Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Some radiation therapy treatment plans require the use of boluses. Boluses are placed directly on the skin overlying the area to be treated. The radiation beam interacts with the bolus before entering the body and ensures that the correct radiation dose reaches your tumor. The purpose of this study is to determine whether the shortcomings of conventional bolus preparation can be overcome by using a 3D printer. CT scans of the body can be used to create 3D models for boluses. The 3D models can then be printed into plastic boluses using a 3D printer. Preliminary studies have shown that 3D printed boluses conform to body contours better and allow for more precise control over radiation dose. In this study, both a conventional and 3D printed bolus will be made. The Investigators will then simulate treatment with both boluses to determine which bolus will result in more optimal treatment for the participant. The superior bolus will be used in the participant's treatment.
