Visualization of Plant Fibres via Diffusion Tensor Imaging
The paper deals with MR imaging of plant fibres via Diffusion weighted imaging(DWI)and Diffusion tensor imaging(DTI).Imaging plant fibres helps to better understand the process of nourishing the plants,and also to come to know the internal structure of plants without damaging them.To measure diffusion in the plant specimen,the well-known NMR method was used,currently referred to as the Pulsed field gradient spin-echo(PFGSE).Experimental measurement was conducted on an MR tomograph system with the gradient field B0 = 4.7 T.Onion and dill were used as specimens to be measured.The values obtained by the PFGSE method were used to calculate diffusion weighted images(DWI).The measurement of diffusion weighted images was performed in 6 directions of the gradients(x,y,z,xy,xz,yz)and the data obtained served to calculate the DTI image of the specimen being measured.
