Abstract: |
Medical techniques based upon optical imaging technologies are important tools in clinical practice. The use of optical imaging in medical diagnosis is well established, and a large array of techniques are in current use, such as white light endoscopy, autofluorescence imaging, and optical coherence tomography. The applications of these techniques are expanding, and newer imaging technologies are becoming available to address problems and limitations associated with existing methods. Beyond diagnostics, optical imaging is increasingly a useful component of interventional medical procedures, such as image-guided surgery. In procedures such as surgical tumor resection, fluorescence imaging can aid surgeons in improving both accuracy and completeness of removal. Relevant to both diagnostic and therapeutic applications, Cerenkov luminescence imaging is a potential clinical technique which relies upon generation of visible-spectrum light by beta particles in a dielectric medium; this method could allow for coupling of a multimodal optical component to existing molecular imaging techniques, such as positron emission tomography, and also provide a means of monitoring distribution of administered clinically relevant radionuclides such as lutetium-177. © 2019, Springer Nature Switzerland AG. |
