Commissioning
Linear accelerators, planning systems, and new modalities commissioned to national guidance, on a date, and independently checked before the first patient.
Commissioning, as it stands
Done by the clinical physicist
The onsite physicist carries the clinical load. Commissioning runs nights and weekends, and go-live moves with it.
One set of eyes
Beam data and models are checked by the person who collected them. The first independent review is the accreditation survey.
Vendor acceptance, department commissioning
The vendor proves the machine meets specification. Clinical commissioning, modeling, and validation are left to the department.
Data that cannot be found
Beam data on a laptop, no commissioning report, and nothing for the next physicist or the next surveyor.

Linear Accelerators

- Acceptance TestingVendor specifications verified and documented before the vendor leaves.
- Beam Data CollectionPhoton and electron data collected and reviewed against reference data, per AAPM TG-106.
- Absolute CalibrationOutput calibrated to AAPM TG-51 and cross-checked by a second physicist.
- MLC and ImagingMLC, IGRT, and image-guidance systems commissioned and baselined for ongoing QA, per TG-142 and TG-198.
- Beam MatchingMachines matched across a department or a network so plans move between them.
Treatment Planning Systems

- Beam ModelingModels built from your measured data, not vendor golden data.
- Dose ValidationCalculation validated against measurement, per AAPM MPPG 5.a.
- IMRT and VMAT ValidationDelivery accuracy confirmed per TG-119 before the first modulated plan.
- End-to-End TestsSimulation to treatment, measured in phantom, for every technique released.
- Upgrades and MigrationsSoftware upgrades and system migrations re-validated before clinical use.
Specialty and New Programs
Learn more
- Stereotactic ProgramsSRS and SBRT commissioned end to end, including small-field dosimetry per TG-155.
- Special ProceduresTBI, TSET, and electron programs commissioned and documented.
- BrachytherapyHDR source, applicators, and planning commissioned per TG-56 and licensed with the state.
- Simulation and Surface GuidanceCT simulator (TG-66), 4D CT, and surface guidance commissioned with the department.
- New CentersShielding design, licensure, policies, and commissioning delivered as one project to a go-live date.
Six steps, one date
Plan
Scope, equipment, timeline, and go-live date agreed with leadership before the vendor arrives.
Accept
Vendor acceptance witnessed and documented. Deficiencies resolved before commissioning starts.
Measure
Beam data collected by a TNM commissioning team, not the clinical physicist, so the clinic keeps running.
Model and validate
Planning system modeled and validated against measurement, technique by technique.
Independent check
A second TNM physicist reviews every dataset, model, and calibration before release.
Go live
Commissioning report, QA baselines, and staff training delivered. First patient treated on the date.
Sized to the equipment
Linac commissioning
Acceptance through first patient, with beam data, TPS model, and report delivered.
Beam-matched replacement
New machine matched to the existing fleet. Software and hardware upgrades re-validated.
Program start-up
SRS, SBRT, brachytherapy, or special procedures commissioned and taken to first patient.
Facility to first patient
Shielding, licensure, commissioning, policies, and go-live under one agreement.
View page →Commissioned on a date. Checked independently.
Every dataset, model, and calibration reviewed by a second TNM physicist before release. The commissioning report belongs to you.
- Go-live date set with leadership and held.
- Clinical physics keeps treating while TNM commissions.
- Report, QA baselines, and training delivered at go-live.
Submit the equipment, planning system, techniques, and target go-live date, in confidence.
TNM responds with a commissioning plan and a date.
