| Abstract | [Summary] In previous papers are described the basic and clinical studies of a method for collecting data synchronously from 2 different directions with dual scinticameras and for computerized analysis there-of. This paper describes results of a study in which 3-dimensional scientigraphy was proved to be possible by means of examining the steric expression of the cardiac blood pool as an application of this method. Data on the cardiac blood pool were synchronously collected with dual scinticameras at 30° form the right anterior oblique direction and 60° from left anterior oblique direction ; and from each gated image was constructed a 3-dimensional image as an ellipsoid of 3 revolutions of the ventricle. In other words, the major axis of the ventricle was divided into n equal parts from each image to make the sliced plane. Four points on the XY were determined from the distance between the major axis and the margin ; the quartan elliptical arc passing through these points was calculated ; and one slice was made up by connecting the arcs. A 3-dimensional image is made up by overlapping n slices, when the gradient of the XYZ direction was modified from the difference between the gradient of 2 images and the length of the major axis. The 3-dimensional image so made up well indicated the morphology of the blood pool and the gradient of the axis in the thoracic cavity, which quite unlike the conventional 2-dimentional images expressed organs sterically. This is a new image expressing method, of which much may be expected. |
