Yunfeng Cui, PhD, resident/researcher in Thomas Jefferson University's CAMPEP accredited Medical Physics residency program, was selected to give an oral presentation during the 2009 ASTRO IGRT scientific session. His talk focused on the use of three different IGRT hardware and software systems comparing registration of prostate and head and neck scans. Dr. Cui and collaborators conclusion: "Significant differences were observed when different registration systems were used to obtain IGRT shifts from the same planning and daily image sets as compared with those shifts used for patient treatments. Careful examination and quality assurance of the image registration process are needed before considering margin reduction using IGRT."
