Observer variation in ophthalmology.
Data collected by clinicians and nurses from patients with clinically diagnosed lens opacities revealed that there was poor repeatability of the description of the position of lens opacities, statistically significant observer variation in determining visual acuity, and good repeatability as to what visual tasks the patient can perform. It is suggested that clinicans should give more weight to ...
متن کاملIntra- and Inter-Observer Reproducibility of Ultrasound Measurements of Pelvic Inlet Diameter in Pregnant Women
Objectives: To determine intraand inter-observer reproducibility of the ultrasound measurement of pelvic inlet in the first trimester of pregnancy. Methods: Transabdominal pelvic ultrasound was performed to measure the pelvic inlet anteroposterior diameter using a 2D probe in twelve Chinese women having a singleton pregnancy. Scans were performed in the first trimester by three sonographers. Th...
متن کاملInter-Observer Variation in Ultrasound Measurement of the Volume and Diameter of Thyroid Nodules
OBJECTIVE Thyroid nodule measurement using ultrasonography (US) is widely performed in various clinical scenarios. The purpose of this study was to evaluate inter-observer variation in US measurement of the volume and maximum diameter of thyroid nodules. MATERIALS AND METHODS This retrospective study included 73 consecutive patients with 85 well-defined thyroid nodules greater than 1 cm in th...
متن کاملObjective vs Observer Measurements
Post-inflationary boundary conditions are essential to the existence of our highly structured universe, and these can only come about through quantum mechanical state reductions – i.e., through measurements. The choice is between: An ‘objective’ measurement that allows reduction to occur independent of conscious observers, and an ‘observer’ based measurement that ties reduction to the existence...
متن کاملDiameter-Constrained Steiner Tree
Given an edge-weighted undirected graph G = (V,E, c, w), where each edge e ∈ E has a cost c(e) and a weight w(e), a set S ⊆ V of terminals and a positive constant D0, we seek a minimum cost Steiner tree where all terminals appear as leaves and its diameter is bounded by D0. Note that the diameter of a tree represents the maximum weight of path connecting two different leaves in the tree. Such p...
