Positional errors of single-directional measurement as functions of true depth of absorption change. (a) Positional errors of simulation experiment. Conventions are identical as in Figs. 6(a-c). (b) Positional errors of simulation experiment evaluated separately according to the four categories shown in Fig. 4(c). Conventions are identical as in Figs. 6(d-f). (c) Positional errors of phantom experiment. Conventions are identical as in Fig. 9.
