ULMDOS is a new software tool for dosimetry calculations before radionuclide therapy. It streamlines calculations, improves data traceability, and ensures adequate documentation for clinical use.
Area of Science:
- Medical Physics
- Nuclear Medicine
Background:
- Accurate dosimetry is crucial for radionuclide therapy.
- Current methods can be time-consuming and lack standardization.
Purpose of the Study:
- To introduce ULMDOS, an interactive software tool for dosimetry calculations.
- To enhance traceability and documentation in radionuclide therapy planning.
Main Methods:
- ULMDOS is developed in IDL 6.1 for Windows.
- It integrates patient data, radiotracer information, and gamma camera images.
- Calculations involve fitting time-activity data to exponential functions for residence times.
Main Results:
- ULMDOS facilitates dosimetric calculations and data management.
- It enables standardized processing, reducing data transfer needs.
- The software supports documentation of regions of interest and raw data.
Conclusions:
- ULMDOS provides a standardized environment for dosimetry.
- It enhances traceability and reduces intraindividual variability.
- The tool meets prerequisites for routine clinical application in radionuclide therapy.
