Revisiting fetal dose during radiation therapy: evaluating treatment techniques and a custom shield [JACMP, 17(5), 2016].

The authors would like to report an error in an entry for Table 7.1 Under the column labeled “PD without shield (cGy),” the first entry, 8.10, is off by a factor of ten. This entry should read 0.81.

Table 7

The estimated fetal doses with and without the fetal shield based on the measured clinical plans listed in Table 2. A distance of 50 cm was maintained between the CT reference and the ion chamber used for these measurements, as shown in Fig. 2(a). The distance displayed in this Table is the measured distance between the center of the PTV and the ion chamber for each clinical setup
