Dosimetry and Biomedical Modeling Group

The research activities of the Dosimetry and Biomedical Modeling Group include:

  • application of the ionizing radiation in medicine, in particular optimization of radiological exposure assessment of staff and patients undergoing medical therapy and diagnosis. For this purpose the dosimetry methods based on use of termoluminescent detectors (TLD) and dedicated phantoms (static and dynamic heart phantom, dosimetry phantom) are employed,
  • mathematical modeling of selected physiological processes, especially focused on application of compartment modeling for extracorporeal liver support therapy,
  • experimental and theoretical studies on melanoma cancer photodynamic therapy as well as development of models of light, oxygen and photosensitizers transport at cellular and tissue level.
