Triple Spectral Line Imaging of Whole-Body Human Skin: Equipment, Image Processing, and Clinical Data
Autor: Janis Spigulis, Uldis Rubins, Edgars Kviesis-Kipge, Inga Saknite, Ilze Oshina, Egija Vasilisina
Publikováno v: Sensors, Vol 24, Iss 22, p 7348 (2024)
Multispectral imaging can provide objective quantitative data on various clinical pathologies, e.g., abnormal content of bio-substances in human skin. Performance of diagnostics increases with decreased spectral bandwidths of imaging; from this point

Spectral Line Reflectance and Fluorescence Imaging Device for Skin Diagnostics
Autor: Janis Spigulis, Zigmars Rupenheits, Uldis Rubins, Madars Mileiko, Ilze Oshina
Publikováno v: Applied Sciences, Vol 10, Iss 21, p 7472 (2020)
The multi-spectral-line imaging concept, which was recently implemented for the snapshot mapping of three main skin chromophores—melanin, oxy-hemoglobin, and deoxy-hemoglobin, is further explored for the snapshot capturing of four spectral line ima

Comparison of a near-infrared reflectance spectroscopy system and skin conductance measurements for in vivo estimation of skin hydration: a clinical study
Autor: Inga Saknite, Aleksejs Zavorins, Ilona Zablocka, Janis Kisis, Janis Spigulis
Publikováno v: Journal of Biomedical Photonics & Engineering, Vol 3, Iss 1 (2017)
Diffuse reflectance spectroscopy system was developed for estimation of skin hydration in the near-infrared spectral range of 900-1700 nm. Experimental setup consisted of a near-infrared spectrometer, Y-type fiber optics probe with 1 detection and 6

Time of flight for photon in human skin
Autor: Antra Dzerve, Inesa Ferulova, Alexey Lihachev, Janis Spigulis
Publikováno v: Journal of Biomedical Photonics & Engineering, Vol 2, Iss 3 (2016)
The time of flight for photons in human skin was measured using picosecond diode laser. Two different wavelength lasers were used - 405 nm and 510 nm. A difference for time of flight in normal skin and in nevus was observed as well as a difference fo

Three-dimensional representation of triple spectral line imaging data as an option for noncontact skin diagnostics
Autor: Ilze, Ošina, Janis, Spigulis, Ilona, Kuzmina, Laura, Dambite, Anna, Berzina
Publikováno v: Journal of Biomedical Optics. 27
Skin malformations in dermatology are mostly evaluated subjectively, based on a doctor's experience and visual perception; an option for objective quantitative skin assessment is camera-based spectrally selective diagnostics. Multispectral imaging is
