Abstract

PROBLEM TO BE SOLVED: To control the operation of a bed and a top plate and set an imaging range with intuitive operation at the side of a subject.SOLUTION: A medical apparatus according to one embodiment includes: a bed supporting a top place for placing a subject; a bed operation part included in the bed, showing the range for diagnosis or medical treatment in the body axial direction of the subject and provided in the vicinity of the top plate; a detecting part for detecting the operation of the bed operation part by an operator; and a control part for controlling at least one of the bed and the top plate on the basis of the detection of the detecting part.

Description

  Embodiments described herein relate generally to a medical device.

  After placing the subject on the top board, the operator moves the bed and the top board to perform positioning in order to obtain a tomographic image of a desired site. At this time, the operator operates buttons provided on the gantry for the movement. Therefore, the line of sight of the operator when performing these movements is directed to a button provided on the gantry provided in a different direction from the subject placed on the top board at a substantially right angle. In addition, since the operator operates the buttons provided on the gantry, the operator has to leave the subject somewhat. Thereby, for example, when the subject is an infant or an elderly person, extra psychological anxiety due to the absence of the operator is given. In addition, the operation of the buttons provided on the gantry performed by the operator changes not only the bed and the top board but also the movement speed thereof. At this time, the operator must send his gaze to the many buttons provided on the gantry, and also to his gaze to the bed and the top board. This is not an easy task for the unskilled person, and there is a possibility that an appropriate and efficient diagnosis cannot be performed.

  Here, from the viewpoint of performing movement control of the bed and the top plate while being on the subject side, installing a button or the like for performing movement control of the bed and the top plate may be one solution. However, this is also not an easy operation for unskilled persons.

  In addition, the operator must leave the subject side in order to determine the imaging range by operating the console after positioning the subject.

FIG. 2 is a perspective view of the gantry 11 and the medical device according to this embodiment.

  The couch 30 includes a couch operation unit 31, an operation detection unit 32, a couch control unit 19, and a couchtop position detection unit 33, and supports the couchtop 15. The bed 30 is disposed so as to face the opening of the rotating ring 12. The bed 30 is provided with a mechanism that can move at least in the Y direction.

  The top plate 15 is provided on the bed 30 and has a mechanism that can move at least in the Z direction. The top plate 15 places the subject and moves it in the Z direction to guide the subject P to the opening of the rotating ring 12.

  The couch operating unit 31 is configured so that the operator P can easily perform an operation intuitively. The bed operation unit 31 preferably has a length corresponding to the length of the top plate 15 in the longitudinal direction, for example.

  The operation detection unit 32 detects the operation of the bed operation unit 31 by the operator P. The detection of the operation here refers to detecting the position of the bed operation unit 31 touched by the operator P, and detecting various operations such as a tap operation and a slide operation. The operation detection unit 32 detects the operation of the bed operation unit 31 by the operator P and sends the information to the bed control unit 19.

  The couch controller 19 controls the movement of the couch 30 and the top board 15 based on the information detected by the operation detector 32. The movement control at this time may be performed by the system control unit 22. That is, hereinafter, the movement control of the bed 30 and the couchtop 15 is described as being performed by the bed control unit 19, but the system control unit 22 may perform part or all of the functions. In that case, the system control unit 22 performs control based on various conditions set by the operator in the computer system 20.

Then, based on the current position information of the top 15 detected by the top position detector 33, the imageable range displayed on the bed operation unit 31 is determined. That is, when the position of the top plate 15 is shifted from the bed operation unit 31 that is provided on the bed 30 and indicates the imageable range, the imageable range is taken into consideration. The shootable range will be described in detail with reference to FIG.

  Hereinafter, the movement control of the bed 30 and the top 15 by the operation of the bed operation unit 31 will be described with reference to FIGS.

(Movement control of bed / top)
FIG. 3 is a schematic diagram showing an example of the couch operating unit 31 and its operation in the present embodiment.

  The couch operating unit 31 is provided on the side of the couch 30 or on the side of the couch 30 upper top plate 15 and is operated by a finger or the like of the operator P. In the present embodiment, an example in which a bed operation unit 31 is provided beside the upper top plate 15 of the bed 30 is shown.

  For example, the bed operation unit 31 includes a touch panel that displays a photographic range and the like and can perform various operations by a touch operation.

  The couch operating unit 31 illustrated in FIG. 3 indicates the imageable range. For example, as shown in FIG. 3, the range that can be photographed may be indicated by enclosing it with a square and distinguishing it by color, or by performing a line or marking. At this time, the position of the top plate 15 is detected by the top plate position detection unit 33, and the photographing possible range is determined based on the position of the top plate 15 at this time.

  The operator sets the α point and the β point by, for example, a touch operation within the illustrated shootable range. At this time, the operator may set “range A” by touching each of the α point and the β point, or may set “range A” by sliding operation from the α point to the β point. Good. As a result, as shown in FIG. 3, the “range A” set by the bed operation unit 31 is determined as a range in which a tomographic image of the subject P placed on the top 15 is captured. As a result, the bed controller 19 and the X-ray controller 28 automatically control the movement of the top 15 and the X-ray exposure from the X-ray tube 13 in consideration of the “range A”.

  After the “range A” is determined, the couch controller 19 moves the couch 15 by pressing a button such as “moving the couch” (see FIG. 4) provided on the couch 30 or the couch controller 31 or the like. Move to the X-ray path along the Z axis. At this time, the operator performs movement control in the Y-axis direction by a touch operation of the bed operation unit 31 in order to align the subject P placed on the top 15 with a preferable position on the Y-axis. This will be described below with reference to FIG.

  FIG. 4 is a schematic diagram illustrating an operation example of the bed operation unit 31 in the present embodiment.

  As shown in FIG. 4A, the couch operating unit 31 can be operated with an operator's finger or the like, and may perform button display as shown in FIG. 4B. These displays may be switched by a touch operation including a tap operation and a flick operation by an operator, or may be displayed at the same time. In that case, the couch operating unit 31 performs button display in an area other than the “shootable range” illustrated in FIG. 3.

  “Moving speed” in FIG. 4B indicates the moving speed of the bed 30 and the top board 15. The operator can select the moving speed of the bed 30 and the top board 15 by touching these buttons displayed on the bed operation unit 31.

  “Shooting mode 1” and “Shooting mode 2” in FIG. 4B are buttons for simply performing shooting according to, for example, preset conditions. The conditions here are, for example, the X-ray dose irradiated to the subject P, the moving speed of the bed 30 and the top 15, and the like. The imaging conditions may be easily set by using these buttons, or detailed settings such as the X-ray exposure time may be performed by the bed operation unit 31.

  Next, the operation of the bed operation unit 31 shown in FIG. 4A will be described with reference to FIG.

  FIG. 5 is a perspective view of the gantry 11 and the medical device according to the present embodiment, and a schematic diagram illustrating an operation example of the bed operation unit 31.

  The bed 30 is controlled to move in the direction of arrow 1 in FIG. 5 depending on the operation 1 of the bed operation unit 31 by the operator.

  The top plate 15 is controlled to move in the direction of the arrow 2 in FIG. 5 depending on the operation 2 of the bed operation unit 31 by the operator.

  In addition, for example, flick operation etc. are applied to operation 1 / operation 2 of the bed operation part 31 by the operator said here. At this time, after the operation detection unit 32 detects the operation 1 / operation 2 by the operator, the bed control unit 19 performs movement control of the bed 30 / top 15. The movement control of the bed 30 / top 15 by the bed control unit 19 may be performed after the operation 1 / operation 2 by the operator is completed, or may be performed during the operation 1 / operation 2. Various other means are applied to the movement control of the bed 30 / top 15.

  In addition to the movement control, various miscellaneous modifications that can perform desired control for the operator by various touch operations are applied.

  Moreover, it is preferable that the bed operation part 31 has a function for stopping the moving bed 30 and the top plate 15. For example, the “stop button” may be displayed and the operator may stop the operation by performing a touch operation, or may be performed by a tap operation or a flick operation of the bed operation unit 31 by the operator.

  FIG. 6 is a flowchart in the present embodiment.

(Step S1)
The operator places the subject P on the top board 15. The top plate position detection unit 33 detects the position of the top plate 15. The detection of the top plate position is performed depending on the operation of the bed operation unit 31 by the operator. The top plate position detection unit 33 may detect the top plate position by operating an “top plate position detection” button (not shown) displayed on the bed operation unit 31 by the operator, or simply perform the bed operation. It may be automatically performed depending on the operation of the unit 31.

(Step S2)
Based on the top board position detected in step S1, the couch operating unit 31 displays a shootable range.

(Step S3)
The operator checks the imageable range displayed on the bed operation unit 31. Then, by operating the bed operation unit 31, the “range A” to be photographed is touch-operated. (See Figure 3)
Further, the operator operates the couch operating unit 31 in order to perform the couch movement control in the Y-axis direction and the couchtop movement control in the Z-axis direction. (See FIG. 5) At this time, the operator performs alignment of the subject P using the laser emitted from the gantry 11. Therefore, the operator moves the couchtop 15 in the Z-axis direction by operating the couch operating unit 31 (for example, operation 2 in FIG. 5), and sends the subject P to the gantry 11. Then, while confirming the laser irradiated to the subject P, the operator performs alignment in the Y-axis direction by, for example, operation 1 in FIG.

(Step S4)
The operation detection unit 32 detects the touch operation performed in step S <b> 3 and transmits the information of “range A” to the bed control unit 19. The operator sets “range A” in step S3, and after the alignment in the Y-axis direction is completed, presses the “top move” button.

(Step S5)
Based on the “range A” detected in step S 4, the couch controller 19 controls the movement of the top 15. Note that the operator can stop the movement of the couchtop 15 by operating the couch operating portion 31 while the couch 30 and the couchtop 15 are moving. For example, as described above, the “stop button” may be displayed and stopped by the operator performing a touch operation, or may be performed by a tap operation or a flick operation of the bed operation unit 31 by the operator. .

(Step S6)
The bed control unit 19 controls the movement of the bed 30 and the top 15, and the subject P is inserted into the opening. Then, the X-ray control unit 28 performs X-ray exposure control in order to generate a diagnostic image of the subject P within the “range A” set in step S3.

(Step S7)
In the computer system 20, an image in the “range A” irradiated with X-rays in step S <b> 6 is generated. Then, the image display unit 27 displays the image.

  The X-ray CT apparatus has been described above as an example of the medical apparatus, but the present embodiment is not limited to this. The medical apparatus provided with the bed operation unit 31 in this embodiment can be applied as a bed in, for example, an MRI apparatus or a radiotherapy apparatus.

  Further, the movement control in the Z-axis direction need not be only the top plate 15. Depending on various situations, movement control of not only the top 15 but also the bed 30 may be performed.

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

  According to the present embodiment, when the bed is equipped with a bed operation unit, when an operator such as an engineer takes an image of the subject, the setting and alignment of the imaging range is performed immediately next to the bed on which the subject is placed. Etc. can be performed. Thereby, the operator can perform various operations while confirming the state of the subject. Therefore, the movement control of the bed and the top becomes easy for the operator, and the subject can feel a sense of security because the operator is nearby.

(Second Embodiment)
The medical device according to the present embodiment is different from the first embodiment in that the bed 30 has a speed detection unit 34. Further, in the medical device according to this embodiment, the bed control unit 19 controls the moving speeds of the bed 30 and the table 15 based on the table position detected by the table position detection unit 33, as compared with the first embodiment. Is different.

  FIG. 7 is a block diagram of the bed 30 in the present embodiment.

  The speed detection unit 34 detects the sliding speed of the bed operation unit 31 by the operator. The slide speed here is a speed in the slide operation from the α point to the β point when, for example, the above-mentioned “range A” is set. When detecting the slide speed, the speed detector 34 sends the information to the bed controller 19. Then, the bed control unit 19 determines the speed in the movement control of the bed 30 and the top board 15 based on the information on the slide speed detected by the speed detection unit 34. That is, the control of the moving speed of the bed 30 and the top 15 by the bed control unit 19 depends on the speed of the sliding operation of the bed operation unit 31 by the operator. For example, when the operator slides the bed operation unit 31 at a high speed, the bed control unit 19 moves the bed 30 and the top 15 at a high speed. At this time, the bed control unit 19 may perform control by roughly classifying speeds such as “high speed”, “medium speed”, “low speed”, and the like.

  FIG. 8 is a flowchart in the present embodiment.

(Step S11) (Same as Step S1 in the first embodiment)
The operator places the subject P on the top board 15. Then, the top plate position detection unit 33 detects the relative position of the top plate 15 with respect to the X-ray path. The detection of the top plate position is performed depending on the operation of the bed operation unit 31 by the operator. The table top position detection unit 33 may detect the table top position by operating the “top table position detection” button displayed on the bed operation unit 31 by the operator, or simply operate the table operation unit 31. It may be done automatically depending on.

(Step S12) (Same as Step S2 in the first embodiment)
Based on the top board position detected in step S1, the couch operating unit 31 displays a shootable range.

(Step S13) (Same as Step S3 in the first embodiment)
The operator checks the imageable range displayed on the bed operation unit 31. Then, by operating the bed operation unit 31, the “range A” to be photographed is touch-operated. (See Figure 3)
Further, the operator operates the bed operation unit 31 in order to perform bed movement control in the Y-axis direction. (See FIG. 5) Thereby, the operator performs alignment in the Y-axis direction.

(Step S14A)
The operation detection unit 32 detects the touch operation performed in step S <b> 13 and transmits the information of “range A” to the bed control unit 19.

(Step S14B)
The couch controller 19 controls the movement of the top board 15 based on the moving speed determined by the following method. There are, for example, the following three methods for determining the moving speed at this time.

(1) Depends on the operation of the “moving speed” button displayed on the bed operating unit 31 by the operator. This is because the “moving speed” displayed on the bed operating unit 31 as shown in FIG. ”Button or the like is operated to determine the moving speed of the bed 30 or the top board 15. Then, the bed control unit 19 controls the movement of the bed 30 or the top board 15 based on the moving speed determined by the operator.

(2) Depends on the speed of the slide operation of the bed operation unit 31 by the operator. The movement control is performed. For example, several types of movement speeds such as “high speed”, “medium speed”, and “low speed” are set in advance. If the speed of the slide operation of the bed operation unit 31 by the operator is within the range of γ (m / s) to γ ′ (m / s), the moving speed of the bed 30 or the top 15 such as “high speed” is set. To decide. Then, the bed control unit 19 performs movement control of the bed 30 or the top board 15 based on the speed of the slide operation by the operator.

(3) Depends on the distance between the “range A” operated in step S3 and the X-ray path. This is because the “range A” set by the operator and the X-ray path to which the X-ray is exposed Depending on the distance between the two, the couch controller 19 controls the movement of the top board 15. For example, if the distance is within the range of δ (cm) to δ ′ (cm), “high speed”, if the distance is within the range of ε (cm) to ε ′ (cm), “low speed”, etc. Determine the speed of movement. Then, the bed control unit 19 controls the movement of the top board 15 according to the speed determined depending on the distance.

  Note that δ ′> δ> ε ′> ε.

  The operator may move the top 15 by any one of these three methods. When it is desired to make an early diagnosis, it is preferable to move the top 15 by the method (2) or (3) instead of the method (1) after the “range A” is determined.

(Step S15)
Based on the “range A” detected in step S <b> 13, the couch controller 19 controls the movement of the top 15. At this time, the bed control unit 19 performs movement control of the top board 15 according to the movement speed determined in step S14. In addition, when the top plate 15 is moving, the operator can stop the movement of the top plate 15 by operating the bed operation unit 31. For example, as described above, the “stop button” may be displayed and the operator may stop the operation by performing a touch operation, or may be performed by a tap operation or a flick operation of the bed operation unit 31 by the operator. .

(Step S16) (Same as Step S6 in the first embodiment)
The bed control unit 19 controls the movement of the bed 30 and the top 15, and the subject P is inserted into the opening. Then, the X-ray control unit 28 performs X-ray exposure control in order to generate a diagnostic image of the subject P within the “range A” set in step S3.

(Step S17) (Same as Step S7 in the first embodiment)
The computer system 20 generates an image in the “range A” that has been exposed to X-rays in step S16. Then, the image display unit 27 displays the image.

  According to this embodiment, when the speed detection unit 34 provided in the bed 30 detects the speed of the slide operation of the bed operation unit 31 by the operator, the bed control unit 19 causes the table 15 according to the detected speed. The movement control is performed. That is, the operator can easily and intuitively control the moving speed of the top 15. Therefore, it is possible to improve usability in the medical device.

(Third embodiment)
The medical device according to this embodiment is different from the first embodiment and the second embodiment in that the bed operation unit 31 includes a fingerprint detection unit 35 and a fingerprint data storage unit 36.

  FIG. 9 is a block diagram of the bed 30 and the bed control unit 19 and a schematic diagram showing the bed operation unit 31 in the present embodiment.

  The fingerprint detection unit 35 is provided so as to be able to detect the fingerprint of the operator who operates the bed operation unit 31. The fingerprint detection unit 35 determines whether or not the bed operation unit 31 can be used according to the type of the detected fingerprint. As shown in FIG. 9B, the fingerprint detection unit 35 may be provided outside the bed operation unit 31 or may be provided in the bed operation unit 31. In this embodiment, an example provided outside the couch operating unit 31 will be described.

  The fingerprint data storage unit 36 stores the fingerprint data detected by the fingerprint detection unit 35.

  In operating the couch operating unit 31, the operator first places his finger on the fingerprint detecting unit 35. The fingerprint detection unit 35 detects the operator's fingerprint. At this time, the fingerprint detection unit 35 determines whether or not the detected fingerprint matches the fingerprint stored in advance in the fingerprint data storage unit 36. If they match, the fingerprint detection unit 35 permits the operator to operate the bed operation unit 31. On the other hand, when the detected fingerprint does not match the fingerprint stored in the fingerprint data storage unit 36, the fingerprint detection unit 35 makes the bed operation unit 31 inoperable. That is, the operator cannot control the movement of the bed 30 / top 15 in a state where his / her fingerprint is not stored in the fingerprint data storage unit 36. Therefore, a person who may perform bed / top control such as a doctor stores his / her fingerprint in the fingerprint data storage unit 36 in advance.

  Thereby, only a specific person can operate the bed / top. Therefore, an unsuitable bed / top operation by the subject P or the like can be prevented, and a safer diagnosis can be performed.

(Fourth embodiment)
The medical device according to the present embodiment is different from the first to third embodiments in that the bed operation unit 31 is movably provided.

  FIG. 10 is a schematic diagram illustrating an example of the bed operation unit 31 in the present embodiment.

  As shown in FIG. 10A, the bed operation unit 31 is provided on the side of the bed 30. Then, as shown in FIG. 10B, the couch operating unit 31 is provided so as to protrude from the couch 30 and to be arranged so as to be substantially parallel to the Z-axis direction. Further, the couch operating unit 31 has such a degree of transparency that the operator can confirm the position of the subject P.

  The operator performs positioning in the Y-axis direction with the couch operating unit 31 when the couch operating unit 31 having transparency is in the state of FIG. For example, the operator confirms the position of the subject P through the bed operation unit 31, and touches the bed operation unit 31 to set a point. Based on the setting, the couch controller 19 controls the movement of the couch 30 in the Y-axis direction (see FIG. 10C).

  Thereby, the operator can perform not only the positioning of the top plate 15 in the Z-axis direction but also the positioning of the bed 30 in the Y-axis direction simply and intuitively by touching the bed operating unit 31. Therefore, this embodiment can improve the usability of the medical device.

  The X-ray CT apparatus has been described above as an example of the medical apparatus, but the first to fourth embodiments are not limited to this. The medical apparatus provided with the bed operation unit 31 in the first to fourth embodiments can be applied as a bed in, for example, an MRI apparatus or a radiotherapy apparatus.
