Performance of isotropic light dosimetry probes based on scattering bulbs in turbid media
Autor: Johannes P. A. Marijnissen, W. M. Star
Publikováno v: Physics in Medicine and Biology. 47:2049-2058
In a previous paper the calibration of an isotropic light detector in clear media was described and validated. However, in most applications the detector is used to measure light distribution in turbid (scattering) media, that is, in tissues or tissu

Publikováno v: Oral Oncology-European Journal of Cancer Part B, 36, 286-293. Pergamon Press Ltd.
The performance of an artificial neural network was evaluated as an alternative classification technique of autofluorescence spectra of oral leukoplakia, which may reflect the grade of tissue dysplasia. Twenty-two visible lesions of 21 patients suffe

Photofrin-mediated photodynamic therapy of rat palatal mucosa: Normal tissue effects and light dosimetry

Photodynamic therapy (PDT) is a treatment modality with potential application for premalignant lesions and squamous cell carcinoma of the oral mucosa. PDT in principle has dual selectivity. This may result from a 'preferential' retention of the photo

Calibration of isotropic light dosimetry probes based on scattering bulbs in clear media
Autor: W. M. Star, Johannes P. A. Marijnissen

Miniature light detectors with isotropic response (isotropic light dosimetry probes) permit quantitative measurement of light energy fluence rates in turbid media such as biological tissues. These isotropic probes are, for example, applied in photody

Publikováno v: British Journal of Cancer
In this study the kinetics and localisation of protoporphyrin IX (PpIX) fluorescence in skin and skin tumours were examined after topically (20% for 4h) or systemically (200 mg/kg,i.p.) administered 5-aminolaevulinic acid (ALA). As a model we used ha

Publikováno v: British Journal of Cancer
Zinc(II) phthalocyanine, a hydrophobic photosensitiser, was incorporated in unilamellar liposomes and studied in vivo for fluorescence kinetics and photodynamic activity. An observation chamber mounted in a dorsal skinfold of female WAG/Rij rats was
