Part of the Digital Twin product family
A virtual linac that behaves like the real thing.
Investigate machine settings, estimate their effect on QA, and practice beam tuning before you touch a live accelerator — then connect a QA deviation to its probable fault. From QA failure to root cause in minutes instead of days.
Powered by the patent-pending SIMAC Beam Model, SIMAC Machine offers four interfaces: a graphical Machine Configuration view, a Service Mode that mirrors the major manufacturers' service UIs, a scanning water tank that plots dose from any machine configuration, and a calibration water tank for TG-51 / TRS-398. Varian and Elekta screens, an account per user.
Two editions — and how you buy each one
The Education Edition is included with most training products — Physics Teaching Packages, and the Physics and Advanced Service courses.
The Service Edition is bought on its own, or with the other digital twin modules — the simulator gains the inputs to match your own accelerator.
A fixed machine model supplied by Linax, bundled with every SIMAC training product — for trainees, physics teams, and new service hires. Not a service aid.
- Practice beam tuning and see cause-and-effect safely
- Build intuition for how each subsystem shapes the beam
- Repeatable, remotely deliverable competency training
Not sold separately — it is included in the training products that come with SIMAC.
Everything in the Education Edition, plus a calibration tab that matches the simulator to your specific accelerator. This is the base clinical product — start here, then add modules as you need them.
- Connect a QA deviation to its probable fault and subsystem
- Reproduce a fault to test corrective actions before doing them live
- Prioritize service actions · support return-to-service · reduce downtime
What you can do
Change any machine setting — steering, bending magnet, energy, gun current — and investigate changes to your outputs.
- See the effect on PDD, flatness / symmetry profiles, TMR / TPR, and dose calibration
- Set baseline operating values at installation and match the machine response
- Troubleshoot beam-generation faults and understand dose response before repairs
- Keep the model current with the linac lifecycle (PMIs, return-to-service)
What's included
- Both Varian & Elekta screens · everyone gets their own account
- SIMAC Learning always included
- Scanning and calibration water tank tabs included — both come with SIMAC Machine at no extra cost; the commissioning-grade SIMAC Water Tank is the separately-sold Digital Twin product
- Configurable Service Screen, oscilloscope, console, live response
- Manual or automatic servoing · detailed outputs (electron energies, RF powers, water temperature)
- Service Edition: individual machine & component configuration · lifecycle management
What it does — and doesn't do today
SIMAC Machine models the beam-generation chain in depth. The physics model's precision will keep improving as more user data is collected. It does not yet model the whole machine.
- ›Change settings and see QA outputs respond, with no risk to a real machine
- ›Models the beamline across Varian & Elekta configurations
- ›Service Edition calibrates to your accelerator for service work
- ›MLC, CBCT / kV imaging, and accessory interfaces
- ›Control-system electronics (PCBs), networks, and power distribution
- ›Treatment-head / carousel motions and vendor-specific interlocks
- ›Live mode creates profiles at a single depth; out-of-field dose is not modelled
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
Per machine, per beam model · requires SIMAC Machine · buy as a bundle
Four interfaces — graphical Machine Config, Service Mode, a scanning water tank, and a calibration water tank — on both Varian and Elekta screens, with an individual account per user. SIMAC Learning is always included.
A physical linac or a treatment planning system. The Education Edition is fixed and for teaching; the Service Edition (Digital Twin) adds the calibration tab that matches it to your machine.
