Real time digital reconstructed radiograph (DRR) rendering in frequency domain
1999
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.
