TI  - Accelerator beam data commissioning equipment and procedures: report of the 
      TG-106 of the Therapy Physics Committee of the AAPM.
PG  - 4186-215
AB  - For commissioning a linear accelerator for clinical use, medical physicists are 
      faced with many challenges including the need for precision, a variety of testing 
      methods, data validation, the lack of standards, and time constraints. Since 
      commissioning beam data are treated as a reference and ultimately used by 
      treatment planning systems, it is vitally important that the collected data are 
      of the highest quality to avoid dosimetric and patient treatment errors that may 
      subsequently lead to a poor radiation outcome. Beam data commissioning should be 
      performed with appropriate knowledge and proper tools and should be independent 
      of the person collecting the data. To achieve this goal, Task Group 106 (TG-106) 
      of the Therapy Physics Committee of the American Association of Physicists in 
      Medicine was formed to review the practical aspects as well as the physics of 
      linear accelerator commissioning. The report provides guidelines and 
      recommendations on the proper selection of phantoms and detectors, setting up of 
      a phantom for data acquisition (both scanning and no-scanning data), procedures 
      for acquiring specific photon and electron beam parameters and methods to reduce 
      measurement errors (<1%), beam data processing and detector size convolution for 
      accurate profiles. The TG-106 also provides a brief.discussion on the emerging 
      trend in Monte Carlo simulation techniques in photon and electron beam 
      commissioning. The procedures described in this report should assist a qualified 
      medical physicist in either measuring a complete set of beam data, or in 
      verifying a subset of data before initial use or for periodic quality assurance 
      measurements. By combining practical experience with theoretical discussion, this 
      document sets a new standard for beam data commissioning.
