To enable medical CBIR system to guarantee the meaningful queries with priorly specified image class, a novel coding scheme so-called MOAB, which consists of four axes: Modality, Orientation, Anatomy, and Biology, is proposed.

• 其中，为了确保医学图像的CBIR系统能够在特定图像类别下进行有意义的查询处理，我们结合成像设备(Modality)、体位方向(Orientation)、解剖部位(Anatomy)和生物系统(Biology)等四项信息设计了新颖的医学图像MOAB分类编码系统。
