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 ] .
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.
Areas of application are life science, medicine, agriculture, and environmental science. Similar to the differentiation between " electric " and " electronics ," a difference can be made between applications such as therapy and surgery , which use light mainly to transfer energy, and applications such as diagnostics , which use light to excite ...
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 .
[9] [3] Photomultiplier tubes have been used to measure biophoton emissions from fish eggs, [10] and some applications have measured biophotons from animals and humans. [ 11 ] [ 12 ] [ 13 ] Electron Multiplying CCD (EM-CCD) optimized for the detection of ultraweak light [ 14 ] have also been used to detect the bioluminescence produced by yeast ...
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.
Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, neonatal jaundice, and skin wound infections.
Broadband polychromatic light (white light) and LED radiation can only penetrate 0.0017 mm to 5 mm of tissue. [24] For example, research shows that at wavelengths of 450 nm and 650 nm only 1% of the light reaches approximately 1.6 mm and very little reaches 5 mm. [ 25 ] [ 26 ] Only laser radiation can propagate into deeper tissues.
