Abstract
Due to minimal absorption and scattering, light at select wavelengths in the short wavelength infrared (SWIR: 1000–2500 nm) region can be utilized for non-invasive, deep tissue imaging. These select wavelength regions, known as the SWIR windows, occur between 1200 and 1350 nm (second window), 1600 and 1870 nm (third), and 2100 and 2350 nm (fourth). The SWIR windows can penetrate deeply into tissue, revealing important information, such as collagen content. It is believed that osteoarthritis (OA), the most common form of arthritis, is due to the loss of proteoglycans and degradation of collagen—the main components of articular cartilage. In this paper, we review the SWIR windows for the detection and assessment of OA, an irreversible degenerative joint disease, based on changes in cartilage. With the use of longer SWIR wavelengths and artificial intelligence, the SWIR windows could open up new applications in the field of OA and bone diseases.
期刊介绍：
The first international journal dedicated to publishing reviews and original articles from this exciting field, the Journal of Biophotonics covers the broad range of research on interactions between light and biological material. The journal offers a platform where the physicist communicates with the biologist and where the clinical practitioner learns about the latest tools for the diagnosis of diseases. As such, the journal is highly interdisciplinary, publishing cutting edge research in the fields of life sciences, medicine, physics, chemistry, and engineering. The coverage extends from fundamental research to specific developments, while also including the latest applications.
