Optical imaging refers to a technology that holds great potential to improve the mode of treatment, disease diagnosis, and prevention in the hospital operating room. This technology offers a host of benefits compared to radiological imaging techniques. Optical imaging technique makes use of non-ionizing radiation and reduces the patient?s radiation exposure, which gives way to numerous studies over time. It also helps differentiate soft tissues from native soft tissues or the tissues that posses exogenous or endogenous contrast media using various photon absorption profiles at different wavelengths. Optical imaging is a highly responsive imaging technique which can be used by easily combining it with other imaging techniques.
