Diffuse Optical Imaging (DOI)
Diffuse optical imaging (DOI) is an imaging technique that uses infrared or near-infrared light to form images of biological tissues. DOI can be used to noninvasively detect biological changes in oxygen concentration, hemoglobin, and various metabolites. It is particularly useful for imaging brain function due to its ability to measure oxygen absorption, which provides information on blood flow and neuron activity. DOI is also used in oncology, helping to diagnose and monitor the status of tumors. This imaging technique offers the potential for early detection of a variety of diseases, allowing for early intervention and improved patient outcomes. DOI is becoming an increasingly important tool in medical diagnosis and tissue imaging, as it is radiation-free, cost-effective, and easy to use.
