    Method de imagine lacteal\u0103 a particulelor magnetice<\/h2>\n

    This nanoparticulele, from also, has a tehnici devoltator of imagine lactating noi. O imagine care al\u0103pteaz\u0103 a particulei magnetice (MPI) este o etnie relativ\u0103 c\u0103reia nu \u00eei pas\u0103 s\u0103 detecteze luminoaza nanoparticulelor de feroxid. Capabil de sensibilitate nanomolar\u0103, or define a imaginii care confer\u0103 independent\u0103 ad\u00e2ncimii \u0219i or you use the gall de str\u0103lucitoare pe c\u00e1 de sigur\u0103 \u0219i stabil\u0103, dear poate fi urm\u0103rit\u0103 pentru S\u0102PT\u0102M\u00c2NI. MPI difer\u0103 de la tehnici fine la imagistic\u0103 medical\u0103, deoarece imaginabilis a ie\u0219it luminos doar \u00een originalul sunt, comparativ cu RMN \u0219i ultrasunete.<\/p>\n

    \u00cen ciuda acestor avantaje, MPI are the definition for combining tehnicile RMN sau CT. Define spa\u021bial\u0103 MPI depinde de satura\u021bia nanoparticulelor, pentru a selecta sarea proprietar\u0103 magnetice ale cadrului.

MPI acest pre\u021b cel mai competitiv se compar\u0103 cu medicamentul tradi\u021bional de imagistic\u0103 lactal\u0103.<\/p>\n

    Ce vechi set\u0103ri pot helps Nanoparticulele define it as imaginii?<\/h2>\n

    Nanoparticulele aplic\u0103 diverse tipuri de tehnologie de infantilistic\u0103 imagistic\u0103 pentru microscop, inclusiv microscop electronic de scanare. De exemplu, sau corela\u021bie imagistic\u0103 digital\u0103 (DIC) to fost combine with or electronic microscope of exploitation for non-scale suprafe\u021be. Cu toate acestea, DIC deoarece to work it specific\u0103 ca suprafe\u021be material ale teru a random contrast test model, izotrop \u0219i dou\u0103 stropi mari.
