Approximation of the Ablation Zone for Radiofrequency Ablation utilizing a Shader Framework for Volume Rendering
Percutaneous radiofrequency ablation (RFA) is becoming a standard minimally invasive clinical procedure for the treatment of liver tumors. However, planning the applicator placement such that the tumor is completely destroyed, is a demanding task that requires considerable experience.

In this talk, a fast real-time approximation of the ablation zone incorporating the cooling effect of liver vessels is presented. Furthermore, a modular shader framework is proposed, which facilitates real-time visualization of the ablation zone in projected slice views and in direct volume rendering. The key idea of the novel framework is a dynamic shader pipeline, which is based on the SuperShader concept.
