  • Method to determine electron relaxation times, T1, in EPR tomography
    Patent number: 9110146
    Abstract: A method for determination of the images of electron relaxation times, T1, in EPR tomography consists in the resultant relaxation time, T1, established from the ratio of amplitudes of signals recorded for various scanning directions is found, whereupon a variability function of the resultant relaxation time, T1, is found for at least two different scan frequencies, whereupon projections for the respective relaxation times are established for every point of the recorded spectra by matching functions specific for the respective relaxation times to the resultant function of variability of relaxation time, and then images are reconstructed in 1D or in 2D or in 3D depend of the experimental conditions.
    Type: Grant
    Filed: March 22, 2012
    Date of Patent: August 18, 2015
    Assignee: POLITECHNIKA POZNANSKA
    Inventors: Tomasz Czechowski, Mikolaj Baranowski, Kazimierz Jurga, Jan Jurga, Wojciech Chlewicki, Piotr Szczepanik, Piotr Kedzia
