This paper describes a region-growing algorithm for the segmentation of large lesions in T/sub 1/-weighted magnetic resonance (MR) images of the head. The algorithm involves a gray level similarity criterion to expand the region and a size criterion to prevent from over-growing outside the lesion. The performance of tile algorithm is evaluated and validated on a series of pathologic three-dimensio...

本文描述了一种用于头部T1加权磁共振（MR）图像中大病变分割的区域生长算法。该算法采用灰度相似性准则来扩展区域，并利用尺寸准则防止区域过度生长到病变外部。该算法的性能在一系列病理三维...上进行了评估和验证。

A new approach is proposed for registering a set of histological coronal two-dimensional images of a rat brain sectional material with coronal sections of a three-dimensional brain atlas, an intrinsic step and a significant challenge to current efforts in brain mapping and multimodal fusion of experimental data. The alignment problem is based on matching external contours of the brain sections, an...

提出了一种新方法，用于将一组大鼠大脑冠状组织学二维切片图像与三维脑图谱的冠状切片进行配准，这是当前脑图谱绘制和多模式实验数据融合工作中的关键一步和重大挑战。配准问题基于匹配脑切片的外部轮廓，

The ideas of parallel imaging techniques, designed to shorten the acquisition time by the simultaneous use of multiple receive coils, can be adapted for parallel transmission of a spatially selective multidimensional RF pulse. In analogy to data acquisition, a multidimensional RF pulse follows a certain trajectory in k-space. Shortening this trajectory shortens the pulse duration. The use of multi...

并行成像技术的思路，通过同时使用多个接收线圈来缩短采集时间，可以适用于空间选择性多维射频脉冲的并行传输。与数据采集类似，多维射频脉冲在k空间中遵循特定轨迹。缩短该轨迹可缩短脉冲持续时间。使用多...
