dosimetric analysis
Pronunciation: dose-ih-MET-rik
Quantitative evaluation of radiation dose distribution to target volumes and normal tissues in treatment planning.
Full Definition
Dosimetric analysis involves the systematic evaluation of radiation dose distributions within a treatment plan, including assessment of target volume coverage, critical structure doses, and plan quality metrics. This analysis typically includes dose-volume histogram review, conformity indices, homogeneity indices, and comparison of doses to established tolerance limits. Dosimetric analysis is fundamental to treatment plan approval, quality assurance, and clinical research in radiation oncology. For medical editors, understanding dosimetric terminology is essential for reviewing treatment planning studies, clinical protocols, and comparative treatment analyses where quantitative dose metrics are reported.
