DOSIMETRY INTERSTITIAL TREATMENTS

➢ Monoplanar or volume implants

➢ Monoplanar implant geometry could follow the Manchester System rules

➢ In volume implants, the knowledge of the Paris System ( Pirquen et al, 1978 )

dosimetry details are useful

➢ With a perfect geometry biological planning becomes practicable

➢ Rules for biological planning:

- Information on the different dose needs in PTV

- Max. D ref distance to the applicator surface < 1cm - Max. dose on the applicator surface 400% D ref
