時域磁振造影術

Time-Domain Magnetic Resonance Imaging

指導教授 : 江簡富

摘要


在本篇論文中,我們提出了一個全新的「時域磁振造影術」架構。相較於現行之「頻域磁振造影」,該架構簡化了梯度磁場的複雜度(只需一個梯度磁場),並大幅減少成像所需時間。   「時域」與「頻域」磁振造影術的主要差異在於處理磁振信號上的不同,我們利用電腦模擬來比較兩種架構間的優缺點。

並列摘要


A time-domain magnetic resonance imaging (MRI) technique is proposed to reconstruct the image of sample slice with one set of gradient coils only. Working principles are thoroughly analyzed and compared with conventional Fourier-based techniques to explore their pros and cons. Simulations are conducted to assess the plausibility of this technique for practical use.
