ABSTRACT
Digitally reconstructed radiographs (DRR) which greatly contribute to the quality control of radiotherapy are critical element in the process of virtual simulation in radiotherapy. In this paper, an algorithm based on ray tracing has been used to generate the DRR. By applying an exponential transformation to the electronic density determined by CT value, the generated DRR can be enhanced by adjusting the attenuation and the transformation parameter.
