Název v původním jazyce

Testing the quality of magnetic gradient fields for studying self-diffusion processes by magnetic resonance methods

Popis výsledku v původním jazyce

Imaging techniques based on the principle of nuclear magnetic resonance (NMR) rank with the most advanced methods for studying chemical and biological properties of substances. Their universality makes them particularly suited for use in a wide range ofscientific branches. NMR has found significant application in medicine. The diffusion effects of water molecules in tissues reduce the magnitude of spin echo in NMR measuring methods. Based on the amplitude change in the image, the diffusion coefficientss and their distribution in the specimen being measured can be calculated. MR images of an object weighted by diffusion coefficients require a defined sequence of gradient pulses and an accurate knowledge of their time behaviour. Methods for measuring the diffusion coefficients require the knowledge of the minimum length of leading and trailing edges, the defined magnitude of the magnetic field gradient being excited, and also the symmetry of positive and negative gradient pulses (the ze
