Medical Image Visualization Technology To Achieve

Scientific visualization is a series of theory~ethod and technique,which apply computer graphics , image processing technique and human-computer intaading technique to transfonn the z~sulting data from the process of scientific computing to graphics and image that will be display in computer screen ,so that it can be interactively process. We apply scientific visualization technique to medical image data?ana]ysis and process. The target is that we sufficiently take into account the need of the medical image processing and the current condition of medical treatment equipment in china; aiming at CT or MRI image data,we make use of new technique and new achievement of current visualization research ,cariy out kinds of processing to medical image data on computer,to achieve many functions that can not be achieve on common imaging equipment,in order to make the processing funtion more stronger, infonnation more rich ,operalion more convenient.Vra visualization technique,we can redivivus organic抯 three dimension shape,and by vividly rendering ,we can see a brand-new world that never can be seen. In this thesis,a few dominating content of medical image visualization technique is discussed and researched,and a medical image visualization system is implementecL Firstly, visualization technique concept is intruducedAnd then a important application of visualization technique in medical fleld,namely medical image visualization technique, is imported~Sunvwiding this technique, a series of processing algorithms on medical image visualization processing is presented and implemented.These work mainly include: (1)image preprocessing that is the prophase work of visualization;(2)in order to resolve the modeling problem of skull and skin in Ninth-Five pz~ect~which is 揝kull to Skin Restoration?a seris of work is finished ,including contours distilling, convex hull based processing and surface rendering based 3D reconsinicting;(3) interactive dynamic volume rendering and its accelerating algorithm is innovatively presented,that makes the volume rendering speed reach almost to real time efflciency;(4) volume rendering based interactive real time virtual endoscopy algorithm is pzesented,that can generate vivid virtual endoscopy image of 3D effect;(5)at last,a few key techniques are presented that apply visualization technique to lnternet,namely Web based 3D visualization. By dint of Web technique抯 strong ability on data communicating ,it make visualization technique achieve more widely application value and get more broad generalization and development All of the algorithms in this thesis is implemented on microcomputer platform using Visual C~-$- or JDKI.3, and the algorithms抯 couectness and high efficiency got validated. Medical image visualization,which is the research hotspot of current medical image processing is not only significant in theory research,but also very important and helpful to clinic diagnosing and medical jurisprudence. Its effect to medical treatment modernization would be revolutionary and far-reachingand would produce good social benefit and big economic profit...
