Research subjects:

Our activities are interdisciplinary and cover the full path from the idea and development of a theoretical physical description through its hardware and algorithmic implementation and culminate in testing on an animal model and on healthy volunteers and patients in a clinical setting. 

Selected examples of applications of ongoing research activities:

  • Non-invasive, optical devices based on near-infrared spectroscopy technique for the diagnosis of strokes, intracranial bleeding, intraoperative monitoring of cerebral oxygenation (e.g. carotid artery clog removal), detection of brain death, etc.. 
  • Non-invasive imaging of cerebral cortex activity during movement or viewing of visual stimuli, also under oxygen deprivation or high g-force overload conditions.
  • Non-invasive monitoring of muscle oxygenation during exercise.
  • Non-contact, non-invasive monitoring of wound healing using the correlative speckle field imaging technique.
  • Non-invasive monitoring of cerebral flow by diffuse correlation spectroscopy technique.
  • Optical measurement of systolic and diastolic blood pressure.
  • Tools for modelling light propagation in tissues that, when applied to a measurement method, allow for recovery of information on the oxygenation or blood supply of the tissue, e.g. “Parallel, multi-purpose Monte Carlo code for simulation of light propagation in segmented tissues” (https://github.com/swojtkiewicz/mc_cuda_ompi) or “Two-layered blood-lipid phantom and method to determine absorption and oxygenation employing changes in moments of DTOFs” (https://github.com/asudakou/Analyzing_TD-NIRS).

Research field description:

The Biomedical Optics Laboratory carries out research work in the field of medical diagnostic techniques based on phenomena related to the interaction of near-infrared light with tissues. In particular, these include measurement methods of haemodynamic parameters of tissues based on near-infrared spectroscopy and dynamic light scattering on red blood cells.
