Technical note: Dosimetric study of a new Co-60 source used in brachytherapy
2007
The purpose of this study is to obtain the dosimetric parameters of a new Co-60 source used in high dose rate brachytherapy and manufactured by BEBIG (Eckert & Ziegler BEBIG GmbH, Germany). The Monte Carlo method has been used to obtain the dose rate distribution in the updated TG-43U1 formalism of the American Association of Physicists in Medicine. In addition, to aid the quality control process on treatment planning systems (TPS), a two-dimensional rectangular dose rate table, coherent with the TG-43U1 dose calculation formalism, is given. These dosimetric data sets can be used as input data of the TPS calculations and to validate them.
SU-FF-T-41: Monte Carlo Dosimetric Study of the New BEBIG Co-60 HDR Source
2005
Purpose: The use of high dose rate brachytherapy (HDR) is a highly extended practice today, being the Ir‐192 the most widely extended isotope used for this type of practice although Co‐60 is also available for HDR. The purpose of this study is to obtain the dosimetric parameters of the Co‐60 source used by the BEBIG MultiSource remote afterloader (BEBIG GmbH, Germany) for which there is no dosimetric data available in the literature. It is recommended that accurate dose distribution data, based on a realistic geometry and on the mechanical characteristics of the source, should be obtained by an appropriate method, experimental or Monte Carlo, to be used as input in the HDR Treatment Plannin…
Die kombinierte operative und radiotherapeutische Behandlung (CORT) von Beckenwandrezidiven: Erfahrungsbericht nach 3 Jahren
1993
CORT has been developed to treat recurrent gynaecological malignancies infiltrating the pelvic wall unilaterally. The surgical part consists of: (i) staging laparotomy/lymphadenectomy, (ii) maximum tumour resection at the pelvic wall and exenteration of infiltrated central pelvic organs, (iii) implantation of guiding tubes on the residual tumour/tumour bed on the pelvic wall, (iv) pelvic wall plasty with muscle, musculocutaneous and omentum flaps, (v) operative reconstruction of bowel, bladder and perineo-vulvo-vaginal functions. Radiation is performed as interstitial high dose rate brachytherapy through the implanted tubes. Patients without prior pelvic irradiation receive in addition, who…
