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.

Method for calibrating a medical imaging device, method for performing a 2D-3D registration, and system including a medical imaging device

A method is disclosed for registration on setting an alignment of an instrument relative to an object during a processing or treatment of the object by the instrument. A working image is registered to a planning image. The working image is recorded in a viewing direction that is selected dependent upon relevant degrees of freedom of the instrument such that the relevant degrees of freedom are the degrees of freedom with the greater registration accuracy. In addition, a robot system is provided which is configured for carrying out the method.
