Description

  The present invention relates to a radiation image reading apparatus used in a small-scale diagnostic system mainly used in a small-scale medical facility.

  Conventionally, technicians can take images of patients to be examined and provide them for diagnosis using image generation devices such as CR (Computed Radiography) and FPD (Flat Panel Detector) devices. A diagnostic system is known in which image processing such as gradation processing is performed so that an image processed image is output and provided for interpretation by a doctor.

  Such a diagnostic system was able to receive the patients who came to the hospital and issue the imaging order (acceptance), actually take the patient in the imaging room and generate the image data (engineer), the gradation, etc. Responsible for determining the availability of image diagnosis, and in some cases, responsible for correcting contrast and density (such as an engineer appointed from a general engineer), and interpreting in charge of determining (diagnosing) the presence or absence of disease based on images ( A plurality of persons in charge, such as doctors, share roles and diagnoses are advanced.

  In a large-scale medical facility (hereinafter referred to as a large-scale facility) where application of a conventional diagnosis system is assumed, there are a plurality of image generation apparatuses and engineers who operate the image generation apparatus. A console for operation and a viewer for checking image data by a doctor or the like are also provided separately with respective roles. For this reason, there is a possibility that the patient and the image data are mistaken. Therefore, in order to prevent this, a system has been proposed in which each device is linked through a network, an ID is issued in each device, and the results of work processes performed in each device are associated with each other (for example, patents). Reference 1).

  In such a system, the locations in charge of each of the above roles are often located in large hospitals such as the reception floor 1F and the radiology department underground, and multiple patients within the radiology department. The situation where a plurality of engineers use a plurality of imaging devices to perform imaging simultaneously is stationary, and a plurality of patients are constantly staying in each process, and the generated images and individual patients are In order to ensure that there is no mistake in the mapping, an ID is assigned to each work in each process, via a network of HIS (Hospital Information System) or RIS (Radiology Information System). The association is performed (see, for example, Patent Document 2 and Patent Document 3).

  For example, at the 1F reception desk, the examination content (imaging content) is determined based on the patient's main complaint and is registered together with the patient name. Thereby, a patient list as shown in FIG. 10A is created. The above patient list is added at any time and displayed on the 1F reception workstation (hereinafter referred to as “WS”). At the same time, the above patient list is stored in the radiology department of B1 via a network such as RIS / HIS (here, “console” is in the radiology department, setting of radiographing conditions and RIS / HIS radiographing order). This is a workstation that displays information and images of patients. In order to increase the efficiency of distributed processing, a plurality of consoles are usually provided, but these are also connected to each other via a network, and a predetermined inspection ID is selected at an arbitrary console. In order to prevent duplicate shooting among multiple technicians, a method of notifying that the patient list is being processed (flushing display, changing color, or beep warning if the same examination is specified, etc.) Used.

  A radiology engineer uses a console close to him / her, selects an examination ID to be taken from the displayed patient list, and registers an ID (cassette ID) of a CR plate (cassette) to be used. As a result, the cassette ID registered in the “cassette ID” field of the patient list is displayed as shown in FIG. An engineer, for example, takes three cassettes and moves to the imaging room to take an image of the patient. Thereafter, the photographed cassette is read by a reader. The reading device reads the cassette ID attached to the inserted cassette, attaches it to the image data and transmits the cassette ID, and finally the correspondence between the examination ID (patient ID) and the generated image data is attached. . The generated image data is transmitted to the console where the engineer has selected the examination ID, and displayed on the console. At this stage, the imaging positioning is confirmed. If the positioning is poor, the imaging is performed again, and it is also determined whether or not to apply density and contrast correction and frequency enhancement processing. Thereafter, the image is stored in a server waiting for interpretation (waiting for diagnosis). An image interpretation doctor extracts and displays an image related to a predetermined patient from an image stored in the image interpretation waiting server on a workstation in an image reading room (often equipped with a high-definition monitor for a viewer function). (Diagnosis) is performed.

  In a system used in such a large-scale facility, for example, whether the imaging performed on the patient is a simple imaging or a contrast medium imaging, the information that affects the insurance score calculation, such as the patient's examination ID or By registering a cassette ID or the like and associating a patient with a captured image, all information can be linked together and managed in a RIS / HIS server or the like.

  However, according to a survey by the inventors of the present application, in the case of a relatively small medical facility such as a medical practitioner or a clinic (hereinafter referred to as a small-scale facility), the number of installed image generating devices is small, and the assistant is the patient. In many cases, the doctor performs positioning, receives a notification of the completion of positioning from the assistant, and the doctor controls the X-ray exposure switch, or the doctor himself performs all operations including patient positioning.

  Also, for example, in the case of a large-scale facility, it is assumed that the patient has to travel between multiple floors in the facility after taking a picture until receiving a doctor's diagnosis. In some cases, since the facilities are small, the distance traveled by the patient after taking a picture until receiving a doctor's diagnosis is short.

  Under these circumstances, it is difficult to think of a mistake in taking a captured image with that of another patient. Using a system similar to a large-scale facility, it is necessary to generate imaging order information that begins with the input of the patient's name. On the contrary, the procedure becomes complicated and the medical efficiency is poor.

  In addition, in order to generate imaging order information such as patient information and examination information of a patient in advance and associate the imaging order information with a captured image, each device is connected with a network corresponding to a core system such as RIS / HIS. A system that can be connected is required. However, the construction of such a system is also costly, and there is a problem that it becomes a burden for small-scale facilities. Further, even if the number of devices is reduced while maintaining the above-described configuration concept in a large-scale facility, it is not optimal for a small-scale facility.

  Therefore, in Patent Document 4, as a system for a small-scale facility such as a practitioner or a clinic, an information input / output device arranged in an examination room and a radiological image information reading device in a radiographing room are connected via a network. A system for transmitting patient ID information and imaging information input by a doctor from an input / output device to a radiation image reading apparatus and displaying the ID information and imaging information of a patient to be imaged on a display unit of the radiation image reading apparatus is described. Has been.

Patent Document 5 sequentially inputs information related to imaging such as patient information and examination information, stores information related to a plurality of imaging in the input order, and stores information related to imaging to the radiation reader in the stored order. When the medical terminal to be transmitted and the recording medium on which imaging has been performed are set in accordance with the order received from the medical terminal, the radiographic image recorded on the recording medium is read to generate image data, and the generated image data And a radiographic image reading apparatus that associates the radiographing information with the radiographing information and transmits them to a medical terminal. Further, Patent Document 5 does not have a function of associating the read image data with information related to imaging in the radiation image reading device, and the radiation image reading device transmits the read image data to the medical terminal, In the medical terminal, the image data received from the radiation image reading apparatus is stored in the memory in association with the time data, and the operator confirms the time when the image data is received, and the image data, patient information, and examination A radiographic imaging system that associates information and the like is described.
US Pat. No. 5,334,851 JP 2002-159476 A JP 2002-311524 A Japanese Patent Laid-Open No. 2005-265943 JP 2005-342195 A

  However, in the system described in Patent Document 4, even in the case of an urgent patient, it is also a case of a re-photographed patient who only needs to take the same image as the previous time without receiving a doctor's inquiry. However, imaging cannot be performed without waiting for the input of imaging information by a doctor. In particular, when doctors are examining other patients, nurses and radiographers cannot enter the room from the viewpoint of personal information protection, and it is difficult to request the issuance of radiographing information. This is not preferable.

  Further, in Patent Document 5, a system that includes both the radiation image reading device in the former system and the radiation image reading device in the latter system configuration, and uses the latter radiation image reading device in an emergency. However, it is necessary to separately provide a radiological image reading device for emergency use and other purposes, and the above-mentioned problem cannot be solved by a single radiographic image reading device.

  The present invention inputs imaging order information at a medical terminal provided in an examination room and transmits it to a radiological image reading apparatus, and the radiographic image reading apparatus associates the read image data with the receiving order of the imaging order information. In a small-scale diagnostic system that transmits to a terminal for use, it is possible to start imaging and reading quickly without waiting for input of imaging order information in an emergency or the like.

  The radiographer performs imaging of the patient in the imaging apparatus 201 according to the imaging order information displayed on the display unit 23, attaches the imaged cassette to the reading apparatus 202, and reads the radiation image information recorded in the cassette. I do.

  In the reading device 202, when a photographed cassette is mounted (step S9), the image generation unit 27 reads the radiation image information recorded on the mounted cassette and generates image data (step S9). In S10, a reduced image (thinned image) is generated based on the read image and displayed on the display unit 23 (step S11). When the photographer confirms the image and the NG button of the operation unit 22 is pressed due to improper positioning (step S12; NO), the process returns to step S8, and re-photographing is performed. Steps S8 to S11 are executed. When the OK button of the operation unit 22 is pressed (step S12; YES), the imaging order information displayed in step S8 is associated with the read image data (for example, written in the header portion of the image data). (Step S13) and transmitted to the control device 3 via the communication unit 24 (Step S14).

  In the control device 3, when the image data is received via the communication unit 36, the received image is stored in the temporary storage unit 331 (step S15).

  In the reading device 202, when the transmission of the generated image data is completed, the imaging order information stored in the imaging order information storage unit 261 in the head order is deleted (step S16). Next, it is determined whether there is information stored in the imaging order information storage unit 261. If it is determined that the information is stored (step S17; YES), the process returns to step S8, and the next imaging order is stored. Photographing is performed according to the information. If there is no information stored, the process ends.

  When the imaging is completed, the patient moves to the examination room 13. By operating the input unit 34 of the control device 3, the doctor displays an image search screen (not shown) on the display unit 35 and inputs patient information of the target patient. In the control device 3, an image search screen is displayed according to the operation of the input unit 34, and patient information input is received via the input unit 34. When an image search screen is displayed and patient information is input from this screen via the input unit 34 (step S18), image data associated with imaging order information including the input patient information of the patient is temporarily stored. The extracted image data is subjected to image processing such as gradation processing and frequency emphasis processing, and a thumbnail image is generated by reducing the image processed image data. The captured image display screen of the display unit 35 It is displayed at 352 (step S19).

  FIG. 8 shows a display screen example of the captured image display screen 352 displayed on the display unit 35. As shown in FIG. 8, the captured image display screen 352 includes image display fields 352a to 352d for displaying a list of extracted images. When any one of the image display fields 352a to 352d is selected by the mouse or the like of the input unit 34, the selected image is displayed alone in the life size. Using this single display image, the doctor can observe the details of the image and make an interpretation diagnosis. An image processing adjustment field 352e is provided on the upper right of the screen, and the doctor can adjust the density and contrast by operating the image processing adjustment field 352e with a mouse or the like. When the OK button 352h displayed corresponding to each image is pressed, the displayed image can be determined as an image to be stored in the image DB 40. The captured image display screen 352 is provided with a patient information display field 352f that displays patient information included in the imaging order information associated with the displayed captured image.

  After image processing adjustment and image confirmation are performed from the captured image display screen 352 via the input unit 34 (step S20), the diagnosis end button on the captured image display screen 352 is pressed by the input unit 34. When the end of diagnosis is instructed (step S21; YES), image data and imaging order information corresponding to the displayed image are transmitted to the server 4 via the communication unit 36 and stored in the image DB 40 ( Step S22). The image data written in the image DB 40 of the server 4 is deleted from the temporary storage unit 331 (step S23).

  As described above, in the small-scale diagnosis system 1, when a doctor inputs imaging order information in the control device 3, the imaging order information is transmitted to the reading device 202 and displayed on the display unit 23. The photographer performs photographing according to the photographing order information displayed on the display unit 23 and attaches the cassette that has been photographed to the reading device 202. In the reading device 202, an image is read from the attached cassette to generate image data, and the generated image data is associated with the imaging order information displayed on the display unit 23 and transmitted to the control device 3. The In the control device 3, the received image data is displayed, image diagnosis is performed, and stored in the server 4.

  Note that, in a case where photographing is crowded, photographing order information may be transmitted from the control device 3 while photographing with the reading device 202 for the previous patient. In such a case, the received imaging order information is stored in the imaging order information storage unit 261 in association with a number indicating the reception order. The display unit 23 displays the shooting order information stored in the first order among the shooting order information stored in the shooting order information storage unit 261, and shooting is performed according to the displayed shooting order information. When the cassette is already mounted on the reading device 202, the cassette is read to generate image data, and the generated image data is associated with the shooting order information stored in the head order. It is transmitted to the control device 3. When the image data is transmitted to the control device 3, the first imaging order information displayed on the display unit 23 is deleted from the imaging order information storage unit 261, and the next imaging order information is displayed on the display unit 23. In this way, photographing and reading are sequentially performed. In the control device 3, the image data transmitted by the reading device 202 is displayed and used for diagnosis by a doctor.

  In the normal processing flow described above, in order to perform imaging and reading, it is necessary to receive input in the receiving device 5 and issue imaging order information by a doctor in the control device 3. However, in the normal processing flow, even in the case of an urgent patient, or in the case of a re-photographed patient who only needs to take the same image as the previous one without receiving a doctor's interview, the doctor Shooting cannot be performed without waiting for the issuance of shooting order information. In particular, if the doctor is examining another patient, the nurse will not be able to enter the room from the viewpoint of personal information protection, or it will be difficult to request an imaging order. It is not preferable.

  Therefore, in the present embodiment, the reading device 202 controls the reading of the attached cassette by the reading control process shown in FIG. It is possible to perform photographing and reading. When the interrupt button is pressed, ON is set in the interrupt flag area 251 of the RAM 25, and reading of the cassette mounted next in the reading device 202 is performed in the interrupt mode.

  Hereinafter, a reading control process executed by the CPU 21 of the reading device 202 will be described. This process is a process realized by software processing by the cooperation of the CPU 21 and the storage unit 26.

  When a cassette is attached to the image generation unit 27 (step S101; YES), the imaging order information storage unit 261 is referred to, and it is determined whether imaging order information is received from the control device 3. When it is determined that the imaging order information received in the imaging order information storage unit 261 exists (is stored) and the imaging order information is received from the control device 3 (step S102; YES), an interrupt flag The area 251 is referred to, and it is determined whether or not the interrupt mode is set. If it is determined that the interrupt mode is not set (step S103; NO), the radiographic image information recorded in the attached cassette is read to generate image data (step S104), and the generated image Is thinned and displayed on the display unit 23 (step S105). When the photographer confirms the image displayed on the display unit 23 and the NG button is pressed due to improper positioning or the like (step S106; NO), this process ends. On the other hand, when the OK button is pressed (step S106; YES), the imaging order information stored in the imaging order information storage unit 261 in the head order in the header portion of the generated image data (that is, the reception order is changed). First, the imaging order information displayed on the display unit 23 is written to associate the image data with the imaging order information (step S107), and the image data associated with the imaging order information is transmitted to the communication unit. 24 is transmitted to the control device 3 (step S108). Then, the image data stored in the first order in the imaging order information storage unit 261 is deleted (step S109), and this process ends.

On the other hand, in step S102, when the received imaging order information is not stored in the imaging order information storage unit 261, that is, when it is determined that the imaging order information is not received from the control device 3 (step S102; NO), Alternatively, when it is determined that the interrupt mode is set (step S103; YES), the flow after step S110 is executed. That is, the radiographic image information recorded on the attached cassette is read to generate image data (step S110), and the generated image is thinned and displayed on the display unit 23 (step S111). When the photographer confirms the image displayed on the display unit 23 and the NG button is pressed (step S112; NO), this process ends.
On the other hand, when the OK button is pressed (step S112; YES), information (for example, a specific code such as 9999) indicating that it has been read without photographing order information is written in the header portion of the generated image data. As a result, information indicating that the image data has been read without photographing order information is associated (step S113) and stored in the HDD 28 (step S114). When the transmission button of the operation unit 22 is pressed and transmission of image data is instructed (step S115; YES), the process proceeds to step S117. On the other hand, if the transmission button has not been pressed (step S115; NO), it is determined whether or not a preset reference time has elapsed since the save, and it is determined that a preset reference time has elapsed. (Step S116; YES), the process proceeds to Step S117. In step S116, the image data stored in the HDD 28 is transmitted to the control device 3 by the communication unit 24 (step S117), the interrupt flag area 251 is initialized (step S118), and this process ends.

  In the control device 3, when image data associated with information indicating that reading is performed without the imaging order information is received from the reading device 202, the image data is temporarily stored in the unregistered data storage unit 332. . Here, since imaging order information is not associated with image data, that is, patient information is not associated, it is desirable to associate image data with patient information immediately after reception. Since the association between the image data and the patient information is performed in response to an operation by the doctor, it is necessary to transmit when the doctor is not examining another patient and is ready to perform the association operation. is there. Therefore, the imaging operator inquires of the doctor about the transmission timing of the image data and presses the transmission button of the operation unit 22 to transmit the image data. In the case of a small-scale medical facility, the examination time for one patient is limited and does not exceed a certain time (reference time). Therefore, this reference time is set in the reader 202 in advance and stored in the HDD 28. The image data may be automatically transmitted to the control device 3 when the reference time or more has elapsed since the storage.

  In the control device 3, diagnosis of image data captured without imaging order information and association of patient information are performed as follows, for example.

  When the input unit 34 instructs the display of the image data stored in the unregistered data storage unit 332, a captured image display screen 353 (not shown) is displayed. The photographed image display screen 353 is substantially the same as the photographed image display screen 352 shown in FIG. 8, but images stored in the unregistered data storage unit 332 are displayed in the columns corresponding to the image display columns 352 a to 352 d. The captured image of the data is displayed, and the column corresponding to the patient name column 352f is an input column (patient information input column) for inputting the patient name corresponding to the displayed captured image. On this screen, after inputting patient information, adjusting the image, confirming the image, performing image diagnosis, and pressing the diagnosis end button, the image data of the captured image displayed on the screen In the header area, patient information is attached, and image data attached with the patient information is transmitted to the server 4 and stored in the image DB 40. The image data transmitted to the server 4 is deleted from the unregistered data storage unit 332.

  As described above, according to the reading device 202 of the small-scale diagnostic system 1, when a cassette is attached to the image generation unit 27, it is determined whether or not imaging order information is received from the control device 3. If it is determined that the interrupt mode has been set, the interrupt flag area 251 is referenced to determine whether the interrupt mode is set (a switching signal is output). If it is determined that the interrupt mode is not set, the radiographic image information recorded in the attached cassette is read to generate image data, and the imaging order information storage is performed in the header portion of the generated image data. The imaging order information stored in the first order in the unit 261 is associated by being written, and image data in which the imaging order information is associated is transmitted to the control device 3 by the communication unit 24. On the other hand, when it is determined that the received imaging order information is not stored in the imaging order information storage unit 261, or when it is determined that the interrupt mode is set, the radiographic image recorded in the attached cassette Information is read to generate image data, and information indicating that it has been read without photographing order information is written in the header portion of the generated image data so as to be associated and stored in the HDD 28. The image data stored in the HDD 28 is transmitted to the control device 3 in response to pressing of the transmission button or after a predetermined time has elapsed since the storage.

  Therefore, the imaging device information is input by the control device 3 provided in the examination room and transmitted to the radiographic image reading device. In the radiographic image reading device, the read image data is associated with the receiving order of the imaging order information. In the small-scale diagnosis system 1 to be transmitted to the radiographic image, when the imaging order information from the control device 3 is not received, the image data read from the radiographic cassette can be stored in the HDD 28. In addition, shooting and reading can be started quickly without waiting for input of shooting order information from the control device 3.

  Further, even when imaging order information is received from the control device 3, image data read from a radiographic cassette is controlled in association with the received imaging order information by pressing an interrupt button. Since the operation transmitted to the apparatus 3 can be switched to the operation stored in the HDD 28 without associating with the imaging order information, it is possible to promptly input the imaging order information from the control apparatus 3 and wait for the order in an emergency or the like. Shooting and reading can be started.

  When the image data is stored in the HDD 28, information indicating that the image data is read without the shooting order information is stored in association with each other, so that the image data is read without the shooting order information. It becomes possible to do.

  In addition, the description content in the said embodiment is a suitable example of the small-scale diagnosis system 1 which concerns on this invention, and is not limited to this.

  For example, in the above embodiment, the case where the HDD is applied to the storage unit has been described as an example. However, the present invention is not limited to this, and any storage device that can read and write image data may be used.

  In addition, the detailed configuration and detailed operation of each device constituting the small-scale diagnosis system 1 can be changed as appropriate without departing from the spirit of the present invention.
