摘要

我们提出了一种预处理和分割方案,旨在解决磁共振胆管胰胆管造影(MRCP)数据分析中遇到的特殊困难,作为计算机辅助诊断(CAD)技术应用的先驱。MRCP产生噪声,低分辨率,非等距数据,往往表现出显著的灰度不均匀性。这些特征的结合导致了难以实现可靠分割和分析的数据量。在本文中,我们描述了一种数据处理方法,以克服这些困难,并允许在MRCP检查中有效地应用自动CAD程序分析胆道树和胰管。

Analysis of the pancreato-biliary system from MRCP
We present a preprocessing and segmentation scheme designed to address the particular difficulties encountered in the analysis of magnetic resonance cholangiopancreatography (MRCP) data, as a precursor to the application of computer assisted diagnosis (CAD) techniques. MRCP generates noisy, low resolution, non-isometric data which often exhibits significant greylevel inhomogeneities. This combination of characteristics results in data volumes in which reliable segmentation and analysis are difficult to achieve. In this paper we describe a data processing approach developed to overcome these difficulties and allow for the effective application of automated CAD procedures in the analysis of the biliary tree and pancreatic duct in MRCP examinations.
