一、fMRI的空间分辨率 fMRI的空间分辨率的细粒度在原则上是比较不错的,它取决于BOLD的点分布和信噪比,而这些因素又建立在磁场强度、线圈到组织的距离和脉管系统。空间分辨率的上限大约在400微米左右,其实现条件是强磁场、高分辨率成像或者植入线圈(这个植入就不能在人类大脑上做啦,太恐怖了)。 举个例子来演示一下fMR...

In this article, the early history of fMRI methods is first described, followed by a description of the basics of the hemodynamic response as measured by fMRI. The rest of the article is a detailed description of the spatial resolution and temporal resolution limits of fMRI and how these ...
temporal 9.1.2.1Spatial resolution Spatial resolutionrefers to resolving the power of the sensor for distinguishing among the closely spaced objects. In other words, the spatial resolution is defined as the measurement of a small object, which is resolved by the sensor, or the ground area imaged ...
