Abstract

DRR is an important technique in radiotherapy imaging application and its real time rendering is critical in radiotherapy treatment planning. A method for the real time rendering of DRR in the frequency domain is presented. Different solutions based on the trade-off between speed and image quality are proposed among different applications. The technique has shown to be effective using both phantom and clinical data sets
