主要贡献如下: · PVTFormer架构:我们提出了一种新颖的基于编码器-解码器的架构,PVTFormer,它利用PVT v2作为骨干网络。该模型利用残差学习增强特征表示。通过结合PVT v2、Up block和Decoder block,我们构建了一个端到端的分割流程,优化了计算资源的同时保留了重要信息,显著提高了分割性能。 · 分层解码策略:我们的方...
SLIVER07 (Segmentation of the Liver Competition 2007) 是一个非常经典的用于对比增强 CT 中对肝脏进行分割的数据集,提供 20 例 CT 图像和肝脏标注用于训练,以及 10 例不公开标注的数据用于测试,最早用于 MICCAI 2007 的竞赛中。 在2007 年的背景下,医学图像分析领域非常缺乏良好的评估和比较。提出的分割算法之间...
Segmentation of Liver from Abdominal CT images has received much importance due to its complexity, as the intensity of the liver is quite similar to those of other organs surrounding it. Hence, intensity based edge operators fail to segment the liver accurately. In this work, an attempt has ...

This paper presents a liversegmentation method from a sequence of computer to mography images.We propose a novelballoon force that controls the direction of the evolution process and slows down the evolvingcontour in regions with weak or without edges and discourages the evolving contour from going...
This study proposes a new liver segmentation method based on a sparse a priori statistical shape model (SP-SSM). First, mark points are selected in the liver a priori model and the original image. Then, the a priori shape and its mark points are used to obtain a dictionary for the liver...
一、Liver segmentation 3D-IRCADb2010介绍 3D-IRCADb-01 数据库由 10 名女性和 10 名男性的 3D CT 扫描组成,其中 75% 的病例患有肝肿瘤。20个文件夹对应20个不同的患者,可以单独或联合下载。由于与邻近器官的接触、肝脏的非典型形状或密度、甚至图像中的伪影,肝脏分割软件可能遇到的主要困难。
