Method for determining the concentration of radicals projection by scanning the magnetic field in spatial-spectral imaging of EPR and a system for its application

摘要

the subject of the invention is the designation of projection concentrations radicals with scanning magnetic field in the imaging przestrzenno - epr spectral and arrangement to its application,with application in imaging of different relaxation times radical concentrations.designation of projection concentrations radicals with scanning magnetic field in the imaging przestrzenno - epr spectral range.polegajacy measuring sinogramu imaging przestrzenno - with constant amplitude spectral skanowanego magnetic field is thatduring oddzialywania on placed in the resonator with a sample wieloskladnikowym magnetic field sets up epr signals, registered in terms przemiatania,in the presence of a momentary value of gradient magnetic field, which makes up scaling to obtain sinogramu, then image przestrzenno - spectral 2d or 3d or 4d.arrangement for determining projection concentrations radicals with scanning magnetic field in the imaging przestrzenno - epr spectral, containing source signal, at least one resonator, bridgethe field coils zewnetrznego together with power supply, and the gradient field coils scanning with shape wave generators, and the detekcyjny and sterujacy is characterized by thewith the source of radio frequency signal (1) is now docked to the front of the bridge detection signal (2), which is a two way street entrances / exits przylaczony resonator (4),while the gate bridge detection signal (2) is now docked to the computer (3), in turn one with out a computer (3) is now docked to the first wave shape generator (5),that is to przylaczony coils skanujacych (6), on the one hand, the second solution computer (3), is now docked to the second wave shape generator (8), which przylaczony is to gradientowych coils (10),the third computer (3) is out now docked to a power supply (7) coils, the magnetic field (9).
