Sensitivity and specificity of Monte Carlo based independent secondary dose computation for detecting modulation-related dose errors in intensity modulated radiotherapy
CONCLUSIONS: ISDC with Monte Carlo proves highly efficient to catch errors in the treatment planning process. For a Monte Carlo based TPS, dose-difference criteria of 2% or less, and distance-to-agreement criteria of 1 mm, achieve the largest AUC in ROC analysis.PMID:37891103 | DOI:10.1016/j.zemedi.2023.10.001 (Source: Zeitschrift fur Medizinische Physik)

Impact of the maximum ring difference on image quality and noise characteristics of a total-body PET/CT scanner
CONCLUSION: Patient and phantom studies revealed that scan time could be lowered by approximately a factor of two with MRD322 while maintaining similar noise performance. The moderate degradation in spatial resolution for MRD322 is worth to exploit the full potential of the Quadra by either shorten scan times or leverage noise performance in particular for low count scenarios such as ultra-late imaging or dynamic studies with high temporal resolution.PMID:37867050 | DOI:10.1016/j.zemedi.2023.09.001 (Source: Zeitschrift fur Medizinische Physik)
