Non-invasive LED-based screening solution for skin cancer

2019

Skin cancer is the most common type of malignant tumors in humans. Early diagnosis is the key to successful surgical treatment. In this work we present a non-invasive screening tool for early stage detection of skin cancer and also for the evaluation of post-operative scars.

Spectral imaging as a tool for the evaluation of skin cancer post-operative scars

2020

Skin cancer is the most common type of cancer in the USA and worldwide.1 An early diagnosis is the key to a successful treatment. Among the skin cancers, the malignant melanoma (MM) accounts for 1% of the cases while it is responsible for the majority of deaths. Basal cell carcinoma (BCC) is the most common form of skin cancer with a very low mortality rate.2 Unfortunately, skin cancer recurrence is a common problem for MM and BCC patients. We propose a post-operative scar screening with non-invasive autofluorescence (AF) imaging to detect an early growth of any residual tissue from the cancer removal procedure. The screening images can serve also as a visual evidence for the post-op patien…

The application of diode laser in the treatment of oral soft tissues lesions. A literature review

2017

Background Since its appearance in the dental area, the laser has become a treatment of choice in the removal of lesions in the oral soft tissues, due to the numerous advantages they offer, being one of the most used currently the diode laser. The aim of this review was to determine the efficacy and predictability of diode laser as a treatment of soft tissue injuries compared to other surgical methods. Material and methods A literature review of articles published in PubMed/MEDLINE, Scopus and the Cochrane Library databases between 2007 and 2017 was performed. "Diode laser", "soft tissue", "oral cavity" and "oral surgery" were employed for the search strategy. Only articles published Englis…

THE APPLICATION OF NEEDLE RADIOFREQUENCY FOR THE REDUCTION OF ACNE SCARS: A CASE STUDY.

2019

Background: Acne fulminans can leaveunsightly scars that can have a detrimental effect on a person’s ability to function in society, resulting in a deterioration in the overall quality of life of these patients. Scientific research shows that problems with self-esteemmay lower a person’s quality of life, making them reluctant to interact with other people.This, in turn, may lead to depression and, in extreme cases, to suicide. For people who suffer from acne fulminans, this is an extremely serious problem.This is compounded by the fact that even if they spend much of their life fighting acne, ultimately successfully, they still may be left with the visual effects of the disease, like scars.…

Temperature measurement in gas mixtures by femtosecond Raman-induced polarization spectroscopy

2003

European Conference on Nonlinear Optical Spectroscopy (ECONOS) MAR 30-APR 01, 2003 BESANCON, FRANCE; The potential of femtosecond Raman-induced polarization spectroscopy (RIPS) for the simultaneous determination of temperature and concentrations was investigated. These measurements were related to the rotational time response of the molecular gas mixture, which was measured as a function of the pump-probe time delay. The change of the polarizability anisotropy with respect to the vibrational levels was taken into account. The results of temperature measurements in pure CO2 showed good agreement with the values obtained by a thermocouple. The RIPS technique was also applied to a CO2-N2 gas m…
