AIM
The main objective of the study was to analyze the structure of data contained in the archives exported from a tomotherapy treatment planning system. An additional aim was to create an application equipped with a user-friendly interface to enable automatic reading of files and data analysis, also using external algorithms. Analyses had to include image registration, dose deformation and summation.
MATERIALS AND METHODS
Files from the archive exported from the tomotherapy treatment planning system (TPS) were analyzed. Two programs were used to analyze the information contained in the archive files: XML Viewer by MindFusion Limited and HxD hex editor by Maël Hora. To create an application enabling loading and analyzing the data, Matlab by MathWorks, version R2009b, was used.
RESULTS
Archive exported from the TPS is a directory with several files. It contains three types of data: .xml, .img and .sin. Tools available in Matlab offer great opportunities for analysis and transformation of loaded information. Proposed application automates the loading of necessary information and simplifies data handling. Furthermore, the application is equipped with a graphical user interface (GUI). The main application window contains buttons for opening the archives and analyzing the loaded data.
CONCLUSION
The analysis of data contained in the archive exported from the tomotherapy treatment planning system allowed to determine the way and place of saving information of our interest, such as tomography images, structure sets and dose distributions. This enabled us to develop and optimize methods of loading and analyzing this information.
目的
本研究的主要目的是分析从螺旋断层放射治疗计划系统导出的存档中包含的数据结构。另一个目的是创建一个配备用户友好界面的应用程序，以实现文件的自动读取和数据分析，同时也使用外部算法。分析必须包括图像配准、剂量变形和求和。
材料与方法
对从螺旋断层放射治疗计划系统（TPS）导出的存档文件进行分析。使用了两个程序来分析存档文件中包含的信息：MindFusion Limited公司的XML Viewer和Maël Hora的HxD十六进制编辑器。为了创建一个能够加载和分析数据的应用程序，使用了MathWorks公司的Matlab，版本为R2009b。
结果
从TPS导出的存档是一个包含多个文件的目录。它包含三种类型的数据：.xml、.img和.sin。Matlab中可用的工具为加载信息的分析和转换提供了很大的机会。所提出的应用程序实现了必要信息的自动加载并简化了数据处理。此外，该应用程序还配备了图形用户界面（GUI）。主应用程序窗口包含用于打开存档和分析加载数据的按钮。
结论
对从螺旋断层放射治疗计划系统导出的存档中包含的数据进行分析，能够确定保存我们感兴趣信息（如断层扫描图像、结构集和剂量分布）的方式和位置。这使我们能够开发和优化加载和分析此信息的方法。
