V prispevku je opisana uporaba tri-dimenzionalnega magnetno resonančnega slikanja (3D MRI) na primeru vejice hrasta doba. Tridimenzionalni MR modeli in virtualni prečni prerez vejice razkrivajo, da imajo kompleksi vazicentričnih traheid in trahej, ksilemski trakovi, stržen in tkiva v neposredni bližini kambijeve cone večji MR signal in s tem tudi večjo vlažnost kot skorja in libriformska vlakna. Prednost 3D MRI je, da pri slikanju hkrati pridobimo slike z odlično prostorsko ločljivostjo, hkrati pa tudi pripadajoče podatke o prostorski porazdelitvi vode v materialu. 3D MRI dopolnjuje druge mikroskopske tehnike v lesarski znanosti.

Abstract

Application of three dimensional magnetic resonance imaging (3D MRI) for imaging of pedunculate oak is demonstrated in this contribution. Three-dimensional volume rendered MR images and virtual cross section showed that complexes of vasicentric tracheids and vessels, xylem rays and tissues adjacent to cambial zone had higher MR signal and hence higher water content than bark and libriform fibers. Advantage of 3D MRI is in that with a single scan, high resolution images and information on moisture content can be obtained. MRI complements other forms of microscopy in wood science.
