Abstract
A sensing apparatus for sensing the presence of a radioactive source, or check-dummy- or sensor cable, at a point along the sensing apparatus during a brachytherapy procedure. The sensing apparatus comprises a transfer tube comprising a first end and 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.
