The invention relates to a device and a method for the determination of the position of a catheter in a vascular system (). In this, the measured positions (r, r) of two magnetic localizers at the tip of a catheter are displaced by correction vectors (k, k) while optimizing a quality dimension. The quality dimension includes a component taking account both of the deviation of the measured positions (r, r) from the vascular layout and of the deviation of the associated orientation (r&#x2212;r) from the orientation of the vascular layout according to a vascular map. In addition, the quality dimension may include components which evaluate the measured shape of the catheter compared to the vascular map. An additional correction step can further ensure that the corrected positions (r', r&#x2033;) correspond to the preset fixed distance (d) of the localizers ().

Device and method for the determination of the position of a catheter in a vascular system

The present invention relates to an arrangement and a method for influencing and/or detecting magnetic particles in a region of action, in particular for monitoring of intra-cerebral or intra-cranial bleeding using Magnetic Particle Imaging (MPI). A common coupling unit per coil of a coil array is provided for coupling all signals for generating the magnetic fields to the set of common coils. Further, the same coils are used for acquiring detection signals. In this way a small scanner can be built that can be left permanently or can be provided periodically to the patient, in particular for bleeding monitoring.
