Abstract

Comparison of uncompressed volumetric breast data to compressed projection mammographic data poses a variety of challenges to accurately localize anatomy in both data sets. This work presents a method for simulating the mechanical compression of volumetric breast data. We use an approach based on a rectilinear-grid finite-element mesh and apply the method to known objects including volumetric breast data. Overall results show good agreement with theory and reasonable qualitative agreement with clinical results. Analysis times are sufficiently short to be used in the clinical setting for data comparison. The methods presented here provide a high quality method for simulating mechanical compression of breast data.

摘要

将未压缩的乳腺容积数据与压缩的乳腺钼靶投影数据进行比较，在准确确定两个数据集中的解剖结构方面面临着各种挑战。这项工作提出了一种模拟乳腺容积数据机械压缩的方法。我们使用基于直角网格有限元网格的方法，并将该方法应用于包括乳腺容积数据在内的已知对象。总体结果与理论吻合良好，与临床结果在定性上也有合理的一致性。分析时间足够短，可用于临床环境中的数据比较。本文提出的方法为模拟乳腺数据的机械压缩提供了一种高质量的方法。
