Abstract

L'invention concerne un procédé et un appareil pour le stockage et l'affichage d'informations d'image médicale. Selon un mode de réalisation de la présente invention, le procédé de stockage des informations d'image médicale comprend les étapes de : obtention d'une image médicale d'un patient pour la confirmation d'une lésion ; détermination de savoir si des informations d'antécédents d'une image médicale antérieure associée à l'image médicale obtenue du patient sont stockées ; addition des informations concernant l'image médicale obtenue du patient aux informations d'antécédents de l'image médicale antérieure pour générer des informations d'antécédents mises à jour lorsque les informations d'antécédents sont stockées ; et stockage des informations d'antécédents mises à jour. Par conséquent, le temps pris pour rechercher des informations concernant des images médicales classiques et antérieures une par une peut être diminué et, par conséquent, une commodité est fournie à un utilisateur de/terminal client qui demande et reçoit des informations concernant une image médicale antérieure.
