3D reconstruction of medical image based on OpenGL is a complex process, in which 3D surface rendering is the most widely used in medical diagnosis and treatment. In this paper, we introduce the whole process of 3D surface rendering in detail. 1. Reading in medical sequence image files; 2. Interpolating based on layer thickness and scale factor; 3. Adjusting window width/center and converting 16bit raw data to 8bit display data. 4.Making three orthogonal planes(axial, sagittal and coronal). 5. Making 3D skin points and computing their normal vectors. 6. 3D surface rendering based on OpenGL. 7. Dragging with the mouse, 3D image can rotate the x, y, z axis. |
