15 صفحه اولInteractive three-dimensional volume rendering of spiral CT data: current applications in the thorax.
Spiral computed tomographic (CT) data sets coupled with a real-time volume-rendering technique allow creation of accurate three-dimensional (3D) images that can be used for a wide range of clinical applications. The image contrast of and relative pixel attenuations in the final image can be interactively modified by the user in real time by manipulating trapezoidal transfer functions. Although ...
متن کاملThree-dimensional volume rendering of spiral CT data: theory and method.
Three-dimensional (3D) medical images of computed tomographic (CT) data sets can be generated with a variety of computer algorithms. The three most commonly used techniques are shaded surface display, maximum intensity projection, and, more recently, 3D volume rendering. Implementation of 3D volume rendering involves volume data management, which relates to operations including acquisition, res...
متن کاملMITRAL STENOSIS COMPLICATED BY RENAL ARTERY EMBOLISM
Six patients with mitral stenosis complicated by renal artery embolism studied prospectively are presented. In five patients there was unilateral and in one patient bilateral renal artery involvement. The diagnosis was confirmed by intravenous pyelography, retrograde pyelography, renal angiography, renal scan or a combination of these. All had atrial fibrillation, proteinuria and elevated ...
متن کاملComparison of three different techniques in parotid gland tumors using three dimensional conformal radiation therapy
Introduction: Background: Radiotherapy of parotid tumors is achieved by different radiotherapy techniques. So they deliver the dose to organs at risk such as contralateral parotid, temporal lobe & spinal cord. The consequences of high dose to OARs are xerostomia, Temporal lobe necrosis and loss of hearing. Purpose: The aim of this study was to compare different treatment tech...
