Method for adjusting superposition of two-dimensional fluoroscopy medical data set of blood vessel in e.g. brain of human body, involves mapping two dimensional-position of vessel into three-dimensional position by projection technique

摘要

The method involves segmenting data set (18) of blood vessel (10). Two-dimensional position (16) of the blood vessel within data set is determined while inserting a catheter in blood vessel. The two dimensional-position of blood vessel is mapped into three-dimensional position (30) of blood vessel by projection technique. The geometric superposition model of blood vessel is adjusted in data set based on three-dimensional position of blood vessel. An independent claim is included for apparatus for adjusting superposition of a two-dimensional fluoroscopy medical data set of blood vessel in brain of human body.
