Description

  The present invention relates to a radiographic image information recording apparatus including an imaging unit that captures radiographic image information of a subject and an elevating unit that holds the imaging unit so that the imaging unit can be elevated.

  Conventionally, when radiation (X-rays, α-rays, β-rays, γ-rays, electron beams, ultraviolet rays, etc.) is irradiated, a part of this radiation energy is accumulated, and then when irradiated with excitation light such as visible light, it is accumulated. By using a stimulable phosphor (stimulable phosphor) that exhibits stimulated luminescence according to the energy intensity, the radiation image information of a subject such as a human body can be reproduced on a photographic material or the like, or can be used for CRT, etc. A system that outputs a visual image is known.

  In the above system, specifically, a radiographic image information of a subject such as a human body is temporarily recorded (photographed) on a stimulable phosphor sheet having a sheet-like stimulable phosphor layer, and the stimulable fluorescence is recorded. A stimulating emission light is generated by irradiating the phosphor sheet with excitation light such as laser light, and a reading unit for photoelectrically reading the stimulating emission light, and radiation image information remaining on the stimulable phosphor sheet after reading And a so-called built-in radiation image information recording / reading apparatus (radiation image information recording apparatus) in which the storage phosphor sheet is incorporated in the apparatus.

A radiographic image information recording / reading apparatus is employed.

  By the way, in this type of radiographic image information recording / reading apparatus, a gripping rod for assisting a patient in a standing posture is provided on the side of an imaging unit (a device main body incorporating a radiation detector) that can be moved up and down. . This grasping bar has a function as a support in the lateral direction of the patient and a function to make it easier to image the lungs by opening, for example, the scapula in order to reliably image the imaging position of the patient.

  In this case, depending on the body shape, particularly the height, the patient may have difficulty grasping the stick. Further, since it is difficult for the patient to turn his hand sufficiently to the back of the imaging unit, for example, the scapula may not open.

  Therefore, in the radiographic image information recording apparatus disclosed in Patent Document 1, side gripping portions capable of gripping a subject at the time of photographing are provided on both sides of the photographing unit, and the side gripping portions are provided on the photographing unit. A side grip bar having a substantially L shape in side view is provided, and an intermediate grip bar is provided in the middle of the side grip bar. As a result, even for a subject having a short height, the side gripping portion can be easily grasped, and various imaging parts of the subject can be easily and reliably recorded.

JP 2004-174019 A

  By the way, in the above-mentioned patent document 1, when photographing a subject with a long arm, there is a possibility that the shoulder blade of the subject cannot be sufficiently opened. For this reason, for example, it is conceivable to set a large number of intermediate grip bars in accordance with the physique difference, but the side gripping portion becomes large and complicated.

  The present invention solves this type of problem, and with a small and simple configuration, it is possible to easily and reliably record various imaging regions without being affected by the body shape of a subject such as a patient. An object is to provide a radiation image information recording apparatus.

  The radiographic image information recording apparatus is provided in the imaging unit, and is provided with a positioning unit for positioning the subject with respect to the imaging unit, and a side grip provided on both sides of the imaging unit so that the subject can be gripped during imaging. And a gripper moving mechanism that varies the distance between the positioning part and the gripping position of the side gripping part by the subject by moving the side gripping part relative to the photographing part. Yes.

  Moreover, it is preferable that a positioning part has a jaw position control part which controls a subject's jaw position.

  Furthermore, it is preferable that the gripper moving mechanism includes interlocking means for operating the side gripper substantially symmetrically on both sides of the photographing unit.

  Furthermore, it is preferable that the gripping portion movable mechanism includes a gripping portion fixing means for restricting the movement of the side gripping portion disposed at an arbitrary position.

  Moreover, it is preferable that the gripping part moving mechanism includes an ascending / descending interlocking means for moving the side gripping part in conjunction with the ascending / descending operation of the photographing unit.

  Furthermore, it is preferable that the side gripping part swings with respect to the photographing part about a horizontal rotation axis that intersects the ascending / descending direction of the photographing part. In addition, it is preferable that the side gripping portion is provided with a buffer member for restricting collision with the photographing unit at an end portion that swings around the horizontal rotation axis.

  In the present invention, a side gripping part capable of gripping a subject such as a patient at the time of photographing is provided on both sides of the photographing part, and the side gripping part is movable with respect to the photographing part. Therefore, since the gripping position of the side gripping part is changed according to the physique of the subject, the physique difference can be absorbed well.

  Thereby, even for a subject with a long arm, the posture of the subject with the scapula open can be reliably set. For this reason, it is possible to easily and surely record various imaging parts of the subject without being affected by the height and body shape, and the configuration is simplified and economical.

  As shown in FIGS. 1 and 3, a chin rest (chin position regulating portion) 69, which is a positioning portion for positioning the patient H with respect to the photographing portion 14, is mounted on the upper portion of the photographing portion 14. .

  As shown in FIGS. 1, 3, and 4, on both sides of the imaging unit 14, side gripping units 70 that can be gripped by the patient H with both hands at the time of imaging are provided. The side gripping part 70 is provided with a substantially L-shaped side gripping bar 72 that is curved to the lower side of the photographing part 14 in a side view of the photographing part 14, and in the middle of the side gripping bar 72. A grip bar 74 is provided.

  The side gripping rod 72 extends from the upper side of the photographing unit 14 to the elevating unit 12 side, and then extends to the vertical portion 72a extending vertically downward and to the lower portion of the photographing unit 14. In addition, a horizontal portion 72b that is curvedly connected to the vertical portion 72a in an arc shape is integrally provided. The intermediate gripping rod 74 is integrally connected to the vertical portion 72a substantially parallel to the horizontal portion 72b.

  As shown in FIGS. 3 and 4, the side gripping portion 70 is swung (moved) in the direction of arrow B with respect to the shooting portion 14 between the photographing portion 14 and the side gripping portion 70. Thus, a gripper movable mechanism 76 that makes the distance between the jaw rest 69 and the gripping position of the side gripper 70 by the patient H variable is configured.

  As shown in FIG. 4, the gripper moving mechanism 76 includes a pair of upper and lower casings 78 a and 78 b that are fixed to the back surface 14 a of the photographing unit 14. In the casings 78a and 78b, support shafts 80a and 80b are arranged in parallel with the ascending / descending direction (arrow A direction) of the photographing unit 14, and the support shafts 80a and 80b constitute a vertical rotation shaft.

  Rotating members 82a and 82b are rotatably mounted on the support shafts 80a and 80b. The end of the vertical portion 72a constituting the side gripping rod 72 is fixed to the rotating member 82a, and the end of the intermediate gripping rod 74 is fixed to the rotating member 82b.

  At least one of the rotation member 82a and the rotation member 82b, for example, the rotation member 82a, the side gripping portion 70 is disposed in a desired angle posture with respect to the photographing unit 14, and then the side gripping portion A gripping portion fixing means 84 for restricting the movement of 70 is provided. Although this gripping part fixing means 84 is not shown in the figure, for example, it may be a structure that fixes the end of the support shaft 80a to the rotating member 82a, and a known structure such as a latch mechanism is adopted.

  As shown in FIG. 1, a power breaker switch 92 for turning on / off the apparatus power is provided on the lower side of the elevating unit 12, and the elevating of the photographing unit 14 is urgently stopped above the power breaker switch 92. An emergency stop switch 94 is provided. An operation panel 96 is attached to the upper portion of the elevating unit 12 so as to be tiltable in the vertical direction and the horizontal direction with respect to the mounting base 98.

  The operation panel 96 is provided with a device power switch 100 that activates the radiographic image information recording / reading device 10. A panel unit 102 disposed above the device power switch 100 has patient information, imaging size display, and selection. Utility operations etc. are displayed.

  A remote-controlled lift switch unit 106 is connected from the operation panel 96 through the cable 104. The elevating switch unit 106 is provided with an imaging unit elevating switch 108 for elevating the imaging unit 14.

  In addition, as shown in FIG. 1, the control part 110 is arrange | positioned adjacent to the raising / lowering part 12. As shown in FIG. The control unit 110 performs drive control of the entire radiation image information recording / reading apparatus 10.

  The operation of the radiation image information recording / reading apparatus 10 configured as described above will be described below.

  First, as shown in FIG. 2, when the patient H moves to the radiation recording unit 22 to record the radiation image information, an engineer or the like operates the imaging unit elevation switch 108 of the elevation switch unit 106 (FIG. 1). The recording position is adjusted such that the photographing unit 14 is moved up and down.

  The patient H places the chin on the chin rest 69 and is arranged corresponding to the imaging table 32 and grips the side gripping portion 70. In this state, the radiation source 30 is driven by an engineer or the like (see FIG. 2). The radiation output from the radiation source 30 passes through the patient H and reaches the stimulable phosphor sheet IP, whereby radiation image information is recorded on the stimulable phosphor sheet IP.

  After the radiation image information of the patient H is recorded on the stimulable phosphor sheet IP, the excitation system 36 that constitutes the reading unit 24 is driven, and the rotational drive source 50 that constitutes the sub-scanning system 26 is driven. In the excitation system 36, a plurality of laser diodes 44 arranged in the main direction (arrow X direction) of the stimulable phosphor sheet IP are driven, and the excitation light output from the laser diode 44 and reflected by the cylindrical mirror 46. L is applied to the stimulable phosphor sheet IP along the arrow X direction.

  On the other hand, when the drive pulley 54 rotates through the rotary shaft 52 under the drive action of the rotary drive source 50 that constitutes the sub-scanning system 26, the belt 58 that is stretched between the drive pulley 54 and the driven pulley 56. Under the circular running action, the scanner head 42 fixed to the belt 58 moves in the arrow Y direction. For this reason, the stimulable phosphor sheet IP in which the radiation image information is accumulated is scanned two-dimensionally by the excitation light L, and this stimulable phosphor sheet IP emits the stimulated emission light R corresponding to the radiation image information. To emit.

  This stimulated emission light R is incident on the CCD line sensor 40 via the condenser lens array 38. When the stimulated emission light R is incident on the CCD line sensor 40, the stimulated emission light R is converted into an electrical signal, and the radiation image information of the stimulable phosphor sheet IP is photoelectrically read.

  Next, the storable phosphor sheet IP from which the radiation image information has been read is irradiated with erasing light Q from a fluorescent lamp 68 constituting the erasing light source unit 28. Therefore, the radiation energy remaining on the stimulable phosphor sheet IP is released, and this stimulable phosphor sheet IP is used for the next imaging.

  In this case, in the first embodiment, as shown in FIGS. 1 and 3, side gripping portions 70 that can be gripped by the patient H at the time of photographing are provided on both sides of the photographing unit 14. The side gripping portion 70 includes a substantially L-shaped side gripping rod 72 in a side view of the photographing unit 14, and the vertical gripping portion 72a of the side gripping rod 72 is vertically moved along the horizontal portion 72b. It can be arbitrarily held in the direction and the front-rear direction.

  For this reason, for example, the patient H can support the independence from the wheelchair, can easily take the posture of extending the arm to the back of the imaging unit 14, and can be gripped with either forward or reverse hands. There is no restriction of posture. Moreover, since the intermediate grip rod 74 is provided, the intermediate grip rod 74 can be gripped even by, for example, a patient H who is short in height (see FIG. 5).

  Further, as shown in FIGS. 3 and 4, the side gripping portion 70 is configured to be swingable in the arrow B direction with respect to the photographing unit 14 via the gripping portion movable mechanism 76. For this reason, in a patient H having a standard arm length, the side gripping rod body of the side gripping portion 70 in a state where the side gripping portion 70 is arranged in the angular posture shown in FIG. 72 or the intermediate gripping rod 74 is gripped.

  On the other hand, in particular, in the patient H with long arms, when the side gripping portion 70 is arranged at the position shown in FIG. 3, the shoulder blade of the patient H is surely secured when the side gripping portion 70 is gripped. It becomes difficult to open.

  Therefore, in the first embodiment, as shown in FIG. 4, first, the fixing action of the support shaft 80a by the gripping portion fixing means 84 is manually or automatically released. Next, for example, the patient H grips the vertical portion 72a of the side gripping bar 72 and moves the side gripping bar 72 away from the patient H (in the direction of arrow B1 in FIG. 4). .

  Therefore, in the side gripping portion 70, the rotating members 82a and 82b to which the vertical portion 72a and the intermediate gripping rod 74 are fixed swing in the direction of the arrow B1 with the support shafts 80a and 80b as fulcrums. Therefore, the distance between the jaw rest 69 and the gripping position of the side gripping portion 70 by the patient H is increased, and the scapula of the patient H can be reliably opened. In this state, the gripping portion fixing means 84 is driven and the support shaft 80a is fixed to the rotating member 82a, so that the side gripping portion 70 has a desired angle corresponding to the length of the arm of the patient H. Held in position (see FIG. 6).

  As a result, the patient H can be easily grasped at any part of the side gripping portion 70 without being affected by the body shape, and is photographed with the scapula reliably opened. For this reason, the effect that it becomes possible to record various imaging | photography site | parts of the patient H easily and reliably is acquired.

  In addition, the side gripping portion 70 only needs to be configured to be swingable about the vertical axis with respect to the photographing unit 14, and the configuration is simplified and economical. Moreover, the side gripping portion 70 is fixed by the gripping portion fixing means 84 at the time of shooting or when the preparation for shooting is completed. Accordingly, the side gripping portion 70 does not move unnecessarily during imaging, and the imaging posture of the patient H can be prevented from being lost.

  On the other hand, after photographing, the side gripping portion 70 is released from being fixed by the gripping portion fixing means 84. For this reason, the impact when the patient H releases his / her hand from the side grip 70 is prevented from being transmitted to the imaging unit 14. Thereby, even if the reading process of the radiation image information is performed in the imaging unit 14, a good read image can be obtained.

  FIG. 7 is a perspective explanatory view from the back surface 122a side of the imaging unit 122 constituting the radiographic image information recording / reading apparatus 120 according to the second embodiment of the present invention.

  The same components as those in the radiation image information recording / reading apparatus 10 according to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Similarly, in the third to fifth embodiments described below, detailed description thereof is omitted.

  In the second embodiment, a gripping portion movable mechanism 124 that swings the side gripping portion 70 with respect to the photographing portion 122 in the arrow B direction is provided between the side gripping portion 70 and the photographing portion 122. It is done. The gripper movable mechanism 124 includes a motor 126, and a rotating member 82b is fixed to a rotating shaft 126a extending from the motor 126 in the direction of arrow A. An encoder 128 is connected to the motor 126 and detects the swing position of the side gripping portion 70 in the direction of arrow B.

  In the second embodiment configured as described above, for example, the motor 126 is driven in a state where the patient H holds the side gripping portion 70. Then, after the patient H is placed in a desired gripping posture, the drive of the motor 126 is stopped. Thereby, the patient H is not affected by the body shape, and the same effects as those of the first embodiment can be obtained, for example, the patient H can be photographed with the scapula reliably opened.

  In the second embodiment, the motor 126 can be automatically driven in conjunction with the raising / lowering operation of the photographing unit 122. That is, in the patient H who is tall and has a long arm, in order to raise the imaging unit 122, the side gripping unit 70 is swung in the arrow B1 direction when the imaging unit 122 is raised. On the other hand, when lowering the imaging unit 122 corresponding to a patient H who is short and has short arms, the side gripping unit 70 is swung in the direction of arrow B2.

  As a result, the side gripping portion 70 is automatically swung in accordance with the standard physique of the patient H when the imaging unit 122 is raised and lowered, so that the adjustment time of the side gripping portion 70 is effectively shortened. The effect is obtained.

  FIG. 8 is an explanatory perspective view of a radiographic image information recording / reading apparatus 130 according to the third embodiment of the present invention, and FIG. 9 is a schematic plan view of an imaging unit 132 constituting the radiographic image information recording / reading apparatus 130. FIG.

  The photographing unit 132 is provided with a gripping unit movable mechanism 134 that swings and displaces the side gripping unit 70 with respect to the photographing unit 132. The gripper movable mechanism 134 is a link piece 136a, 136b that is swingably connected to each horizontal part 72b that constitutes the side gripping rods 72 on the left and right sides, and the link pieces 136a, 136b that are swingably connected. A connecting link piece (interlocking means) 138.

  A rack 140 extending in the thickness direction (arrow C direction) of the imaging unit 132 is fixed to the connecting link piece 138, and a pinion 142 is engaged with the rack 140. The pinion 142 is rotatably supported in the photographing unit 132.

  Stopper portions 144a and 144b protrude downward at the lower ends of both ends in the longitudinal direction of the rack 140 and have a taper at the lower end. Below the stopper portions 144a and 144b, a fixing member 148 that constitutes the gripping portion fixing means 146 is disposed so as to be movable up and down via the solenoid 150. A plurality of recesses 152 are formed on the upper portion of the fixing member 148 so as to be spaced apart from each other by a predetermined interval, and the acute ends of the stopper portions 144a and 144b are engageable with the recess 152.

  In the third embodiment configured as described above, first, the solenoid 150 constituting the gripping portion fixing means 146 is driven, the fixing member 148 moves downward, and the stopper portions 144a and 114b are detached from the recess 152. Let me. Next, when the patient H constitutes the side gripping portion 70, for example, grips the side gripping rod 72 and swings it in the direction of arrow B, the patient H is connected to the horizontal portion 72b of each side gripping portion 70. The link pieces 136a and 136b are swung, and the connecting link piece 138 connected to the link pieces 136a and 136b moves in the direction of the arrow C1 under the guiding action of the rack 140 and the pinion 142 (see FIG. 10).

  Then, after the position of the side gripping portion 70 is adjusted to an optimal position with respect to the patient H, the solenoid 150 constituting the gripping portion fixing means 146 is driven, and the fixing member 148 is raised. Accordingly, the stopper portions 144a and 144b are fitted into the arbitrary concave portions 152 of the fixing member 148, and the side gripping portion 70 is fixed.

  In this state, the imaging operation of the radiation image information of the patient H is performed as described above. At that time, the side gripping portion 70 gripped by the patient H is fixed via the gripping portion fixing means 146, and the side gripping portion 70 moves unnecessarily at the time of photographing, so that the photographing posture of the patient H is changed. Fluctuation can be prevented.

  After the imaging of the radiation image information of the patient H is completed, the fixation of the side gripping part 70 is released under the driving action of the gripping part fixing means 146. For this reason, the impact when the patient H releases his / her hand from the side grip 70 is difficult to be transmitted to the imaging unit 132. Therefore, it is possible to reliably obtain a highly accurate read image without affecting the reading operation of the radiation image information in the imaging unit 132.

  Furthermore, in the third embodiment, the left and right side grip bars 72 and the intermediate grip bars 74 are connected to link links 138 as link means and link pieces 136a and 136b connected to the link links 138. The operation of the substantially left and right objects can be performed. Accordingly, there is an advantage that the posture of the patient H at the time of photographing is maintained symmetrically and the photographing process is performed with high accuracy.

  FIG. 11 is a perspective explanatory view of a radiation image information recording / reading apparatus 160 according to the fourth embodiment of the present invention.

  The imaging unit 162 constituting the radiation image information recording / reading device 160 is configured such that the side gripping unit 70 is movable via a gripping unit movable mechanism 164. The gripper movable mechanism 164 includes a lifting / lowering interlocking means 166 in addition to the configuration of the gripper movable mechanism 134 applied to the third embodiment.

  The ascending / descending interlocking means 166 includes a rack member 168 extending in the direction of arrow A along the ascending / descending portion 12, and a predetermined number of, for example, two gears 170 (gear trains) are provided between the rack member 168 and the pinion 142. ) Is disposed.

  In the fourth embodiment configured as described above, when the photographing unit 14 moves up along the lifting unit 12 (see the direction of arrow A1 in FIG. 11), the rack member 168 and the gear provided in the lifting unit 12 170, the pinion 142 rotates to move the rack 140 in the direction of arrow C1. For this reason, the side gripping part 70 is oscillated and displaced in a direction away from the patient H with respect to the imaging part 162.

  On the other hand, when the photographing unit 14 moves vertically downward along the elevating unit 12, the rack 140 moves in the direction opposite to the arrow C1 direction via the ascending / descending interlocking means 166. Accordingly, the side gripping portion 70 is oscillated and displaced toward the patient H side.

  As a result, when the imaging unit 162 moves up and down in accordance with the physique of the patient H, the side gripping unit 70 swings in the direction of the arrow B under the action of the lifting / lowering interlocking unit 166, and the optimum according to the patient H The effect that a proper gripping position can be automatically adjusted is obtained.

The shaft 186 constitutes a horizontal rotation shaft that intersects the ascending / descending direction of the photographing unit 182, and each side gripping rod 72 can swing in the direction of arrow D with the shaft 186 as a fulcrum.

  The horizontal portion 72b provided on the lower side of each side gripping rod 72 is provided to restrict the horizontal portion 72b from colliding with the photographing unit 182 when the side gripping portion 183 swings in the direction of arrow D. A buffer member, for example, a cylindrical sponge 188 is provided.

  The shaft 186 is provided with a gripping portion fixing means 190 for holding the side gripping portion 183 at a predetermined swing angle position. As the gripping part fixing means 190, for example, a known technique such as a latch mechanism can be adopted.

  In the fifth embodiment configured as described above, the patient H grasps the vertical portion 72a (or the intermediate grasping rod 74) constituting the side grasping portion 183, and the patient's H scapula opens. Then, the side gripping part 183 is caused to swing. Then, after the imaging posture of the patient H is obtained, the imaging processing of the patient H is performed in a state where the side gripping part 183 is held at a predetermined swing angle position via the gripping part fixing means 190.

  After the imaging is finished, the holding of the side gripping part 183 by the gripping part fixing means 190 is released, and the patient H releases the gripping of the side gripping part 183.
