatus 30 and the MRI apparatus 10. This is because it is easy to move because it is close to each medical device. In the case where the subject is placed on the bed 70 and waiting before using the apparatus, it is preferable to move the object from the above space to the vicinity of the apparatus.

Here, the operation of the medical system of this embodiment will be described based on the flowchart of FIG.

In step S <b> 201, the operator places the subject on the bed 70.

In step S202, the operator determines whether the diagnostic imaging apparatus is available. If it is not available (Y), the process proceeds to step S203. If it is not available (N), it waits until it is available.

In step S203, the operator moves the bed to the diagnostic imaging apparatus and fixes the bed 70 to the floor.

In step S204, the operator moves the gantry of the image diagnostic apparatus and images the subject. After the imaging is completed, the processing of the image obtained in step S204 and the correction of the treatment plan are performed in parallel with the operations after step S205. Since it takes time to fuse images taken by a plurality of diagnostic imaging apparatuses, change the irradiation field, and recalculate the irradiation dose, they are performed when the bed is moved.

In step S205, the operator determines whether to use another diagnostic imaging apparatus after imaging in step S204. If used, go to step S205a, otherwise go to step S206.

In step S205a, the operator moves the bed 70 and moves away from the diagnostic imaging apparatus used in step S204, and then proceeds to step S202. Here, from the diagnostic imaging apparatus to the bed 70
The reason for immediately moving is that it is possible to use the diagnostic imaging apparatus used in step S204 for another subject.

In step S206, the operator determines whether or not to use the radiation therapy apparatus 20. When used (Y), the process proceeds to step S207, and when not used (N), the diagnosis and treatment for the subject are terminated.

In step S207, the operator moves the bed 70 to the radiation therapy apparatus 20.

In step S208, the operator determines whether or not the radiation therapy apparatus 20 is available. If it is available (Y), go to step S209. If it is not available (N), it waits until it is available.

In step S <b> 209, the operator moves the bed 70 to the radiation therapy apparatus 20 and fixes the bed 70 to the floor 50.

In step S210, the radiologist uses the radiation treatment apparatus 20 to irradiate the subject with radiation and performs treatment. When the treatment is finished, the diagnosis and treatment for the subject are finished.

As an effect which this embodiment has, the bed which can be used in common is used as the MRI apparatus 10 and the CT apparatus 30.
By using both of these devices, it becomes possible to easily use a fusion image of an MRI image and a CT image for positioning of radiotherapy, and more advanced treatment can be performed.

Then, the images taken by a plurality of diagnostic imaging apparatuses are fused, and IGRT (Image-g
uided radiotherapy: image-guided radiation therapy) and ART (Adapti)
When performing radiotherapy (adaptive radiotherapy) or the like, it is possible to change the irradiation field and recalculate the irradiation dose, which takes time for processing, while moving the bed 70.
That is, the efficiency in radiotherapy is improved by performing the calculation process in parallel with the movement of the bed 70 and the setting to the radiotherapy apparatus 20.

Also, it is naturally possible to efficiently use each device in this embodiment. For example, in FIG. 13, when the subject 80C and the subject 80D use the MRI apparatus 10 and the radiation therapy apparatus 20, respectively, and there is another subject that needs to use only the CT apparatus 30,
It is also possible to use the CT apparatus 30 having a shorter apparatus use time for a large number of subjects as compared with the MRI apparatus 10 and the radiotherapy apparatus 20.

As described above, the use time of the CT apparatus 30 per time is the MRI apparatus 10 or the radiotherapy apparatus 20.
Therefore, it can be imagined that the bed 70 is frequently replaced in the CT room 31 for use. Therefore, as shown in FIG. 13, the tip of the rail portion 60, that is, the projection 70 on the bottom surface of the bed 70 is moved to a position close to the position where the projection 72 enters the groove 61 of the rail portion 60.
A device 30 is preferably provided. And the waiting bed 70 may be made to stand by on the rail part 60 near the room with each medical device to be used instead of the front-end | tip of the rail part 60 or the exterior like FIG. As a result, each medical device can be used more efficiently.

FIG. 13 shows an example in which the CT apparatus 30 and the MRI apparatus 10 are respectively installed facing the radiation therapy apparatus 20. This facilitates the movement of the bed 70 from the CT apparatus 30 to the radiation therapy apparatus 20 and the movement of the bed 70 from the MRI apparatus 10 to the radiation therapy apparatus 20 that are required during radiotherapy.

Here, in Embodiments 1 and 2, each medical device may be installed on a different floor, and the bed 70 may be moved using an elevator. In this case, it is possible to implement this embodiment even in hospitals and clinics where there is no space for installing each device on the same floor. In this embodiment, the radiotherapy is specifically described. For example, the CT apparatus 30 and the MRI apparatus 10
In addition, when there are a plurality of image diagnostic apparatuses such as the PET apparatus 40, the apparatus is also suitable for use on a common bed only among a plurality of image diagnostic apparatuses. That is, this embodiment is useful even in a medical institution that does not own the radiation therapy apparatus 20.
