<title>A portable device for optical assessment of the cardiovascular condition</title>

2003

A hand-held prototype device for detection and processing of the tissue-remitted optical signals has been developed and tested. The photoplethysmography (PPG) principle was applied to follow the dilation and contraction of skin blood vessels during the cardiac cycle. Cardiovascular condition of the monitored person was assessed by temporal analysis of the recorded PPG signals as well as by shape analysis of the mean single-period PPG signals.© (2003) COPYRIGHT SPIE--The International Society for Optical Engineering.

MSc course program on biomedical optics

1997

A new Msc study course program on biomedical optics has been developed and adapted. The program consists of three main parts. (1) Fundamentals of tissue optics, (2) Optical sensing for diagnostics and monitoring, (3) Laser-tissue interaction and laser treatment. The full program and some comments on it are presented.
