correlation ratio(相关比):默认,常用于MRI模态之间 mutual information(互信息):常用于不同影像模态之间,如CT和MRI least squares(最小二乘法):用于相同模态 normalized correlation(标准化相关):用于相同模态,改变亮度,对比度 normalized mutual i...
mris的汉语意思如下：abbr.海事研究情报处(Maritime Research Information Service);主雷达跟踪站;战备物资索引系统(Material Readiness Index System)。mris的造句如下：Objective Designing segmentation of brain MRIs based on neural networks.目的：设计适用于颅脑磁共振图像分割的神经网络算法。You need mor...

Neither method of summarizing information from T2-weighted scans is strongly related to measures of the clinical course of disease as assessed by the EDSS or SNRS. 展开 关键词: Guillain-Barre syndrome acute motor axonal neuropathy (AMAN acute motor sensory axonal neuropathy (AMSAN Fisher's syndrome...
A mutual information (MI) based registration method is introduced to align the rat brain tissues in MRI time-series, which is critical to the MRI tracer method for quantitative analysis of brain extracellular space (ECS). Specially, two works have been done to address the specific properties of...
磁共振(MRI)是一种常用的影像学检测手段。相对于X线和CT检查,MRI对人体没有辐射影响,并且可以更加清晰地显现人体各种软组织结构,是医生临床诊断的有力帮手。 但是,MRI检查也有一些禁忌,比如体内不能带有磁性金属物。所以,很多做了人工关节手术或即将手术的病人很关心的一个问题是:人工关节置换术后,是否还能做MRI检...
A fuzzy information fusion method is proposed in this paper. It can automatically classify abnormal tissues in human brain in a three dimension space from multispectral magnetic resonance images such as T1-weighted, T2-weighted and proton density feature images. It consists of four steps: data matc...
据报道,在新生儿中脑积水与唐氏综合征的发病率几乎相当,约为0.1%~0.6%,而脑积水在成人中的发病率约为1.0%~1.5%,并有逐年增长的趋势。目前脑积水的诊断主要依靠临床表现及影像学检查。 近年来,磁共振相位对比电影成像(phase contrast cine magnetic resonance imaging,PC-MRI)因其无创操作的优点越来越受到关注,被...
