title: An aid to computerization of Heyman's afterloading system.
abstract: The authors describe a new type of dummy implant for use in the Heyman afterloading system. Inactive dummies with the same dimensions as the radioactive sources are loaded into the capsules before obtaining the orthogonal radiographs. The actual sources are not inserted until computer verification of satisfactory dose distribution has been obtained.
