From: Comparison of simple and complex liver intensity modulated radiotherapy
Axial (left panels) and Coronal (right panels) slices of acceptable index and simple IMRT, showing the six fraction, lowest isodose covering 0.5 cc PTV (orange), the 30 Gy isodose (dark blue) and 10 Gy isodose (beige) surrounding the PTV (pink colorwash). Examples are shown of a small lesion typical of liver SBRT (A), where loss of dose conformation of higher isodoses may have larger effects on normal tissue function, as compared to a larger lesion near bowel treated to lower doses (B).
