Figure 8
Dose distributions obtained in the human knee joint and breast with the MC (centre) and the TLE method (right), with 108 incident photon counts. (a), (b) and (c): knee joint; (d), (e) and (f): breast. (a), (d) are the sample models derived from experimental CT data, (b), (e) are the dose maps obtained with the TLE method, while (c), (f) are the maps computed with the equivalent MC method. In (a), the region marked (1) has been assigned to the formalin solution, (2) to the adipose tissue, (3) to muscle and (4) to the cortical and trabecular bone. In (d), (5) has been assigned to glandular tissue, (6) represents the adipose tissue, (7) is the tumour and (8) is the formalin solution. The dose scales in (b), (c), (e) and (f) are normalized to unity. |
