Lihlahisoa tsa Product

Pulsed Fourier e fetola matla a khoheli a nyutlelie a sebelisa tšimo ea RF ho sebetsa ka sistimi ea nyutlelie ho bona karabelo ea sistimi ea nyutlelie ho pulse, mme e sebelisa theknoloji ea Fastier transform (FFT) ho fetola lets'oao la domain name hore e be lets'oao la maqhubu a nako, e leng e lekanang le makhetlo a mangata a sa khaotseng a maqhubu a matla a khoheli a nyutlelie a thabile ka nako e le 'ngoe, ka hona, ts'ebetso ea matla a nyutlelie e ka bonoa ka bongata,' me lets'oao le tsitsitse Hajoale, mokhoa oa pulse o sebelisoa ho li-spectrometer tse ngata tsa NMR, ha pulse method e sebelisoa ho MRI.

Liteko

1. Utloisisa khopolo ea mantlha ea 'mele le phetolo ea liteko tsa sistimi ea PNMR. Ithute ho hlalosa liketsahalo tse amanang le tsona ho PNMR u sebelisa mofuta oa khale oa vector.

2. Ithute ho sebelisa matšoao a spin echo (SE) le ho bola ha induction mahala (FID) ho lekanya T₂(nako ea phomolo ea spin-spin). Hlahloba tšusumetso ea matla a khoheli a homogeneity ho lets'oao la NMR.

3. Ithute ho metha T₁ (nako ea boikhathollo ea spin-lattice) u sebelisa mokhoa oa ho hlaphoheloa.

4. Ka mokhoa o utloisisehang mochini oa boikhathollo, sheba phello ea li-ion tsa paramagnetic nakong ea boikhathollo ba nyutlelie.

5. Lekanya T₂ea tharollo ea sulfate ea koporo libakeng tse fapaneng. Etsa qeto ea kamano ea T₂ ka phetoho ea mohopolo.

6. Lekanya phetoho e amanang ea lik'hemik'hale ea sampole.
