To analyze brightness, contrast, and color balance of digital versus film retinal images in a multicenter clinical trial, to propose model image from exemplars, optimize both types for evaluation age-related macular degeneration (AMD).The Age-Related Eye Disease Study 2 (AREDS2) is enrolling subjects 90 clinics, with three quarters them using one quarter cameras. Image brightness (B), contrast (C), (CB) were measured three-color luminance histograms. First, the exemplars (film digital)...
Purpose To develop EdgeSelect, a semi-automatic method for the segmentation of retinal layers in spectral domain optical coherence tomography images, and to compare results with manual method. Methods SD-OCT (Heidelberg Spectralis) scans 28 eyes (24 patients diabetic macular edema 4 normal subjects) were imported into customized MATLAB application, manually segmented by three graders at corresponding inner limiting membrane (ILM), segment/ellipsoid interface (ISe), retinal/retinal pigment...
Purpose To evaluate the safety and efficacy of performing histotripsy through overlying gas-filled bowel in an ex vivo swine model.
Purpose Intra‐procedural monitoring and post‐procedural follow‐up is necessary for a successful ablation treatment. An imaging technique which can assess the geometry accurately beneficial to monitor evaluate In this study, we developed an automated segmentation serial low‐dose, noisy computed tomography (CT) or contrast‐enhanced CT (CECT). Methods Low‐dose, temporal CECT volumes were acquired during microwave on normal porcine liver (four with non‐contrast eight CECT). Highly constrained...
This paper describes the theoretical basis and practical implementation of PARSEC, a knowledge-based system that uses probabilistic case based reasoning. PARSEC is major component in PANDA surveillance system, developed under DARPA leadership to support maritime situation awareness monitoring on global scale. detects unusual vessel motions (deviations) learned normalcy models then flags those particular deviations an analyst likely describe as remarkable or suspicious, given available...
Background The USee device is a new self-refraction tool that allows users to determine their own refractive error. We evaluated the ease of use in adults, and compared error correction achieved with clinical manifest refraction. Methods Sixty adults uncorrected visual acuity <20/30 spherical equivalent between –6.00 +6.00 diopters completed refraction self-refraction. Results Subjects had mean (±SD) age 53.1 (±18.6) years, 27 (45.0%) were male. Mean measured by –0.90 D (±2.53) –1.22...
Different surgical methods for epiphysiodesis of limb length discrepancy (LLD) have been described. Although these are variably effective, they associated with morbidity (pain and limp) potential complications. Microwave ablation is a less-invasive opportunity to halt growth by selectively destroying the plate via thermal energy treat LLD in children.
