Pulsed Fourier inoshandura yenyukireya magineti resonance inoshandisa pulsed RF munda kuti iite pane yenyukireya system kuona mhinduro yenyukireya kune iyo pulse, uye inoshandisa nekukurumidza Fourier shandura (FFT) tekinoroji kushandura iyo nguva domain chiratidzo mu frequency domain chiratidzo, chinova zvakaenzana neakawanda frequency frequency inoenderera yenyukireya magnetic resonance spectrometers vanofara panguva imwe chete, saka iyo nyukireya magnetic resonance phenomenon inogona kucherechedzwa munzvimbo yakakura, uye chiratidzo chakatsiga Parizvino, nzira yekushambadzira inoshandiswa munzvimbo zhinji dzeNMR, nepo kupomba nzira inoshandiswa muMRI.

Kuedza

1. Nzwisisa yakakosha panyama dzidziso uye yekuyedza kumisikidza kwePNMR system. Dzidza kutsanangura zvinoitika zvinoenderana nemuviri muPNMR uchishandisa yechinyakare vector modhi.

2. Dzidza kushandisa zviratidzo zve spin echo (SE) uye yemahara induction kuora (FID) kuyera T₂(spin-spin yekuzorora nguva). Ongorora simba remagineti homogeneity pane chiratidzo cheNMR.

3. Dzidza kuyera T₁ (spin-lattice nguva yekuzorora) uchishandisa reverse kupora.

4. Inonzwisisika nzwisisa iyo yekuzorora mashandiro, cherekedza mhedzisiro yeparamagnetic ions panguva yenyukireya yekuzorora nguva

5. Kuyera T₂yemhangura sulphate mhinduro pazvikamu zvakasiyana Sarudza hukama hwaT₂ pamwe nekuchinja kwekufungisisa.

6. Edzai chiyero chemakemikari kufambiswa kwemuenzaniso.
