Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 2:
3. The X-ray imaging system of claim 1, wherein the X-ray overlay controller (410) is configured in a guiding overlay display mode to:
process a pair of interventional X-ray images acquired by the C-arm at different interventional X-ray imaging poses of the C-arm, each interventional X-ray image being illustrative of a guiding X-ray calibration device and illustrative of the interventional tool;
co-register the pair of interventional X-ray images based on the illustrations of the guiding X-ray calibration device in the pair of interventional X-ray images;
generate a simulated tool axis virtually positioned within the X-ray imaging space of the C-arm based on a co-registration of the pair of interventional X-ray images;
process a guiding X-ray image acquired by the C-arm at a guiding X-ray imaging pose of the C-arm, the guiding X-ray image being illustrative of the guiding X-ray calibration device and non-illustrative of the interventional tool;
co-register the pair of interventional X-ray images and the guiding X-ray image based on the illustration of the guiding X-ray calibration device in the pair of interventional X-ray images and in the guiding X-ray image;
derive a guidance tool trajectory overlay from the simulated tool axis based on a co-registration of the pair of interventional X-ray images and the guiding X-ray image; and
control a display of the guidance tool trajectory overlay onto the guiding X-ray image.
