- the operator of the portable device (the doctor, the radiographer) is positioning the subject in the vicinity of the subject.
- the shooting condition it becomes possible to change the shooting condition to an appropriate one according to the state of the subject by operating the portable device.
- the operator can remotely operate each medical device by operating the portable device.
- the operation control unit limits medical devices that are controlled due to the operation of the operation unit by the operator, the operator can respond according to the diagnosis or treatment content of the subject.
- the appropriate medical device can be operated reliably.
- the operation control unit enables the operation of the operation unit by the operator with respect to the medical device in use. It is preferable to invalidate the operation of the operation unit by the operator for other medical devices. Accordingly, the operator (doctor) can reliably remotely operate one medical device to be operated, and thus can reliably prevent the other medical device from being remotely operated by mistake. it can.
- the portable device further includes a touch panel including the display unit and the operation unit.
- the operation unit is displayed on the screen of the touch panel, shows the operation contents for each medical device and / or each medical device, and can be operated by the operator on each medical device. This is a simple operation image.
- the operation control unit enables the operator's operation on the operation image corresponding to the medical device in use, and controls the operator's operation on the operation image corresponding to the other medical device. It is preferable to disable it.
- the operation content for each medical device is displayed on the screen of the touch panel as the operation image (for example, a widget such as an icon or a text box), the operator operates the operation image, The medical device in use can be easily remotely operated. In addition, even if the operator operates an operation image corresponding to the other medical device that is not in use, the operation result becomes invalid, so that it is ensured that the other medical device is erroneously controlled. Can be prevented.
- the operation image for example, a widget such as an icon or a text box
- the touch panel operated by the operator since the touch panel operated by the operator has no irregularities on the surface, for example, if the surface of the touch panel is sterilized after surgery, the surface can be kept clean and prevent nosocomial infection. It is also possible to do.
- the operation image corresponding to the medical device in use is displayed larger than the operation image corresponding to the other medical device on the screen of the touch panel, the operator The operation image corresponding to the medical device inside can be easily operated.
- an end image for ending control of the medical device in use from the portable device is further displayed on the screen of the touch panel, and the operation is performed when the end image is operated by the operator. It is preferable that the control unit switches the operation of the operator with respect to the operation image corresponding to each medical device to an effective state. Thus, the operator can select the medical device to be used next by operating the end image.
- the operation control unit may operate the operation image corresponding to one medical device by the operator after the operation of the operator for the operation image corresponding to each medical device is switched to an effective state.
- the operation control unit may operate the operation image corresponding to one medical device by the operator after the operation of the operator for the operation image corresponding to each medical device is switched to an effective state.
- the portable device is preferably a tablet computer, a handheld computer, or a portable information terminal. With these portable devices, the portable device can be easily carried to the vicinity of the patient.
- the tablet computer does not have a keyboard or mouse and has no irregularities on the surface, for example, if the surface of the tablet computer is sterilized after surgery, the surface can be cleaned and nosocomial infections can be obtained. Can also be prevented.
- the portable device is preferably used in a state of being sealed in a sterilization bag.
- the sterilization bag may be a disposable transparent bag.
- the portable device further includes a transmission / reception setting unit that presets transmission / reception of signals by multi-access wireless communication between the communication unit and each medical device before controlling each medical device. Is preferred.

本実施形態に係る医療システム(放射線撮影システム、医療画像放送システム)10は、図1に示すように、例えば、医療機関の手術室12に適用される。なお、後述するように、本実施形態に係る医療システム10は、手術室12以外にも適用可能であるが、ここでは、一例として、手術室12に適用した場合について説明する。
以上のように構成される本実施形態に係る医療システム10の特徴的な機能(第1~第3の特徴的な機能)について、図6A~図10Bを参照しながら説明する。
第1の特徴的な機能では、先ず、透視撮影が開始されるまで、コンソール52の切替処理部180(図4参照)は、放射線出力装置22及び放射線撮影装置24(図1及び図2参照)を制御するマスタをコンソール52に維持すると共に、携帯機器48をスレーブに維持する。すなわち、手術中の医師18から口頭で患者16に対する透視撮影の開始の指示を受けると、技師54は、コンソール52を操作して撮影条件の設定等の作業を行う必要があるため、透視撮影を開始するまでは、コンソール52をマスタにしておく必要があるからである。
第2の特徴的な機能では、患者16に対して所定の診断又は処置を行うために、医師18が手元の携帯機器48を操作することにより、医師18が使用する手術器具よりも滅菌レベルが低い(医師18が直接操作することのできない)放射線出力装置22及び放射線撮影装置24、超音波診断装置30、又は、内視鏡装置32の各種の医療機器を遠隔操作により制御するというものである。
第3の特徴的な機能では、先ず、手術室12で患者16に対する手術が行われる前に、暗号化処理部142での暗号化処理に必要な公開鍵又は秘密鍵(暗号キー)を情報管理部152に記憶させると共に、医療機関内の他の医療関係者が所持する携帯機器120aにも暗号キーを事前に取得させる。
次に、本実施形態に係る医療システム10の動作について説明する。
図11のステップS1において、患者16(図1及び図2参照)に対する手術に先立ち、医療システム10に用いられる各装置間の通信設定が行われる。
次に、図12A~図12Cを参照して、第1の特徴的な機能による動作を説明する。
次に、図13を参照して、第2の特徴的な機能による動作を説明する。
次に、図14を参照して、第3の特徴的な機能による動作を説明する。
以上説明したように、本実施形態に係る医療システム10によれば、第1~第3の特徴的な機能を有することにより、下記の効果が得られる。
第1の特徴的な機能によれば、透視撮影の開始後に、放射線出力装置22及び放射線撮影装置24を制御する装置(マスタ)を、コンソール52から携帯機器48に切り替える。すなわち、携帯機器48及びコンソール52は、放射線出力装置22及び放射線撮影装置24を制御するためのマスタ及びスレーブの関係にある。透視撮影の開始前は、コンソール52がマスタであると共に携帯機器48がスレーブであり、透視撮影の開始後に、コンソール52がスレーブ、携帯機器48がマスタにそれぞれ切り替わる。
第2の特徴的な機能によれば、医師18による携帯機器48の操作部162の操作に起因して、操作内容に応じた信号(医療機器を制御するためのコマンド)が通信部130から操作対象の医療機器に送信され、該医療機器は、受信した信号に従って制御される。これにより、手術室12で患者16に対して手術を行っている医師18は、医療機器の操作者(例えば、技師54)に口頭で指示しなくても、又は、医師18が使用する手術器具よりも滅菌レベルが低い医療機器を直接操作できなくても、該医師18の手元に配置された携帯機器48の操作部162を操作することにより、当該医療機器を遠隔操作で制御することができる。このように、携帯機器48が各医療機器に対するリモートコントローラとして機能するので、医師18は、手術の進行状況に応じて、手元の携帯機器48を操作して所望の医療機器を制御することにより、該医療機器の遠隔操作を迅速且つ的確に行うことが可能となる。
第3の特徴的な機能によれば、患者16の診断又は処置に関わる動画像を、所定領域内に向けて、地上デジタルテレビ放送(我が国の場合には、エリアワンセグメント放送)により、リアルタイムで配信することができる。
第1~第3の特徴的な機能では、携帯機器48がタブレットPC、ハンドヘルドコンピュータ又はPDAであるため、患者16の近傍にまで該携帯機器48を容易に持ち運ぶことが可能となる。
本実施形態に係る医療システム10は、上記の説明に限定されることはなく、下記の構成(第1~第3変形例)を採用することも可能である。
本実施形態の第1変形例は、図15Aに示すように、医師18が指で表示部192の画面上の所望箇所をクリックすることにより、クリックした部分が画面の中心に表示されるように患者16に対する次回の撮影が行われ、その後、図15Bに示すように、次回の撮影で取得された画像が表示部192の画面上に表示された際、クリックした部分が画面の中心に表示されるというものである。ここでは、一例として、図6Aと同様に、透視撮影の動画像を表示部192の画面に表示する場合について説明する。
これまでの説明は、手術室12内で医師18が患者16に対して手術を行う場合を前提として説明した。
本実施形態の第3変形例は、図17に示すように、第2変形例(図16参照)を一部改変したものである。
