Multicriteria optimization of the spatial dose distribution.
PURPOSE Treatment planning for radiation therapy involves trade-offs with respect to different clinical goals. Typically, the dose distribution is evaluated based on few statistics and dose-volume histograms. Particularly for stereotactic treatments, the spatial dose distribution represents further criteria, e.g., when considering the gradient between subregions of volumes of interest. The auth...

Objectives: Successful aging is a positive, inner feeling and satisfaction with the past and present lives. Thus, the study was conducted to determine the predicting factors of the successful aging in a sample of Iranian elderly. Materials and methods: This cross-sectional and descriptive-analytic study was conducted on 291 elderly people in Qazvin in 2018 selected using two-stage cluster samp...
متن کاملIdeal spatial radiotherapy dose distributions subject to positional uncertainties.
In radiotherapy a common method used to compensate for patient setup error and organ motion is to enlarge the clinical target volume (CTV) by a 'margin' to produce a 'planning target volume' (PTV). Using weighted power loss functions as a measure of performance for a treatment plan, a simple method can be developed to calculate the ideal spatial dose distribution (one that minimizes expected lo...
متن کاملEffect of uniform magnetic field on dose distribution in the breast radiotherapy
Background: To reduce the dose to normal tissues surrounding the treated breast, a uniform magnetic field was used within a humanoid phantom in breast radiotherapy. Materials and Methods: Monte Carlo simulations were performed with GEANT4, irradiating humanoid phantoms in a magnetic field. To reconstruct phantoms, computed tomography (CT) data slices of four patients were used for the Monte Car...
