Light source with homogeneity of light field, primarily for induction and monitoring of photodynamic effect in vitro
Photodynamic therapy (PDT) is besides chemotherapy, radiotherapy and immunotherapy other option for treatment of tumor diseases. It is a kind of photochemotherapy that is characterized by a harmful effect of photodynamically active drug and light in the presence of oxygen molecules. The physical principle of PDT is energy or electron transfer from
TECHNOLOGY (INVENTION) DESCRIPTION:
The invention is in an arrangement of a light source with homogeneity of light fi eld, primarily for induction and monitoring of photodynamic effect in vitro, intended primarily for treatment tumor diseases via photodynamic therapy.
ADVANTAGES OVER EXISTING SOLUTIONS:
Light source with homogeneity of light fi eld, primarily for induction and monitoring of photodynamic effect in vitro consists of a body adapted for sample placing and a set of LED diodes. LEDs are mounted inside of the body and arranged in a circle around the sample minimally in one horizontal plane so that their light beams are focused on the sample. LED diodes are exchangeable.
DEVELOPMENT STATUS (STAGE):
Prototype. Validation protocols.
