Part of the Digital Twin product family
Know what your machine is actually doing.
Traditional QA asks, "Is the machine within tolerance?" SIMAC Quality Assurance asks, "What is my machine actually doing?" — by matching the beam model to your own QA data.
A QA data-integration system that pulls your real linac QA data into SIMAC and matches the beam model to what your machine is outputting today — not the model it was commissioned with. From there you can change machine parameters and see the effect on water tank scans, or investigate a drift back to the subsystem behind it — with trend analysis and machine history for life-cycle management. Powered by the patent-pending SIMAC Beam Model.
Match the beam model to the machine you have today.
Your commissioning beam model describes the linac as it was on the day it was commissioned. Every month since, the machine has drifted a little further from it. SIMAC Quality Assurance matches the beam model to what your machine is actually outputting now, using the QA data you already collect — so the model you reason with is current instead of historical.
Paired with SIMAC Dose Calculation, that current model lets you see the combined effect of several drifts on your patient's dose — the accumulation that no single TG-142 test flags, because each parameter is still inside tolerance on its own.
What you can do
- Match the beam model to today's machine — the drift away from your commissioning model, quantified.
- Change machine parameters and see the effect on water tank scans.
- Trace a drift back to the subsystem behind it — and separate user effects from true machine effects.
- With SIMAC Dose Calculation, see the combined dose effect of several parameter shifts on a patient plan.
- Set up a TG-100 FMEA framework with patient-risk scores; support lifecycle and capital planning.
What's included
- QA data integration into a machine-specific digital twin
- Trend analysis & machine history for service support
- Beam model matched to your machine from imported QA data
- QA import over a simple TotalQA® API — or a reduced version using stock or manually entered data
- Requires SIMAC Machine as a base product
- Dose calculation is not included — dose distribution effects require SIMAC Dose Calculation
We work with Image Owl to import your QA data.
Your QA results reach SIMAC through a simple API connection to TotalQA®, Image Owl's cloud QA platform. No manual export, no spreadsheet assembly — the data you already collect flows straight into the beam model.
Connect it with a simple API key and your existing QA history populates the digital twin.
We can help you get TotalQA — talk to us and we'll introduce you to Image Owl to learn more.

What it does — and doesn't do today
SIMAC Quality Assurance is an add-on to SIMAC Machine. It works in machine and beam-data space — parameters, scans and trends. To see dose distribution effects you need SIMAC Dose Calculation, which is a separate product.
- ›Matches the beam model to today's machine, not the commissioning baseline
- ›Shows the effect of parameter changes on water tank scans
- ›Supports TG-100 risk frameworks and patient-specific QA
- ›Keeps machine history for audit readiness and service
- ›Does not model MLC log files or electron beams
- ›No dose distribution calculation — that is SIMAC Dose Calculation, sold separately
- ›Only imports data from TotalQA
SIMAC Machine is the base product.
Start with SIMAC Machine — the virtual linac matched to your accelerator. Add the commissioning water tank, Quality Assurance, or Dose Calculation individually, or take all of them together as SIMAC Digital Twin.
Two product families, one platform.
SIMAC Training products teach the machine — every one of them includes SIMAC Learning and the SIMAC Machine Education Edition. SIMAC Digital Twin products model your machine — sold per machine, per beam model, and all built on SIMAC Machine as the base.
Includes SIMAC Learning + SIMAC Machine or free SIMAC access

QA data import powered by TotalQA® from Image Owl, a beam model matched to your own machine, parameter investigation against water tank scans, and trend analysis with machine history. Dose calculation is not included.
Your QA program or TG-142 testing. It interprets the results you already collect — and it requires SIMAC Machine as the base product.
