LADP-2 Sistemụ Nnwale nke Pulsed NMR

Nkọwa dị mkpirikpi:

Pulsed Fourier na-agbanwe resonance magnetik nuklia na-eji mpaghara RF pulsed mee ihe na sistemụ nuklia iji hụ nzaghachi nke sistemu nuklia na usu, ma na-eji teknụzụ Fourier transform (FFT) ngwa ngwa iji gbanwee akara ngalaba oge ka ọ bụrụ akara ngosi ngalaba ugboro, nke bụ. Dakọtara na otutu otu ugboro na-aga n'ihu na-efegharị nuklia magnetik resonance spectrometers na-enwe obi ụtọ n'otu oge ahụ, ya mere enwere ike ịhụ ihe ngosi resonance nuklia n'ọtụtụ buru ibu, yana mgbama ahụ kwụsiri ike Ka ọ dị ugbu a, a na-eji usoro pulse na ọtụtụ spectrometers NMR, ebe A na-eji usoro pulse mee ihe na MRI.
