Quality assurance during interstitial brachytherapy: in vivo dosimetry using MOSFET dosimeters.

Conclusions: The deviations between planned and measured dose values were markedly influenced by the proximity of the detector to the PTV because where the edema exerts, the greatest influence on the tube applicator geometry. The positioning of the patient during irradiation must correspond to the positioning in the planning CT. Further studies are needed to investigate the role of in vivo dosimetry during interstitial brachytherapy as a routine procedure. PMID: 30038643 [PubMed]
