What is an acceptably smoothed fluence? Dosimetric and delivery considerations for dynamic sliding window IMRT
BACKGROUND The study summarised in this report aimed to investigate the interplay between fluence complexity, dose calculation algorithms, dose calculation spatial resolution and delivery characteristics (monitor units, effective field width and dose delivery against dose prediction agreement) was investigated. A sample set of complex planning cases was selected and tested using a commercial tr...

متن کاملDosimetry limitations and pre-treatment dose profile correction for sliding window IMRT
Background: This work investigated the dosimetry limitations of the random and systematic uncertainties of sliding window (SW) intensity modulated radiation therapy (IMRT). Materials and Methods: A Varian 21EX linear accelerator, Pinnacle3 treatment planning system and radiographic film dosimetry was used. The limitations of the SW were studied using beam modulation ranging from 2 to 10...
متن کاملDosimetric evaluation of field-in-field and sliding-window IMRT in endometrium cancer patients with a new approach for the conformity index
Background: Purpose of the study is to evaluate field-in-field (FIF) and sliding-window intensity modulated radiation therapy (SW-IMRT) treatment plans in terms of homogeneity index (HI), conformity index (CI) and normal tissue doses for organs at risk (OAR) in patients with endometrial carcinoma along with deriving a new expression for CI. Materials and Methods: Four different FIF plans with d...
