基于PC的医学图像体绘制方法研究与仿真

Research and simulation on medical image volume rendering Based on PC

体绘制技术是一种能够准确反映体数据内部信息的可视化技术。本文主要介绍了一种改进的体绘制算法,即首先对三维医学图像施加模糊增强,然后对增强后的图像进行模糊阈值分割,从而可以清晰地对三维数据场进行分类,即边界区与非边界区。对边界区与非边界区分别进行绘制。在PC机上进行仿真的结果表明,此方法既能提高绘制的速度,又能保证绘制质量。

Volume rendering techniques is a kind of volume visualization technique,which can reflect the inside information of the volume data. This paper mainly introduces a improved volume rendering algorithm,which firstly puts fuzzy enhancement operation on 3D medical images,then takes fuzzy thresholding segmentation,and clearly classifies the three dimensional data fields as edge region and non-edge range,renders them respectively finally. The results on PC shows that this method can improve the speed and accuracy of mapping.
