Description

図１に本発明が動作するネットワーク環境の一例を示す。但し、本発明の適用は以下に限定されるものではない。本発明ではネットワークで繋がれた複数機関の間で医療画像データを共有する為に、医療画像情報を格納するためのデータベース106と医療画像情報の所在情報を格納するインデックスデータベース105が何処かの機関に管理されていることが条件となっている。その1つの機関として医療画像を専門的に管理するデータセンター101が存在しても良い。またデータセンター101の機能が、何処かの医療機関の中に存在していても良い。以下ではデータセンター101は中心的な役割を担う拠点とする。検査機関（医療機関も含む）102は、ネットワークに接続される各要素（ノード）を表す。検査機関102は相互に診療所や中核病院と医療画像データを通信し得るよう通信回線で接続されている。検査機関102は診療所や中核病院からの医療画像の読影を依頼される機関である。ネットワーク103はノード間を繋ぐものである。ネットワーク情報記憶部 104は、ネットワーク103に繋がっているノードの通信上の距離や地図の情報を記憶している。医療画像データ107は本発明で実現される分散コピーされたものである。以下ではデータセンター101が存在するとして説明する。
図2に本発明が動作するデータセンター101内での構成の一例を示す。医療画像蓄積通信システム（PACS）201は医療画像を保存し、通信によりネットワーク接続される機器との間で医療画像データのやり取りを行う。医療画像データベース202は、PACS201内に格納され医療画像データが撮影日、患者名、撮影部位等の医療画像属性情報で検索可能に記憶されている。インデックスサーバ203は医療画像の所在を管理する。インデックスデータベース（DB）204はインデックスサーバ203内に格納され、医療画像が検査機関102の内部サーバか、検査機関102の外部に設けられる外部サーバにあるかなどの所在情報が前記医療画像属性情報で検索可能に記憶されている。インデックスデータベース（DB）204で用いる前記医療画像属性情報は、前記PACS201の医療画像データと前記所在情報の対応付けができれば良く、前記医療画像属性情報の一部を用いてもよい。距離計算サーバ（DB）205はネットワーク上の距離を計算する。ネットワークデータベース206は、前記内部サーバや外部サーバのネットワーク上の距離の計算に利用される。ルータ207はデータセンター101が接続されるローカルエリアネットワーク（LAN）103と外部へ繋がるインターネットなどの外部ネットワークに接続する。このデータセンター101の構成では3種類のサーバが存在するが、それは機能としてのサーバであり、必ずしも1台の物理的なサーバ機器や１つのプログラムとして独立している必要はなく、１つの機能を複数台の機器やプログラムで行っても良い。 FIG. 1 shows an example of a network environment in which the present invention operates. However, application of the present invention is not limited to the following. In the present invention, in order to share medical image data among a plurality of organizations connected by a network, a database 106 for storing medical image information and an index database 105 for storing location information of medical image information are somewhere. It is a condition that it is managed by. As one of the institutions, there may be a data center 101 that specially manages medical images. The function of the data center 101 may exist in some medical institution. In the following, the data center 101 is assumed to play a central role. A laboratory (including a medical institution) 102 represents each element (node) connected to the network. The inspection institution 102 is connected by a communication line so that medical image data can be communicated with a clinic and a core hospital. The inspection organization 102 is an organization requested to interpret medical images from a clinic or a core hospital. A network 103 connects nodes. The network information storage unit 104 stores communication distances and map information of nodes connected to the network 103. The medical image data 107 is a distributed copy realized by the present invention. In the following description, it is assumed that the data center 101 exists.
FIG. 2 shows an example of a configuration in the data center 101 in which the present invention operates. A medical image storage communication system (PACS) 201 stores medical images and exchanges medical image data with devices connected to the network by communication. The medical image database 202 is stored in the PACS 201 so that medical image data can be searched by medical image attribute information such as an imaging date, a patient name, and an imaging site. The index server 203 manages the location of medical images. An index database (DB) 204 is stored in the index server 203, and location information such as whether a medical image is an internal server of the inspection organization 102 or an external server provided outside the inspection organization 102 is the medical image attribute information. It is stored so that it can be searched. The medical image attribute information used in the index database (DB) 204 only needs to be able to associate the medical image data of the PACS 201 with the location information, and may use a part of the medical image attribute information. A distance calculation server (DB) 205 calculates a distance on the network. The network database 206 is used for calculating the distance between the internal server and external server on the network. The router 207 is connected to a local area network (LAN) 103 to which the data center 101 is connected and an external network such as the Internet connected to the outside. In this data center 101 configuration, there are three types of servers, which are servers as functions, and do not necessarily have to be independent as one physical server device or one program. A plurality of devices and programs may be used.
