Validating a framework for Pinnacle plan conversion and archival.

Area of Science:

• Medical Physics
• Radiation Oncology
• Data Management

Background:

• Pinnacle treatment planning system support ends December 31, 2026.
• Access to historical patient treatment data is crucial for continued care.
• A validated method for accessing Pinnacle data is required.

Purpose of the Study:

• To validate Sun Nuclear Gateway as a solution for converting Pinnacle TAR data to DICOM format.
• To ensure continued access to patient treatment records beyond Pinnacle's support life.
• To archive over 20,000 patient treatment plans from multiple Pinnacle versions.

Main Methods:

• Utilized Sun Nuclear Gateway to convert Pinnacle TAR files to DICOM.
• Archived data including images, structures, and dose re-sampled to 2 mm.
• Validated conversion accuracy through quality checks and 3D gamma analysis (1%/1 mm).

Main Results:

• Successfully converted and archived data for 8 Pinnacle versions.
• Achieved an average 3D gamma pass rate of 99.96%.
• Observed a low conversion error rate of 0.5% after initial adjustments.

Conclusions:

• Sun Nuclear Gateway is a validated solution for converting Pinnacle TAR data to DICOM.
• This facilitates access to essential historical treatment planning data.
• Ensures continuity of care for patients treated with Pinnacle.
