Abstract
Uređaji za magnetsku rezonanciju snimaju signale koji potiču iz jezgri vodika (protona), a koje se nalaze u molekulama ljudskog tijela na način da je to tijelo postavljeno u snažno, homogeno magnetsko polje. Uklanjanje šuma u slikama dobivenim pomoću magnetske rezonance, prikazali smo kroz postupak učitavanja originalne slike, dodavajući šum i uklanjajući šum sa tri različita filtera, mjenjajući im parametre. Korišteni filteri su: medijan filter, Wienerov filter i filter s pomičnom sredinom.
Keywordsmagnetic resonance noise average filter median filter Wiener filter.

Parallel abstract (English)
Magnetic resonance imaging devices record signals emitted by hydrogne nuclei (protons) in the molecules of the human body. It is achieved by positioning thebody inside a strong, homogenous magnetic field. Removing noise in magnetic resonance images are presented through the process of downloading the original image, adding noise and eliminating noise with three different filters, changing their parameters. The used filters are: median filter, Wiener filter and average filter.
