Steerable needles in prostate brachytherapy: From sketch to MDR-compliant batch

Brachytherapy (BT) is a safe and effective technique to treat prostate cancer that has not spread outside the prostate gland (localised prostate cancer). Nonetheless, in current clinical practice hazards can arise in positioning the BT needles in the prostate for the purpose of irradiation. Intermediate structures can block access to the...

Application of luminophores in sandtransport-studies

The quantitative determination of bed-material-transport by means of tracers has been considered. For a stationary-stochastical transport-condition the dispersion of tracers has been described by a diffusion-equation of the gradienttype. The parameters of the dispersion-model are derived from the measured concentrations by a least-squares...
