Test case 4: Single source centered in a shielded applicator

Task Group 186 provides guidance for commissioning model-based dose calculation algorithms (MBDCAs) in brachytherapy treatment planning systems. TG-186 recommends a two-level commissioning approach, including comparison of absolute dose and 3D dose distributions against reference calculations. To support implementation of these recommendations, the AAPM Working Group on Dose Calculation Algorithms in Brachytherapy developed a set of standardized virtual phantoms and benchmark dose distributions for commissioning high-dose-rate Ir-192 sources. Four test cases were created, as described by Ballester et al. This dataset refers to Test Case 4. Note: This dataset was originally hosted on the IROC platform, as described in the user guide. The files uploaded to Zenodo (version 1) are identical to those previously available from IROC and were transferred without modification to ensure full traceability and continuity with the original reference dataset.
