  1. 11. Preclinical X-ray imaging beyond attenuation contrast

    Författare :Kian Shaker; Hans Hertz; Anna Burvall; Bert Müller; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysik; Physics; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : Medical imaging is a cornerstone of modern clinical practice. Here, X-ray imaging is the given choice for rapid morphological imaging with excellent spatial resolution, albeit with sensitivity often insufficient for resolving subtle pathological changes to soft tissues.

  3. 12. Time-Resolved Spectroscopy for Pharmaceutical Applications

    Författare :Christoffer Abrahamsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elektromagnetism; optik; Near-infrared spectroscopy; Time-resolved spectroscopy; Pharmaceutical analysis; Multivariate data analysis; Electromagnetism; Light transport in turbid media; Photon migration; akustik; acoustics; optics;

    Sammanfattning : The work presented in this thesis aims at improving spectroscopic techniques for analysis of pharmaceutical solids. This improvement is achieved by the combining and development of instrumentations and data evaluation tools from two research fields: the fields of near infrared spectroscopy and biomedical optics.

  4. 13. Fabrication and characterization of periodically poled KTB and RB-doped KTB for applications in the visible and UV

    Författare :Shunhua Wang; Fredrik Laurell; Peter Smith; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nonlinear optics; second-harmonic generation; quasi-phasematching; type-I QPM SHG; type-II QPM SHG; KTP; RKTP; periodic electric-field poling; Physics; Fysik;

    Sammanfattning : This thesis deals with the fabrication and the characterization of periodically-poled crystals for use in lasers to generate visible and UV radiation by second-harmonic generation (SHG) through quasi-phasematching (QPM). Such lasers are of practical importance in many applications like high-density optical storage, biomedical instrumentation, colour printing, and for laser displays. LÄS MER

  5. 14. Autonomous Lab-on-a-chip: solutions and fast prototyping tools

    Författare :German Comina Bellido; Daniel Filippini; Edwin Jager; Anke Suska; Niels B. Larsen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous Lab-on-a-chip; bio-chemical sensing; sensor fabrication; biosensing cell phone; 3D printed fluidics; 3D printed optics.;

    Sammanfattning : In this thesis, solutions for the development of autonomous Lab-on-a-chip (LOC), and 3D printing for fast prototyping of LOC devices are investigated. Lab-on-a-chip devices integrate analytical systems and conditioning processes in a compact package. LÄS MER
