WE-E-BRB-11: Riview a Web-Based Viewer for Radiotherapy.

Area of Science:

• Medical Physics
• Radiotherapy
• Radiogenomics

Background:

• Collaborative research in radiotherapy, such as the international radiogenomics consortium, requires effective tools for managing treatment planning data.
• Existing methods for reviewing radiotherapy data can be cumbersome and may not be web-based.

Purpose of the Study:

• To present the architecture and prototype characteristics of a web-based radiotherapy viewer.
• To develop a tool that facilitates the review of treatment planning information for collaborative studies.

Main Methods:

• Leveraged CERR for DICOM/RTOG data import and conversion to RT objects.
• Stored scan and dose distributions as .png files, with locations in a MySQL database.
• Developed a web application using HTML5 and Ruby on Rails (RoR) with ImageMagick for visualization.

Main Results:

• A prototype system, RIVIEW, was developed and tested using lung cancer patient data.
• The system successfully made scans, doses, structures, and DVHs for 10 patients available via the web interface.
• Five user accounts were created for accessing the study data.

Conclusions:

• A web-based system (RIVIEW) was prototyped to facilitate quality assurance, querying, retrieval, and visualization of radiotherapy data.
• The RIVIEW system utilizes open-source technologies (MySQL, RoR) for accessibility and cost-effectiveness.
• Future plans include extending RIVIEW for clinical trial data collection, outcomes research, and cohort plan review.
