Description

Technical Field

[0001] The present invention relates to an X-ray fluoroscopy apparatus for acquiring an image by irradiating a subject with radiation. Background Art

[0002] The X-ray fluoroscopy device is used for X-ray examination of the whole body including the digestive tract by taking and displaying fluoroscopic images or X-ray still images in real time. As described in Patent Document 1, the X-ray fluoroscopy device is configured to operate the device body (fluoroscopy table) through a remote control console and a close-up control console.

[0003] The main body of the imaging device is arranged in the inspection room, and the remote operation console is arranged in the operation room which is shielded from the inspection room by an X-ray shielding plate. The proximity operation console is arranged in the inspection room. Generally speaking, in order to avoid radiation, the operator uses the remote operation console in the operation room when taking X-ray still images, and uses the proximity operation console in the inspection room when taking fluoroscopic images with a lower X-ray irradiation dose than that of X-ray still images.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2008-167782

[0005] Since the proximity console is connected to the X-ray imaging apparatus main body via a cable on the floor in the examination room, the operator's feet may be caught by the cable in the examination room.

[0006] Furthermore, since the remote console has high functions but is expensive, the functions of the local console are limited and a cheap console is used, thereby suppressing the price of the entire device. Summary of the invention

[0007] An object of the present invention is to configure an operating console to transmit wireless signals so that the operating console can be carried to a desired location for use.

[0008] In order to achieve the above-mentioned purpose, the X-ray fluoroscopic imaging device of the present invention has an imaging device body, a portable operating table, and a charging table for supplying power to the operating table. The imaging device body includes: a workbench; an X-ray irradiation device that irradiates an object mounted on the workbench with X-rays; an X-ray detector that detects X-rays that pass through the object; and an X-ray control unit that controls the X-ray irradiation device. The operating table includes: an operating unit that receives an operation from an operator; an operating table transmitter that transmits the operation received by the operating unit through a wireless signal; and an operating table control unit that controls the transmitter. The charging table includes: a mounting surface that mounts the operating table; a mounting detection unit that detects whether the operating table is mounted on the mounting surface; a power transmission unit that charges the operating table mounted on the mounting surface; a charging table receiver that receives a wireless signal sent from the operating table transmitter; and a charging table control unit that outputs the reception signal output by the charging table receiver to the X-ray control unit via a connected cable. The imaging device body includes a main body receiver that receives a wireless signal sent from the operating table transmitter and outputs the reception signal to the X-ray control unit. When the loading detection unit detects that the operating table is loaded on the loading surface of the charging table, the X-ray control unit uses the receiving signal received from the charging table control unit to control the X-ray irradiation device. When the loading detection unit does not detect that the operating table is loaded on the loading surface of the charging table, the X-ray control unit uses the receiving signal received from the main body receiving unit to control the X-ray irradiation device.

[0009] Effects of the Invention

[0010] According to the present invention, since the operation console transmits a wireless signal, the operation console can be carried to a desired location for use, thereby improving convenience. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] Hereinafter, embodiments of the present invention will be described using the drawings.

[0028] <<Implementation Method 1>>

[0029] The X-ray fluoroscopy apparatus 1 according to the first embodiment will be described with reference to the drawings. Figure 1 to Figure 4 This is a block diagram showing the overall configuration of the X-ray fluoroscopy apparatus 1 according to the first embodiment. Figure 5 2 is a block diagram showing the structure of an operation platform and a fixed charging platform 200 . Figure 6 2 is a block diagram showing the structure of the proximity charging stand 300 . Figure 7 and Figure 8 It is a block diagram and a perspective view showing the structure of the workbench-side charging station 400.

[0030] The X-ray fluoroscopic imaging device 1 includes an imaging device body 500, a portable operating table 100, a fixed charging table 200 for supplying power to the operating table 100, a proximity charging table 300, and a table-side charging table 400. The imaging device body 500, the proximity charging table 300, and the table-side charging table 400 are arranged in the inspection room 2, and the fixed charging table 200 is arranged in the operation room 3 shielded from the inspection room 2 by the X-ray shielding plate 4. The fixed charging table 200 is fixed in the operation room 3. The table-side charging table 400 is fixed to the table 510 of the imaging device body 500. The proximity charging table 300 can be moved in the inspection room 2.

[0031] The imaging device body 500 includes: a workbench 510; an X-ray irradiation device 520 for irradiating an object 10 mounted on the workbench 510 with X-rays; an X-ray detector 530 for detecting X-rays transmitted through the object 10; and an X-ray control unit 570 for controlling the X-ray irradiation device 520. Here, the X-ray irradiation device 520 and the X-ray detector are disposed opposite to each other via a C-arm 540. The C-arm 540 is supported by a drive mechanism 550 so as to be rotatable.

[0032] Furthermore, the photographing device body 500 includes a bracket 560 for supporting the driving mechanism 550. A main body receiving antenna 580 is provided on the upper portion of the bracket 560 as a receiving unit for receiving wireless signals from the console 100. The main body receiving antenna 580 has not only a receiving function but also a transmitting function so as to establish a wireless communication protocol with the transmitting antenna 102 of the console 100.

[0033] An X-ray control unit 570 is disposed inside the bracket 560. The fixed charging station 200 is connected to the X-ray control unit 570 via a cable 600. The X-ray control unit 570 receives signals from the main body receiving antenna 580 and signals from the fixed charging station 200, and controls the X-ray irradiation device 520, the X-ray detector 530, the driving mechanism 550, and the like.

[0034] Furthermore, an image generating unit (not shown) is disposed in the support 560 , and processes the detection signal of the X-ray detector 530 under the control of the X-ray control unit 570 to generate a fluoroscopic image and a still image.

[0035] like Figure 5 to Figure 7 As shown, the operation station 100 includes an operation unit 101 for receiving an operation from an operator and an operation station transmitting unit, i.e., a transmitting antenna 102, for transmitting the operation received by the operation unit 101 via a wireless signal. The transmitting antenna 102 has not only a transmitting function but also a receiving function so as to establish a wireless communication protocol between the main body receiving antenna 580 and the charging station receiving antenna 202 described later.

[0036] The console 100 includes a power receiving coil 105, a battery 106, a mounting position detection unit 107, an acceleration sensor 104, and a console control unit 103. The power receiving coil 105 receives power supplied in a non-contact manner and stores the power in the battery 106.

[0037] The mounting position detection unit 107 at least detects whether the workbench 100 is mounted on the workbench side charging table 400. In this embodiment, the mounting position detection unit 107 is configured to detect whether the workbench 100 is mounted on any one of the fixed charging table 200, the proximity charging table 300, and the workbench side charging table 400.

[0038] The acceleration sensor 104 functions as a movement sensor that detects whether the operation console 100 is moving.

[0039] On the other hand, Figure 5 As shown, the fixed charging station 200 includes a mounting surface 201 on which the operation station 100 is mounted, a mounting detection unit 204 , a power transmission coil 205 , a charging station receiving antenna 202 , and a charging station control unit 203 .

[0040] The placement detection unit 204 detects whether the operation console 100 is placed on the placement surface 201. For example, the placement detection unit 204 can be formed of a micro switch.

[0041] The power transmission coil 205 transmits electromagnetic waves to a power receiving unit of the console 100 mounted on the mounting surface, thereby supplying power to the console 100 in a non-contact manner. Although not shown, a power cable is connected to the power transmission coil 205, so that power is supplied.

[0042] The charging station receiving antenna 202 receives the wireless signal transmitted from the transmitting antenna 102 of the operation station 100. The charging station receiving antenna 202 has not only a receiving function but also a transmitting function so as to establish a wireless communication protocol with the transmitting antenna 102 of the operation station 100.

[0043] One end of the cable 600 is connected to the charging station control unit 203, and the other end of the cable 600 is connected to the X-ray control unit 570 of the imaging device body 500. The charging station control unit 203 outputs the output of the onboard detection unit 204 to the X-ray control unit 570 via the cable 600. In addition, the charging station control unit 203 outputs the reception signal received by the charging station receiving antenna 202 to the X-ray control unit 570 via the cable 600.

[0044] Therefore, the reception signal received by the charging station receiving antenna 202 of the fixed charging station 200 is input to the X-ray control unit 570 via the cable 600 , and the reception signal received by the main body receiving antenna 580 of the imaging device main body 500 is input to the X-ray control unit 570 .

[0045] When the loading detection unit 204 detects that the operating table 100 is loaded on the loading surface of the fixed charging table 200, the X-ray control unit 570 uses the receiving signal received from the charging table receiving antenna 202 to control the X-ray irradiation device 520. When the loading detection unit 204 does not detect that the operating table 100 is loaded on the loading surface of the fixed charging table 200, the X-ray control unit 570 uses the receiving signal received from the main body receiving unit to control the X-ray irradiation device 520.

[0046] like Figure 6 As shown, the proximity charging station 300 is provided with wheels 307 so as to be movable in the examination room 2 .

[0047] The proximity charging station 300 includes a proximity charging station mounting surface 301 on which the workstation 100 is mounted. The proximity charging station 300 includes a power transmission coil 305 for contactlessly charging the power reception coil 105 of the workstation 100 mounted on the proximity charging station mounting surface 301, a proximity charging station control unit 303, and a battery 306.

[0048] like Figure 7 and Figure 8 As shown, the workbench side charging stand 400 includes a mounting mechanism 410. The workbench side charging stand 400 is mounted on the side surface of the workbench 510 of the photographing device body 500 by the mounting mechanism 410.

[0049] The workbench charging station 400 includes a workbench mounting surface 401 on which the workbench 100 is mounted. A workbench power transmission coil 405 for charging the workbench 100 mounted on the workbench mounting surface 401, a control unit 403, and a battery 406 are arranged in the workbench charging station 400.

[0050] The mounting position detection unit 107 of the above-mentioned operating table 100 detects whether the operating table 100 is mounted on any one of the fixed charging table 200, the proximity charging table 300 and the workbench side charging table 400 by detecting the protrusions 211, 311, 411 set on the mounting surfaces 201, 301, 401 of the fixed charging table 200, the proximity charging table 300 and the workbench side charging table 400 respectively.

[0051] Specifically, the mounting position detection unit 107 of the operation table 100 includes a recessed portion provided on the lower surface 110 of the operation table 100 in a manner engaged with the protrusions 211, 311, 411, and a light sensor disposed in the recessed portion. When the operation table 100 is mounted on the mounting surfaces 201, 301, 401 of the fixed charging table 200, the proximity charging table 300, and the workbench side charging table 400, the protrusions 211, 311, 411 of the mounting surfaces 201, 301, 401 are inserted into the recessed portion of the mounting position detection unit 107 on the lower surface of the operation table 100 and detected by the light sensor.

[0052] At this time, if Fig. 9 As shown in (a), the mounting position detection unit 107 is arranged at four locations on the lower surface of the operation table 100. In contrast, the convex portions 211 of the mounting surface 201 of the fixed charging table 200 are arranged at two locations, the convex portions 211 of the mounting surface 301 close to the charging table 300 are arranged at three locations, and the convex portions 411 of the mounting surface 401 of the workbench side charging table 400 are arranged at four locations (refer to Fig. 9 (b)~(d)).

[0053] Therefore, the operation table control unit 103 can detect whether the operation table 100 is mounted on the fixed charging table 200, the proximity charging table 300, or the workbench side charging table 400 by identifying how many of the four mounting position detection units 107 of the operation table 100 have detected the insertion of the protrusion. Specifically, when two of the four mounting position detection units 107 detect the insertion of the protrusion, as Figure 1 As shown, the operation table control unit 103 can detect that the operation table 100 is mounted on the fixed charging table 200. When three of the four mounting position detection units 107 detect the insertion of the protrusion, as shown in FIG. Figure 2 As shown, the operation table 100 is mounted on the proximity charging table 300. When four of the four mounting position detection units 107 detect the insertion of the protrusion, as shown in FIG. Figure 3 As shown, the operating table 100 is mounted on a workbench-side charging table 400 .

[0054] When the operation station control unit 103 detects that the mounting position detection unit 107 is mounted on the fixed charging station 200 and the proximity charging station 300 , the operation station control unit 103 transmits a wireless signal from the transmission antenna 102 for all operations accepted by the operation unit 101 .

[0055] When the console 100 is mounted on the workbench side charging stand 400, the console control unit 103 prohibits (interlocks) the transmission of wireless signals from the transmission antenna 102 for predetermined types of operations among the operations accepted by the operation unit 101. The predetermined types of operations include, for example, the photography of X-ray still images. Since the workbench side charging stand 400 is mounted on the workbench 510 of the imaging device body 500, the operator who operates the console 100 on the workbench side charging stand 400 stands close to the workbench 510. In this state, if the photography of X-ray still images is performed, the dose of X-rays when taking the X-ray still images is large, so the operator is irradiated. When the console 100 is mounted on the workbench side charging stand 400, the console control unit 103 prohibits the transmission of wireless signals even if the operation of photographing X-ray still images is performed, thereby not performing photography. In addition, since the dose is small, photography of X-ray fluoroscopic images can be performed.

[0056] Furthermore, a motion sensor is disposed on the operation table 100 to detect whether the operation table 100 is moving.

[0057] Based on the detection results of the four mounting position detection units 107 of the operation table 100, when it is detected that the operation table 100 is not mounted on any of the fixed charging table 200, the proximity charging table 300, and the workbench side charging table 400, the operation table control unit 103 receives the output of the acceleration sensor 104. When the acceleration sensor 104 detects acceleration in a certain direction, it is determined that the operation table 100 is being carried (moved) by the operator, and the transmission of wireless signals from the transmission antenna 102 is prohibited for all operations accepted by the operation unit 101.

[0058] On the other hand, based on the detection results of the four mounting position detection units 107 of the operating table 100, when the operating table 100 is not mounted on any of the fixed charging table 200, the proximity charging table 300, and the workbench side charging table 400 and the acceleration sensor 104 does not detect acceleration, the operating table control unit 103 determines that the operating table 100 is not mounted on any of the fixed charging table 200, the proximity charging table 300, and the workbench side charging table 400. Figure 4 As shown, it is placed at a position other than the charging unit in the examination room 2. In this case, the console control unit 103 permits transmission of wireless signals for all operations, and permits all operations.

[0059] Below, use Fig.10 The operation of the X-ray control unit 570 is described below.

[0060] In addition, the functions of the X-ray control unit 570 can be realized by software. In this case, the X-ray control unit 570 is composed of a computer equipped with a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), a memory, etc., and the CPU reads and executes the program stored in the memory, thereby realizing these functions. In addition, part or all of the X-ray control unit 570 can also be composed of hardware. For example, a custom IC such as an ASIC (Application Specific Integrated Circuit) or a programmable IC such as an FPGA (Field-Programmable Gate Array) can be used to design circuits to realize the functions of each unit.

[0061] (Step S1001)

[0062] The X-ray control unit 570 receives the output of the mounting detection unit 204 and determines whether the operation table 100 is mounted on the mounting surface 201 of the fixed charging table 200. When the operation table 100 is mounted on the fixed charging table 200, the process proceeds to step S1002. When it is not detected that the operation table 100 is mounted on the fixed charging table 200, the process proceeds to step S1003.

[0063] (Step S1002)

[0064] The X-ray control unit 570 controls the X-ray irradiation device 520 and the like using a reception signal received from the charging station receiving antenna 202 via the cable 600 , and performs operations such as imaging.

[0065] (Step S1003)

[0066] When the operation table 100 is not detected to be mounted on the mounting surface of the fixed charging table 200 , the X-ray control unit 570 controls the X-ray irradiation device 520 and the like using the reception signal received from the main body receiving antenna 580 to perform operations such as imaging.

[0067] In this way, when the operating table 100 is configured in the operating room 3 where the fixed charging table 200 is located, the X-ray control unit 570 selects the receiving signal received via the cable 600. When the operating table 100 is not mounted on the fixed charging table 200, it can be determined that it is configured in the inspection room 2, and therefore the receiving signal received from the main body receiving antenna is selected and controlled.

[0068] Thus, even when both the charging station receiving antenna 202 in the operating room 3 and the main body receiving antenna 580 in the examination room 2 receive the wireless signal transmitted from the operating table 100, the X-ray control unit 570 can select the received signal and perform control. Therefore, it is possible to prevent a malfunction caused by double reception of a wireless signal indicating an operation, and to select the earliest received signal, thereby preventing a time delay in response to the operation.

[0069] Next, use Fig.11 , the operation of the console control unit 103 is explained.

[0070] In addition, similarly to the X-ray control unit 570 , the console control unit 103 may realize its functions by software or by hardware.

[0071] (Step S1101)

[0072] The console control unit 103 determines the position at which the console 100 is placed based on the outputs of the four placement position detection units 107 .

[0073] (Step S1102)

[0074] When two of the four mounting position detection units 107 detect the convex portion (two are on (ON)), the console control unit 103 proceeds to step S1106, and when not two are on, proceeds to step S1103.

[0075] (Step S1106)

[0076] The console control unit 103 determines that the console 100 is Figure 1 As shown in FIG. 1 , the operation panel 101 is located on the fixed charging stand 200 and operates as a remote operation panel. That is, the operation panel control unit 103 transmits wireless signals for all operations received by the operation unit 101 from the transmission antenna 102 .

[0077] (Step S1103)

[0078] In step S1103, when three of the four mounting position detection units 107 detect the convex portion (three are on), the control console control unit 103 proceeds to step S1107, and when not three are on, the control console control unit 103 proceeds to step S1104.

[0079] (Step S1107)

[0080] The console control unit 103 determines that the console 100 is Figure 2As shown in FIG. 1 , the operation panel 101 is located on the proximity charging stand 300 and operates as a proximity operation panel. That is, the operation panel control unit 103 transmits wireless signals of all operations received by the operation unit 101 from the transmission antenna 102. At this time, the operation panel control unit 103 ignores the output of the acceleration sensor 104.

[0081] (Step S1104)

[0082] In step S1104 , the console control unit 103 proceeds to step S1108 when all four mounting position detection units 107 detect the convex portion (four are turned on), and proceeds to step S1105 when none of the four are turned on.

[0083] (Step S1108)

[0084] The console control unit 103 determines that the console 100 is Figure 3 As shown in FIG. 1 , the console control unit 103 is located on the workbench side charging table 400 and operates as a workbench side console. That is, for a predetermined type of operation (e.g., X-ray still image photography) among the operations accepted by the operation unit 101, the console control unit 103 prohibits (interlocks) the transmission of wireless signals from the transmission antenna 102. For other operations, transmission is performed from the transmission antenna 102.

[0085] Thus, a predetermined type of operation is prohibited according to the arrangement position of the operation table 100 , thereby ensuring the safety of the operator or the subject 10 .

[0086] (Step S1105)

[0087] The operation station control unit 103 determines that the operation station 100 is not mounted on the charging station 200 , 300 , or 400 , and the process proceeds to step S1109 .

[0088] (Step S1109)

[0089] The console control unit 103 receives the output of the acceleration sensor 104 , and proceeds to step S1110 when the output of the acceleration sensor 104 is less than a threshold value, and proceeds to step S1111 when the output of the acceleration sensor 104 is greater than the threshold value.

[0090] (Step S1110)

[0091] In step S1110, the console control unit 103 determines that the console 100 is Figure 4 As shown, the control station 103 is placed at a position other than the charging stations 300 and 400 in the examination room 2. The control station control unit 103 transmits wireless signals for all operations from the transmission antenna 102.

[0092] (Step S1111)

[0093] On the other hand, in step S1111, when the acceleration sensor 104 detects acceleration in a certain direction, the console control unit 103 determines that the console 100 is being carried (moving) by the operator, and prohibits (interlocks) the transmission of wireless signals from the transmitting antenna 102 for all operations accepted by the operating unit 101.

[0094] Then, the console control unit 103 displays an error message on the connected display unit.

[0095] As described above, the X-ray fluoroscopy device 1 of this embodiment can configure the operating table 100 that sends wireless signals in the operating room 3 and use it as a fixed operating table, and can freely move it from the operating room 3 to the inspection room 2 and use it as a close proximity operating table, and can also be configured next to the workbench 510 for use.

[0096] At this time, the X-ray control unit 570 selects and uses the outputs of the main body receiving antenna 580 and the charging station receiving antenna 202 of the fixed charging station 200, so that no malfunction will occur even if the wireless operating table 100 is moved.

[0097] In this way, since one wireless console 100 can be freely moved and used, the convenience of the operator can be improved, and since only one console 100 is required, the price of the entire X-ray fluoroscopy apparatus 1 can be suppressed.

[0098] Furthermore, when the wireless console 100 is placed on the workbench side in the inspection room 2 for operation, the X-ray fluoroscopy apparatus 1 of this embodiment can ensure safety such as preventing the operator from being exposed to radiation by prohibiting (interlocking) specific types of operations such as X-ray still image photography.

[0099] Furthermore, the proximity charging station 300 has a built-in battery 306, and during the X-ray inspection, no cable is connected to the proximity charging station 300. Therefore, there is also an advantage that the inspection can be easily performed while the proximity charging station 300 is moved.

[0100] In addition, in the above-mentioned embodiment, the case is described in which the transmitting antenna 102 of the operating station 100 sends information about the operation received by the operating station 100 from the user to the charging station receiving antenna 202 of the fixed charging station 200 and the main body receiving antenna 580 of the main body 500, but it can also be configured to send and / or receive information other than operation information.

[0101] For example, the configuration may be such that information on photographic conditions such as tube current or tube voltage and captured images are wirelessly transmitted from the charging station receiving antenna 202 of the fixed charging station 200 or the main body receiving antenna 580 of the main body 500 to the operating console 100, and the transmitting antenna 102 of the operating console 100 receives the information and displays the photographic conditions such as tube current or tube voltage and captured images on a display provided on the operating console 100.

[0102] Implementation Method 2

[0103] use Fig.12 , Fig.13 , Fig.14 , an X-ray fluoroscopy apparatus 1 according to a second embodiment will be described.

[0104] In the X-ray fluoroscopy apparatus 1 of the first embodiment, since the battery 306 is built in the proximity charging stand 300, it is easy to perform inspection while moving close to the charging stand 300. In the second embodiment, a backup battery 310 is further mounted in the battery 306 close to the charging stand 300 to cope with X-ray inspection for a longer period of time.

[0105] The method of charging the control console 100 from the backup battery 310 can be performed in a non-contact manner via the power transmission coil 305 described in Embodiment 1, but is not limited to non-contact charging. Fig.12 As shown, a detachable cable 308 may also be connected from the proximity charging station 300 to the operating station 100 to transmit power from the backup battery 310 to the battery 106 of the operating station 100 .

[0106] And, if Fig.13 As shown, a connector 309 may be provided in the proximity charging station control unit 303. In this case, by connecting the connector 309 to the connector 602 at the end of the cable 601 of the imaging device body 500, the battery 306 can be charged via the cable 601 and the proximity charging station control unit 303 when performing a long X-ray inspection. In addition, the cable 601 is connected to an external power source via the imaging device body 500.

[0107] And, if Fig.14 As shown, a connector 407 may be provided in the control unit 403 of the workbench side charging station 400. Thus, when a long-term X-ray inspection is performed, the battery 406 of the workbench side charging station 400 can be charged via the cable 601 and the control unit 403 by connecting the connector 407 to the connector 602 at the end of the cable 601 of the imaging device body 500.
