Spiculation Quantification Method Based on Edge Gradient Orienta...A new approach to quantify the lung nodule speculation levels in CT (computed tomography) images was proposed. Firstly, two-dimensional image of nodule was generated by using the spiral scan technology. Secondly, the lung nodule was segmented in the two- ...
Adaptive hp finite element method for fluorescence molecular tom... ... geometries at visible and near-infrared wavelengths. In this paper, we report an efficient numerical method for fluorescence molecular tomography (FMT) that combines the advantage of SPN model and adaptive hp finite element method (hp-FEM). For purposes ...
THE EXPERIMENTAL STUDY OF STRESS-RELATED PATHOLOGICAL CHANGES IN...In experiments on newborn rats with stress-related intracranial hemorrhage (ICH) using Doppler optical coherence tomography (DOCT) we have shown that latent stage of ICH (4 h after stress) is characterized by decrease of venous blood outflow and the loss ...
AUTOMATED EXTRACTION OF THE INNER CONTOUR OF THE ANTERIOR CHAMBE...Manual analysis of anterior segment optical coherence tomography (AS-OCT) images is fairly time consuming, and inter-observer reproducibility cannot be guaranteed. Therefore, automated analysis methods of AS-OCT images are necessary in clinical ...
MICROWAVE-INDUCED THERMOACOUSTIC IMAGING FOR EARLY BREAST CANCER...Microwave-induced thermoacoustic tomography (TAT) is a noninvasive, nonionizing modality based on the inherent differences in microwave absorption of malignant breast tissues and normal adipose-dominated breast tissues. In this paper, a TAT system based ...
INFLUENCE OF LIMITED-PROJECTION ON FLUORESCENCE MOLECULAR TOMOGR...Challenges remain in imaging fast biological processes in vivo with fluorescence molecular tomography (FMT) due to the long data acquisition time. Data acquisition with limited projections can greatly reduce the time consumption, but the influence of ...
AXIAL SUPERRESOLUTION BY PHASE FILTER IN OPTICAL COHERENCE TOMOG...Axial superresolution in optical coherence tomography (OCT) by a three-zone annular phase filter is demonstrated. In the proposed probe of a spectral domain OCT system, the width of the central lobe of the axial intensity point spread function is apodized ...
