An Efficient Method of Volume Rendering for Medical Slices
نویسندگان
چکیده
We present an efficient method for volume rendering. This method uses a special light source slit-light source to illuminate the volume and simulates the interactions of light with objects, such as light absorption, scattering and reflection. In comparison with previous methods, our method has several advantages. This includes flexibility for implementation, efficiency for computation, high reality for display and easiness of parallelization. The algorithm can be parallelized easily either using the Data Space Subdivision method or the Image Space Subdivision method.

Segmentation Assisted Object Distinction for Direct Volume Rendering
Ray Casting is a direct volume rendering technique for visualizing 3D arrays of sampled data. It has vital applications in medical and biological imaging. Nevertheless, it is inherently open to cluttered classification results. It suffers from overlapping transfer function values and lacks a sufficiently powerful voxel parsing mechanism for object distinction. In this work, we are proposing an ...
متن کاملInteractive Radial Volume Histogram Stacks for Visualization of Kidneys from CT and MRI
Optical parameter assignment via Transfer Functions (TF) is the sole interactive part in medical visualization via volume rendering. Being an interactive element of the rendering pipeline, TF specification has very important effects on the quality of volume-rendered medical images. However, TF specification should be supported by informative search spaces, interactive data exploration tools and...
متن کاملA method for interactive manipulation and animation of volumetric data
We outline an efficient method for visualizing and manipulating volumetric data, in particular, cardiac MRI data sets. The approach is designed to allow interactive manipulation and real-time animation of volumetric data sets. The underlying model provides an efficient graphical representation for interactive rendering while not eliminating data from the volume of interest. We believe this mode...
متن کاملBrain Volume Estimation Enhancement by Morphological Image Processing Tools
Background: Volume estimation of brain is important for many neurological applications. It is necessary in measuring brain growth and changes in brain in normal/abnormal patients. Thus, accurate brain volume measurement is very important. Magnetic resonance imaging (MRI) is the method of choice for volume quantification due to excellent levels of image resolution and between-tissue contrast. St...
متن کاملLocal Transparency Control of Medical Slice Images and its Application to Slice-Slice and Slice-Volume Fusion
In medical visualization, 2D slice images of human volume data are important as well as 3D volume rendering. The slice images are advantageous in focusing on regions of interest, while the volume rendering enables us to easily observe the whole region. In this paper, we propose a method to (1) create a transparent slice image, where its opacity is controllable by a user-defined transfer functio...
