The ability of an imaging system to accurately identify patient anatomy and provide reliable tumor information is critical in the radiation treatment planning process. As image guided radiation therapy and adaptive radiation therapy become more prevalent in treatment procedures, the image quality of these systems could perhaps be a limiting factor in their effectiveness. This research is intended to explore the differences in image quality between two separate imaging modalities commonly used in radiation therapy. A Philips Gemini TF Big Bore PET/CT and Varian True Beam On-Board kV cone beam CT imager were both assessed using the Catphan 504 image quality phantom. Ten different tests were evaluated with the phantom using several routine imaging protocols from both systems. Overall, the image quality between the cone beam and CT system was fairly consistent with one another with the exception of the low contrast detectability measurements. The effects of scatter radiation and image noise significantly reduced the cone beams ability to detect low contrast objects which ultimately degraded its image quality compared to CT.
