Results:

Imaging methods with orientation on porous materials using low magnetic fields. A new imaging method was developed able to detect minuscule susceptibility variations in thin biological and physical samples. The investigated samples need not contain water. Images with resolution in order of micrometers were acquired in slices of nanometer thickness.

A corresponding theory was semi-finished and significant results were achieved in the field of the basic magnetic field and RF magnetic field measurement using the sequence of Gradient-Echo.

The first experiments were performed for definition of the measuring sequences related to relaxation times measurements. Research in the field of measurements of stationary and RF magnetic fields using low-level magnetic field. A theory was semi-finished and important results were achieved in the field of the basic magnetic field and RF magnetic field measurement using the sequence of Gradient-Echo. Study of NMR imaging using magnetic liquids as a contrast medium, preparation and testing of ferro-fluids in the structure of nanoparticles. Important advance was achieved not only in preparing the magnetic liquids but also in applications on selected NMR experiments. Thin layers (botanical and physical samples) were depicted and also the study of aiming medicines using magnetic liquids continued with subsequent testing of efficiency using NMR imaging methods. Laboratory animals were tested using magnetic liquid and conditions were created for tests by hyper-gravitations using a centrifuge. Studies of magnetic susceptibility effects using magnetic resonance imaging on physical and biological samples indicated a good perspective of the research orientation.
