```|>|~第 264 回 Q-NA セミナー|
|日&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;時| 2010 年 11月 18日 (木) 15:40 - 16:15|
|場&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;所| 九州大学伊都キャンパス 数理学研究院 3階 中セミナー室3|
|講&nbsp;演&nbsp;者| Pavel Strachota (Czech Technical University in Prague)|
|題&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;目| Numerical issues behind the MR-DTI visualization algorithm|
|概&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;要| For the purpose of MR-DTI data visualization, we have developed a numerical algorithm based on a mathematical model of texture diffusion. Accompanied by data preprocessing and postprocessing
procedures, this algorithm forms the cornerstone of the MEGIDDO (Medical Employment of Generating Images by Degenerate Diffusion Operator) software tool, which is briefly introduced in this contribution. Afterwards, we focus on investigating the properties of the numerical solution methods. Emphasis is put
on the assessment of several numerical schemes with respect to artificial diffusion. Both visual and quantitative methods for scheme comparison are discussed. |
