Article Synopsis
- This study compared the accuracy and time efficiency of different tally methods using MCNP6 for a novel x-ray tube designed for Auger electron yield with materials like iodine.
- Key assessments included photon spectrum analysis, dose measurements in both air and water, and mass-energy absorption coefficients, showing slight variations in mean energy between different media.
- The FMESH tally method demonstrated better efficiency over the F6 tally for dose calculations, which could enhance treatment planning systems by quickly generating necessary data for diverse physical conditions.
Purpose: Transmission-target x-ray tubes generate more x-rays than reflection thick-target x-ray tubes. A transmission x-ray tube combined with radiosensitizers has a better radiation enhancement effect. This study investigated the feasibility of using a transmission x-ray tube with radiosensitizers in clinical radiotherapy and its effect on radiation dose enhancement.
