subject

ICG Autofluorescence Fizika Hitozāns Fluorescence Difūza atstarošana

description

Maģistra darba mērķis ir izpētīt artērijas ar ICG/hitozāna plāksteri fluorescences un difūzā refleksijas intensitātes spektrus iedarbības vietās ar lāzera iedarbību un bez. Operācijām uz artērijas piemīt sava sarežģītība tādēļ, ka artērijas diametrs ir mazs, tāpēc aizšūt artērijas griezumu nav tik vienkārši. Tādēļ tika izgudrots hitozāna/ICG plāksteris, ja uz to iedarbojas ar 810 nm lāzeri, notiek plākstera adhēzija ar artēriju. Lai veiktu operāciju, ir jāizvēlas pareizā lāzera iedarbības doza uz plāksteri. Šajā nolūkā tika izpētīti autofluorescences intensitātes spektri, ICG fluorescences intensitātes spektri tuvajā infrasarkanajā diapazonā, un paraugu difūza atstarošana. Rezultātā tika konstatēts, ka autofluorescence labāk atspoguļo sakausēšana vietas ar lāzeri.
