摘要：
A medical imaging device and a method for providing an image representation supporting positioning of an intervention device such as a wire tip (4) in a region of interest during an intervention is proposed. Therein, the following process steps are to be performed: (S1) acquiring a pre-live anatomy image (1) including a region of interest； (S2) acquiring a live anatomy image using a live image acquisition device comprising an adjustable collimator device； (S3) identifying a location (5) of the intervention device (4) within the live anatomy image； (S4) adjusting settings of the collimator device based on the identified location of the intervention device for subsequently acquiring a further live anatomy image representing the region of interest using the live image acquisition device with the collimator device being in the adjusted settings； and providing (S5) the image representation by merging information from the live anatomy image into the pre-live anatomy image.. Thereby, the intervention device may be continuously tracked and the collimator device may restrict a field of view to a location of the intervention device thereby significantly reducing an applied X-ray dose. Background anatomical information may be introduced into the final image representation using the pre-live anatomy image possibly having a higher image contrast than the live anatomy images.L'invention porte sur un dispositif d'imagerie médicale et sur un procédé de fourniture d'un support de représentation d'image lors du positionnement d'un dispositif d'intervention, tel qu'une pointe de fil (4), dans une région d'intérêt durant une intervention. Selon l'invention, les étapes de traitement suivantes doivent être réalisées : (S1) acquérir une image d'anatomie préalablement en direct (1) comprenant une région d'intérêt； (S2) acquérir une image d'anatomie en direct à l'aide d'un dispositif d'acquisition d'image en direct comprenant un dispositif de collimateur ajustable； (S3) identifier un emplac
