Abstract
Przedmiotem zgłoszenia jest sposób uzyskiwania obrazów wysokiej rozdzielczości z przestrzeni odwrotnej w obrazowaniu rezonansu magnetycznego oraz układ do stosowania tego sposobu. Sposób według zgłoszenia polegający na pomiarze sygnału EPR podczas oddziaływania na umieszczoną w rezonatorze próbkę wieloskładnikowym polem magnetycznym. Poszczególne punkty w przestrzeni wektora falowego k uzyskuje się według następujących kroków: rejestruje się sygnały rezonansu magnetycznego podczas skanowania próbki w obecności szybkozmiennej modulacji pola magnetycznego i w obecności zmiennego gradientu pola magnetycznego, przestrzeń wektora k wypełnia się z sygnałów rezonansu magnetycznego dla wybranego czasu τ, których pozycje w przestrzeni k wyznacza się na podstawie chwilowych wartości gradientu pola magnetycznego występującego w trakcie detekcji każdego z sygnałów rezonansu magnetycznego, a następnie aproksymuje się do określonych położeń w przestrzeni k, po czym w znany sposób wykonuje się rekonstrukcję obrazów przestrzennych, a następnie w znany sposób na podstawie obrazów zrekonstruowanym z różnym τ otrzymuje się obrazy czasu relaksacji (T2*).The subject of the application is a method for obtaining high resolution images from reciprocal space in magnetic resonance imaging and a system for using the method. The method according to the application consisting in measuring the EPR signal while influencing the sample placed in the resonator with a multicomponent magnetic field. Individual points in the wave vector space k are obtained according to the following steps: magnetic resonance signals are recorded when scanning the sample in the presence of fast-varying magnetic field modulation and in the presence of a variable magnetic field gradient, the vector space k is filled from the magnetic resonance signals for the selected time τ, whose positions in the k-space is determined on the basis of the instantaneous values of the magnetic field gradient occurring during the detection of each of the magnetic resonance signals, and then approximated to specific positions in the k-space, after which the reconstruction of spatial images is performed in a known manner, and then in a known manner on on the basis of the images reconstructed with different τ, the images of the relaxation time (T2 *) are obtained.
