在本文中，我们描述了一种从胎儿脑超声（US）体积构建三维图谱的方法。提出了一种多通道群的Demons配准方法，将种群中的一组图像同时配准到一个公共参考空间，从而表示种群的平均值。与标准的Demons公式类似，我们的方法将强度图像作为输入，但有一个额外的通道，其中包含从强度通道提取的基于相位的特征。本文提出的多通道图谱构建方法使用分组分组的Dice重叠进行了评估，并被证明优于标准（单通道）分组差分的Demons配准。然后使用该方法从39个孕23周的健康胎儿群体中收集的美国脑容量构建图谱。由此产生的图谱显示出高度的结构重叠，并且观察到美国和年龄匹配的胎儿mri图谱之间的对应关系。
In this paper, we describe a method to construct a 3D atlas from fetal brain ultrasound (US) volumes. A multi-channel groupwise Demons registration is proposed to simultaneously register a set of images from a population to a common reference space, thereby representing the population average. Similar to the standard Demons formulation, our approach takes as input an intensity image, but with an additional channel which contains phase-based features extracted from the intensity channel. The proposed multi-channel atlas construction method is evaluated using a groupwise Dice overlap, and is shown to outperform standard (single-channel) groupwise diffeomorphic Demons registration. This method is then used to construct an atlas from US brain volumes collected from a population of 39 healthy fetal subjects at 23 gestational weeks. The resulting atlas manifests high structural overlap, and correspondence between the US-based and an age-matched fetal MRI-based atlas is observed.
