Fri, 03/13/2015 - 12:57middleping各位老师好，我最近给被试（共5人）扫静息态fMRI时得出的结果均为头动大于3，配准后的图像无法使用。机子为飞利浦公司Achieva3T磁共振，2014年7月机器系统升级，之后我扫描的被试头动开始变大，技师认为与机器升级无关。这台机器以往扫fMRI没有出现这种情况，我们给被试戴上耳塞，耳塞内再加一块海绵，再用鸟笼式固定器限制头动，最终结果仍然是头动大于3，目前没有好的办法解决。想向大家请教在扫描过程中有什么好的方法改善被试头动问题？3229 reads

Wed, 03/11/2015 - 10:09ilovec如题所示 我用的只有结构型MRI，经过VBM和双样本t检验，用rest提取了8个激活区作为roi，因为考虑到这些roi都包含了不同的脑区，然后选择了 Multiple label values in a single mask 然后将 theROITimeCourses(t) =mean(theTimePoint); 改为 theROITimeCourses(t) =sum(theTimePoint); 然后产生了如下结果： 在txt文本里的数值如下： 1....4924 reads

Sun, 03/01/2015 - 19:55千寻e老师，你好，我用dartel方法做VBM，开始图像中心点不怎么齐，当然也不太歪，用AlphaSim校正后，得到4个clusters，每个cluster体素都挺大，后来我调整了图像中心点，用同样的方法处理，但结果完全没有激活点，为什么会出现这种情况，请老师指点。2652 reads
