Description

[Technical field]

[0001] The present invention relates to an image display system that displays images bidirectionally inside and outside a radiation controlled area. [Background technology]

[0002] Conventionally, there has been a system that displays images bidirectionally inside and outside a radiation controlled area (see Patent Document 1). In Patent Document 1, an entrance / exit management device installed in a radiation controlled area is equipped with a CCD camera that captures images of workers there and a microphone that receives the voices of the workers. Also, a checkpoint monitoring device in a central monitoring station is equipped with a display unit that displays images from the CCD camera, a speaker that emits voices from the microphone, a CCD camera that captures images of monitors, and a microphone that receives the monitors' voices. By switching between the speaker and display unit, in conjunction with the CCD camera and microphone, workers and monitors can communicate while viewing each other's images.

[0003] [Patent Document 1] JP 2001-211445 A Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention has an object to provide an image display system that allows workers inside and outside a radiation controlled area to easily check the status of each other's area while reducing the effects of radiation on equipment. [Means for solving the problem]

[0005] The image display system of the first invention (for example, an image display system 10 described later) is an image display system that displays images bidirectionally inside and outside a radiation controlled area (for example, a radiological examination room 2 described later), and includes a first imaging device (for example, a first camera 11 described later) having radiation resistance that is provided in the radiation controlled area, a second imaging device (for example, a second camera 13 described later) that is provided outside the radiation controlled area (for example, an operation room 3 described later), and a first display device (for example, a second display device 14 described later) having radiation resistance that is provided in the radiation controlled area and connected to the first imaging device and the second imaging device via a radiation resistant signal cable (for example, a radiation resistant signal cable 30 described later). and a second display device (e.g., a second monitor 14 described later) that is provided outside the radiation controlled area and connected to the first imaging device via a radiation-resistant signal cable, and that is also connected to the second imaging device via a signal cable (e.g., a signal cable 31 described later), wherein the first imaging device photographs the radiation controlled area and outputs the photographed image, the second imaging device photographs the area outside the radiation controlled area and outputs the photographed image, and the first display device and the second display device are capable of selectively displaying an image photographed by the first imaging device or an image photographed by the second imaging device.

[0006] Examples of the first imaging device having radiation resistance include the CID8825AX1, a PTZ radiation-resistant CID camera manufactured by Thermo Scientific, the CID8725D, a radiation-resistant CID monochrome camera manufactured by Thermo Scientific, and the CID8825D, a radiation-resistant CID color camera manufactured by Thermo Scientific. According to this invention, a first imaging device and a first display device are installed in a radiation controlled area, and a second imaging device and a second display device are installed outside the radiation controlled area, and these are connected by a radiation-resistant signal cable or a signal cable. This allows a worker in a radiation controlled area to check the situation outside the radiation controlled area through the image displayed on the first display device without leaving the radiation controlled area. Similarly, a worker outside the radiation controlled area can check the situation inside the radiation controlled area through the image displayed on the second display device without entering the radiation controlled area. In this way, workers inside and outside the radiation controlled area can easily check the situation of each other's area without entering each other's area. This minimizes the risk of radiation exposure to workers and improves safety. In addition, the first imaging device and the first display device in the radiation controlled area are made radiation-resistant and are connected by a radiation-resistant signal cable, so that the effects of radiation on the devices can be reduced.

[0007] Also, for example, the radiation controlled area is a radiation examination room, and the outside of the radiation controlled area is an operation room, and the radiation equipment placed in the radiation examination room is operated by a control panel in the operation room. In this case, conventionally, lead glass is provided between the radiation examination room and the operation room, and the situation in the radiation examination room is grasped from the operation room through this lead glass. However, according to the present invention, since the situation in the radiation examination room can be grasped through the second monitor, it is no longer necessary to provide lead glass, and the environmental burden due to the use of lead can be reduced. In addition, it is no longer necessary to layout the radiation examination room and the operation room adjacent to each other, and the degree of freedom of layout is increased. In addition, the degree of freedom of layout is increased, and it is possible to rationalize the design, and it is possible to reduce the usage area and design costs compared to the conventional method. By displaying characters and pictures on the first display device, it is possible to convey a message to a patient with hearing impairment. In addition, if the first imaging device is set to track the movement of a person, it is possible to track the patient and monitor the patient more closely than before. Furthermore, by storing images from the first photographing device in a storage device at predetermined time intervals, when an incident occurs to a patient, the incident can be analyzed based on the stored images, making it possible to provide the patient with medical care that is strong in emergency situations.

[0008] The image display system of the second invention is characterized in that the first display device comprises an image display unit (e.g., image display unit 20 described below) that displays an image, and protection means (e.g., protective cover 21 described below) that protects the image display unit from radiation, and the protection means is lead glass or a radiation-resistant plastic plate that covers the display surface of the image display unit, or radiation-resistant grease or radiation-resistant epoxy resin paint applied to the image display unit.

[0009] Here, the lead glass is, for example, a radiation shielding glass. Examples of radiation-resistant plastic plates include PEEK (polyether ether ketone), PI (polyimide), PEI (polyetherimide), PPSU (polyphenylsulfone), PSU (polysulfone), and PES (polyester), all manufactured by Ensinger. Examples of radiation-resistant grease include polyphenyl ether-type greases MORESCO HYLAD RP-42, MORESCO HYLAD RP-42R, and MORESCO HYLAD RP-42S manufactured by MORESCO Corporation. Examples of radiation-resistant epoxy resin paints include Eponix #3100AP manufactured by Dai Nippon Toryo Co., Ltd. and Epomarine RXM Primer manufactured by Kansai Paint Co., Ltd.

[0010] According to this invention, the first display device to be installed in a radiation controlled area includes an image display unit and a protection means for protecting the image display unit from radiation. Furthermore, the protection means is lead glass or a radiation-resistant plastic plate covering the display surface of the image display unit, or a radiation-resistant grease or a radiation-resistant epoxy resin paint applied to the image display unit. This improves the radiation resistance of the first display device, and allows the first display device to display images even in a radiation controlled area.

[0011] The image display system of a third invention is characterized in that the second display device is installed outside the radiation controlled area. According to this invention, an image captured by a first imaging device in a radiation controlled area is displayed on a second display device installed outside the radiation controlled area via a radiation-resistant signal cable. This allows workers outside the radiation controlled area to check the situation of the radiation controlled area through the second display device without entering the radiation controlled area, minimizing the risk of radiation exposure. Effect of the Invention

[0012] According to the present invention, it is possible to provide an image display system that allows workers inside and outside a radiation controlled area to easily check the status of each other's area while reducing the effect of radiation on equipment. [Brief description of the drawings]

[Diagram 2] FIG. 1 is a diagram showing a configuration of an image display system according to a first embodiment. [Diagram 3] FIG. 11 is a schematic plan view of a radiological diagnostic system to which an image display system according to a second embodiment of the present invention is applied. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description of the embodiments, the same components are denoted by the same reference numerals, and the description thereof will be omitted or simplified. [First embodiment] Fig. 1 is a schematic plan view of a radiological diagnosis system 1 to which an image display system 10 according to a first embodiment of the present invention is applied. Fig. 2 is a diagram showing the configuration of the image display system 10. The radiological diagnostic system 1 comprises a radiological diagnostic room 2, which is a radiation controlled area, and an operation room 3, which is outside the radiation controlled area and is located adjacent to the radiological diagnostic room 2. The radiological diagnostic room 2 is a room in which radiological equipment is installed to treat and diagnose patients, and the operation room 3 is a room in which a control panel for operating the radiological equipment is installed. The image display system 10 is a system that displays images bidirectionally between the radiology examination room 2 and the operation room 3. This image display system 10 includes a first camera 11 as a first imaging device and a first monitor 12 as a first display device provided in the radiology examination room 2, and a second camera 13 as a second imaging device and a second monitor 14 as a second display device provided in the operation room 3.

[0015] The first camera 11 captures an image of the inside of the radiology examination room 2 and outputs the captured image. The second camera 13 photographs the inside of the operation room 3 and outputs the photographed image. The first monitor 12 is connected to the first camera 11 and the second camera 13 via a radiation-resistant signal cable 30. The first monitor 12 is capable of selectively displaying an image captured by the first camera 11 or an image captured by the second camera 13.

[0016] The second monitor 14 is connected to the first camera 11 via a radiation-resistant signal cable 30, and is connected to the second camera 13 via a non-radiation-resistant signal cable 31. The second monitor 14 is capable of selectively displaying an image captured by the first camera 11 or an image captured by the second camera 13. In this embodiment, only one first camera 11 is provided in the radiology examination room 2, but this is not limiting, and multiple first cameras 11 may be provided in the radiology examination room 2, and these multiple first cameras 11 may be connected to the first monitor 12 and the second monitor 14, so that an image selected from the multiple first cameras 11 may be displayed on the first monitor 12 and the second monitor 14. In this way, the situation inside the radiology examination room 2 can be grasped in detail.

[0017] The radiology consultation room 2 is a space surrounded by walls 40 made of reinforced concrete. The first monitor 12 includes an image display unit 20 that displays an image, and a protective cover 21 made of lead glass or a radiation-resistant plastic plate as a protective means for protecting the image display unit 20 from radiation. That is, the image display unit 20 is attached to the wall surface of the wall 40 of the radiology examination room 2, and the surface of this image display unit 20 is covered with the protective cover 21.

[0018] According to this embodiment, the following effects are obtained. (1) A first camera 11 and a first monitor 12 were installed in the radiology examination room 2, and a second camera 13 and a second monitor 14 were installed in the operation room 3, and these were connected by a radiation-resistant signal cable 30 or a signal cable 31. This allows a worker in the radiology examination room 2 to check the situation in the operation room 3 through the image displayed on the first monitor 12 without leaving the radiology examination room 2. Similarly, a worker in the operation room 3 can check the situation in the radiology examination room 2 through the image displayed on the second monitor 14 without entering the radiology examination room 2. In this way, workers in the radiology examination room 2, which is a radiation controlled area, and the operation room 3, which is outside the radiation controlled area, can easily check the situation in each other's area without entering each other's area. This minimizes the risk of radiation exposure for workers and improves safety. In addition, messages can be conveyed to hearing-impaired patients by displaying characters and figures on the first monitor 12 and the second monitor 14. Furthermore, the first camera 11 and the first monitor 12 in the radiology examination room 2 are made radiation-resistant and are connected by a radiation-resistant signal cable 30, so that the effects of radiation on the equipment can be reduced.

[0019] (2) The first camera 11 installed in the radiology examination room 2 includes an image display unit 20 and a protective cover 21 that protects the image display unit 20 from radiation. Furthermore, the protective cover 21 is made of lead glass or a radiation-resistant plastic plate that covers the display surface of the image display unit 20. This improves the radiation resistance of the first monitor 12, and allows images to be displayed on the first monitor 12 even in the radiology examination room 2.

[0020] (3) The image captured by the first camera 11 in the radiology examination room 2 is displayed on the second monitor 14 installed in the operation room 3 via a radiation-resistant signal cable 30. This allows an operator in the operation room 3 outside the radiology examination room 2 to check the situation in the radiology examination room 2 through the second monitor 14 without entering the radiology examination room 2, thereby minimizing the risk of radiation exposure.

[0021] Second Embodiment FIG. 3 is a schematic plan view of a radiological diagnosis system 1A to which an image display system 10 according to the second embodiment of the present invention is applied. This embodiment differs from the first embodiment in that one operation room 3 is provided for a plurality of radiology rooms 2. That is, a plurality of radiology examination rooms 2 (here, three) are provided adjacent to one operation room 3, and the radiological equipment in each radiology examination room 2 can be operated by a control panel in the operation room 3. An image display system 10 is provided between each radiology examination room 2 and the operation room 3. That is, three sets of image display systems 10 are provided in the radiology examination system 1A. According to this embodiment, the same effects as those (1) to (3) described above are obtained.

[0022] The present invention is not limited to the above-described embodiment, and modifications and improvements within the scope of the present invention that can achieve the object of the present invention are included in the present invention. For example, in each of the above-described embodiments, the protective means is the protective cover 21 made of lead glass or a radiation-resistant plastic plate, but this is not limited thereto, and the protective means may be radiation-resistant grease or radiation-resistant epoxy resin paint applied to the image display unit 20.
