SATDose Monte-Carlo CT Dosimetry Calculator: Calculate patient-specific CT radiation and organ doses accurately using our advanced dosimetry calculator.
🩻 CT Dosimetry Calculator
Comprehensive dose estimation based on ImPACT CT Dosimetry methodology • AAPM TG-204 / TG-236
🔧 Scanner & Protocol
👤 Patient Parameters
⚠️ Paediatric Mode Active
Dose calculations use paediatric conversion factors (k-factors) per AAPM TG-204. Effective dose will be adjusted for age-specific tissue weighting.

ℹ️ How to use this calculator:
1. Select your CT scanner manufacturer and model (or use generic values).
2. Choose the anatomical protocol — this auto-populates typical scan parameters.
3. Enter patient details. For paediatric patients, select the appropriate age group.
4. Adjust scan parameters (kVp, mAs, pitch, collimation, scan length).
5. Click Calculate Dose to see CTDIvol, DLP, SSDE, and effective dose estimates.

Educational and Demonstration Purposes Only
The SATDose Monte-Carlo CT Dosimetry Calculator is a browser-based sample tool designed solely for educational, informational, and demonstration purposes. All calculations, radiation transport simulations, and parameter adjustments are performed locally within your web browser. No clinical files, patient records, or medical images are uploaded to our servers, transmitted, or stored.
Not for Clinical Decision-Making
The results generated by this calculator are statistical estimates based on generalized mathematical models and computational phantoms. They do not constitute direct physical radiation measurements and must NOT be used for direct patient measurements, clinical diagnostic decisions, or legal medical documentation. Actual radiation exposure can vary significantly based on real-world patient anatomy, technical scanner calibration variations, physical filtration differences, and software updates. Always consult a certified medical physicist or diagnostic radiologist to verify specific institutional protocols and equipment safety metrics.
