چکیده

Three-dimensional visualization is a new research field in information processing and VTK is a visualization toolkit with strong functions. Due to the fact that most two-dimensional microfabric models of coarse-aggregate materials are not accurate, three-dimensional model is needed. This study laid its focus on the theoretical model of three-dimensional visualization and the visualization technology based on VTK to study the coarse-aggregate morphology and the microfabric. The experimental reconstruction results show that the particle morphology and inter-particle pore space are clear and can describe the morphological features of coarse-aggregate particle accurately with the assistance of suitable virtual cutting method.

3-D computed tomography reconstruction: another tool to teach anatomy in the veterinary colleges

This letter underpins the use of three-dimensional computed tomography (3D-CT) reconstruction as an aid to teach veterinary anatomy. Cases were presented to students in order to observe normal and clinically abnormal patients. The images provided excellent details of relevant structures and could serve as a tool for teaching anatomy. Many sources describe different options to enhance anatomical...

Three-dimensional reconstruction of New Zealand rabbit antebrachium by multidetector computed tomography

The aim of this study was to reveal biometric peculiarities of New Zealand white rabbit antebrachium (radius and ulna) by means of three-dimensional (3D) reconstruction of multidetector computed tomography (MDCT) images. Under general anesthesia, the antebrachiums of a total of sixteen rabbits of both sexes were scanned with a general diagnostic MDCT. Biometric measurements of the reconstructed...

Fast System Matrix Calculation in CT Iterative Reconstruction

Introduction: Iterative reconstruction techniques provide better image quality and have the potential for reconstructions with lower imaging dose than classical methods in computed tomography (CT). However, the computational speed is major concern for these iterative techniques. The system matrix calculation during the forward- and back projection is one of the most time- cons...
