Document Type and Number:
WIPO Patent Application WO/2019/019048
Kind Code:
A1
Abstract:
A method for image tracking using an X-ray imaging system (10) during an interventional radiology procedure on a human or animal may comprise: acquiring a first image of an object (50) inside a human or animal with a first X-ray detector (30) of the X-ray imaging system (10); acquiring a second image of the object (50) with the X-ray imaging system (10) during the interventional radiology procedure, at a time later than acquiring the first image; determining a displacement of the first X-ray detector (30) based on the first image and the second image; moving the first X-ray detector (30) by the displacement, with an actuator (29) of the X-ray imaging system (10). The X-ray imaging system (10) comprises the first X-ray detector (30), the second X-ray detector (40) and the actuator (29). A spatial resolution of the first X-ray detector (30) is higher than a spatial resolution of the second X-ray detector (40).
