Obtaining projections with the electron paramagnetic resonance imaging method using the analysis of multiple harmonics and the procedure application system, comprising measurement of the EPR signal during impact on the sample in the resonator with the multi-component magnetic field, is characterised in that the projection is obtained in the following steps: determination of harmonics of the EPR signals, determination of the k-th derivative of the EPR absorption signal, determination of final, not overmodulated form of projection through inverse Fourier transform of projection P k obtained through the analysis of n harmonics; performance of deconvolution of inverse Fourier transform of the projection P k through the analysis of n harmonics. To implement the method described above the system is used equipped with: master control device (1), microprocessor control system (2), high-frequency generator (3), amplifier (4), bridge (5), resonator (6), high-frequency pre-amplifier (7), detector (8), filters of the fir
