Definitions

  • the present invention relates to a data retrieval system and more particularly to interactive computer systems which permit the display of images and data stored on a server on a remote terminal of a user.
  • the remote terminal may be connected to the server via an internet connection or other form of network.
  • web pages are downloaded from a server in response to user commands. These pages may also contain programmes or applets which run on the remote terminal of the user in order to cause changes in the displayed page without further accesses to the server.
  • a user may be required to pay for access to that data.
  • One form of payment is to license use of the data for a specific period of time. Since a copy of the downloaded data is stored on the remote terminal of the user, there is a technical problem in controlling use once the data has been downloaded. It is necessary to provide some scheme to monitor the date of the downloaded file and the corresponding expiry of the licence.
  • the present invention is particularly concerned with the display of anatomical data although it will be appreciated that the system described would be equally applicable to other complex image data.
  • anatomical data For the purposes of this description, however, reference will be made to anatomical data by way of example.
  • Anatomical images contain a large number of specific structures. Identifying and labelling the structures within a particular image is challenging but is essential to the understanding of the image. For example the structures within an image of a hand include each of the bones, muscles, blood vessels, ligaments etc. In any given image a different part of the structure may be visible.
  • GB-A-2346786 addresses the problem of highlighting a structure within an image - in this case the geographical region of a country within a map- in response to user interaction with the image. It is also taught to display further information such as a list of wines for sale specific to the region. IBM does not address the problem of controlling use after download.
  • the further data can include a pattern applied over the area of the selected structure and/or a text label stored in the data table. Because the data set stored locally includes the substantial files, it is easy and quick for the user to scroll over the image. In order that the anatomical data can be understood explanatory text is needed. This text is preferably part of the additional further data downloaded in response to the user interaction with the primary image. Typically the selection will be made by the user clicking with his mouse on that area of the image showing the structure of interest.
  • an applet which is adapted to process user interactions with the image in order to generate a request for appropriate further data to the server is part of the initial data set downloaded onto the user terminal.
  • the downloaded data includes date information which is included in the data request generated by the applet to the server. If this date information is not current then the server will not respond to the request by transmitting the required data as the licence will have expired.
  • Figure 1 shows a diagrammatic representation indicating the relationship between the elements of a data set
  • Figure 2 is a block diagram of the computer network.
  • a user terminal is capable of connecting to a server 4 by means of a network connection 6. Typically this connection is over the Internet.
  • the server stores image data and associated text data.
  • Each individual image incorporates two separate image files 10, 12 representing a primary image and a secondary simplified image of the same subject.
  • the primary image file 10 is visible to the user when displayed on the user terminal. This visible image may be produced in JPEG format.
  • the secondary image 12 effectively labels the first image.
  • the secondary image is a false colour image of the same subject as depicted in the primary image. It is created by identifying each structure within the primary image 10 and rendering that structure in the secondary image 12 as a flat colour area coterminous with the boundaries of the structure in the primary image 10. These are false colours as they do not relate to the appearance of the subject.
  • the colours chosen for each structure are distinct. Any colour can be represented by distinct values of its red, green and blue (RGB) components.
  • RGB components of each colour represent "address data" of that particular structure. Accordingly, when a user clicks on any point within the primary image he is also clicking on the conesponding area of the underlying secondary image. The colour of that area of the secondary image represents a unique address which identifies the structure with which the user is interacting.
  • This data set includes primary and secondary image files.
  • the data set downloaded to the user's computer terminal 2 also incorporates an encrypted look-up table which contains the addresses identified by the false colour areas of the secondary image 12, the name of the associated structure and date data which will typically relate to the date on which the look-up table was downloaded.
  • the data set also includes an applet.
  • the applet is responsible for displaying the primary image and controlling the display when the user clicks on an area of interest in the primary image.
  • the applet decrypts the data table and checks the date stamp. If the data on the user's system clock is not within some specified time period of the date stamp, the applet will generate an enor message and refuse to display the image . If the date settings are within limits, the applet will generate a label when a user clicks on the image. This label is derived by generating a cross hatch (or other pattern) over the contiguous extent of the false colour area in the secondary image. This label is combined with the primary image to show the extent of the anatomical structure selected. The applet will then display the name of the selected anatomical structure. In addition the applet may send a request to the server for the complete anatomical notes on that structure.

Abstract

L'invention concerne un système d'accès commandé à des données constituées d'images et de texte. Ce système est conçu pour être utilisé sur une connexion de réseau, telle qu'Internet. Selon l'invention, un ensemble de données initialement téléchargé par l'utilisateur comprend des images primaires et secondaires qui représentent un objet complexe, tel qu'une image anatomique d'une partie du corps, cet objet comprenant un grand nombre de structures et une table de données contenant des données dates ainsi qu'une entrée pour chaque structure identifiée dans l'image. L'image secondaire est invisible pour l'utilisateur, mais elle identifie chaque structure à l'intérieur des images primaires comme zone contiguë d'une couleur en aplat servant à fournir dans ses données RVB les données d'adresse de couleur pour cette structure. L'ensemble de données initialement téléchargé contient également une applet qui extrait à partir des images primaires et secondaires une adresse de données pour la structure anatomique soulignant la partie de l'image sur laquelle l'utilisateur a cliqué. La table de données contenant les adresses de données contient également une date de téléchargement et elle est cryptée. L'applet compare les données cryptées avec la date de système utilisateur et fonctionne seulement si le téléchargement est en cours.
