Description

本発明は、無線でＸ線撮影データと制御データを送受信可能な無線電子カセッテおよび、それを使ったＸ線撮影システムに関する。   The present invention relates to a wireless electronic cassette capable of transmitting and receiving X-ray imaging data and control data wirelessly, and an X-ray imaging system using the same.

最近、受けたＸ線の量に応じて電荷に変換する素子を平面に配置し、Ｘ線をデジタル値として取り込み、平面画像を形成するの放射線デジタル撮影システム（以下DRと称す）が発売されるようになった。DRはＸ線画像をデジタル値にすることによって、Ｘ線画像をコンピュータ上で処理、編集可能になる利点がある。   Recently, a radiation digital imaging system (hereinafter referred to as “DR”) has been put on the market, in which elements that convert charges according to the amount of received X-rays are arranged on a plane, X-rays are captured as digital values, and a planar image is formed. It became so. DR has the advantage that X-ray images can be processed and edited on a computer by converting the X-ray images into digital values.

このＤＲの形態は据え置き型だけでなく可搬型のものも開発され、あらゆる部位の撮影をＤＲで実施可能になった。なかでもデータ転送を無線で行い電池を内蔵するタイプのもの（以下無線電子カセッテと称す）はホストコンピュータと接続するためのケーブルがないためハンドリングに優れ、病院の撮影室のみならず、病室における撮影に関しても活躍が期待されている。   This type of DR has been developed not only for the stationary type but also for the portable type, and it has become possible to perform imaging of all parts in the DR. Among them, the type that transfers data wirelessly and has a built-in battery (hereinafter referred to as a wireless electronic cassette) is superior in handling because there is no cable for connecting to a host computer, and it can be taken not only in a hospital room but also in a hospital room. Is also expected to play an active role.

さて無線電子カセッテが内蔵する電池の容量には限りがある。万が一電池がなくなっていたことに気がつかずＸ線を照射した場合は、無線電子カセッテが正常に動作しないため、再撮影を余儀なくされる。このような余分な被ばくを未然に防ぐために、電池の残量を示すインジケータやブザーを設けて、操作者に電池切れの注意を促すことも考案されている（例えば、特許文献１参照。）。   Now, the capacity of the battery built into the wireless electronic cassette is limited. In the unlikely event that the battery is exhausted and X-rays are irradiated, the wireless electronic cassette does not operate normally, and re-imaging is forced. In order to prevent such excessive exposure, it has been devised to provide an indicator or buzzer indicating the remaining battery level to alert the operator that the battery has run out (see, for example, Patent Document 1).

ところで現在、通信品質を計測する方法が考案されており（例えば、特許文献２参照）、多方面への応用が期待されている。まさに上記のような無線電子カセッテにおいては、ホストコンピュータとの通信品質は非常に重要であり、この技術を使うことによって無線電子カセッテを使うＸ線撮影システムの使い勝手の向上が望まれている。
特開2000-347330号公報（第６―７、１５頁、第２図） 特開2003-244167号公報（第５頁、第５図） By the way, the method of measuring communication quality is devised now (for example, refer patent document 2), and the application to many fields is anticipated. In the wireless electronic cassette as described above, the communication quality with the host computer is very important, and it is desired to improve the usability of the X-ray imaging system using the wireless electronic cassette by using this technology.
Japanese Unexamined Patent Publication No. 2000-347330 (pages 6-7, 15 and 2) Japanese Unexamined Patent Publication No. 2003-244167 (page 5, FIG. 5)

しかしながら、ブザーで電池切れを通知する方法を使う場合、撮影室とＸ線照射ボタンを押下する制御室とは遮蔽されているため、ブザー音を撮影室から制御室へ伝えるスピーカを設置する必要があり、病院からその費用削減が要望されている。   However, when using a method of notifying the battery with a buzzer, since the imaging room and the control room where the X-ray irradiation button is pressed are shielded, it is necessary to install a speaker that transmits the buzzer sound from the imaging room to the control room. There is a demand for cost reduction from hospitals.

またインジケータで電池切れを報せる方法では、撮影姿勢によって制御室から患者の体の影になってインジケータが見えにくくなる場合があり、その新しい解決方法が求められている。   In addition, in the method of reporting battery exhaustion with an indicator, the indicator may become difficult to see due to the shadow of the patient's body from the control room depending on the photographing posture, and a new solution is demanded.

本発明の目的は、電池と、電池の残量を計測する機能と、ホストコンピュータと制御データを無線通信する機能を持つ無線電子カセッテであって、
該電池の残量が所定の値以下になったときに、ホストコンピュータに通知する無線電子カセッテと、それを用いるＸ線撮影システムによって上記課題を解決することである。 An object of the present invention is a wireless electronic cassette having a battery, a function of measuring the remaining amount of the battery, and a function of wirelessly communicating control data with a host computer,
It is an object of the present invention to solve the above problems by a wireless electronic cassette that notifies a host computer when the remaining amount of the battery becomes a predetermined value or less and an X-ray imaging system using the same.

以上説明したように電池と、電池の残量を計測する機能と、ホストコンピュータと制御データを無線通信する機能を持つ無線電子カセッテであって、
該電池の残量が所定の値以下になったときに、ホストコンピュータに通知する無線電子カセッテと、それを用いるＸ線撮影システムによって無線電子カセッテの電池切れを操作者が十分に把握できるためにＸ線の誤照射がないという従来のメリットを損なわないで、Ｘ線撮影室から制御室へ音声を伝えるスピーカを削減することができる。 As described above, a wireless electronic cassette having a battery, a function of measuring the remaining amount of the battery, and a function of wirelessly communicating control data with the host computer,
In order for the operator to fully know that the battery of the wireless electronic cassette has run out by the wireless electronic cassette notifying the host computer when the remaining battery level becomes a predetermined value or less and the X-ray imaging system using the wireless electronic cassette Speakers that transmit sound from the X-ray imaging room to the control room can be reduced without losing the conventional merit that there is no erroneous X-ray irradiation.

さらに、無線電子カセッテのインジケータが撮影室から見えない場合でも、ホストコンピュータに接続されたディスプレイによって無線電子カセッテの電池切れを知ることができるため、撮影技師がインジケータの見える方向を気にせずに患者を整体でき、肉体的・精神的負荷を減らせるというメリットがある。   Furthermore, even if the wireless electronic cassette indicator is not visible from the radiographing room, the display connected to the host computer can tell when the wireless electronic cassette is out of battery, so the radiographer can be patient without worrying about where the indicator is visible. Has the merit of being able to trim the body and reducing the physical and mental load.

（第一の実施例）
以下、本発明の第一の実施例について図面を参照して説明する。 (First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

図１に本実施例で使用するシステムを示す。   FIG. 1 shows a system used in this embodiment.

図１において、10はＸ線の撮影に使用する無線電子カセッテである。無線電子カセッテ10は、Ｘ線の強度に応じて電荷を発生する素子を平面に配置したセンサ11と、センサ11や他の制御回路に電源を供給する電池14と、撮影画像データや制御データを後述のホストコンピュータと送受信するための無線送受信部13、無線電子カセッテ10全体をコントロールするセンサ制御部12から構成される。   In FIG. 1, reference numeral 10 denotes a wireless electronic cassette used for X-ray imaging. The wireless electronic cassette 10 includes a sensor 11 in which elements that generate charges according to the intensity of X-rays are arranged on a plane, a battery 14 that supplies power to the sensor 11 and other control circuits, and captured image data and control data. A wireless transmission / reception unit 13 for transmission / reception with a host computer, which will be described later, and a sensor control unit 12 for controlling the entire wireless electronic cassette 10 are configured.

また21は無線電子カセッテ10で取得した画像を処理してプリンタ等に出力するホストコンピュータである。尚、ホストコンピュータ21は、ホストコンピュータ21全体の制御を司る画像生成制御部110、無線電子カセッテと撮影データや制御データを送受信するための無線送受信部111、照射野の抽出や階調処理、縮小補正等を実施する画像処理部112、画像処理部111で処理が終了した画像をプリンタや外部ストレージに出力する機能を司る画像出力部113で構成される。   Reference numeral 21 denotes a host computer that processes an image acquired by the wireless electronic cassette 10 and outputs it to a printer or the like. The host computer 21 includes an image generation control unit 110 that controls the host computer 21 as a whole, a wireless transmission / reception unit 111 for transmitting and receiving imaging data and control data to and from a wireless electronic cassette, irradiation field extraction, gradation processing, and reduction. An image processing unit 112 that performs correction and the like, and an image output unit 113 that controls the function of outputting an image that has been processed by the image processing unit 111 to a printer or an external storage.

また、画像生成制御部110には、複数の画像処理方法やシステムの状態を操作者に提示するためのディスプレイ４０と、複数の画像処理方法の中から部位に適した画像処理を操作者が選択する等のホストコンピュータ21の動作を制御・変更するために使用するマウス４１が接続されている。   In addition, the image generation control unit 110 includes a display 40 for presenting a plurality of image processing methods and system states to the operator, and the operator selects image processing suitable for the part from the plurality of image processing methods. A mouse 41 used for controlling / changing the operation of the host computer 21 is connected.

さらに、１はＸ線発生装置、９はＸ線発生装置１のＸ線照射タイミングを制御するための、Ｘ線照射ボタンである。Ｘ線発生装置１は、ホストコンピュータ２１に接続されていて、Ｘ線照射の開始と終了をＸ線発生装置１からホストコンピュータ２１に通知する。また、画像生成制御部110は、認識したシステム全体の状態によって、たとえＸ線照射ボタン9が押下された場合であってもＸ線発生装置がＸ線を照射することを禁止することができる。   Further, 1 is an X-ray generator, and 9 is an X-ray irradiation button for controlling the X-ray irradiation timing of the X-ray generator 1. The X-ray generator 1 is connected to the host computer 21 and notifies the host computer 21 of the start and end of X-ray irradiation. Further, the image generation control unit 110 can prohibit the X-ray generation apparatus from irradiating X-rays, even when the X-ray irradiation button 9 is pressed, depending on the recognized state of the entire system.

さて図２は、本発明の無線電子カセッテ11の電池切れを検出するための処理の流れを示したフローチャートである。以下このフローチャートを使用して本発明を説明する。   Now, FIG. 2 is a flowchart showing a flow of processing for detecting battery exhaustion of the wireless electronic cassette 11 of the present invention. The present invention will be described below using this flowchart.

まず、Step100にてセンサ制御部12が無線送受信部13を使って、ホストコンピュータ21が起動されているか否かを調べ、もしホストコンピュータ21が起動されていなければ処理を終了する。しかし、ホストコンピュータ21が起動されている場合はStep101に進む。次にStep101にて電池14を調べ、所定の値より残量が少ないか否かを判断する(Step102)。もし所定の値より残量が少ない場合はホストコンピュータ21に無線によって通知し(Step103)、Step100に進む。反対に所定の残量よりも多い場合は、何もしないでStep100に進む。   First, in Step 100, the sensor control unit 12 uses the wireless transmission / reception unit 13 to check whether the host computer 21 is activated. If the host computer 21 is not activated, the process is terminated. However, if the host computer 21 is activated, the process proceeds to Step 101. Next, in Step 101, the battery 14 is checked to determine whether the remaining amount is less than a predetermined value (Step 102). If the remaining amount is less than the predetermined value, the host computer 21 is notified by radio (Step 103), and the process proceeds to Step 100. On the other hand, if it is greater than the predetermined remaining amount, the process proceeds to Step 100 without doing anything.

尚、上記で電池14の残量を確認する工程における所定の残量は、無線電子カセッテ10がホストコンピュータ21と通信可能な電池残量以上である必要がある。これによって、無線電子カセッテ10は電池14の残量不足を確実にホストコンピュータ21に報告することができる。   Note that the predetermined remaining amount in the step of confirming the remaining amount of the battery 14 as described above needs to be equal to or more than the remaining amount of the battery in which the wireless electronic cassette 10 can communicate with the host computer 21. Thus, the wireless electronic cassette 10 can reliably report the shortage of the battery 14 to the host computer 21.

さて無線電子カセッテ10が上記のように動作した場合に、管理元であるホストコンピュータ21がどのように動作するかを図３を使って説明する。   Now, how the host computer 21 as the management source operates when the wireless electronic cassette 10 operates as described above will be described with reference to FIG.

Step200において、電池14の残量が所定の値以下であることを無線送受信部111経由で受信したか否かを確認し、もし受信していた場合Step203に進む。   In Step 200, it is confirmed whether or not it is received via the wireless transmission / reception unit 111 that the remaining capacity of the battery 14 is equal to or less than a predetermined value.

Step203では、画像生成制御部110に接続されたディスプレイ40に無線電子カセッテ10の電池残量が少ない旨の表示を行なう。次にStep204において画像生成制御部110は、Ｘ線発生装置１に対してＸ線照射ボタン９が押下された場合であってもＸ線を照射しないように制御する。   In Step 203, the display 40 connected to the image generation control unit 110 displays that the battery level of the wireless electronic cassette 10 is low. Next, in Step 204, the image generation control unit 110 controls the X-ray generator 1 not to emit X-rays even when the X-ray irradiation button 9 is pressed.

またStep200において、電池14の残量が所定の値以下であることを無線送受信部111経由で受信していない場合にはStep201に進む。   In Step 200, if it is not received via the wireless transmission / reception unit 111 that the remaining amount of the battery 14 is equal to or less than the predetermined value, the process proceeds to Step 201.

Step201において、画像生成制御部110は接続されたディスプレイ40を使って、無線電子カセッテ10の電池残量が十分であることを表示する。次にStep202において画像生成制御部110は、Ｘ線発生装置１に対してＸ線照射ボタン９が押下された場合にＸ線を照射できるようにする。   In Step 201, the image generation control unit 110 displays that the battery level of the wireless electronic cassette 10 is sufficient using the connected display 40. Next, in Step 202, the image generation control unit 110 enables X-ray irradiation when the X-ray irradiation button 9 is pressed on the X-ray generation apparatus 1.

尚、ホストコンピュータ21が無線電子カセッテ10との通信品質を計測可能であって、万が一に電波を遮蔽するもの等が原因で通信品質が所定の値以下のときには、無線電子カセッテ10から電池残量が所定の値以下の通知があったものとして扱い、ディスプレイに警告を出し、Ｘ線発生装置の照射を禁止しても良い。これは通信品質が悪いときの撮影を禁止し、通信品質が高いときに撮影を許可することで、撮影した場合の膨大な画像データや他の制御データを確実に受信でき、システム全体の動作を保障できる確立が高まるという利点がある。   If the host computer 21 can measure the communication quality with the wireless electronic cassette 10 and the communication quality is below a predetermined value due to something that shields radio waves, etc., the remaining battery level from the wireless electronic cassette 10 May be treated as having been notified below a predetermined value, a warning is given to the display, and irradiation of the X-ray generator may be prohibited. This prohibits shooting when the communication quality is poor, and allows shooting when the communication quality is high, so that a huge amount of image data and other control data can be reliably received when shooting, and the operation of the entire system can be controlled. There is an advantage that the establishment that can be guaranteed increases.

加えて、通信品質が悪い場合にはディスプレイ40には、電池残量がない場合の表示と異なり、通信品質が悪い旨を表示した方が良い。これによって操作者が、電池を交換すれば良いか、電波を遮蔽しているものを取り除けばよいのかの判断がつく。   In addition, when the communication quality is poor, it is better to display on the display 40 that the communication quality is poor, unlike the display when there is no remaining battery power. As a result, the operator can determine whether to replace the battery or to remove the shielded radio wave.

（第二の実施例）
本発明の第二の実施例を図１と図４を使って説明する。尚図１は、第一の実施例で既に説明したので、説明を省略する。 (Second embodiment)
A second embodiment of the present invention will be described with reference to FIGS. Since FIG. 1 has already been described in the first embodiment, a description thereof will be omitted.

さて図４は、本実施例の説明に使用する本発明の処理の流れを示したフローチャートである。以下このフローチャートを使用して本発明を説明する。   FIG. 4 is a flowchart showing the processing flow of the present invention used for the description of this embodiment. The present invention will be described below using this flowchart.

まず、Step300にてセンサ制御部12が無線送受信部13を使って、ホストコンピュータ21が起動されているか否かを調べ、もしホストコンピュータ21が起動されていなければ処理を終了する。しかし、ホストコンピュータ21が起動されている場合はStep301に進む。次にStep301にて電池14を調べ、所定の値より残量が多いか否かを判断する(Step302)。もし所定の値より残量が多い場合はホストコンピュータ21に無線によって通知し(Step303)、Step300に進む。反対に所定の残量よりも少ない場合は、何もしないでStep300に進む。   First, in step 300, the sensor control unit 12 uses the wireless transmission / reception unit 13 to check whether the host computer 21 is activated. If the host computer 21 is not activated, the process is terminated. However, if the host computer 21 is activated, the process proceeds to Step 301. Next, in Step 301, the battery 14 is checked to determine whether or not the remaining amount is greater than a predetermined value (Step 302). If the remaining amount is larger than the predetermined value, the host computer 21 is notified by radio (Step 303), and the process proceeds to Step 300. On the other hand, if it is less than the predetermined remaining amount, proceed to Step 300 without doing anything.

さて無線電子カセッテ10が上記のように動作した場合に、管理元であるホストコンピュータ21がどのように動作するかを図５を使って説明する。   Now, how the host computer 21 as the management source operates when the wireless electronic cassette 10 operates as described above will be described with reference to FIG.

Step400において、電池14の残量が所定の値以上であることを無線送受信部111経由で受信したか否かを確認し、もし受信していない場合Step403に進む。   In Step 400, it is confirmed whether or not the remaining amount of the battery 14 is received through the wireless transmission / reception unit 111, and if not, the process proceeds to Step 403.

Step403では、画像生成制御部110に接続されたディスプレイ40に無線電子カセッテ10の電池残量が少ない旨の表示を行なう。次にStep404において画像生成制御部110は、Ｘ線発生装置１に対してＸ線照射ボタン９が押下された場合であってもＸ線を照射しないように制御する。   In Step 403, the display 40 connected to the image generation control unit 110 displays that the wireless electronic cassette 10 is low in battery power. Next, in Step 404, the image generation control unit 110 controls the X-ray generator 1 not to emit X-rays even when the X-ray irradiation button 9 is pressed.

またStep400において、電池14の残量が所定の値以上であることを無線送受信部111経由で受信した場合にStep401に進む。   In Step 400, when it is received via the wireless transmission / reception unit 111 that the remaining amount of the battery 14 is equal to or greater than a predetermined value, the process proceeds to Step 401.

Step401では、画像生成制御部110は、接続されたディスプレイ40を使って、無線電子カセッテ10の電池残量が十分であることを報せる。次にStep402において画像生成制御部110は、Ｘ線発生装置１に対してＸ線照射ボタン９が押下された場合にＸ線を照射するように制御する。   In Step 401, the image generation control unit 110 uses the connected display 40 to report that the remaining battery level of the wireless electronic cassette 10 is sufficient. Next, in Step 402, the image generation control unit 110 controls the X-ray generator 1 to emit X-rays when the X-ray irradiation button 9 is pressed.

尚、ホストコンピュータ21が無線電子カセッテ10との通信品質を計測可能であって、万が一に電波を遮蔽するもの等が原因で通信品質が所定の値以下のときには、無線電子カセッテ10から電池残量が所定の値以上である通知がなかったものとして扱い、ディスプレイに警告を出し、Ｘ線発生装置の照射を禁止しても良い。これは、通信品質が悪い場合には、たとえ電池残量の通知を受け取ったとしても、撮影画像の膨大なデータや他の制御データを確実に受信できない場合があるからである。すなわち、高い通信品質を確保した状態で撮影するように操作者を誘導することで、撮影画像の膨大なデータや他の制御データを確実に受信できるシステムを提供できるという利点がある。   If the host computer 21 can measure the communication quality with the wireless electronic cassette 10 and the communication quality is below a predetermined value due to something that shields radio waves, etc., the remaining battery level from the wireless electronic cassette 10 May be treated as having not been notified that the value is equal to or greater than a predetermined value, a warning is given to the display, and irradiation of the X-ray generator may be prohibited. This is because if the communication quality is poor, even if a notification of the remaining battery level is received, a large amount of data of the photographed image and other control data may not be reliably received. That is, there is an advantage that it is possible to provide a system that can reliably receive a huge amount of data of a photographed image and other control data by guiding the operator to shoot in a state where high communication quality is ensured.

加えて、通信品質が悪い場合にはディスプレイ40には、電池残量がない場合の表示と異なり、通信品質が悪い旨を表示した方が良い。これによって操作者が、電池を交換すれば良いか、電波を遮蔽しているものを取り除けばよいのかの判断がつく。   In addition, when the communication quality is poor, it is better to display on the display 40 that the communication quality is poor, unlike the display when there is no remaining battery power. As a result, the operator can determine whether to replace the battery or to remove the shielded radio wave.
