title: [Xeroradiographic field controls on a telecobalt unit in the thoracic, abdominal and pelvic region and in the extremities].
abstract: After having modified the method of direct field control by the telecobalt unit for the cranial region and the neck, it has been possible to effect these controls for the thoracic, abdominal, and pelvic region, too. If two sources of radiation are used, it is decisive to cover with lead the zones of half-shadow on the field limits. The technology of direct field control and the advantages for planning and control of the radiation therapy are described.
