Classification: CPC A | IPC A

Claim 7:
8. The X-ray overlay controller of claim 6,
wherein the at least one processor is further operable in a guiding overlay display mode; and
wherein the non-transitory machine-readable storage medium is further encoded in the guiding overlay display mode with instructions executable by the at least one processor 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 illustration of the guiding X-ray calibration device in the pair of interventional X-ray images;
generate 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;
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.
