Use of MR Tomography in Studying Biological Tissues

Popis výsledku v původním jazyce

The technique of MRI can be used to determine the number of hydrogen nuclei in biological tissues. The intensity of an image weighted by spin density is proportionate to the number of proton nuclei in the chosen slice, and the MR image is the mapping oftheir distribution in biological tissues. In the paper, an image acquisition method is proposed and the procedure of processing the calibration MR images and images of biological tissues being measured is given with the aim of suppressing as much as possible the effects of image noise and low sensitivity of MR measurement on the accuracy of the parameters obtained. The subject of measurement was the dependence of the number of proton nuclei of early somatic spruce embryos and the magnitude of diffusionconstants on the embryo growth time. For the study of the assimilation characteristics of plants the total surface of spruce needles was calculated on the basis of the circumference and shape of their radial slices.
