  1. 1. Contouring & planning variability in stereotactic radiosurgery : How to assess and address the weakest link in stereotactic radiosurgery?

    Author : Helena Sandström; Iuliana Toma-Dasu; David Schlesinger; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stereotactic radiosurgery; contouring variability; robust treatment planning; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : The use of stereotactic radiosurgery (SRS) employing one or a few fractions of high doses of radiation has continuously increased due to the technical development in dose delivery and morphological and functional imaging. As the target volume in SRS is usually defined without margins, the treatment success critically depends on accurate definition and contouring of the target volume and organs at risk (OARs) which are commonly situated in the proximity of the target making their precise delineation particularly important in order to limit possible normal tissue complications.

  2. 2. Contouring variability in radiosurgery - dosimetric and radiobiological implications

    Author : Helena Sandström; Iuliana Toma-Dasu; Mike Partridge; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : The use of Stereotactic Radiation Therapy (SRT) employing one large fraction of radiation, as in stereotactic radiosurgery (SRS), or few fractions of high doses, has continuously increased due to the technical development and the progress in dose delivery complemented by the positive clinical experience. The success of stereotactic radiation therapy depends on many clinical, dosimetric and radiobiological factors. READ MORE
