Treatment plan at baseline (top row), predicted plan (middle row) and adapted plan (bottom row) at one particular fraction. Objectives and clinical constraints according to the institutional protocol for SBRT in prostate cancer can be seen on the right of the figure, where a comparison of the values achieved by the predicted and adapted plan is shown. Values which do not meet the preset values are highlighted in yellow. At the bottom of the figure, a DVH comparison of the three plans is shown. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
