[0014] A radiographic device is a device that projects radiation (X-rays) onto the human body and reconstructs images of various organs within the body based on differences in the degree of absorption.

[0015] Among these radiation imaging devices, computed tomography (CT) can acquire images of cross-sections of the human body, and it is also possible to combine these images into a three-dimensional (3D) image.

[0016] A radiographic device irradiates radiation to acquire an image, and the radiation is directed toward the doctor who is the operator.

[0017] During the use of such radiation imaging devices, the operator is exposed to radiation emitted from the radiation generator, and if radiation therapy is performed for a long period, this may lead to the operator being exposed to radiation exceeding permissible limits.

[0018] Meanwhile, the operator displays the radiation image detected by the radiation detector on the display, and performs the procedure on the patient while viewing the display.

[0019] Previously, the procedure was performed with the display positioned so as not to obscure the patient's affected area; however, since the operator had to alternate between looking at the display and the patient's affected area while performing the procedure, there was a problem with reduced convenience and accuracy.

[0020]

[0021] To solve the aforementioned problems, the present invention aims to provide a radiation image display device capable of shielding radiation through a display made of a transparent shielding member while simultaneously viewing an image of the patient and performing a procedure.

[0022] However, the problems that the present invention aims to solve are not limited to those mentioned above, and other unmentioned problems will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0023]

[0024] To solve the aforementioned problem, the present invention provides a radiation image display device comprising a display that shields radiation incident toward the face of a practitioner and displays a radiation image, and a control unit that controls the output of the radiation image displayed on the display, wherein the display is made of a light-transmitting material.

[0025] The above display may be made of lead glass.

[0026] The radiation image display device of the present invention may further include a switch for the operator to turn the output of the radiation image on or off.

[0027] The radiation image display device of the present invention may further include a sensor for turning the output of the radiation image on or off by recognizing the motion of the operator.

[0028] The above control unit can turn on the output of the radiation image for a first set time and turn off the output of the radiation image for a second set time at a set period.

[0029] The above control unit can set the above setting cycle differently depending on the time required for the procedure.

[0030] The radiation image display device of the present invention may further include a projector that projects the radiation image onto the display.

[0031] The above display may include a lead glass plate and a transparent display coupled to the lead glass plate.

[0032] The radiation image display device of the present invention may further include a frame supporting the display and a movable member connected to the frame and configured to enable the display to move.

[0033] The radiation image display device of the present invention may further include a lower shielding member that shields radiation incident in the direction of the operator's torso.

[0034] The above display can be connected to the upper part of the lower shielding member.

[0035]

[0036] According to the present invention, radiation can be shielded and the patient's image can be viewed simultaneously through a display made of a transparent shielding member, thereby providing convenience to the operator during the procedure.

[0037] The effects obtainable from the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description below.

[0053]

[0054] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings.

[0055] FIG. 1 is a drawing illustrating an overall system for explaining a radiation image display device according to an embodiment of the present invention, FIG. 2 is a perspective view of a radiation imaging device according to an embodiment of the present invention, FIG. 3 is a drawing illustrating a radiation image display device according to a first embodiment of the present invention, FIG. 4 is a drawing illustrating a radiation image display device according to a second embodiment of the present invention, and FIG. 5 is a block diagram of a control device for a radiation image display device according to an embodiment of the present invention.

[0056] Referring to FIG. 1, the entire system of the present invention may be configured to include a radiation imaging device (100), a radiation image display device (200), and a radiation shielding device (300, 400).

[0057] A radiation imaging device (100) may be configured to include a main body (110), a C-arm (120), a radiation generator (123), and a radiation detector (125).

[0058] Although not shown in the drawing, a power supply and a control device may be provided inside the main body (110). Here, the power supply supplies power to the C-arm (120), the radiation generator (123), and the radiation detector (125). And, the control device can control the operation of the C-arm frame (120), the radiation generator (123), and the radiation detector (125) and process data.

[0059] The main body (110) is supported by a base (113) provided at the bottom and can be moved by a plurality of wheels mounted on the bottom of the base (113).

[0060] The C-arm (120) may be configured to include a C-arm frame (121), a radiation generator (123), and a radiation detector (125).

[0061] The C-arm frame (121) is formed in the shape of the letter C, with an opening facing forward and the opposite side of the opening being connected to the main body (110).

[0062] A radiation generator (123) is provided at one end (upper inner side) of the C-arm frame (121), and a radiation detector (125) may be provided at the other end (lower inner side) of the C-arm frame (121). That is, the radiation generator (123) and the radiation detector (125) are arranged facing each other at both ends of the C-arm frame (121).

[0063] Here, the radiation generator (123) and the radiation detector (125) may be installed to have mutually independent driving structures.

[0064] A patient table can be placed inside the C-arm frame (121).

[0065] A radiation generator (123) is a device for irradiating radiation (X-rays) toward a patient, and a radiation detector (125) is a device for obtaining a fluoroscopic image of the patient through radiation that has passed through the patient.

[0066] The radiation detector (125) converts radiation that has passed through the patient into visible light and generates a projected image of the patient. Additionally, the radiation detector (125) can convert the projected image of the patient into an electrical image signal and provide it to a radiation image display device (200).

[0067] The radiation image display device (200) can display a projected image of a patient detected by a radiation detector (123).

[0068] Accordingly, the operator (10) can perform the procedure on the patient while viewing the projected image of the patient displayed on the radiation image display device (200).

[0069] Specifically, referring to FIG. 3, the radiation image display device (200) may be configured to include a display (250), a frame (240) supporting the display (250), and a movable member (220) connected to the frame (240) and configured to allow the display (250) to move.

[0070] The movable member (220) may be configured to include a first shaft (221) configured to rotate horizontally with respect to a base (210) fixedly installed on the ceiling, and a second shaft (222) configured to rotate horizontally with respect to the first shaft (222). Here, a frame (240) may be rotatably connected to the end of the second shaft (222).

[0071] The display (250) can display a radiation image while shielding radiation incident toward the face of the operator (10).

[0072] Here, the display (250) may be made of a light-transmitting material, for example, lead glass.

[0073] Accordingly, the operator (10) has the advantage of being able to perform the procedure while simultaneously viewing the patient's image through the display (250).

[0074] Additionally, referring to FIG. 4, the radiation image display device (300) may be configured to include a lower shielding member (310), a display (320), and a transfer mounting member (330).

[0075] The lower shielding member (310) can shield radiation incident toward the torso of the operator (10). Here, a display (320) can be connected to the upper part of the lower shielding member (310).

[0076] Specifically, the lower shielding member (310) may be a plate-shaped structure formed to a predetermined height with a curved structure having a radius of curvature of a predetermined size on one side, configured such that a lead plate having a predetermined thickness is mounted inside.

[0077] The display (320) is configured to be mounted on the top of the lower shielding member (310) and may be made of a lead glass material having transparent properties. Additionally, the display (320) is structured to extend upward by a predetermined height from the top of the lower shielding member (310) and preferably has a curved surface identical to the curved structure of the lower shielding member (310).

[0078] The display (320) can display a radiation image while shielding radiation incident toward the face of the operator (10).

[0079] Here, the display (320) may be made of a light-transmitting material, for example, lead glass.

[0080] Accordingly, the operator (10) has the advantage of being able to perform the procedure while simultaneously viewing the patient's image through the display (320).

[0081] The display (320) may have arm insertion grooves (321) formed on both sides of the upper shielding member (320) with a structure that is recessed to a predetermined depth.

[0082] The transfer mounting member (330) is configured to be mounted on the lower end of the lower shielding member (310), and may include a wheel (331) that can change the position of the lower shielding member (310) according to the operator's intention, and may be a structure that can fix the position according to the user's intention.

[0083] Specifically, the main body (322) of the display (320) is configured to be mounted on the upper part of the lower shielding member (310), extends upward by a predetermined height, and may have a curved surface identical to the curved structure of the lower shielding member (310). Here, it is preferable that the main body (322) of the display (320) be composed of a glass material containing lead. More specifically, the main body (322) of the display (320) is composed of a glass material containing lead monoxide in its composition, and may be manufactured by melting a mixture having lead oxide (Pb3O4), silica sand (SiO2), and potassium carbonate (K2CO3) as main components.

[0084] It is preferable that the arm insertion groove (321) of the display (320) be formed in a structure that is recessed to a predetermined depth on both sides of the main body (322). Here, an arm contact cushioning member (323) is installed in a structure that wraps along the outer surface of the arm insertion groove (321), so that the arm of the operator (10) can be comfortably rested in the arm insertion groove (321). In addition, the corner portion of the arm insertion groove (321) can directly come into contact with the arm of the operator (10), thereby preventing safety accidents that could cause injury to the operator's (10) arm.

[0085] In this way, the present invention provides a display (320) including an arm insertion groove (321) and an arm contact cushioning member (323) to provide a passage through which the arm of a practitioner (10) can enter, thereby resolving the issue of the display (320) interfering with the movement trajectory of the arm during medical procedures, and thus maximizing the efficiency of medical procedures.

[0086] The transfer mounting member (330) may be configured to include a mounting frame (332), a connecting frame (333), and a wheel (331).

[0087] Specifically, the mounting frame (332) of the transfer mounting member (330) is configured to be mounted on each of the lower ends of both sides of the lower shielding member (310), and may be a frame structure that extends a predetermined length forward and backward.

[0088] Additionally, the connecting frame (333) may be a frame structure mounted to connect mounting frames (332) mounted on both lower sides of the lower shielding member (310) to each other and to support the lower side of the lower shielding member (310).

[0089] Additionally, the wheels (331) mounted on the front and rear of the mounting frame (332) may be structured such that the brake is engaged or disengaged by a pushing motion by the foot of the operator (10).

[0090] Referring to FIG. 5, a control device (200) of a radiation image display device according to an embodiment of the present invention may be configured to include a sensor (20), a switch (30), and a control unit (190).

[0091] The control unit (190) may be configured to include memory, but is not limited thereto, and memory may be provided separately.

[0092] The switch (30) is configured to turn the output of the radiation image on and off by the operator (10) and may be a foot switch operated by the operator's (10) foot, but is not limited thereto and may be mounted on the display (250, 320) or around it.

[0093] Additionally, the sensor (20) is a device for turning on and off the output of a radiation image by recognizing the motion of the operator (10) (e.g., hand movements, eye and mouth movements).

[0094] The control unit (190) can turn on and off the output of the radiation image displayed on the display (250, 320) based on the motion of the operator recognized by the sensor (20) or the on / off signal of the switch (30).

[0095] The control unit (190) can turn on the output of the radiation image for a first set time and turn off the output of the radiation image for a second set time at a set period.

[0096] Here, the control unit (190) can set the setting cycle differently depending on the time required for the procedure.

[0097] The above setting period, first and second setting times can be pre-set by the operator (10) and can be stored in the memory of the control unit (190).

[0098] For example, depending on the type, memory may include a hard disk type, magnetic media type, CD-ROM (compact disc read only memory), optical media type, magneto-optical media type, multimedia card micro type, flash memory type, ROM type (read only memory type), or RAM type (random access memory type), but is not limited thereto. Additionally, depending on its use / location, memory (154) may be a cache, buffer, main memory, or auxiliary memory, or a separately provided storage system, but is not limited thereto.

[0099] In this way, the radiation image display device according to the embodiment of the present invention can maximize visibility and minimize power consumption by displaying a radiation image on the display (250, 320) only when the output of the radiation image is required.

[0100] Although not shown in the drawings, the present invention may further include a projector that projects a radiation image onto a display (250, 320).

[0101] Here, the projector can receive a radiation image from a radiation detector (125) and project it onto a display (250, 320).

[0102] In contrast, the display (250, 320) may be configured to include a lead glass plate and a transparent display coupled to the lead glass plate.

[0103] To prevent damage caused by incident radiation, it is desirable to attach the transparent display to the back of a lead glass plate and position it so that it faces the operator's face.

[0104] Here, the transparent display can receive and display a radiation image from the radiation detector (125).

[0105] Accordingly, no separate projector is required, and the operator (10) can perform the procedure while viewing the radiation image through a transparent display.

[0106] The control unit (190), display (150), sensor (20), switch (30), and radiation detector (125) may each be equipped with a communication unit.

[0107] Here, the communication unit may perform wireless communication such as 5G (5th generation communication), LTE-A (long term evolution-advanced), LTE (long term evolution), Bluetooth, BLE (Bluetooth low energy), NFC (near field communication), and WiFi communication, or wired communication such as cable communication, but is not limited thereto.

[0108]
