The MABDOSE software is validated as a versatile tool for internal radiation dose assessment. Its dosimetry system accurately calculates radiation transport and absorbed doses, ensuring reliable internal radionuclide dosimetry applications.

Area of Science:

  • Medical Physics
  • Radiological Sciences
  • Computational Dosimetry

Background:

  • Internal radiation dose assessment is crucial for medical and research applications.
  • Accurate dosimetry software is essential for reliable internal radionuclide therapy and diagnostics.

Purpose of the Study:

  • To validate the MABDOSE software as a general-purpose tool for internal radiation dose assessment.
  • To verify the implementation of its internal dosimetry system through a comprehensive suite of tests.

Main Methods:

  • Digitalization of target organs and tumors, including organ replacement.
  • Calculation of cumulated activity using curve-fitting and mathematical modeling algorithms.
  • Simulation of radiation transport and dose calculation, validated against established reports (MIRD 3, Cristy-Eckerman).

Main Results:

  • MABDOSE organ volumes show good correspondence (<10% difference) with Reference Man data at 5 mm resolution.
  • Cumulated activity calculations demonstrated exact or convergent accuracy.
  • Absorbed fractions agreed well with MIRD 3 (<8% difference) and showed marginal agreement with Cristy-Eckerman.

Conclusions:

  • The MABDOSE program is validated as a reliable, general-purpose computation tool.
  • The software is suitable for internal radionuclide dosimetry applications.
  • The validation suite confirms the accuracy of its dosimetry system implementation.
