Abstract

In this mobile X-ray device, a monitor carriage 8 alone carries a battery unit 84 comprising an X-ray tube electricity supplying battery, with no X-ray tube electricity supplying battery being carried by an X-ray carriage 6. Since a cable 9 is provided, electrically connecting the X-ray carriage 6 to the monitor carriage 8 and supplying the power of the X-ray tube electricity supplying battery from the monitor carriage 8 to the X-ray carriage 6, a large capacity power can be supplied continuously to the X-ray carriage 6. In addition, since no X-ray tube electricity supplying battery is being carried by the X-ray carriage 6, the dimensions and the weight of the X-ray carriage 6 can be reduced, and the operational capability of the X-ray carriage 6 is not reduced. As a result, while maintaining the operational capability of the X-ray carriage 6, a large capacity power can be supplied continuously.

　本発明は、Ｘ線管を搭載し、走行可能に構成された走行台車を備えた移動型Ｘ線装置に関する。 The present invention relates to a mobile X-ray apparatus equipped with an X-ray tube and a traveling carriage configured to be able to travel.
　従来の移動型Ｘ線装置は、Ｘ線による透視・撮影を主目的として行わない手術室などの部屋にて使用するために、装置使用時の前後では本来の目的作業の邪魔にならないように移動可能な台車構造として設計されている。具体的には、Ｘ線を照射するＸ線管と、当該Ｘ線管を搭載し、走行可能に構成された走行台車とを備えている。走行台車の底部には車輪が設けられている。さらに、走行台車には、手動操作用のハンドルを設けており、操作者が手動操作用のハンドルを握って、走行台車を動かすことで、任意の場所に移動させて当該場所にて透視・撮影を行うことができる。 A conventional mobile X-ray apparatus is used in a room such as an operating room where X-rays are not mainly used for fluoroscopy and imaging, so that it is moved before and after using the apparatus so that it does not disturb the original intended work. Designed as a possible trolley structure. Specifically, it includes an X-ray tube for irradiating X-rays, and a traveling trolley mounted with the X-ray tube and configured to run. Wheels are provided at the bottom of the traveling cart. Further, the traveling cart is provided with a handle for manual operation, and the operator grips the handle for manual operation and moves the traveling cart to move to an arbitrary location and perform fluoroscopy / photographing at the location. It can be performed.
　また、装置の性質上、コンパクトさが求められる。そこで、被検体にＸ線を照射するＸ線管を搭載したユニット（Ｘ線台車）と、Ｘ線照射（透視・撮影）にて得られるＸ線画像を表示するモニタを搭載したユニット（モニタ台車）との２つのユニットにて構成される場合が多い（例えば、特許文献１、２参照）。 コ ン パ ク ト Also, the nature of the device requires compactness. Therefore, a unit equipped with an X-ray tube for irradiating the subject with X-rays (X-ray cart) and a unit equipped with a monitor for displaying an X-ray image obtained by X-ray irradiation (fluoroscopy / imaging) (monitor cart) ) In many cases (for example, see Patent Documents 1 and 2).
　移動型Ｘ線装置としては、入院中の患者（被検体）の病室で回診を行う回診用Ｘ線装置や、特許文献１、２のように手術室にて透視・撮影を行う外科用Ｘ線装置などがある。回診用Ｘ線装置の場合には、走行台車に支柱および支柱に支持されたアームを備え、アームにＸ線管を支持し、回診時に可搬型のＸ線検出器を病室のベッドに装填して透視・撮影を行う。外科用Ｘ線装置の場合には、走行台車にＣアームを備え、Ｘ線管およびＸ線検出器が互いに対向するようにＣアームにＸ線管およびＸ線検出器を支持し、Ｃアームを回転させることで、任意の位置や方向から透視・撮影を行う。 Examples of the mobile X-ray apparatus include a round-trip X-ray apparatus that performs round-trip in a hospital room of a patient (subject) who is hospitalized, and a surgical X-ray that performs fluoroscopy and imaging in an operating room as disclosed in Patent Documents 1 and 2. There are devices. In the case of a round-trip X-ray apparatus, a traveling carriage is provided with a column and an arm supported by the column, an X-ray tube is supported on the arm, and a portable X-ray detector is loaded on the bed of the hospital room at the round. Perform fluoroscopy and photography. In the case of a surgical X-ray apparatus, the traveling cart is provided with a C-arm, and the C-arm supports the X-ray tube and the X-ray detector so that the X-ray tube and the X-ray detector face each other. By rotating, fluoroscopy and imaging are performed from any position and direction.
　従来の移動型Ｘ線装置においては、装置システムを稼働させる電力は、装置に付属する電源ケーブルを、電力を供給する商用電源コンセントに電気的に接続することで得ている。そのために、電源事情が悪い、または電源が近くにない場所での装置の使用は不可能である。このような場所において装置を使用しようとする場合には、装置付近に簡易型の発電機を用意するか、電力を事前に蓄積しておいたバッテリ等を装置に電気的に接続するか、またはバッテリを内蔵した装置を使用する必要がある。特許文献１、２ではＸ線管を搭載した走行台車（Ｘ線台車）にバッテリを内蔵している。 In a conventional mobile X-ray apparatus, power for operating the apparatus system is obtained by electrically connecting a power cable attached to the apparatus to a commercial power outlet supplying the power. Therefore, it is impossible to use the device in a place where the power supply is poor or where the power supply is not close. When attempting to use the device in such a place, prepare a simple generator near the device, connect a battery or the like that has stored electric power in advance to the device, or It is necessary to use a device with a built-in battery. In Patent Literatures 1 and 2, a battery is built in a traveling cart (X-ray cart) equipped with an X-ray tube.

　しかしながら、バッテリを装置に内蔵する場合、ある程度の期間に大容量の電力を継続して供給することができるように大型のバッテリを使用する必要があるという問題点がある。特に、Ｘ線管からのＸ線の照射（曝射）に大容量の電力が必要となる。
　大型のバッテリは寸法および重量が大きい。よって、Ｘ線管を搭載した走行台車（Ｘ線台車）に大型のバッテリを内蔵すると、その重量から走行台車の移動が困難となる。また、大型のバッテリを内蔵することによって走行台車（Ｘ線台車）自体の寸法が大きくなり被検体への接近が困難となる。このように大型のバッテリを内蔵すると走行台車の操作性が低くなる。 However, when a battery is incorporated in a device, there is a problem that a large battery needs to be used so that a large amount of power can be continuously supplied for a certain period. In particular, a large amount of electric power is required for X-ray irradiation (irradiation) from an X-ray tube.
Large batteries are large in size and weight. Therefore, if a large battery is built in a traveling vehicle (X-ray vehicle) equipped with an X-ray tube, the weight of the battery makes it difficult to move the traveling vehicle. In addition, by incorporating a large battery, the size of the traveling vehicle (X-ray vehicle) itself becomes large, and it becomes difficult to approach the subject. When such a large battery is built in, the operability of the traveling vehicle decreases.
　本発明は、このような事情に鑑みてなされたものであって、走行台車の操作性を保ちつつ、大容量の電力を継続して供給することができる移動型Ｘ線装置を提供することを目的とする。 The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a mobile X-ray apparatus capable of continuously supplying a large amount of power while maintaining the operability of a traveling vehicle.

By providing a cable and supplying the electric power of the X-ray tube power supply battery from the monitor cart to the traveling cart, a large amount of power can be continuously supplied to the traveling cart. Further, since the X-ray tube power supply battery is not mounted on the traveling vehicle, the size and weight of the traveling vehicle can be reduced, and the operability of the traveling vehicle does not decrease. As a result, it is possible to continuously supply a large amount of power while maintaining the operability of the traveling vehicle.
　また、本発明に係る移動型Ｘ線装置において、電源コンセントに接続可能な電源ケーブルをモニタ台車に電気的に接続し、当該電源コンセントに当該電源ケーブルを電気的に接続することで得られた電力をＸ線管給電用バッテリに充電する制御を行う制御手段をモニタ台車に搭載するのが好ましい。 Further, in the mobile X-ray apparatus according to the present invention, the power obtained by electrically connecting the power cable connectable to the power outlet to the monitor trolley and electrically connecting the power cable to the power outlet is provided.

The X-ray detector 4 is configured to move. The X-ray tube 3 irradiates the subject M with X-rays, and the X-ray detector 4 detects X-rays transmitted through the subject M. In FIG. 1, the X-ray detector 4 is composed of an image intensifier (II), but if it is a commonly used X-ray detector, a flat panel X-ray detector (FPD: @Flat There is no particular limitation as exemplified in Panel {Detector). The surgical X-ray apparatus 1 corresponds to a mobile X-ray apparatus according to the present invention.
　この他に、外科用Ｘ線装置１は、一端でＸ線管３を保持し、他端でＸ線検出器４を保持するＣアーム５と、Ｘ線管３，Ｘ線検出器４およびＣアーム５を搭載し、走行可能に構成されたＸ線台車６と、Ｘ線検出器３で得られたＸ線画像を表示するモニタ７（図２および図３を参照）を搭載し、走行可能に構成されたモニタ台車８（図２および図３を参照）と、Ｘ線管３やＸ線検出器４やＸ線台車６とモニタ台車８とを電気的に接続するケーブル９とを備えている。Ｘ線台車６は、本発明における走行台車に相当する。 In addition, the surgical X-ray apparatus 1 includes a C-arm 5 that holds the X-ray tube 3 at one end and an X-ray detector 4 at the other end, and the X-ray tube 3, X-ray detectors 4 and C An X-ray trolley 6, which is equipped with an arm 5 and is operable, and a monitor 7 (see FIGS. 2 and 3) for displaying an X-ray image obtained by the X-ray detector 3, are operable. And an X-ray tube 3, an X-ray detector 4, a cable 9 for electrically connecting the X-ray trolley 6 to the monitor trolley 8. I have. The X-ray trolley 6 is equivalent to the traveling trolley in the present invention.
　Ｃアーム５は、Ｘ線台車６に保持され当該Ｘ線台車６に対して移動可能に構成されている。Ｃアーム５は、回転中心軸ｘ方向に湾曲状に形成されている。Ｃアーム５は、本実施例では、Ｃアーム５自身に沿って回転中心軸ｘと直交する軸ｙの軸心周りに（矢印ＲＡ方向に）回転することで、Ｃアーム５に保持されたＸ線管３およびＸ線検出器４も同方向に回転することが可能である。さらに、Ｃアーム５は回転中心軸ｘの軸心周りに（矢印ＲＢ方向に）回転することで、Ｘ線管４およびＸ線検出器５も同方向に回転することが可能であり、Ｃアーム５は鉛直軸の軸心周りに（矢印ＲＣ方向に）回転（すなわち旋回）することで、Ｘ線管４およびＸ線検出器５も同方向に回転（旋回）することが可能である。 The C arm 5 is held by an X-ray trolley 6 and is configured to be movable with respect to the X-ray trolley 6. The C-arm 5 is formed in a curved shape in the rotation center axis x direction. In the present embodiment, the C-arm 5 is rotated along the C-arm 5 around the axis y of the axis y orthogonal to the rotation center axis x (in the direction of the arrow RA) to thereby hold the X-arm held by the C-arm 5. The tube 3 and the X-ray detector 4 can also rotate in the same direction. Furthermore, the X-ray tube 4 and the X-ray detector 5 can also rotate in the same direction by rotating the C-arm 5 about the rotation center axis x (in the direction of the arrow RB). The X-ray tube 5 and the X-ray detector 5 can also rotate (turn) in the same direction by rotating (turning) around the axis of the vertical axis (in the direction of the arrow RC).
　具体的に、Ｃアーム５は、図１に示すように、支柱１１，水平支持部１２およびアーム保持部１３を介して、Ｘ線台車６に保持されている。支柱１１は鉛直軸に沿って上下に昇降移動可能に回転可能で、支柱１１に保持されたＣアーム５ごとＸ線管４およびＸ線検出器５を昇降移動させることができる。水平支持部１２は、回転中心軸ｘ方向に平行な水平方向に進退移動可能であり、水平支持部１２に保持されたＣアーム５ごとＸ線管４およびＸ線検出器５を進退移動させることができる。 Specifically, as shown in FIG. 1, the C-arm 5 is held on the X-ray trolley 6 via a column 11, a horizontal support 12, and an arm holder 13. The column 11 is rotatable so as to be able to move up and down along the vertical axis, and the X-ray tube 4 and the X-ray detector 5 can be moved up and down together with the C-arm 5 held by the column 11. The horizontal support unit 12 can move forward and backward in a horizontal direction parallel to the rotation center axis x direction, and moves the X-ray tube 4 and the X-ray detector 5 together with the C arm 5 held by the horizontal support unit 12. Can be.
　また、水平支持部１２に対してアーム保持部１３を回転中心軸ｘの軸心周りに回転可能に保持することで、アーム保持部１３に保持されたＣアーム５ごとＸ線管３およびＸ線検出器４を回転中心軸ｘの軸心周りに（矢印ＲＡ方向に）回転させることができる。アーム保持部１３に対してＣアーム５を回転中心軸ｘと直交する軸ｙの軸心周りに回転可能に保持することで、Ｃアーム５ごとＸ線管３およびＸ線検出器４を軸ｙの軸心周りに（矢印ＲＢ方向に）回転させることができる。支柱１１に対して水平保持部１２を鉛直軸の軸心周りに保持することで、水平保持部１２およびアーム保持部１３に保持されたＣアーム５ごとＸ線管３およびＸ線検出器４を鉛直軸の軸心周りに（矢印ＲＣ方向に）回転（旋回）させることができる。 Further, by holding the arm holding portion 13 rotatably around the axis of the rotation center axis x with respect to the horizontal support portion 12, the X-ray tube 3 and the X-ray together with the C-arm 5 held by the arm holding portion 13 are provided. The detector 4 can be rotated around the axis of the rotation center axis x (in the direction of the arrow RA). The X-ray tube 3 and the X-ray detector 4 are held together with the C-arm 5 by holding the C-arm 5 rotatably around the axis y orthogonal to the rotation center axis x with respect to the arm holding unit 13. (In the direction of arrow RB). The X-ray tube 3 and the X-ray detector 4 are held together with the C-arm 5 held by the horizontal holding unit 12 and the arm holding unit 13 by holding the horizontal holding unit 12 around the vertical axis with respect to the column 11. It can be rotated (turned) around the axis of the vertical axis (in the direction of arrow RC).
　また、Ｃアーム５には、手動操作用のハンドル１４を設けており、操作者が手動操作用のハンドル１４を握って、Ｃアーム５ごとＸ線管３およびＸ線検出器４を軸ｙの軸心周りに（矢印ＲＡ方向に）手動で回転させ、Ｃアーム５ごとＸ線管３およびＸ線検出器４を回転中心軸ｘの軸心周りに（矢印ＲＢ方向に）手動で回転させ、Ｃアーム５ごとＸ線管４およびＸ線検出器５を鉛直軸の軸心周りに（矢印ＲＣ方向に）手動で回転（旋回）させることができる。また、支柱１１を鉛直軸に沿って上下に手動で昇降移動させて、支柱１１に保持されたＣアーム５ごとＸ線管４およびＸ線検出器５を手動で昇降移動させ、水平支持部１２を水平方向に手動で進退移動させて、水平支持部１２に保持されたＣアーム５ごとＸ線管４およびＸ線検出器５を手動で進退移動させることができる。 The C-arm 5 is provided with a handle 14 for manual operation. The operator holds the handle 14 for manual operation, and moves the X-ray tube 3 and the X-ray detector 4 together with the C-arm 5 along the axis y. Manually rotating about the axis (in the direction of arrow RA), and manually rotating the X-ray tube 3 and X-ray detector 4 together with the C-arm 5 (in the direction of arrow RB) about the axis of the rotation center axis x; The X-ray tube 4 and the X-ray detector 5 together with the C-arm 5 can be manually rotated (turned) around the axis of the vertical axis (in the direction of the arrow RC). Further, the column 11 is manually moved up and down along the vertical axis, and the X-ray tube 4 and the X-ray detector 5 together with the C-arm 5 held by the column 11 are moved up and down manually to move the horizontal support 12. The X-ray tube 4 and the X-ray detector 5 together with the C-arm 5 held by the horizontal support 12 can be manually advanced and retracted in the horizontal direction.
　なお、これらのＸ線管３，Ｘ線検出器４，Ｃアーム５，Ｘ線台車６，支柱１１，水平支持部１２およびアーム保持部１３はパワーバランス（重量バランス）が保たれるようにそれぞれが設計されており、これらがどの位置に移動しても重量により軸が傾くことがない。よって、操作者はこれらを手動で簡単に動かすことができる。 The X-ray tube 3, the X-ray detector 4, the C-arm 5, the X-ray trolley 6, the strut 11, the horizontal support unit 12, and the arm holding unit 13 are respectively controlled so that power balance (weight balance) is maintained. Are designed so that no matter where they move, the shaft does not tilt due to weight. Therefore, the operator can easily move these manually.
　Ｘ線台車６の底部には前輪６ａおよび後輪６ｂが設けられている。モータ６Ｍにより前輪６ａを駆動させて、操作者がＸ線台車６を押し引きして後輪６ｂを転がすことで、床面に対してＣアーム５ごとＸ線管３およびＸ線検出器４を水平方向に自在に移動させることができる。このように、本実施例に係るＸ線台車６は、モータ６Ｍにより手動をアシスト（支援）するように構成されている。もちろん、Ｘ線検出器４，Ｃアーム５，Ｘ線台車６，支柱１１，水平支持部１２およびアーム保持部１３を含んだ外科用Ｘ線装置１の総重量が軽ければ、必ずしもモータにより手動をアシスト（支援）しなくてもよい。なお、モータや駆動軸やピニオン等（いずれも図示省略）を備えて、Ｘ線管３，Ｘ線検出器４およびＣアーム５などの手動をアシスト（支援）するように構成してもよい。 A front wheel 6a and a rear wheel 6b are provided at the bottom of the X-ray trolley 6. The front wheel 6a is driven by the motor 6M, and the operator pushes and pulls the X-ray trolley 6 to roll the rear wheel 6b. It can be moved freely in the horizontal direction. As described above, the X-ray trolley 6 according to the present embodiment is configured to assist (assist) manual operation with the motor 6M. Of course, if the total weight of the surgical X-ray apparatus 1 including the X-ray detector 4, the C-arm 5, the X-ray trolley 6, the support 11, the horizontal support section 12, and the arm holding section 13 is light, manual operation by a motor is not necessarily performed. It is not necessary to provide assistance. It should be noted that a motor, a drive shaft, a pinion, etc. (all not shown) may be provided to assist the manual operation of the X-ray tube 3, X-ray detector 4, C-arm 5, and the like.
　このようにＣアーム５およびＸ線台車６が手動で動くことにより、Ｘ線管３，Ｘ線検出器４の両方が被検体Ｍに対して手動により動く。また、Ｘ線検出器４で検出されたＸ線に基づいて透視あるいは撮影を行う。撮影を行う場合には、通常の線量でＸ線管３から照射されて被検体Ｍを透過したＸ線をＸ線検出器４が検出して得られたＸ線検出信号に対してラグ補正やゲイン補正などの各種の処理を行ってＸ線画像を出力して、ＲＡＭ（Random-Access Memory）などで形成された記憶媒体（図示省略）に書き込んで記憶し、適宜必要に応じて、記憶媒体から読み出して、モニタ７（図２および図３を参照）に表示あるいはプリンタやフィルム等（図示省略）に印刷する。一方、透視を行う場合には、撮影のときよりも少ない線量でＸ線管３から連続的に照射されて被検体Ｍを透過したＸ線をＸ線検出器４が検出して得られた各々のＸ線検出信号に対してラグ補正やゲイン補正などの各種の処理をそれぞれ行って各々のＸ線画像を逐次に連続的にモニタ７に表示する。このように記憶媒体を介さずにモニタ７に直接的に表示することで、透視で得られた各々のＸ線画像を動画としてリアルタイムに表示することができる。なお、透視で得られた各々のＸ線画像を記憶媒体に書き込んで記憶してもよい。本実施例では、侵襲的な検査に使用される外科用Ｘ線装置１であるので、透視を専ら行うために用いられる。 こ と By manually moving the C-arm 5 and the X-ray carriage 6 in this manner, both the X-ray tube 3 and the X-ray detector 4 are manually moved with respect to the subject M. Further, fluoroscopy or imaging is performed based on the X-rays detected by the X-ray detector 4. When performing imaging, the X-ray detector 4 detects X-rays emitted from the X-ray tube 3 at a normal dose and transmitted through the subject M. An X-ray image is output by performing various processes such as gain correction, and is written and stored in a storage medium (not shown) formed of a RAM (Random-Access Memory) or the like. And display it on the monitor 7 (see FIGS. 2 and 3) or print it on a printer or film (not shown). On the other hand, in the case of performing fluoroscopy, the X-ray detector 4 detects X-rays that are continuously irradiated from the X-ray tube 3 at a smaller dose than that at the time of imaging and transmitted through the subject M, and are obtained. The X-ray detection signal is subjected to various processes such as lag correction and gain correction, and the X-ray images are sequentially and continuously displayed on the monitor 7. By directly displaying the X-ray image on the monitor 7 without using a storage medium as described above, each X-ray image obtained through fluoroscopy can be displayed in real time as a moving image. Each X-ray image obtained by fluoroscopy may be written and stored in a storage medium. In the present embodiment, since the surgical X-ray apparatus 1 is used for an invasive examination, it is used for exclusively performing fluoroscopy.
　図２および図３に示すように、モニタ台車８はモニタ７を搭載している。本実施例では、モニタ７を２つ設置しており、一方がリアルタイムにＸ線画像を表示する透視用のライブモニタであり、他方が過去に得られたＸ線画像を参照用に表示するリファレンスモニタである。もちろん、モニタの数については特に限定されず、透視用のライブモニタのみを備えてもよい。Ｘ線台車６と同様に、モニタ台車８についても、底部に前輪８ａおよび後輪８ｂが設けられており、これらの前輪８ａおよび後輪８ｂを転がすことで床面に対してモニタ台車８を水平方向に自在に移動させることができる。モニタ台車８についても、モータなどによりモニタ台車８の手動をアシスト（支援）するように構成してもよい。 モ ニ タ As shown in FIGS. 2 and 3, the monitor cart 8 has a monitor 7 mounted thereon. In this embodiment, two monitors 7 are installed, one of which is a live monitor for fluoroscopy that displays an X-ray image in real time, and the other is a reference that displays an X-ray image obtained in the past for reference. Monitor. Of course, the number of monitors is not particularly limited, and only a live monitor for fluoroscopy may be provided. Similarly to the X-ray trolley 6, the monitor trolley 8 is also provided with a front wheel 8a and a rear wheel 8b at the bottom. It can be moved freely in any direction. The monitor cart 8 may also be configured to assist (assist) manual operation of the monitor cart 8 using a motor or the like.
　図３に示すように、ケーブル９は、Ｘ線管３やＸ線検出器４やＸ線台車６とモニタ台車８とを電気的に接続している。ケーブル９は、電源ケーブルおよび通信ケーブルで構成されている。 (3) As shown in FIG. 3, the cable 9 electrically connects the X-ray tube 3, the X-ray detector 4, the X-ray trolley 6, and the monitor trolley 8. The cable 9 includes a power cable and a communication cable.
　透視・撮影で得られたＸ線検出信号を、通信ケーブルを介してＸ線台車６からモニタ台車８に送信する。そして、モニタ台車８に搭載（内蔵）された画像処理部（図示省略）にてＸ線検出信号に対してラグ補正やゲイン補正などの各種の画像処理を行ってＸ線画像を出力して、当該Ｘ線画像をモニタ７やプリンタやフィルム等に送信する。本実施例では画像処理部をモニタ台車８に搭載することで、Ｘ線台車６の寸法・重量を小さくしている。ただし、後述するＸ線管給電用バッテリ８５（図４を参照）と比較すると画像処理部の寸法・重量は小さいので、Ｘ線台車６に画像処理部を搭載してもよいし、Ｘ線台車６およびモニタ台車８の両方に画像処理部をそれぞれ搭載してもよい。 (4) Transmit the X-ray detection signal obtained by fluoroscopy / imaging from the X-ray trolley 6 to the monitor trolley 8 via a communication cable. Then, an X-ray image is output by performing various image processing such as lag correction and gain correction on the X-ray detection signal by an image processing unit (not shown) mounted (built-in) on the monitor cart 8, The X-ray image is transmitted to the monitor 7, a printer, a film, or the like. In this embodiment, the size and weight of the X-ray trolley 6 are reduced by mounting the image processing unit on the monitor trolley 8. However, since the size and weight of the image processing unit are smaller than that of an X-ray tube power supply battery 85 (see FIG. 4) described later, the X-ray trolley 6 may be provided with an image processing unit. The image processing unit may be mounted on both the monitor cart 6 and the monitor cart 8.
　商用電源コンセントＣに接続可能な電源ケーブル８１（図４も参照）をモニタ台車８に電気的に接続している。電源ケーブル８１を商用電源コンセントＣに電気的に接続することにより、電源ケーブル８１からの電力をＸ線管給電用バッテリ８５に充電する。一方、ケーブル９の電源ケーブルは、Ｘ線管給電用バッテリ８５の電力をモニタ台車８からＸ線台車６に供給する。 (4) A power cable 81 (see also FIG. 4) connectable to the commercial power outlet C is electrically connected to the monitor cart 8. By electrically connecting the power cable 81 to the commercial power outlet C, the power from the power cable 81 is charged into the X-ray tube power supply battery 85. On the other hand, the power cable of the cable 9 supplies the electric power of the X-ray tube power supply battery 85 from the monitor cart 8 to the X-ray cart 6.
　図４に示すように、モニタ台車８は絶縁トランス８２と充放電制御ユニット８３とバッテリユニット８４とを備えている。絶縁トランス８２は、一次コイルと二次コイルとで構成されており、電源ケーブル８１に電気的に接続されている。このように絶縁トランス８２を構成することにより、商用電源コンセントＣ（図３を参照）からのノイズを絶縁トランス８２は遮断する。充放電制御ユニット８３は、本発明における制御手段に相当する。 (4) As shown in FIG. 4, the monitor cart 8 includes an insulating transformer 82, a charge / discharge control unit 83, and a battery unit 84. The insulation transformer 82 includes a primary coil and a secondary coil, and is electrically connected to the power cable 81. By configuring the insulating transformer 82 in this manner, the insulating transformer 82 blocks noise from the commercial power outlet C (see FIG. 3). The charge / discharge control unit 83 corresponds to a control unit in the present invention.
　また、絶縁トランス８２は充放電制御ユニット８３に電気的に接続されている。充放電制御ユニット８３はシステム電源（図示省略）を備えており、システム電源はＡＣ／ＤＣ変換器（図示省略）を備えている。これによって、商用電源コンセントＣからの商用電力をＡＣ／ＤＣ変換器は交流（ＡＣ）から直流（ＤＣ）に変換する。 (4) The insulating transformer 82 is electrically connected to the charge / discharge control unit 83. The charge / discharge control unit 83 has a system power supply (not shown), and the system power supply has an AC / DC converter (not shown). Thus, the AC / DC converter converts the commercial power from the commercial power outlet C from alternating current (AC) to direct current (DC).
　また、充放電制御ユニット８３は、バッテリユニット８４およびケーブル９に電気的に接続されている。バッテリユニット８４は、複数のＸ線管給電用バッテリ８５が直列に接続されて構成されている。充放電制御ユニット８３をバッテリユニット８４に電気的に接続することにより、商用電源コンセントＣに電源ケーブル８１を電気的に接続することで得られた電力をＸ線管給電用バッテリ８５に充電する制御を充放電制御ユニット８３は行う。図４では、充放電制御ユニット８３はシステム電源の機能をも有していたが、システム電源と充放電制御ユニットとを別々にしてもよい。 (4) The charge / discharge control unit 83 is electrically connected to the battery unit 84 and the cable 9. The battery unit 84 includes a plurality of X-ray tube power supply batteries 85 connected in series. By electrically connecting the charge / discharge control unit 83 to the battery unit 84, control is performed to charge the X-ray tube power supply battery 85 with power obtained by electrically connecting the power cable 81 to the commercial power outlet C. Is performed by the charge / discharge control unit 83. In FIG. 4, the charge / discharge control unit 83 also has the function of the system power supply, but the system power supply and the charge / discharge control unit may be separate.
　また、図４に示すように、ケーブル９は後述するパワーインバータ６１および制御ユニット６２に電気的に接続されている。Ｘ線台車６はパワーインバータ６１と制御ユニット６２と高電圧発生ユニット６３とを備えている。パワーインバータ６１は、ＤＣ／ＡＣ変換器（図示省略）で構成されており、ケーブル９に電気的に接続されている。このようにパワーインバータ６１を構成することにより、パワーインバータ６１は直流（ＤＣ）から交流（ＡＣ）に変換する。 (4) As shown in FIG. 4, the cable 9 is electrically connected to a power inverter 61 and a control unit 62 described later. The X-ray trolley 6 includes a power inverter 61, a control unit 62, and a high voltage generation unit 63. The power inverter 61 is configured by a DC / AC converter (not shown), and is electrically connected to the cable 9. By configuring the power inverter 61 in this way, the power inverter 61 converts direct current (DC) into alternating current (AC).
　制御ユニット６２は電源回路（図示省略）を備えており、ケーブル９に電気的に接続されている。また、制御ユニット６２はパワーインバータ６１に電気的に接続されている。Ｘ線管給電用バッテリ８５からの電力供給時に、制御ユニット６２はパワーインバータ６１を制御する。図４では、制御ユニット６２は電源回路の機能をも有していたが、電源回路と制御ユニット６２とを別々にしてもよい。 The control unit 62 includes a power supply circuit (not shown), and is electrically connected to the cable 9. The control unit 62 is electrically connected to the power inverter 61. The control unit 62 controls the power inverter 61 when power is supplied from the X-ray tube power supply battery 85. In FIG. 4, the control unit 62 also has the function of the power supply circuit, but the power supply circuit and the control unit 62 may be separate.
　また、パワーインバータ６１は高電圧発生ユニット６３に電気的に接続されている。高電圧発生ユニット６３はＸ線管３（図１および図３も参照）に電気的に接続されている。Ｘ線管給電用バッテリ８５からの電力供給時に、ケーブル９の電源ケーブルを介して、Ｘ線管給電用バッテリ８５からの電力をパワーインバータ６１は直流（ＤＣ）から交流（ＡＣ）に変換する。パワーインバータ６１で交流（ＡＣ）に変換した電力を高電圧発生ユニット６３に供給し、高電圧発生ユニット６３はＸ線管用の高電圧（管電圧）を発生する。そして、管電圧をＸ線管３に付与することにより、Ｘ線管３はＸ線を発生する。 (4) The power inverter 61 is electrically connected to the high voltage generation unit 63. The high voltage generation unit 63 is electrically connected to the X-ray tube 3 (see also FIGS. 1 and 3). When power is supplied from the X-ray tube power supply battery 85, the power inverter 61 converts the power from the X-ray tube power supply battery 85 from direct current (DC) to alternating current (AC) via the power cable of the cable 9. The power converted into alternating current (AC) by the power inverter 61 is supplied to the high voltage generation unit 63, and the high voltage generation unit 63 generates a high voltage (tube voltage) for the X-ray tube. Then, by applying a tube voltage to the X-ray tube 3, the X-ray tube 3 generates X-rays.
　バッテリユニット８４は、複数のＸ線管給電用バッテリ８５からなるので、Ｘ線管給電用バッテリ８５からの電力は、高電圧発生ユニット６３を介してＸ線管３に供給されるが、Ｘ線管３以外の構成（例えば、画像処理部や図１のモータ６Ｍ）にも給電してもよい。つまり、Ｘ線管給電用バッテリ８５は、少なくともＸ線管３に給電さえすれば、Ｘ線管３以外の構成にも給電してもよい。 Since the battery unit 84 includes a plurality of X-ray tube power supply batteries 85, power from the X-ray tube power supply battery 85 is supplied to the X-ray tube 3 via the high voltage generation unit 63. Power may be supplied to components other than the tube 3 (for example, the image processing unit and the motor 6M in FIG. 1). That is, the X-ray tube power supply battery 85 may also supply power to components other than the X-ray tube 3 as long as it supplies at least the X-ray tube 3.
　制御ユニット６２および充放電制御ユニット８３は、集積回路(IC: Integrated Circuit)などで構成されている。図４の構成から明らかなように、従来ではＸ線台車に搭載されていたバッテリユニット（Ｘ線管給電用バッテリも含む）および充放電制御ユニット（システム電源も含む）を、モニタ台車６に搭載することに技術的特徴がある。 The control unit 62 and the charge / discharge control unit 83 are configured by an integrated circuit (IC: Integrated Circuit) or the like. As is clear from the configuration of FIG. 4, the battery unit (including the X-ray tube power supply battery) and the charging / discharging control unit (including the system power supply) conventionally mounted on the X-ray trolley are mounted on the monitor trolley 6. There are technical features in doing so.
　次に、一連の処理について、図５を参照して説明する。図５は、実施例に係る外科用Ｘ線装置を用いる際の一連の処理の流れを示すフローチャートである。図５のフローチャートでは、Ｘ線台車６（図１，図３および図４を参照）およびモニタ台車８（図２～図４を参照）の移動先の目的の場所に商用電源コンセントＣ（図３を参照）が設置されているものとして説明する。 Next, a series of processes will be described with reference to FIG. FIG. 5 is a flowchart illustrating a flow of a series of processes when using the surgical X-ray apparatus according to the embodiment. In the flowchart of FIG. 5, the commercial power outlet C (FIG. 3) is set at the destination where the X-ray trolley 6 (see FIGS. 1, 3 and 4) and the monitor trolley 8 (see FIGS. 2 to 4) move. ) Is described.
　（ステップＳ１）台車の移動
　Ｘ線台車６およびモニタ台車８をそれぞれ目的の場所（例えば手術室）にまで移動させる。このとき、各台車６，８を繋ぐケーブル９（図１，図３および図４を参照）を各台車６，８から取り外した状態で、個々の台車６，８をそれぞれ移動させてもよいし、ケーブル９を各台車６，８に電気的に接続した状態で、個々の台車６，８をそれぞれ移動させてもよい。 (Step S1) Movement of Cart The X-ray cart 6 and the monitor cart 8 are respectively moved to target places (for example, an operating room). At this time, while the cables 9 (see FIGS. 1, 3 and 4) connecting the carts 6 and 8 are detached from the carts 6 and 8, the individual carts 6 and 8 may be moved. In a state where the cable 9 is electrically connected to each of the carts 6, 8, the individual carts 6, 8 may be moved.
　台車６，８の移動時には、商用電源コンセントＣに電源ケーブル８１（図３および図４を参照）が電気的に接続されていない。商用電源コンセントＣに電源ケーブル８１が電気的に接続されているか否かを検出する接続検出回路（図示省略）を備える。例えば、電源ケーブル８１に電流が流れているか否かを検出する電流検出アンプで接続検出回路を構成し、電源ケーブル８１に流れる電流の有無によって接続の有無を検出する。なお、台車６，８の移動時には、商用電源コンセントＣに電源ケーブル８１が電気的に接続されていないのが明らかであるので、必ずしも接続検出回路を備える必要はない。 電源 When the carriages 6 and 8 are moving, the power cable 81 (see FIGS. 3 and 4) is not electrically connected to the commercial power outlet C. A connection detection circuit (not shown) for detecting whether or not the power cable 81 is electrically connected to the commercial power outlet C is provided. For example, a connection detection circuit is configured with a current detection amplifier that detects whether or not a current is flowing through the power cable 81, and the presence or absence of the connection is detected by the presence or absence of a current flowing through the power cable 81. When the carriages 6 and 8 are moved, it is clear that the power cable 81 is not electrically connected to the commercial power outlet C, so that it is not always necessary to provide the connection detection circuit.
　モータ６Ｍ（図１を参照）によりＸ線台車６の手動がアシスト（支援）され、モータによりモニタ台車８の手動がアシスト（支援）されている場合、各モータに給電される電力はＸ線管３（図１，図３および図４を参照）に給電される電力と比べると極めて小さい。したがって、上述したようにＸ線管給電用バッテリ８５（図４を参照）から各モータにそれぞれ給電してもよい。もちろん、Ｘ線管給電用バッテリ８５とは別の小型のバッテリを用意し、各々の小型のバッテリが、当該バッテリを搭載した台車の手動をアシスト（支援）するために、同一の台車に搭載されたモータにそれぞれ給電してもよい。 When the manual operation of the X-ray trolley 6 is assisted (assisted) by the motor 6M (see FIG. 1) and the manual operation of the monitor trolley 8 is assisted (assisted) by the motor, the electric power supplied to each motor is an X-ray tube. 3 (see FIG. 1, FIG. 3, and FIG. 4) is extremely small compared to the power supplied to the power supply. Therefore, as described above, power may be supplied to each motor from the X-ray tube power supply battery 85 (see FIG. 4). Of course, a small battery different from the X-ray tube power supply battery 85 is prepared, and each small battery is mounted on the same truck to assist the manual operation of the truck equipped with the battery. May be supplied to the respective motors.
　（ステップＳ２）商用電源コンセントに接続？
　操作者が商用電源コンセントＣに電源ケーブル８１のプラグを差し込むことで、商用電源コンセントＣに電源ケーブル８１を電気的に接続したのか否かを判断する。なお、上述した接続検出回路によって、接続の有無を自動的に認識してもよい。商用電源コンセントＣに電源ケーブル８１のプラグを差し込んだ場合には、ステップＳ３に進む。商用電源コンセントＣに電源ケーブル８１のプラグを差し込んでない場合には、商用電源コンセントＣに電源ケーブル８１のプラグを差し込むまで、ステップＳ２をループ待機する。 (Step S2) Connect to commercial power outlet?
The operator determines whether or not the power cable 81 is electrically connected to the commercial power outlet C by inserting the plug of the power cable 81 into the commercial power outlet C. The presence or absence of connection may be automatically recognized by the connection detection circuit described above. If the plug of the power cable 81 has been inserted into the commercial power outlet C, the process proceeds to step S3. If the plug of the power cable 81 is not inserted into the commercial power outlet C, the process waits in a loop in step S2 until the plug of the power cable 81 is inserted into the commercial power outlet C.
　（ステップＳ３）照射？
　Ｘ線管３からＸ線を照射するか否かを判断する。具体的には、Ｘ線照射開始のコマンドがモニタ台車８の充放電制御ユニット８３（図４を参照）に入力されたか否かを、充放電制御ユニット８３がチェックする。Ｘ線照射開始のコマンドが充放電制御ユニット８３に入力された場合には、Ｘ線管３からＸ線を照射すると判断する。Ｘ線照射開始のコマンドが充放電制御ユニット８３に入力されていない場合には、Ｘ線管３からＸ線を照射しないと判断する。Ｘ線管３からＸ線を照射すると判断した場合には、ステップＳ４に進む。Ｘ線管３からＸ線を照射しないと判断した場合には、ステップＳ５に進む。 (Step S3) Irradiation?
It is determined whether the X-ray tube 3 emits X-rays. Specifically, the charge / discharge control unit 83 checks whether or not a command to start X-ray irradiation has been input to the charge / discharge control unit 83 (see FIG. 4) of the monitor cart 8. When an X-ray irradiation start command is input to the charge / discharge control unit 83, it is determined that X-rays are irradiated from the X-ray tube 3. If the X-ray irradiation start command has not been input to the charge / discharge control unit 83, it is determined that the X-ray tube 3 does not emit X-rays. When it is determined that the X-ray tube 3 emits X-rays, the process proceeds to step S4. If it is determined that the X-ray tube 3 does not emit X-rays, the process proceeds to step S5.
　（ステップＳ４）バッテリ放電
　ステップＳ３でＸ線管３からＸ線を照射すると判断した場合には、Ｘ線管給電用バッテリ８５からの電力を、ケーブル９の電源ケーブルを介してＸ線台車６のＸ線管３に給電するために、Ｘ線管給電用バッテリ８５の放電を行う。Ｘ線管給電用バッテリ８５の放電によって、Ｘ線管給電用バッテリ８５からの電力をＸ線管３に供給して、Ｘ線管３からＸ線を照射する。そして、被検体Ｍ（図１および図３を参照）を透過したＸ線をＸ線検出器４（図１および図３を参照）が検出することによる透視・撮影を行う。透視・撮影で得られたＸ線検出信号を、ケーブル９の通信ケーブルを介してモニタ台車８に送信して、モニタ台車８の画像処理部（図示省略）にてＸ線検出信号に対して画像処理を行ってＸ線画像を出力する。そして、当該Ｘ線画像をモニタ７（図２および図３を参照）に送信してモニタ７に表示する。 (Step S4) Battery Discharge If it is determined in step S3 that X-rays are emitted from the X-ray tube 3, the power from the X-ray tube power supply battery 85 is supplied to the X-ray trolley 6 via the power cable of the cable 9. To supply power to the X-ray tube 3, the X-ray tube power supply battery 85 is discharged. By discharging the X-ray tube power supply battery 85, power from the X-ray tube power supply battery 85 is supplied to the X-ray tube 3, and X-rays are emitted from the X-ray tube 3. The X-ray detector 4 (see FIGS. 1 and 3) detects X-rays transmitted through the subject M (see FIGS. 1 and 3) to perform fluoroscopy and imaging. An X-ray detection signal obtained by fluoroscopy / imaging is transmitted to the monitor trolley 8 via the communication cable of the cable 9, and an image processing unit (not shown) of the monitor trolley 8 performs image processing on the X-ray detection signal. Processing is performed to output an X-ray image. Then, the X-ray image is transmitted to the monitor 7 (see FIGS. 2 and 3) and displayed on the monitor 7.
　（ステップＳ５）バッテリ充電
　ステップＳ３でＸ線管３からＸ線を照射しないと判断した場合には、ステップＳ２で商用電源コンセントＣに電源ケーブル８１のプラグを差し込んだ状態であるので、商用電源コンセントＣに電源ケーブル８１を電気的に接続することで得られた電力をＸ線管給電用バッテリ８５に充電する。そして、ステップＳ３に戻って、Ｘ線管３からＸ線を照射するまでステップＳ３，Ｓ５を繰り返す。 (Step S5) Battery Charging If it is determined in step S3 that X-rays are not irradiated from the X-ray tube 3, the plug of the power cable 81 is inserted into the commercial power outlet C in step S2. The electric power obtained by electrically connecting the power cable 81 to C is charged into the X-ray tube power supply battery 85. Then, returning to step S3, steps S3 and S5 are repeated until the X-ray tube 3 emits X-rays.
　ステップＳ３，Ｓ５から明らかなように、Ｘ線管給電用バッテリ８５への充電を完了する必要はない。Ｘ線照射開始のコマンドが充放電制御ユニット８３に入力されたか否かを、予め設定された時間毎に充放電制御ユニット８３がチェックし（ステップＳ３での照射の判断を行い）、Ｘ線管３からＸ線を照射する（Ｘ線照射開始のコマンドが入力される）までＸ線管給電用バッテリ８５への充電を引き続き行い、Ｘ線照射開始のコマンドが入力された時点でＸ線管給電用バッテリ８５への充電を中断すればよい。 As is clear from steps S3 and S5, it is not necessary to complete charging of the X-ray tube power supply battery 85. The charge / discharge control unit 83 checks at every preset time whether an X-ray irradiation start command has been input to the charge / discharge control unit 83 (determination of irradiation in step S3), and the X-ray tube The X-ray tube power supply battery 85 is continuously charged until the X-ray irradiation is started (the X-ray irradiation start command is input) from the point 3 and the X-ray tube power supply is started when the X-ray irradiation start command is input. The charging of the battery 85 may be interrupted.
　本実施例に係る外科用Ｘ線装置１によれば、Ｘ線管３を搭載し、走行可能に構成された走行台車（Ｘ線台車６）と、モニタ７を搭載し、走行可能に構成されたモニタ台車８とにユニットを２つに分ける。Ｘ線台車６にはＸ線管給電用バッテリを搭載せずに、モニタ台車８のみにＸ線管給電用バッテリ８５を搭載する。Ｘ線台車６とモニタ台車８とを電気的に接続し、Ｘ線管給電用バッテリ８５の電力をモニタ台車８からＸ線台車６に供給するケーブル９を備える。ケーブル９を備え、Ｘ線管給電用バッテリ８５の電力をモニタ台車８からＸ線台車６に供給することにより、大容量の電力をＸ線台車６に継続して供給することができる。また、Ｘ線台車６にはＸ線管給電用バッテリが搭載されていないので、Ｘ線台車６の寸法・重量を小さくすることができ、Ｘ線台車６の操作性が低くなることはない。その結果、Ｘ線台車６の操作性を保ちつつ、大容量の電力を継続して供給することができる。 According to the surgical X-ray apparatus 1 according to the present embodiment, the X-ray tube 3 is mounted, and the trolley (X-ray trolley 6) configured to be operable and the monitor 7 are mounted to be operable. The monitor trolley 8 is divided into two units. An X-ray tube power supply battery 85 is mounted only on the monitor vehicle 8 without mounting the X-ray tube power supply battery on the X-ray vehicle 6. The X-ray trolley 6 and the monitor trolley 8 are electrically connected to each other, and a cable 9 for supplying the power of the X-ray tube power supply battery 85 from the monitor trolley 8 to the X-ray trolley 6 is provided. By providing the cable 9 and supplying the power of the X-ray tube power supply battery 85 from the monitor cart 8 to the X-ray cart 6, a large amount of power can be continuously supplied to the X-ray cart 6. Further, since the X-ray trolley 6 is not equipped with the X-ray tube power supply battery, the size and weight of the X-ray trolley 6 can be reduced, and the operability of the X-ray trolley 6 does not decrease. As a result, it is possible to continuously supply a large amount of power while maintaining the operability of the X-ray trolley 6.
　また、本実施例では、電源コンセント（商用電源コンセントＣ）に接続可能な電源ケーブル８１をモニタ台車８に電気的に接続し、当該商用電源コンセントＣに当該電源ケーブル８１を電気的に接続することで得られた電力をＸ線管給電用バッテリ８５に充電する制御を行う制御手段（本実施例では充放電制御ユニット８３）をモニタ台車８に搭載するのが好ましい。 Further, in the present embodiment, the power cable 81 connectable to the power outlet (commercial power outlet C) is electrically connected to the monitor cart 8 and the power cable 81 is electrically connected to the commercial power outlet C. It is preferable that a control means (a charge / discharge control unit 83 in this embodiment) for controlling charging of the X-ray tube power supply battery 85 with the electric power obtained in step (1) is mounted on the monitor carriage 8.
　ここで、先行技術文献および本発明の特徴部分について述べる。
　特許文献１：特開２０１４－２００４３６号公報では、段落番号「００１２」に「…モニタ台車１１には、後に詳述するが、モニタ１２やモニタ制御部１３等の負荷回路をバッテリ駆動するためのバッテリが搭載されている。」と記載されている。一方、段落番号「００２４」に「…Ｃアーム台車３１側で比較的大きな電力が必要な動作をする場合に、モニタ台車内のバッテリを使って、モニタ台車内をバッテリ駆動にし、モニタ台車１１に供給予定だった電力を、Ｃアーム台車３１に分配することで、Ｃアーム台車３１に使用可能な電力を増加させる。…」と記載されている。このように、特許文献１では、走行台車（特許文献１ではＣアーム台車）に搭載されたバッテリ（特許文献１では曝射バッテリ）の電力を増やすために、モニタ台車にもバッテリを搭載して、当該バッテリの電力を走行台車（Ｃアーム台車）に供給することを特徴としている。 Here, the features of the prior art document and the present invention will be described.
Patent Document 1: In Japanese Patent Application Laid-Open No. 2014-200436, the paragraph number “0012” is replaced with “... a monitor cart 11, which will be described later in detail, but for driving a load circuit such as the monitor 12 and the monitor control unit 13 with a battery. A battery is mounted. " On the other hand, when the operation requiring relatively large power on the side of the C-arm trolley 31 is performed in the paragraph number “0024”, the inside of the monitor trolley is driven by the battery using the battery in the monitor trolley, and By distributing the power to be supplied to the C-arm trolley 31, the power available to the C-arm trolley 31 is increased .... ". As described above, in Patent Literature 1, in order to increase the power of the battery (the exposure battery in Patent Literature 1) mounted on the traveling trolley (the C-arm trolley in Patent Literature 1), the battery is also mounted on the monitor trolley. The power of the battery is supplied to a traveling cart (C-arm cart).
　これに対し、本発明では、走行台車にはＸ線管給電用バッテリを搭載せずに、走行台車の寸法・重量を小さくするという点で特許文献１：特開２０１４－２００４３６号公報と相違する。これによって、特許文献１における各モードに応じて各スイッチング回路のＯＮ／ＯＦＦを切り替えるという制御を行わずに、本発明では、照射時にはバッテリの放電を行い、それ以外の時にはバッテリの充電を行うという簡易な制御のみで済む効果をも奏する。 On the other hand, the present invention differs from Patent Document 1: Japanese Patent Application Laid-Open No. 2014-200436 in that the size and weight of the traveling vehicle are reduced without mounting the X-ray tube power supply battery on the traveling vehicle. . As a result, the present invention does not perform the control of switching the ON / OFF of each switching circuit according to each mode in Patent Document 1, but discharges the battery at the time of irradiation and charges the battery at other times. An effect that only simple control is sufficient can be obtained.
　本発明は、上記実施形態に限られることはなく、下記のように変形実施することができる。 The present invention is not limited to the above embodiment, but can be modified as follows.
　（１）上述した実施例では、外科用Ｘ線テレビシステムのような侵襲的な検査に使用される外科用Ｘ線装置を例に採って説明したが、回診用Ｘ線装置などに例示されるように、Ｘ線管を搭載し、走行可能に構成された走行台車（Ｘ線台車）と、モニタを搭載し、走行可能に構成されたモニタ台車とを備えた移動型Ｘ線装置であれば、特に限定されない。 (1) In the above-described embodiment, a surgical X-ray apparatus used for an invasive examination such as a surgical X-ray television system has been described as an example. As described above, a mobile X-ray apparatus equipped with a traveling vehicle (X-ray vehicle) equipped with an X-ray tube and capable of traveling, and a monitor vehicle equipped with a monitor and capable of traveling. Is not particularly limited.
　（２）上述したように、Ｘ線管給電用バッテリは、少なくともＸ線管に給電さえすればよく、Ｘ線管以外の構成（例えば、画像処理部や図１のモータ６Ｍ）にも給電してもよい。 (2) As described above, the X-ray tube power supply battery only needs to supply power to at least the X-ray tube, and also supplies power to components other than the X-ray tube (for example, the image processing unit and the motor 6M in FIG. 1). You may.
　（３）上述した実施例では、走行台車（Ｘ線台車）にはＸ線管給電用バッテリを含めて他のバッテリを搭載しなかったが、図５のフローチャートでも述べたように、Ｘ線管給電用バッテリとは別の小型のバッテリをＸ線台車に搭載してもよい。そして、当該小型のバッテリがＸ線管以外の構成に給電してもよい。 (3) In the above-described embodiment, the traveling trolley (X-ray trolley) does not include other batteries including the X-ray tube power supply battery. However, as described in the flowchart of FIG. A small battery different from the power supply battery may be mounted on the X-ray trolley. Then, the small battery may supply power to components other than the X-ray tube.
