治疗乳腺癌的主要问题是肿瘤的早期检测和小体积乳腺（乳房）组织的准确活检。本报告提出了一种弹性配准算法的两个X射线乳腺摄影和相应的磁共振成像（MRI）体积。为了科普乳房摄影过程中乳房软组织的变形，使用乳房变形行为的二维模型作为弹性变换。采用归一化互信息作为相似性的度量。将未压缩的X射线乳房摄影中的感兴趣区域投影到MRI体积中以确定其三维原点。
Major problems in treating breast cancer are the early detection of tumors and accurate biopsy of small volumes of breast (mamma) tissue. This report presents an elastic registration algorithm of two x-ray mammograms and a corresponding magnetic resonance imaging (MRI) volume. To cope with the soft tissue deformation of the breast during mammography, a two-dimensional model of breast deformation behavior is used as an elastic transformation. Normalized mutual information is employed as a measure of similarity. Regions of interest in the uncompressed x-ray mammograms are projected into the MRI volume to determine their three-dimensional origin.
