摘要

In recent years, the use of hadrons for cancer radiation has grown in importance, and many facilities are currently operational or under construction worldwide. To fully exploit the therapeutic advantages offered by hadron therapy, precise body imaging for accurate beam delivery is decisive. A key component of its research is Discrete Range Modulated (DRM) method which will be converted a deposited energy of de-tector to Water Equivalent Thickness (WET) of the object. In this article, developed successfully Ray Tracing and MCNPX/DRM method, creating Proton Radiographies (pRGs) with a cone-beam source. Finally, using a Feldkamp- Davis- Kress (FDK) algorithm to create the reconstructed slice from these image projections. In addition to comparing each other with slice VIP-Man phantom, immersing Water Equiva-lent Ratio (WER) index.
