Due to its higher mean energy of 1.25 MeV, less scatter is produced and therefore, the radial dose function of Co-60 shows slightly smaller values than Ir-192 with 0.35 MeV (see figure 1). The treatment with Co-60 leads to lower dose to organs at risk (OAR) than with Ir-192. Eckert & Ziegler BEBIG provides customers with an expansive portfolio of applicators suitable for the use with Co-60 and Ir-192. Complete Range of Clinical ApplicationsĬo-60 has been shown to be a good choice for treating gynaecological, rectal, prostate, breast, oesophagus, skin, and other body sites. The treatment planning systems of Eckert & Ziegler BEBIG are able to calculate dose distributions of Co-60 for all applicators shielded and unshielded. Accordingly, TG-43 data (Dosimetry of interstitial brachytherapy sources: Recommendations of the AAPM Radiation Therapy Committee Task Group 43), dosimetric measurements, and Monte Carlo calculations are available and have been implemented in HDRplus and SagiPlan®. The Co-60 source is not only clinically well proven, it is physically well understood and extensively analysed as well. This design, modern even by today ‘s standards, enables treatment with applicators of the smallest diameters and narrow curvatures. In 2003, Eckert & Ziegler BEBIG successfully designed and introduced the first miniaturized Co-60 source.
Since its introduction, Co-60 has achieved tremendous success and has continued to evolve to support modern HDR brachytherapy needs. In 1962, Walstam introduced the first concept of a remote afterloader equipped with Co-60. In addition to the Ir 192 source, SagiNova also offers the option of the well-established and clinically proven Co 60 isotope for all HDR brachytherapy treatments.Ĭobalt-60 sources are exclusively available for the SagiNova ® afterloaders.
