描述(由申请人提供):本提案致力于开发和评价基于使用q空间中的径向轨迹的新型扩散光谱成像(DSI)采样方案。我们的初步数据表明,这样的计划导致更准确的取向分布函数和更快的数据采集时间。的 数据获取时间的潜在改进是显著的,并且可以导致数据获取时间短至5分钟。如此短的数据采集时间应该有助于在临床环境中使用和验证基于DSI的纤维束成像算法。
英文摘要
DESCRIPTION (provided by applicant): This proposal is devoted to the development and evaluation of novel diffusion spectrum imaging (DSI) sampling schemes based on the use of radial trajectories in q-space. Our preliminary data demonstrate that such schemes lead to more accurate depictions of the orientation distribution function and faster data acquisition times. The potential improvements in data acquisition time are significant and could lead to data acquisition times as short as 5 minutes. Such short data acquisition times should be instrumental in allowing the use and validation of DSI-based tractography algorithms in a clinical setting.
