Description

[Technical field]

[0001] The present invention relates to an X-ray fluoroscopic imaging apparatus that irradiates a subject with radiation and obtains an image. [Background technology]

[0002] X-ray fluoroscopy devices are used for X-ray examinations of the entire body, including the digestive tract, by capturing and displaying fluoroscopic images and still X-ray images in real time. As described in Patent Document 1, the X-ray fluoroscopy device is configured such that the imaging device main body (fluoroscopy table) is operated by a remote control console or a close-up control console.

[0003] The imaging device main body is placed in the examination room, and the remote control console is placed in an operation room separated from the examination room by an X-ray shield. The close-proximity operation console is placed in the examination room. In general, to avoid exposure, an operator uses the remote control console in the operation room when taking X-ray still images, and uses the close-proximity operation console in the examination room when taking fluoroscopic images, which have a lower X-ray exposure dose than X-ray still images.

[0004] [Patent Document 1] JP 2008-167782 A Summary of the Invention [Problem to be solved by the invention]

[0005] Because the proximity control console is connected to the X-ray device body by a cable on the floor inside the examination room, there are cases where the operator's foot is about to get caught in the cable inside the examination room.

[0006] Furthermore, since the remote control console is highly functional but expensive, the nearby control console may have limited functions and be an inexpensive control console, thereby reducing the price of the entire apparatus.

[0007] An object of the present invention is to provide a console that transmits radio signals and can be carried to a desired location for use. [Means for solving the problem]

[0008] In order to achieve the above object, the X-ray fluoroscopy apparatus of the present invention includes an imaging apparatus main body, a portable operation console, and a charging console for supplying power to the operation console. The imaging apparatus main body includes a table, an X-ray irradiation device for irradiating an object mounted on the table with X-rays, an X-ray detector for detecting X-rays transmitted through the object, and an X-ray control unit for controlling the X-ray irradiation device. The operation console includes an operation unit for receiving an operation from an operator, an operation console transmission unit for transmitting the operation received by the operation unit by wireless signal, and an operation console control unit for controlling the transmission unit. The charging console includes a mounting surface for mounting the operation console, a mounting detection unit for detecting whether the operation console is mounted on the mounting surface, a power transmission unit for charging the operation console mounted on the mounting surface, a charging console receiving unit for receiving a wireless signal transmitted from the operation console transmission unit, and a charging console control unit for outputting a reception signal output from the charging console reception unit to the X-ray control unit via a connected cable. The imaging apparatus main body includes a main body receiving unit for receiving a wireless signal transmitted from the operation console transmission unit and outputting the reception signal to the X-ray control unit. When the mounting detection unit detects that the operation console is mounted on the mounting surface of the charging console, the X-ray control unit controls the X-ray irradiation device using the reception signal received from the charging console control unit, and when the mounting detection unit does not detect that the operation console is mounted on the mounting surface of the charging console, the X-ray control unit controls the X-ray irradiation device using the reception signal received from the main body receiving unit. Effect of the Invention

[0009] According to the present invention, since the operator console transmits a wireless signal, the operator console can be carried to a desired location for use, improving convenience. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] <<Embodiment 1>> An X-ray fluoroscopy apparatus 1 according to a first embodiment will be described with reference to the drawings. Figs. 1 to 4 are block diagrams showing the overall configuration of the X-ray fluoroscopy apparatus according to the first embodiment. Fig. 5 is a block diagram showing the configuration of an operation console and a fixed charging console 200. Fig. 6 is a block diagram showing the configuration of a close-by charging console. Figs. 7 and 8 are a block diagram and a perspective view showing the configuration of a table-side charging console.

[0013] The X-ray fluoroscopic imaging device 1 is configured to include an imaging device main body 500, a portable operation table 100, a fixed charging table 200 that supplies power to the operation table 100, a proximity charging table 300, and a tableside charging table 400. The imaging device main body 500, the proximity charging table 300, and the tableside charging table 400 are arranged in an examination room 2, and the fixed charging table 200 is arranged in an operation room 3 that is shielded from the examination room 2 by an X-ray shielding plate 4. The fixed charging table 200 is fixed within the operation room 3. The tableside charging table 400 is fixed to a table 510 of the imaging device main body 500. The proximity charging table 300 is movable within the examination room 2.

[0014] The imaging apparatus main body 500 is configured to include a table 510, an X-ray irradiator 520 that irradiates X-rays onto the subject 10 placed on the table 510, an X-ray detector 530 that detects X-rays that have passed through the subject 10, and an X-ray control unit 570 that controls the X-ray irradiator 520. Here, the X-ray irradiator 520 and the X-ray detector are disposed opposite each other by a C-arm 540. The C-arm 540 is supported by a drive mechanism 550 so as to be rotatable, etc.

[0015] The imaging device main body 500 is also provided with a stand 560 that supports the drive mechanism 550. A main body receiving antenna 580 is provided on the upper part of the stand 560 as a receiving unit for receiving a wireless signal from the operation console 100. The main body receiving antenna 580 has not only a receiving function but also a transmitting function in order to establish a wireless communication protocol with the transmitting antenna 102 of the operation console 100.

[0016] A control unit 570 is disposed inside the stand 560. The control unit 570 is connected to the fixed charging table 200 via a cable 600. The control unit 570 receives a signal from the main body receiving antenna 580 and a signal from the fixed charging table 200, and controls the X-ray irradiator 520, the X-ray detector 530, the driving mechanism 550, and the like.

[0017] An image generating unit (not shown) is also disposed within the stand 560, and processes the detection signal of the X-ray detector 530 under the control of the control unit 570 to generate a fluoroscopic image and a still image.

[0018] 5 to 7, the operation console 100 includes an operation unit 101 that receives operations from an operator, and a transmission antenna 102 that is an operation console transmission unit that transmits, by wireless signal, the operations received by the operation unit 101. The transmission antenna 102 has not only a transmission function but also a reception function in order to establish a wireless communication protocol between the main body reception antenna 580 and a charging console reception antenna 202 described later.

[0019] Furthermore, the operation console 100 is equipped with a power receiving coil 105, a battery 106, a mounting position detection unit 107, an acceleration sensor 104, and an operation console control unit 103. The power receiving coil 105 receives power supplied in a non-contact manner and stores it in the battery 106.

[0020] The mounting position detection unit 107 at least detects whether the operation table 100 is mounted on the table side charging table 400. In this embodiment, the mounting position detection unit 107 is configured to detect whether the operation table 100 is mounted on any of the fixed charging table 200, the proximity charging table 300, and the table side charging table 400.

[0021] The acceleration sensor 104 functions as a movement sensor that detects whether the console 100 is moving.

[0022] On the other hand, the fixed charging console 200 includes a mounting surface 201 for mounting the operation console 100 thereon, a mounting detection unit 204, a power transmitting coil 205, a charging console receiving antenna 202, and a charging console control unit 203, as shown in FIG.

[0023] The mounting detection unit 204 detects whether or not the operation console 100 is mounted on the mounting surface 201. For example, the mounting detection unit 204 can be configured by a microswitch.

[0024] The power transmitting coil 205 transmits electromagnetic waves to a power receiving unit of the operation console 100 mounted on the mounting surface, thereby supplying power to the operation console 100 in a non-contact manner. Although not shown, a power cable is connected to the power transmitting coil 205 to supply power.

[0025] The charging console receiving antenna 202 receives a wireless signal transmitted from the transmitting antenna 102 of the operation console 100. The charging console receiving antenna 202 has not only a receiving function but also a transmitting function in order to establish a wireless communication protocol with the transmitting antenna 102 of the operation console 100.

[0026] One end of a cable 600 is connected to the charging table control unit 203, and the other end of the cable 600 is connected to the X-ray control unit 570 of the imaging device main body 500. The charging table control unit 203 outputs the output of the mounted detection unit 204 to the X-ray control unit 570 via the cable 600. In addition, the charging table control unit 203 outputs a reception signal received by the charging table receiving antenna 202 to the X-ray control unit 570 via the cable 600.

[0027] Therefore, the X-ray control unit 570 receives a received signal received by the charging table receiving antenna 202 of the fixed charging table 200 via the cable 600, and also receives a received signal received by the main body receiving antenna 580 of the imaging device main body 500.

[0028] When the mounting detection unit 204 detects that the operation console 100 is mounted on the mounting surface of the fixed charging table 200, the X-ray control unit 570 controls the X-ray irradiation device 520 using the reception signal received from the charging table receiving antenna 202, and when the mounting detection unit 204 does not detect that the operation console 100 is mounted on the mounting surface of the fixed charging table 200, the X-ray control unit 570 controls the X-ray irradiation device 520 using the reception signal received from the main body receiving unit.

[0029] As shown in FIG. 6, the proximity charging table 300 is equipped with wheels 307 to enable movement within the examination room 2.

[0030] Further, the proximity charging table 300 is provided with a proximity charging table mounting surface 301 on which the operation table 100 is mounted. Inside the proximity charging table 300, a power transmitting coil 305 that charges the power receiving coil 105 of the operation table 100 mounted on the proximity charging table mounting surface 301 in a non-contact manner, a proximity charging table control unit 303, and a battery 306 are arranged.

[0031] 7 and 8, the table-side charging table 400 includes an attachment mechanism 410. The table-side charging table 400 is attached to a side surface of a table 510 of the imaging device main body 500 by the attachment mechanism 410.

[0032] The table-side charging console 400 has a table-side mounting surface 401 on which the operation console 100 is mounted. Inside the table-side charging console 400, a table-side power transmission coil 405 for charging the operation console 100 mounted on the table-side mounting surface, a control unit 403, and a battery 406 are arranged.

[0033] The mounting position detection unit 107 of the above-mentioned operation table 100 detects the convex portions 211, 311, 411 provided on the mounting surfaces 201, 301, 401 of the fixed charging table 200, the proximity charging table 300 and the tableside charging table 400, respectively, to detect whether the operation table 100 is mounted on any of the fixed charging table 200, the proximity charging table 300 and the tableside charging table 400.

[0034] Specifically, the mounting position detection unit 107 of the operation table 100 is configured to include a recess provided on the underside 110 of the operation table 100 to engage with the protrusions 211, 311, 411, and a photosensor disposed in the recess. 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 tableside charging table 400, the protrusions 211, 311, 411 of the mounting surfaces 201, 301, 401 are inserted into the recesses of the mounting position detection unit 107 on the underside of the operation table 100 and detected by the photosensor.

[0035] In this case, as shown in FIG. 9(a), the mounting position detection units 107 are arranged at four locations on the underside of the operation table 100, whereas the mounting surface 201 of the fixed charging table 200 has two protruding portions 211, the mounting surface 301 of the proximity charging table 300 has three protruding portions 211, and the mounting surface 401 of the tableside charging table 400 has four protruding portions 411 (see FIG. 9(b) to (d)).

[0036] Therefore, the operation console control unit 103 can detect whether the operation console 100 is mounted on the fixed charging table 200, the proximity charging table 300, or the table-side charging table 400 by recognizing how many of the four mounting position detection units 107 of the operation console 100 have detected the insertion of the convex part. Specifically, when two of the four mounting position detection units 107 have detected the insertion of the convex part, the operation console control unit 103 can detect that the operation console 100 is mounted on the fixed charging table 200 as shown in FIG. 1. When three of the four mounting position detection units 107 have detected the insertion of the convex part, the operation console 100 is mounted on the proximity charging table 300 as shown in FIG. 2. When four of the four mounting position detection units 107 have detected the insertion of the convex part, the operation console 100 is mounted on the table-side charging table as shown in FIG. 3.

[0037] When the mounting position detection unit detects that the device is mounted on the fixed charging table 200 and the proximity charging table 300, the operation table control unit 103 transmits a wireless signal from the transmission antenna 102 for all operations received by the operation unit 101.

[0038] When the operation console 100 is mounted on the table side charging console 400, the operation console control unit 103 prohibits (interlocks) the transmission of a wireless signal from the transmission antenna 102 for a predetermined type of operation among the operations accepted by the operation unit 101. The predetermined type of operation includes, for example, taking an X-ray still image. Since the table side charging console 400 is attached to the table 510 of the imaging device main body 500, an operator who operates the operation console 100 on the table side charging console 400 stands close to the table 510. If an X-ray still image is taken in this state, the operator is exposed to radiation because the X-ray dose during the X-ray still image taking is large. When the operation console 100 is mounted on the table side charging console 400, even if an operation for taking an X-ray still image is performed, the operation console control unit 103 prohibits the transmission of a wireless signal to prevent the image from being taken. Note that, since the dose of an X-ray fluoroscopic image is small, the image can be taken.

[0039] Further, the operator console 100 is provided with a movement sensor that detects whether the operator console 100 is moving or not.

[0040] When it is detected from the detection results of the four mounting position detection units 107 of the operation console 100 that the operation console 100 is not mounted on any of the fixed charging table 200, the proximity charging table 300, and the table-side charging table, the operation console control unit 103 receives the output of the acceleration sensor 104. When the acceleration sensor 104 detects acceleration in any direction, it determines that the operation console 100 is being carried by the operator (moving), and prohibits the transmission of wireless signals from the transmission antenna 102 for all operations accepted by the operation unit 101.

[0041] On the other hand, when the detection results of the four mounting position detection units 107 of the operation console 100 show that the operation console 100 is not mounted on any of the fixed charging table 200, the proximity charging table 300, or the table-side charging table, and the acceleration sensor 104 does not detect acceleration, the operation console control unit 103 determines that the operation console 100 is placed in a location that is not a charging unit in the examination room 2, as shown in Fig. 4. In this case, the operation console control unit 103 enables the transmission of wireless signals for all operations, enabling all operations.

[0042] Hereinafter, the operation of the X-ray control unit 570 will be described with reference to the flow of FIG.

[0043] The functions of the X-ray control unit 570 can be realized by software. In that case, the X-ray control unit 570 is configured by a computer or the like equipped with a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit) and a memory, and the CPU reads and executes a program stored in the memory to realize those functions. It is also possible to configure a part or the whole of the X-ray control unit 570 by hardware. For example, a circuit can be designed to realize the functions of each unit using a custom IC such as an ASIC (Application Specific Integrated Circuit) or a programmable IC such as an FPGA (Field-Programmable Gate Array).

[0044] (Step 1001) The X-ray control unit 570 receives the output of the mounting detection unit 204 and determines whether the operation console 100 is mounted on the mounting surface 201 of the fixed charging table 200. If the operation console 100 is mounted on the fixed charging table 200, the process proceeds to step 1002. If it is not detected that the operation console 100 is mounted on the fixed charging table 200, the process proceeds to step 1003.

[0045] (Step 1002) The X-ray control unit 570 uses a reception signal received from the charging table receiving antenna 202 via a cable 600 to control the X-ray irradiator 520 and the like to perform operations such as imaging.

[0046] (Step 1003) When the X-ray control unit 570 does not detect that the operation console 100 is mounted on the mounting surface of the fixed charging console 200, it uses the received signal received from the main body receiving antenna 580 to control the X-ray irradiation device 520, etc., to perform operations such as imaging.

[0047] In this way, when the operation console 100 is placed in the operation room 3 where the fixed charging console 200 is located, the X-ray control unit 570 selects the received signal received via the cable 600, and when the operation console 100 is not mounted on the fixed charging console 200, it can be determined that the operation console 100 is placed in the examination room 2, and therefore selects and controls the received signal received from the main body receiving antenna.

[0048] As a result, even if the wireless signal transmitted from the operation console 100 is received by both the charging console receiving antenna 202 in the operation room 3 and the main body receiving antenna 580 in the examination room 2, the X-ray control unit 570 can select the received signal and perform control. Therefore, it is possible to prevent malfunctions caused by receiving wireless signals indicating an operation twice, and to select the earliest received signal, thereby preventing time delays in the response to the operation.

[0049] Next, the operation of the console control unit 103 will be described with reference to FIG.

[0050] Like the X-ray control unit 570, the functions of the console control unit 103 can be realized by software, and can also be realized by hardware.

[0051] (Step 1101) The operator console control unit 103 determines the location where the operator console 100 is placed based on the outputs of the four mounting position detection units 107 .

[0052] (Step 1102) The console control unit 103 proceeds to step 1106 if two of the four mounting position detection units 107 have detected a protrusion (two are ON), and proceeds to step 1103 if two are not ON.

[0053] (Step 1106) The operation console control unit 103 determines that the operation console 100 is on the fixed charging console 200 as shown in Fig. 1, and operates as a remote operation console. That is, the operation console control unit 103 transmits wireless signals of all operations accepted by the operation unit 101 from the transmission antenna 102.

[0054] (Step 1103) In step 1103, if three of the four mounting position detectors 107 have detected a protrusion (all are ON), the operation console controller 103 proceeds to step 1107, and if not all are ON, the operation console controller 103 proceeds to step 1104.

[0055] (Step 1106) The operation console control unit 103 determines that the operation console 100 is on the proximity charging console 300 as shown in Fig. 2, and operates as a proximity operation console. That is, the operation console control unit 103 transmits wireless signals of all operations accepted by the operation unit 101 from the transmission antenna 102. At this time, the operation console control unit 103 ignores the output of the acceleration sensor 104.

[0056] (Step 1104) In step 1104, if all four mounting position detectors 107 have detected a protrusion (four are ON), the console controller 103 proceeds to step 1108, and if not all are ON, the console controller 103 proceeds to step 1105.

[0057] (Step 1108) The operation console control unit 103 determines that the operation console 100 is on the table-side charging console 400 as shown in Fig. 3, and operates as a table-side operation console. That is, the operation console control unit 103 prohibits (interlocks) the transmission of a wireless signal from the transmission antenna 102 for a predetermined type of operation (e.g., taking an X-ray still image) among the operations accepted by the operation unit 101. Other operations are transmitted from the transmission antenna 102.

[0058] This allows for prohibiting certain types of operations depending on the location of the console 100, thereby ensuring the safety of the operator and the subject 10, etc.

[0059] (Step 1105) The operator console control unit 103 determines that the operator console 100 is not placed on the charging console 200 , 300 , 400 , and proceeds to step 1109 .

[0060] (Step 1109) The operator console control unit 103 receives the output of the acceleration sensor 104, and if the output of the acceleration sensor is smaller than a threshold value, the process proceeds to step 1110, and if the output is equal to or greater than the threshold value, the process proceeds to step 1111.

[0061] (Step 1110) In step 1110, the operation console control unit 103 determines that the operation console 100 is placed in a location other than the charging consoles 300 and 400 in the examination room 2, as shown in FIG. 4. The operation console control unit 103 transmits wireless signals for all operations from the transmission antenna 102.

[0062] (Step 1111) On the other hand, in step 1111, if the acceleration sensor 104 detects acceleration in any direction, the operation console control unit 103 determines that the operation 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 operation unit 101.

[0063] Moreover, the operator console control unit 103 displays an error message on the connected display unit.

[0064] As described above, in the X-ray fluoroscopy apparatus 1 of this embodiment, the operation console 100 that transmits wireless signals can be placed in the operation room 3 and used as a fixed operation console, or it can be freely moved from the operation room 3 into the examination room 2 and used as a close-up operation console, or it can be placed next to the table 510.

[0065] At this time, the X-ray control unit 570 selects and uses the output of the main body receiving antenna 580 and the charging table receiving antenna 202 of the fixed charging table 200, so that no problems occur even if the wireless operation table 100 is moved and used.

[0066] In this way, a single wireless operation console 100 can be freely moved and used, thereby improving convenience for the operator, and since only one operation console 100 is required, the overall price of the X-ray fluoroscopy apparatus can be reduced.

[0067] In addition, when the wireless operation console 100 of the X-ray fluoroscopy apparatus 1 of this embodiment is placed on the table side in the examination room 2 and operated, certain types of operations such as taking X-ray still images are prohibited (interlocked), thereby ensuring safety such as preventing exposure of the operator.

[0068] Furthermore, the proximity charging table 300 has a built-in battery 306, and no cables are connected to the proximity charging table 300 during X-ray inspection. This has the advantage that inspection can be easily performed while moving the proximity charging table 300.

[0069] In the above-described embodiment, the transmitting antenna 102 of the operation console 100 transmits information on operations received from a user to the charging console receiving antenna 202 of the fixed charging console 200 and the main body receiving antenna 580 of the main body 500, but it is also possible to configure the operation console 100 to transmit and / or receive information other than operation information.

[0070] For example, information on shooting conditions such as tube current and tube voltage, and the captured image can be wirelessly transmitted to the operation console 100 from the charging console receiving antenna 202 of the fixed charging console 200 or the main body receiving antenna 580 of the main body 500, and the transmitting antenna 102 of the operation console 100 can receive this information and display the shooting conditions such as tube current and tube voltage, the captured image, etc. on a display provided on the operation console 100.

[0071] <<Embodiment 2>> The X-ray fluoroscopic imaging apparatus of the second embodiment will be described with reference to Figs.

[0072] In the X-ray fluoroscopy apparatus of the first embodiment, the proximity charging table 300 has a built-in battery 306, so that the examination can be easily performed while moving the proximity charging table 300. In the second embodiment, in order to be able to handle an even longer X-ray examination, a spare battery 310 is further mounted on the battery 306 of the proximity charging table 300.
