摘要

configuration for detecting and / or locating a magnetic material in an action region, processor, method for detecting and / or locating a magnetic material in an action region, processing method, and computer program for magnetic particle imaging (mpi) ), reconstruction requires knowledge of a so-called system function. This function describes the relationship between spatial position and frequency response and is currently measured once for a scanner configuration and a tracking material. For reasonable resolutions and fields of view, the system function becomes relatively large, resulting in long acquisition times for a reasonable signal to noise ratio. However, the system function has several properties that can be used to improve the signal to noise ratio. In accordance with the present invention, spatial symmetry and / or identical responses at different frequencies are used for this purpose.
