Selon la présente invention, un dispositif de perfusion de liquide médical (400) transmet une demande d'acquisition entrée à un boîtier de commande (500). En réponse à la demande d'acquisition, le boîtier de commande (500) acquiert des données de commande d'imagerie d'un SIR (100). Les données de commande d'imagerie sont renvoyées du boîtier de commande (500) au dispositif de perfusion de liquide médical (400). Ce dispositif (400) définit au moins une partie des données de commande d'imagerie en tant qu'au moins une partie de données de condition de perfusion. On peut ainsi alléger la charge de travail de l'entrée des données de condition de perfusion pour le personnel médical. Toutefois, les données de commande d'imagerie s'avérant essentielles pour un tomodensitomètre (200) et existant de manière classique, aucune nouvelle création de données n'est nécessaire. On obtient donc un système d'imagerie fluoroscopique (1000) dans lequel au moins une partie de données de condition de perfusion peuvent être facilement définies au niveau du dispositif de perfusion de liquide médical (400).
