Abstract

Dans le cadre de la présente invention, dans un environnement à accès à distance qui comprend un serveur, un dispositif client peut accéder à distance, par exemple, à des images médicales, à partir du serveur et peut avoir à sa disposition un mécanisme pour récupérer une image d'essai, telle que les mires d'essai d'échantillon TG-18 CT ou TG-18 MP. Le dispositif client communique des informations de taille d'affichage au serveur, qui produit l'image d'essai à la volée pour la taille d'affichage particulière du dispositif client. Par exemple, des composants dans l'image d'essai et des bordures peuvent être mis à échelle pour créer une image d'essai appropriée pour un quelconque dispositif client.
