Patent ID: 8897514

Claim:
A method for determining motion, relative position or deformation of an object or of at least two elements of an associated patient in order to synchronize a physiological condition perceived by the associated patient with a 2D data set, the method comprising: obtaining a 3D image data set of the object or the at least two elements when the associated patient is in a first shape, first absolute position, or first relative position; moving at least one of the elements and/or deforming the object of the associated patient to a second shape, second absolute position, or second relative position, different from the first shape, first absolute position, or first relative position; selectively obtaining the 2D data set of the object or the at least two elements while in the second shape, second absolute position, or second relative position, wherein the 2D data set corresponds to the physiological condition perceived by the associated patient; calculating a 3D image data set of the object or the at least two elements in the second shape, absolute, or relative position using said 2D image data set and said 3D image data set: and determining the motion, relative position or deformation of the object based on a comparison of the calculated 3D image data set with the obtained 3D image data set.
