1. What is a Handheld Optical Coherence Tomography Scanner for Primary Care Diagnostics?

A handheld optical coherence tomography (OCT) scanner for primary care diagnostics is a portable imaging device that uses light waves to capture high-resolution, real-time, three-dimensional images of tissue microstructure. This allows healthcare providers to visualize subsurface structures non-invasively, aiding in early disease detection and monitoring, according to research published in the Journal of Biomedical Optics.

Optical coherence tomography (OCT) is a non-invasive imaging technique similar to ultrasound, but instead of sound waves, it uses light waves to create high-resolution images of tissue microstructure. OCT measures the intensity and time-of-flight information of backscattered light to reconstruct three-dimensional reflectivity maps up to several millimeters deep within the tissue. This technology has found applications in ophthalmology, cardiology, dermatology, otolaryngology, gastroenterology, oncology, and dentistry, as reported by the National Institutes of Health (NIH).

1.1 How Does Handheld OCT Work?

Handheld OCT scanners function by emitting near-infrared light into the tissue and analyzing the reflected light to create detailed cross-sectional images. The scanner measures the intensity and time delay of the reflected light, which is then used to generate high-resolution images of the tissue structure. This allows physicians to visualize subsurface structures, such as retinal layers, skin layers, and the tympanic membrane, in real-time.
