Errors Involved in Radiological Heart Volume Determination by the Ellipsoid-approximation Technique.
The radiological measurement of the heart's volume during life has been attempted by model-making (Palmieri, 1929), tomographic (Fuchs and Bayer, 1953), and simple formula techniques. The latter depend upon the assumption that the shape of the heart approximates to that of some regular figure, estimates of its volume then being obtainable from measurements of the heart's shadows in orthodiagrap...
متن کاملClinical Experience with Radiological Determination of Heart Volume.
Since the basic studies of Rohrer (1916) and Kahlstorf (1932), much work on ellipsoid approximation techniques for cardiac volume estimation has been done in Sweden. Publications such as those of Jonsell (1939), Kjellberg, Lonroth, and Rudhe (1951), and Maurea, Nylin, and Sollberger (1955) bear testimony to the careful and critical way in which the many problems concerned have been tackled. As ...
متن کاملThe Minimum Volume Ellipsoid Metric
We propose an unsupervised “local learning” algorithm for learning a metric in the input space. Geometrically, for a given query point, the algorithm finds the minimum volume ellipsoid (MVE) covering its neighborhood which characterizes the correlations and variances of its neighborhood variables. Algebraically, the algorithm maximizes the determinant of the local covariance matrix which amount...

Brain Tumor Growth and Volume Detection by Ellipsoid-Diameter Technique Using MRI Data
Magnetic resonance (MR) images are a very useful tool to detect the tumor growth in brain but precise brain image segmentation is a difficult and time consuming process. Manual segmentation of brain tumors from MR images is a challenging and time consuming task. In this paper our approach has been discussed to detect the volume of brain tumor cells using ellipsoid-Diameter and graph based metho...
