Tsarin Gwaji na LADP-2 na Pulsed NMR

Takaitaccen Bayani:

Pulsed Fourier transform nuclear magnetic resonance yana amfani da pulsed RF field don yin aiki akan tsarin nukiliya don lura da martanin tsarin nukiliya ga bugun jini, kuma yana amfani da fasahar Fourier transform (FFT) mai sauri don canza siginar yankin lokaci zuwa siginar yankin mita, wanda yayi daidai da mita ɗaya mai ci gaba da raƙuman ruwa masu yawan mita ɗaya. Ana samun motsin magnetic resonance spectrometers a lokaci guda, don haka ana iya ganin abin da ke faruwa a cikin babban kewayon, kuma siginar ta tabbata. A halin yanzu, ana amfani da hanyar bugun jini a yawancin na'urorin NMR spectrometers, yayin da ake amfani da hanyar bugun jini a cikin MRI.
