ABSTRACT:
In a method and apparatus for functional imaging an impulse sequence is used in which an examination subject is charged with a readout gradient with sub-pulses of alternating polarity. By means of at least two-dimensional Fourier transformation, an image data matrix having N rows is generated from the raw data thereby acquired. After a stimulation of the subject, a second image data matrix is acquired. The coincidence of opposed signal changes that occur at two pixels disposed from each other by a distance of N/2 rows in the image matrix is checked. Found coincidences are evaluated as functional activity.
