A fast radiotherapy paradigm for anal cancer with volumetric modulated arc therapy (VMAT) (2009)

Stieler, Florian, Wolff, Dirk, Lohr, Frank, Steil, Volker, Abo-Madyan, Yasser, Lorenz, Friedlieb, ...

Abstract Background/Purpose Radiotherapy (RT) volumes for anal cancer are large and of moderate complexity when organs at risk (OAR) such as testis, small bowel and bladder are at least partially to...

Development of a neuro-fuzzy technique for automated parameter optimization of inverse treatment planning (2009)

Stieler, Florian, Yan, Hui, Lohr, Frank, Wenz, Frederik, Yin, Fang-Fang

Abstract Background Parameter optimization in the process of inverse treatment planning for intensity modulated radiation therapy (IMRT) is mainly conducted by human planners in order to create a...

Intrafraction motion of the prostate during an IMRT session: a fiducial-based 3D measurement with Cone-beam CT (2008)

Boda-Heggemann, Judit, Köhler, Frederick, Wertz, Hansjörg, Ehmann, Michael, Hermann, Brigitte, Riesenacker, Nadja, ...

Abstract Background Image-guidance systems allow accurate interfractional repositioning of IMRT treatments, however, these may require up to 15 minutes. Therefore intrafraction motion might have an...

Preoperative thrombocytosis predicts poor survival in patients with glioblastoma (2007)

Brockmann, Marc A., Giese, Alf, Mueller, Kathrin, Kaba, Finjap Janvier, Lohr, Frank, Weiss, Christel, ...

Thrombocytosis, which is defined as a platelet count greater than 400 platelets/nl, has been found to be an independent predictor of shorter survival in various tumors. Release of growth factors from...

Evaluation of possible prostate displacement induced by pressure applied during transabdominal ultrasound image acquisition (2006)

Dobler, Barbara, Mai, Sabine, Ross, Christine, Wolff, Dirk, Wertz, Hansjörg, Lohr, Frank, ...

BACKGROUND AND PURPOSE: For accurate positioning of the prostate in external radiotherapy, transabdominal ultrasound localization and positioning systems are available. Reports have stated that probe...
