NMR BLOOD FLOW IMAGING IN CAROTID ARTERIES

这项工作的目的是验证和实施一种新方法 用于创建颈动脉的定量血流图像 核磁共振 (NMR) 成像和称为核磁共振 (NMR) 的现象 均匀回波重定相。 均匀回波重相位已被证明发生在那些 自旋基团沿磁场梯度流动时的情况。 该技术将使用连续和校准进行验证和校准 脉动流模型和实验动物。 表面线圈将 设计和制造以补充流动成像技术 优化颈动脉的信噪比和空间分辨率 图像。

The purpose of this proposed work is to validate and implement a new method for creating quantitative blood flow images of the carotid arteries using Nuclear Magnetic Resonance (NMR) Imaging and the NMR phenomenon called even-echo rephasing. Even-echo rephasing has been shown to occur in those circumastances when spin groups flow along magnetic field gradient. The technique will be validated and calibrated using continuous and pusatile flow phantoms and in experimental animals. Surface coils will be designed and fabricated to complemented the flow imaging technique by optimizing signal-to-noise and spatial resolution in the carotid artery images.
