Abstract
Optical Tomography (OT) is a form of computed tomography using a digital model of the volume of an object by reconstructing an image of the light transmitted and scattered by the object. OT is used mostly as a form of research in medical imaging. OT depends on the reference object being at least partially light transmitting or translucent, so it works best on soft tissue, such as breast and brain tissue. Optical Coherence Tomography (OCT) is a new technology for performing high-resolution cross-sectional imaging. OCT is similar to ultrasound imaging, but uses different types of light instead of sound. OCT can provide cross-sectional images of tissue structure on the micrometer scale and in real time. OCT serves as a kind of optical biopsy and is used as a medical diagnostic imaging technology because, unlike conventional histopathology, it does not require the removal and processing of tissue specimens for microscopic examination. The study was carried out to see how the two types of optical imaging and the use of concepts and components used in the system. The light source is used to show different levels of penetration and resolution for both methods is used. The use of an interferometer in optical imaging applications is discussed along with examples of commonly used methods. The optical imaging method contributes significantly to the diversity of tomography systems. � 2015 Penerbit UTM Press. All rights reserved.
