Abstract
In a method for the automatic alignment of a medical instrument with respect to a target point in a patient body such as, for subsequent removal of a tissue sample or for therapy of a tumor in the target point, using a computed tomography apparatus with fluoroscopy mode, a guidance system aligns the medical instrument at a paracentesis point of the patient body in a CT image plane, and the spatial coordinates of the CT image plane are determined for the guidance system.
