Resolution enhancement with improved range Doppler algorithm in ... ... Doppler algorithm is proposed to abate the trade-off between resolutions and depth of focus in spectral domain optical coherence tomography. By considering the finite beam width and the shape of the wavefronts produced by the Gaussian beam, a physical ...
3-D Adaptive Sparsity Based Image Compression with Applications ... 3-D Adaptive Sparsity Based Image Compression with Applications to Optical Coherence Tomography
A hybrid metal artifact reduction algorithm for x-ray CT Purpose: Presence of metal artifacts is a major reason of degradation of computed tomography image quality and there is still no standard solution to this issue. A class of recently investigated metal artifact reduction (MAR) methods based on forward ...
Using OCT image to distinguish human acupoint from non-acupoint ... Using the optical coherence tomography (OCT) images, the optical attenuation coefficients (\mu t) of human Laogong acupoint and non-acupoint tissues are measured after empty irradiation and 808-nm 100-mW irradiation for 10 min in vivo non-invasively. The ...
Detection of subsurface defects of fused silica optics by confoc... A non-destructive technique for subsurface measurements is proposed by combining light scattering method with laser confocal scanning tomography. The depth and distribution of subsurface defect layers are represented in term of scattered light intensity ...
High-resolution subsurface articular cartilage imaging based on ... We demonstrate the subsurface imaging of an articular cartilage using Fourier-domain common-path optical coherence tomography. The bare fiber probe integrated with a hypodermic needle provides the rigidness required to perform lateral scanning with less ...
All-fiber ring-cavity based frequency swept laser source for fre... We develop a high-speed tunable, quasi-continuous-wave laser source for frequency domain (FD) optical coherence tomography (OCT). The laser resonance is realized within a unidirectional all-fiber ring cavity consisting of a fiber coupler, two fiber ...
An efficient Jacobian scaling method for time-domain optical mam... Time-domain diffuse optical tomography can efficiently reconstruct optical parameters which can be further applied in diagnosing early breast cancer. Nevertheless, the performances of reconstructed imaging are badly influenced by different Jacobian ...
A marker-free automatic alignment method based on scale-invarian... In electron tomography, alignment accuracy is critical for high-resolution reconstruction. However, the automatic alignment of a tilt series without fiducial markers remains a challenge. Here, we propose a new alignment method based on Scale-Invariant ...
Experimental validation for time-domain fluorescence diffuse opt... We present a full three-dimensional, featured-data algorithm for time-domain fluorescence diffuse optical tomography that inverts the Laplace-transformed time-domain coupled diffusion equations and employs a pair of appropriate transform-factors to ...
