Abstract
Sposób polega na uzyskaniu projekcji w metodzie obrazowania Elektronowym Rezonansem Paramagnetycznym z wykorzystaniem metody detekcji prostej oraz zmiany zewnętrznego pola magnetycznego. Podczas oddziaływania na umieszczoną w rezonatorze próbkę wieloskładnikowym polem magnetycznym ustala się, za pomocą niskoszumowego przedwzmacniacza o dużej dynamice i wzmocnieniu oraz przetwornika (ADC) cyfrową postać sygnału EPR, zarejestrowanego w warunkach przemiatania w obecności gradientu pola magnetycznego, a następnie projekcję jako zbiór sygnałów korzystnie absorpcyjnych lub dyspersyjnych dla określonego zakresu chwilowych wartości pola magnetycznego lub ich harmonicznych, otrzymanych korzystnie za pomocą sumowania lub uśredniania wartości sygnału EPR dla korzystnie jednakowych wartości chwilowych wartości pola magnetycznego. Do realizacji powyższego sposobu służy układ zawierający urządzenie sterujące, sterownik (2), generator wysokiej częstotliwości (3), wzmacniacz mocy(4), mostek (5), przedwzmacniacz wysokiej częstotliwości(6), modulator (7), przetwornik (ADC), pamięć, generator niskiej częstotliwości, obwód rezonansowy, cewki skanujące, cewki II modulacji, cewki gradientu Gx, cewki gradientu Gy, cewki gradientu Gz, cewki pola głównego, zespół wzmacniaczy mocy.The method consists in obtaining projection in the method of electron paramagnetic resonance imaging using a method of simple detection and change of the external magnetic field. When interacting with a multi-component magnetic field placed in a resonator, the digital dynamic EPR signal is determined by means of a low-noise preamplifier with high dynamics and amplification, as well as a converter (ADC) recorded under sweeping conditions in the presence of a magnetic field gradient, followed by projection as a set of preferably absorption signals or dispersion for a specific range of instantaneous magnetic field values or their harmonics, obtained preferably by adding or averaging the EPR signal values for preferably equal instantaneous magnetic field values. To implement the above method, a system containing a control device, controller (2), high frequency generator (3), power amplifier (4), bridge (5), high frequency preamplifier (6), modulator (7), converter (ADC) is used, memory, low frequency generator, resonant circuit, scanning coils, modulation coils II, Gx gradient coils, Gy gradient coils, Gz gradient coils, main field coils, power amplifiers.
