Abstract

We present the details of a new linear array dosimeter consisting of a chain of semiconductors mounted on an ultra-thin (50μm thick) flexible substrate and housed in an intracavitary catheter. The Semiconductors, manufactured by NMRC Cork, have not been packaging and incorporate a passivation layer that allows them to be mounted on the substrate using Flip-chip-bonding. This paper reports, for the first time, the construction of a multiple (ten) detector array suited to in vivo dosimetry in the rectum, esophagus and vagina during external beam radiotherapy, as well as being adaptable to in vivo dosimetry during brachytherapy and diagnostic radiology.
