Claim 12:
13. The X-ray overlay display method of claim 11, further comprising:
executing, by the X-ray overlay controller, a guiding overlay display mode including:
processing, by the X-ray overlay controller, 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-registering, by the X-ray overlay controller, the pair of interventional X-ray images based on the illustration of the guiding X-ray calibration device in the pair of interventional X-ray images;
generating, by the X-ray overlay controller, a simulated tool axis positioned within an X-ray imaging space of the C-arm based on a co-registration of the pair of interventional X-ray images;
processing, by the X-ray overlay controller, 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-registering, by the X-ray overlay controller, 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;
deriving, by the X-ray overlay controller, a guidance took 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
controlling, by the X-ray overlay controller, a display of the guidance took trajectory overlay onto the guiding X-ray image.
