Summary
Transitioning from paper-based to electronic quality control (QC) systems for external beam radiotherapy equipment significantly improves data management. This digital approach enhances machine performance analysis and reduces errors in radiotherapy QC.
Area of Science:
- Medical Physics
- Radiotherapy Technology
- Quality Assurance
Background:
- Traditional paper-based quality control (QC) for external beam radiotherapy equipment is labor-intensive for data calculation and processing.
- Maintaining equipment performance through rigorous QC is crucial in radiotherapy.
- Electronic data recording offers enhanced data analysis, trend identification, and potential component failure prediction.
Purpose of the Study:
- To describe the implementation of an electronic system for QC data recording and processing.
- To replace a resource-intensive paper-based system with a more efficient digital solution.
- To detail the benefits of electronic data management in radiotherapy equipment QC.
Main Methods:
- Developed an electronic QC data recording system using Microsoft Excel macros.
- Utilized personal digital assistants and networked laptops for online data entry.
- Employed networked desktop PCs for offline data processing and analysis.
- Implemented automated calculations and charting for trend analysis.
Main Results:
- Successfully replaced the paper-based QC system with an electronic one for linear accelerators and superficial units.
- The electronic system provides secure data storage, backup, and archiving.
- Automated calculations and charting reduce operator errors and facilitate trend analysis.
- Centralized data management enhances the security and accessibility of QC records.
Conclusions:
- The implemented electronic QC system offers numerous benefits, including improved data security, reduced calculation errors, and enhanced analytical capabilities.
- This digital transition streamlines the QC process for radiotherapy equipment.
- Future development aims to extend similar electronic systems to other radiotherapy equipment.
