Photoplethysmography for the Assessment of Haemorheology [PDF]
Scientific Reports, 2017 AbstractHaemorheology has been long identified as an early biomarker of a wide range of diseases, especially cardiovascular diseases. This study investigates for the first time the suitability of Photoplethysmography (PPG) as a non-invasive diagnostic method for haemorheological changes.

Feasibility of Imaging Photoplethysmography [PDF]
2008 International Conference on BioMedical Engineering and Informatics, 2008 Contact and spot measurement have limited the application of photoplethysmography (PPG), thus an imaging PPG system comprising a digital CMOS camera and three wavelength light-emitting diodes (LEDs) is developed to detect the blood perfusion in tissue.

The Way to my Heart is through Contrastive Learning: Remote Photoplethysmography from Unlabelled Video [PDF]
IEEE International Conference on Computer Vision, 2021 The ability to reliably estimate physiological signals from video is a powerful tool in low-cost, pre-clinical health monitoring. In this work we propose a new approach to remote photoplethysmography (rPPG)–the measurement of blood volume changes from ...
