Abstract: A sensing apparatus for sensing the presence of a radioactive source, or check- dummy- or sensor cable, at a point along mg the sensing apparatus during a brachytherapy procedure. The sensing apparatus comprises a transfer tube comprising a first end and IC a second end. The second end being downstream of the first end. The sensing apparatus further comprises sensing means operable to detect the presence of a radioactive source, or check- dummy- or sensor cable, at a point downstream of the first end of the transfer tube. The reason for the plurality of “prisms” or the semispheres, is that they are orientation independent to the light fibers, simplifying assembly. Alternatively the plurality of prisms may be substituted by two half-spherical “prisms”. Between the prisms, a light blocking surface need to be placed to avoid optical short circuits.

Abstract: An afterloading device for effectuating a brachytherapy treatment, comprising a first elongated flexible transport element, arranged to maneuver a radiation source between a storage position inside the afterloading device and a treatment position outside the afterloading device, the afterloading device further comprising a second elongated flexible transport element, having at least one transducer, the second transport element being arranged to move the at least one transducer between a first transducer position and a second transducer position.
