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.
