Clinical Tools
Calculators and reference tables for radiosurgery and radiation oncology. Each tool states its model and sources. Built for teaching and discussion; for patient care, use the approved treatment plan and your team's dose constraints.
Calculators
Radiosurgery Dose Calculator
SRS BED with treatment time, pre-plan falloff and V12Gy by target size and platform, renormalization, and normal tissue risk.
BED, EQD2, Re-irradiation and Treatment Gap Calculator
BED and EQD2 at any α/β, isoeffect conversion, CNS re-irradiation sums, common schedules, and missed-day compensation.
An iPhone app with these calculators is in testing.
Reference tables
Radiosurgery Dose Tables
Trial schedules (RTOG 90-05, N107C, A071801, spine), TG-101/HyTEC/QUANTEC limits, and functional SRS doses.
CNS Radiation Toxicity: Management and Drug Doses
Necrosis, edema, seizures, neurocognition, nausea, spine SBRT and late effects, with drug doses, evidence type and sources.
Timing Radiation Around Systemic Therapy and Surgery
Drug hold intervals around SRS and fractionated RT, searchable by name, brand or class, plus pre- and post-op SRS timing.
Plan-Quality Metrics and Prognostic Scores
Conformity and gradient indices, BED/EQD2, prognostic scores (GPA; NOMS/SINS/ESCC), and TG-101/QUANTEC/HyTEC constraint references.
