Dose to points

• Traditional Brachy Systems: • Paris “System”: a set of rules to obtain suitable dose distributions. • For different regular source patterns, basal points are defined in regions of dose plateau or minimum • In HDR it evolved to Steeping Source Dosimetry System (SSDS) ( Van der Laarse 1997 ) • Adopted by ICRU 58
