High-resolution real-time tomography of scattering tissues is important for many areas of medicine and biology1-6. However, the compromise between transverse resolution and depth-of-field in addition to low sensitivity deep in tissue continue to impede progress towards cellular-level volumetric tomography. Computed imaging has the potential to solve these long-standing limitations. Interferomet...
Interferometric Synthetic Aperture Microscopy (ISAM) obviates the trade-off between depth-of-focus and resolution in interferometric coherence imaging. In this work, ISAM’s quantitative image reconstruction techniques are applied in a vectorial setting, thus admitting polarization-sensitive imaging. ©2007 Optical Society of America OCIS codes: (100.3190) Inverse Problems; (100.6890) Three-dimen...
BACKGROUND Methods for obtaining real-time in vivo histologic resolution by means of noninvasive endoscopic optical imaging would be a major advance for thoracic surgical diagnostics and treatment. Optical coherence tomography is a rapidly evolving technology based on near-infrared interferometry that might provide these capabilities. The purpose of this study is to investigate the feasibility ...
Understanding the etiology and evolution of the vulnerable coronary plaque is important for the early detection, treatment, and prevention of coronary artery disease. Intravascular optical coherence tomography (OCT) enables imaging of the coronary arteries in vivo with sufficient resolution to accurately differentiate arterial pathology, however, the clinical utility of this technology has been...
Photothermal diffusion-wave imaging is a promising technique for the analysis of a range of media. However, traditional diffusion-wave techniques are limited by the physics of parabolic diffusion and can only produce depth-integrated planar images. Here, we report a depth-resolved photothermal imaging modality, henceforth termed truncated-correlation photothermal coherence tomography (TC-PCT). ...
