Abstract
We demonstrate that non-rigid deformations of, e.g., the mouth introduce bias in the vNav-based detection of brain motion, which causes artifacts. We present real-time brain extraction for vNavs and show that these artifacts can be removed by brain-masked registration.
摘要
我们证明，例如嘴巴的非刚性变形会在基于vNav的脑运动检测中引入偏差，从而导致伪影。我们展示了针对vNav的实时脑提取，并表明这些伪影可以通过脑掩码配准来消除。
