Fig 6.20C-E: Reporting in Endo-oesophageal Brachytherapy (centred, concentric applicator) Dose reporting for different Applicator Diameters (AD) 6, 10, 15 mm (C,D,E) and different prescription practice (at 10 mm from Source Axis; at Applicator Surface (AS) +5mm). The Depth of the Prescribed Dose (PD), of the Reference Dose (RD) and the AS are indicated, in addition AD and the radius of the applicators (r: 3, 5, 7.5 mm). The Length of the Reference Volume (RVL) is defined as the length of the 90%-isodose at the reference depth of 5 mm. Independent of the varying individual dose presciption (C-E), for reporting the reference dose should always be given at the RD, which is 5 mm from the AS. Dose at the AS should also be reported (compare for details Fig 5.9 and 26.3-8).
