TomoTherapy Delivery Quality Assurance (DQA) using Delta4—preliminary study

摘要：

Purpose:To test the capabilities of the Delta43D dose phantom with TomoTherapyTM HiART IITM for high dose per fraction treatments typically delivered with stereotactic body radiation therapy (SBRT) techniques.Implementation of the Delta4 system for SBRT delivery verification overcomes the current necessity to scale the DQA procedure in order to ensure that the maximum dose delivered is within the dynamic range of the film being utilized.By using the Delta4,scaling errors,primarily due to the MLC leaf latency,would be minimized or eliminated,and the un-scaled treatment plan would be verified.
