Skin effects and UV dosimetry of climate therapy in patients with psoriasis
Bartosova, Veronika (Master thesis, 2010)Sun exposure and climate therapy is an effective treatment for psoriasis. However, even though this treatment gives the patients relief from their discomforting symptoms, it has some potentially dangerous side effects such ... -
Spectral diagnostics and characterization of atopic dermatitis in children's health - A Hyperspectral Imaging System using an Acousto-Optic Tunable Filter
Liland, Morten Sikle (Master thesis, 2017)Hyperspectral imaging with high spectral and spatial resolution can be used to analyse material using spectroscopic methods. This technique can be applied to human tissue as a general purpose diagnostics tool and as an aid ... -
Støyreduksjon av hyperspektrale bilder
Fjerdingen, Sverre (Master thesis, 2010)Støyreduksjon har blitt utført på hyperspektrale bilder i både spektral retning og romlige retninger. Algoritmene som har blitt benyttet for å oppnå støyreduksjon er Principal Component Analysis (PCA), Maximum Noise Fraction ... -
Suitability of diffusion approximation for an inverse analysis of diffuse reflectance spectra from human skin in vivo
Naglic, Peter; Vidovic, Luka; Milanic, Matija; Randeberg, Lise Lyngsnes; Majaron, Boris (Journal article; Peer reviewed, 2019)Diffusion approximation (DA) of the radiative transport equation allows derivation of enclosed solutions for diffuse reflectance from multi-layer scattering structures, such as human skin. Although the DA is known to be ... -
Tissue responses to hexyl 5-aminolevulinate-induced photodynamic treatment in syngeneic orthotopic rat bladder cancer model: possible pathways of action
Arum, Carl-Jørgen; Gederaas, Odrun Arna; Larsen, Eivind La Puebla; Randeberg, Lise Lyngsnes; Hjelde, Astrid; Krokan, Hans Einar; Svaasand, Lars O.; Chen, Duan; Zhao, Chun-Mei (Journal article; Peer reviewed, 2011)Orthotopic bladder cancer model in rats mimics human bladder cancer with respect to urothelial tumorigenesis and progression. Utilizing this model at pT1 (superficial stage), we analyze the tissue responses to hexyl ... -
Towards automated sorting of Atlantic cod (Gadus morhua) roe, milt, and liver - Spectral characterization and classification using visible and near-infrared hyperspectral imaging
Paluchowski, Lukasz A.; Misimi, Ekrem; Grimsmo, Leif; Randeberg, Lise Lyngsnes (Journal article; Peer reviewed, 2016)Technological solutions regarding automated sorting of food according to their quality parameters are of great interest to food industry. In this regard, automated sorting of fish rest raw materials remains as one of the ... -
Towards real-time medical diagnostics using hyperspectral imaging technology
Bjorgan, Asgeir; Randeberg, Lise Lyngsnes (Journal article; Peer reviewed, 2015)Hyperspectral imaging provides non-contact, high resolution spectral images which has a substantial diagnostic potential. This can be used for e.g. diagnosis and early detection of arthritis in finger joints. Processing ... -
Vessel contrast enhancement in hyperspectral images
Bjorgan, Asgeir; Denstedt, Martin Anders Fredrik; Milanic, Matija; Paluchowski, Lukasz A.; Randeberg, Lise Lyngsnes (Journal article; Peer reviewed, 2015)Imaging of vessel structures can be useful for investigation of endothelial function, angiogenesis and hyper-vascularization. This can be challenging for hyperspectral tissue imaging due to photon scattering and absorption ... -

Wavelet based feature extraction and visualization in hyperspectral tissue characterization
Denstedt, Martin Anders Fredrik; Bjorgan, Asgeir; Milanic, Matija; Randeberg, Lise Lyngsnes (Journal article; Peer reviewed, 2014)Hyperspectral images of tissue contain extensive and complex information relevant for clinical applications. In this work, wavelet decomposition is explored for feature extraction from such data. Wavelet methods are simple ...
