  • Acceleration of optical coherence tomography signal processing b... A multi-GPU system designed for high-speed, real-time signal processing of optical coherence tomography (OCT) is described herein. For the OCT data sampled in linear wave numbers, the maximum processing rates reached 2.95 MHz for 1024-OCT and 1.96 MHz for ...
  • Virtual-OCT: A simulated optical coherence tomography instrument We report the virtual instrumentation of both time-domain (TD) and spectral-domain (SD) optical coherence tomography (OCT) systems. With a virtual partial coherence source from either a simulated or measured spectrum, the OCT signals of both A-scan and B- ...
  • X-ray computed tomography of adhesive wicking into carbon foam ... together. In order to assess the extent and quantity of adhesive wicking into porous foam, micro X-ray computed tomography (CT) and image processing software have been utilized. Two different laser target configurations have been assessed in situ and ...
  • Optical coherence tomography imaging of cranial meninges post br... We report a new application of optical coherence tomography (OCT) to investigate the cranial meninges in an animal model of brain injury in vivo. The injury is induced in a mouse due to skull thinning, in which the repeated and excessive drilling exerts ...
  • Investigation of self-adaptive algebraic tomography for gas reco... We develop a self-adaptive algebraic tomography algorithm (SAATA) to investigate the simultaneous reconstruction of concentration and temperature distributions in larger temperature range from two views. The simplified optical arrangement with fewer ...
  • Compressive sampling photoacoustic tomography based on edge expa... ... sampling and image reconstruction method, called compressive sampling PA tomography (CSPAT), is recently proposed to make low sampling rate and high-resolution PA tomography possible. A key problem within the CSPAT framework is the design of ...
  • Terahertz imaging based on optical coherence tomography [Invited... Three-dimensional (3D) terahertz (THz) imaging or THz tomography has recently proven to be useful for nondestructive testing of ... techniques such as THz pulsed/continuous-wave radar and THz computed tomography, we propose a THz optical coherence tomography ...
  • Image reconstruction method for laminar optical tomography with ... Laminar optical tomography (LOT) is a new mesoscopic functional optical imaging technique. Currently, the forward problem of LOT image reconstruction is generally solved on the basis of Monte-Carlo (MC) methods. However, considering the nonlinear nature ...
  • Pseudo-global tomography for local micro-computed tomography wit... The computed tomography imaging of a local region inside a sample with a size larger than the field of view is particularly important for synchrotron X-ray imaging. In this letter, an improved algorithm is proposed to reconstruct the local structure ...
  • Phase retrieval for hard X-ray computed tomography of samples wi... X-ray tomography of samples containing both weakly and strongly absorbing materials are necessary in material and biomedical ... duality (PAD) method, the propagation-based phase-contrast computed tomography (PPCT) of a sample with hybrid compositions of both ...
