title: [Three-dimensional radiation planning. Studies on clinical integration].
abstract: The routine use of three-dimensional treatment planning was evaluated in a clinical project funded by the German Krebshilfe at the Radiological Department of the University of Heidelberg. 166 patients entered the prospective study within 14 months, 155 of them were treated according to the 3D-plans. More than 50% of the patients had thoracic tumors, followed by pelvic tumors. One medicine physicist and one specially trained technician performed the treatment planning. The target volumes were contoured in the CT slices at the planning computer by the responsible radiotherapists. A mean of 6.5 hours per patient was necessary for all planning procedures, however, this time consumption shows a trend toward less time of only four hours including about ten optimization steps. Meanwhile approximately 20 to 30% of all computer assisted planning are performed in 3D, corresponding to about one plan per day. The achieved time consumption is a clinically accepted quantity, that allows the introduction of 3D-planning into clinical routine.
