How do you check the calculation of the treatment planning system?

RadCalc – now a part of LAP



A fully automated import and export is much faster than manual entering of the necessary parameters. Thus it prevents human transmission errors.


Studies have shown the verification dose to be within +/– 3 % of the treatment plan dose providing unsurpassed accuracy.

Vendor independent

RadCalc® provides the opportunity to check all results independently from the manufacturer’s TPS. This ensures unbiased third party validation.


What commonly* takes 10-60 minutes/patient to verify a treatment plan MU dose is now reduced to minutes.


Most common treatment plans can be verified with RadCalc® QA software. Comprehensive analytical features provide powerful tools for physicists for plan analysis.


RadCalc® has an FDA 510(k) clearance and follows the guidelines for class II & IIb medical devices.
