  FIG. 1 shows a first embodiment.

  The management system 11 is, for example, an X-ray image diagnostic apparatus 12 that is an X-ray detector as a medical apparatus installed in a hospital or the like, and a management service company that provides maintenance service for the X-ray image diagnostic apparatus 12 The X-ray diagnostic imaging apparatus 12 and the management apparatus 13 are connected to each other via a communication line 14 such as the Internet, a general public line such as a telephone line, and a dedicated line.

  The X-ray image diagnostic apparatus 12 receives X-rays that have passed through an examiner on an X-ray tube 22 that emits X-rays generated by an X-ray generator 21, for example, a bed 23, and converts the X-ray image into a visible light image And an X-ray image tube 24 as a medical device for conversion into a camera, and a camera 25 for capturing a visible light image obtained by the X-ray image tube 24.

  The X-ray image tube 24 incorporates a power supply unit 26 that controls the X-ray image tube 24. For example, RS-232C or the like for transmitting operation information such as voltage and current for operating the X-ray image tube 24 to the power supply unit 26 and receiving data relating to visual field control and sensitivity control of the X-ray image tube 24 is provided. A terminal 27 for a standard serial communication method is provided.

  The camera 25 includes an optical system and a TV camera, and includes a standard serial communication method terminal 28 such as RS-232C for transmitting photographing data.

  The power supply unit 26 and the camera 25 of the X-ray image tube 24 are connected to a terminal device 29 that is a computer via terminals 27 and 28. The terminal 29 is also connected to an X-ray generator 21 and a recording device 30 for recording and reading data on a recording medium such as a magnetic disk, an optical disk, and a flash memory. The terminal 29 controls the X-ray image diagnostic apparatus 12.

  The X-ray diagnostic imaging apparatus 12 transmits operation information obtained by the operation of the power supply unit 26, operation information obtained by the operation of the camera 25, and the like to the management apparatus 13 through the communication line 14, and from the management apparatus 13 to the communication line. 14 receives data related to visual field control and sensitivity control of the X-ray image tube 24 by the power supply unit 26 transmitted through 14, and the power supply unit 26 has a function of operating the X-ray image tube 24 based on the received data. Yes.

  In addition, the management device 13 has a server 41 as a communication unit that can communicate with the terminal 29 of the X-ray image diagnostic apparatus 12 through the communication line 14, and the server 41 communicates with the X-ray image diagnostic apparatus 12. A computer 42 which is a control device is connected.

  The computer 42 functions as a determination means 43 for determining the state of the X-ray image diagnostic apparatus 12 based on the operation information transmitted from the X-ray image diagnostic apparatus 12, and transmits the X-ray image diagnostic apparatus 12 to the X-ray image diagnostic apparatus 12. It has storage means for storing data relating to visual field control and sensitivity control of the X-ray image tube 24.

  Next, the operation of the management system 11 will be described.

  In the X-ray image diagnostic apparatus 12, operation information and sensitivity information such as voltage and current for operating the X-ray image tube 24 by the power supply unit 26, operation information for operating the camera 25, and the like are sent to the terminal device 29. The information is stored and transmitted from the terminal 29 to the server 41 of the management apparatus 13 through the communication line 14.

  In the management apparatus 13, the operation information transmitted from the X-ray image diagnostic apparatus 12 through the server 41 is read by the computer 42, the state of the X-ray image diagnostic apparatus 12 is judged from the operation information, and appropriate information is obtained as necessary. The management apparatus 13 provides the X-ray image diagnosis apparatus 12 through the communication line 14, or a maintenance service company dispatches a service engineer or the like to the X-ray image diagnosis apparatus 12 to deal with it.

  With this management system 11, for example, on the management device 13 side, the life of the X-ray image tube 24 is predicted based on the operation information transmitted from the X-ray image diagnostic device 12, and the replacement time of the X-ray image tube 24 is determined. This can be proposed to the user of the X-ray diagnostic imaging apparatus 12. As a method of predicting the life of the X-ray image tube 24, a method of predicting from the current of the ion pump of the X-ray image tube 24 provided in the power supply unit 26, the aperture of the optical system of the camera 25, a CCD, or the like There are a method of predicting from the sensitivity of the image sensor, a method of predicting from the current value at the reference voltage of 0 V in the X-ray image tube 24, and the like. Therefore, on the management apparatus 13 side, the current of the ion pump, the current at the reference voltage of 0 V, and the operation information from the camera 25 are the operation information transmitted from the X-ray image diagnostic apparatus 12 from the power supply unit 26. The lifetime of the X-ray image tube 24 can be predicted based on the sensitivity of the image sensor.

  Further, abnormality diagnosis of the X-ray image tube 24 can be performed. As a method of diagnosing abnormality of the X-ray image tube 24, it is possible to determine a withstand voltage failure of the X-ray image tube 24 from currents flowing between the electrodes of the X-ray image tube 24. For example, normally, only a current of 1 μA or less flows between the anode and the electrode closest to the anode, but when a current of several tens of μA flows due to a foreign substance or the like attached to the electrode, the X-ray image tube 24 It can be determined that the withstand voltage is poor. Therefore, on the management device 13 side, the resistance of the X-ray image tube 24 is determined based on the current flowing between the electrodes of the X-ray image tube 24, which is operation information from the power supply unit 26 transmitted from the X-ray image diagnostic device 12. Voltage failure can be confirmed.

  Further, failure diagnosis of the X-ray image tube 24 and the camera 25 can be performed. As a method of diagnosing the failure of the X-ray image tube 24 and the camera 25, when no voltage is output from the power supply unit 26, it can be determined that the X-ray image tube 24 has failed, and the voltage is output from the power supply unit 26. If it is, it can be determined that the camera 25 is out of order. Therefore, on the management apparatus 13 side, whether the X-ray image tube 24 has failed or the camera 25 has failed based on the voltage that is the operation information from the power supply unit 26 transmitted from the X-ray image diagnostic apparatus 12. You can see if you are.

  If the life, abnormality, or failure of the X-ray image tube 24 is confirmed on the management device 13 side, the X-ray image diagnostic device has an X-ray image tube 24 for replacement by a service engineer of a maintenance service company. It is possible to go to 12 installation locations and immediately start the replacement work of the X-ray image tube 24, and the work time can be shortened compared to the conventional case.

  That is, in the conventional case, when an abnormality occurs in the image of the camera 25, first, only the camera 25 is operated without operating the X-ray image tube 24, and the current failure is the camera 25 side or the X-ray image tube 24 side. After confirming whether or not the camera 25 is removed from the X-ray image tube 24 and the output image of the X-ray image tube 24 is directly observed, an abnormality or failure of the X-ray image tube 24 is determined. It took a long time.

  Further, the field of view of the X-ray image tube 24 of the X-ray diagnostic imaging apparatus 12 can be easily changed to a size desired by the user. The visual field of the X-ray image tube 24 is achieved by a voltage applied to an electrode provided in the X-ray image tube 24. For example, when the field of view of the standard X-ray image tube 24 is 230 mm (9 type) / 150 mm (6 type) / 120 mm (4.5 type), the voltage applied to the electrode is changed to 230 mm (9 type). ) / 170 mm (7 type) / 130 mm (5 type).

  When the user of the X-ray image diagnostic apparatus 12 desires a change from the standard field of view of the X-ray image tube 24, the user requests the change from the maintenance service company or the like through the communication line 14, for example. The maintenance service company transmits voltage data corresponding to the field of view to be changed to the X-ray image diagnostic apparatus 12 through the communication line 14. The X-ray image diagnostic apparatus 12 receives and stores the data at the terminal 29 through the communication line 14 and supplies the data to the power supply unit 26. Based on the supplied data, the power supply unit 26 applies a necessary voltage to the electrodes of the X-ray image tube 24 to form the X-ray image tube 24 having a visual field desired by the user.

  When the field of view of the X-ray image tube 24 is changed, the service engineer responds to a business trip as compared to the case where a maintenance service company to a service engineer conventionally travels to the place where the X-ray image diagnostic apparatus 12 is installed. The need can be eliminated at all. The maintenance service company distributes data for items frequently requested by the user to a user who has a maintenance contract in advance, and the user fetches the data from the server 41 as necessary. As a result, the user side of the X-ray diagnostic imaging apparatus 12 can quickly satisfy the request without dispatching a person from the maintenance service company. On the other hand, for maintenance service companies, customers can provide necessary data quickly and the number of specialized engineers is minimized, leading to reduction of maintenance costs and maintenance service without degrading service quality. You can continue the contract.

  In addition, the management device 13 grasps the sensitivity of the X-ray image tube 24 from the operation information transmitted from the power supply unit 26 of the X-ray image tube 24, and if sensitivity decrease is recognized, the sensitivity data to be corrected is provided. The sensitivity of the X-ray image tube 24 can be corrected by sending it from the management device 13 to the X-ray image diagnostic device 12.

  In the case where it is difficult to maintain data confidentiality through the communication line 14, the same effect can be obtained by using a recording medium such as a magnetic disk, an optical disk, or a flash memory for data transfer.

  Therefore, in this management system 11, the operation information of the power supply unit 26 and the camera 25 of the X-ray image diagnostic apparatus 12 is transmitted to the management device 13 through the communication line 14, and the management device 13 uses the operation information of the power supply unit 26 and the camera 25 from Since the state of the X-ray image diagnostic apparatus 12 can be determined, the X-ray image diagnostic apparatus 12 does not require a sensor for detecting an abnormality or a diagnostic apparatus for diagnosis, and the X-ray image diagnostic apparatus 12 is complicated. In addition, the X-ray diagnostic imaging apparatus 12 can be managed without causing an increase in size and cost.

  Further, data relating to visual field control of the X-ray image tube 24 by the power supply unit 26 is transmitted from the management device 13 to the X-ray image diagnostic device 12 through the communication line 14, and the data received through the communication line 14 in the X-ray image diagnostic device 12. To the power supply unit 26, and the power supply unit 26 can control the field of view of the X-ray image tube 24 based on the data, and can easily cope with the user's request regarding the field of view of the X-ray image tube 24. Therefore, in response to the demand for changing the field of view of the X-ray image tube 24, the manufacturer prepares the X-ray image tube 24 with various field adjustments, or a professional engineer who adjusts the field of view of the X-ray image tube 24 Can reduce the cost of products and services.
