Modulation indices and plan delivery accuracy of volumetric modulated arc therapy [PDF]

Journal of Applied Clinical Medical Physics, 2019
AbstractPurposeWe evaluated the performance of various modulation indices (MI) for volumetric modulated arc therapy (VMAT) to predict plan delivery accuracy.MethodsThe specific indices evaluated were MI quantifying the mechanical uncertainty (MIt), MI quantifying the mechanical and dose calculation uncertainties (MIc), MI for station parameter ...

Volumetric Modulated Arc Therapy (VMAT) på venstresidig brystkreft med spredning til regionale lymfeknuter [PDF]

, 2020
Bakgrunn: Studier har vist høyere dødelighet av hjertesykdom blant pasienter som fikk strålebehandling mot venstre bryst sammenlignet med de som fikk behandling mot høyre bryst. Pustestyrt behandlingsteknikk reduserer stråledosen til hjertet.

A dosimetric comparison of volumetric modulated arc therapy with three-dimensional conformal radiotherapy in the treatment of cervical cancer

South African Journal of Oncology, 2021
Background: External beam radiotherapy (EBRT) is essential in the management of locally advanced cervical cancer (LACC). Volumetric modulated arc therapy (VMAT) is thought to achieve higher conformity to the planned target volume (PTV) and better sparing

A synthetic diamond diode in volumetric modulated arc therapy dosimetry [PDF]

Medical Physics, 2013
Purpose:The aim of this work is to investigate the behavior of a single crystal diamond diode (SCDD) for volumetric modulated arc therapy (VMAT) dose verifications. This delivery technique is one of the most severe test of a dosimeter performance due to the modulation of the dose rate achieved by simultaneously changing the velocity of the gantry and ...
