[The role of Fourier transformation in MR imaging and its relation to artefacts]

WALTER Norbert, VANDULEK Csaba, ARADI Mihály, BÁGYI Péter, BOGNER Péter

[Fourier transformation has become known in the field of medical imaging following the introduction of MR imaging; currently it is still probably one of the most difficult areas of MR image formation to conceive. However, Fourier transformation and K-space concept is indispensable for the understanding of most artefacts as well as the operation of fast/ultrafast MR pulse sequences. The lines of K-space represent different spatial frequency information applying to the whole image, as well as... tovább »
