Table description For each of the organs considered, separate tables of dose conversion factors are given in Appendix B for the baby and in Appendices D and E for the child phantom. Each of these tables contains 7 columns. The first column describes the single sections with respect to their z-coordinate within the phantom. Together with the relation of the phantoms' z- coordinates to certain anatomical landmarks (which are given in Appendix A for the baby and in Appendix C for the child), this characterises the position of the respective section in the body unequivocally. It should be noted that increasing z-coordinates are oriented downwards in the body. The next column shows the percentage of the organ volume included in the single section, i.e. the ratio of the organ being directly irradiated during scanning a respective 1 cm wide slice. For smaller organs, this value is zero for most sections; for tissues spread throughout the body (as e.g. skin, skeleton and red bone marrow) at each single slice position certain proportions are directly irradiated. Two pairs of columns of conversion factors are following, one pair for each of the two radiation qualities considered. Within each of these pairs, the first column presents conversion factors for full 360° rotation of the fan beam, the second column those for 180° rotation around the front side of the body. The conversion factors listed in the tables represent mean organ doses normalised to air kerma free in air on the axis of rotation, resulting from a scan of the respective body section.
10 The last column in each table presents an average value of the standard deviations of the conversion factors (expressed in percentage) estimated from the Monte Carlo calculation. The length of the tables varies due to the different dimensions of the organs in height. The organ dose conversion factors are highest at scan positions where part of the organ is directly irradiated and decrease rapidly above and below this region. The sections are listed only as long as the respective conversion factors amount to at least 0.00005 and are omitted beyond these borders. Doses resulting from slices outside the region listed in the tables can be neglected as their contribution is insignificant.
