Abstract
The invention relates to a method based on the NMR phenomenon and magnetic resonance imaging techniques for the examination of an object, such as a human body, an animal or a tree trunk, wherein the image-related information is collected by effecting several times the operations required by a so-called imaging sequence, wherein the excitation procedure is followed by coupling across the object a magnetic field gradient, a so-called phase-encoding gradient, produced as a resultant of one or more divergent gradient fields, and thereafter a so-called read-out gradient during which a nuclear magnetic resonance signal is collected. One or more component gradient fields of said phase-encoding gradient produce a read-out gradient in some of the sequence repetition times.
