PURPOSE To demonstrate the application of high-resolution spectral-domain optical coherence tomography (SD-OCT) for three-dimensional (3D) retinal imaging of small animals and quantitative retinal information extraction using 3D segmentation of the OCT images. METHODS A high-resolution SD-OCT system was built for in vivo imaging of rodent retina. OCT(More)
Optical Doppler tomography (ODT) is a branch of optical coherence tomography (OCT) that can measure the speed of a blood flow by measuring the Doppler shift impinged on the probing sample light by the moving blood cells. However, the measured speed of blood flow is a function of the Doppler angle, which needs to be determined in order to calculate the(More)
Tubulin isotype distribution may play a role in the development of anti-cancer anti-tubulin drug resistance as well as in drug efficacy and specificity. Stepwise selection was used to establish non-small cell lung carcinoma (NSCLC) H460 cells resistant to combretastatin A-4 (CA4), paclitaxel or vinblastine. The results demonstrated that the rate of CA4 drug(More)
In the video analysis domain, automatic detection of actions performed in a recorded video represents an important scientific and industrial challenge. This paper presents a new method to approximate the boundaries of actions performed by a person while interacting with his environment (such as moving objects). This method relies on a Codebook quantization(More)
