Abstract
A method for colon screening and collecting data by using Magnetic Particle Imaging wherein an imaging magnetic field is generated with a spatial distribution of the magnetic field strength such that the area of examination in the colon consists of a first sub-area with lower magnetic field strength, where the magnetization of a magnetic particle which was pre-delivered to the colon is not saturated, and a second sub-area with a higher magnetic field strength, where the magnetization of said magnetic particle is saturated. The spatial location of both sub-areas in the area of examination is modified so that the magnetization of said particles changes locally. Signals are acquired and are evaluated to obtain information about the spatial distribution of the signals in the area of examination. The method may be carried out during an entire peristaltic cycle in a colon portion or segment.
