OBJECTIVE To assess the clinical feasibility and the accuracy of two pragmatic methods in comparison with a conventional computer based method of measurement of masses from CT. METHODS Nineteen CT scans of 11 patients with severe head injury, showing 34 traumatic lesions, were examined. The volume of every lesion was digitally measured, then a panel of three examiners independently repeated t...

The ellipsoid body, a doughnut-shaped part of the fly brain, is essential for visual working memory. Gaseous second messengers establish a functional ellipsoid body and act as a short-term aid in orientation behavior.

Sonographic images of the gallbladder enable satisfactory approximation of gallbladder volume using the sum-of-cylinders method. The sum-of-cylinder measurements, however, are moderately cumbersome and time consuming to perform. In this investigation, in vitro and in vivo testing was done to determine that a simple ellipsoid method applied to sonographic gallbladder images yields reasonable vol...

This paper applies a method known in the engineering literature as Effective Independence Distribution (EID) to an approximation of the minimum volume ellipsoid, a high breakdown robust estimator of multivariate location and scale. The calculation of the minimum volume ellipsoid is an extremely computationally intensive task. Previous methods for approximating the MVE have focused on bootstrap-...

First post-Newtonian (1PN) hydrostatic equations for an irrotational fluid which have been recently derived are solved for an incompressible star. The 1PN configurations are expressed as a deformation of the Newtonian irrotational Riemann ellipsoid using Lagrangian displacement vectors introduced by Chandrasekhar. For the 1PN solutions, we also calculate the luminosity of gravitational waves in...

PURPOSE To evaluate the patterns of tumor shape and to compare tumor volume derived from simple diameter-based ellipsoid measurement with that derived from tracing the entire tumor contour using region of interest (ROI)-based 3D volumetry with respect to the prediction outcome in cervical cancer patients treated with concurrent chemotherapy and radiotherapy. MATERIALS AND METHODS Magnetic res...

A theory is proposed that combines the most basic features of conformal solution theory and scaled particle theory (SPT) . The treatment in essence provides a means for evaluating mixture properties from pure fluid data; however, two intermediate substances-the “infinitely polydisperse” (IP) mixture and the “one-and-a-half fluid”-are used to implement the mapping. Associated with the IP mixture...
