Positioning system e.g. skin marker, for e.g. invasive surgical treatment, has registration module executing automatic picture to patient registration using data in patient and instrument data sets, and planning module planning trajectory

摘要

The system has a data processing unit (4) with an input module to receive patient and equipment data sets. The patient data set has image data and data for positioning a reference frame (2) in a coordination system (201). The equipment data set has two data to position the frame and a needle holder (3) in another coordination system (301). A registration module executes an automatic picture to patient registration using data in the data sets. A planning module plans a trajectory from an entry point to a target point in a patient (5). The frame has a rack formed from carbon or plastic material. Independent claims are also included for the following: (1) a reference frame for an application in a positioning system (2) an instrument holder such as a needle holder for an application in a positioning system (3) a medical instrument for an application in a positioning system (4) a computer program with a set of instructions for a positioning system for percutaneous intervention.
