Description

  The present invention relates to a radiation image information reading apparatus configured to erase radiation image information remaining after reading radiation image information stored and recorded on a stimulable phosphor panel held in a cassette.

  Conventionally, a radiation image using a stimulable phosphor panel that accumulates part of the irradiated radiation energy while emitting excitation light such as visible light according to the stored radiation energy. Information reading devices are known.

  The radiological image information reading device is, for example, a cassette loading unit in which a cassette holding a stimulable phosphor panel in which radiographic image information of a subject such as a human body is accumulated and loaded is loaded, and the stimulable phosphor panel is irradiated with excitation light. The reading unit reads the radiation image information and the erasing unit that erases the remaining radiation image information by irradiating the storable phosphor panel from which the radiation image information is read with erasing light. In addition, the stimulable phosphor panel that has been subjected to the erasing process is reused by being discharged to the outside while being held in the cassette (see, for example, Patent Documents 1 to 3).

  Here, the stimulable phosphor panel is formed by forming a stimulable phosphor layer on which radiation image information is recorded on a support, and in order to obtain a desired stimulated emission light, the stimulable phosphor panel is formed. It is necessary to correctly set the front and back of the cassette holding the body panel. Further, in order to remove the stimulable phosphor panel from the cassette or to correctly set the direction of the read radiographic image information, it is necessary to load not only the front and back of the cassette but also the loading direction.

  Therefore, in Patent Document 1, for example, a code storage element is disposed at a specific portion of a cassette, while a code reading unit that reads a code of the code storage element is disposed in a cassette loading unit, and the code reading unit is configured to transmit the code If it is not possible to read the code, or if a code that cannot be identified is read, it is determined that the cassette is in an abnormal state, and an error display etc. is displayed, and a technique to prevent the cassette from being taken into the device is proposed. is doing.

JP 2002-156716 A (paragraph [0198], FIG. 6) JP-A-6-43565 (FIG. 3) Japanese translation of PCT publication No. 2001-503880 (FIG. 2)

  However, in Patent Document 1, if an abnormality is detected in the cassette loading state, the cassette cannot be supplied into the apparatus to proceed with processing unless the operator corrects the state. In Patent Documents 2 and 3, the cassette loading state cannot be detected. Therefore, if there is a cassette in the wrong loading state, the process is interrupted there, or inappropriate processing is performed. In any case, unless the worker corrects the cassette loading state, there is a problem that a time loss due to the interruption of the process due to erroneous loading occurs.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a radiological image information reading apparatus that can retract a cassette in an abnormal state and efficiently perform a process on the cassette in a normal state. .

In order to achieve the above object, the present invention relates to a cassette loading portion in which a plurality of cassettes holding a stimulable phosphor panel in which radiation image information is accumulated and recorded, and the stimulable phosphor panel. A reading unit that irradiates excitation light and photoelectrically reads the obtained stimulated emission light to obtain the radiation image information; and radiation image information that remains after irradiating the stimulable phosphor panel with erasing light. In the radiation image information reading apparatus having an erasing unit for erasing,
A detection unit for detecting the state of the cassette;
An abnormal cassette housing section for housing the cassette in which an abnormal state is detected by the detection section;
A discharge mechanism for discharging the cassette in which an abnormal state is detected to the abnormal cassette housing unit;
It is characterized by providing.

  In this case, when an abnormal state of the cassette is detected by the detection unit, the ejection mechanism stores the cassette in the abnormal cassette storage unit, and therefore, it is obstructed by a defective cassette among the plurality of cassettes loaded in the cassette loading unit. Without being done, the next cassette can be quickly supplied to continue the process.

  Here, the cassette abnormal state includes a cassette loading state abnormality with respect to the cassette loading unit, a cassette registration state abnormality, or a storage phosphor panel held in the cassette being abnormal.

  The abnormal state of the cassette loading state is, for example, a state where the cassette is loaded on the front and back sides of the cassette loading part or up and down, or a state where the cassette is loaded out of a desired posture. The cassette cannot be supplied into the radiation image information reading apparatus, or appropriate reading processing and erasing processing cannot be performed on the stimulable phosphor panel. For example, since the specific part of the cassette is not arranged at a predetermined position of the cassette loading unit, the detection unit can detect an abnormality in the loading state.

  For example, the registration status of the cassette is abnormal when the storage phosphor panel before the radiation image information is recorded or the storage phosphor panel in which the radiation image information has already been read and the erasing process is completed is held. When an unregistered cassette is loaded, or when a cassette that is different from the registered cassette to be scanned is loaded, if there is such an abnormality, the desired radiographic image information is acquired. Or radiographic image information cannot be processed normally. Therefore, for example, the cassette is equipped with a storage phosphor panel and a barcode or IC chip that holds identification information for specifying the cassette, while the radiation image information reader is For example, the imaging information of the stimulable phosphor panel held in the cassette used for the radiographed radiograph information radiographing information is stored in hospital networks such as HIS (Hospital Information System) and RIS (Radiology Information System). The identification information detected by the detection unit from the barcode or the like of the cassette loaded in the cassette loading unit and the imaging registered in the radiation image information reading device From the information, it is possible to detect the registered state of the loaded cassette and detect the presence or absence of an abnormality.

  Abnormality of the dissociation state of the stimulable phosphor panel held in the cassette is, for example, when there is a malfunction in the cassette and the stimulable phosphor panel cannot be detached from the cassette, or when the cassette cannot be opened. If there is such an abnormality, it becomes impossible to perform normal reading processing or erasing processing on the stimulable phosphor panel. The detection unit can detect the presence or absence of an abnormal state based on, for example, whether or not the stimulable phosphor panel is detached from the cassette, or whether or not the cassette is opened.

  The abnormal cassette storage unit that stores the cassette in which the abnormal state is detected can be disposed in the cassette loading unit. In this case, an intake portion that takes in the cassette into the radiation image information reading device is disposed in the cassette loading portion, while a wall portion that moves from the intake portion is disposed, and an abnormal state of the cassette is detected by the detection portion. At this time, the cassette can be accommodated in the abnormal cassette accommodating portion by moving the wall portion while holding the cassette.

  In addition, the bottom surface of the cassette loading section where the capturing section is disposed is configured to be inclined, and the wall section is configured to be movable in the downward direction of the inclined bottom surface. While being able to be taken into the information reading apparatus, the cassette in which the abnormal state is detected can be held on the wall and moved to the abnormal cassette housing portion by its own weight.

  In addition, the cassette is taken into the apparatus regardless of whether there is an abnormality, and the cassette in which the abnormal state is detected is accommodated in the abnormal cassette accommodating part in the apparatus by the discharge mechanism, or the apparatus configured independently of the cassette loading part By accommodating in the outside abnormal cassette accommodating portion, it is possible to continue the processing for the cassette in the normal state.

  Furthermore, by disposing the normal cassette housing unit separately from the abnormal cassette housing unit, the cassette in which the abnormal state is detected and the cassette in the normal state can be reliably separated and housed.

  Furthermore, by loading a plurality of cassettes into the cassette loading unit and detecting the state of each cassette, the cassette in which the abnormal state is detected is accommodated in the abnormal cassette housing unit, while processing for the cassette in the normal state is performed. Can continue efficiently. In this case, the operator can move to another work without being restrained on the spot after loading a plurality of cassettes in the cassette loading unit.

  In the radiographic image information reading apparatus of the present invention, when there is an abnormality in the loading state of the cassette or the removal state of the stimulable phosphor panel accommodated therein, the cassette is retracted to the abnormal cassette housing portion and is in a normal state. Processing for the cassette can be continued. In this case, when a plurality of cassettes are loaded in the cassette loading unit, the processing on the cassette in a normal state can be efficiently performed, while the operator can quickly perform other operations without being bound by the cassette state. Can move on to work.

  First, the operator loads the cassette 12 that houses the stimulable phosphor panel 14 on which the radiation image information is accumulated and recorded in the loading box 50 of the cassette loading unit 38. In this case, the loading box 50 can be loaded with a plurality of cassettes 12 having different sizes at the same time. In the present embodiment, it is assumed that a maximum of five cassettes 12 can be loaded simultaneously.

  When the cassette 12 is loaded, the sensors S11 to S54 disposed on the bottom surface 52 of the loading box 50 detect the loading state of each cassette 12. The display parts 58a-58e display the loading state of each cassette 12 based on the detection information by the sensors S11-S54.

  Here, based on FIGS. 6-11, the determination method of the loading state of the cassette 12 is demonstrated.

  The cassette 12 has two types, a large-size cassette 12A having a width DA and a small-size cassette 12B having a width DB (DA> DB). The width D of the loading box 50 is the width DA of the large-size cassette 12A. Is set to be approximately equal to. In addition, the reflective marker 18 disposed at the end of each large-size cassette 12A and small-size cassette 12B has a width K and is arranged at a distance m from the side of each of the large-size cassette 12A and the small-size cassette 12B. Shall be established. Further, in the sensors S11 to S54 disposed on the bottom surface portion 52 of the loading box 50, the distance from the both sides of the loading box 50 is set to the distances d1 to d5 from the display portions 58a to 58e. .

  FIG. 6 shows a state in which the large-size cassette 12A is loaded in the loading box 50 so that the identification unit 22 and the like are in front and the opening 16 into which the stimulable phosphor panel 14 is inserted is at the top. . In this case, if the relationship m <d1 <m + K <d1 + d2 is set, only the sensor S11 (S21, S31, S41, S51) detects the reflective marker 18. Accordingly, it is detected that the large size cassette 12A is normally loaded, and the display units 58a to 58e corresponding to the positions of the loading box 50 in which the large size cassette 12A is loaded are lit in green, for example. The determination result indicating the normal loading state is displayed.

  FIG. 7 shows a state in which the large-size cassette 12A is loaded in the loading box 50 so that the identification unit 22 and the like are on the main body 44 side. In this case, if the relationship of m <d5 <m + K <d5 + d4 is set, only the sensor S14 (S24, S34, S44, S54) detects the reflective marker 18. Therefore, it is detected that the large size cassette 12A is in an abnormal loading state, and the display units 58a to 58e corresponding to the positions of the loading box 50 in which the large size cassette 12A is loaded are lit in red, for example. The determination result indicating an abnormal loading state is displayed.

  FIG. 8 shows a state in which the small-size cassette 12B is loaded in the loading box 50 in a state where the identification unit 22 or the like is in front and is brought close to the display units 58a to 58e. In this case, similarly to the large-size cassette 12A shown in FIG. 6, the determination result that the loaded state is normal can be known by the display units 58a to 58e.

  FIG. 9 shows a state in which the small-size cassette 12B is loaded in the loading box 50 in a state where the identification unit 22 and the like are in front and are separated from the display units 58a to 58e. In this case, only the sensor S12 (S22, S32, S42, S52) detects the reflective marker 18 if the relationship D-DB + m <d1 + d2 <D-DB + m + K <d1 + d2 + d3 is set. Therefore, it is detected that the small size cassette 12B is normally loaded, and the display portions 58a to 58e corresponding to the positions of the loading box 50 in which the small size cassette 12B is loaded are lit in green, for example. The determination result indicating the normal loading state is displayed.

  The width K of the reflective marker 18 is set to a predetermined width satisfying d2 <K, and at least one of the sensors S11 (S21, S31, S41, S51) or S12 (S22, S32, S42, S52) can detect the reflective marker 18. With this setting, even when the small-size cassette 12B is loaded in an arbitrary position of the loading box 50, it is possible to reliably detect that the loading state is normal.

  FIG. 10 shows a state in which the small size cassette 12B is loaded in the loading box 50 in a state where the identification unit 22 and the like are on the main body 44 side and are brought close to the display units 58a to 58e. In this case, if the relationship D-DB + m <d5 + d4 <D-DB + m + K <d5 + d4 + d3 is set, only the sensor S13 (S23, S33, S43, S53) detects the reflective marker 18. Accordingly, it is detected that the small size cassette 12B is in an abnormal loading state, and the display units 58a to 58e corresponding to the position of the loading box 50 in which the small size cassette 12B is loaded are lit in red, for example. The determination result indicating an abnormal loading state is displayed.

  FIG. 11 shows a state in which the small-size cassette 12B is loaded in the loading box 50 in a state where the identification unit 22 and the like are in front and are separated from the display units 58a to 58e. In this case, if the relationship of m <d5 <m + K <d5 + d4 is set, only the sensor S14 (S24, S34, S44, S54) detects the reflective marker 18. Accordingly, it is detected that the small size cassette 12B is in an abnormal loading state, and the display units 58a to 58e corresponding to the position of the loading box 50 in which the small size cassette 12B is loaded are lit in red, for example. The determination result indicating an abnormal loading state is displayed.

  The width K of the reflective marker 18 is set to a predetermined width satisfying d4 <K, and at least one of the sensors S14 (S24, S34, S44, S54) or S13 (S23, S33, S43, S53) can detect the reflective marker 18. With this setting, even when the small-size cassette 12B is loaded in an arbitrary position of the loading box 50, it is possible to reliably detect that the loading state is abnormal. Further, when the cassette 12 is loaded in the cassette loading unit 38 with the up / down or vertical / horizontal positions being wrong, since any of the sensors S11 to S54 cannot detect the reflective marker 18, it is determined that the loading state is abnormal. Can do.

  As described above, the loading state of the cassette 12 with respect to the cassette loading unit 38 can be detected. In this case, the operator can collectively perform correction work for the cassette 12 in an abnormal loading state as necessary.

  Here, in the above description, in order to detect the loading state of the cassette 12, the presence or absence of light reflected by the reflective marker 18 is detected by the sensors S11 to S54. However, for example, instead of the reflective marker 18, It is also possible to detect a loading state by arranging a barcode including identification information at a specific location of the cassette 12 and determining whether or not the barcode can be read by the barcode reader. In this case, if it is set as a restriction condition that the cassette 12 is loaded in the state where it is moved toward the display units 58a to 58e, the loading state of the cassette 12 is detected by the barcode reader provided only on the display units 58a to 58e side. can do. Further, if the barcode is read by scanning the laser beam over a wide range, it is possible to detect the loading state of the cassette 12 loaded in an arbitrary position of the loading box 50.

  Further, an RFID (Radio Frequency Identification), a magnetic sensor, an eddy current detection sensor, or the like can be used as the loaded state detection unit. In this case, for example, it is desirable to dispose a metal member that does not generate a magnetic field on the side of the cassette 12 that is used in the vicinity of the patient in order to eliminate the concern that a malfunction such as a pacemaker may occur.

  Furthermore, a mechanical detection unit such as a micro switch is provided on the loading box 50 side, and the detection state is loaded depending on whether or not a detection member such as a recess provided on the cassette 12 side is mechanically operated. Can also be configured to detect.

  The information relating to the loading state of the cassette 12 detected as described above is an external device connected to the radiation image information reading device 10, for example, a terminal device for inputting a patient ID or the like recorded in the cassette 12 It is also possible to notify the operator of the processing status in the radiation image information reading apparatus 10.

  Next, the cassette loading unit 38 drives the lid opening / closing motor 56 to rotate the lid member 54, and sequentially takes the cassettes 12 loaded on the lid member 54 into the radiation image information reading apparatus 10. In this case, since the bottom surface portion 52 constituting the cassette loading unit 38 is set to be inclined so that the lid member 54 side is downward, the cassette 12 sequentially moves to the lid member 54 side by its own weight, The image information is read into the image information reading apparatus 10. The lid member 54 holds the closed state of the lid member 54 when the loading state of the cassette 12 loaded in the cassette loading unit 38 is abnormal, thereby removing the cassette 12 in the abnormal state from the radiation image information reading device. It is possible not to be taken into the interior of 10.

  The cassette 12 taken into the radiation image information reading apparatus 10 is nipped and conveyed by the nip roller 86 and supplied to the first processing mechanism 62 that stands by in the first processing unit 70. In this case, after the identification information recorded in the identification unit 22 is read by the reading unit 93 of the first processing mechanism 62, the cassette 12 is supported at the lower end by the support members 88a and 88b (see FIG. 5).

  Here, when the cassette 12 is taken into the radiation image information reading apparatus 10 with the loading state being inappropriate, the identification information of the identification unit 22 cannot be read by the reading unit 93. It can also be determined that there is an abnormality.

  Further, based on the identification information read by the reading unit 93, it is determined whether or not radiation image information is recorded on the stimulable phosphor panel 14 accommodated in the cassette 12, and the cassette 12 is registered from the determination result. It is also possible to know the abnormal state.

  Next, when the pinion gear 94 is rotated, the rack members 92a and 92b are displaced, and the width adjusting plates 96a and 96b are moved close to each other, whereby the cassette 12 is positioned in the width direction. In this case, the position of the cassette 12 in the width direction is automatically adjusted inside the radiation image information reading apparatus 10 by the width adjusting plates 96 a and 96 b provided in the first processing mechanism 62. Therefore, the operator can load the cassette 12 into the cassette loading unit 38 without specially being aware of the loading position.

  After the cassette 12 is aligned, the support members 88a and 88b are displaced by a predetermined amount in the vertical direction along the connecting plates 90a and 90b in accordance with the size information read by the reading unit 93, so that the vertical positioning of the cassette 12 is performed. Done.

  After the cassette 12 in the normal loading state is positioned as described above, the first processing mechanism 62 conveys the cassette 12 to the second processing unit 72 while being guided by the guide members 66 and 68. To do. Next, when the solenoids 100a and 100b disposed on the upper portion of the first processing mechanism 62 are driven, the lock release pins 98a and 98b are inserted into the holes 34a and 34b of the cassette 12, and the locking leaf spring 30a. 30b is released. Next, the solenoids 91 a and 91 b disposed on the support members 88 a and 88 b of the first processing mechanism 62 are driven, whereby the discharge pins 89 a and 89 b are inserted into the holes 36 a and 36 b of the cassette 12. As a result, the stimulable phosphor panel 14 accommodated in the cassette 12 is exposed from the opening 16 to the top.

  In this case, when the detecting unit 121 disposed on the upper part of the second processing unit 72 detects the stimulable phosphor panel 14, it is determined that the stimulable phosphor panel 14 has been normally taken out from the cassette 12. Can do. Further, when the detection unit 121 cannot detect the stimulable phosphor panel 14, for example, there is an abnormality in the mechanism of the cassette 12, the operation of the solenoids 100a and 100b for releasing the lock of the stimulable phosphor panel 14, and the like. It can be determined that the phosphor panel 14 cannot be taken out. The determination result at this time can be notified to the operator via an external device, as in the case of the cassette loading unit 38.

  When the registration state of the cassette 12 is normal and the stimulable phosphor panel 14 is normally removed from the cassette 12, the nip roller 119 disposed on the upper portion of the second processing unit 72 is moved upward from the cassette 12. The protruding upper end of the stimulable phosphor panel 14 is gripped and supplied into the main body 44 via the shutter mechanism 116.

  On the other hand, the first processing mechanism 62 that holds the cassette 12 that has discharged the stimulable phosphor panel 14 to the main body 44 conveys the cassette 12 to the third processing unit 74 while being guided by the guide members 66 and 68. The second processing mechanism 64 having the grip plates 102a and 102b is waiting in the third processing section 74, and after the grip plates 102a and 102b grip both sides of the cassette 12, the support member of the second processing mechanism 64 is supported. The cassette 12 is transferred to the guide members 66 and 68 by the 88a and 88b retracting downward.

  The second processing mechanism 64 holding the cassette 12 moves to the third processing unit 74 and stands by. Further, the first processing mechanism 62 moves to the first processing unit 70 and performs processing for the next cassette 12 supplied from the cassette loading unit 38.

  The stimulable phosphor panel 14 supplied to the main body 44 is sub-scanned and conveyed upward by the reading conveyance path 120 and is main-scanned by the excitation light L output from the excitation light scanning unit 122. From the stimulable phosphor panel 14 irradiated with the excitation light L, stimulated emission light corresponding to the stored and recorded radiation image information is output. The stimulated emission light is guided to the photoelectric conversion unit 126 via the light collecting guide 124 and converted into an electric signal.

  The stimulable phosphor panel 14 from which the radiographic image information has been read is sandwiched by nip rollers 134 and 136 at the upper and lower portions, and is displaced by a predetermined amount in the horizontal direction by the panel transport unit 128 while being guided by the guide members 130 and 132. Next, the paper is conveyed downward by the nip rollers 134 and 136 via the shutter mechanism 118.

  An erasing unit 138 is disposed below the shutter mechanism 118, and the stimulable phosphor panel 14 sandwiched and conveyed downward by the nip rollers 140 and 142 is irradiated with erasing light from the erasing unit 138. The remaining radiation image information is erased. The stimulable phosphor panel 14 that has been erased is inserted from the opening 16 into the cassette 12 that stands by in the third processing unit 74.

  After the cassette 12 storing the stimulable phosphor panel 14 is conveyed to the fourth processing unit 76 by the second processing mechanism 64, the cassette 12 is displaced upward while being gripped by the gripping plates 102a and 102b. Next, the upper end portion of the cassette 12 is held by the nip roller 106 and is discharged to the storage box 110 of the cassette discharge portion 40 through the lid member 108. In this case, since the bottom surface portion 112 constituting the cassette discharge portion 40 is set to be inclined so that the side away from the lid member 108 is down, the discharged cassette 12 is moved by its own weight and is stored in the storage box. 110 is laminated.

  On the other hand, the cassette 12 in which the loading state is detected to be abnormal in the cassette loading unit 38, the cassette 12 in which the registration state is detected by the reading unit 93 of the first processing unit 70, or the second process. The cassette 12, which is detected by the detection unit 121 disposed on the upper part of the unit 72 to be unable to normally remove the stimulable phosphor panel 14, is thirdly processed by the second processing mechanism 64 constituting the cassette transport unit 42. It is conveyed to the fifth processing unit 77 via the processing unit 74 and the fourth processing unit 76. Next, the upper end portion of the cassette 12 is nipped by the nip roller 107 and is discharged and accommodated in the accommodation box 111 of the cassette accommodation portion 41 via the lid member 109. Since the bottom surface portion 113 constituting the cassette housing portion 41 is also set to be inclined, the discharged cassette 12 is moved by its own weight and stacked in the housing box 111.

  Therefore, the operator corrects the loading state of the cassette 12 discharged to the cassette accommodating portion 41 or repairs a defective portion of the cassette 12 or the radiographic image information reading apparatus 10 in any work, and then re-sets the cassette. The loading unit 38 can be loaded for processing. During this time, the radiation image information reading apparatus 10 can continue the processing for the cassette 12 in a normal state without interruption.
