    Sammanfattning : The name Upconverting nanoparticles refers to a novel category of luminescence emitters that are capable of generating visible luminescence upon excitation with noncoherent and longer wavelength monochromatic near-infrared light, at excitation fluence rates as low as 1-103 W/cm2. This unique optical behaviour is of great interest to researchers as it could potentially allow for virtually autofluorescence free luminescence imaging of living tissue. LÄS MER

  3. 2. Performance Assessment of Cerenkov Emission Imaging

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen; Lunds universitet/Medicinsk strålningsfysik, Lund

    Författare :Emma Mellhammar; [2013]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Laddade partiklar med hög energi kan ibland färdas snabbare än ljusets hastighet i det medium det för stunden befinner sig i. När detta sker, emitteras så kallat Cerenkovljus. Ljuset ligger inom det synliga spektret och kan alltså detekteras med vanlig kamerateknik. LÄS MER
