This International 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 ME EQUIPMENT used in this process, and to facilitate
computer control when used.
