AB  - Recent technological developments in linear accelerators (linacs) and their 
      imaging systems have made it possible to routinely perform stereotactic 
      radiotherapy (SRT) treatments. To ensure the security and quality of the 
      treatments, national and international recommendations have been written. This 
      review focuses on the recommendations of the report 91 of the International 
      Commission on Radiation Units (ICRU) on stereotactic treatments with small photon 
      beams and proposes to answer the question of the eligibility of the commercially 
      available accelerators for the treatment of extra-cranial SRT (SBRT). The ICRU 91 
      report outlines important features needed to respect the constraints, which are 
      high intensity photon beam, integrated image-guidance, high mechanical accuracy 
      of the linac, multileaf collimator with reduced leaf width, bundled motion 
      management and bundled 6 Dimensional "robotic" couch tabletop. Most of the 
      contemporary linacs meet these recommendations, in particular, stereotactic 
      dedicated linacs, or modern gantry-based linacs equipped with 3 dimensional 
      cone-beam CT imaging and 2D-stereoscopic planar imaging. Commercially available 
      ring-based linacs have some limitations: they offer only coplanar treatments, and 
      couch movements are limited to translations and, some have limited imaging 
      equipment and no ability to manage intrafraction motion. However, for performing 
      SBRT, non-coplanar irradiations are not mandatory, contrarily to intracranial 
      stereotactic irradiations. Furthermore, patients' rotations can be corrected, 
      thanks to real-time adaptive radiotherapy available on MRI-linacs. Finally, 
      significant improvements are expected in the short term to compensate the 
      weaknesses of the current devices.
