PTV margin determination in conformal SRT of intracranial lesions
The planning target volume (PTV) includes the clinical target volume (CTV) to be irradiated and a margin to account for uncertainties in the treatment process. Uncertainties in miniature multileaf collimator (mMLC) leaf positioning, CT scanner spatial localization, CT-MRI image fusion spatial localization, and Gill-Thomas-Cosman (GTC) relocatable head frame repositioning were quantified for the...
متن کاملTreatment accuracy without rotational setup corrections in intracranial SRT
The aim of this study was to evaluate the impact of actual rotational setup errors on dose distributions in intracranial stereotactic radiotherapy (SRT) with different alternatives for treatment position selection. A total of 38 SRT fractions from 18patients were retrospectively evaluated with rotational setup errors obtained from actual treatments. The planning computed tomography (CT) images ...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولIntracranial lesions mimicking neoplasms.
CONTEXT A broad spectrum of nonneoplastic conditions can mimic a brain tumor, both clinically and radiologically. In this review we consider these, taking into consideration the following etiologic categories: infection, demyelination, vascular diseases, noninfectious inflammatory disorders, and iatrogenic conditions. We give an overview of such diseases, which represent a potential pitfall for...
متن کاملWire Guided Biopsy for Determination of Margin Status with Breast Lesions
Due to the widespread implementation of breast screening programs and improvements in diagnostic imaging, approximately 25-35% of breast cancers are non-palpable at diagnosis (Skinner et al., 2001). However, because of these breast screening programs and improvements there is an increase in the incidence of breast lesions which have to be clarified histopathologically. As well as nonpalpable br...
