title: [Determination of target volume for dosimetric planning in stereotactic radiosurgery].
abstract: Stereotactic radiosurgery needs an accurate determination of the target volumes to be irradiated and of sensitive volumes to be spared: position, external boundaries, internal volume. These parameters can be obtained by using either projection imaging (radiographs, digital angiography), or tomographic imaging (magnetic resonance imaging, computerized tomography). The authors describe the methods used in these different imaging modalities and the problems encountered in target determination. Methods of validations are described. Results obtained on phantoms and on actual target volume are given and discussed.
