Study of blood vessels reaction to local heating by imaging photoplethysmography

Научно-технический вестник информационных технологий, механики и оптики
The possibility of using a new contactless method of imaging photoplethysmography to assess thermoregulatory vasodilatation of blood vessels was studied. Perfusion reaction in a region of the outer forearm in response to local heating up to 41 ± 1 °C was
