PTV of the selected plan in the LOP (green), and the PTVs of the MRI_5mm (red) and the MRI_3mm (blue) strategy overlaid on a transversal MRI. The low-risk CTV on the transversal MRI is indicated by the dashed yellow line. In this example, due to intrafraction bladder filling, the coverage of the low-risk CTV was insufficient for the MRI_3mm strategy (D98% < 95%), while it was sufficient for the MRI_5mm and LOP strategy
