List of organs as defined in ICRP 103 (Ref. 2) with tissue weighting factors translated into tissue weighting factors for MOSFET spots associated with the organ. The three region locations i = 1, 2, and 3 of the spots within the phantom correspond, respectively, to MOSFET placements cranial-to-thorax, thorax, and caudal-to-thorax.
