DIN EN 61217:2015-11

The International Standard has been prepared by IEC/SC 62C "Equipment for radiotherapy, nuclear medicine and radiation dosimetry". This standard applies to equipment and data related to the process of teleradiotherapy, including patient image data used in relation with radiotherapy treatment planning systems, radiotherapy simulators, isocentric gamma beam therapy equipment, isocentric medical electron accelerators, and non-isocentric equipment when relevant. The object of this standard is to define a consistent set of coordinate systems for use throughout the process of teleradiotherapy, to define the marking of scales (where provided), to define the movements of equipment used in this process, and to facilitate computer control when used. In addition to the previous edition, this standard contains specifications for an imager coordinate system and a focal spot coordinate system for image-controlled radiotherapy facilities. An important advantage of a standard coordinate system is its contribution to safety in irradiation planning. The scales defined in this standard are consistent with the coordinate systems in this document. This standard is published separately from the safety standards of the IEC 60601 series. It is not a safety standard in the sense of the IEC 60601 series and does not contain any quality requirements. Therefore, the present requirements will not appear in future editions of the IEC 60601-2 series standards, which deal exclusively with safety requirements. The committee responsible for this standard is NA 080-00-15 GA NAR/DKE Gemeinschaftsausschuss "Strahlentherapie" (NAR/DKE Joint Committee "Radiotherapy") of the Radiology Standards Committee (NAR) at DIN, the German Institute for Standardization, collaborating with Deutsche Röntgengesellschaft (German Radiological Society) and the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE and Deutsche Gesellschaft für Nuklearmedizin e. V. (DGN) (German Society of Nuclear Medicine), Deutsche Gesellschaft für Medizinische Physik e. V. (DGMP) (German Society for Medical Physics) and Deutsche Gesellschaft für Radioonkologie e. V. (DEGRO) (German Society for Radio Oncology).
