  1. 1. Spectroscopic techniques for photodynamic therapy dosimetry

    Author : Ann Johansson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; diffuse light spectroscopy; photodynamic therapy; biomedical optics; Atom- och molekylärfysik;

    Abstract : Photodynamic therapy (PDT) as a cancer treatment modality relies on the simultaneous presence of three components; light, photosensitiser and oxygen. Once excited by the light, the photosensitiser can interact with oxygen, leading to the formation of toxic oxygen species. READ MORE

  2. 2. Photodynamic therapy- pain and aspects of pain relief

    Author : Christina Halldin; Göteborgs universitet; []
    Keywords : actinic keratosis; field cancerization; interviews; nerve block; pain; photodynamic therapy; transcutaneous electrical nerve stimulation;

    Abstract : Photodynamic therapy – pain and aspects of pain relief Christina Halldin Department of Dermatology and Venereology, Sahlgrenska University Hospital, Institute of Clinical Sciences at the Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden ABSTRACT Photodynamic therapy (PDT) is a non-invasive treatment option for superficial basal cell carcinoma (BCC), squamous cell carcinoma (SCC) in situ or Bowen’s disease (BD), and actinic keratoses (AK). One of the advantages of PDT is the possibility to treat field cancerization. READ MORE

  4. 4. Laser diode systems for photodynamic therapy and medical diagnostics

    Author : Eva Samsöe Andersen; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quasi-phasematching; photodynamic therapy; laser-induced fluorescence; medical laser systems.; Histology; cytochemistry; histochemistry; tissue culture; Histologi; Laserteknik; Laser technology; cytokemi; histokemi; vävnadskultur; Diagnostik; Diagnostics; second harmonic generation; pulsed lasers; spatial filtering; Diode lasers; optical feedback; Fysicumarkivet A:2004:Samsöe Andersen;

    Abstract : This work concerns techniques for improvement of the coherence properties of diode lasers so that they may be used in two specific medical applications: (Interstitial) photodynamic therapy (PDT) and laser-induced fluorescence diagnostics. In the first application, spatial coherence is crucial, since the treatment light should be delivered through relatively thin optical fibers to optimize treatment and to facilitate minimally invasive treatment.
