Linear Accelerator Commissioning

The responsibilities of the medical physicist seem to grow with every iteration of new technology.  These responsibilities can be overwhelming in the clinic day to day, but more so when accepting and commissioning a new or existing linac.  LinearPhysics can provide commissioning services tailored to your specific needs, allowing the medical physicist to continue with their clinical duties, while being engaged with the commissioning process.  These services can include all or a subset of the following services:

– Acceptance Testing

– Data Acquisition

– Data Modeling

– Model validation

– TG-51 absolute dose calibration and OSLD exposure

– End to end testing of your treatment delivery and planning

– Data Book


Additional Commissioning Service:

– Beam data validation for Beam Matched machines

– Establishing baseline data for daily, monthly and annual QA based on TG-142

– IMRT and VMAT commissioning

– Portal dosimetry commissioning

– SRS MLC and Cone based commissioning and validation

– Total body Irradiation

– Total skin Irradiation

– Radiation Shielding Design and post-Installation Survey



  • Commissioning performed by ABR board certified physicists
  • Measured data comparison against vendor reference data with clear readable analysis
  • Commissioning package can be customized to meet your financial budgets
  • Available to discuss results and questions


We can use your scanning system and measurement equipment, or provide our scanning system, and any associated measurement equipment.

Our services are based on recommendations of the American Association of Physicists in Medicine, including reports such as:

Task Group 51 Protocol for Clinical Reference Dosimetry of High-energy Photon and Electron beams
Task Group 106 report: Accelerator Beam Data Commissioning Equipment and Procedures
Task Group 142 report: Quality assurance of medical accelerators
