A method is developed to show that instead of using data from the entire spectrum, only selected spectral bands are required to improve image reconstruction accuracy in spectral diffuse optical tomography. ©2007 Optical Society of America OCIS codes: (100.3190) Inverse problems; (170.3660) Light propagation in tissues;

Developing diffuse optical tomography methods for neuroimaging of humans is challenging due geometry and light level constraints. Analysis of multi-distant high-density imaging arrays shows the feasibility of imaging up to 20 mm depth within the adult brain. ©2008 Optical Society of America OCIS codes: (170.6960) Tomography; (170.2655) Functional monitoring and imaging; (330.4270) Vision system...

For diffuse optical tomography reconstruction, DC-based method outperforms frequency-domain method in background artifacts, at the known cost of increased coupling between absorption and scattering. The differences of these methods diminish when spatial priors are available. ©2010 Optical Society of America OCIS codes: (170.3880) Medical and biological imaging; (170.3010) Image reconstruction t...

We have developed optical coherence tomography system with KTN optical probe for a diagnosis in the orthopedic surgery fields. The present system demonstrates that biological image was measured by using KTN optical scanner for having degree of freedom in sample arm as optical coherence tomography. In addition, the developed optical coherence tomography (OCT) system has shown feasibility for ima...

This review paper describes the applications of dental optical coherence tomography (OCT) in oral tissue images, caries, periodontal disease and oral cancer. The background of OCT, including basic theory, system setup, light sources, spatial resolution and system limitations, is provided. The comparisons between OCT and other clinical oral diagnostic methods are also discussed.

A review is presented of different scanning, acquisition and processing techniques used to obtain depth-resolved information in optical-coherence tomography (OCT). The principles and performances of different OCT techniques are discussed and images from different types of tissue are presented. Special attention is devoted to the progress in using the time-domain flying spot OCT technique and co...

33 Volume images of the body are an indispensable clinical diagnostic tool. For visualizing and examining complex body organs such as the brain, doctors depend on the information 3D imaging modalities, such as x-ray computed tomography (CT) and magnetic resonance imaging (MRI), provide. Although these mature techniques have developed into reliable systems delivering high-quality images, some dr...

In this Letter, we demonstrate high resolution, three-dimensional optical imaging of in vivo blood vessel networks using speckle variance optical coherence tomography, and the quantification of these images through the development of biologically relevant metrics using image processing and segmentation techniques. Extracted three-dimensional metrics include vascular density, vessel tortuosity, ...

Optical coherence tomography angiography (OCTA) is a noninvasive approach that can visualize blood vessels down to the capillary level. With the advent of high-speed OCT and efficient algorithms, practical OCTA of ocular circulation is now available to ophthalmologists. Clinical investigations that used OCTA have increased exponentially in the past few years. This review will cover the history ...
