A: represents a perspective view showing the model of the phantom, the accelerator and the radiotherapy room. Also shown in detail are the modeling of the phantom, of the accelerator, and of the head of the accelerator. The housing surrounding the equipment head is merely illustrative and has not been simulated. B: represents a general view of the modeled accelerator obtained by the Visual Editor, where the accelerator head can be observed at zero degrees and a longitudinal and cross section of the phantom, left and right images, respectively.
