Total Body Irradiation Aluminum Compensators

Abstract

We propose the utilization of waterjet-fabricated aluminum compensators in total body irradiation (TBI) treatments using the technique known as AP/PA. Lead was substituted with aluminum to create a safer and more efficient compensator design, which was then constructed using SOLIDWORKS. The Engineering Innovation Center at Texas A&M University used a ShopBot Auto Router to fabricate the final prototype. In future directions, the prototype’s performance will be analyzed by measuring surface dose information using an anthropomorphic phantom. From this information the uniformity of dose distribution will be assessed and compared to that of current lead compensators to determine the efficiency of the proposed substitution.
