The United States Department of Veterans Affairs was an early adopter of a standardized approach to incorporating visible light images into the electronic medical record [7]. Increasingly, visible light imaging is being deployed beyond individual departments, as part of a trend referred to as Enterprise Imaging [ 8 ] .
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which in artificial narrowband form has a number of proven negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related ...
Medical optical imaging is the use of light as an investigational imaging technique for medical applications, pioneered by American Physical Chemist Britton Chance. Examples include optical microscopy , spectroscopy , endoscopy , scanning laser ophthalmoscopy , laser Doppler imaging , optical coherence tomography , and transdermal optical imaging .
Photomedicine is an interdisciplinary branch of medicine that involves the study and application of light with respect to health and disease. [1] [2] Photomedicine may be related to the practice of various fields of medicine including dermatology, surgery, interventional radiology, optical diagnostics, cardiology, circadian rhythm sleep disorders and oncology.
Medical imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues . Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease.
Rox Anderson proposed the medical application of the free-electron laser in melting fats without harming the overlying skin. [42] At infrared wavelengths , water in tissue was heated by the laser, but at wavelengths corresponding to 915, 1210 and 1720 nm , subsurface lipids were differentially heated more strongly than water.
Spectral imaging may use the infrared, the visible spectrum, the ultraviolet, x-rays, or some combination of the above. It may include the acquisition of image data in visible and non-visible bands simultaneously, illumination from outside the visible range, or the use of optical filters to capture a specific spectral range. It is also possible ...
The major applications of synchrotron light are in condensed matter physics, materials science, biology and medicine. A large fraction of experiments using synchrotron light involve probing the structure of matter from the sub-nanometer level of electronic structure to the micrometer and millimeter levels important in medical imaging.
