We present a fast GPU-based method for simulation of ultrasound images from volumetric CT scans and their visualization. The method uses a ray-based model of the ultrasound to generate view-dependent ultrasonic effects such as occlusions, large-scale reflections and attenuation combined with speckle patterns derived from pre-processing the CT image using a wave-based model of ultrasound propagation in soft tissue. The main applications of the method are ultrasound training and registration of ultrasound and CT images.
我们提出了一种基于GPU的快速方法，用于从容积CT扫描中模拟超声图像并进行可视化。该方法使用基于射线的超声模型来生成与视图相关的超声效果，如遮挡、大规模反射和衰减，并结合使用基于波的软组织超声传播模型对CT图像进行预处理得到的散斑图案。该方法的主要应用是超声培训以及超声图像与CT图像的配准。
