Parametric Method for Correction of Intensity Inhomogeneity in MRI Data

Categories:

A. Samsonov, R. Whitaker, C.R. Johnson Intensity inhomogeneity is one of the main obstacles for MRI data post processing. The problem requires retrospective correction due to the strong dependence of the inhomogeneity on patient anatomy and the accompanying acquisition protocol. We have developed a new method for correcting the inhomogeneities using a polynomial estimation of […]

SCI Institute Plays Role In Governor’s State of the State

Categories:

For four-year-old Natalie Wright, appearing in front of the state legislature might be just another exciting trip with her family. But, for Governor Mike Leavitt, Natalie represents the fundamental reason for leveraging research and technology within the state of Utah. Natalie was diagnosed with a brain tumor when she was two years old. Natalie’s neurosurgeon […]

Segmenting Tomographic Data

Categories:

Dr. Ross Whitaker and Vidya Elangovan Traditionally, processing tomographic data begins with reconstructing volumes. However, when the tomographic data is incomplete, noisy, or misregistered tomographic reconstruction can produce artifacts in the volume, which makes subsequent segmentation and visualization more difficult. Researchers in the SCI institute are developing direct methods for segmenting tomographic data. The strategy […]

Immersive Visualization: A Research Update

Categories:

J.D. Brederson and M. Ikits What is Immersive Visualization? The goal of visualization is to aid in the understanding of complex scientific data, typically using techniques from the fields of computer graphics and animation. To gain additional insight, immersive visualization places the user directly within the data space through virtual reality technology. The resulting immersive […]
