Soft-tissue imaging in the treatment room is one of the main challenges faced today in high precision radiotherapy. The objective of this work is to evaluate a new anthropomorphic male pelvic phantom (CIRS Inc., Norfolk, VA, USA) that can be used in a radiotherapy department to assess the ability of an X-ray imaging system for imaging soft-tissue targets in the treatment room. To this end, we evaluated the tissue-equivalency of the phantom materials in terms of the linear attenuation and energy

Our results demonstrated that the male pelvic phantom is a good representation of actual prostate cancer patients and can be a valuable tool for image-guided radiotherapy.
