MRI IMAGE-FORMING

摘要

The invention relates to image-forming based on magnetic resonance (MRI) of a concealed object, wherein the object and its surrounding area display different relaxation properties, comprising of: applying a magnetic field, aligning magnetic spins of the object and the surrounding area; measuring T1 relaxations by disrupting the alignment with RF pulses and detecting relaxations corresponding with alignment; measuring T2 relaxations by disrupting the alignment with RF pulses and detecting relaxations transversely of the alignment; forming on the basis of the different relaxation properties of the object and its surrounding area at least one image part of the slice from each of the measurements; and performing both measurements for each image part in a predetermined sequence of the detection for a preceding respectively following image part.
