Figure 15.

Combined T₁- and T₂-weighted image of a cross section of the phantom described in the text. To obtain the image, a T2-TSE pulse sequence was used on a 3 T Philips Ingenia human MRI scanner with parameters $\mathrm{TR}=2000$ ms and $\mathrm{TE}=200$ ms, (the inversion pulse was not applied). Other parameters of the experiment were: 16-channel head coil for the radiofrequency (RF)-pulse application and detection of proton free induction decay, voxel size 0.5 × 0.5 × 10 mm³, size of image matrix 160 × 160.
