摘要
为解决二维医学图像无法充分展示细节的问题,实现硼中子俘获治疗中精确有效的三维可视化.对传统移动立方体算法进行改进,在图像插值时,采用中值法替代线性插值方法,减少运算次数,最后将重建结果使用QT进行可视化效果呈现.以人体头部DICOM数据为例进行三维重建的结果表明,相较于2D图像仅提供局部平面信息,改进后的移动立方体算法重建模型能够从更加完整的角度提供三维结构信息,具有更好的重建效率.
Abstract
To solve the problem that two-dimensional medical images cannot adequately show the details and to achieve precise and effective three-dimensional visualization in boron neutron cap-ture therapy.This is achieved by improving the traditional marching cubes algorithm.During image interpolation,the median method replaces the linear interpolation method,reducing com-putational load.The final reconstruction results are visualized using QT.Using DICOM data of a human head as an example,the three-dimensional reconstruction demonstrates that,unlike 2D images that provide only partial plane information,the improved marching cubes algorithm re-construction model offers more comprehensive three-dimensional structural information from a more complete perspective and achieves better reconstruction efficiency.
