Abstract

A method for calibrating a medical imaging device in terms of an image acquisition geometry, a method for performing a two-dimensional-three-dimensional registration based on corresponding calibration data, and a corresponding system are provided. Multiple images of a phantom are acquired using the imaging device in different positions of the phantom. A corresponding motion of the phantom from one position to a respective next position is tracked by a tracking device to keep continuous track of a spatial relation between the phantom and the imaging device. The medical imaging device is then calibrated based on the acquired images, corresponding recorded poses of the imaging device, and the tracked motion of the phantom.
