Abstract
Systems and methods for image guided surgery are disclosed herein. An example method can include: receiving a plurality of 2D projection images of an object at a plurality of projection angles during a first period of time; and receiving a position of an instrument relative to a tracking coordinate system during the first period of time. The method can also include registering the plurality of 2D projection images relative to the tracking coordinate system to obtain a transformation function that defines a relationship between a coordinate system of the plurality of 2D projection images and the tracking coordinate system; receiving an adjusted position of the instrument relative to the tracking coordinate system during a second period of time that is subsequent to the first period of time; and estimating an adjusted position of the instrument relative to the plurality of 2D projection images using the transformation function.
