This investigation tested the hypothesis that interactive, low-resolution telemedicine is an effective method for radiologists' consultations. The case material consisted of radiographs and digital images from patients with 14 paediatric diseases rea

Our industrialized society places a premium on the ability to resolve visually fine-spatial detail in the environment. But the perceptual demands of new display systems may involve temporal acuity as much as spatial acuity. Inability to “switch”

A three-dimensional system for dosimetric calculation of radiation from interstitial brachytherapeutic implants was developed and was compared with conventional dosimetry performed with a commercial two-dimensional system. Software programs written f

The purpose of this study was to assess heterogeneity of tumor microcirculation determined by dynamic contrast-enhanced magnetic resonance (MR) imaging and its prognostic value for tumor radiosensitivity and long-term tumor control using pixel-by-pix

A contaminated binormal receiver operating characteristic (ROC) model is proposed to account for ROC data that have very few false-positive reports even though many healthy subjects are sampled. The model assumes that no signal information is capture

The authors' purpose was to evaluate how well the contaminated binormal receiver operating characteristic (ROC) model fits (a) degenerate data for which standard ROC models commonly fail and (b) nondegenerate data from exemplary experiments, for whic

Receiver operating characteristic (ROC) data with false-positive fractions of 0 are often difficult to fit with standard ROC methods and are sometimes discarded. Some extreme examples of such data were analyzed to evaluate the nature of these difficu

The authors compared the accuracies of CO2 and iodinated contrast material in the densitometric quantification of eccentric vascular stenoses.Five precision-machined eccentric phantom stenoses of 50%, 60%, 70%, 80%, and 90% cross-sectional area narro

We used two glass models of the colon to test the hypothesis that luminal septations increase efficiency of flow. Each was a straight glass tube 4 cm in diameter and filled with water. One had four septations narrowing the lumen to 2 cm; the other ha
