Design of CT pictures from 2D to 3DLin, Lin 09 1900 (has links) (PDF)
Volume visualization is one important part of scientific visualization. It has developed basing on absorbing the relative knowledge of computer delineation, computer visualization and computer image disposal. The knowledge of this branch is of much importance in computer application. Since it deals with contents with deeper meaning and it is more theoretic, having more arithmetic means, it generally stands for the level of computer application. The study and application of volume visualization is like a raging fire. My country started comparatively later in this field. This thesis gives systematic representation and discuss in the field of tomography image 3D reconstruction. It mainly discusses after rotation, translation, filtering, interpolation and sharpening a series of 2D CT scanning images, get the boundary data of different object to form 3D volume data and actualize the 3D reconstruction of the object, and at the same time implement the function of display, translation, rotation, scaling and projection the volume data. Basing on the implementation of these functions according to software programming, this thesis gives a sum up to each algorithm of 3D volume visualization processing. The method to actualize the 3D reconstruction of the tomography image is mainly about the image processing, image transformation, the way to actualize 3D reconstruction and image compression, etc. In image processing, it talks about getting the anchor points in the tomography image, the geometrie transformation of the image, getting the boundary of the target, cross section display and the smoothing and sharpening of the image. In the transformation of the image, this thesis deals with the algorithm and implementation principle of the geometric transformation (transition, rotation, and scaling) of the 2D image, the three-dimensionalization of the planar data, construction of the stereo mode, geometric transformation of the 3D graph, curve-fitting, the processing of hidden line and hidden surface, color processing. It also introduces the thoughts of using OpenGL to develop and actualize tomography image 3D reconstruction system, including using OpenGL to transform the coordinate, solid model building, to actualize 3D rotation and projection. Recently, the methods of applying chemotherapy to deal with cancer in hospitals of our country are different. Hospital with great fund takes import software to design while most of the hospitals take domestic software. These kinds of software are designed by DAHENG Company in BeiJing, WEIDA Company in ShenZhen. The programs in the software these two hospitals' doctors use to treat are images fielding in the plane not making radiation design under the mode of omnibearing cubic display. Under this circumstance the judgment of the key part can not remain precise, and this part is the most important part that the doctors need. The above problem is the aim of this project. This thesis mainly deals with the subject that after calibrating and sharpening the series of 2D CT images, extract the boundary data of different bodies to form a 3D volume data and actualize 3D reconstruction and at the same time actualize the function of display, translation, rotation, scaling and projection. Mostly basing on the application of medical area, this thesis aims at making further research on computer graphies, computer vision and computer image processing through the study and application of volume visualization in this field. By the study and development of the volume visualization technology in this project, it can provide simulation and display functions to the observer before the operation and the radiotherapy as well as providing the chance to simulate the real teaching and practicing link to the medical school in the teaching process, and increase the clinic level and teaching level of medical area.
