摘要:
三维动态超声具有非常广泛的发展前景和临床应用。但是三维动态超声的数据结构不属于三维规则数据场,所以不能直接在微机上采用三维纹理加速算法实现实时体绘制。本文首先介绍了基于微机平台的针对三维规则数据场三维纹理体绘制加速算法。通过现代微机显卡结构的分析讨论,本文提出了利用现代微机显卡中的顶点渲染器编程实现三维动态扇扫数据场到三维规则数据场的快速变换,然后利用显卡中的三维纹理快速运算功能,从而在普通微机平台上实现了三维动态超声的实时体绘制。本方法具有很广泛的应用价值。 更多还原
Abstract:
Dynamic 3D ultrasound is a very promising technology for clinical use,but not being a Cartesian 3D dataset,3D ultrasound data can not be visualized directly with real-time volume rendering accelerated by 3D texture hardware.In this paper,fast volume rendering using 3D texture hardware acceleration is introduced and modern PC graphics card architecture analyzed.A modified method is proposed to obtain real-time volume rendering of dynamic 3D ultrasound data by programming vertex shader in GPU.Experimental results show that 3D ultrasound data can be rendered with real-time speed in normal PC platform.The method can be widely applied in future 3D dynamic ultrasound clinical research.
