Abstract

Det beskrives en metode og et system for ikke-invasiv kvantitering av vevsperfusjon som oppnås ved en destruksjon-reperfusjonsprosess som gir et signal som er representativt for lokal middelkonsentrasjon under reperfusjon, ved å derivere minst en lokal vevsperfusjonsverdi. Systemet omfatter midler for å justere eller relatere en funksjon av tiden med S-form karakteristika til signalet som er proporsjonalt med lokalmiddelkonsentrasjon under reperfusjon og så å foreta en korrespondanse mellom minst en verdi av minst en parameter av funksjonen med S-form karakteristika med minst en lokal vevsperfusjonsverdi (som midlere hastighet, midlere transitt-tid, midlere strøm, perfusjonsvolum) eller en attributt (som blodstrømningsmønster, strømningsfordelingsvarians eller skjevhet).
