ARRANGEMENT FOR IMAGING AN OBJECT INCLUDING A VESSEL USING MAGNETIC PARTICLE IMAGING

摘要

An arrangement (10) and a method for imaging an object including a vessel (400), using magnetic particle imaging is provided. An image of the vessel (400) is reconstructed based on a known concentration of the magnetic particles (100) within the vessel (400) and on vessel tree data about the progression of said vessel (400).The reconstruction comprises defining cylinder elements (440) around an approximated image and stepwise and separately adapting the radii of the cylinder elements by integrating over the signal intenity of the cylinder elements, wherein the radii are adapted such that the integrated signal intensity over the cylinder elements equals the intensity expected from the known concentration of the magnetic particles in the vessel.
