Digital reconstructed radiograph (DRR) constitutes an important tool in clinical radio-oncology. In this paper, a Fourier volume rendering (FVR) method is proposed, enabling real time preview of DRR. Important aspects related to re-sampling into the frequency domain are examined, leading to results of high quality. Experiments using phantom and clinical data sets are presented, demonstrating the effectiveness of the method for a real time execution. Furthermore, due to the inherent parallelism of the proposed algorithm, its execution time can be further reduced by distributing the required computations to more than one processors. The computational efficiency of the method highlights its suitability for integration into a web-based radiation treatment planning (RTP) system, using a client-server architecture. Thus, platform independent, real time tele-cooperation in clinical radio-oncology can be achieved. (C) 2002 Elsevier Science Ltd. All rights reserved. (EN)
