User requirements on CT-based computed dose planning systems in radiation therapy.

The expanding use of computers in radiation therapy procedures, especially the rapidly increasing use of digital CT information, necessitates the coordination of the different systems in order to facilitate their developments. In order to define necessary demands for tomorrow a Nordic cooperation was initiated 1981 by NORDFORSK (Nordic co-operative organization for applied research), and a group of physicians and physicists having their daily work in this field of medicine and physics was invited to produce a report on 'User requirements on CT-based computerized dose planning systems in radiotherapy'. The work has been done within the frame of NORDFORSK's activities. The working group has been independent of the existing commissions and associations in the radiology field, but it has taken into consideration recommendations that have been given by or are being produced by other organizations.
