Background and purpose To study if MOSkin detectors coupled to a trans-rectal ultrasound
(TRUS) probe may be used for in vivo dosimetry on the rectal wall surface during US-based
HDR prostate brachytherapy and to quantify possible discrepancies between planned and
delivered doses. Materials and methods MOSkins are a specific type of MOSFET dosimeter
optimized to measure dose in steep dose gradients on interfaces. Two MOSkins were
assembled on a TRUS probe used for on-line treatment planning. Measurements of the …
