Abstract
Virtual simulation allows to simulate the radiotherapeutic treatment by computer, based on a CT scan of the patient in treatment position. The routinely obtained CT scans of prostate cancer patients in treatment position were used after conventional simulation for a parallel virtual simulation. In a first step the three-dimensional electron density data of the CT were used to outline the prostate and critical organs as three-dimensional volumes of interest. Based on the 3D information of the pre-defined target volume and a pre-set 3D margin, beams and beam blocks were automatically generated according to the beam set-up. A beam`s-eye view of the volumes of interest was calculated for each beam, superimposed on a digitally reconstructed radiograph using the actual divergence of the beam. At the same time the dose distribution was computed for the fields and blocks generated by the virtual simulator. The resulting Dose Volume Histograms for prostate, rectum and bladder were reviewed and compared with the Dose Volume Histograms obtained from the conventional simulation process. During both virtual and conventional simulation, time commitments required for all the members of the radiotherapy treatment team were recorded. It is concluded that routine use of virtual simulation is possible in a busy
