Fig. 31.14: Example for a dose plan for a flap made with five parallel plastic tubes for contact brachytherapy (shown in Fig. 4). Prescription dose is to 3mm under the skin surface. The distance is calculat- ed by adding 5mm bolus plus 1mm radius, total 9mm from the axis. The 150% isodose curve does not arrive to the skin.

Fig. 31.15: Isodose curves for a nasal mould with five plastic tubes. High doses remain inside the mould, with a more homogeneous distribution on the skin surface.
