Local 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...
متن کاملSlice Sampling
Markov chain sampling methods that automatically adapt to characteristics of the distribution being sampled can be constructed by exploiting the principle that one can sample from a distribution by sampling uniformly from the region under the plot of its density function. A Markov chain that converges to this uniform distribution can be constructed by alternating uniform sampling in the vertica...
متن کاملDual-polarity slice-GRAPPA for concurrent ghost correction and slice separation in simultaneous multi-slice EPI.
PURPOSE A ghost correction strategy for Simultaneous Multi-Slice (SMS) EPI methods that provides improved ghosting artifact reduction compared to conventional methods is presented. Conventional Nyquist ghost correction methods for SMS-EPI rely on navigator data that contain phase errors from all slices in the simultaneously acquired slice-group. These navigator data may contain spatially nonlin...
متن کاملSlice-by-slice motion correction in spinal cord fMRI: SliceCorr
Introduction Subject motion in functional magnetic resonance imaging (fMRI) is highly problematic for the detection of responses showing small effect size and/or spatially extent. To mitigate this problem, various methods have been proposed to correct this type of motion a posteriori. These methods correct each volume using a 3D rigid-body matrix having six parameters for translation and rotati...
متن کاملImplementation of an Automatic Slice-to-Slice Registration Tool
This paper outlines the basic steps in the design and implementation of a feature based Transmission Electron Microscopy (TEM) image registration application and highlights some of the implementation details, such as the detection of features, feature descriptor design, robust filtering of mismatched descriptors, and transform estimation. Although the approach chosen is based on the Scale Invar...
