说明：  本程序可以从一定目录下搜索DICOM文件并构建3D图像，并且可以从3个维度显示图像。
(The interactive viewer allows a user to select a folder with one set of dicom images. The viewer assembles the images in order and displays them as one 3D dataset. User can then scroll through and look at axial, sagittal, and coronal views. A zoom feature and measuring tool have also been added.)
