Optical imaging
Optical Imaging
Optical imaging (pronunciation: /ˈɒptɪkəl ˈɪmɪdʒɪŋ/) is a technique used to visually represent the interior of a body for clinical analysis and medical intervention.
Etymology
The term "optical imaging" is derived from the Greek word "optikos," meaning "of sight," and the Latin word "imago," meaning "picture" or "image."
Definition
Optical imaging involves the use of light as an investigational tool for therapeutic and diagnostic purposes. It is a non-invasive process that creates high-resolution images of the interior of the body, including the cells and molecular processes.
Types of Optical Imaging
There are several types of optical imaging techniques, including:
- Optical coherence tomography: This technique uses light waves to take cross-section pictures of the retina.
- Photoacoustic imaging: This technique combines ultrasound and laser-induced multispectral photoacoustic signals to create images.
- Diffuse optical imaging: This technique uses near-infrared light to generate images of the body.
- Optical microscopy: This technique uses visible light and a system of lenses to magnify images of small samples.
