PROCÉDÉ POUR DÉTERMINER UNE INFORMATION DE RIGIDITÉ D'UN INSTRUMENT MÉDICAL, PROCÉDÉ DE PRISE EN CHARGE D'IMAGERIE PENDANT UNE INTERVENTION À INVASION MINIMALE, DISPOSITIF À RAYONS X, PROGRAMME INFORMATIQUE ET SUPPORT D'INFORMATIONS LISIBLE ÉLECTRONIQUEMENT
Method for determining a stiffness information of a medical instrument, method for imaging support during a minimally invasive interventional procedure, x-ray device, computer program and electronically readable storage mediumMethod for determining a stiffness information of a medical instrument (18, 19, 19') used during a minimally invasive interventional procedure in a vascular system (30) of a patient (6) by- recording a three-dimensional volume image (23) of the vascular system (30) at least in the intervention region,- deriving from the volume image (23) three-dimensional vessel course information, in particular including centerlines (31) and/or surface information and/or volume information for at least vessels used by the instrument (18, 19, 19') during the interventional procedure and/or the position of ostia (32) along at least a part of the vessels,- recording a two-dimensional projection image (33, 33') of the instrument (18, 19, 19') using an x-ray device (1), wherein the x-ray device (1) and/or the projection image (33, 33') are registered to the volume image (23), and- determining a stiffness information of the instrument (18, 19, 19') by evaluation of the projection image (33, 33') using segmentation information determined by segmenting the instrument (18, 19, 19') in the projection image (33, 33') and/or the vessel course information.
