Abstract

L'invention concerne un dispositif de diagnostic d'image médicale (1) contenant un dispositif de fonctionnement (100) qui acquiert, à partir d'un système de réservation d'examen (115), des informations d'examen et des informations de personne examinée liées à des informations d'identification de personne examinée extraites d'un ticket de consultation ou analogue à l'aide d'un dispositif de lecture de données (114) ou analogue. Les informations d'examen et les informations de personne examinée sont affichées sur un écran d'enregistrement d'informations (31) et à la fin d'une période d'attente prescrite, le dispositif de fonctionnement (100) commute l'affichage de l'écran vers un écran de paramétrage de conditions de capture d'image (32). Sur l'écran de paramétrage de conditions de capture d'image (32) s'affichent des conditions de capture d'image correspondant aux informations d'examen affichées sur l'écran d'enregistrement d'information (31). À la fin d'une autre période d'attente prescrite, un traitement de préparation de capture d'image d'un dispositif de diagnostic d'image médicale (112) commence et l'instruction de début de capture d'image est exécutée manuellement. Grâce à cette configuration, la charge de travail est réduite.
