Interactive physically-based X-ray simulation: CPU or GPU?

摘要: Interventional Radiology (IR) procedures are minimally invasive, targeted treatments performed using imaging for guidance. Needle puncture ultrasound, x-ray, or computed tomography (CT) images is a core task in the radiology curriculum, and we currently developing training simulator this. One requirement to include support physically-based simulation of x-ray from CT data sets. In this paper, demonstrate how exploit capability today's graphics cards efficiently achieve on Graphics Processing Unit (GPU) compare performance with an efficient software only implementation Central (CPU).
