Linac and TPS commissioning service

Linear Accelerators and Treatment Planning Systems commissioning service – saving you time


Over 15 years
commissioning experience


UK registered, Health and Care Professions Council, clinical scientists


State of the art equipment


Bespoke comissioning plans

 

Giving your team access to our extensive expertise 

Linac

  • Save valuable time by working with NPL on Commissioning Linear Accelerators (Linac) and Treatment Planning Systems (TPS).
  • We have over 15 years’ experience, gained through ongoing research and industry collaborations.
  • As radiotherapy providers, our team of radiation dosimetry and medical physics experts can help you speed up your commissioning process.  
  • You will have access to our primary standards and a dedicated commissioning team. Our UK registered HCPC clinical scientists, combined with our state-of-the-art equipment, deliver accelerated beam data collection programmes, tailored to your needs, without compromising on quality. 
  • Additionally, we assist with Linac customer acceptance (CAT) and matching processes, and provide an independent dosimetric subset of measurements to establish your Linac quality assurance (QA) baseline.

 

Linac teamOur team will support your junior medical physicists, by providing an overview and practical experience of the commissioning process.

Understanding your needs

We understand the requirements for most of the TPS available in the market, both independent and linked to Linac manufacturers. We design the project for measurements with TPS modelling purposes, but also with model verification intentions.  

We offer flexible scheduling to accommodate your installation timeline and assist local specialists by configuring fields that deviate from the standard settings in Linac consoles. 

Overview of the services available 

A typical set of data for X-rays and electron beams will be acquired according to the TPS measurements requirements, including: 

  • Profiles and depth ionisation and dose curves, electron isodose charts
  • Square, rectangular and asymmetric - open and wedged fields
  • Output factor measurements, including small fields
  • Dose point measurements in reference and non-references conditions
  • Scans of shaped fields for model verification purposes and fine tuning of beam model parameters.

We can work with most 3D scanning solutions available. Regardless of the choice, NPL will create the relevant measurement queues for the tasks involved. Based upon your preference, we can work with your local measurement systems and detectors or bring our own, including 3D water phantoms and
associated software.

We have a set of detectors suitable for every type of measurements:

  • Cylindrical and plane parallel ionisation chambers
  • Small volume ionisation chambers for measurements in small fields
  • Stereotactic, electron and photon diodes
  • Secondary standard chamber and electrometers for relative and absolute output measurements

If you need to commission a mobile Linac or low-energy and medium-energy X-ray equipment, it will be possible to perform the beam data collection process in our laboratories in Teddington.

How we work together

  • You will typically have one or two members of our staff on-site for two to four weeks, according to your measurement requirements.
  • If you are having multiple installations, we provide two teams working simultaneously on two different Linacs.
  • Shortly after completing on-site work, we will securely transfer raw and processed data, either on a CD, USB drive, or via a large zip file through a secure server.
  • We also provide a comprehensive report with all the relevant details that will contribute towards your department commissioning portfolio.
  • We keep you involved in the commissioning process and up to date with our progress. 

Providing ongoing support

Following on from the delivery of your commissioning needs, NPL can further assist with any queries you have and, if required, can deliver a consultancy-based solution. 

This service is available for conventional Linacs and other radiotherapy devices. We also have a range of complementary services, such as photon and electron independent verification audits, as well as other clinical audits.
