Accuracy - a market in radiotherapy. Reasons, requirements, clinical practice

Creators

  • 1. Krankenhaus Nordwest, Frankfurt am Main (Germany, F.R.). Radio-Onkologische Klinik

Description

Accuracy requirements are specified in accordance with survival curves drawn up on the basis of clinical experience and data. Sigmoidal dose-response curves are established with the aid of the survival curves, giving information on tumour decline and the radiation effects induced in patients. In accordance with the ICRU report of 1984, Quality Assurance of External Beam Therapy, accuracy verification takes into account the two different criteria of tolerance level and action level. The dosimetric overall uncertainty is to be kept below 8 p.c. (DG)

Abstract (German)

Die Grundlage fuer die Spezifizierung von Genauigkeitsanforderungen stellen auf klinischen Daten basierende Ueberlebenskurven dar. Aus diesen Ueberlebenskurven lassen sich die bekannten sigmoidalen Dosiswirkungskurven erstellen, die fuer die Tumorheilung wie fuer das Risiko von Strahlenfolgen gelten. Nach dem Stand des ICRU-Reports ueber die Qualitaetssicherung in der Strahlentherapie wird wie bei der geraetetechnischen Qualitaetssicherung zwischen einem Toleranzniveau und einem Aktionsniveau unterschieden. Die dosimetrische Gesamtunsicherheit soll 8% nicht ueberschreiten. (DG)
