With recent interest in patient-specific dosimetry for radiopharmaceutical therapy (RPT) and selective internal radiation (SIRT), an increasing number of voxel-based algorithms are being evaluated. Monte Carlo (MC) transport, generally considered to be the most accurate among different methods voxel-level absorbed dose estimation, can computationally inefficient routine clinical use.
