A Software Tool of Extracting Dose Plane for Tomotherapy Delivery QA

Research output: Contribution to journalArticle

Abstract

Purpose: To develop a software tool to extract dose planes base on on the setup (red) laser positions for Tomotherapy delivery QA(DQA). Methods: We have a develop a simple tool to simplify a time‐consuming step for tomotherapy DQA. The DQA analysis tools in Tomotherapy software was useful for film dosimetry but not convenient for 2D‐array QA devices. Current DQA software requires the user to perform alignments twice: one for setting DQA phantom and the other for extracting dose plane. These two steps can be simplified into one if both alignments are based on the central axis of the detector plane. Once the setup (red) lasers are set for DQA, the dose plane can be extracted from the dicom dose file and the dicom plan file automatically. An open source software was written in C using dicomtk library. The accuracy of the program has been tested by comparing the extracted dose plane to the same dose plane but extracted by the manual method. Results: The maximum dose difference is 0.5% and the mean difference is 0.2%. The differences are probably due to the variation between two manual alignments. The software extracts 2D‐dose plane in a simple and automatic way. This not only cuts workload but also reduce the degree of human error because only one manual alignment is needed. A copy of this open source software is available upon request. We also hope Tomotherapy provides similar function in future upgrade. Conclusions: A software tool has been developed to simplify Tomotherapy DQA procedure.
