Medical Imaging
Optical Coherence Tomography
Optical Coherence Tomography (OCT) is an optical signal acquisition and processing method. It can capture micrometer resolution creates three dimensional and cross sectional images of biological structures using differences in the reflection of light and help for the visualisation of minute details in both two and three dimensionally.
OCT is an established medical dental imaging technique. It is widely used in various fields such as:
A) Medical Science:
a)to obtain high-resolution images of the retina and the anterior segment of the eye
b)to image coronary arteries in order to detect vulnerable lipid-rich plaques
B) Dental Science:
a)to acquire images of incipient carious lesions as well as advanced carious lesions for diagnosis, prevention and treatment of dental caries
b) to evaluate the different disease of oral mucosa
c) to determine the micro leakage of dental restorations and endodontic fillings
d)to identify the dental implant status sometimes
e)to determine the integrity of dental prosthesis, their quality and their marginal fitting
f)OCT is also used in orthodontic treatment, for example, for determining tooth movement under light orthodontic forces.
