20.500.12556/RUL-138448 Raziskava zgradbe lesa s tri-dimenzionalnim magnetno resonančnim slikanjem Research of wood structure by three dimensional magnetic resonance imaging 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. 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. jederska magnetna resonanca les vlažnost lesa hrast nuclear magnetic resonance wood moisture content oak true false true Slovenski jezik Angleški jezik Članek v reviji 2022-07-21 08:05:01 2022-07-21 08:05:02 2022-09-15 04:16:46 0000-00-00 00:00:00 2008 0 0 Str. 7-11 št. 1 Let. 60 2008 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2008-01-01 543.429.23:630*811 0024-1067 1616777 RAZ_Oven_Primoz_2008.pdf RAZ_Oven_Primoz_2008.pdf 1 9B34E29AAF145CA44452488B3F55B6A8 2aa9db4c911613797f2ee6bb643dd0b371b2fd48d86aae61273a306ea5b95df0 7871b598-08bb-11ed-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=158781 Biotehniška fakulteta Les 0 0 0
