Extraction of virtual slice on 3D medical image based on VTK
基于VTK的三维医学图像虚拟切片提取

The images from most medical imaging equipments such as CT,MRI must be along some fixed direction,but it can't satisfy the clinical inspection from arbitrary directions and angles.In view of this problem,this paper proposed the method of any angle extraction of virtual slice on 3D medical images.Adopted VC 6.0 with VTK to reconstruct the 3D images using the 2D CT image sequence in DICOM format.The vector and inner point were calculated to form the virtual clipping plane,which in turn was used to incise the 3D object.And obtained the information of virtual slice,in the mean while displayed the virtual slice images on the screen.By simple interactive operations like using mouse,the image scaling,translation and rotation could be realized in real-time.Therefore,the presented method is an effective complement to present medical imaging equipments.
