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.

Abstract: 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.

Abstract: An agent delivery catheter including a first hollow tube and a second hollow tube that protrudes from a distal opening of the first hollow tube and defines an agent delivery lumen extending along the entire length of the catheter. The distal end of the first tube is coupled to the second tube to form an annular cavity between the first tube and the second tube, the annular cavity provided for accommodating a retractable stylet shaft. An adapting member is disposed on and coupled to a proximal end of a ceramic member and for receiving a distal end of the stylet shaft.

Abstract: The invention relates to an agent delivery catheter, comprising a first hollow tube and a second hollow tube 2 which protrudes from a distal opening of the first hollow tube 1 and defines an agent delivery lumen 3 extending along the entire length of the catheter, wherein: the distal end of the first tube 1 is coupled to the second tube 2 to form an annular cavity 4 between the first tube 1 and the second tube 2, the annular cavity 4 being configured to accommodate a retractable stylet shaft 5; a ceramic member 6 which is disposed at the distal end of the first tube 1, in particular distally with respect to the distal opening of the first tube 1, encompasses the second tube 2 and couples the first tube 1 to the second tube 2, in particular via a third hollow tube 23 which encompasses the first tube 1 and the ceramic member 6; and a protective shrink-fit tube 7 is disposed radially on the outside of the ceramic member 6 and extends over at least the length of the ceramic member 6.
